From cd28ab6a4e50a7601d22752aa7ce0c8197b10bdf Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 16 Aug 2005 16:36:49 -0700 Subject: [PATCH 0001/2756] [PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load.

Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ.

Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating.

The Linux kernel only offloads the TCP and UDP +checksums (and always performs the pseudo header checksums), so +the driver only supports checksumming for TCP/IP and UDP/IP +packets. Use ethtool to enable or disable this feature for RX +and TX. + +VLAN + +In order to use VLAN, please consult Linux documentation on +configuring VLANs. The gianfar driver supports hardware insertion and +extraction of VLAN headers, but not filtering. Filtering will be +done by the kernel. + +MULTICASTING + +The gianfar driver supports using the group hash table on the +TSEC (and the extended hash table on the eTSEC) for multicast +filtering. On the eTSEC, the exact-match MAC registers are used +before the hash tables. See Linux documentation on how to join +multicast groups. + +PADDING + +The gianfar driver supports padding received frames with 2 bytes +to align the IP header to a 16-byte boundary, when supported by +hardware. + +ETHTOOL + +The gianfar driver supports the use of ethtool for many +configuration options. You must run ethtool only on currently +open interfaces.

Due to this, we would like to process received packets for every interface in the same NAPI poll handler, so we need a pseudo-device to schedule polling on. What the driver currently does is that it always schedules polling for the first network interface in the list, and processes packets for every interface in the poll handler for that first interface -- however, this scheme breaks down if the first network interface happens to not be up, since netif_rx_schedule_prep() checks netif_running(). sky2 apparently has the same issue, and Stephen Hemminger suggested a way to work around this: create a variant of netif_rx_schedule_prep() that does not check netif_running(). I implemented this locally and called it netif_rx_schedule_prep_notup(), and it seems to work well, but it's something that probably not everyone would be happy with. The ixp2000 is an ARM CPU with a high-speed network interface in the CPU itself (full duplex 4Gb/s or 10Gb/s depending on the IXP model.) The CPU package also contains 8 or 16 (again depending on the IXP model) 'microengines', which are somewhat primitive but very fast and efficient processor cores which can be used to offload various things from the main CPU. This driver makes the high-speed network interface in the CPU visible and usable as a regular linux network device. Currently, it only supports the Radisys ENP2611 IXP board, but adding support for other board types should be fairly easy.

This removes the sysfs file 'ignore_nice' and in its place creates a 'ignore_nice_load' entry that defaults to '0'; meaning nice'd processes _are_ counted towards the 'business' calculation. WARNING: this obvious breaks any userland tools that expected ignore_nice' to exist, to draw attention to this fact it was concluded on the mailing list that the entry should be removed altogether so the userland app breaks and so the author can build simple to detect workaround.

To do this the CPU must have the capability to -switch the frequency very fast. - - +switch the frequency very quickly. There are a number of sysfs file +accessible parameters: + +sampling_rate: measured in uS (10^-6 seconds), this is how often you +want the kernel to look at the CPU usage and to make decisions on +what to do about the frequency. Typically this is set to values of +around '10000' or more. + +show_sampling_rate_(min|max): the minimum and maximum sampling rates +available that you may set 'sampling_rate' to. + +up_threshold: defines what the average CPU usaged between the samplings +of 'sampling_rate' needs to be for the kernel to make a decision on +whether it should increase the frequency. For example when it is set +to its default value of '80' it means that between the checking +intervals the CPU needs to be on average more than 80% in use to then +decide that the CPU frequency needs to be increased. + +sampling_down_factor: this parameter controls the rate that the CPU +makes a decision on when to decrease the frequency. When set to its +default value of '5' it means that at 1/5 the sampling_rate the kernel +makes a decision to lower the frequency. Five "lower rate" decisions +have to be made in a row before the CPU frequency is actually lower. +If set to '1' then the frequency decreases as quickly as it increases, +if set to '2' it decreases at half the rate of the increase. + +ignore_nice_load: this parameter takes a value of '0' or '1', when set +to '0' (its default) then all processes are counted towards towards the +'cpu utilisation' value. When set to '1' then processes that are +run with a 'nice' value will not count (and thus be ignored) in the +overal usage calculation. This is useful if you are running a CPU +intensive calculation on your laptop that you do not care how long it +takes to complete as you can 'nice' it and prevent it from taking part +in the deciding process of whether to increase your CPU frequency. + + +2.5 Conservative +---------------- + +The CPUfreq governor "conservative", much like the "ondemand" +governor, sets the CPU depending on the current usage. It differs in +behaviour in that it gracefully increases and decreases the CPU speed +rather than jumping to max speed the moment there is any load on the +CPU. This behaviour more suitable in a battery powered environment. +The governor is tweaked in the same manner as the "ondemand" governor +through sysfs with the addition of: + +freq_step: this describes what percentage steps the cpu freq should be +increased and decreased smoothly by. By default the cpu frequency will +increase in 5% chunks of your maximum cpu frequency. You can change this +value to anywhere between 0 and 100 where '0' will effectively lock your +CPU at a speed regardless of its load whilst '100' will, in theory, make +it behave identically to the "ondemand" governor. + +down_threshold: same as the 'up_threshold' found for the "ondemand" +governor but for the opposite direction. For example when set to its +default value of '20' it means that if the CPU usage needs to be below +20% between samples to have the frequency decreased. 3.

It includes some sanity checks in case the measured value is out of range and assigns a safe value of 500uSec that should still be enough on problematics chipsets (current testing report values ~200uSec). The measurement is currently done in speedstep_get_freqs in order to avoid further unnecessary transitions and in the hope it'll come handy for SMI also.

Today the answer is: It depends. On i386: SMP kernel - It is always the boot frequency UP kernel - Scales with the frequency change and shows that was last set. On x86_64: There is one single variable cpu_khz that gets written by all the CPUs. So, the frequency set by last CPU will be seen on /proc/cpuinfo of all the CPUs in the system. What you see also depends on whether you have constant_tsc capable CPU or not. On ia64: It is always boot time frequency of a particular CPU that gets displayed. The patch below changes this to: Show the last known frequency of the particular CPU, when cpufreq is present. If cpu doesnot support changing of frequency through cpufreq, then boot frequency will be shown. The patch affects i386, x86_64 and ia64 architectures.

The main benefit is for a bus with more than one SBP-2 device: SBP-2 reconnects will be performed before SBP-2 logins, thus have a much higher chance to succeed, and their SCSI devices will not be blocked much longer than necessary. This was demonstrated for Linux 2.4 by Dave Cinege a while ago. A better approach would be to perform time-consuming probes in parallel by a subthread. I actually plan to implement this for sbp2 but it may take a while to get that done and tested. Until then, this tweak is a huge improvement for users with multiple SBP-2 devices.

Previously, this was done by each user by manually initializing a qc, issueing it, waiting for its completion and handling errors. In addition to obvious code factoring, using ata_exec_internal() fixes the following bugs. * qc not freed on issue failure * ap->qactive clearing could race with the next internal command * race between timeout handling and irq * ignoring error condition not represented in tf->status Also, qc & hardware are not accessed anymore once it's completed, making internal commands more conformant with general semantics. ata_exec_internal() also makes it easy to issue internal commands from multiple threads if that becomes necessary. This patch only implements ata_exec_internal(). A following patch will convert all users. Signed-off-by: Tejun Heo -- Jeff, all patches have been regenerated against upstream branch as of today. (575ab52a218e4ff0667a6cbd972c3af443ee8713) Also, I took out a debug printk from ata_exec_internal (don't know how that one got left there).

Especially when both libata and the legacy IDE drivers try to drive ports on the same device, since that makes DMA rather difficult. This patch addresses the problem by allowing the user to control which driver binds to the ports in a combined mode configuration. In many cases, they'll probably want the libata driver to control both ports since it can use DMA for talking with ATAPI devices (when libata.atapi_enabled=1 of course). It also allows the user to get old school behavior by letting the legacy IDE driver bind to both ports. But neither is forced, the patch doesn't change current behavior unless one of combined_mode=ide or combined_mode=libata is passed on the boot line. Either of those options may require you to access your devices via different device nodes (/dev/hd* in the ide case and /dev/sd* in the libata case), though of course if you have udev installed nicely you may not notice anything. :) Let me know if the documentation is too cryptic, I'd be happy to expand on it if necessary. I think most users will want to boot with 'combined_mode=libata' and add 'options libata atapi_enabled=1' to their modules.conf to get good DVD playing and disk behavior (haven't tested CD or DVD writing though). I'd much rather things behave sanely by default (i.e. DMA for devices on both ports), but apparently that's difficult given the various chip bugs and hardware configs out there (not to mention that people's drives may suddenly change from /dev/hdc to /dev/sdb), so this boot option may be the correct long term fix.

Fix ipr to detect this scenario by reading the adapter's interrupt mask register and the microprocessor interrupt register. If the interrupt mask register indicates that interrupts are enabled or the reset alert bit is set when the card is probed, this means the card is in an unknown state and we hard reset the card.

Includes run time attribute to enable mode. - Enable runtime writable hba settings for coallescing and delay parameters Customers have requested a mode in the driver to run strictly polled. This is generally to support an environment where the server is extremely loaded and is looking to reclaim some cpu cycles from adapter interrupt handling. This patch adds a new "poll" attribute, and the following behavior: if value is 0 (default): The driver uses the normal method for i/o completion. It uses the firmware feature of interrupt coalesing. The firmware allows a minimum number of i/o completions before an interrupt, or a maximum time delay between interrupts. By default, the driver sets these to no delay (disabled) or 1 i/o - meaning coalescing is disabled. Attributes were provided to change the coalescing values, but it was a module-load time only and global across all adapters. This patch allows them to be writable on a per-adapter basis. if value is 1 : Interrupts are left enabled, expecting that the user has tuned the interrupt coalescing values. When this setting is enabled, the driver will attempt to service completed i/o whenever new i/o is submitted to the adapter. If the coalescing values are large, and the i/o generation rate steady, an interrupt will be avoided by servicing completed i/o prior to the coalescing thresholds kicking in. However, if the i/o completion load is high enough or i/o generation slow, the coalescion values will ensure that completed i/o is serviced in a timely fashion. if value is 3 : Turns off FCP i/o interrupts altogether. The coalescing values now have no effect. A new attribute "poll_tmo" (default 10ms) exists to set the polling interval for i/o completion. When this setting is enabled, the driver will attempt to service completed i/o and restart the interval timer whenever new i/o is submitted. This behavior allows for servicing of completed i/o sooner than the interval timer, but ensures that if no i/o is being issued, then the interval timer will kick in to service the outstanding i/o.

This utilizes the hostdata area that is hung off of scsi_target and scsi_device for saving unique firmware mapping. This will be required for supporting new Fibre and SPI transport support.

I think the scsi_execute_* functions should eventually take a request_queue and be placed some place where the dm-multipath hw_handler can use them if that failover code is going to stay in the kernel.

And make buffer allocation code obey all queue limits so we can find out about problems before calling scsi_execute_async. Currently, sg.c could allocate a buffer that is too large, and send the request to scsi_execute_async. scsi_execute_async will then check it against all the queue limits and return a failure in this case.

This is the same as last time as it was posted, but with Kai's patches merged and we now pass the bytes value to scsi_execute_async. TODO: - move DIO code to common place or make block layers usable for ULDs. - move buffer allocation code to common place for all ULDs to use. And make buffer allocation code handle all queue limits so we can find out about problems before calling scsi_execute_async. - move indirect (copy_to/from_user) paths commone place or make block layers usable for ULDs.

This patch corrects some corner cases in managing the RAE/RRE bits in the mthca qp context. These bits need to be zero if the user requests max_dest_rd_atomic of zero. The bits need to be restored to the value implied by the qp access flags attribute in a previous (or the current) modify-qp command if the dest_rd_atomic variable is changed to non-zero. In the current implementation, the following scenario will not work: RESET-to-INIT set QP access flags to all disabled (zeroes) INIT-to-RTR set max_dest_rd_atomic=10, AND set qp_access_flags = IB_ACCESS_REMOTE_READ | IB_ACCESS_REMOTE_ATOMIC The current code will incorrectly take the access-flags value set in the RESET-to-INIT transition. We can simplify, and correct, this IB_QP_ACCESS_FLAGS handling: it is always safe to set qp access flags in the firmware command if either of IB_QP_MAX_DEST_RD_ATOMIC or IB_QP_ACCESS_FLAGS is set, so let's just set it to the correct value, always.

Since block/scsi_ioctl.c SG_IO was already testing against max_sectors and SCSI-ml was setting max_sectors and max_hw_sectors to the same value this does not change any scsi SG_IO behavior. It only prepares ll_rw_blk.c, scsi_ioctl.c and bio.c for when SCSI-ml begins to set a valid max_hw_sectors for all LLDs. Today if a LLD does not set it SCSI-ml sets it to a safe default and some LLDs set it to a artificial low value to overcome memory and feedback issues. Note: Since we now cap max_sectors to BLK_DEF_MAX_SECTORS, which is 1024, drivers that used to call blk_queue_max_sectors with a large value of max_sectors will now see the fs requests capped to BLK_DEF_MAX_SECTORS.

Remove when PageReserved is removed */ BUG_ON(PageReserved(page)); I was using /dev/zero as input and it triggers this. When I used a file as input, this did not trigger. Should this BUG_ON be removed? In the same log I noticed that there was another ->sg_segs inconsistency. Also, the field ->last_SRpnt was not reset when scsi_execute_async() failed. This caused the error message "Async command already active" later and prevented proper close. While doing the changes, I noticed that the current code (since 2.6.0-test4) does not set the pages dirty when reading with direct i/o. All of these st problems (including the one I sent earlier) are fixed in the patch at the end of this message. These fixes should probably be included already in 2.6.15. After these fixes, the tape seems to operate as expected. Without other changes, the largest block size with sym53c896 SCSI adapter is 384 kB. The maximum number of sg segments is set to 96 and clustering is disabled in the driver. 96 x 4 kB = 384 kB. OK. I enabled clustering and set max_sectors to 10000 in the SCSI HBA driver.

For example, if module source name is current.c, idle_stack.c or etc., we have a bad KBUILD_MODNAME value. For example, KBUILD_MODNAME will be "get_current()" instead of "current", or "(init_thread_union.stack)" instead of "idle_task". The trick is to define a stringify macro on the commandline - named KBUILD_STR for namespace reasons - and then to stringify the module name. There are a few uses of KBUILD_MODNAME throughout the tree but the usage is for debug and will not be harmed by this change so left untouched for now. While at it KBUILD_BASENAME was changed too. Any spinlock usage in the unix module would have created wrong section names without it. Usage in spinlock.h fixed so it no longer stringify KBUILD_BASENAME.

After analyzing logs from such machines, it appears that the overtemp code is a bit too quick at shutting the machine down when reaching the critical temperature (tmax + 8) and doesn't leave the fan enough time to actually cool it down. This happens if the temperature of a CPU suddenly rises too high in a very short period of time, or occasionally on boot (that is the CPUs are already overtemp by the time the driver loads). This patches makes the code a bit more relaxed, leaving a few seconds to the fans to do their job before kicking the machine shutown.

However, asm/param.h is sometimes used in userland (it is included indirectly from ), so your commit pollutes the userland namespace with tons of CONFIG_FOO macros.

Set the master volume to about 6 or 8% in alsamixer. This will attenuate the output enough for better sound quality. Note: Only stereo enabled at present. The distortion is caused by the output path after the DSP adding 12dB gain to the output while still in digital mode, resulting in wrap around distortion.

This adds the chip ID to the snd_powermac driver such that it is recognized as a Toonie (I don't know if that's correct, but it's the only one that makes it work at all). and sorts the ID lists numerically. NOTE: This chip is only minimally supported at this point; it has system beep support and very low volume speaker output, and that's about it.

Modules: AC97 Codec,ATIIXP driver,Intel8x0 driver This patch adds a new quirk for ac97 hardware that combines the existing AC97_TUNE_MUTE_LED and AC97_TUNE_HP_ONLY quirks. This is needed for several current HP laptops. Additionally, it adds the HP nx6125 to the AC97_TUNE_MUTE_LED list. Fixed for the latest version of ALSA by Takashi Iwai .

Where sysfs is a filesystem-based view of +kernel objects, configfs is a filesystem-based manager of kernel +objects, or config_items. + +With sysfs, an object is created in kernel (for example, when a device +is discovered) and it is registered with sysfs. Its attributes then +appear in sysfs, allowing userspace to read the attributes via +readdir(3)/read(2). It may allow some attributes to be modified via +write(2). The important point is that the object is created and +destroyed in kernel, the kernel controls the lifecycle of the sysfs +representation, and sysfs is merely a window on all this. + +A configfs config_item is created via an explicit userspace operation: +mkdir(2). It is destroyed via rmdir(2). The attributes appear at +mkdir(2) time, and can be read or modified via read(2) and write(2). +As with sysfs, readdir(3) queries the list of items and/or attributes. +symlink(2) can be used to group items together. Unlike sysfs, the +lifetime of the representation is completely driven by userspace. The +kernel modules backing the items must respond to this. + +Both sysfs and configfs can and should exist together on the same +system. One is not a replacement for the other. + +[Using configfs] + +configfs can be compiled as a module or into the kernel. You can access +it by doing + + mount -t configfs none /config + +The configfs tree will be empty unless client modules are also loaded. +These are modules that register their item types with configfs as +subsystems. Once a client subsystem is loaded, it will appear as a +subdirectory (or more than one) under /config. Like sysfs, the +configfs tree is always there, whether mounted on /config or not. + +An item is created via mkdir(2). The item's attributes will also +appear at this time. readdir(3) can determine what the attributes are, +read(2) can query their default values, and write(2) can store new +values. Like sysfs, attributes should be ASCII text files, preferably +with only one value per file. The same efficiency caveats from sysfs +apply. Don't mix more than one attribute in one attribute file. + +Like sysfs, configfs expects write(2) to store the entire buffer at +once. When writing to configfs attributes, userspace processes should +first read the entire file, modify the portions they wish to change, and +then write the entire buffer back. Attribute files have a maximum size +of one page (PAGE_SIZE, 4096 on i386). + +When an item needs to be destroyed, remove it with rmdir(2). An +item cannot be destroyed if any other item has a link to it (via +symlink(2)). Links can be removed via unlink(2). + +[Configuring FakeNBD: an Example] + +Imagine there's a Network Block Device (NBD) driver that allows you to +access remote block devices. Call it FakeNBD. FakeNBD uses configfs +for its configuration. Obviously, there will be a nice program that +sysadmins use to configure FakeNBD, but somehow that program has to tell +the driver about it. Here's where configfs comes in. + +When the FakeNBD driver is loaded, it registers itself with configfs. +readdir(3) sees this just fine: + + # ls /config + fakenbd + +A fakenbd connection can be created with mkdir(2). The name is +arbitrary, but likely the tool will make some use of the name. Perhaps +it is a uuid or a disk name: + + # mkdir /config/fakenbd/disk1 + # ls /config/fakenbd/disk1 + target device rw + +The target attribute contains the IP address of the server FakeNBD will +connect to. The device attribute is the device on the server. +Predictably, the rw attribute determines whether the connection is +read-only or read-write. + + # echo 10.0.0.1 > /config/fakenbd/disk1/target + # echo /dev/sda1 > /config/fakenbd/disk1/device + # echo 1 > /config/fakenbd/disk1/rw + +That's it. That's all there is. Now the device is configured, via the +shell no less. + +[Coding With configfs] + +Every object in configfs is a config_item. A config_item reflects an +object in the subsystem. It has attributes that match values on that +object. configfs handles the filesystem representation of that object +and its attributes, allowing the subsystem to ignore all but the +basic show/store interaction. + +Items are created and destroyed inside a config_group. A group is a +collection of items that share the same attributes and operations. +Items are created by mkdir(2) and removed by rmdir(2), but configfs +handles that. The group has a set of operations to perform these tasks + +A subsystem is the top level of a client module. During initialization, +the client module registers the subsystem with configfs, the subsystem +appears as a directory at the top of the configfs filesystem. A +subsystem is also a config_group, and can do everything a config_group +can. + +[struct config_item] + + struct config_item { + char *ci_name; + char ci_namebuf[UOBJ_NAME_LEN]; + struct kref ci_kref; + struct list_head ci_entry; + struct config_item *ci_parent; + struct config_group *ci_group; + struct config_item_type *ci_type; + struct dentry *ci_dentry; + }; + + void config_item_init(struct config_item *); + void config_item_init_type_name(struct config_item *, + const char *name, + struct config_item_type *type); + struct config_item *config_item_get(struct config_item *); + void config_item_put(struct config_item *); + +Generally, struct config_item is embedded in a container structure, a +structure that actually represents what the subsystem is doing. The +config_item portion of that structure is how the object interacts with +configfs. + +Whether statically defined in a source file or created by a parent +config_group, a config_item must have one of the _init() functions +called on it. This initializes the reference count and sets up the +appropriate fields. + +All users of a config_item should have a reference on it via +config_item_get(), and drop the reference when they are done via +config_item_put(). + +By itself, a config_item cannot do much more than appear in configfs. +Usually a subsystem wants the item to display and/or store attributes, +among other things. For that, it needs a type. + +[struct config_item_type] + + struct configfs_item_operations { + void (*release)(struct config_item *); + ssize_t (*show_attribute)(struct config_item *, + struct configfs_attribute *, + char *); + ssize_t (*store_attribute)(struct config_item *, + struct configfs_attribute *, + const char *, size_t); + int (*allow_link)(struct config_item *src, + struct config_item *target); + int (*drop_link)(struct config_item *src, + struct config_item *target); + }; + + struct config_item_type { + struct module *ct_owner; + struct configfs_item_operations *ct_item_ops; + struct configfs_group_operations *ct_group_ops; + struct configfs_attribute **ct_attrs; + }; + +The most basic function of a config_item_type is to define what +operations can be performed on a config_item. All items that have been +allocated dynamically will need to provide the ct_item_ops->release() +method. This method is called when the config_item's reference count +reaches zero. Items that wish to display an attribute need to provide +the ct_item_ops->show_attribute() method. Similarly, storing a new +attribute value uses the store_attribute() method. + +[struct configfs_attribute] + + struct configfs_attribute { + char *ca_name; + struct module *ca_owner; + mode_t ca_mode; + }; + +When a config_item wants an attribute to appear as a file in the item's +configfs directory, it must define a configfs_attribute describing it. +It then adds the attribute to the NULL-terminated array +config_item_type->ct_attrs. When the item appears in configfs, the +attribute file will appear with the configfs_attribute->ca_name +filename. configfs_attribute->ca_mode specifies the file permissions. + +If an attribute is readable and the config_item provides a +ct_item_ops->show_attribute() method, that method will be called +whenever userspace asks for a read(2) on the attribute. The converse +will happen for write(2). + +[struct config_group] + +A config_item cannot live in a vaccum. The only way one can be created +is via mkdir(2) on a config_group. This will trigger creation of a +child item. + + struct config_group { + struct config_item cg_item; + struct list_head cg_children; + struct configfs_subsystem *cg_subsys; + struct config_group **default_groups; + }; + + void config_group_init(struct config_group *group); + void config_group_init_type_name(struct config_group *group, + const char *name, + struct config_item_type *type); + + +The config_group structure contains a config_item. Properly configuring +that item means that a group can behave as an item in its own right. +However, it can do more: it can create child items or groups. This is +accomplished via the group operations specified on the group's +config_item_type. + + struct configfs_group_operations { + struct config_item *(*make_item)(struct config_group *group, + const char *name); + struct config_group *(*make_group)(struct config_group *group, + const char *name); + int (*commit_item)(struct config_item *item); + void (*drop_item)(struct config_group *group, + struct config_item *item); + }; + +A group creates child items by providing the +ct_group_ops->make_item() method. If provided, this method is called from mkdir(2) in the group's directory. The subsystem allocates a new +config_item (or more likely, its container structure), initializes it, +and returns it to configfs. Configfs will then populate the filesystem +tree to reflect the new item. + +If the subsystem wants the child to be a group itself, the subsystem +provides ct_group_ops->make_group(). Everything else behaves the same, +using the group _init() functions on the group. + +Finally, when userspace calls rmdir(2) on the item or group, +ct_group_ops->drop_item() is called. As a config_group is also a +config_item, it is not necessary for a seperate drop_group() method. +The subsystem must config_item_put() the reference that was initialized +upon item allocation. If a subsystem has no work to do, it may omit +the ct_group_ops->drop_item() method, and configfs will call +config_item_put() on the item on behalf of the subsystem. + +IMPORTANT: drop_item() is void, and as such cannot fail. When rmdir(2) +is called, configfs WILL remove the item from the filesystem tree +(assuming that it has no children to keep it busy). The subsystem is +responsible for responding to this. If the subsystem has references to +the item in other threads, the memory is safe. It may take some time +for the item to actually disappear from the subsystem's usage. But it +is gone from configfs. + +A config_group cannot be removed while it still has child items. This +is implemented in the configfs rmdir(2) code. ->drop_item() will not be +called, as the item has not been dropped. rmdir(2) will fail, as the +directory is not empty. + +[struct configfs_subsystem] + +A subsystem must register itself, ususally at module_init time. This +tells configfs to make the subsystem appear in the file tree. + + struct configfs_subsystem { + struct config_group su_group; + struct semaphore su_sem; + }; + + int configfs_register_subsystem(struct configfs_subsystem *subsys); + void configfs_unregister_subsystem(struct configfs_subsystem *subsys); + + A subsystem consists of a toplevel config_group and a semaphore. +The group is where child config_items are created. For a subsystem, +this group is usually defined statically. Before calling +configfs_register_subsystem(), the subsystem must have initialized the +group via the usual group _init() functions, and it must also have +initialized the semaphore. + When the register call returns, the subsystem is live, and it +will be visible via configfs. At that point, mkdir(2) can be called and +the subsystem must be ready for it. + +[An Example] + +The best example of these basic concepts is the simple_children +subsystem/group and the simple_child item in configfs_example.c It +shows a trivial object displaying and storing an attribute, and a simple +group creating and destroying these children. + +[Hierarchy Navigation and the Subsystem Semaphore] + +There is an extra bonus that configfs provides. The config_groups and +config_items are arranged in a hierarchy due to the fact that they +appear in a filesystem. A subsystem is NEVER to touch the filesystem +parts, but the subsystem might be interested in this hierarchy. For +this reason, the hierarchy is mirrored via the config_group->cg_children +and config_item->ci_parent structure members. + +A subsystem can navigate the cg_children list and the ci_parent pointer +to see the tree created by the subsystem. This can race with configfs' +management of the hierarchy, so configfs uses the subsystem semaphore to +protect modifications. Whenever a subsystem wants to navigate the +hierarchy, it must do so under the protection of the subsystem +semaphore. + +A subsystem will be prevented from acquiring the semaphore while a newly +allocated item has not been linked into this hierarchy. Similarly, it +will not be able to acquire the semaphore while a dropping item has not +yet been unlinked. This means that an item's ci_parent pointer will +never be NULL while the item is in configfs, and that an item will only +be in its parent's cg_children list for the same duration. This allows +a subsystem to trust ci_parent and cg_children while they hold the +semaphore. + +[Item Aggregation Via symlink(2)] + +configfs provides a simple group via the group->item parent/child +relationship. Often, however, a larger environment requires aggregation +outside of the parent/child connection. This is implemented via +symlink(2). + +A config_item may provide the ct_item_ops->allow_link() and +ct_item_ops->drop_link() methods. If the ->allow_link() method exists, +symlink(2) may be called with the config_item as the source of the link. +These links are only allowed between configfs config_items. Any +symlink(2) attempt outside the configfs filesystem will be denied. + +When symlink(2) is called, the source config_item's ->allow_link() +method is called with itself and a target item. If the source item +allows linking to target item, it returns 0. A source item may wish to +reject a link if it only wants links to a certain type of object (say, +in its own subsystem). + +When unlink(2) is called on the symbolic link, the source item is +notified via the ->drop_link() method. Like the ->drop_item() method, +this is a void function and cannot return failure. The subsystem is +responsible for responding to the change. + +A config_item cannot be removed while it links to any other item, nor +can it be removed while an item links to it. Dangling symlinks are not +allowed in configfs. + +[Automatically Created Subgroups] + +A new config_group may want to have two types of child config_items. +While this could be codified by magic names in ->make_item(), it is much +more explicit to have a method whereby userspace sees this divergence. + +Rather than have a group where some items behave differently than +others, configfs provides a method whereby one or many subgroups are +automatically created inside the parent at its creation. Thus, +mkdir("parent) results in "parent", "parent/subgroup1", up through +"parent/subgroupN". Items of type 1 can now be created in +"parent/subgroup1", and items of type N can be created in +"parent/subgroupN". + +These automatic subgroups, or default groups, do not preclude other +children of the parent group. If ct_group_ops->make_group() exists, +other child groups can be created on the parent group directly. + +A configfs subsystem specifies default groups by filling in the +NULL-terminated array default_groups on the config_group structure. +Each group in that array is populated in the configfs tree at the same +time as the parent group. Similarly, they are removed at the same time +as the parent. No extra notification is provided. When a ->drop_item() +method call notifies the subsystem the parent group is going away, it +also means every default group child associated with that parent group. + +As a consequence of this, default_groups cannot be removed directly via +rmdir(2). They also are not considered when rmdir(2) on the parent +group is checking for children. + +[Committable Items] + +NOTE: Committable items are currently unimplemented. + +Some config_items cannot have a valid initial state. That is, no +default values can be specified for the item's attributes such that the +item can do its work. Userspace must configure one or more attributes, +after which the subsystem can start whatever entity this item +represents. + +Consider the FakeNBD device from above. Without a target address *and* +a target device, the subsystem has no idea what block device to import. +The simple example assumes that the subsystem merely waits until all the +appropriate attributes are configured, and then connects. This will, +indeed, work, but now every attribute store must check if the attributes +are initialized. Every attribute store must fire off the connection if +that condition is met. + +Far better would be an explicit action notifying the subsystem that the +config_item is ready to go. More importantly, an explicit action allows +the subsystem to provide feedback as to whether the attibutes are +initialized in a way that makes sense. configfs provides this as +committable items. + +configfs still uses only normal filesystem operations. An item is +committed via rename(2). The item is moved from a directory where it +can be modified to a directory where it cannot. + +Any group that provides the ct_group_ops->commit_item() method has +committable items. When this group appears in configfs, mkdir(2) will +not work directly in the group. Instead, the group will have two +subdirectories: "live" and "pending". The "live" directory does not +support mkdir(2) or rmdir(2) either. It only allows rename(2). The +"pending" directory does allow mkdir(2) and rmdir(2). An item is +created in the "pending" directory. Its attributes can be modified at +will. Userspace commits the item by renaming it into the "live" +directory. At this point, the subsystem recieves the ->commit_item() +callback. If all required attributes are filled to satisfaction, the +method returns zero and the item is moved to the "live" directory. + +As rmdir(2) does not work in the "live" directory, an item must be +shutdown, or "uncommitted". Again, this is done via rename(2), this +time from the "live" directory back to the "pending" one. The subsystem +is notified by the ct_group_ops->uncommit_object() method. + + diff --git a/Documentation/filesystems/configfs/configfs_example.c b/Documentation/filesystems/configfs/configfs_example.c new file mode 100644 index 00000000000..f3c6e4946f9 --- /dev/null +++ b/Documentation/filesystems/configfs/configfs_example.c @@ -0,0 +1,474 @@ +/* + * vim: noexpandtab ts=8 sts=0 sw=8: + * + * configfs_example.c - This file is a demonstration module containing + * a number of configfs subsystems. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

AOP_TRUNCATED_PAGE tells the caller that the callee has unlocked the page and that the operation should be tried again with a new page. OCFS2 uses this to detect and work around a lock inversion in its aop methods. There should be no change in behaviour for methods that don't return AOP_TRUNCATED_PAGE. WRITEPAGE_ACTIVATE is also prepended with AOP_ for consistency and they are made enums so that kerneldoc can be used to document their semantics.

The OCFS2 dlm exposes a VMS style API, though things have been simplified internally. The only lock levels implemented currently are NLMODE, PRMODE and EXMODE.

The +rest of this document will be geared towards those who want to use +dlmfs for easy to setup and easy to use clustered locking in +userspace. + +Setup +===== + +dlmfs requires that the OCFS2 cluster infrastructure be in +place. Please download ocfs2-tools from the above url and configure a +cluster. + +You'll want to start heartbeating on a volume which all the nodes in +your lockspace can access. The easiest way to do this is via +ocfs2_hb_ctl (distributed with ocfs2-tools). Right now it requires +that an OCFS2 file system be in place so that it can automatically +find it's heartbeat area, though it will eventually support heartbeat +against raw disks. + +Please see the ocfs2_hb_ctl and mkfs.ocfs2 manual pages distributed +with ocfs2-tools. + +Once you're heartbeating, DLM lock 'domains' can be easily created / +destroyed and locks within them accessed. + +Locking +======= + +Users may access dlmfs via standard file system calls, or they can use +'libo2dlm' (distributed with ocfs2-tools) which abstracts the file +system calls and presents a more traditional locking api. + +dlmfs handles lock caching automatically for the user, so a lock +request for an already acquired lock will not generate another DLM +call. Userspace programs are assumed to handle their own local +locking. + +Two levels of locks are supported - Shared Read, and Exlcusive. +Also supported is a Trylock operation. + +For information on the libo2dlm interface, please see o2dlm.h, +distributed with ocfs2-tools. + +Lock value blocks can be read and written to a resource via read(2) +and write(2) against the fd obtained via your open(2) call. The +maximum currently supported LVB length is 64 bytes (though that is an +OCFS2 DLM limitation). Through this mechanism, users of dlmfs can share +small amounts of data amongst their nodes. + +mkdir(2) signals dlmfs to join a domain (which will have the same name +as the resulting directory) + +rmdir(2) signals dlmfs to leave the domain + +Locks for a given domain are represented by regular inodes inside the +domain directory. Locking against them is done via the open(2) system +call. + +The open(2) call will not return until your lock has been granted or +an error has occurred, unless it has been instructed to do a trylock +operation. If the lock succeeds, you'll get an fd. + +open(2) with O_CREAT to ensure the resource inode is created - dlmfs does +not automatically create inodes for existing lock resources. + +Open Flag Lock Request Type +--------- ----------------- +O_RDONLY Shared Read +O_RDWR Exclusive + +Open Flag Resulting Locking Behavior +--------- -------------------------- +O_NONBLOCK Trylock operation + +You must provide exactly one of O_RDONLY or O_RDWR. + +If O_NONBLOCK is also provided and the trylock operation was valid but +could not lock the resource then open(2) will return ETXTBUSY. + +close(2) drops the lock associated with your fd. + +Modes passed to mkdir(2) or open(2) are adhered to locally. Chown is +supported locally as well. This means you can use them to restrict +access to the resources via dlmfs on your local node only. + +The resource LVB may be read from the fd in either Shared Read or +Exclusive modes via the read(2) system call. It can be written via +write(2) only when open in Exclusive mode. + +Once written, an LVB will be visible to other nodes who obtain Read +Only or higher level locks on the resource. + +See Also +======== +http://opendlm.sourceforge.net/cvsmirror/opendlm/docs/dlmbook_final.pdf + +For more information on the VMS distributed locking API. diff --git a/fs/ocfs2/dlm/Makefile b/fs/ocfs2/dlm/Makefile index 2a5274bcc8b..ce3f7c29d27 100644 --- a/fs/ocfs2/dlm/Makefile +++ b/fs/ocfs2/dlm/Makefile @@ -1,6 +1,8 @@ EXTRA_CFLAGS += -Ifs/ocfs2 -obj-$(CONFIG_OCFS2_FS) += ocfs2_dlm.o +obj-$(CONFIG_OCFS2_FS) += ocfs2_dlm.o ocfs2_dlmfs.o ocfs2_dlm-objs := dlmdomain.o dlmdebug.o dlmthread.o dlmrecovery.o \ dlmmaster.o dlmast.o dlmconvert.o dlmlock.o dlmunlock.o dlmver.o + +ocfs2_dlmfs-objs := userdlm.o dlmfs.o dlmfsver.o diff --git a/fs/ocfs2/dlm/dlmfs.c b/fs/ocfs2/dlm/dlmfs.c new file mode 100644 index 00000000000..dd2d24dc25e --- /dev/null +++ b/fs/ocfs2/dlm/dlmfs.c @@ -0,0 +1,640 @@ +/* -*- mode: c; c-basic-offset: 8; -*- + * vim: noexpandtab sw=8 ts=8 sts=0: + * + * dlmfs.c + * + * Code which implements the kernel side of a minimal userspace + * interface to our DLM.

This patch series implements per packet access control via the extension of the Linux Security Modules (LSM) interface by hooks in the XFRM and pfkey subsystems that leverage IPSec security associations to label packets. Extensions to the SELinux LSM are included that leverage the patch for this purpose. This patch implements the changes necessary to the XFRM subsystem, pfkey interface, ipv4/ipv6, and xfrm_user interface to restrict a socket to use only authorized security associations (or no security association) to send/receive network packets. Patch purpose: The patch is designed to enable access control per packets based on the strongly authenticated IPSec security association. Such access controls augment the existing ones based on network interface and IP address. The former are very coarse-grained, and the latter can be spoofed. By using IPSec, the system can control access to remote hosts based on cryptographic keys generated using the IPSec mechanism. This enables access control on a per-machine basis or per-application if the remote machine is running the same mechanism and trusted to enforce the access control policy. Patch design approach: The overall approach is that policy (xfrm_policy) entries set by user-level programs (e.g., setkey for ipsec-tools) are extended with a security context that is used at policy selection time in the XFRM subsystem to restrict the sockets that can send/receive packets via security associations (xfrm_states) that are built from those policies. A presentation available at www.selinux-symposium.org/2005/presentations/session2/2-3-jaeger.pdf from the SELinux symposium describes the overall approach. Patch implementation details: On output, the policy retrieved (via xfrm_policy_lookup or xfrm_sk_policy_lookup) must be authorized for the security context of the socket and the same security context is required for resultant security association (retrieved or negotiated via racoon in ipsec-tools). This is enforced in xfrm_state_find. On input, the policy retrieved must also be authorized for the socket (at __xfrm_policy_check), and the security context of the policy must also match the security association being used. The patch has virtually no impact on packets that do not use IPSec. The existing Netfilter (outgoing) and LSM rcv_skb hooks are used as before. Also, if IPSec is used without security contexts, the impact is minimal. The LSM must allow such policies to be selected for the combination of socket and remote machine, but subsequent IPSec processing proceeds as in the original case. Testing: The pfkey interface is tested using the ipsec-tools. ipsec-tools have been modified (a separate ipsec-tools patch is available for version 0.5) that supports assignment of xfrm_policy entries and security associations with security contexts via setkey and the negotiation using the security contexts via racoon. The xfrm_user interface is tested via ad hoc programs that set security contexts. These programs are also available from me, and contain programs for setting, getting, and deleting policy for testing this interface. Testing of sa functions was done by tracing kernel behavior.

This patch series implements per packet access control via the extension of the Linux Security Modules (LSM) interface by hooks in the XFRM and pfkey subsystems that leverage IPSec security associations to label packets. Extensions to the SELinux LSM are included that leverage the patch for this purpose. This patch implements the changes necessary to the SELinux LSM to create, deallocate, and use security contexts for policies (xfrm_policy) and security associations (xfrm_state) that enable control of a socket's ability to send and receive packets. Patch purpose: The patch is designed to enable the SELinux LSM to implement access control on individual packets based on the strongly authenticated IPSec security association. Such access controls augment the existing ones in SELinux based on network interface and IP address. The former are very coarse-grained, and the latter can be spoofed. By using IPSec, the SELinux can control access to remote hosts based on cryptographic keys generated using the IPSec mechanism. This enables access control on a per-machine basis or per-application if the remote machine is running the same mechanism and trusted to enforce the access control policy. Patch design approach: The patch's main function is to authorize a socket's access to a IPSec policy based on their security contexts. Since the communication is implemented by a security association, the patch ensures that the security association's negotiated and used have the same security context. The patch enables allocation and deallocation of such security contexts for policies and security associations. It also enables copying of the security context when policies are cloned. Lastly, the patch ensures that packets that are sent without using a IPSec security assocation with a security context are allowed to be sent in that manner. A presentation available at www.selinux-symposium.org/2005/presentations/session2/2-3-jaeger.pdf from the SELinux symposium describes the overall approach. Patch implementation details: The function which authorizes a socket to perform a requested operation (send/receive) on a IPSec policy (xfrm_policy) is selinux_xfrm_policy_lookup. The Netfilter and rcv_skb hooks ensure that if a IPSec SA with a securit y association has not been used, then the socket is allowed to send or receive the packet, respectively. The patch implements SELinux function for allocating security contexts when policies (xfrm_policy) are created via the pfkey or xfrm_user interfaces via selinux_xfrm_policy_alloc. When a security association is built, SELinux allocates the security context designated by the XFRM subsystem which is based on that of the authorized policy via selinux_xfrm_state_alloc. When a xfrm_policy is cloned, the security context of that policy, if any, is copied to the clone via selinux_xfrm_policy_clone. When a xfrm_policy or xfrm_state is freed, its security context, if any is also freed at selinux_xfrm_policy_free or selinux_xfrm_state_free. Testing: The SELinux authorization function is tested using ipsec-tools. We created policies and security associations with particular security contexts and added SELinux access control policy entries to verify the authorization decision. We also made sure that packets for which no security context was supplied (which either did or did not use security associations) were authorized using an unlabelled context.

-- GitLab From 318360646941d6f3d4c6e4ee99107392728a4079 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 13 Dec 2005 23:13:48 -0800 Subject: [PATCH 0659/2756] [NETFILTER] ip_tables: NUMA-aware allocation Part of a performance problem with ip_tables is that memory allocation is not NUMA aware, but 'only' SMP aware (ie each CPU normally touch separate cache lines) Even with small iptables rules, the cost of this misplacement can be high on common workloads. Instead of using one vmalloc() area (located in the node of the iptables process), we now allocate an area for each possible CPU, using vmalloc_node() so that memory should be allocated in the CPU's node if possible.

(The original patch is here: http://marc.theaimsgroup.com/?l=linux-netdev&m=112281936522415&w=2 and my only contribution is to have tested it.) This patch (optionally) does additional checks before accepting IP fragments, which can greatly reduce the possibility of reassembling fragments which originated from different IP datagrams.

This means that when we detect a checksum error we have to be careful when trying to free the packet as someone could have dequeued it in the time being. Currently this delicate logic is duplicated three times between UDPv4, UDPv6 and RAWv6. This patch moves them into a one place and simplifies the code somewhat.

(default linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at least) This patch makes sure a 'struct proto_ops' can be declared as const, so that all cpus can share all parts of it without false sharing. This is not mandatory : a driver can still use a read/write structure if it needs to (and eventually a __read_mostly) I made a global stubstitute to change all existing occurences to make them const. This should reduce the possibility of false sharing on SMP, and speedup some socket system calls. Signed-off-by: Eric Dumazet Signed-off-by: David S.

This causes them to be placed in .data instead of .bss. This patch de-initialises 3 static variables in net/core/pktgen.c. There are approximately 800 more such variables in the source tree (2.6.15rc5). If there is more interrest I'd be willing to track down the rest of these as well and de-initialise them as well.

Fix this by using a pointer to refer to skb_shared_info. By initializing skb_shared_info sequentially, the write combining buffers can reduce the number of memory transactions to a single write. Reorder the initialization in __alloc_skb() to match the structure definition. There is also an alignment issue on 64 bit systems with skb_shared_info by converting nr_frags to a short everything packs up nicely. Also, pass the slab cache pointer according to the fclone flag instead of using two almost identical function calls. This raises bw_unix performance up to a peak of 707KB/s when combined with the spinlock patch. It should help other networking protocols, too. Signed-off-by: David S.

From: Roberto Nibali The attached patch (against current -GIT) is a cleanup patch which does following: o lookup debug messages shifted back to 9 o added more informational value to flags and refcnt since those entries can be in multiple referenced structures o cleanup 80 char violation It's the prepatch to the session pool implementation and helps very much to debug and monitor important variables and structures regarding the threshold limitation and persistency without the thousands of lookup messages which noone is interested in.

When packets are received, the connection is either in DCCP_OPEN [fast-path] or it isn't. If it's not [e.g. DCCP_PARTOPEN] upper layers will perform sanity checks and parse options. If it is in DCCP_OPEN, dccp_rcv_established() will do it. It is important not to re-parse options in dccp_rcv_established() when it is not called from the fast-path. Else, fore example, the ack vector will be added twice and the CCID will see the packet twice. The solution is to always enfore sanity checks from the upper layers. When packets arrive in the fast-path, sanity checks will be performed before calling dccp_rcv_established(). Note(acme): I rewrote the patch to achieve the same result but keeping dccp_rcv_established with the previous semantics and having it split into __dccp_rcv_established, that doesn't does do any sanity check, code in state != DCCP_OPEN use this lighter version as they already do the sanity checks.

[ARM] 3192/1: Remove gpio_isr_line_clear() API from IXP4xx Patch from Deepak Saxena Other than interrupt masking purposes, this API is only used when configuring interrupt lines and this patch moves that functionality directly into the ixp4xx_set_irq_type() implementation as board level PCI code should not need to worry about those details.

The NAS100D is a consumer device containing a 266MHz Intel IXP420 processor, 16MB of flash, 64MB of RAM, a 160Gb internal IDE hard disk, and 802.11b/g wireless on an Atheros mini-PCI card. Work on porting the latest 2.6.x kernel to this device is being done by the NSLU2-Linux project (the same team who maintains the port to the Linksys NSLU2 device). In particular, the majority of this patch was authored by Alessandro Zummo, based on the work done for MACH_NSLU2 support by the NSLU2-Linux core team of developers. MACH_NAS100D (as implemented by this patch) can be enabled in jumbo ixp4xx kernels without any affect on the other machines supported by that kernel. This patch applies cleanly against 2.6.15-rc7 and should be trivial to apply to later kernel versions. It does not depend upon any other patches.

This patch, generated against your Oct 26 git tree, adds that support. The patch is basically the same as the one tested by Ivan Kalatchev, who reported the problem, on 2.6.13. Please apply, Support reinitializing the isp116x host controller from scratch on resume, if the controller has lost its state.

Most of the volume of the patch comes from 2 sources: moving the code around to get rid of a few function prototypes and reworking register dumping functions/macros. Among other things, switched over from using procfs to debugfs. Cleanup. The following changes were made: - Rework register dumping code so it can be used for dumping to both syslog and debugfs. - Switch from procfs to debugfs.. - Die gracefully on Unrecoverable Error interrupt. - Fix memory leak in isp116x_urb_enqueue(), if HC happens to die in a narrow time window. - Fix a 'sparce' warning (unnecessary cast). - Report Devices Removable for root hub ports by default (was Devices Permanently Attached). - Move bus suspend/resume functions down in code to get rid of a few function prototypes. - A number of one-line cleanups. - Add an entry to MAINTAINERS.

(In fact it does this even for non-control URBs, which is an additional aspect of the same bug.) However, under certain circumstances it's possible for transfer_dma to be 0 while transfer_buffer_length is non-zero. This can happen when a freshly allocated page (mapped to address 0 and marked Copy-On-Write, but never written to) is used as the source buffer for an OUT transfer. This patch (as598) fixes the problem.

The managing part was taken from bsd ueagle driver, other parts were written from scratch. The driver uses the in-kernel firmware loader : - to load a first usb firmware when the modem is in pre-firmware state - to load the dsp firmware that are swapped in host memory. - to load CMV (configuration and management variables) when the modem boot. (We can't use options or sysfs for this as there many possible values. See https://mail.gna.org/public/eagleusb-dev/2005-04/msg00031.html for a description of some) - to load fpga code for 930 chipset. The device had 4 endpoints : * 2 for data (use by usbatm). The incoming endpoint could be iso or bulk. The modem seems buggy and produce lot's of atm errors when using it in bulk mode for speed > 3Mbps, so iso endpoint is need for speed > 3Mbps. At the moment iso endpoint need a patched usbatm library and for this reason is not included in this patch. * One bulk endpoint for uploading dsp firmware * One irq endpoint that notices the driver - if we need to upload a page of the dsp firmware - an ack for read or write CMV and the value (for the read case). If order to make the driver cleaner, we design synchronous (read|write)_cmv : -send a synchronous control message to the modem -wait for an ack or a timeout -return the value if needed. In order to run these synchronous usb messages we need a kernel thread. The driver has been tested with sagem fast 800 modems with different eagle chipset revision and with ADI 930 since April 2005.

The existing code was wrong anyway; having a PCI PM capability doesn't imply it reports PME# is supported. I skimmed Intel's ICH7 datasheet and that basically says the wakeup signaling gets routed only through ACPI registers. (On the other hand, many VIA chips provide the PCI PM capabilities...) I think that doing this correctly with UHCI is going to require the ACPI folk to associate the /proc/acpi/wakeup identifiers (and wakeup enable/disable flags) with the relevant /sys/devices/pci*/... devices.

Example: echo 0557 2008 > /sys/bus/usb/drivers/foo_driver/new_id adds the hex values 0557 and 2008 to the device id table for the foo_driver. Note, usb-serial drivers do not currently work with this capability yet. usb-storage also might have some oddities.

The changes are confined to the core, except that the usb_trylock_device routine now uses the return convention of down_trylock rather than down_read_trylock (they return opposite values for no good reason). A couple of other associated changes are included as well: Now that we aren't concerned about HCDs that avoid using the hcd glue layer, usb_disconnect no longer needs to acquire the usb_bus_lock -- that can be done by usb_remove_hcd where it belongs. Devices aren't locked over the same scope of code in usb_new_device and hub_port_connect_change as they used to be. This shouldn't cause any trouble. Along with the preceding driver core patch, this needs a lot of testing.

Thanks to the changes in the driver core locking, we now know that the entire hub device (and not just the interface) is locked whenever the hub driver's disconnect method runs. Hence it is safe to disconnect the child device structures immediately instead of deferring the job. The earlier version of the patch neglected to disable the hub's ports. We don't want to forget that; otherwise we'd end up with live devices using addresses that have been recycled. This update adds the necessary code.

(This is something we should have been doing all along.) A new field in struct usb_device holds the amount of bus current available from the upstream port, and the usb_hub structure keeps track of the current available for each downstream port. Two new rules for configuration selection are added: Don't select a self-powered configuration when only bus power is available. Don't select a configuration requiring more bus power than is available. However the first rule is #if-ed out, because I found that the internal hub in my HP USB keyboard claims that its only configuration is self-powered. The rule would prevent the configuration from being chosen, leaving the hub & keyboard unconfigured. Since similar descriptor errors may turn out to be fairly common, it seemed wise not to include a rule that would break automatic configuration unnecessarily for such devices. The second rule may also trigger unnecessarily, although this should be less common. More likely it will annoy people by sometimes failing to accept configurations that should never have been chosen in the first place. The patch also changes usbcore's reaction when no configuration is suitable. Instead of raising an error and rejecting the device, now the core will simply leave the device unconfigured. People can always work around such problems by installing configurations manually through sysfs.

There is a race-condition in usb-serial driver that can be triggered if a processes does 'port->tty->driver_data = NULL' in serial_close() while other processes is in kernel-space about to call serial_ioctl() on the same port. This happens because a process can open the device while there is another one closing it. The patch below fixes that by adding a semaphore to ensure that no process will open the device while another process is closing it. Note that we can't use spinlocks here, since serial_open() and serial_close() can sleep.

This driver was written by Daniel Drake -- he notes that he wrote this driver without specs, however a vendor-supplied GPL driver for the previous generation of products ("sma03") did prove to be quite useful, as did the sddr09 driver which also has to deal with low-level physical block layout on SmartMedia. The original patch has been reformed by me, as it clashed with the libusual patches. We really need to consolidate some of this common SmartMedia code, and get together with the MTD guys to share it with them as well.

I used __module_param_call() instead of module_param because I wanted to preserve the old syntax in grub.conf, and it's the only macro which allows to remove the prefix.

I am quite surprised that nobody else noticed this before. Linus has a G5. Hackers hate printing in general, maybe. We do not use BKL anymore, because one of code paths had a sleeping call, so we had to use a semaphore. I am sure it's safe to use unlocked_ioctl. The new ioctls return long and retval is int. It looks completely fine to me. We never want these extra bits, and the sign extension ought to work right.

Only during early boot and in initramfs, /sbin/hotplug is needed. So merge the two functions and provide only one interface without all the options. The netlink layer got a nice generic interface with named slots recently, which is probably a better facility to plug events for subsystem specific events. Also the new poll() interface to /proc/mounts is a nicer way to notify about changes than sending events through the core. The uevents should only be used for driver core related requests to userspace now.

This facility is needed by USB device drivers, owing to the peculiar way USB devices work: A device provides multiple interfaces, and drivers are bound to interfaces rather than to devices; Nevertheless a reset, reset-configuration, suspend, or resume affects the entire device and requires the caller to hold the lock for the device, not just a lock for one of the interfaces. Since a USB driver's probe method is always called with the interface lock held, the locking order rules (always lock parent before child) prevent these methods from acquiring the device lock. The solution provided here is to call all probe and remove methods, for all devices (not just USB), with the parent lock already acquired. Although currently only the USB subsystem requires these changes, people have mentioned in prior discussion that the overhead of acquiring an extra semaphore in all the prove/remove sequences is not overly large. Up to now, the USB core has been using its own set of private semaphores. A followup patch will remove them, relying entirely on the device semaphores provided by the driver core. The code paths affected by this patch are: device_add and device_del: The USB core already holds the parent lock, so no actual change is needed. driver_register and driver_unregister: The driver core will now lock both the parent and the device before probing or removing. driver_bind and driver_unbind (in sysfs): These routines will now lock both the parent and the device before binding or unbinding. bus_rescan_devices: The helper routine will lock the parent before probing a device. I have not tested this patch for conflicts with other subsystems. As far as I can see, the only possibility of conflict would lie in the bus_rescan_devices pathway, and it seems pretty remote. Nevertheless, it would be good for this to get a lot of testing in -mm.

If they are called with a valid start object then klist_next will decrement the ref-count for the start object but nobody has incremented it.

IDE: MODALIAS support for autoloading of ide-cd, ide-disk, ... Add MODULE_ALIAS to IDE midlayer modules: ide-disk, ide-cd, ide-floppy and ide-tape, to autoload these modules depending on the probed media type of the IDE device. It is used by udev and replaces the former agent shell script of the hotplug package, which was required to lookup the media type in the proc filesystem. Using proc was racy, cause the media file is created after the hotplug event is sent out. The module autoloading does not take any effect, until something like the following udev rule is configured: SUBSYSTEM=="ide", ACTION=="add", ENV{MODALIAS}=="?*", RUN+="/sbin/modprobe $env{MODALIAS}" The module ide-scsi will not be autoloaded, cause it requires manual configuration. It can't be, and never was supported for automatic setup in the hotplug package. Adding a MODULE_ALIAS to ide-scsi for all supported media types, would just lead to a default blacklist entry anyway. $ modinfo ide-disk filename: /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko description: ATA DISK Driver alias: ide:*m-disk* license: GPL ... $ modprobe -vn ide:m-disk insmod /lib/modules/2.6.15-rc4-g1b0997f5/kernel/drivers/ide/ide-disk.ko $ cat /sys/bus/ide/devices/0.0/modalias ide:m-disk It also adds attributes to the IDE device: $ tree /sys/bus/ide/devices/0.0/ /sys/bus/ide/devices/0.0/ |-- bus -> ../../../../../../../bus/ide |-- drivename |-- media |-- modalias |-- power | |-- state | `-- wakeup `-- uevent $ cat /sys/bus/ide/devices/0.0/{modalias,drivename,media} ide:m-disk hda disk Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman --- drivers/ide/ide-cd.c | 1 + drivers/ide/ide-disk.c | 1 + drivers/ide/ide-floppy.c | 1 + drivers/ide/ide-tape.c | 1 + drivers/ide/ide.c | 60 ++++++++++++++++++++++++++++++++++++++++ 5 files changed, 64 insertions(+) diff --git a/drivers/ide/ide-cd.c b/drivers/ide/ide-cd.c index b4d7a3efb90..70aeb3a6012 100644 --- a/drivers/ide/ide-cd.c +++ b/drivers/ide/ide-cd.c @@ -3509,6 +3509,7 @@ static int __init ide_cdrom_init(void) return driver_register(&ide_cdrom_driver.gen_driver); } +MODULE_ALIAS("ide:*m-cdrom*"); module_init(ide_cdrom_init); module_exit(ide_cdrom_exit); MODULE_LICENSE("GPL"); diff --git a/drivers/ide/ide-disk.c b/drivers/ide/ide-disk.c index 449522f0540..4e5767968d7 100644 --- a/drivers/ide/ide-disk.c +++ b/drivers/ide/ide-disk.c @@ -1271,6 +1271,7 @@ static int __init idedisk_init(void) return driver_register(&idedisk_driver.gen_driver); } +MODULE_ALIAS("ide:*m-disk*"); module_init(idedisk_init); module_exit(idedisk_exit); MODULE_LICENSE("GPL"); diff --git a/drivers/ide/ide-floppy.c b/drivers/ide/ide-floppy.c index 9e293c8063d..fba3fffc2d6 100644 --- a/drivers/ide/ide-floppy.c +++ b/drivers/ide/ide-floppy.c @@ -2197,6 +2197,7 @@ static int __init idefloppy_init(void) return driver_register(&idefloppy_driver.gen_driver); } +MODULE_ALIAS("ide:*m-floppy*"); module_init(idefloppy_init); module_exit(idefloppy_exit); MODULE_LICENSE("GPL"); diff --git a/drivers/ide/ide-tape.c b/drivers/ide/ide-tape.c index 7d7944ed415..fab9b2b0250 100644 --- a/drivers/ide/ide-tape.c +++ b/drivers/ide/ide-tape.c @@ -4947,6 +4947,7 @@ out: return error; } +MODULE_ALIAS("ide:*m-tape*"); module_init(idetape_init); module_exit(idetape_exit); MODULE_ALIAS_CHARDEV_MAJOR(IDETAPE_MAJOR); diff --git a/drivers/ide/ide.c b/drivers/ide/ide.c index 8af179b531c..4b524f6b3ec 100644 --- a/drivers/ide/ide.c +++ b/drivers/ide/ide.c @@ -1904,9 +1904,69 @@ static int ide_bus_match(struct device *dev, struct device_driver *drv) return 1; } +static char *media_string(ide_drive_t *drive) +{ + switch (drive->media) { + case ide_disk: + return "disk"; + case ide_cdrom: + return "cdrom"; + case ide_tape: + return "tape"; + case ide_floppy: + return "floppy"; + default: + return "UNKNOWN"; + } +} + +static ssize_t media_show(struct device *dev, struct device_attribute *attr, char *buf) +{ + ide_drive_t *drive = to_ide_device(dev); + return sprintf(buf, "%s\n", media_string(drive)); +} + +static ssize_t drivename_show(struct device *dev, struct device_attribute *attr, char *buf) +{ + ide_drive_t *drive = to_ide_device(dev); + return sprintf(buf, "%s\n", drive->name); +} + +static ssize_t modalias_show(struct device *dev, struct device_attribute *attr, char *buf) +{ + ide_drive_t *drive = to_ide_device(dev); + return sprintf(buf, "ide:m-%s\n", media_string(drive)); +} + +static struct device_attribute ide_dev_attrs[] = { + __ATTR_RO(media), + __ATTR_RO(drivename), + __ATTR_RO(modalias), + __ATTR_NULL +}; + +static int ide_uevent(struct device *dev, char **envp, int num_envp, + char *buffer, int buffer_size) +{ + ide_drive_t *drive = to_ide_device(dev); + int i = 0; + int length = 0; + + add_uevent_var(envp, num_envp, &i, buffer, buffer_size, &length, + "MEDIA=%s", media_string(drive)); + add_uevent_var(envp, num_envp, &i, buffer, buffer_size, &length, + "DRIVENAME=%s", drive->name); + add_uevent_var(envp, num_envp, &i, buffer, buffer_size, &length, + "MODALIAS=ide:m-%s", media_string(drive)); + envp[i] = NULL; + return 0; +} + struct bus_type ide_bus_type = { .name = "ide", .match = ide_bus_match, + .uevent = ide_uevent, + .dev_attrs = ide_dev_attrs, .suspend = generic_ide_suspend, .resume = generic_ide_resume, }; -- GitLab From 1d8f430c15b3a345db990e285742c67c2f52f9a6 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 7 Dec 2005 21:40:34 +0100 Subject: [PATCH 0862/2756] [PATCH] Input: add modalias support Here's the patch for modalias support for input classes. It uses comma-separated numbers, and doesn't describe all the potential keys (no module currently cares, and that would make the strings huge). The changes to input.h are to move the definitions needed by file2alias outside __KERNEL__. I chose not to move those definitions to mod_devicetable.h, because there are so many that it might break compile of something else in the kernel. The rest is fairly straightforward.

The CF reset code was resetting this register leading to various lockups as the MMC power was suddenly lost. This patch handles the CPR register in a more sensitive manner. It also removes some unneeded collie specific calls as the reset code handles this.

Because of this, we cannot hardcode the physical base as we currently do. This patch checks the expansion bus configuration registers at runtime to determine the appropriate window size. Note that this requires that the bootloader already configured the device sizes appropriately, but I feel that is valid assumption to make as the bootloader must configure and access the flash window, the output display (LCD, LEDs, etc) window, and other expansion bus devices.

Ortiz" Date: Thu, 5 Jan 2006 13:12:41 -0800 Subject: [PATCH 0904/2756] [ATYFB]: Fix onboard video on SPARC Blade 100 for 2.6.{13,14,15} I have recently been switching from using 2.4.32 on my trusty old Sparc Blade 100 to using 2.6.15 . Some of the problems I ran into were distorted video when the console was active (missing first character, skipped dots) and when running X windows (colored snow, stripes, missing pixels). A quick examination of the 2.6 versus 2.4 source for the ATY driver revealed alot of changes. A closer look at the code/data for the 64GR/XL chip revealed two minor "typos" that the rewriter(s) of the code made. The first is a incorrect clock value (230 .vs. 235) and the second is a missing flag (M64F_SDRAM_MAGIC_PLL). Making both these changes seems to have fixed my problem. I tend to think the 235 value is the correct one, as there is a 29.4 Mhz clock crystal close to the video chip and 235.2 (29.4*8) is too close to 235 to make it a coincidence. The flag for M64F_SDRAM_MAGIC_PLL was dropped during the changes made by adaplas in file revision 1.72 on the old bitkeeper repository. The change relating to the clock rate has been there forever, at least in the 2.6 tree. I'm not sure where to look for the old 2.5 tree or if anyone cares when it happened. On SPARC Blades 100's, which use the ATY MACH64GR video chipset, the clock crystal frequency is 235.2 Mhz, not 230 Mhz. The chipset also requires the use of M64F_SDRAM_MAGIC_PLL in order to setup the PLL properly for the DRAM. Signed-off-by: Luis F. Ortiz Signed-off-by: David S.

As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski --- Documentation/pcmcia/driver-changes.txt | 6 +- drivers/bluetooth/bluecard_cs.c | 46 ++---- drivers/bluetooth/bt3c_cs.c | 45 ++---- drivers/bluetooth/btuart_cs.c | 46 ++---- drivers/bluetooth/dtl1_cs.c | 45 ++---- drivers/char/pcmcia/cm4000_cs.c | 68 ++------- drivers/char/pcmcia/cm4040_cs.c | 67 ++------- drivers/char/pcmcia/synclink_cs.c | 49 ++----- drivers/ide/legacy/ide-cs.c | 56 ++------ drivers/isdn/hardware/avm/avm_cs.c | 56 ++------ drivers/isdn/hisax/avma1_cs.c | 70 ++-------- drivers/isdn/hisax/elsa_cs.c | 78 ++--------- drivers/isdn/hisax/sedlbauer_cs.c | 75 ++-------- drivers/isdn/hisax/teles_cs.c | 67 ++------- drivers/mtd/maps/pcmciamtd.c | 54 ++------ drivers/net/pcmcia/3c574_cs.c | 55 ++------ drivers/net/pcmcia/3c589_cs.c | 63 ++------- drivers/net/pcmcia/axnet_cs.c | 59 ++------ drivers/net/pcmcia/com20020_cs.c | 59 ++------ drivers/net/pcmcia/fmvj18x_cs.c | 54 ++------ drivers/net/pcmcia/ibmtr_cs.c | 69 ++------- drivers/net/pcmcia/nmclan_cs.c | 57 ++------ drivers/net/pcmcia/pcnet_cs.c | 45 ++---- drivers/net/pcmcia/smc91c92_cs.c | 57 ++------ drivers/net/pcmcia/xirc2ps_cs.c | 67 ++------- drivers/net/wireless/airo_cs.c | 74 ++-------- drivers/net/wireless/atmel_cs.c | 80 +++-------- drivers/net/wireless/hostap/hostap_cs.c | 55 ++------ drivers/net/wireless/netwave_cs.c | 68 ++------- drivers/net/wireless/orinoco_cs.c | 58 ++------ drivers/net/wireless/ray_cs.c | 68 ++------- drivers/net/wireless/spectrum_cs.c | 63 ++------- drivers/net/wireless/wavelan_cs.c | 84 ++--------- drivers/net/wireless/wavelan_cs.p.h | 8 -- drivers/net/wireless/wl3501_cs.c | 60 ++------ drivers/parport/parport_cs.c | 61 ++------ drivers/pcmcia/ds.c | 177 ++++-------------------- drivers/scsi/pcmcia/aha152x_stub.c | 52 ++----- drivers/scsi/pcmcia/fdomain_stub.c | 56 ++------ drivers/scsi/pcmcia/nsp_cs.c | 67 ++------- drivers/scsi/pcmcia/nsp_cs.h | 2 - drivers/scsi/pcmcia/qlogic_stub.c | 49 ++----- drivers/scsi/pcmcia/sym53c500_cs.c | 53 ++----- drivers/serial/serial_cs.c | 58 ++------ drivers/telephony/ixj_pcmcia.c | 48 ++----- drivers/usb/host/sl811_cs.c | 44 ++---- include/pcmcia/cs.h | 1 - include/pcmcia/ds.h | 6 +- 48 files changed, 472 insertions(+), 2233 deletions(-) diff --git a/Documentation/pcmcia/driver-changes.txt b/Documentation/pcmcia/driver-changes.txt index 45c25c7a344..97420f08c78 100644 --- a/Documentation/pcmcia/driver-changes.txt +++ b/Documentation/pcmcia/driver-changes.txt @@ -1,7 +1,9 @@ This file details changes in 2.6 which affect PCMCIA card driver authors: -* Unify detach and REMOVAL event code (as of 2.6.16) - void (*remove) (struct pcmcia_device *dev);

Using the "nonstatic" socket library is inpractical for them, as they do neither need a resource database (as we can trust the kernel resource database on m68k and ppc) nor lots of other features of that library. Let them get a small "iodyn" socket library (105 lines of code) instead.

If any driver really doesn't want to be notified when i2c adapters are added, that driver can simply omit to set .attach_adapter. This approach is also more robust as it prevents accidental NULL pointer dereferences.

This change makes the following behavior changes. * Partial completion of the barrier request is handled as failure of the whole ordered sequence. No more partial completion for barrier requests. * Any failure of pre or post flush request results in failure of the whole ordered sequence. So, successfully completed ordered sequence guarantees that all requests prior to the barrier made to physical medium and, then, the while barrier request made to the physical medium.

With his help, this was tracked down to bogus bio vectors which in turn was the result of a race condition between the receive/transmit routines in the NBD driver. The bug manifests itself like this: CPU0 CPU1 do_nbd_request add req to queuelist nbd_send_request send req head for each bio kmap send nbd_read_stat nbd_find_request nbd_end_request kunmap When CPU1 finishes nbd_end_request, the request and all its associated bio's are freed. So when CPU0 calls kunmap whose argument is derived from the last bio, it may crash. Under normal circumstances, the race occurs only on the last bio. However, if an error is encountered on the remote NBD server (such as an incorrect magic number in the request), or if there were a bug in the server, it is possible for the nbd_end_request to occur any time after the request's addition to the queuelist. The following patch fixes this problem by making sure that requests are not added to the queuelist until after they have been completed transmission. In order for the receiving side to be ready for responses involving requests still being transmitted, the patch introduces the concept of the active request. When a response matches the current active request, its processing is delayed until after the tranmission has come to a stop. This has been tested by Janos and it has been successful in curing this race condition. From: Herbert Xu Here is an updated patch which removes the active_req wait in nbd_clear_queue and the associated memory barrier. I've also clarified this in the comment.

The hash.h hash_long function, when used on a 64 bit machine, ignores many of the middle-order bits. (The prime chosen it too bit-sparse). IP addresses for clients of an NFS server are very likely to differ only in the low-order bits. As addresses are stored in network-byte-order, these bits become middle-order bits in a little-endian 64bit 'long', and so do not contribute to the hash. Thus you can have the situation where all clients appear on one hash chain. So, until hash_long is fixed (or maybe forever), us a hash function that works well on IP addresses - xor the bytes together. Thanks to "Iozone" for identifying this problem.

Reiser4 needs truncate_inode_pages_ranges because it tries to keep correspondence between existences of metadata pointing to data pages and pages to which those metadata point to. So, when metadata of certain part of file is removed from filesystem tree, only pages of corresponding range are to be truncated.

Current implementation supports only shmfs/tmpfs and other filesystems return -ENOSYS. "Some app allocates large tmpfs files, then when some task quits and some client disconnect, some memory can be released. However the only way to release tmpfs-swap is to MADV_REMOVE". - Andrea Arcangeli Databases want to use this feature to drop a section of their bufferpool (shared memory segments) - without writing back to disk/swap space. This feature is also useful for supporting hot-plug memory on UML. Concerns raised by Andrew Morton: - "We have no plan for holepunching! If we _do_ have such a plan (or might in the future) then what would the API look like? I think sys_holepunch(fd, start, len), so we should start out with that." - Using madvise is very weird, because people will ask "why do I need to mmap my file before I can stick a hole in it?" - None of the other madvise operations call into the filesystem in this manner. A broad question is: is this capability an MM operation or a filesytem operation? truncate, for example, is a filesystem operation which sometimes has MM side-effects. madvise is an mm operation and with this patch, it gains FS side-effects, only they're really, really significant ones." Comments: - Andrea suggested the fs operation too but then it's more efficient to have it as a mm operation with fs side effects, because they don't immediatly know fd and physical offset of the range. It's possible to fixup in userland and to use the fs operation but it's more expensive, the vmas are already in the kernel and we can use them. Short term plan & Future Direction: - We seem to need this interface only for shmfs/tmpfs files in the short term. We have to add hooks into the filesystem for correctness and completeness. This is what this patch does. - In the future, plan is to support both fs and mmap apis also. This also involves (other) filesystem specific functions to be implemented. - Current patch doesn't support VM_NONLINEAR - which can be addressed in the future.

This helps us to safely use hugetlb pages in many more applications. The patch makes the following changes. If needed, I also have it broken out according to the following paragraphs. 1. Add a pair of functions to set/clear write access on huge ptes. The writable check in make_huge_pte is moved out to the caller for use by COW later. 2. Hugetlb copy-on-write requires special case handling in the following situations: - copy_hugetlb_page_range() - Copied pages must be write protected so a COW fault will be triggered (if necessary) if those pages are written to. - find_or_alloc_huge_page() - Only MAP_SHARED pages are added to the page cache. MAP_PRIVATE pages still need to be locked however. 3. Provide hugetlb_cow() and calls from hugetlb_fault() and hugetlb_no_page() which handles the COW fault by making the actual copy. 4. Remove the check in hugetlbfs_file_map() so that MAP_PRIVATE mmaps will be allowed. Make MAP_HUGETLB exempt from the depricated VM_RESERVED mapping check.

This will result in a placement of the huge pages near the executing processor improving performance. The existing implementation can place the huge pages far away from the executing processor causing significant degradation of performance. The search starting from zero also means that the lower zones quickly run out of memory. Selecting a huge page near the process distributed the huge pages better.

Two in linux/mmzone.h and one in asm/mmzone.h. These in essence represent the three memory models. The definition in linux/mmzone.h under !NEED_MULTIPLE_NODES is both the FLATMEM definition and the optimisation for single NUMA nodes; the one under SPARSEMEM is the NUMA sparsemem one; the one in asm/mmzone.h under DISCONTIGMEM is the discontigmem one. This is not in the least bit obvious, particularly the connection between the non-NUMA optimisations and the memory models. Two patches: flatmem-split-out-memory-model: simplifies the selection of pfn_to_nid() implementations. The selection is based primarily off the memory model selected. Optimisations for non-NUMA are applied where needed. sparse-provide-pfn_to_nid: implement pfn_to_nid() for SPARSEMEM This patch: pfn_to_nid is memory model specific The pfn_to_nid() call is memory model specific. It represents the locality identifier for the memory passed. Classically this would be a NUMA node, but not a chunk of memory under DISCONTIGMEM. The SPARSEMEM and FLATMEM memory model non-NUMA versions of pfn_to_nid() are folded together under NEED_MULTIPLE_NODES, while DISCONTIGMEM has its own optimisation. This is all very confusing. This patch splits out each implementation of pfn_to_nid() so that we can see them and the optimisations to each.

A new function, __free_pages_bootmem(), is provided in mm/page_alloc.c that is called from mm/bootmem.c to turn pages over to the main allocator. All the bits of code to initialise pages (clearing PG_reserved and setting the page count) are moved to here. The checks on page validity are removed, on the assumption that the struct page arrays will have been prepared correctly.

As find_lock_page() already checks with TestSetPageLocked() that page is locked, there is no need to call lock_page() that will try-lock page again (chances of page being unlocked in between are small). Call __lock_page() directly, this saves one atomic operation. Also, mark truncate-while-slept path as unlikely while we are here. (akpm: ug. But this is actually a common path for normal old read()s against a page which is under readahead I/O so ho-hum.)

The changelog for that patch was: The shrink_zone() logic can, under some circumstances, cause far too many pages to be reclaimed. Say, we're scanning at high priority and suddenly hit a large number of reclaimable pages on the LRU. Change things so we bale out when SWAP_CLUSTER_MAX pages have been reclaimed. Problem is, this change caused significant imbalance in inter-zone scan balancing by truncating scans of larger zones. Suppose, for example, ZONE_HIGHMEM is 10x the size of ZONE_NORMAL. The zone balancing algorithm would require that if we're scanning 100 pages of ZONE_HIGHMEM, we should scan 10 pages of ZONE_NORMAL. But this logic will cause the scanning of ZONE_HIGHMEM to bale out after only 32 pages are reclaimed. Thus effectively causing smaller zones to be scanned relatively harder than large ones. Now I need to remember what the workload was which caused me to write this patch originally, then fix it up in a different way...

This seems to be a bit strange. policy zone seems to not be initialized elsewhere and therefore 0. Do we police ZONE_DMA if no bind policy has been used yet? This patch moves the determination of the zone to apply policies to into the page allocator. We determine the zone while building the zonelist for nodes.

We have to do ugly ifdefs to fall back to 32 bit atomic on 32 bit platforms. The VM statistics patch that I am working on will also make more extensive use of atomic64. This patch introduces a new type atomic_long_t by providing definitions in asm-generic/atomic.h that works similar to the c "long" type. Its 32 bits on 32 bit platforms and 64 bits on 64 bit platforms. Also cleans up the determination of the mm_counter_t in sched.h.

The mapping may start anywhere and be of any size, but may not go over the end of file. Multiple mappings may overlap in any way. (3) Not permitting a file to be shrunk if it would truncate any shared mappings (private mappings are copied). Thus this patch provides support for POSIX shared memory on NOMMU kernels, with certain limitations such as there being a large enough block of pages available to support the allocation and it only working on directly mappable filesystems.

The following changes are made: (1) There are now shmem_mmap() and shmem_get_unmapped_area() functions to allow the IPC SHM facilities to commune with the tiny-shmem and shmem code. (2) ramfs files now need resizing using do_truncate() rather than by modifying the inode size directly (see shmem_file_setup()). This causes ramfs to attempt to bind a block of pages of sufficient size to the inode. (3) CONFIG_SYSVIPC is no longer contingent on CONFIG_MMU.

If this is not enabled, then we can assume that EFAULT returned from futex_atomic_op_inuser() is not recoverable, and that the address lies outside of valid memory. handle_mm_fault() is made to BUG if called on NOMMU without attempting to invoke the actual handler (__handle_mm_fault).

(2) After the signal frame is set up on the userspace stack, ptrace() should be given an opportunity to single-step into the signal handler. (3) The error state from setting up a signal frame should be passed back up the call chain. (4) The segfault handler shouldn't be preemptively reset in the arch if we fail to deliver a SEGV signal: force_sig() will take care of that.

From 7c4cb60e5b97677424e95baee9c29df54b26e6ba Mon Sep 17 00:00:00 2001 From: Zachary Amsden Date: Fri, 6 Jan 2006 00:11:47 -0800 Subject: [PATCH 1074/2756] [PATCH] x86: GDT alignment fix Make GDT page aligned and page padded to support running inside of a hypervisor. This prevents false sharing of the GDT page with other hot data, which is not allowed in Xen, and causes performance problems in VMware. Rather than go back to the old method of statically allocating the GDT (which wastes unneded space for non-present CPUs), the GDT for APs is allocated dynamically.

By default, APM_RELAX_SEGMENTS is always turned on to support running the APM BIOS on these buggy machines. Keeping 64k limits poses very little danger to the kernel, because the pages where the APM BIOS is located will always be in low physical memory BIOS areas, which should already be marked reserved, and only buggy BIOSes would possibly overstep the segment bounds with writes to data anyway. Since forcing stricter limits breaks many machines and is not default behavior, it seems reasonable to deprecate the older code which may cause APM BIOS to fault. If you really have a badly enough broken APM BIOS that you have to turn off APM_RELAX_SEGMENTS, seems like the best recourse here would be to disable the APM BIOS and / or not compile it into your kernel to begin with, and / or add your system to the known bad list. The reason I want to deprecate this code is there is underlying brokenness with the set_limit macros, and getting rid of many of the call sites rather than rewriting them seems to be the simplest and most correct course of action.

These parameteres may be passed from arbitrary kernel virtual memory, so they deserve strict protection to stop a bad BIOS from smashing beyond the object size. Unfortunately, the use of set_limit was badly botching this by setting the limit in terms of pages, when it really should have byte granularity. When doing this, I discovered my BIOS had the buggy code during the "get system device node" call: mov ax, es:[bx] Which is harmless, but has a trivial workaround.

Intel chipsets (at least) don't provide any architectural guarantee on what the chipset will do with this message. For example, the E850x chipsets uses this xTPR message to interpret the interrupt operating mode of the platform. When the CPU coming online sends this message, it always indicates that it is in logical flat mode. For the CPU hotplug case, the platform may already be functioning in cluster APIC mode at this time, the chipset can get confused and mishandle I/O device and IPI interrupt routing. The situation eventually gets corrected when the new CPU sends another xTPR update when we switch it to cluster mode, but there's a window during which the chipset may be in an inconsistent state. This patch avoids this problem by using the flat physical interrupt delivery mode instead of cluster mode for bigsmp (>8 cpu) support.

The same bug got fixed a while back on x86-64, but never got propagated to i386. Stuart Hayes from Dell also picked up on this last June, but it never got fixed, as the only thing affected by it aparently was the nvidia driver. Blatantly stealing description from his post.. "It doesn't appear to be fixed (in the i386 arch). The change_page_attr()/split_large_page() code will still still set all the 4K PTEs to PAGE_KERNEL (setting the _PAGE_NX bit) when a large page needs to be split. This wouldn't be a problem for the bulk of the kernel memory, but there are pages in the lower 4MB of memory that's free, and are part of large executable pages that also contain kernel code.

This enables getting timer interrupts in second kernel in legacy mode. o After putting into virtual wire mode, IOAPIC delivers the i8259 interrupts to CPU0. This works well for kexec but not for kdump as we might crash on a different CPU and second kernel will not see timer interrupts. o This patch modifies the redirection table entry to deliver the timer interrupts to the cpu we are rebooting (instead of hardcoding to zero). This ensures that second kernel receives timer interrupts even on a non-boot cpu.

Wysocki" Date: Fri, 6 Jan 2006 00:13:05 -0800 Subject: [PATCH 1114/2756] [PATCH] swsusp: introduce the swap map structure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch introduces the swap map structure that can be used by swsusp for keeping tracks of data pages written to the swap.  The structure itself is described in a comment within the patch. The overall idea is to reduce the amount of metadata written to the swap and to write and read the image pages sequentially, in a file-alike way. This makes the swap-handling part of swsusp fairly independent of its snapshot-handling part and will hopefully allow us to completely separate these two parts in the future. This patch is needed to remove the suspend image size limit imposed by the limited size of the swsusp_info structure, which is essential for x86-64 systems with more than 512 MB of RAM.

Wysocki" Date: Fri, 6 Jan 2006 00:13:46 -0800 Subject: [PATCH 1115/2756] [PATCH] swsusp: improve freeing of memory MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch makes swsusp free only as much memory as needed to complete the suspend and not as much as possible.  In the most of cases this should speed up the suspend and make the system much more responsive after resume, especially if a GUI (eg. X Windows) is used. If needed, the old behavior (ie to free as much memory as possible during suspend) can be restored by unsetting FAST_FREE in power.h Signed-off-by: Rafael J.

Wysocki" Date: Fri, 6 Jan 2006 00:14:20 -0800 Subject: [PATCH 1116/2756] [PATCH] swsusp: fix enough_free_mem This patch fixes a problem with the function enough_free_mem() used by swsusp to verify if there is a sufficient number of memory pages available to it to create and save the suspend image. Namely, enough_free_mem() uses nr_free_pages() to obtain the number of free memory pages, which is incorrect, because this function returns the total number of free pages, including free highmem pages, and the highmem pages cannot be used by swsusp for storing the image data. The patch makes enough_free_mem() avoid counting the free highmem pages as available to swsusp. Signed-off-by: Rafael J.

The main thing it does is to make swsusp_header contain the offset of the swap map used to track the image data pages rather than the offset of swsusp_info.  Simultaneously, swsusp_info becomes the first image page written to the swap. The other changes are generally consequences of the above with a few exceptions (there's some consolidation in the image reading part as a few functions turn into trivial wrappers around something else).

Some legacy MMU-less m32r chips cannot return from a trap handler to the right-hand side 16-bit halfword code of a 32-bit instrucion code pair, because a "trap" instruction specification was expanded in M32R-II ISA. This modification forces "trap" instructions to be placed in word alignment location with a parallel "nop" code.

The intent is to make it obvious that an IRQ can't exist without an open file descriptor. chan_enable will now open the channel, and when both opening and IRQ registration are desired, this should be used. Opening only is done for the initial console, so that interface still needs to exist. The free_irqs_later interface is now gone. It was intended to avoid freeing an IRQ while it was being processed. It did this, but it didn't eliminate the possiblity of free_irq being called from an interrupt, which is bad. In its place is a list of irqs to be freed, which is processed by the signal handler just before exiting. close_one_chan now disables irqs. When a host device disappears, it is just closed, and that disables IRQs. The device id registered with the IRQ is now the chan structure, not the tty. This is because the interrupt arrives on a descriptor associated with the channel. This caused equivalent changes in the arguments to line_timer_cb. line_disable is gone since it is not used any more. The count field in the line structure is gone. tty->count is used instead. The complicated logic in sigio_handler with freeing IRQs when necessary and making sure its idea of the next irq is correct is now much simpler. The irq list can't be rearranged underneath it, so it is now a simple list walk.

As it turns out, I moved most of it anyway. This patch is the minimal one needed to move the code and have it work. It turns out that the concept of the umid is OS-independent, but almost everything else about the implementation is OS-dependent. This is code movement without cleanup - a follow-on patch tidies everything up without shuffling code around.

This eliminates the practice of passing a pointer to printf or printk in, depending on where in the boot process we are. - Major tidying of not_dead_yet - mostly error path cleanup, plus a comment explaining why it doesn't react to errors the way you might expect. - Calls to os_* interfaces that were moved under os are changed back to their native libc forms. - snprintf, strlcpy, and their bounds-checking friends are used more often, replacing by-hand bounds checking in some places.

QDIO and HiperSockets processing in z/VM V=V guest environments (as well as V=R with z/VM running in LPAR mode) requires shadowing of all QDIO architecture queue elements. Especially the shadowing of SBALs and SLSBs structures in the hypervisor, and the need to issue SIGA SYNC operations to observe state changes, eventually causes significant CPU processing overhead in the hypervisor. The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and SLSBs. This significantly reduces the hypervisor overhead for QDIO based I/O.

Now let the lookup method return a zero node ID (not used for anything else) meaning a negative entry, but with a positive cache timeout. The old way of signaling negative entry (replying ENOENT) still works. Userspace should check the ABI minor version to see whether sending a zero ID is allowed by the kernel or not.

Also remove the fixed limit on setxattr data and let the filesystem provide as large a read buffer as it needs to handle the extended attribute data. The symbolic link length is already checked by VFS to be less than PATH_MAX, so the extra check against FUSE_SYMLINK_MAX is not needed. The check in fuse_create_open() against FUSE_NAME_MAX is not needed, since the dentry has already been looked up, and hence the name already checked.

This is something svc_recv isn't able to deal with: len = svsk->sk_recvfrom(rqstp); [...] if (len == 0 || len == -EAGAIN) { [...] return -EAGAIN; } [...] return len; The nfsd main loop will exit when it sees an error code other than EAGAIN. The following patch fixes this problem svc_recv is not equipped to deal with error codes other than EAGAIN, and will propagate anything else (such as ECONNRESET) up to nfsd, causing it to exit.

This as noticed when exporting directories using fuse. This patch cleans up most of the offences, which involves moving the call to vfs_getattr out of the xdr encoding routines (where it is too late to report an error) into the main NFS procedure handling routines. There is still a called to vfs_gettattr (related to the ACL code) where the status is ignored, and called to nfsd_sync_dir don't check return status either.

Looking at each of these, I see that nfsd_write (which includes nfsd_vfs_write) contributes 0x8c to stack usage itself!!

Wong" Date: Fri, 6 Jan 2006 00:20:11 -0800 Subject: [PATCH 1234/2756] [PATCH] make dm-mirror not issue invalid resync requests I've been attempting to set up a (Host)RAID mirror with dm_mirror on 2.6.14.3, and I've been having a strange little problem. The configuration in question is a set of 9GB SCSI disks that have 17942584 sectors. I set up the dm_mirror table as such: 0 17942528 mirror core 2 2048 nosync 2 8:48 0 8:64 0 If I'm not mistaken, this sets up a 9GB RAID1 mriror with 1MB stripes across both SCSI disks. The sector count of the dm device is less than the size of the disks, so we shouldn't fall off the end. However, I always get the messages like this in dmesg when I set up the dm table: attempt to access beyond end of device sdd: rw=0, want=17958656, limit=17942584 Clearly, something is trying to read sectors past the end of the drive. I traced it down to the __rh_recovery_prepare function in dm-raid1.c, which gets called when we're putting the mirror set together. This function calls the dirty region log's get_resync_work function to see if there's any resync that needs to be done, and queues up any areas that are out of sync. The log's get_resync_work function is actually a pointer to the core_get_resync_work function in dm-log.c. The core_get_resync_work function queries a bitset lc->sync_bits to find out if there are any regions that are out of date (i.e. the bit is 0), which is where the problem occurs. If every bit in lc->sync_bits is 1 (which is the case when we've just configured a new RAID1 with the nosync option), the find_next_zero_bit does NOT return the size parameter (lc->region_count in this case), it returns the size parameter rounded up to the nearest multiple of 32! I don't know if this is intentional, but i386 and x86_64 both exhibit this behavior. In any case, the statement "if (*region == lc->region_count)" looks like it's supposed to catch the case where are no regions to resync and return 0. Since find_next_zero_bit apparently has a habit of returning a value that's larger than lc->region_count, the enclosed patch changes the equality test to a greater-than test so that we don't try to resync areas outside of the RAID1 region. Seeing as the HostRAID metadata lives just past the end of the RAID1 data, mucking around in that area is not a good idea. I suppose another way to fix this would be to amend find_next_zero_bit so that it doesn't return values larger than "size", but I don't know if there's a reason for the current behavior.

Doing the check can reduce writes (often to 0) for a resync, and it is needed to properly implement the echo check > sync_action operation. This patch implements the appropriate checks and tidies up some related code. It also allows raid6 user-requested resync to bypass the intent bitmap.

A previous patch added support for read errors during normal IO. This one adds support for read errors during resync or recovery. The key differences are that we don't need to freeze the array, because the normal handling of resync means that this part of the array will be idle except for resync, and the read/overwrite/re-read is needed in a separate piece of code.

For the first two, get an rcu_readlock. For the last, the same access (md_sync_acct call) is made a little later after the rdev has been claimed under and rcu_readlock, if R5_Syncio is set. So just use that access... However R5_Syncio isn't really needed as the 'syncing' variable contains the same information. So use that instead.

When read-only, we don't over-write, so we need to mark the failed drive in the r10_bio so we don't re-try it. During resync, we always read all blocks, so if there is a read error, we simply over-write it with the good block that we found (assuming we found one). Note that the recovery case still isn't handled in an interesting way. There is nothing useful to do for the 2-copies case. If there are 3 or more copies, then we could try reading from one of the non-missing copies, but this is a bit complicated and very rarely would be used, so I'm leaving it for now.

It is similar to the poll-ability of /proc/mounts, though different in that: We always report that the file is readable (because face it, it is, even if only for EOF). We report POLLPRI when there is a change so that select() can detect it as an exceptional event. Not only are these exceptional events, but that is the mechanism that the current 'mdadm' uses to watch for events (It also polls after a timeout). (We also report POLLERR like /proc/mounts). Finally, we only reset the per-file event counter when the start of the file is read, rather than when poll() returns an event. This is more robust as it means that an fd will continue to report activity to poll/select until the program clearly responds to that activity. md_new_event takes an 'mddev' which isn't currently used, but it will be soon.

These personalities have fairly artificial 'numbers'. The numbers are use to: 1- provide an index into an array where the various personalities are recorded 2- identify the module (via an alias) which implements are particular personality. Neither of these uses really justify the existence of personality numbers. The array can be replaced by a linked list which is searched (array lookup only happens very rarely). Module identification can be done using an alias based on level rather than 'personality' number. The current 'raid5' modules support two level (4 and 5) but only one personality. This slight awkwardness (which was handled in the mapping from level to personality) can be better handled by allowing raid5 to register 2 personalities. With this change in place, the core md module does not need to have an exhaustive list of all possible personalities, so other personalities can be added independently. This patch also moves the check for chunksize being non-zero into the ->run routines for the personalities that need it, rather than having it in core-md. This has a side effect of allowing 'faulty' and 'linear' not to have a chunk-size set.

For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.

Module installation -- GitLab From 117a93db1dcd6ed61336b27e4e2938f791c1841b Mon Sep 17 00:00:00 2001 From: Rene Scharfe Date: Wed, 4 Jan 2006 20:42:03 +0100 Subject: [PATCH 1286/2756] kbuild: Use git in scripts/setlocalversion Currently scripts/setlocalversion is a Perl script that tries to figure out the current git commit ID of a repo without using git. It also imports Digest::MD5 without using it and generally is too big for the small task it does. :] And it always reports a git ID, even when the HEAD is tagged -- this is a bug. This patch replaces it with a Bourne Shell script that uses git commands to do the same. I can't come up with a scenario where someone would use a git repo and refuse to install git core at the same time, so I think it's reasonable to assume git is available. The new script also reports uncommitted changes by adding -git_dirty to the version string. Obviously you can't see from that _what_ has been changed from the last commit, so it's more of a reminder that you forgot to commit something. The script is easily extensible: simply add a check for Mercurial (or whatever) below the git check. Note: the script doesn't print a newline char anymore. That's only because it was easier to implement it that way, not a feature (or bug). 'make kernelrelease' doesn't care.

We may also need to schedule new work (including new RPC calls) in order to cancel the new state. The asynchronous RPC model will allow us to ensure that RPC calls always complete, but in order to allow for "synchronous" RPC, we want to add the ability to wait for completion. The waits are, of course, interruptible.

IOW: doing OPEN(O_RDWR) and then OPEN_DOWNGRADE(O_WRONLY) is forbidden unless the user called OPEN(O_WRONLY) In order to fix that, we really need to track the three possible open states separately.

The Solaris NFS server allows up to a megabyte, for instance. Now the Linux NFS client supports transfer sizes up to 1MB, too. This will help reduce protocol and context switch overhead on read/write intensive NFS workloads, and support larger atomic read and write operations on servers that support them. Test-plan: Connectathon and iozone on mount point with wsize=rsize>32768 over TCP. Tests with NFS over UDP to verify the maximum RPC payload size cap.

This is incorrect. The Open Group documentation says that "This procedure cancels an *outstanding* blocked lock request." (Emphasis mine.) Also, consider a client that holds a lock on the first byte of a file, and requests a lock on the entire file. If the client cancels that request (perhaps because the requesting process is signalled), the server shouldn't apply perform an unlock on the entire file, since that will also remove the previous lock that the client was already granted.

In the current IPv4 socket transport implementation, RPC buffers are allocated as needed for each RPC message that is sent. Some transport implementations may choose to use pre-allocated buffers for encoding, sending, receiving, and unmarshalling RPC messages, however. For transports capable of direct data placement, the buffers can be carved out of a pre-registered area of memory rather than from a slab cache. Test-plan: Millions of fsx operations. Performance characterization with "sio" and "iozone". Use oprofile and other tools to look for significant regression in CPU utilization.

Add some BUG_ON checks to catch cases where the index falls in the MGM hash area. . Initialize the list of QPs in a newly-allocated group from AMGM to 0 This is necessary since when a group is moved from AMGM to MGM (in the case where the MGM entry has been emptied of QPs), the AMGM entry is not reset to 0 (and we don't want an extra command to do that).

When a user-space server application calls bind on a socket, then in kernel space this bound socket is considered 'x25-linked' and the SOCK_ZAPPED flag is unset.(As in x25_bind()/af_x25.c). Now when a user-space client application attempts to connect to the server on the listening socket, if the kernel accepts this in-coming call, then it returns a new socket to userland and attempts to reply to the caller. The reply/x25_sendmsg() will fail, because the new socket created on call-accept has its SOCK_ZAPPED flag set by x25_make_new(). (sock_init_data() called by x25_alloc_socket() called by x25_make_new() sets the flag to SOCK_ZAPPED)). Fix: Using the sock_copy_flag() routine available in sock.h fixes this. Tested on 32 and 64 bit kernels with x25 over tcp. Signed-off-by: Shaun Pereira Signed-off-by: Andrew Morton Signed-off-by: David S.

Miller" Date: Fri, 6 Jan 2006 15:36:48 -0800 Subject: [PATCH 1372/2756] [PATCH] Fix posix-cpu-timers sched_time accumulation I've spent the past 3 days digging into a glibc testsuite failure in current CVS, specifically libc/rt/tst-cputimer1.c The thr1 and thr2 timers fire too early in the second pass of this test. The second pass is noteworthy because it makes use of intervals, whereas the first pass does not. All throughout the posix-cpu-timers.c code, the calculation of the process sched_time sum is implemented roughly as: unsigned long long sum; sum = tsk->signal->sched_time; t = tsk; do { sum += t->sched_time; t = next_thread(t); } while (t != tsk); In fact this is the exact scheme used by check_process_timers(). In the case of check_process_timers(), current->sched_time has just been updated (via scheduler_tick(), which is invoked by update_process_times(), which subsequently invokes run_posix_cpu_timers()) So there is no special processing necessary wrt. that. In other contexts, we have to allot for the fact that tsk->sched_time might be a bit out of date if we are current. And the posix-cpu-timers.c code uses current_sched_time() to deal with that. Unfortunately it does so in an erroneous and inconsistent manner in one spot which is what results in the early timer firing. In cpu_clock_sample_group_locked(), it does this: cpu->sched = p->signal->sched_time; /* Add in each other live thread. */ while ((t = next_thread(t)) != p) { cpu->sched += t->sched_time; } if (p->tgid == current->tgid) { /* * We're sampling ourselves, so include the * cycles not yet banked. We still omit * other threads running on other CPUs, * so the total can always be behind as * much as max(nthreads-1,ncpus) * (NSEC_PER_SEC/HZ). */ cpu->sched += current_sched_time(current); } else { cpu->sched += p->sched_time; } The problem is the "p->tgid == current->tgid" test. If "p" is not current, and the tgids are the same, we will add the process t->sched_time twice into cpu->sched and omit "p"'s sched_time which is very very very wrong. posix-cpu-timers.c has a helper function, sched_ns(p) which takes care of this, so my fix is to use that here instead of this special tgid test. The fact that current can be one of the sub-threads of "p" points out that we could make things a little bit more accurate, perhaps by using sched_ns() on every thread we process in these loops. It also points out that we don't use the most accurate value for threads in the group actively running other cpus (and this is mentioned in the comment). But that is a future enhancement, and this fix here definitely makes sense. Signed-off-by: David S.

This is fatal as a lot of X / framebuffer combinations are unable to recover from set_par() reprogramming the graphics controller in KD_GRAPHICS mode. It is also unnecessary as the set_par() function will be called during a switch to KD_TEXT anyway. Because of this no side effects are possible.

Packets visit the FORWARD/LOCAL_OUT and POST_ROUTING hook before the first encapsulation and the LOCAL_OUT and POST_ROUTING hook before each following tunnel mode transform. Patch from Herbert Xu : Move the loop from dst_output into xfrm4_output/xfrm6_output since they're the only ones who need to it. xfrm{4,6}_output_one() processes the first SA all subsequent transport mode SAs and is called in a loop that calls the netfilter hooks between each two calls. In order to avoid the tail call issue, I've added the inline function nf_hook which is nf_hook_slow plus the empty list check. Signed-off-by: Patrick McHardy Signed-off-by: David S.

Use xfrm_decode_session and do the lookup manually, make sure both only do the lookup if the packet hasn't been transformed already. Makeing sure the lookup only happens once needs a new field in the IP6CB, which exceeds the size of skb->cb. The size of skb->cb is increased to 48b.

We adopt the PPC32 approach of having ppc_md callbacks for the kexec functions. The current PPC64 implementation becomes the "default" implementation for PPC64 which platforms can select if they need no special treatment. I've added these default callbacks to pseries/maple/cell/powermac, this means iSeries no longer supports kexec - but it never worked anyway. I've renamed PPC32's machine_kexec_simple to default_machine_kexec, inline with PPC64. Judging by the comments it might be better named machine_kexec_non_of, or something, but at the moment it's the only implementation for PPC32 so it's the "default". Kexec requires machine_shutdown(), which is in machine_kexec.c on PPC32, but we already have in setup-common.c on powerpc. All this does is call ppc_md.nvram_sync, which only powermac implements, so instead make machine_shutdown a ppc_md member and have it call core99_nvram_sync directly on powermac. I've also stuck relocate_kernel.S into misc_32.S for powerpc. Built for ARCH=ppc, and 32 & 64 bit ARCH=powerpc, with KEXEC=y/n. Booted on P5 LPAR and successfully kexec'ed.

The ppc64 code was checking current_thread_info()->flags twice in the syscall exit path; once for TIF_SYSCALL_T_OR_A before disabling interrupts, and then again for TIF_SIGPENDING|TIF_NEED_RESCHED etc after disabling interrupts. Now we do the same as ppc32 -- check the flags only once in the fast path, and re-enable interrupts if necessary in the ptrace case. The patch abolishes the 'syscall_noerror' member of struct thread_info and replaces it with a TIF_NOERROR bit in the flags, which is handled in the slow path. This shortens the syscall entry code, which no longer needs to clear syscall_noerror. The patch adds a TIF_SAVE_NVGPRS flag which causes the syscall exit slow path to save the non-volatile GPRs into a signal frame. This removes the need for the assembly wrappers around sys_sigsuspend(), sys_rt_sigsuspend(), et al which existed solely to save those registers in advance. It also means I don't have to add new wrappers for ppoll() and pselect(), which is what I was supposed to be doing when I got distracted into this... Finally, it unifies the ppc64 and ppc32 methods of handling syscall exit directly into a signal handler (as required by sigsuspend et al) by introducing a TIF_RESTOREALL flag which causes _all_ the registers to be reloaded from the pt_regs by taking the ret_from_exception path, instead of the normal syscall exit path which stomps on the callee-saved GPRs. It appears to pass an LTP test run on ppc64, and passes basic testing on ppc32 too. Brief tests of ptrace functionality with strace and gdb also appear OK. I wouldn't send it to Linus for 2.6.15 just yet though :) Signed-off-by: David Woodhouse Signed-off-by: Paul Mackerras --- arch/powerpc/kernel/asm-offsets.c | 4 +- arch/powerpc/kernel/entry_32.S | 167 +++++++++++++---------- arch/powerpc/kernel/entry_64.S | 214 ++++++++++++++++-------------- arch/powerpc/kernel/signal_32.c | 59 ++++---- arch/powerpc/kernel/signal_64.c | 23 +++- arch/powerpc/kernel/systbl.S | 10 +- include/asm-powerpc/ptrace.h | 2 +- include/asm-powerpc/thread_info.h | 12 +- 8 files changed, 269 insertions(+), 222 deletions(-) diff --git a/arch/powerpc/kernel/asm-offsets.c b/arch/powerpc/kernel/asm-offsets.c index 91538d2445b..3bf89d1a2de 100644 --- a/arch/powerpc/kernel/asm-offsets.c +++ b/arch/powerpc/kernel/asm-offsets.c @@ -92,9 +92,9 @@ int main(void) DEFINE(TI_FLAGS, offsetof(struct thread_info, flags)); DEFINE(TI_PREEMPT, offsetof(struct thread_info, preempt_count)); - DEFINE(TI_SC_NOERR, offsetof(struct thread_info, syscall_noerror)); -#ifdef CONFIG_PPC32 + DEFINE(TI_SIGFRAME, offsetof(struct thread_info, nvgprs_frame)); DEFINE(TI_TASK, offsetof(struct thread_info, task)); +#ifdef CONFIG_PPC32 DEFINE(TI_EXECDOMAIN, offsetof(struct thread_info, exec_domain)); DEFINE(TI_CPU, offsetof(struct thread_info, cpu)); #endif /* CONFIG_PPC32 */ diff --git a/arch/powerpc/kernel/entry_32.S b/arch/powerpc/kernel/entry_32.S index 2e99ae41723..8fed9538f18 100644 --- a/arch/powerpc/kernel/entry_32.S +++ b/arch/powerpc/kernel/entry_32.S @@ -200,8 +200,6 @@ _GLOBAL(DoSyscall) bl do_show_syscall #endif /* SHOW_SYSCALLS */ rlwinm r10,r1,0,0,(31-THREAD_SHIFT) /* current_thread_info() */ - li r11,0 - stb r11,TI_SC_NOERR(r10) lwz r11,TI_FLAGS(r10) andi. r11,r11,_TIF_SYSCALL_T_OR_A bne- syscall_dotrace @@ -222,25 +220,21 @@ ret_from_syscall: bl do_show_syscall_exit #endif mr r6,r3 - li r11,-_LAST_ERRNO - cmplw 0,r3,r11 rlwinm r12,r1,0,0,(31-THREAD_SHIFT) /* current_thread_info() */ - blt+ 30f - lbz r11,TI_SC_NOERR(r12) - cmpwi r11,0 - bne 30f - neg r3,r3 - lwz r10,_CCR(r1) /* Set SO bit in CR */ - oris r10,r10,0x1000 - stw r10,_CCR(r1) - /* disable interrupts so current_thread_info()->flags can't change */ -30: LOAD_MSR_KERNEL(r10,MSR_KERNEL) /* doesn't include MSR_EE */ + LOAD_MSR_KERNEL(r10,MSR_KERNEL) /* doesn't include MSR_EE */ SYNC MTMSRD(r10) lwz r9,TI_FLAGS(r12) - andi. r0,r9,(_TIF_SYSCALL_T_OR_A|_TIF_SIGPENDING|_TIF_NEED_RESCHED) + li r8,-_LAST_ERRNO + andi. r0,r9,(_TIF_SYSCALL_T_OR_A|_TIF_SIGPENDING|_TIF_NEED_RESCHED|_TIF_RESTOREALL) bne- syscall_exit_work + cmplw 0,r3,r8 + blt+ syscall_exit_cont + lwz r11,_CCR(r1) /* Load CR */ + neg r3,r3 + oris r11,r11,0x1000 /* Set SO bit in CR */ + stw r11,_CCR(r1) syscall_exit_cont: #if defined(CONFIG_4xx) || defined(CONFIG_BOOKE) /* If the process has its own DBCR0 value, load it up.

This release is almost identical to the version for the 2.6.14 kernel posted earlier, which is available as part of the Cell BE Linux distribution from http://www.bsc.es/projects/deepcomputing/linuxoncell/. The first patch provides all the interfaces for running spu application, but does not have any support for debugging SPU tasks or for scheduling.

Users that have write permissions on the file system + can use spu_create(2) to establish SPU contexts in the spufs root. + + Every SPU context is represented by a directory containing a predefined + set of files. These files can be used for manipulating the state of the + logical SPU. Users can change permissions on those files, but not actu- + ally add or remove files. + + +MOUNT OPTIONS + uid= + set the user owning the mount point, the default is 0 (root). + + gid= + set the group owning the mount point, the default is 0 (root). + + +FILES + The files in spufs mostly follow the standard behavior for regular sys- + tem calls like read(2) or write(2), but often support only a subset of + the operations supported on regular file systems. This list details the + supported operations and the deviations from the behaviour in the + respective man pages. + + All files that support the read(2) operation also support readv(2) and + all files that support the write(2) operation also support writev(2). + All files support the access(2) and stat(2) family of operations, but + only the st_mode, st_nlink, st_uid and st_gid fields of struct stat + contain reliable information. + + All files support the chmod(2)/fchmod(2) and chown(2)/fchown(2) opera- + tions, but will not be able to grant permissions that contradict the + possible operations, e.g. read access on the wbox file. + + The current set of files is: + + + /mem + the contents of the local storage memory of the SPU. This can be + accessed like a regular shared memory file and contains both code and + data in the address space of the SPU. The possible operations on an + open mem file are: + + read(2), pread(2), write(2), pwrite(2), lseek(2) + These operate as documented, with the exception that seek(2), + write(2) and pwrite(2) are not supported beyond the end of the + file. The file size is the size of the local storage of the SPU, + which normally is 256 kilobytes. + + mmap(2) + Mapping mem into the process address space gives access to the + SPU local storage within the process address space. Only + MAP_SHARED mappings are allowed. + + + /mbox + The first SPU to CPU communication mailbox. This file is read-only and + can be read in units of 32 bits. The file can only be used in non- + blocking mode and it even poll() will not block on it. The possible + operations on an open mbox file are: + + read(2) + If a count smaller than four is requested, read returns -1 and + sets errno to EINVAL. If there is no data available in the mail + box, the return value is set to -1 and errno becomes EAGAIN. + When data has been read successfully, four bytes are placed in + the data buffer and the value four is returned. + + + /ibox + The second SPU to CPU communication mailbox. This file is similar to + the first mailbox file, but can be read in blocking I/O mode, and the + poll familiy of system calls can be used to wait for it. The possible + operations on an open ibox file are: + + read(2) + If a count smaller than four is requested, read returns -1 and + sets errno to EINVAL. If there is no data available in the mail + box and the file descriptor has been opened with O_NONBLOCK, the + return value is set to -1 and errno becomes EAGAIN. + + If there is no data available in the mail box and the file + descriptor has been opened without O_NONBLOCK, the call will + block until the SPU writes to its interrupt mailbox channel. + When data has been read successfully, four bytes are placed in + the data buffer and the value four is returned. + + poll(2) + Poll on the ibox file returns (POLLIN | POLLRDNORM) whenever + data is available for reading. + + + /wbox + The CPU to SPU communation mailbox. It is write-only can can be written + in units of 32 bits. If the mailbox is full, write() will block and + poll can be used to wait for it becoming empty again. The possible + operations on an open wbox file are: write(2) If a count smaller than + four is requested, write returns -1 and sets errno to EINVAL. If there + is no space available in the mail box and the file descriptor has been + opened with O_NONBLOCK, the return value is set to -1 and errno becomes + EAGAIN. + + If there is no space available in the mail box and the file descriptor + has been opened without O_NONBLOCK, the call will block until the SPU + reads from its PPE mailbox channel. When data has been read success- + fully, four bytes are placed in the data buffer and the value four is + returned. + + poll(2) + Poll on the ibox file returns (POLLOUT | POLLWRNORM) whenever + space is available for writing. + + + /mbox_stat + /ibox_stat + /wbox_stat + Read-only files that contain the length of the current queue, i.e. how + many words can be read from mbox or ibox or how many words can be + written to wbox without blocking. The files can be read only in 4-byte + units and return a big-endian binary integer number. The possible + operations on an open *box_stat file are: + + read(2) + If a count smaller than four is requested, read returns -1 and + sets errno to EINVAL. Otherwise, a four byte value is placed in + the data buffer, containing the number of elements that can be + read from (for mbox_stat and ibox_stat) or written to (for + wbox_stat) the respective mail box without blocking or resulting + in EAGAIN. + + + /npc + /decr + /decr_status + /spu_tag_mask + /event_mask + /srr0 + Internal registers of the SPU.

The operations on the fpcr file are: + + read(2) + If a count smaller than four is requested, read returns -1 and + sets errno to EINVAL. Otherwise, a four byte value is placed in + the data buffer, containing the current value of the fpcr regis- + ter. + + write(2) + If a count smaller than four is requested, write returns -1 and + sets errno to EINVAL. Otherwise, a four byte value is copied + from the data buffer, updating the value of the fpcr register. + + + /signal1 + /signal2 + The two signal notification channels of an SPU. These are read-write + files that operate on a 32 bit word. Writing to one of these files + triggers an interrupt on the SPU. The value writting to the signal + files can be read from the SPU through a channel read or from host user + space through the file. After the value has been read by the SPU, it + is reset to zero. The possible operations on an open signal1 or sig- + nal2 file are: + + read(2) + If a count smaller than four is requested, read returns -1 and + sets errno to EINVAL. Otherwise, a four byte value is placed in + the data buffer, containing the current value of the specified + signal notification register. + + write(2) + If a count smaller than four is requested, write returns -1 and + sets errno to EINVAL. Otherwise, a four byte value is copied + from the data buffer, updating the value of the specified signal + notification register. The signal notification register will + either be replaced with the input data or will be updated to the + bitwise OR or the old value and the input data, depending on the + contents of the signal1_type, or signal2_type respectively, + file. + + + /signal1_type + /signal2_type + These two files change the behavior of the signal1 and signal2 notifi- + cation files.

When the context gets sched- + uled to a physical SPU, it starts execution at the instruction pointer + passed in npc. + + Execution of SPU code happens synchronously, meaning that spu_run does + not return while the SPU is still running. If there is a need to exe- + cute SPU code in parallel with other code on either the main CPU or + other SPUs, you need to create a new thread of execution first, e.g. + using the pthread_create(3) call. + + When spu_run returns, the current value of the SPU instruction pointer + is written back to npc, so you can call spu_run again without updating + the pointers. + + event can be a NULL pointer or point to an extended status code that + gets filled when spu_run returns.

This patch creates a new structure that can hold the whole state of a physical SPE in memory. It also contains code that avoids races during the context switch and the binary code that is loaded to the SPU in order to access its registers. The actual PPE- and SPE-side context switch code are two separate patches.

Currently, there is no support for preempting a running SPU thread, they have to leave the SPU by either triggering an event on the SPU that causes it to return to the owning thread or by sending a signal to it. This patch also adds operations that enable accessing an SPU in either runnable or saved state. We use an RW semaphore to protect the state of the SPU from changing underneath us, while we are holding it readable. In order to change the state, it is acquired writeable and a context save or restore is executed before downgrading the semaphore to read-only.

We have various bits of code that try to do it in various place, including some heuristics in prom.c that pre-parse addresses at boot and fill device-nodes "addrs", but those are dodgy at best and I want to deprecate them. So this patch introduces a new set of routines that should be capable of parsing most types of addresses and translating them into CPU physical addresses. It currently works for things on PCI busses and ISA busses and should work on "standard" busses like the root bus or the MacIO bus that don't put funky flags in addresses. If you have other bus types that do use funky flags, you'll have to add new bus type translators, which is fairly easy.

This new version can also detect some PCI serial cards using legacy chips and will probably match those discovered port with the default console choice. Only ppc64 gets udbg still yet, unifying udbg isn't finished yet. It also adds some speed-probing code to udbg so that the default console can come up at the same speed it was set to by the firmware.

The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

The hypervisor locates this area through a pointer at the beginning of the paca, so the structure itself can be located elsewhere. This patch moves the reg_save area out into its own array. This reduces the amount of iSeries specific gunk which is visible to general powerpc code via paca.h Built and booted on POWER5 LPAR and iSeries RS64.

The driver is currently non functional due to this bug. 2) Use in/out macros for register access. 3) Allows m8xx_wdt to use a kernel timer instead of the builtin RTC/PIT for keep-alive trigger (which is responsible for servicing the watchdog until an userspace application takes over). For instance Cyclades PRxK boards (MPC 855T based) have a non-functional internal RTC/PIT unit. Behaviour for boards with RTC/PIT is unchaged. 4) The last change required moving the RTCSC register setting code to a weak function which can be overriden by board specific files. Otherwise the timer init code trashes the register making it impossible for m8xx_wdt to detect the situation.

I'm still concerned that panic strings (not just the one added here) at this stage of booting do not show up on my system. But, that is an issue separate from this patch. Combine get_mem_*_cells() routines to avoid multiple memory node lookups. Added missing of_node_put() call. Changed variable names to help with some confusion as to meaning.

I haven't looked at any of the PPC32 code, if we ever want to support Kdump on PPC we'll have to do another audit, ditto for iSeries. This patch makes PAGE_OFFSET the constant, it'll always be 0xC * 1 gazillion for 64-bit. To get a physical address from a virtual one you subtract PAGE_OFFSET, _not_ KERNELBASE. KERNELBASE is the virtual address of the start of the kernel, it's often the same as PAGE_OFFSET, but _might not be_. If you want to know something's offset from the start of the kernel you should subtract KERNELBASE.

This patch makes it easier to preempt an SPU context by having the scheduler hold ctx->state_sema for much shorter periods of time. As part of this restructuring, the control logic for the "run" operation is moved from arch/ppc64/kernel/spu_base.c to fs/spufs/file.c. Of course the base retains "bottom half" handlers for class{0,1} irqs. The new run loop will re-acquire an SPU if preempted.

This patch reduces lock complexity of SPU scheduler, particularly for involuntary preemptive switches. As a result the new code does a better job of mapping the highest priority tasks to SPUs. Lock complexity is reduced by using the system default workqueue to perform involuntary saves. In this way we avoid nasty lock ordering problems that the previous code had. A "minimum timeslice" for SPU contexts is also introduced. The intent here is to avoid thrashing. While the new scheduler does a better job at prioritization it still does nothing for fairness.

We probably still have a similar problem with blocking read/write on mailbox files, but that will result in extra wakeup in the worst case, not in incorrect behaviour.

This patch still keeps the linear mapping, but looks for proper ibm,dma-window properties to set up larger windows, this makes the maximum supported RAM size 2GB. If there is anything unusual about the dma-window properties, we fall back to the old behavior. We also support switching off the iommu completely now with the regular iommu=off command line option.

Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code. This patch also fixes a bunch of drivers to use the new code instead, so that at least pmac32, pseries, iseries and g5 defconfigs build.

VMALLOC_START is used much more widely, including in generic code, so this patch gets rid of the extraneous VMALLOCBASE. This does require moving the definitions of region IDs from page_64.h to pgtable.h, but they don't clearly belong in the former rather than the latter, anyway. While we're moving them, clean up the definitions of the REGION_IDs: - Abolish REGION_SIZE, it was only used once, to define REGION_MASK anyway - Define the specific region ids in terms of the REGION_ID() macro. - Define KERNEL_REGION_ID in terms of PAGE_OFFSET rather than KERNELBASE. It amounts to the same thing, but conceptually this is about the region of the linear mapping (which starts at PAGE_OFFSET) rather than of the kernel text itself (which is at KERNELBASE).

When written to, this will cause the kernel to discard as much pagecache and/or reclaimable slab objects as it can. THis operation requires root permissions. It won't drop dirty data, so the user should run `sync' first. Caveats: a) Holds inode_lock for exorbitant amounts of time. b) Needs to be taught about NUMA nodes: propagate these all the way through so the discarding can be controlled on a per-node basis. This is a debugging feature: useful for getting consistent results between filesystem benchmarks. We could possibly put it under a config option, but it's less than 300 bytes.

The IPI interrupt may interrupt a processor that is just processing lru requests and cause a race condition. This patch introduces a new function run_on_each_cpu() that uses the keventd() to run the LRU draining on each processor. Processors disable preemption when dealing the LRU caches (these are per processor) and thus executing LRU draining from another process is safe.

Swap migration allows the moving of the physical location of pages between nodes in a numa system while the process is running. This means that the virtual addresses that the process sees do not change. However, the system rearranges the physical location of those pages. The main intent of page migration patches here is to reduce the latency of memory access by moving pages near to the processor where the process accessing that memory is running. The patchset allows a process to manually relocate the node on which its pages are located through the MF_MOVE and MF_MOVE_ALL options while setting a new memory policy. The pages of process can also be relocated from another process using the sys_migrate_pages() function call. Requires CAP_SYS_ADMIN. The migrate_pages function call takes two sets of nodes and moves pages of a process that are located on the from nodes to the destination nodes. Manual migration is very useful if for example the scheduler has relocated a process to a processor on a distant node. A batch scheduler or an administrator can detect the situation and move the pages of the process nearer to the new processor. sys_migrate_pages() could be used on non-numa machines as well, to force all of a particualr process's pages out to swap, if someone thinks that's useful. Larger installations usually partition the system using cpusets into sections of nodes. Paul has equipped cpusets with the ability to move pages when a task is moved to another cpuset. This allows automatic control over locality of a process. If a task is moved to a new cpuset then also all its pages are moved with it so that the performance of the process does not sink dramatically (as is the case today). Swap migration works by simply evicting the page. The pages must be faulted back in. The pages are then typically reallocated by the system near the node where the process is executing. For swap migration the destination of the move is controlled by the allocation policy. Cpusets set the allocation policy before calling sys_migrate_pages() in order to move the pages as intended. No allocation policy changes are performed for sys_migrate_pages(). This means that the pages may not faulted in to the specified nodes if no allocation policy was set by other means. The pages will just end up near the node where the fault occurred. There's another patch series in the pipeline which implements "direct migration". The direct migration patchset extends the migration functionality to avoid going through swap. The destination node of the relation is controllable during the actual moving of pages. The crutch of using the allocation policy to relocate is not necessary and the pages are moved directly to the target. Its also faster since swap is not used. And sys_migrate_pages() can then move pages directly to the specified node. Implement functions to isolate pages from the LRU and put them back later. This patch: An earlier implementation was provided by Hirokazu Takahashi and IWAMOTO Toshihiro for the memory hotplug project. From: Magnus This breaks out isolate_lru_page() and putpack_lru_page().

Page eviction and migration may be useful to migrate pages, to suspend programs or for remapping single pages (useful for faulty pages or pages with soft ECC failures) The process is as follows: The function wanting to migrate pages must first build a list of pages to be migrated or evicted and take them off the lru lists via isolate_lru_page(). isolate_lru_page determines that a page is freeable based on the LRU bit set. Then the actual migration or swapout can happen by calling migrate_pages(). migrate_pages does its best to migrate or swapout the pages and does multiple passes over the list. Some pages may only be swappable if they are not dirty. migrate_pages may start writing out dirty pages in the initial passes over the pages. However, migrate_pages may not be able to migrate or evict all pages for a variety of reasons. The remaining pages may be returned to the LRU lists using putback_lru_pages(). Changelog V4->V5: - Use the lru caches to return pages to the LRU Changelog V3->V4: - Restructure code so that applying patches to support full migration does require minimal changes. Rename swapout_pages() to migrate_pages().

The intent of sys_migrate is to migrate memory of a process. A process may have migrated to another node. Memory was allocated optimally for the prior context. sys_migrate_pages allows to shift the memory to the new node. sys_migrate_pages is also useful if the processes available memory nodes have changed through cpuset operations to manually move the processes memory. Paul Jackson is working on an automated mechanism that will allow an automatic migration if the cpuset of a process is changed. However, a user may decide to manually control the migration. This implementation is put into the policy layer since it uses concepts and functions that are also needed for mbind and friends. The patch also provides a do_migrate_pages function that may be useful for cpusets to automatically move memory. sys_migrate_pages does not modify policies in contrast to Ray's implementation. The current code here is based on the swap based page migration capability and thus is not able to preserve the physical layout relative to it containing nodeset (which may be a cpuset). When direct page migration becomes available then the implementation needs to be changed to do a isomorphic move of pages between different nodesets. The current implementation simply evicts all pages in source nodeset that are not in the target nodeset. Patch supports ia64, i386 and x86_64.

The functionality here is more generic and independent of that patchset.) - Add internal flags MPOL_MF_INVERT to control check_range() behavior. - Replace the pagelist passed through by check_range by a general private pointer that may be used for other purposes. (The following patches will use that to merge numa_maps into mempolicy.c and to better group the page migration code in the policy layer) - Improve some comments.

It uses per-arch L1_CACHE_SHIFT_MAX and people find L1_CACHE_SHIFT_MAX useless. However, we have been using ____cacheline_maxaligned_in_smp to align structures on the internode cacheline size. As per Andi's suggestion, following patch kills ____cacheline_maxaligned_in_smp and introduces INTERNODE_CACHE_SHIFT, which defaults to L1_CACHE_SHIFT for all arches. Arches needing L3/Internode cacheline alignment can define INTERNODE_CACHE_SHIFT in the arch asm/cache.h. Patch replaces ____cacheline_maxaligned_in_smp with ____cacheline_internodealigned_in_smp With this patch, L1_CACHE_SHIFT_MAX can be killed Signed-off-by: Ravikiran Thirumalai Signed-off-by: Shai Fultheim Signed-off-by: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/i386/kernel/init_task.c | 2 +- arch/i386/kernel/irq.c | 2 +- arch/x86_64/kernel/init_task.c | 2 +- include/linux/cache.h | 17 +++++++++++++---- include/linux/ide.h | 2 +- include/linux/mmzone.h | 4 ++-- include/linux/rcupdate.h | 2 +- kernel/rcupdate.c | 4 ++-- mm/sparse.c | 4 ++-- 9 files changed, 24 insertions(+), 15 deletions(-) diff --git a/arch/i386/kernel/init_task.c b/arch/i386/kernel/init_task.c index 9caa8e8db80..cff95d10a4d 100644 --- a/arch/i386/kernel/init_task.c +++ b/arch/i386/kernel/init_task.c @@ -42,5 +42,5 @@ EXPORT_SYMBOL(init_task); * per-CPU TSS segments.

This means that the task_mortuary lock must be acquired with irq disabled in order to avoid intermittent self-deadlock. Since irq is now disabled, the critical section within process_task_mortuary() has been restructured to be O(1) in order to maximize scalability and minimize realtime latency degradation.

For example, if a tag is simply not set in the deleted item, nor anywhere up the tree, radix_tree_delete() would attempt to clear it up the entire height of the tree. Also, tag_set() was made conditional so as not to dirty too many cachelines high up in the radix tree. Instead, put this logic into radix_tree_tag_set().

When CONFIG_SLAB is disabled, the kernel falls back to using the 'SLOB' allocator. SLOB is a traditional K&R/UNIX allocator with a SLAB emulation layer, similar to the original Linux kmalloc allocator that SLAB replaced. It's signicantly smaller code and is more memory efficient. But like all similar allocators, it scales poorly and suffers from fragmentation more than SLAB, so it's only appropriate for small systems. It's been tested extensively in the Linux-tiny tree. I've also stress-tested it with make -j 8 compiles on a 3G SMP+PREEMPT box (not recommended). Here's a comparison for otherwise identical builds, showing SLOB saving nearly half a megabyte of RAM: $ size vmlinux* text data bss dec hex filename 3336372 529360 190812 4056544 3de5e0 vmlinux-slab 3323208 527948 190684 4041840 3dac70 vmlinux-slob $ size mm/{slab,slob}.o text data bss dec hex filename 13221 752 48 14021 36c5 mm/slab.o 1896 52 8 1956 7a4 mm/slob.o /proc/meminfo: SLAB SLOB delta MemTotal: 27964 kB 27980 kB +16 kB MemFree: 24596 kB 25092 kB +496 kB Buffers: 36 kB 36 kB 0 kB Cached: 1188 kB 1188 kB 0 kB SwapCached: 0 kB 0 kB 0 kB Active: 608 kB 600 kB -8 kB Inactive: 808 kB 812 kB +4 kB HighTotal: 0 kB 0 kB 0 kB HighFree: 0 kB 0 kB 0 kB LowTotal: 27964 kB 27980 kB +16 kB LowFree: 24596 kB 25092 kB +496 kB SwapTotal: 0 kB 0 kB 0 kB SwapFree: 0 kB 0 kB 0 kB Dirty: 4 kB 12 kB +8 kB Writeback: 0 kB 0 kB 0 kB Mapped: 560 kB 556 kB -4 kB Slab: 1756 kB 0 kB -1756 kB CommitLimit: 13980 kB 13988 kB +8 kB Committed_AS: 4208 kB 4208 kB 0 kB PageTables: 28 kB 28 kB 0 kB VmallocTotal: 1007312 kB 1007312 kB 0 kB VmallocUsed: 48 kB 48 kB 0 kB VmallocChunk: 1007264 kB 1007264 kB 0 kB (this work has been sponsored in part by CELF) From: Ingo Molnar Fix 32-bitness bugs in mm/slob.c.

As previously submitted, the pair of masks defined a map of the positions of the set bits in A to the corresponding bits in B. This is still true. The issue is how to map the other positions, corresponding to the unset (0) bits in A. As previously submitted, they were all mapped to the first set bit position in B, a constant map. When I tried to code per-vma mempolicy rebinding using these remap operators, I realized this was wrong. This patch changes the default to map all the unset bit positions in A to the same positions in B, the identity map. For example, if A has bits 4-7 set, and B has bits 9-12 set, then the map defined by the pair maps each bit position in the first 32 bits as follows: 0 ==> 0 ... 3 ==> 3 4 ==> 9 ... 7 ==> 12 8 ==> 8 9 ==> 9 ... 31 ==> 31 This now corresponds to the typical behaviour desired when migrating pages and policies from one cpuset to another. The pages on nodes within the original cpuset, and the references in memory policies to nodes within the original cpuset, are migrated to the corresponding cpuset-relative nodes in the destination cpuset. Other pages and node references are left untouched.

This enables batch managers monitoring jobs running in dedicated cpusets to efficiently detect what level of memory pressure that job is causing. This is useful both on tightly managed systems running a wide mix of submitted jobs, which may choose to terminate or reprioritize jobs that are trying to use more memory than allowed on the nodes assigned them, and with tightly coupled, long running, massively parallel scientific computing jobs that will dramatically fail to meet required performance goals if they start to use more memory than allowed to them. This patch just provides a very economical way for the batch manager to monitor a cpuset for signs of memory pressure. It's up to the batch manager or other user code to decide what to do about it and take action. ==> Unless this feature is enabled by writing "1" to the special file /dev/cpuset/memory_pressure_enabled, the hook in the rebalance code of __alloc_pages() for this metric reduces to simply noticing that the cpuset_memory_pressure_enabled flag is zero. So only systems that enable this feature will compute the metric. Why a per-cpuset, running average: Because this meter is per-cpuset, rather than per-task or mm, the system load imposed by a batch scheduler monitoring this metric is sharply reduced on large systems, because a scan of the tasklist can be avoided on each set of queries. Because this meter is a running average, instead of an accumulating counter, a batch scheduler can detect memory pressure with a single read, instead of having to read and accumulate results for a period of time. Because this meter is per-cpuset rather than per-task or mm, the batch scheduler can obtain the key information, memory pressure in a cpuset, with a single read, rather than having to query and accumulate results over all the (dynamically changing) set of tasks in the cpuset. A per-cpuset simple digital filter (requires a spinlock and 3 words of data per-cpuset) is kept, and updated by any task attached to that cpuset, if it enters the synchronous (direct) page reclaim code.

It's up to the +batch manager or other user code to decide what to do about it and +take action. + +==> Unless this feature is enabled by writing "1" to the special file + /dev/cpuset/memory_pressure_enabled, the hook in the rebalance + code of __alloc_pages() for this metric reduces to simply noticing + that the cpuset_memory_pressure_enabled flag is zero.

The cpuset_fork() call in fork.c was setting up the correct task->cpuset pointer after the tasklist_lock was dropped, which briefly exposed the newly forked process with an unsafe (copied from parent without locks or usage counter increment) cpuset pointer. In theory, that exposed cpuset pointer could have been pointing at a cpuset that was already freed and removed, and in theory another task that had been sitting on the tasklist_lock waiting to scan the task list could have raced down the entire tasklist, found our new child at the far end, and dereferenced that bogus cpuset pointer. To fix, setup up the correct cpuset pointer in the new child by calling cpuset_fork() before the new task is linked into the tasklist, and with that, add a fork failure case, to dereference that cpuset, if the fork fails along the way, after cpuset_fork() was called. Had to remove a BUG_ON() from cpuset_exit(), because it was no longer valid - the call to cpuset_exit() from a failed fork would not have PF_EXITING set.

The real motivator for this cleanup patch is to lay more groundwork for the upcoming patch to correctly rebind NUMA mempolicies that are attached to vma's after the containing cpuset memory placement changes. NUMA mempolicies are constrained by the cpuset their task is a member of. When either (1) a task is moved to a different cpuset, or (2) the 'mems' mems_allowed of a cpuset is changed, then the NUMA mempolicies have embedded node numbers (for MPOL_BIND, MPOL_INTERLEAVE and MPOL_PREFERRED) that need to be recalculated, relative to their new cpuset placement. The old code used an unreliable method of determining what was the old mems_allowed constraining the mempolicy. It just looked at the tasks mems_allowed value. This sort of worked with the present code, that just rebinds the -task- mempolicy, and leaves any -vma- mempolicies broken, referring to the old nodes. But in an upcoming patch, the vma mempolicies will be rebound as well. Then the order in which the various task and vma mempolicies are updated will no longer be deterministic, and one can no longer count on the task->mems_allowed holding the old value for as long as needed. It's not even clear if the current code was guaranteed to work reliably for task mempolicies. So I added a mems_allowed field to each mempolicy, stating exactly what mems_allowed the policy is relative to, and updated synchronously and reliably anytime that the mempolicy is rebound. Also removed a useless wrapper routine, numa_policy_rebind(), and had its caller, cpuset_update_task_memory_state(), call directly to the rewritten policy_rebind() routine, and made that rebind routine extern instead of static, and added a "mpol_" prefix to its name, making it mpol_rebind_policy().

NUMA mempolicies (mm/mempolicy.c) are constrained by the current tasks cpuset to just the Memory Nodes allowed by that cpuset. The kernel maintains internal state for each mempolicy, tracking what nodes are used for the MPOL_INTERLEAVE, MPOL_BIND or MPOL_PREFERRED policies. When a tasks cpuset memory placement changes, whether because the cpuset changed, or because the task was attached to a different cpuset, then the tasks mempolicies have to be rebound to the new cpuset placement, so as to preserve the cpuset-relative numbering of the nodes in that policy. An earlier fix handled such mempolicy rebinding for mempolicies attached to a task. This fix rebinds mempolicies attached to vma's (address ranges in a tasks address space.) Due to the need to hold the task->mm->mmap_sem semaphore while updating vma's, the rebinding of vma mempolicies has to be done when the cpuset memory placement is changed, at which time mmap_sem can be safely acquired. The tasks mempolicy is rebound later, when the task next attempts to allocate memory and notices that its task->cpuset_mems_generation is out-of-date with its cpusets mems_generation. Because walking the tasklist to find all tasks attached to a changing cpuset requires holding tasklist_lock, a spinlock, one cannot update the vma's of the affected tasks while doing the tasklist scan. In general, one cannot acquire a semaphore (which can sleep) while already holding a spinlock (such as tasklist_lock). So a list of mm references has to be built up during the tasklist scan, then the tasklist lock dropped, then for each mm, its mmap_sem acquired, and the vma's in that mm rebound. Once the tasklist lock is dropped, affected tasks may fork new tasks, before their mm's are rebound. A kernel global 'cpuset_being_rebound' is set to point to the cpuset being rebound (there can only be one; cpuset modifications are done under a global 'manage_sem' semaphore), and the mpol_copy code that is used to copy a tasks mempolicies during fork catches such forking tasks, and ensures their children are also rebound. When a task is moved to a different cpuset, it is easier, as there is only one task involved. It's mm->vma's are scanned, using the same mpol_rebind_policy() as used above. It may happen that both the mpol_copy hook and the update done via the tasklist scan update the same mm twice. This is ok, as the mempolicies of each vma in an mm keep track of what mems_allowed they are relative to, and safely no-op a second request to rebind to the same nodes.

The previous code didn't actually attempt to migrate the pages of the tasks in a cpuset whose memory placement changed until the next time each such task tried to allocate memory. This was undesirable, as users invoking memory page migration exected to happen when the placement changed, not some unspecified time later when the task needed more memory. It is now trivial to handle the page migration at the same time as the per-vma rebinding is done. The routine cpuset.c:update_nodemask(), which handles changing a cpusets memory placement ('mems') now checks for the special case of being asked to write a placement that is the same as before. It was harmless enough before to just recompute everything again, even though nothing had changed. But page migration is a heavy weight operation - moving pages about. So now it is worth avoiding that if asked to move a cpuset to its current location.

On each page allocation, the cpuset hook needs to check for a possible change in the current tasks cpuset. It can now handle the common case, of no change, without taking any spinlock or semaphore, thanks to RCU. Convert a spinlock on the current task to an rcu_read_lock(), saving approximately a memory barrier and an atomic op, depending on architecture. This is done by adding rcu_assign_pointer() and synchronize_rcu() calls to the write side of the task->cpuset pointer, in cpuset.c:attach_task(), to delay freeing up a detached cpuset until after any critical sections referencing that pointer. Thanks to Andi Kleen, Nick Piggin and Eric Dumazet for ideas.

For some platforms, this is critical to setup correctly, particularly those which the setting is dependent on the device. Currently, ARM drivers do (eg) the following: err = request_irq(irq, ...); set_irq_type(irq, IRQT_RISING); However, if the interrupt has previously been programmed to be level sensitive (for whatever reason) then this will cause an interrupt storm. Hence, if we combine set_irq_type() with request_irq(), we can then safely set the type prior to unmasking the interrupt. The unfortunate problem is that in order to support this, these flags need to be visible outside of the ARM architecture - drivers such as smc91x need these flags and they're cross-architecture. Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the property that the device would like. The IRQ controller code should do its best to select the most appropriate supported mode.

Even if ->prepare_write() returns an error, it may already have added some blocks. So, this truncates blocks outside of ->i_size by vmtruncate(). - Add generic_cont_expand_simple(). The generic_cont_expand_simple() assumes that ->prepare_write() can handle the block boundary. With this, we don't need to care the extra byte. And for expanding a file size by truncate(), fatfs uses the added generic_cont_expand_simple().

See mm/filemap.c: And changes the filemap_write_and_wait() and filemap_write_and_wait_range(). Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite() returns error. However, even if filemap_fdatawrite() returned an error, it may have submitted the partially data pages to the device. (e.g. in the case of -ENOSPC) Andrew Morton writes, If filemap_fdatawrite() returns an error, this might be due to some I/O problem: dead disk, unplugged cable, etc. Given the generally crappy quality of the kernel's handling of such exceptions, there's a good chance that the filemap_fdatawait() will get stuck in D state forever. So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO. Trond, could you please review the nfs part? Especially I'm not sure, nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.

These patches adds support for non-relay files (relayfs_create_file()). This is so relayfs applications can create 'control files' in relayfs itself rather than in /proc or via a netlink channel, as is currently done in the relay-app examples. Basically what this amounts to is exporting relayfs_create_file() with an additional file_ops param that clients can use to supply file operations for their own special-purpose files in relayfs. - make exported relay file ops useful (patches 7-8) The relayfs relay_file_operations have always been exported, the intent being to make it possible to create relay files in other filesystems such as debugfs. The problem, though, is that currently the file operations are too tightly coupled to relayfs to actually be used for this purpose. This patch fixes that by adding a couple of callback functions that allow a client to hook into relay_open()/close() and supply the files that will be used to represent the channel buffers; the default implementation if no callbacks are defined is to create the files in relayfs. - add an option to create global relay buffer (patches 9-10) The file creation callback also supplies an optional param, is_global, that can be used by clients to create a single global relayfs buffer instead of the default per-cpu buffers. This was suggested as being useful for certain debugging applications where it's more convenient to be able to get all the data from a single channel without having to go to the bother of dealing with per-cpu files. - cleanup, some renaming and Documentation updates (patches 11-12) There were several comments that the use of netlink in the example code was non-intuitive and in fact the whole relay-app business was needlessly confusing. Based on that feedback, the example code has been completely converted over to relayfs control files as supported by this patch, and have also been made completely self-contained. The converted examples along with a couple of new examples that demonstrate using exported relay files can be found in relay-apps tarball: http://prdownloads.sourceforge.net/relayfs/relay-apps-0.9.tar.gz?download This patch: Separate buffer create/destroy from inode create/destroy. We want to be able to associate other data and not just relay buffers with inodes. Buffer create/destroy is moved out of inode.c and into relayfs core code.

SUS requires that when truncating a file to the size that it currently is: truncate and ftruncate should NOT modify ctime or mtime O_TRUNC SHOULD modify ctime and mtime. Currently mtime and ctime are always modified on most local filesystems (side effect of ->truncate) or never modified (on NFS). With this patch: ATTR_CTIME|ATTR_MTIME are sent with ATTR_SIZE precisely when an update of these times is required whether size changes or not (via a new argument to do_truncate). This allows NFS to do the right thing for O_TRUNC. inode_setattr nolonger forces ATTR_MTIME|ATTR_CTIME when the ATTR_SIZE sets the size to it's current value. This allows local filesystems to do the right thing for f?truncate. Also, the logic in inode_setattr is changed a bit so there are two return points. One returns the error from vmtruncate if it failed, the other returns 0 (there can be no other failure). Finally, if vmtruncate succeeds, and ATTR_SIZE is the only change requested, we now fall-through and mark_inode_dirty. If a filesystem did not have a ->truncate function, then vmtruncate will have changed i_size, without marking the inode as 'dirty', and I think this is wrong.

If some aspect of this range does not fit in the 32bit structure, something needs to be done. The current code is wrong in several respects: - It returns data to userspace even if no conflict was found i.e. it should check l_type for F_UNLCK - It returns -EOVERFLOW too agressively. A lock range covering the last possible byte of the file (start = COMPAT_OFF_T_MAX, len = 1) should be possible, but is rejected with the current test. - A extra-long 'len' should not be a problem. If only that part of the conflicting lock that would be visible to the 32bit app needs to be reported to the 32bit app anyway. This patch addresses those three issues and adds a comment to (hopefully) record it for posterity. Note: this patch mainly affects test-cases. Real applications rarely is ever see the problems. This patch has been tested (LSB test suite), and works.

After some discussion it was concluded that duplicate valid keys should probably be discarded also as they would otherwise hide the new key.

The patch makes the following changes: (1) A new, optional key type method has been added. This permits a key type to intercept requests at the point /sbin/request-key is about to be spawned and do something else with them - passing them over the rpc_pipefs files or netlink sockets for instance. The uninstantiated key, the authorisation key and the intended operation name are passed to the method. (2) The callout_info is no longer passed as an argument to /sbin/request-key to prevent unauthorised viewing of this data using ps or by looking in /proc/pid/cmdline. This means that the old /sbin/request-key program will not work with the patched kernel as it will expect to see an extra argument that is no longer there. A revised keyutils package will be made available tomorrow. (3) The callout_info is now attached to the authorisation key. Reading this key will retrieve the information. (4) A new field has been added to the task_struct. This holds the authorisation key currently active for a thread. Searches now look here for the caller's set of keys rather than looking for an auth key in the lowest level of the session keyring. This permits a thread to be servicing multiple requests at once and to switch between them. Note that this is per-thread, not per-process, and so is usable in multithreaded programs. The setting of this field is inherited across fork and exec. (5) A new keyctl function (KEYCTL_ASSUME_AUTHORITY) has been added that permits a thread to assume the authority to deal with an uninstantiated key. Assumption is only permitted if the authorisation key associated with the uninstantiated key is somewhere in the thread's keyrings. This function can also clear the assumption. (6) A new magic key specifier has been added to refer to the currently assumed authorisation key (KEY_SPEC_REQKEY_AUTH_KEY). (7) Instantiation will only proceed if the appropriate authorisation key is assumed first. The assumed authorisation key is discarded if instantiation is successful. (8) key_validate() is moved from the file of request_key functions to the file of permissions functions. (9) The documentation is updated. From: Build fix.

This patch moves that to common code [1] and adds a ->getgeo method to fill out the raw kernel hd_geometry structure. For many drivers this means ->ioctl can go away now. [1] the s390 block drivers are odd in this respect. xpram sets ->start to 4 always which seems more than odd, and the dasd driver shifts the start offset around, probably because of it's non-standard sector size.

So any thread except group_exit_task will go to handle_group_stop()->finish_stop(). However, when group_exit_task actually starts do_coredump(), it sets SIGNAL_GROUP_EXIT, but does not reset ->group_stop_count while killing other threads. If we have not yet stopped threads in the same thread group, they all will spin in kernel mode until group_exit_task sends them SIGKILL, because ->group_stop_count > 0 means: recalc_sigpending_tsk() never clears TIF_SIGPENDING get_signal_to_deliver() goes to handle_group_stop() handle_group_stop() returns when SIGNAL_GROUP_EXIT set syscall_exit/resume_userspace notice TIF_SIGPENDING, call get_signal_to_deliver() again. So we are wasting cpu cycles, and if one of these threads is rt_task() this may be a serious problem. NOTE: do_coredump() holds ->mmap_sem, so not stopped threads can't escape coredumping after clearing ->group_stop_count.

CPU architectures permit +partitioning support, where compute resources of a single CPU could be made +available to virtual machine environments. There are couple OEMS that +support NUMA hardware which are hot pluggable as well, where physical +node insertion and removal require support for CPU hotplug. + +Such advances require CPUs available to a kernel to be removed either for +provisioning reasons, or for RAS purposes to keep an offending CPU off +system execution path. Hence the need for CPU hotplug support in the +Linux kernel. + +A more novel use of CPU-hotplug support is its use today in suspend +resume support for SMP. Dual-core and HT support makes even +a laptop run SMP kernels which didn't support these methods. SMP support +for suspend/resume is a work in progress. + +General Stuff about CPU Hotplug +-------------------------------- + +Command Line Switches +--------------------- +maxcpus=n Restrict boot time cpus to n. Say if you have 4 cpus, using + maxcpus=2 will only boot 2. You can choose to bring the + other cpus later online, read FAQ's for more info. + +additional_cpus=n [x86_64 only] use this to limit hotpluggable cpus. + This option sets + cpu_possible_map = cpu_present_map + additional_cpus + +CPU maps and such +----------------- +[More on cpumaps and primitive to manipulate, please check +include/linux/cpumask.h that has more descriptive text.] + +cpu_possible_map: Bitmap of possible CPUs that can ever be available in the +system. This is used to allocate some boot time memory for per_cpu variables +that aren't designed to grow/shrink as CPUs are made available or removed. +Once set during boot time discovery phase, the map is static, i.e no bits +are added or removed anytime. Trimming it accurately for your system needs +upfront can save some boot time memory. See below for how we use heuristics +in x86_64 case to keep this under check. + +cpu_online_map: Bitmap of all CPUs currently online. Its set in __cpu_up() +after a cpu is available for kernel scheduling and ready to receive +interrupts from devices. Its cleared when a cpu is brought down using +__cpu_disable(), before which all OS services including interrupts are +migrated to another target CPU. + +cpu_present_map: Bitmap of CPUs currently present in the system. Not all +of them may be online. When physical hotplug is processed by the relevant +subsystem (e.g ACPI) can change and new bit either be added or removed +from the map depending on the event is hot-add/hot-remove. There are currently +no locking rules as of now. Typical usage is to init topology during boot, +at which time hotplug is disabled. + +You really dont need to manipulate any of the system cpu maps. They should +be read-only for most use. When setting up per-cpu resources almost always use +cpu_possible_map/for_each_cpu() to iterate. + +Never use anything other than cpumask_t to represent bitmap of CPUs. + +#include + +for_each_cpu - Iterate over cpu_possible_map +for_each_online_cpu - Iterate over cpu_online_map +for_each_present_cpu - Iterate over cpu_present_map +for_each_cpu_mask(x,mask) - Iterate over some random collection of cpu mask. + +#include +lock_cpu_hotplug() and unlock_cpu_hotplug(): + +The above calls are used to inhibit cpu hotplug operations. While holding the +cpucontrol mutex, cpu_online_map will not change. If you merely need to avoid +cpus going away, you could also use preempt_disable() and preempt_enable() +for those sections. Just remember the critical section cannot call any +function that can sleep or schedule this process away. The preempt_disable() +will work as long as stop_machine_run() is used to take a cpu down. + +CPU Hotplug - Frequently Asked Questions. + +Q: How to i enable my kernel to support CPU hotplug? +A: When doing make defconfig, Enable CPU hotplug support + + "Processor type and Features" -> Support for Hotpluggable CPUs + +Make sure that you have CONFIG_HOTPLUG, and CONFIG_SMP turned on as well. + +You would need to enable CONFIG_HOTPLUG_CPU for SMP suspend/resume support +as well. + +Q: What architectures support CPU hotplug? +A: As of 2.6.14, the following architectures support CPU hotplug. + +i386 (Intel), ppc, ppc64, parisc, s390, ia64 and x86_64 + +Q: How to test if hotplug is supported on the newly built kernel? +A: You should now notice an entry in sysfs. + +Check if sysfs is mounted, using the "mount" command.

Also online file will report +the state as 0 when a cpu if offline and 1 when its online. + +#To display the current cpu state. +#cat /sys/devices/system/cpu/cpuX/online + +Q: Why cant i remove CPU0 on some systems? +A: Some architectures may have some special dependency on a certain CPU. + +For e.g in IA64 platforms we have ability to sent platform interrupts to the +OS. a.k.a Corrected Platform Error Interrupts (CPEI). In current ACPI +specifications, we didn't have a way to change the target CPU. Hence if the +current ACPI version doesn't support such re-direction, we disable that CPU +by making it not-removable. + +In such cases you will also notice that the online file is missing under cpu0. + +Q: How do i find out if a particular CPU is not removable? +A: Depending on the implementation, some architectures may show this by the +absence of the "online" file. This is done if it can be determined ahead of +time that this CPU cannot be removed. + +In some situations, this can be a run time check, i.e if you try to remove the +last CPU, this will not be permitted.

Then RCU was added and dentry struct enlarged by two pointers, with nice results for SMP, but not so good on UP, because breaking the above tuning (128 + 8 = 136 bytes) This patch reverts this unwanted side effect, by using an union (d_u), where d_rcu and d_child are placed so that these two fields can share their memory needs. At the time d_free() is called (and d_rcu is really used), d_child is known to be empty and not touched by the dentry freeing. Lockless lookups only access d_name, d_parent, d_lock, d_op, d_flags (so the previous content of d_child is not needed if said dentry was unhashed but still accessed by a CPU because of RCU constraints) As dentry cache easily contains millions of entries, a size reduction is worth the extra complexity of the ugly C union.

Such a situation never arises with the default linker scripts, but there's nothing inherently wrong with zero-filesize (but non-zero memsize) ELF segments. Custom linker scripts can generate them, and the kernel should be able to map them; this patch makes it so.

Biederman" Date: Sun, 8 Jan 2006 01:03:46 -0800 Subject: [PATCH 1685/2756] [PATCH] Don't attempt to power off if power off is not implemented The problem. It is expected that /sbin/halt -p works exactly like /sbin/halt, when the kernel does not implement power off functionality. The kernel can do a lot of work in the reboot notifiers and in device_shutdown before we even get to machine_power_off. Some of that shutdown is not safe if you are leaving the power on, and it definitely gets in the way of using sysrq or pressing ctrl-alt-del. Since the shutdown happens in generic code there is no way to fix this in architecture specific code :( Some machines are kernel oopsing today because of this. The simple solution is to turn LINUX_REBOOT_CMD_POWER_OFF into LINUX_REBOOT_CMD_HALT if power_off functionality is not implemented. This has the unfortunate side effect of disabling the power off functionality on architectures that leave pm_power_off to null and still implement something in machine_power_off. And it will break the build on some architectures that don't have a pm_power_off variable at all. On both counts I say tough. For architectures like alpha that don't implement the pm_power_off variable pm_power_off is declared in linux/pm.h and it is a generic part of our power management code, and all architectures should implement it. For architectures like parisc that have a default power off method in machine_power_off if pm_power_off is not implemented or fails. It is easy enough to set the pm_power_off variable. And nothing bad happens there, the machines just stop powering off. The current semantics are impossible without a flag at the top level so we can avoid the problem code if a power off is not implemented. pm_power_off is as good a flag as any with the bonus that it works without modification on at least x86, x86_64, powerpc, and ppc today. Andrew can you pick this up and put this in the mm tree. Kernels that don't compile or don't power off seem saner than kernels that oops or panic. Until we get the arch specific patches for the problem architectures this probably isn't smart to push into the stable kernel.

This function determines what type of interrupt vector to use, i.e., MSI, MSI-X, or IO-APIC. One noticeable difference is changing the interrupt field of the controller struct to an array of 4 unsigned ints. The Smart Array HW is capable of generating 4 distinct interrupts depending on the transport method in use during operation. These are: #define DOORBELL_INT 0 Used to notify the contoller of configuration updates. We only use this feature when in polling mode. #define PERF_MODE_INT 0 Used when the controller is in Performant Mode. #define SIMPLE_MODE_INT 2 Used when the controller is in Simple Mode (current Linux implementation). #define MEMQ_INT_MODE 3 Not used. When using IO-APIC interrupts these 4 lines are OR'ed together so when any one fires an interrupt an is generated. In MSI or MSI-X mode this hardware OR'ing is ignored. We must register for our interrupt depending on what mode the controller is running. For Linux we use SIMPLE_MODE_INT exclusively at this time. Please consider this for inclusion.

This is analogous to validation we already perform in the read/write paths. The identity mapping scheme used on ia64 requires that each 16MB or 64MB granule be accessed with exactly one attribute (write-back or uncacheable). This avoids "attribute aliasing", which can cause a machine check. Sample problem scenario: - Machine supports VGA, so it has uncacheable (UC) MMIO at 640K-768K - efi_memmap_init() discards any write-back (WB) memory in the first granule - Application (e.g., "hwinfo") mmaps /dev/mem, offset 0 - hwinfo receives UC mapping (the default, since memmap says "no WB here") - Machine check abort (on chipsets that don't support UC access to WB memory, e.g., sx1000) In the scenario above, the only choices are - Use WB for hwinfo mmap. Can't do this because it causes attribute aliasing with the UC mapping for the VGA MMIO space. - Use UC for hwinfo mmap. Can't do this because the chipset may not support UC for that region. - Disallow the hwinfo mmap with -EINVAL. That's what this patch does.

We used to hardcode 0, but that broke on systems where !cpu_possible(0) when workqueue_struct->cpu_workqueue_struct was changed from a static array to alloc_percpu. Commit id bce61dd49d6ba7799be2de17c772e4c701558f14 ("Fix hardcoded cpu=0 in workqueue for per_cpu_ptr() calls") fixed that for Ben's funky sparc64 system, but it regressed my Power5. Offlining cpu 0 oopses upon the next call to queue_work for a single-thread workqueue, because now we try to manipulate per_cpu_ptr(wq->cpu_wq, 1), which is uninitialized. So we need to establish an unchanging "slot" for single-thread workqueues which will have a valid percpu allocation. Since alloc_percpu keys off of cpu_possible_map, which must not change after initialization, make this slot == first_cpu(cpu_possible_map).

In a hypervisor based setup, direct access to the first priviledged register space can typically not be allowed to the kernel and has to be implemented through hypervisor calls. As suggested by Masato Noguchi, let's abstract the register access trough a number of function calls. Since there is currently no public specification of actual hypervisor calls to implement this, I only provide a place that makes it easier to hook into.

However, we also have the following, in arch/ppc/boot/common/util.S: .section ".relocate_code","xa" [...] _GLOBAL(flush_instruction_cache) [...] _GLOBAL(flush_data_cache) [...] The addition of the .text section definition in the definition of _GLOBAL overrides the .relocate_code section definition. As a result, these two functions don't end up in .relocate_code, so they don't get relocated correctly, and the boot fails. There's another suspicious-looking usage at kernel/swsusp.S:37 that someone should look into. I did not exhaustively search the source tree, though. The following is the minimal patch that fixes the immediate problem.

This one removes the old PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them both with a single stub driver that uses the new PowerMac low i2c layer. Now that i2c-keywest is gone, the low-i2c code is extended to support interrupt driver transfers. All i2c busses now appear as platform devices. Compatibility with existing drivers should be maintained as the i2c bus names have been kept identical, except for the SMU bus but in that later case, all users has been fixed. With that patch added, matching a device node to an i2c_adapter becomes trivial.

It adds the ability to execute those do-platform-* scripts in the device-tree (at least for most devices for which a backend is provided). This should replace the clock spreading hacks properly. It might also have an impact on all sort of machines since some of the scripts marked "at init" will now be executed on boot (or some other on sleep/wakeup), those will possibly do things that the kernel didn't do at all, like setting some values into some i2c devices (changing thermal sensor calibration or conversion rate) etc... Thus regression testing is MUCH welcome. Also loook for errors in dmesg. That's also why I've left rather verbose debugging enabled in this version of the patch. (I do expect some Windtunnel G4s to show some errors as they have an i2c clock chip on the PMU bus that uses some primitives that the i2c backend doesn't implement yet. I really need users that have one of those machine to come back to me so we can get that done right, though the errors themselves should be harmless, I suspect the machine might not run at full speed).

The only G5 models still lacking cpufreq support at this point are the Xserve and possibly the new iMac iSight (not tested). I'll have those added soon. That patch uses the new platform functions interpreter to implement frequency and voltage switching on most models. Note that in order to find the low frequency value, I had to hack something that might now work properly on all models, so if the frequency value reported when running low speed looks bogus to you, please report it to me.

The hardware also has to build the ICV. Previously, the host_build_iv flag couldn't be used at all for WEP, and not alone (with both host_decrypt and host_encrypt disabled) because the crypto algorithm wasn't assigned. This is also fixed.

An ATA interrupt condition is mysteriously present at start of day. If we took too long in issuing the first command, the kernel would basically get tired of the spurious interrupts and turn the interrupt off. Issuing the first command essentially causes the interrupt condition to get acknowledged. I haven't seen this happen with any other drives. What I basically do is ack ATA status by reading it regardless of whether we're expecting to have to handle an interrupt. This clears the start-of-day anomalous interrupt condition, and keeps the kernel from disabling that interrupt due to too many spurious interrupts. Also, I fixed a bug where hotplug interrupts weren't getting acknowledged as handled in the ISR. This was not the cause of the spurious interrupts, but it's the right thing to do anyway.

Unfortunately, there does not seem to be any code handling the v4l2 ioctls, so quite often the code goes through two separate conversions, first from 32 bit v4l to 64 bit v4l, and from there to 64 bit v4l2. My patch does not change that, so there is still much room for improvement. Also, some drivers have additional ioctl numbers, for which the conversion should be handled internally to that driver.

Remove dead code and volume scaling from msp3400.c. Volume scaling does not belong there, it should be done in the driver for the card that uses the msp3400 if needed, not in the msp3400.c source. The volume scaling code gave problems with the ivtv driver which does not need to do any scaling.

In effect, the blackbird will query the tuner V4L2_STD_xxxx definitions to determine whether it's connected to a NTSC or PAL tuner. Based on that, various default values will change for blackbird encoding. - Fixes back panel SVIDEO/COMPOSITE with audio, work properly. - Fixes a problem with lip sync issues, due to bad framerate vs audio rate assumptions. - Fixed a problem with the GPIO configuration in cx88-cards. - Removed the comments in cx88-cards that made no sense.

They also returned an inaccurate VBI offset. - V4L2_(G|S)_FMT and V4L2_TRY_FMT disagreed about the start of VBI capturing in PAL and SECAM second field. Note the start line fixes may break applications using VIDIOCSVBIFMT because this ioctl fails when the driver does not support exactly the requested parameters. - V4L2_TRY_FMT did not clear the reserved field in struct v4l2_vbi_format. - V4L2_(S|TRY)_FMT did not expect very large or small VBI start or count values, returning wrong (but safe) counts due to an overflow. - VIDIOCGVBIFMT confused V4L and V4L2 VBI flags.

The cardtype is no longer necessary with the general video input change. - Update VIDIOC_LOG_STATUS output to show the video and audio inputs separately.

If this is really needed one day then it should be implemented using VIDIOC_G/S_REGISTER. - Added missing BALANCE control info for VIDIOC_QUERYCTRL. - Still more cleanup, clarified some kernel messages.

This ensures a unique prefix for each device instance. - At a later stage these macros may be reimplemented using the device-generic macros from device.h. - Converted the msp3400 driver to the new macros.

Most of the stuff has been tested in the mm tree. Main advantages: ============ - vxres > xres support - ywrap and xpan support - much faster for almost all modes (e.g. 1280x1024-16bpp draws more than 41 full screens of text instead of about 25 full screens of text per second on authors Epia 5000) - module init/exit code fixed - bugs triggered by console rotation fixed - lots of minor improvements - startup modes suitable for high performance scrolling in all directions This diff also contains a lot of white space fixes. No side effects are possible, only one single graphics core is affected.
