From bda663d36b94c723153246a4231bbc0f1cd1836e Mon Sep 17 00:00:00 2001 From: Robert Moore Date: Fri, 16 Sep 2005 16:51:15 -0400 Subject: [PATCH 0001/1843] [ACPI] ACPICA 20050916 Fixed a problem within the Resource Manager where support for the Generic Register descriptor was not fully implemented. This descriptor is now fully recognized, parsed, disassembled, and displayed. Restructured the Resource Manager code to utilize table-driven dispatch and lookup, eliminating many of the large switch() statements. This reduces overall subsystem code size and code complexity. Affects the resource parsing and construction, disassembly, and debug dump output. Cleaned up and restructured the debug dump output for all resource descriptors. Improved readability of the output and reduced code size. Fixed a problem where changes to internal data structures caused the optional ACPI_MUTEX_DEBUG code to fail compilation if specified.

Factor out the _PDC invocation so Linux invokes it only once. http://bugzilla.kernel.org/show_bug.cgi?id=5483 Signed-off-by: Venkatesh Pallipadi Signed-off-by: Len Brown --- arch/i386/kernel/acpi/Makefile | 2 +- arch/i386/kernel/acpi/cstate.c | 58 -------------- arch/i386/kernel/acpi/processor.c | 75 +++++++++++++++++++ arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.c | 67 ----------------- .../kernel/cpu/cpufreq/speedstep-centrino.c | 12 --- arch/ia64/kernel/cpufreq/Makefile | 5 ++ arch/ia64/kernel/cpufreq/acpi-cpufreq.c | 51 ------------- arch/ia64/kernel/cpufreq/acpi-processor.c | 67 +++++++++++++++++ arch/x86_64/kernel/acpi/Makefile | 5 ++ arch/x86_64/kernel/acpi/processor.c | 72 ++++++++++++++++++ drivers/acpi/processor_core.c | 28 +++---- drivers/acpi/processor_idle.c | 2 - drivers/acpi/processor_perflib.c | 2 - include/acpi/pdc_intel.h | 4 +- include/acpi/processor.h | 22 ++---- include/asm-i386/acpi.h | 2 +- 16 files changed, 243 insertions(+), 231 deletions(-) create mode 100644 arch/i386/kernel/acpi/processor.c create mode 100644 arch/ia64/kernel/cpufreq/acpi-processor.c create mode 100644 arch/x86_64/kernel/acpi/processor.c diff --git a/arch/i386/kernel/acpi/Makefile b/arch/i386/kernel/acpi/Makefile index 267ca48e1b6..d51c7313cae 100644 --- a/arch/i386/kernel/acpi/Makefile +++ b/arch/i386/kernel/acpi/Makefile @@ -3,6 +3,6 @@ obj-$(CONFIG_X86_IO_APIC) += earlyquirk.o obj-$(CONFIG_ACPI_SLEEP) += sleep.o wakeup.o ifneq ($(CONFIG_ACPI_PROCESSOR),) -obj-y += cstate.o +obj-y += cstate.o processor.o endif diff --git a/arch/i386/kernel/acpi/cstate.c b/arch/i386/kernel/acpi/cstate.c index 4c3036ba65d..25db49ef177 100644 --- a/arch/i386/kernel/acpi/cstate.c +++ b/arch/i386/kernel/acpi/cstate.c @@ -14,64 +14,6 @@ #include #include -static void acpi_processor_power_init_intel_pdc(struct acpi_processor_power - *pow) -{ - struct acpi_object_list *obj_list; - union acpi_object *obj; - u32 *buf; - - /* allocate and initialize pdc.

The code has been optimized to simplify and eliminate duplicated code, CPU stack use has been decreased by optimizing function parameters and local variables, and naming conventions across the manager have been standardized for clarity and ease of maintenance (this includes function, parameter, variable, and struct/typedef names.) All Resource Manager dispatch and information tables have been moved to a single location for clarity and ease of maintenance. One new file was created, named "rsinfo.c". The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to guarantee that the argument is not evaluated twice, making them less prone to macro side-effects. However, since there exists the possibility of additional stack use if a particular compiler cannot optimize them (such as in the debug generation case), the original macros are optionally available. Note that some invocations of the return_VALUE macro may now cause size mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to eliminate these. (From Randy Dunlap) Implemented a new mechanism to enable debug tracing for individual control methods. A new external interface, acpi_debug_trace(), is provided to enable this mechanism. The intent is to allow the host OS to easily enable and disable tracing for problematic control methods. This interface can be easily exposed to a user or debugger interface if desired. See the file psxface.c for details. acpi_ut_callocate() will now return a valid pointer if a length of zero is specified - a length of one is used and a warning is issued. This matches the behavior of acpi_ut_allocate().

/* -- GitLab From 0897831bb54eb36fd9e2a22da7f0f64be1b20d09 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Fri, 21 Oct 2005 00:00:00 -0400 Subject: [PATCH 0016/1843] [ACPI] ACPICA 20051021 Implemented support for the EM64T and other x86_64 processors. This essentially entails recognizing that these processors support non-aligned memory transfers. Previously, all 64-bit processors were assumed to lack hardware support for non-aligned transfers. Completed conversion of the Resource Manager to nearly full table-driven operation. Specifically, the resource conversion code (convert AML to internal format and the reverse) and the debug code to dump internal resource descriptors are fully table-driven, reducing code and data size and improving maintainability. The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word on 64-bit processors instead of a fixed 32-bit word. (Alexey Starikovskiy) Implemented support within the resource conversion code for the Type-Specific byte within the various ACPI 3.0 *WordSpace macros. Fixed some issues within the resource conversion code for the type-specific flags for both Memory and I/O address resource descriptors. For Memory, implemented support for the MTP and TTP flags. For I/O, split the TRS and TTP flags into two separate fields.

The GPE initialization has been split into two parts in order to defer execution of the _PRW methods (Power Resources for Wake) until after the hardware is fully initialized and the SCI handler is installed. This allows the _PRW methods to access fields protected by the Global Lock. This will fix systems where a NO_GLOBAL_LOCK exception has been seen during initialization. Fixed a regression with the ConcatenateResTemplate() ASL operator introduced in the 20051021 release. Implemented support for "local" internal ACPI object types within the debugger "Object" command and the acpi_walk_namespace() external interfaces. These local types include RegionFields, BankFields, IndexFields, Alias, and reference objects. Moved common AML resource handling code into a new file, "utresrc.c". This code is shared by both the Resource Manager and the AML Debugger.

This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. This also fixed a related regression with the mechanism that detects and corrects methods that cannot properly handle reentrancy (related to the deployment of the new OwnerId mechanism.) Eliminated the pre-parsing of control methods (to detect errors) during table load. Related to the problem above, this was causing unwind issues if any errors occurred during the parse, and it seemed to be overkill. A table load should not be aborted if there are problems with any single control method, thus rendering this feature rather pointless. Fixed a problem with the new table-driven resource manager where an internal buffer overflow could occur for small resource templates. Implemented a new external interface, acpi_get_vendor_resource() This interface will find and return a vendor-defined resource descriptor within a _CRS or _PRS method via an ACPI 3.0 UUID match. (from Bjorn Helgaas) Removed the length limit (200) on string objects as per the upcoming ACPI 3.0A specification. This affects the following areas of the interpreter: 1) any implicit conversion of a Buffer to a String, 2) a String object result of the ASL Concatentate operator, 3) the String object result of the ASL ToString operator.

Objects are now created only during the execute phase, at the moment the namespace creation operator is encountered in the AML (Name, OperationRegion, CreateByteField, etc.) This should eliminate ALREADY_EXISTS exceptions seen on some machines where reentrant control methods are protected by an AML mutex. The mutex will now correctly block multiple threads from attempting to create the same object more than once. Increased the number of available Owner Ids for namespace object tracking from 32 to 255. This should eliminate the OWNER_ID_LIMIT exceptions seen on some machines with a large number of ACPI tables (either static or dynamic). Enhanced the namespace dump routine to output the owner ID for each namespace object.

A null object is inserted in the package when a named reference cannot be located in the current namespace. Enabled via the interpreter slack flag which Linux has enabled by default (acpi=strict to disable slack). This should eliminate AE_NOT_FOUND exceptions seen on machines that contain such code. Implemented an optimization to the initialization sequence that can improve boot time. During ACPI device initialization, the _STA method is now run if and only if the _INI method exists. The _STA method is used to determine if the device is present; An _INI can only be run if _STA returns present, but it is a waste of time to run the _STA method if the _INI does not exist. (Prototype and assistance from Dong Wei) Implemented use of the C99 uintptr_t for the pointer casting macros if it is available in the current compiler. Otherwise, the default (void *) cast is used as before. Fixed some possible memory leaks found within the execution path of the Break, Continue, If, and CreateField operators. (Valery Podrezov) Fixed a problem introduced in the 20051202 release where an exception is generated during method execution if a control method attempts to declare another method.

So we have to pad syscall table with sys_ni_syscall and that's where the trouble begins. .rept pseudo-op wants a constant expression for number of repetitions and subtraction of two labels (before and after syscall table) doesn't always get simplified to constant early enough for .rept. If labels end up in different frags, we lose. And while the frag size is large enough (slightly below 4Kb), the syscall table is about 1/3 of that. We used to get away with that, but the recent changes had been enough to trigger the breakage. Proper fix is simple: have a macro (CALL(x)) to populate the table instead of using explicit .long x and the first time we include calls.S have it defined to .equ NR_syscalls,NR_syscalls+1. Then we can find the proper amount of padding on the first inclusion simply by looking at NR_syscalls at that time. And that will be constant, no matter what. Moreover, the same trick kills the need of having an estimate of padded NR_syscalls - it will be calculated for free at the same time.

At SuSE's suggestion, enabled all error messages without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros, respectively. This preserves all error and warning messages in the non-debug version of the ACPICA code (this has been referred to as the "debug lite" option.) Over 200 cases were converted to create a total of over 380 error/warning messages across the ACPICA code. This increases the code and data size of the default non-debug version by about 13K. Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages. The size of the debug version remains about the same.

The main reason was that /dev/null was used as output to gcc in the check-lxdialog.sh script and gcc did some strange things with the output file; in this case /dev/null when it errorred out. Following patch implements a suggestion from Bryan O'Sullivan to use gcc -print-file-name=libxxx.so. Also the Makefile is adjusted to not resolve value of HOST_EXTRACFLAGS and HOST_LOADLIBES until they are actually used.

At the end of the serial console print we force enable the tx int in case we clobbered the tx interrupt status racing between the console and tty output. That way the extra tx interrupt causes the transmit path to restart not hang. It also makes the serial console printk use the FIFO. This is neccessary because some remote management devices fake serial console with FIFO and are confused into sending one packet per character over ethernet when we stall rather than filling the FIFO. In order to preserve existing reliability semantics the function waits for the serial queue to completely empty before returning. Both of these problems were identified by a Red Hat partner.

However, now the list in intel8x0.c contains a duplicate, since the HP nx6110 and nc6120 have identical subdevice ids. This was introduced in -mm1 by the following patch: add-new-quirk-for-devices-with-mute-leds-and-separate-headphone-volume.patch Since the HP nx6110 and nc6120 are almost identical, both entries should really be combined, as in the following patch.

The pcnet32 driver looks for the PCI ethernet class before grabbing the hardware, but the current trident driver does not check against the PCI audio class. This allows the trident driver to claim the pcnet32 hardware. This patch prevents that. Per Jiri Slaby's request, I changed the trident driver to use PCI_DEVICE macro and PCI ID #defines. This patch is untested on Trident 4DWAVE_DX hardware, but has been tested on pcnet32 hardware.

Looking closely at the code, I found some possible issues in the way we setup the MDIO lines during suspend along with slight divergences from what Darwin does when resetting it that may explain the problem. That patch change these and the problem appear to be gone for me at least... I also fixed an mdelay -> msleep while I was at it to the pmac feature code that is called when toggling the PHY reset line since sungem doesn't call it in an atomic context anymore.

The old behavior falls back to the compiled-in default if the requested one is not registered at boot time. This patch dynamically evaluates which default to use, and emits a suitable error message when the requested scheduler is not available. It also does the 'as' -> 'anticipatory' conversion before elevator registration, which along with a modified registration function, allows it to correctly indicate which default scheduler is in use. Tested for a range of boot options on 2.6.16-rc1-mm2.

The driver can typically detect port-loss during an interrupt context (i.e. via interrogation of a status IOCB's completion status [CS_PORT_LOGGED_OUT]. Due to the calling requirements of the fc_rport APIs, the driver would defer removal of the device to the default workqueue. If the work-item was preceded by an event which caused the port to obtain visibility (relogin successful, target re-logged into the topology), deferred removal could inadvertently drop the rport. The code also no longer defers removal via the default workqueue, instead opting for use of the driver's own DPC thread.

A target can LOGO an initiator at any time (i.e. during I/O, due to a controller hicup, or as a simple authentication mechanism after an initial CDB command), when this occurs, the driver attempts to relogin (PLOGI) to the device via the DPC thread. Add code to make the appropriate upcall to the FC transport layer (fc_remote_port_add()) upon successful completion of the PLOGI.

The SG_IO interface allows userspace to specify the CDB length. This is now ignored in scsi_execute_async and it is guessed using the COMMAND_SIZE macro, which is not always correct, particularly for vendor specific commands. This patch adds a cmd_len parameter to the scsi_execute_async interface to allow the caller to specify the length of the CDB.

Enabling this quirk has the effect of clamping all ATA commands to no more than 15 sectors. The intended use of this quirk is to stop the controller from generating FIS's of unusual size ("but Wesley, what about the FOUS's?"), which in turn works around problems in a of hard drives. One side effect of this quirk is greatly decreased performance. Users often enable the mod15write quirk to fix various system, power, chip, and/or driver problems. For a few rare problematic cases, enabling this has cured lockups or data corruption. Rather than add bogus listings to the mod15write quirk list (I get a patch every month doing such), we add a 'slow_down' module parameter. This allows users to employ a performance sledgehammer in the hopes of curing a problem. It defaults to off (0), of course. --- drivers/scsi/sata_sil.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/drivers/scsi/sata_sil.c b/drivers/scsi/sata_sil.c index b017f85e6d6..17f74d3c10e 100644 --- a/drivers/scsi/sata_sil.c +++ b/drivers/scsi/sata_sil.c @@ -231,6 +231,10 @@ MODULE_LICENSE("GPL"); MODULE_DEVICE_TABLE(pci, sil_pci_tbl); MODULE_VERSION(DRV_VERSION); +static int slow_down = 0; +module_param(slow_down, int, 0444); +MODULE_PARM_DESC(slow_down, "Sledgehammer used to work around random problems, by limiting commands to 15 sectors (0=off, 1=on)"); + static unsigned char sil_get_device_cache_line(struct pci_dev *pdev) { @@ -354,8 +358,10 @@ static void sil_dev_config(struct ata_port *ap, struct ata_device *dev) } /* limit requests to 15 sectors */ - if ((ap->flags & SIL_FLAG_MOD15WRITE) && (quirks & SIL_QUIRK_MOD15WRITE)) { - printk(KERN_INFO "ata%u(%u): applying Seagate errata fix\n", + if (slow_down || + ((ap->flags & SIL_FLAG_MOD15WRITE) && + (quirks & SIL_QUIRK_MOD15WRITE))) { + printk(KERN_INFO "ata%u(%u): applying Seagate errata fix (mod15write workaround)\n", ap->id, dev->devno); ap->host->max_sectors = 15; ap->host->hostt->max_sectors = 15; -- GitLab From eb9bdaa3f3b9d30d09bcad47037216aa39639b8e Mon Sep 17 00:00:00 2001 From: Steve French Date: Fri, 27 Jan 2006 15:11:47 -0800 Subject: [PATCH 0218/1843] Signed-off-by: Steve French --- fs/cifs/file.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/fs/cifs/file.c b/fs/cifs/file.c index 77c990f0cb9..d17c97d07c8 100644 --- a/fs/cifs/file.c +++ b/fs/cifs/file.c @@ -1190,7 +1190,6 @@ retry: /* BB what if continued retry is requested via mount flags? */ set_bit(AS_EIO, &mapping->flags); - SetPageError(page); } else { cifs_stats_bytes_written(cifs_sb->tcon, bytes_written); @@ -1198,6 +1197,13 @@ retry: } for (i = 0; i < n_iov; i++) { page = pvec.pages[first + i]; + /* Should we also set page error on + success rc but too little data written? */ + /* BB investigate retry logic on temporary + server crash cases and how recovery works + when page marked as error */ + if(rc) + SetPageError(page); kunmap(page); unlock_page(page); page_cache_release(page); -- GitLab From 1877c9ea66a29563987f22d0a86c66f438a87ce2 Mon Sep 17 00:00:00 2001 From: Steve French Date: Fri, 27 Jan 2006 18:36:11 -0800 Subject: [PATCH 0219/1843] [CIFS] Remove compiler warning Signed-off-by: Steve French --- fs/cifs/connect.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/fs/cifs/connect.c b/fs/cifs/connect.c index eae306fa24b..e488603fb1e 100644 --- a/fs/cifs/connect.c +++ b/fs/cifs/connect.c @@ -1786,7 +1786,8 @@ cifs_mount(struct super_block *sb, struct cifs_sb_info *cifs_sb, cifs_sb->wsize = volume_info.wsize; else cifs_sb->wsize = - min(PAGEVEC_SIZE * PAGE_CACHE_SIZE, 127*1024); + min_t(const int, PAGEVEC_SIZE * PAGE_CACHE_SIZE, + 127*1024); /* old default of CIFSMaxBufSize was too small now that SMB Write2 can send multiple pages in kvec.

As a result we see messages like ib_mthca 0000:04:00.0: HW2SW_CQ failed (-4) In this case, hardware could access the resource after the memory has been freed, possibly causing memory corruption. A simple solution is to replace down_interruptible() by down() in command interface activation. Signed-off-by: Michael S.

This support is in addition to the previously implemented unresolved reference support within the AML parser. If the interpreter slack mode is enabled (true on Linux unless acpi=strict), these unresolved references will be passed through to the caller as a NULL package entry. http://bugzilla.kernel.org/show_bug.cgi?id=5741 Implemented and deployed new macros and functions for error and warning messages across the subsystem. These macros are simpler and generate less code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION, ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. Implemented the acpi_cpu_flags type to simplify host OS integration of the Acquire/Release Lock OSL interfaces. Suggested by Steven Rostedt and Andrew Morton. Fixed a problem where Alias ASL operators are sometimes not correctly resolved. causing AE_AML_INTERNAL http://bugzilla.kernel.org/show_bug.cgi?id=5189 http://bugzilla.kernel.org/show_bug.cgi?id=5674 Fixed several problems with the implementation of the ConcatenateResTemplate ASL operator. As per the ACPI specification, zero length buffers are now treated as a single EndTag. One-length buffers always cause a fatal exception. Non-zero length buffers that do not end with a full 2-byte EndTag cause a fatal exception. Fixed a possible structure overwrite in the AcpiGetObjectInfo external interface.

One notable change: the "early handoff" version always enabled an SMI IRQ ... and did so even if the pre-Linux code said it was not using EHCI (and not expecting EHCI SMIs). Looks like a goof in a workaround for some unknown BIOS version. This merged version only forcibly enables those IRQs when pre-Linux code says it's using EHCI. And now it always forces them off "just in case".

Then, if URB fails to complete, ub hangs until the device is unplugged. This does not happen often, becase we only allow one SCSI command per block device, but does happen (on multi-LUN devices, for example). The fix is to stop timer only when we actually going to change the state. The nicest code would be to have the timer stopped in URB callback, but this is impossible, because it can be called from inside a timer, through the urb_unlink. Then we get BUG in timer.c:cascade(). So, we do it a little dirtier.

It has been +designed to run properly on SMP systems as well. + +The latest version of the ET61X[12]51 driver can be found at the following URL: +http://www.linux-projects.org/ + +Some of the features of the driver are: + +- full compliance with the Video4Linux2 API (see also "Notes for V4L2 + application developers" paragraph); +- available mmap or read/poll methods for video streaming through isochronous + data transfers; +- automatic detection of image sensor; +- support for any window resolutions and optional panning within the maximum + pixel area of image sensor; +- image downscaling with arbitrary scaling factors from 1 and 2 in both + directions (see "Notes for V4L2 application developers" paragraph); +- two different video formats for uncompressed or compressed data in low or + high compression quality (see also "Notes for V4L2 application developers" + paragraph); +- full support for the capabilities of every possible image sensors that can + be connected to the ET61X[12]51 bridges, including, for istance, red, green, + blue and global gain adjustments and exposure control (see "Supported + devices" paragraph for details); +- use of default color settings for sunlight conditions; +- dynamic I/O interface for both ET61X[12]51 and image sensor control (see + "Optional device control through 'sysfs'" paragraph); +- dynamic driver control thanks to various module parameters (see "Module + parameters" paragraph); +- up to 64 cameras can be handled at the same time; they can be connected and + disconnected from the host many times without turning off the computer, if + the system supports hotplugging; +- no known bugs. + + +5. Module dependencies +====================== +For it to work properly, the driver needs kernel support for Video4Linux and +USB. + +The following options of the kernel configuration file must be enabled and +corresponding modules must be compiled: + + # Multimedia devices + # + CONFIG_VIDEO_DEV=m + +To enable advanced debugging functionality on the device through /sysfs: + + # Multimedia devices + # + CONFIG_VIDEO_ADV_DEBUG=y + + # USB support + # + CONFIG_USB=m + +In addition, depending on the hardware being used, the modules below are +necessary: + + # USB Host Controller Drivers + # + CONFIG_USB_EHCI_HCD=m + CONFIG_USB_UHCI_HCD=m + CONFIG_USB_OHCI_HCD=m + +And finally: + + # USB Multimedia devices + # + CONFIG_USB_ET61X251=m + + +6. Module loading +================= +To use the driver, it is necessary to load the "et61x251" module into memory +after every other module required: "videodev", "usbcore" and, depending on +the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". + +Loading can be done as shown below: + + [root@localhost home]# modprobe et61x251 + +At this point the devices should be recognized. You can invoke "dmesg" to +analyze kernel messages and verify that the loading process has gone well: + + [user@localhost home]$ dmesg + + +7. Module parameters +==================== +Module parameters are listed below: +------------------------------------------------------------------------------- +Name: video_nr +Type: short array (min = 0, max = 64) +Syntax: <-1|n[,...]> +Description: Specify V4L2 minor mode number: + -1 = use next available + n = use minor number n + You can specify up to 64 cameras this way. + For example: + video_nr=-1,2,-1 would assign minor number 2 to the second + registered camera and use auto for the first one and for every + other camera. +Default: -1 +------------------------------------------------------------------------------- +Name: force_munmap +Type: bool array (min = 0, max = 64) +Syntax: <0|1[,...]> +Description: Force the application to unmap previously mapped buffer memory + before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not + all the applications support this feature. This parameter is + specific for each detected camera. + 0 = do not force memory unmapping + 1 = force memory unmapping (save memory) +Default: 0 +------------------------------------------------------------------------------- +Name: debug +Type: ushort +Syntax: +Description: Debugging information level, from 0 to 3: + 0 = none (use carefully) + 1 = critical errors + 2 = significant informations + 3 = more verbose messages + Level 3 is useful for testing only, when only one device + is used at the same time. It also shows some more informations + about the hardware being detected. This module parameter can be + changed at runtime thanks to the /sys filesystem interface. +Default: 2 +------------------------------------------------------------------------------- + + +8. Optional device control through "sysfs" +========================================== +If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, +it is possible to read and write both the ET61X[12]51 and the image sensor +registers by using the "sysfs" filesystem interface. + +There are four files in the /sys/class/video4linux/videoX directory for each +registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files +control the ET61X[12]51 bridge, while the other two control the sensor chip. +"reg" and "i2c_reg" hold the values of the current register index where the +following reading/writing operations are addressed at through "val" and +"i2c_val". Their use is not intended for end-users, unless you know what you +are doing. Remember that you must be logged in as root before writing to them. + +As an example, suppose we were to want to read the value contained in the +register number 1 of the sensor register table - which is usually the product +identifier - of the camera registered as "/dev/video0": + + [root@localhost #] cd /sys/class/video4linux/video0 + [root@localhost #] echo 1 > i2c_reg + [root@localhost #] cat i2c_val + +Note that if the sensor registers can not be read, "cat" will fail. +To avoid race conditions, all the I/O accesses to the files are serialized. + + +9. Supported devices +==================== +None of the names of the companies as well as their products will be mentioned +here. They have never collaborated with the author, so no advertising. + +From the point of view of a driver, what unambiguously identify a device are +its vendor and product USB identifiers. Below is a list of known identifiers of +devices mounting the ET61X[12]51 PC camera controllers: + +Vendor ID Product ID +--------- ---------- +0x102c 0x6151 +0x102c 0x6251 +0x102c 0x6253 +0x102c 0x6254 +0x102c 0x6255 +0x102c 0x6256 +0x102c 0x6257 +0x102c 0x6258 +0x102c 0x6259 +0x102c 0x625a +0x102c 0x625b +0x102c 0x625c +0x102c 0x625d +0x102c 0x625e +0x102c 0x625f +0x102c 0x6260 +0x102c 0x6261 +0x102c 0x6262 +0x102c 0x6263 +0x102c 0x6264 +0x102c 0x6265 +0x102c 0x6266 +0x102c 0x6267 +0x102c 0x6268 +0x102c 0x6269 + +The following image sensors are supported: + +Model Manufacturer +----- ------------ +TAS5130D1B Taiwan Advanced Sensor Corporation + +All the available control settings of each image sensor are supported through +the V4L2 interface. + + +10. Notes for V4L2 application developers +======================================== +This driver follows the V4L2 API specifications. In particular, it enforces two +rules: + +- exactly one I/O method, either "mmap" or "read", is associated with each +file descriptor. Once it is selected, the application must close and reopen the +device to switch to the other I/O method; + +- although it is not mandatory, previously mapped buffer memory should always +be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. +The same number of buffers as before will be allocated again to match the size +of the new video frames, so you have to map the buffers again before any I/O +attempts on them. + +Consistently with the hardware limits, this driver also supports image +downscaling with arbitrary scaling factors from 1 and 2 in both directions. +However, the V4L2 API specifications don't correctly define how the scaling +factor can be chosen arbitrarily by the "negotiation" of the "source" and +"target" rectangles. To work around this flaw, we have added the convention +that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the +scaling factor is restored to 1. + +This driver supports two different video formats: the first one is the "8-bit +Sequential Bayer" format and can be used to obtain uncompressed video data +from the device through the current I/O method, while the second one provides +"raw" compressed video data (without frame headers not related to the +compressed data). The current compression quality may vary from 0 to 1 and can +be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP +V4L2 ioctl's. + + +11.

This signals a socket shutdown, letting the socket user know that the game is up. I wrote this patch because of reports that pppd would keep connections open forever when the modem is disconnected. This patch does not fix that problem, but it's a step in the right direction. It doesn't help because the pppoatm module doesn't yet monitor state changes on the ATM socket, so simply never realises that the ATM connection has gone down (meaning it doesn't tell the ppp layer). But at least there is a socket state change now. Unfortunately this patch may create problems for those rare users like me who use routed IP or some other non-ppp connection method that goes via the ATM ARP daemon: the daemon is buggy, and with this patch will crash when the modem is disconnected. Users with a buggy atmarpd can simply restart it after disconnecting the modem.

Since there is some danger that users may not notice this change, the parameters are renamed to rcv_buf_bytes etc. The transmit buffer needs to be a multiple of the ATM cell size in length, while the receive buffer should be a multiple of the endpoint maxpacket size (this wasn't enforced before, which causes trouble with isochronous transfers), so enforce these restrictions. Now that the usbatm probe method inspects the endpoint maxpacket size, minidriver bind routines need to set the correct alternate setting for the interface in their bind routine. This is the reason for the speedtch changes.

While use of isoc transfer should still be considered experimental, it now works well enough to let users turn it on. Minidrivers signal to the core that they want to use isoc transfer by setting the new UDSL_USE_ISOC flag. The speedtch minidriver gets a new module parameter enable_isoc (defaults to false), plus some logic that checks for the existence of an isoc receive endpoint (not all speedtouch modems have one).

A new module parameter is added to select iso mode. It is set to iso by default because bulk mode doesn't work well at high speed rate (>3 Mbps for upload). We use UDSL_IGNORE_EILSEQ flags because ADI firmware doesn't reply to ISO IN when it has nothing to send [1]. [1] from cypress datasheet : The ISOSEND0 Bit (bit 7 in the USBPAIR Register) is used when the EZ-USB FX chip receives an isochronous IN token while the IN FIFO is empty. If ISOSEND0=0 (the default value), the USB core does not respond to the IN token. If ISOSEND0=1, the USB core sends a zero-length data packet in response to the IN token.

The current code attempts to add iospace for an entire root bus, which is inappropriate, and silently fails. When a pci device tries to use the iospace, a page fault is taken, as the iospace had not been mapped, and of course the page fault cannot be resolved. This only occurs for PCI adapters using pio, which may be why it hadn't been seen earlier (this seems to have been broken for a while).

With sshfs a 1.5 to 4 times slowdown can be measured. There's also a need for userspace filesystems to know whether asynchronous reads are supported by the kernel or not. To achive these, negotiate in the INIT request whether async reads will be used and the maximum readahead value. Update interface version to 7.6 If userspace uses a version earlier than 7.6, then disable async reads, and set maximum readahead value to the maximum read size, as done in previous versions.

It also triggers a message "Driver 'ide-scsi' needs updating - please use bus_type methods" from the driver core. The IDE core in 2.6.16-rc1 changed the location of an IDE driver's ->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t struct not in the gen_driver sub-struct. drivers/ide/ was updated for this change but ide-scsi.c wasn't.

That makes the BE machines keep the bitmap internally in LE order - it does mean you can't use any other type of operations on the bitmap words but that looks to be OK in this instance. The efficiency tradeoff is very minimal as you would expect for something that ext2 uses. This allows us to remove bits_to_core(), bits_to_disk() and log->disk_bits. Also increment the mirror log disk version transparently to avoid sharing with older kernels that suffered from the 64-bit BE bug.

The signal is queued. After releasing the posix-timer lock and before returning to hrtimer_run_queue CPU0 gets interrupted. CPU1 delivers the queued signal and rearms the timer. CPU0 comes back to hrtimer_run_queue and sets the timer state to expired. The next modification of the timer can result in an oops, because the state information is wrong. Keep track of state = RUNNING and check if the state has been in the return path of hrtimer_run_queue. In case the state has been changed, ignore a restart request and do not touch the state variable.

The +legacy iSeries platform breaks those rules as it predates this scheme, +but no new board support will be accepted in the main tree that +doesn't follows them properly. In addition, since the advent of the +arch/powerpc merged architecture for ppc32 and ppc64, new 32-bit +platforms and 32-bit platforms which move into arch/powerpc will be +required to use these rules as well. + +The main requirement that will be defined in more detail below is +the presence of a device-tree whose format is defined after Open +Firmware specification. However, in order to make life easier +to embedded board vendors, the kernel doesn't require the device-tree +to represent every device in the system and only requires some nodes +and properties to be present. This will be described in detail in +section III, but, for example, the kernel does not require you to +create a node for every PCI device in the system. It is a requirement +to have a node for PCI host bridges in order to provide interrupt +routing informations and memory/IO ranges, among others. It is also +recommended to define nodes for on chip devices and other busses that +don't specifically fit in an existing OF specification. This creates a +great flexibility in the way the kernel can then probe those and match +drivers to device, without having to hard code all sorts of tables. It +also makes it more flexible for board vendors to do minor hardware +upgrades without significantly impacting the kernel code or cluttering +it with special cases. + + +1) Entry point for arch/powerpc +------------------------------- + + There is one and one single entry point to the kernel, at the start + of the kernel image. That entry point supports two calling + conventions: + + a) Boot from Open Firmware. If your firmware is compatible + with Open Firmware (IEEE 1275) or provides an OF compatible + client interface API (support for "interpret" callback of + forth words isn't required), you can enter the kernel with: + + r5 : OF callback pointer as defined by IEEE 1275 + bindings to powerpc. Only the 32 bit client interface + is currently supported + + r3, r4 : address & length of an initrd if any or 0 + + The MMU is either on or off; the kernel will run the + trampoline located in arch/powerpc/kernel/prom_init.c to + extract the device-tree and other information from open + firmware and build a flattened device-tree as described + in b). prom_init() will then re-enter the kernel using + the second method. This trampoline code runs in the + context of the firmware, which is supposed to handle all + exceptions during that time. + + b) Direct entry with a flattened device-tree block. This entry + point is called by a) after the OF trampoline and can also be + called directly by a bootloader that does not support the Open + Firmware client interface. It is also used by "kexec" to + implement "hot" booting of a new kernel from a previous + running one. This method is what I will describe in more + details in this document, as method a) is simply standard Open + Firmware, and thus should be implemented according to the + various standard documents defining it and its binding to the + PowerPC platform. The entry point definition then becomes: + + r3 : physical pointer to the device-tree block + (defined in chapter II) in RAM + + r4 : physical pointer to the kernel itself. This is + used by the assembly code to properly disable the MMU + in case you are entering the kernel with MMU enabled + and a non-1:1 mapping. + + r5 : NULL (as to differenciate with method a) + + Note about SMP entry: Either your firmware puts your other + CPUs in some sleep loop or spin loop in ROM where you can get + them out via a soft reset or some other means, in which case + you don't need to care, or you'll have to enter the kernel + with all CPUs. The way to do that with method b) will be + described in a later revision of this document. + + +2) Board support +---------------- + +64-bit kernels: + + Board supports (platforms) are not exclusive config options. An + arbitrary set of board supports can be built in a single kernel + image. The kernel will "know" what set of functions to use for a + given platform based on the content of the device-tree. Thus, you + should: + + a) add your platform support as a _boolean_ option in + arch/powerpc/Kconfig, following the example of PPC_PSERIES, + PPC_PMAC and PPC_MAPLE. The later is probably a good + example of a board support to start from. + + b) create your main platform file as + "arch/powerpc/platforms/myplatform/myboard_setup.c" and add it + to the Makefile under the condition of your CONFIG_ + option. This file will define a structure of type "ppc_md" + containing the various callbacks that the generic code will + use to get to your platform specific code + + c) Add a reference to your "ppc_md" structure in the + "machines" table in arch/powerpc/kernel/setup_64.c if you are + a 64-bit platform. + + d) request and get assigned a platform number (see PLATFORM_* + constants in include/asm-powerpc/processor.h + +32-bit embedded kernels: + + Currently, board support is essentially an exclusive config option. + The kernel is configured for a single platform. Part of the reason + for this is to keep kernels on embedded systems small and efficient; + part of this is due to the fact the code is already that way. In the + future, a kernel may support multiple platforms, but only if the + platforms feature the same core architectire. A single kernel build + cannot support both configurations with Book E and configurations + with classic Powerpc architectures. + + 32-bit embedded platforms that are moved into arch/powerpc using a + flattened device tree should adopt the merged tree practice of + setting ppc_md up dynamically, even though the kernel is currently + built with support for only a single platform at a time. This allows + unification of the setup code, and will make it easier to go to a + multiple-platform-support model in the future. + +NOTE: I believe the above will be true once Ben's done with the merge +of the boot sequences.... someone speak up if this is wrong! + + To add a 32-bit embedded platform support, follow the instructions + for 64-bit platforms above, with the exception that the Kconfig + option should be set up such that the kernel builds exclusively for + the platform selected. The processor type for the platform should + enable another config option to select the specific board + supported. + +NOTE: If ben doesn't merge the setup files, may need to change this to +point to setup_32.c + + + I will describe later the boot process and various callbacks that + your platform should implement. + + +II - The DT block format +======================== + + +This chapter defines the actual format of the flattened device-tree +passed to the kernel. The actual content of it and kernel requirements +are described later. You can find example of code manipulating that +format in various places, including arch/powerpc/kernel/prom_init.c +which will generate a flattened device-tree from the Open Firmware +representation, or the fs2dt utility which is part of the kexec tools +which will generate one from a filesystem representation. It is +expected that a bootloader like uboot provides a bit more support, +that will be discussed later as well. + +Note: The block has to be in main memory. It has to be accessible in +both real mode and virtual mode with no mapping other than main +memory. If you are writing a simple flash bootloader, it should copy +the block to RAM before passing it to the kernel. + + +1) Header +--------- + + The kernel is entered with r3 pointing to an area of memory that is + roughtly described in include/asm-powerpc/prom.h by the structure + boot_param_header: + +struct boot_param_header { + u32 magic; /* magic word OF_DT_HEADER */ + u32 totalsize; /* total size of DT block */ + u32 off_dt_struct; /* offset to structure */ + u32 off_dt_strings; /* offset to strings */ + u32 off_mem_rsvmap; /* offset to memory reserve map +*/ + u32 version; /* format version */ + u32 last_comp_version; /* last compatible version */ + + /* version 2 fields below */ + u32 boot_cpuid_phys; /* Which physical CPU id we're + booting on */ + /* version 3 fields below */ + u32 size_dt_strings; /* size of the strings block */ +}; + + Along with the constants: + +/* Definitions used by the flattened device tree */ +#define OF_DT_HEADER 0xd00dfeed /* 4: version, + 4: total size */ +#define OF_DT_BEGIN_NODE 0x1 /* Start node: full name +*/ +#define OF_DT_END_NODE 0x2 /* End node */ +#define OF_DT_PROP 0x3 /* Property: name off, + size, content */ +#define OF_DT_END 0x9 + + All values in this header are in big endian format, the various + fields in this header are defined more precisely below. All + "offset" values are in bytes from the start of the header; that is + from the value of r3. + + - magic + + This is a magic value that "marks" the beginning of the + device-tree block header. It contains the value 0xd00dfeed and is + defined by the constant OF_DT_HEADER + + - totalsize + + This is the total size of the DT block including the header. The + "DT" block should enclose all data structures defined in this + chapter (who are pointed to by offsets in this header). That is, + the device-tree structure, strings, and the memory reserve map. + + - off_dt_struct + + This is an offset from the beginning of the header to the start + of the "structure" part the device tree. (see 2) device tree) + + - off_dt_strings + + This is an offset from the beginning of the header to the start + of the "strings" part of the device-tree + + - off_mem_rsvmap + + This is an offset from the beginning of the header to the start + of the reserved memory map. This map is a list of pairs of 64 + bit integers. Each pair is a physical address and a size. The + + list is terminated by an entry of size 0. This map provides the + kernel with a list of physical memory areas that are "reserved" + and thus not to be used for memory allocations, especially during + early initialization. The kernel needs to allocate memory during + boot for things like un-flattening the device-tree, allocating an + MMU hash table, etc... Those allocations must be done in such a + way to avoid overriding critical things like, on Open Firmware + capable machines, the RTAS instance, or on some pSeries, the TCE + tables used for the iommu. Typically, the reserve map should + contain _at least_ this DT block itself (header,total_size). If + you are passing an initrd to the kernel, you should reserve it as + well. You do not need to reserve the kernel image itself. The map + should be 64 bit aligned. + + - version + + This is the version of this structure. Version 1 stops + here. Version 2 adds an additional field boot_cpuid_phys. + Version 3 adds the size of the strings block, allowing the kernel + to reallocate it easily at boot and free up the unused flattened + structure after expansion. Version 16 introduces a new more + "compact" format for the tree itself that is however not backward + compatible. You should always generate a structure of the highest + version defined at the time of your implementation. Currently + that is version 16, unless you explicitely aim at being backward + compatible. + + - last_comp_version + + Last compatible version. This indicates down to what version of + the DT block you are backward compatible. For example, version 2 + is backward compatible with version 1 (that is, a kernel build + for version 1 will be able to boot with a version 2 format). You + should put a 1 in this field if you generate a device tree of + version 1 to 3, or 0x10 if you generate a tree of version 0x10 + using the new unit name format. + + - boot_cpuid_phys + + This field only exist on version 2 headers. It indicate which + physical CPU ID is calling the kernel entry point. This is used, + among others, by kexec. If you are on an SMP system, this value + should match the content of the "reg" property of the CPU node in + the device-tree corresponding to the CPU calling the kernel entry + point (see further chapters for more informations on the required + device-tree contents) + + + So the typical layout of a DT block (though the various parts don't + need to be in that order) looks like this (addresses go from top to + bottom): + + + ------------------------------ + r3 -> | struct boot_param_header | + ------------------------------ + | (alignment gap) (*) | + ------------------------------ + | memory reserve map | + ------------------------------ + | (alignment gap) | + ------------------------------ + | | + | device-tree structure | + | | + ------------------------------ + | (alignment gap) | + ------------------------------ + | | + | device-tree strings | + | | + -----> ------------------------------ + | + | + --- (r3 + totalsize) + + (*) The alignment gaps are not necessarily present; their presence + and size are dependent on the various alignment requirements of + the individual data blocks. + + +2) Device tree generalities +--------------------------- + +This device-tree itself is separated in two different blocks, a +structure block and a strings block. Both need to be aligned to a 4 +byte boundary. + +First, let's quickly describe the device-tree concept before detailing +the storage format. This chapter does _not_ describe the detail of the +required types of nodes & properties for the kernel, this is done +later in chapter III. + +The device-tree layout is strongly inherited from the definition of +the Open Firmware IEEE 1275 device-tree. It's basically a tree of +nodes, each node having two or more named properties. A property can +have a value or not. + +It is a tree, so each node has one and only one parent except for the +root node who has no parent. + +A node has 2 names. The actual node name is generally contained in a +property of type "name" in the node property list whose value is a +zero terminated string and is mandatory for version 1 to 3 of the +format definition (as it is in Open Firmware). Version 0x10 makes it +optional as it can generate it from the unit name defined below. + +There is also a "unit name" that is used to differenciate nodes with +the same name at the same level, it is usually made of the node +name's, the "@" sign, and a "unit address", which definition is +specific to the bus type the node sits on. + +The unit name doesn't exist as a property per-se but is included in +the device-tree structure. It is typically used to represent "path" in +the device-tree. More details about the actual format of these will be +below. + +The kernel powerpc generic code does not make any formal use of the +unit address (though some board support code may do) so the only real +requirement here for the unit address is to ensure uniqueness of +the node unit name at a given level of the tree. Nodes with no notion +of address and no possible sibling of the same name (like /memory or +/cpus) may omit the unit address in the context of this specification, +or use the "@0" default unit address. The unit name is used to define +a node "full path", which is the concatenation of all parent node +unit names separated with "/". + +The root node doesn't have a defined name, and isn't required to have +a name property either if you are using version 3 or earlier of the +format. It also has no unit address (no @ symbol followed by a unit +address). The root node unit name is thus an empty string. The full +path to the root node is "/". + +Every node which actually represents an actual device (that is, a node +which isn't only a virtual "container" for more nodes, like "/cpus" +is) is also required to have a "device_type" property indicating the +type of node . + +Finally, every node that can be referenced from a property in another +node is required to have a "linux,phandle" property. Real open +firmware implementations provide a unique "phandle" value for every +node that the "prom_init()" trampoline code turns into +"linux,phandle" properties. However, this is made optional if the +flattened device tree is used directly. An example of a node +referencing another node via "phandle" is when laying out the +interrupt tree which will be described in a further version of this +document. + +This "linux, phandle" property is a 32 bit value that uniquely +identifies a node. You are free to use whatever values or system of +values, internal pointers, or whatever to generate these, the only +requirement is that every node for which you provide that property has +a unique value for it. + +Here is an example of a simple device-tree. In this example, an "o" +designates a node followed by the node unit name. Properties are +presented with their name followed by their content. "content" +represents an ASCII string (zero terminated) value, while +represents a 32 bit hexadecimal value. The various nodes in this +example will be discussed in a later chapter. At this point, it is +only meant to give you a idea of what a device-tree looks like. I have +purposefully kept the "name" and "linux,phandle" properties which +aren't necessary in order to give you a better idea of what the tree +looks like in practice. + + / o device-tree + |- name = "device-tree" + |- model = "MyBoardName" + |- compatible = "MyBoardFamilyName" + |- #address-cells = <2> + |- #size-cells = <2> + |- linux,phandle = <0> + | + o cpus + | | - name = "cpus" + | | - linux,phandle = <1> + | | - #address-cells = <1> + | | - #size-cells = <0> + | | + | o PowerPC,970@0 + | |- name = "PowerPC,970" + | |- device_type = "cpu" + | |- reg = <0> + | |- clock-frequency = <5f5e1000> + | |- linux,boot-cpu + | |- linux,phandle = <2> + | + o memory@0 + | |- name = "memory" + | |- device_type = "memory" + | |- reg = <00000000 00000000 00000000 20000000> + | |- linux,phandle = <3> + | + o chosen + |- name = "chosen" + |- bootargs = "root=/dev/sda2" + |- linux,platform = <00000600> + |- linux,phandle = <4> + +This tree is almost a minimal tree. It pretty much contains the +minimal set of required nodes and properties to boot a linux kernel; +that is, some basic model informations at the root, the CPUs, and the +physical memory layout. It also includes misc information passed +through /chosen, like in this example, the platform type (mandatory) +and the kernel command line arguments (optional). + +The /cpus/PowerPC,970@0/linux,boot-cpu property is an example of a +property without a value. All other properties have a value. The +significance of the #address-cells and #size-cells properties will be +explained in chapter IV which defines precisely the required nodes and +properties and their content. + + +3) Device tree "structure" block + +The structure of the device tree is a linearized tree structure. The +"OF_DT_BEGIN_NODE" token starts a new node, and the "OF_DT_END_NODE" +ends that node definition. Child nodes are simply defined before +"OF_DT_END_NODE" (that is nodes within the node). A 'token' is a 32 +bit value. The tree has to be "finished" with a OF_DT_END token + +Here's the basic structure of a single node: + + * token OF_DT_BEGIN_NODE (that is 0x00000001) + * for version 1 to 3, this is the node full path as a zero + terminated string, starting with "/". For version 16 and later, + this is the node unit name only (or an empty string for the + root node) + * [align gap to next 4 bytes boundary] + * for each property: + * token OF_DT_PROP (that is 0x00000003) + * 32 bit value of property value size in bytes (or 0 of no + * value) + * 32 bit value of offset in string block of property name + * property value data if any + * [align gap to next 4 bytes boundary] + * [child nodes if any] + * token OF_DT_END_NODE (that is 0x00000002) + +So the node content can be summmarised as a start token, a full path, +a list of properties, a list of child node and an end token. Every +child node is a full node structure itself as defined above. + +4) Device tree 'strings" block + +In order to save space, property names, which are generally redundant, +are stored separately in the "strings" block. This block is simply the +whole bunch of zero terminated strings for all property names +concatenated together. The device-tree property definitions in the +structure block will contain offset values from the beginning of the +strings block. + + +III - Required content of the device tree +========================================= + +WARNING: All "linux,*" properties defined in this document apply only +to a flattened device-tree. If your platform uses a real +implementation of Open Firmware or an implementation compatible with +the Open Firmware client interface, those properties will be created +by the trampoline code in the kernel's prom_init() file. For example, +that's where you'll have to add code to detect your board model and +set the platform number. However, when using the flatenned device-tree +entry point, there is no prom_init() pass, and thus you have to +provide those properties yourself. + + +1) Note about cells and address representation +---------------------------------------------- + +The general rule is documented in the various Open Firmware +documentations. If you chose to describe a bus with the device-tree +and there exist an OF bus binding, then you should follow the +specification. However, the kernel does not require every single +device or bus to be described by the device tree. + +In general, the format of an address for a device is defined by the +parent bus type, based on the #address-cells and #size-cells +property. In the absence of such a property, the parent's parent +values are used, etc... The kernel requires the root node to have +those properties defining addresses format for devices directly mapped +on the processor bus. + +Those 2 properties define 'cells' for representing an address and a +size. A "cell" is a 32 bit number. For example, if both contain 2 +like the example tree given above, then an address and a size are both +composed of 2 cells, and each is a 64 bit number (cells are +concatenated and expected to be in big endian format). Another example +is the way Apple firmware defines them, with 2 cells for an address +and one cell for a size. Most 32-bit implementations should define +#address-cells and #size-cells to 1, which represents a 32-bit value. +Some 32-bit processors allow for physical addresses greater than 32 +bits; these processors should define #address-cells as 2. + +"reg" properties are always a tuple of the type "address size" where +the number of cells of address and size is specified by the bus +#address-cells and #size-cells. When a bus supports various address +spaces and other flags relative to a given address allocation (like +prefetchable, etc...) those flags are usually added to the top level +bits of the physical address. For example, a PCI physical address is +made of 3 cells, the bottom two containing the actual address itself +while the top cell contains address space indication, flags, and pci +bus & device numbers. + +For busses that support dynamic allocation, it's the accepted practice +to then not provide the address in "reg" (keep it 0) though while +providing a flag indicating the address is dynamically allocated, and +then, to provide a separate "assigned-addresses" property that +contains the fully allocated addresses. See the PCI OF bindings for +details. + +In general, a simple bus with no address space bits and no dynamic +allocation is preferred if it reflects your hardware, as the existing +kernel address parsing functions will work out of the box. If you +define a bus type with a more complex address format, including things +like address space bits, you'll have to add a bus translator to the +prom_parse.c file of the recent kernels for your bus type. + +The "reg" property only defines addresses and sizes (if #size-cells +is +non-0) within a given bus. In order to translate addresses upward +(that is into parent bus addresses, and possibly into cpu physical +addresses), all busses must contain a "ranges" property. If the +"ranges" property is missing at a given level, it's assumed that +translation isn't possible. The format of the "ranges" proprety for a +bus is a list of: + + bus address, parent bus address, size + +"bus address" is in the format of the bus this bus node is defining, +that is, for a PCI bridge, it would be a PCI address. Thus, (bus +address, size) defines a range of addresses for child devices. "parent +bus address" is in the format of the parent bus of this bus. For +example, for a PCI host controller, that would be a CPU address. For a +PCI<->ISA bridge, that would be a PCI address. It defines the base +address in the parent bus where the beginning of that range is mapped. + +For a new 64 bit powerpc board, I recommend either the 2/2 format or +Apple's 2/1 format which is slightly more compact since sizes usually +fit in a single 32 bit word. New 32 bit powerpc boards should use a +1/1 format, unless the processor supports physical addresses greater +than 32-bits, in which case a 2/1 format is recommended. + + +2) Note about "compatible" properties +------------------------------------- + +These properties are optional, but recommended in devices and the root +node. The format of a "compatible" property is a list of concatenated +zero terminated strings. They allow a device to express its +compatibility with a family of similar devices, in some cases, +allowing a single driver to match against several devices regardless +of their actual names. + +3) Note about "name" properties +------------------------------- + +While earlier users of Open Firmware like OldWorld macintoshes tended +to use the actual device name for the "name" property, it's nowadays +considered a good practice to use a name that is closer to the device +class (often equal to device_type). For example, nowadays, ethernet +controllers are named "ethernet", an additional "model" property +defining precisely the chip type/model, and "compatible" property +defining the family in case a single driver can driver more than one +of these chips. However, the kernel doesn't generally put any +restriction on the "name" property; it is simply considered good +practice to follow the standard and its evolutions as closely as +possible. + +Note also that the new format version 16 makes the "name" property +optional. If it's absent for a node, then the node's unit name is then +used to reconstruct the name. That is, the part of the unit name +before the "@" sign is used (or the entire unit name if no "@" sign +is present). + +4) Note about node and property names and character set +------------------------------------------------------- + +While open firmware provides more flexibe usage of 8859-1, this +specification enforces more strict rules. Nodes and properties should +be comprised only of ASCII characters 'a' to 'z', '0' to +'9', ',', '.', '_', '+', '#', '?', and '-'. Node names additionally +allow uppercase characters 'A' to 'Z' (property names should be +lowercase. The fact that vendors like Apple don't respect this rule is +irrelevant here). Additionally, node and property names should always +begin with a character in the range 'a' to 'z' (or 'A' to 'Z' for node +names). + +The maximum number of characters for both nodes and property names +is 31. In the case of node names, this is only the leftmost part of +a unit name (the pure "name" property), it doesn't include the unit +address which can extend beyond that limit. + + +5) Required nodes and properties +-------------------------------- + These are all that are currently required. However, it is strongly + recommended that you expose PCI host bridges as documented in the + PCI binding to open firmware, and your interrupt tree as documented + in OF interrupt tree specification. + + a) The root node + + The root node requires some properties to be present: + + - model : this is your board name/model + - #address-cells : address representation for "root" devices + - #size-cells: the size representation for "root" devices + + Additionally, some recommended properties are: + + - compatible : the board "family" generally finds its way here, + for example, if you have 2 board models with a similar layout, + that typically get driven by the same platform code in the + kernel, you would use a different "model" property but put a + value in "compatible". The kernel doesn't directly use that + value (see /chosen/linux,platform for how the kernel choses a + platform type) but it is generally useful. + + The root node is also generally where you add additional properties + specific to your board like the serial number if any, that sort of + thing. it is recommended that if you add any "custom" property whose + name may clash with standard defined ones, you prefix them with your + vendor name and a comma. + + b) The /cpus node + + This node is the parent of all individual CPU nodes. It doesn't + have any specific requirements, though it's generally good practice + to have at least: + + #address-cells = <00000001> + #size-cells = <00000000> + + This defines that the "address" for a CPU is a single cell, and has + no meaningful size. This is not necessary but the kernel will assume + that format when reading the "reg" properties of a CPU node, see + below + + c) The /cpus/* nodes + + So under /cpus, you are supposed to create a node for every CPU on + the machine. There is no specific restriction on the name of the + CPU, though It's common practice to call it PowerPC,. For + example, Apple uses PowerPC,G5 while IBM uses PowerPC,970FX. + + Required properties: + + - device_type : has to be "cpu" + - reg : This is the physical cpu number, it's a single 32 bit cell + and is also used as-is as the unit number for constructing the + unit name in the full path. For example, with 2 CPUs, you would + have the full path: + /cpus/PowerPC,970FX@0 + /cpus/PowerPC,970FX@1 + (unit addresses do not require leading zeroes) + - d-cache-line-size : one cell, L1 data cache line size in bytes + - i-cache-line-size : one cell, L1 instruction cache line size in + bytes + - d-cache-size : one cell, size of L1 data cache in bytes + - i-cache-size : one cell, size of L1 instruction cache in bytes + - linux, boot-cpu : Should be defined if this cpu is the boot cpu. + + Recommended properties: + + - timebase-frequency : a cell indicating the frequency of the + timebase in Hz. This is not directly used by the generic code, + but you are welcome to copy/paste the pSeries code for setting + the kernel timebase/decrementer calibration based on this + value. + - clock-frequency : a cell indicating the CPU core clock frequency + in Hz. A new property will be defined for 64 bit values, but if + your frequency is < 4Ghz, one cell is enough. Here as well as + for the above, the common code doesn't use that property, but + you are welcome to re-use the pSeries or Maple one. A future + kernel version might provide a common function for this. + + You are welcome to add any property you find relevant to your board, + like some information about the mechanism used to soft-reset the + CPUs. For example, Apple puts the GPIO number for CPU soft reset + lines in there as a "soft-reset" property since they start secondary + CPUs by soft-resetting them. + + + d) the /memory node(s) + + To define the physical memory layout of your board, you should + create one or more memory node(s). You can either create a single + node with all memory ranges in its reg property, or you can create + several nodes, as you wish. The unit address (@ part) used for the + full path is the address of the first range of memory defined by a + given node. If you use a single memory node, this will typically be + @0. + + Required properties: + + - device_type : has to be "memory" + - reg : This property contains all the physical memory ranges of + your board. It's a list of addresses/sizes concatenated + together, with the number of cells of each defined by the + #address-cells and #size-cells of the root node. For example, + with both of these properties beeing 2 like in the example given + earlier, a 970 based machine with 6Gb of RAM could typically + have a "reg" property here that looks like: + + 00000000 00000000 00000000 80000000 + 00000001 00000000 00000001 00000000 + + That is a range starting at 0 of 0x80000000 bytes and a range + starting at 0x100000000 and of 0x100000000 bytes. You can see + that there is no memory covering the IO hole between 2Gb and + 4Gb. Some vendors prefer splitting those ranges into smaller + segments, but the kernel doesn't care. + + e) The /chosen node + + This node is a bit "special". Normally, that's where open firmware + puts some variable environment information, like the arguments, or + phandle pointers to nodes like the main interrupt controller, or the + default input/output devices. + + This specification makes a few of these mandatory, but also defines + some linux-specific properties that would be normally constructed by + the prom_init() trampoline when booting with an OF client interface, + but that you have to provide yourself when using the flattened format. + + Required properties: + + - linux,platform : This is your platform number as assigned by the + architecture maintainers + + Recommended properties: + + - bootargs : This zero-terminated string is passed as the kernel + command line + - linux,stdout-path : This is the full path to your standard + console device if any. Typically, if you have serial devices on + your board, you may want to put the full path to the one set as + the default console in the firmware here, for the kernel to pick + it up as it's own default console. If you look at the funciton + set_preferred_console() in arch/ppc64/kernel/setup.c, you'll see + that the kernel tries to find out the default console and has + knowledge of various types like 8250 serial ports. You may want + to extend this function to add your own. + - interrupt-controller : This is one cell containing a phandle + value that matches the "linux,phandle" property of your main + interrupt controller node. May be used for interrupt routing. + + + Note that u-boot creates and fills in the chosen node for platforms + that use it. + + f) the /soc node + + This node is used to represent a system-on-a-chip (SOC) and must be + present if the processor is a SOC. The top-level soc node contains + information that is global to all devices on the SOC. The node name + should contain a unit address for the SOC, which is the base address + of the memory-mapped register set for the SOC. The name of an soc + node should start with "soc", and the remainder of the name should + represent the part number for the soc. For example, the MPC8540's + soc node would be called "soc8540". + + Required properties: + + - device_type : Should be "soc" + - ranges : Should be defined as specified in 1) to describe the + translation of SOC addresses for memory mapped SOC registers. + + Recommended properties: + + - reg : This property defines the address and size of the + memory-mapped registers that are used for the SOC node itself. + It does not include the child device registers - these will be + defined inside each child node. The address specified in the + "reg" property should match the unit address of the SOC node. + - #address-cells : Address representation for "soc" devices. The + format of this field may vary depending on whether or not the + device registers are memory mapped. For memory mapped + registers, this field represents the number of cells needed to + represent the address of the registers. For SOCs that do not + use MMIO, a special address format should be defined that + contains enough cells to represent the required information. + See 1) above for more details on defining #address-cells. + - #size-cells : Size representation for "soc" devices + - #interrupt-cells : Defines the width of cells used to represent + interrupts. Typically this value is <2>, which includes a + 32-bit number that represents the interrupt number, and a + 32-bit number that represents the interrupt sense and level. + This field is only needed if the SOC contains an interrupt + controller. + + The SOC node may contain child nodes for each SOC device that the + platform uses. Nodes should not be created for devices which exist + on the SOC but are not used by a particular platform. See chapter VI + for more information on how to specify devices that are part of an +SOC. + + Example SOC node for the MPC8540: + + soc8540@e0000000 { + #address-cells = <1>; + #size-cells = <1>; + #interrupt-cells = <2>; + device_type = "soc"; + ranges = <00000000 e0000000 00100000> + reg = ; + } + + + +IV - "dtc", the device tree compiler +==================================== + + +dtc source code can be found at + + +WARNING: This version is still in early development stage; the +resulting device-tree "blobs" have not yet been validated with the +kernel. The current generated bloc lacks a useful reserve map (it will +be fixed to generate an empty one, it's up to the bootloader to fill +it up) among others. The error handling needs work, bugs are lurking, +etc... + +dtc basically takes a device-tree in a given format and outputs a +device-tree in another format. The currently supported formats are: + + Input formats: + ------------- + + - "dtb": "blob" format, that is a flattened device-tree block + with + header all in a binary blob. + - "dts": "source" format. This is a text file containing a + "source" for a device-tree. The format is defined later in this + chapter. + - "fs" format. This is a representation equivalent to the + output of /proc/device-tree, that is nodes are directories and + properties are files + + Output formats: + --------------- + + - "dtb": "blob" format + - "dts": "source" format + - "asm": assembly language file. This is a file that can be + sourced by gas to generate a device-tree "blob". That file can + then simply be added to your Makefile. Additionally, the + assembly file exports some symbols that can be use + + +The syntax of the dtc tool is + + dtc [-I ] [-O ] + [-o output-filename] [-V output_version] input_filename + + +The "output_version" defines what versio of the "blob" format will be +generated. Supported versions are 1,2,3 and 16. The default is +currently version 3 but that may change in the future to version 16. + +Additionally, dtc performs various sanity checks on the tree, like the +uniqueness of linux,phandle properties, validity of strings, etc... + +The format of the .dts "source" file is "C" like, supports C and C++ +style commments. + +/ { +} + +The above is the "device-tree" definition. It's the only statement +supported currently at the toplevel. + +/ { + property1 = "string_value"; /* define a property containing a 0 + * terminated string + */ + + property2 = <1234abcd>; /* define a property containing a + * numerical 32 bits value (hexadecimal) + */ + + property3 = <12345678 12345678 deadbeef>; + /* define a property containing 3 + * numerical 32 bits values (cells) in + * hexadecimal + */ + property4 = [0a 0b 0c 0d de ea ad be ef]; + /* define a property whose content is + * an arbitrary array of bytes + */ + + childnode@addresss { /* define a child node named "childnode" + * whose unit name is "childnode at + * address" + */ + + childprop = "hello\n"; /* define a property "childprop" of + * childnode (in this case, a string) + */ + }; +}; + +Nodes can contain other nodes etc... thus defining the hierarchical +structure of the tree. + +Strings support common escape sequences from C: "\n", "\t", "\r", +"\(octal value)", "\x(hex value)". + +It is also suggested that you pipe your source file through cpp (gcc +preprocessor) so you can use #include's, #define for constants, etc... + +Finally, various options are planned but not yet implemented, like +automatic generation of phandles, labels (exported to the asm file so +you can point to a property content and change it easily from whatever +you link the device-tree with), label or path instead of numeric value +in some cells to "point" to a node (replaced by a phandle at compile +time), export of reserve map address to the asm file, ability to +specify reserve map content at compile time, etc... + +We may provide a .h include file with common definitions of that +proves useful for some properties (like building PCI properties or +interrupt maps) though it may be better to add a notion of struct +definitions to the compiler... + + +V - Recommendations for a bootloader +==================================== + + +Here are some various ideas/recommendations that have been proposed +while all this has been defined and implemented. + + - The bootloader may want to be able to use the device-tree itself + and may want to manipulate it (to add/edit some properties, + like physical memory size or kernel arguments). At this point, 2 + choices can be made. Either the bootloader works directly on the + flattened format, or the bootloader has its own internal tree + representation with pointers (similar to the kernel one) and + re-flattens the tree when booting the kernel. The former is a bit + more difficult to edit/modify, the later requires probably a bit + more code to handle the tree structure. Note that the structure + format has been designed so it's relatively easy to "insert" + properties or nodes or delete them by just memmoving things + around. It contains no internal offsets or pointers for this + purpose. + + - An example of code for iterating nodes & retreiving properties + directly from the flattened tree format can be found in the kernel + file arch/ppc64/kernel/prom.c, look at scan_flat_dt() function, + it's usage in early_init_devtree(), and the corresponding various + early_init_dt_scan_*() callbacks. That code can be re-used in a + GPL bootloader, and as the author of that code, I would be happy + do discuss possible free licencing to any vendor who wishes to + integrate all or part of this code into a non-GPL bootloader. + + + +VI - System-on-a-chip devices and nodes +======================================= + +Many companies are now starting to develop system-on-a-chip +processors, where the processor core (cpu) and many peripheral devices +exist on a single piece of silicon. For these SOCs, an SOC node +should be used that defines child nodes for the devices that make +up the SOC. While platforms are not required to use this model in +order to boot the kernel, it is highly encouraged that all SOC +implementations define as complete a flat-device-tree as possible to +describe the devices on the SOC. This will allow for the +genericization of much of the kernel code. + + +1) Defining child nodes of an SOC +--------------------------------- + +Each device that is part of an SOC may have its own node entry inside +the SOC node. For each device that is included in the SOC, the unit +address property represents the address offset for this device's +memory-mapped registers in the parent's address space. The parent's +address space is defined by the "ranges" property in the top-level soc +node. The "reg" property for each node that exists directly under the +SOC node should contain the address mapping from the child address space +to the parent SOC address space and the size of the device's +memory-mapped register file. + +For many devices that may exist inside an SOC, there are predefined +specifications for the format of the device tree node. All SOC child +nodes should follow these specifications, except where noted in this +document. + +See appendix A for an example partial SOC node definition for the +MPC8540. + + +2) Specifying interrupt information for SOC devices +--------------------------------------------------- + +Each device that is part of an SOC and which generates interrupts +should have the following properties: + + - interrupt-parent : contains the phandle of the interrupt + controller which handles interrupts for this device + - interrupts : a list of tuples representing the interrupt + number and the interrupt sense and level for each interupt + for this device. + +This information is used by the kernel to build the interrupt table +for the interrupt controllers in the system. + +Sense and level information should be encoded as follows: + + Devices connected to openPIC-compatible controllers should encode + sense and polarity as follows: + + 0 = high to low edge sensitive type enabled + 1 = active low level sensitive type enabled + 2 = low to high edge sensitive type enabled + 3 = active high level sensitive type enabled + + ISA PIC interrupt controllers should adhere to the ISA PIC + encodings listed below: + + 0 = active low level sensitive type enabled + 1 = active high level sensitive type enabled + 2 = high to low edge sensitive type enabled + 3 = low to high edge sensitive type enabled + + + +3) Representing devices without a current OF specification +---------------------------------------------------------- + +Currently, there are many devices on SOCs that do not have a standard +representation pre-defined as part of the open firmware +specifications, mainly because the boards that contain these SOCs are +not currently booted using open firmware. This section contains +descriptions for the SOC devices for which new nodes have been +defined; this list will expand as more and more SOC-containing +platforms are moved over to use the flattened-device-tree model. + + a) MDIO IO device + + The MDIO is a bus to which the PHY devices are connected. For each + device that exists on this bus, a child node should be created. See + the definition of the PHY node below for an example of how to define + a PHY. + + Required properties: + - reg : Offset and length of the register set for the device + - device_type : Should be "mdio" + - compatible : Should define the compatible device type for the + mdio. Currently, this is most likely to be "gianfar" + + Example: + + mdio@24520 { + reg = <24520 20>; + + ethernet-phy@0 { + ...... + }; + }; + + + b) Gianfar-compatible ethernet nodes + + Required properties: + + - device_type : Should be "network" + - model : Model of the device. Can be "TSEC", "eTSEC", or "FEC" + - compatible : Should be "gianfar" + - reg : Offset and length of the register set for the device + - address : List of bytes representing the ethernet address of + this controller + - interrupts : where a is the interrupt number and b is a + field that represents an encoding of the sense and level + information for the interrupt. This should be encoded based on + the information in section 2) depending on the type of interrupt + controller you have. + - interrupt-parent : the phandle for the interrupt controller that + services interrupts for this device. + - phy-handle : The phandle for the PHY connected to this ethernet + controller. + + Example: + + ethernet@24000 { + #size-cells = <0>; + device_type = "network"; + model = "TSEC"; + compatible = "gianfar"; + reg = <24000 1000>; + address = [ 00 E0 0C 00 73 00 ]; + interrupts = ; + interrupt-parent = <40000>; + phy-handle = <2452000> + }; + + + + c) PHY nodes + + Required properties: + + - device_type : Should be "ethernet-phy" + - interrupts : where a is the interrupt number and b is a + field that represents an encoding of the sense and level + information for the interrupt. This should be encoded based on + the information in section 2) depending on the type of interrupt + controller you have. + - interrupt-parent : the phandle for the interrupt controller that + services interrupts for this device. + - reg : The ID number for the phy, usually a small integer + - linux,phandle : phandle for this node; likely referenced by an + ethernet controller node. + + + Example: + + ethernet-phy@0 { + linux,phandle = <2452000> + interrupt-parent = <40000>; + interrupts = <35 1>; + reg = <0>; + device_type = "ethernet-phy"; + }; + + + d) Interrupt controllers + + Some SOC devices contain interrupt controllers that are different + from the standard Open PIC specification. The SOC device nodes for + these types of controllers should be specified just like a standard + OpenPIC controller. Sense and level information should be encoded + as specified in section 2) of this chapter for each device that + specifies an interrupt. + + Example : + + pic@40000 { + linux,phandle = <40000>; + clock-frequency = <0>; + interrupt-controller; + #address-cells = <0>; + reg = <40000 40000>; + built-in; + compatible = "chrp,open-pic"; + device_type = "open-pic"; + big-endian; + }; + + + e) I2C + + Required properties : + + - device_type : Should be "i2c" + - reg : Offset and length of the register set for the device + + Recommended properties : + + - compatible : Should be "fsl-i2c" for parts compatible with + Freescale I2C specifications. + - interrupts : where a is the interrupt number and b is a + field that represents an encoding of the sense and level + information for the interrupt. This should be encoded based on + the information in section 2) depending on the type of interrupt + controller you have. + - interrupt-parent : the phandle for the interrupt controller that + services interrupts for this device. + - dfsrr : boolean; if defined, indicates that this I2C device has + a digital filter sampling rate register + - fsl5200-clocking : boolean; if defined, indicated that this device + uses the FSL 5200 clocking mechanism. + + Example : + + i2c@3000 { + interrupt-parent = <40000>; + interrupts = <1b 3>; + reg = <3000 18>; + device_type = "i2c"; + compatible = "fsl-i2c"; + dfsrr; + }; + + + More devices will be defined as this spec matures. + + +Appendix A - Sample SOC node for MPC8540 +======================================== + +Note that the #address-cells and #size-cells for the SoC node +in this example have been explicitly listed; these are likely +not necessary as they are usually the same as the root node. + + soc8540@e0000000 { + #address-cells = <1>; + #size-cells = <1>; + #interrupt-cells = <2>; + device_type = "soc"; + ranges = <00000000 e0000000 00100000> + reg = ; + + mdio@24520 { + reg = <24520 20>; + device_type = "mdio"; + compatible = "gianfar"; + + ethernet-phy@0 { + linux,phandle = <2452000> + interrupt-parent = <40000>; + interrupts = <35 1>; + reg = <0>; + device_type = "ethernet-phy"; + }; + + ethernet-phy@1 { + linux,phandle = <2452001> + interrupt-parent = <40000>; + interrupts = <35 1>; + reg = <1>; + device_type = "ethernet-phy"; + }; + + ethernet-phy@3 { + linux,phandle = <2452002> + interrupt-parent = <40000>; + interrupts = <35 1>; + reg = <3>; + device_type = "ethernet-phy"; + }; + + }; + + ethernet@24000 { + #size-cells = <0>; + device_type = "network"; + model = "TSEC"; + compatible = "gianfar"; + reg = <24000 1000>; + address = [ 00 E0 0C 00 73 00 ]; + interrupts = ; + interrupt-parent = <40000>; + phy-handle = <2452000>; + }; + + ethernet@25000 { + #address-cells = <1>; + #size-cells = <0>; + device_type = "network"; + model = "TSEC"; + compatible = "gianfar"; + reg = <25000 1000>; + address = [ 00 E0 0C 00 73 01 ]; + interrupts = <13 3 14 3 18 3>; + interrupt-parent = <40000>; + phy-handle = <2452001>; + }; + + ethernet@26000 { + #address-cells = <1>; + #size-cells = <0>; + device_type = "network"; + model = "FEC"; + compatible = "gianfar"; + reg = <26000 1000>; + address = [ 00 E0 0C 00 73 02 ]; + interrupts = <19 3>; + interrupt-parent = <40000>; + phy-handle = <2452002>; + }; + + serial@4500 { + device_type = "serial"; + compatible = "ns16550"; + reg = <4500 100>; + clock-frequency = <0>; + interrupts = <1a 3>; + interrupt-parent = <40000>; + }; + + pic@40000 { + linux,phandle = <40000>; + clock-frequency = <0>; + interrupt-controller; + #address-cells = <0>; + reg = <40000 40000>; + built-in; + compatible = "chrp,open-pic"; + device_type = "open-pic"; + big-endian; + }; + + i2c@3000 { + interrupt-parent = <40000>; + interrupts = <1b 3>; + reg = <3000 18>; + device_type = "i2c"; + compatible = "fsl-i2c"; + dfsrr; + }; + + }; -- GitLab From 537421be79b94bcf620467f50dd9e38b739c2a00 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Wed, 1 Feb 2006 03:05:24 -0800 Subject: [PATCH 0460/1843] [PATCH] Mark CONFIG_UFS_FS_WRITE as BROKEN OpenBSD doesn't see "." correctly in directories created by Linux.

Currently the zone_reclaim code has a fixed window of 30 seconds of off node allocations should a local zone have no unused pagecache pages left. Reclaim will be attempted again after this timeout period to avoid repeated useless scans for memory. This is also useful to established sufficiently large off node allocation chunks to relieve the local node. It may be beneficial to adjust that time period for some special situations. For example if memory use was exceeding node capacity one may want to give up for longer periods of time. If memory spikes intermittendly then one may want to shorten the time period to reduce the number of off node allocations. This patch allows just that....

For example a process writing large amounts of memory will spew unto other nodes to cache the writes if many pages in a zone become dirty. This may impact the performance of processes running on other nodes. Allowing writes during reclaim puts a stop to that behavior and throttles the process by restricting the pages to the local zone.

This patch shakes the slab a bit. The problem with this patch is that the slab reclaim is not containable to a zone. Thus slab reclaim may affect the whole system and be extremely slow. This also means that we cannot determine how many pages were freed in this zone. Thus we need to go off node for at least one allocation. The functionality is disabled by default. We could modify the shrinkers to take a zone parameter but that would be quite invasive. Better ideas are welcome.

The page migration code may change a swap pte to point to a different page under lock_page(). If that happens then the vm must retry the lookup operation in the swap space to find the correct page number. There are a couple of locations in the VM where a lock_page() is done on a swap page. In these locations we need to check afterwards if the page was migrated. If the page was migrated then the old page that was looked up before was freed and no longer has the PageSwapCache bit set.

Prep the new page that we want to move to. It is locked + and set to not being uptodate so that all accesses to the new + page immediately lock while we are moving references. + +5. All the page table references to the page are either dropped (file backed) + or converted to swap references (anonymous pages). This should decrease the + reference count. + +6.

If the mapping is gone then a truncate action may + be in progress and we back out. + +10. The new page is prepped with some settings from the old page so that accesses + to the new page will be discovered to have the correct settings. + +11.

The swapper address space operation are modified so that a regular migrate_page() will occur for anonymous pages without writeback (migrate_pages forces every anonymous page to have a swap entry).

We first calculate the maximum number of objects a slab can hold after struct slab and kmem_bufctl_t for each object has been given enough space. After that, to respect alignment rules, we decrease the number of objects if necessary. As required padding is at most align-1 and memory of obj_size is at least align, it is always enough to decrease number of objects by one. The optimization was originally made by Balbir Singh with more improvements from Steven Rostedt.

The patch also removes the sysfs attributes from windfarm_pm81 and windfarm_pm91 and instead adds code to the windfarm core to automagically expose attributes for sensor & controls.

If the operation cannot complete atomically, it is aborted from the usr_entry macro by clearing the Z flag. This clearing of the Z flag is done whenever the user pc is above TASK_SIZE. However this "pc >= TASK_SIZE" test cannot work in the non MMU case. Worse: the current code will corrupt the Z flag on every entry to the kernel. Let's disable it in the non MMU case for now. Using NPTL on non MMU targets needs to be worked out anyway.

Destination socket is used in the place where it was meant to be source socket, so that now overrun is never sent to user netlink sockets, when it should be, and it even can be set on kernel socket, which results in complete deadlock of rtnetlink. Suggested fix is to restore status quo passing source socket as additional argument to netlink_attachskb(). A little explanation: overrun is set on a socket, when it failed to receive some message and sender of this messages does not or even have no way to handle this error. This happens in two cases: 1. when kernel sends something. Kernel never retransmits and cannot wait for buffer space. 2. when user sends a broadcast and the message was not delivered to some recipients. Signed-off-by: Alexey Kuznetsov Signed-off-by: David S.

Basically I have had similar observations to Suresh in that it does not play nicely with the rest of the balancing infrastructure (and raised similar concerns in my review). The samples (group of 4) I got for "maximum recorded imbalance" on a 2x2 SMP+HT Xeon are as follows: | Following boot | hackbench 20 | hackbench 40 -----------+----------------+---------------------+--------------------- 2.6.16-rc2 | 30,37,100,112 | 5600,5530,6020,6090 | 6390,7090,8760,8470 +nosmpnice | 3, 2, 4, 2 | 28, 150, 294, 132 | 348, 348, 294, 347 Hackbench raw performance is down around 15% with smpnice (but that in itself isn't a huge deal because it is just a benchmark). However, the samples show that the imbalance passed into move_tasks is increased by about a factor of 10-30. I think this would also go some way to explaining latency blips turning up in the balancing code (though I haven't actually measured that). We'll probably have to revert this in the SUSE kernel.

When the initrd region is freed, the second kernel memory will not be contiguous. The Kexec_load can cause an oops since there is no contiguous memory to write the second kernel or this memory could be used in the first kernel itself and may not be part of the dump. For example, on powerpc, the initrd is located at 36MB and the crashkernel starts at 32MB. The kexec_load caused panic since writing into non-allocated memory (after 36MB). We could see the similar issue even on other archs. One possibility is to move the initrd outside of crashkernel region. But, the initrd region will be freed anyway before the system is up. This patch fixes this issue and frees only regions that are not part of crashkernel memory in case overlaps. Signed-off-by: Haren Myneni Acked-by: "Eric W.

The result is that on 32-bit platforms we don't have all the information needed to implement fstatat64. This patch modifies the code to pass up 64-bit information if __ARCH_WANT_STAT64 is defined. I renamed the syscall entry point to make this clear. Other archs will continue to use the existing code. On x86-64 the compat code is implemented using a new sys32_ function. this is what is done for the other stat syscalls as well. This patch might break some other archs (those which define __ARCH_WANT_STAT64 and which already wired up the syscall). Yet others might need changes to accomodate the compatibility mode. I really don't want to do that work because all this stat handling is a mess (more so in glibc, but the kernel is also affected). It should be done by the arch maintainers. I'll provide some stand-alone test shortly. Those who are eager could compile glibc and run 'make check' (no installation needed). The patch below has been tested on x86 and x86-64.

Since the current Linux code relies on it use a mixed mode with both PIT for the interrupt and HPET counters for the time keeping. That was already implemented, but didn't work properly because it was still using the last interrupt offset in HPET. This resulted in x460 not booting. Fix this up by using the free running HPET counter. Shouldn't affect any other machine because they either use full HPET mode or no HPET at all. TBD needs a similar 32bit fix.

We were writing back a timeout larger than the original. We _deliberately_ round up, since we know we must wait at _least_ as long as the caller asks us to. The patch adds a couple of helper functions for magnitude comparison of timespecs and of timevals, and uses them to prevent the various poll and select functions from returning a timeout which is larger than the one which was passed in. The patch also fixes a bug in compat_sys_pselect7(): it was adding the new timeout value to the old one and was returning that. It should just return the new timeout value. (We have various handy timespec/timeval-to-from-nsec conversion functions in time.h. But this code open-codes it all). Cc: "David S.

The problem seems that a task can get preempted out of the do_debug() processing while it is running on the DEBUG_STACK stack. If another task on that same cpu then enters do_debug() and uses the same per-cpu DEBUG_STACK stack, the previous preempted tasks's stack contents can be corrupted, and the system will oops when the preempted task is context switched back in again.

Problem discovered and initial patch by Olaf Kirch: there's a problem with IPsec that has been bugging some of our users for the last couple of kernel revs. Every now and then, IPsec will freeze the machine completely. This is with openswan user land, and with kernels up to and including 2.6.16-rc2. I managed to debug this a little, and what happens is that we end up looping in xfrm_lookup, and never get out. With a bit of debug printks added, I can this happening: ip_route_output_flow calls xfrm_lookup xfrm_find_bundle returns NULL (apparently we're in the middle of negotiating a new SA or something) We therefore call xfrm_tmpl_resolve. This returns EAGAIN We go to sleep, waiting for a policy update. Then we loop back to the top Apparently, the dst_orig that was passed into xfrm_lookup has been dropped from the routing table (obsolete=2) This leads to the endless loop, because we now create a new bundle, check the new bundle and find it's stale (stale_bundle -> xfrm_bundle_ok -> dst_check() return 0) People have been testing with the patch below, which seems to fix the problem partially. They still see connection hangs however (things only clear up when they start a new ping or new ssh). So the patch is obvsiouly not sufficient, and something else seems to go wrong. I'm grateful for any hints you may have... I suggest that we simply bail out always. If the dst decides to die on us later on, the packet will be dropped anyway. So there is no great urgency to retry here. Once we have the proper resolution queueing, we can then do the retry again. Signed-off-by: Herbert Xu Acked-by: Olaf Kirch Signed-off-by: David S.

This API gets around the issue by executing the function directly if the caller has process context, but scheduling a workqueue to execute in process context if the caller doesn't have it. Unfortunately, it requires memory allocation in interrupt context, but it's better than what we have previously.

If CONFIG_KALLSYMS was disabled, get_wchan() just returns thread_saved_pc() value. Also unwind stackframe based on "addiu sp,-imm" analysis instead of frame pointer.

From Richard Sandiford : This patch caused a miscompilation of the restore_gp_regs() block in restore_sigcontext(). This was in a 32-bit kernel compiled with GCC CVS head. restore_gp_regs() copies 64-bit user fields into 32-bit variables, and in this combination, the new __get_user_asm_ll32() clobbers too many registers. It says: /* * Get a long long 64 using 32 bit registers. */ { \ __asm__ __volatile__( \ "1: lw %1, (%3) \n" \ "2: lw %D1, 4(%3) \n" \ " move %0, $0 \n" \ "3: .section .fixup,\"ax\" \n" \ "4: li %0, %4 \n" \ " move %1, $0 \n" \ " move %D1, $0 \n" \ " j 3b \n" \ " .previous \n" \ " .section __ex_table,\"a\" \n" \ " " __UA_ADDR " 1b, 4b \n" \ " " __UA_ADDR " 2b, 4b \n" \ " .previous \n" \ : "=r" (__gu_err), "=&r" (val) \ : "0" (0), "r" (addr), "i" (-EFAULT)); \ } and this requires val (%1) to be a 64-bit value. In the case I saw, gcc was using $3 for the 32-bit val, and wasn't expecting $4 to be clobbered.

But that's rather a poor place to keep it: functions which call set_page_dirty_lock after get_user_pages (e.g. Infiniband's __ib_umem_release) ought to be checking first, otherwise set_page_dirty is liable to crash on what's not the address of a struct address_space. And now I'm about to make that worse: it turns out that every compound page needs a destructor, so we can no longer rely on hugetlb pages going their own special way, to avoid further problems of page->mapping reuse. For example, not many people know that: on 50% of i386 -Os builds, the first tail page of a compound page purports to be PageAnon (when its destructor has an odd address), which surprises page_add_file_rmap. Keep the compound page destructor in page[1].lru.next instead. And to free up the common pairing of mapping and index, also move compound page order from index to lru.prev. Slab reuses page->lru too: but if we ever need slab to use compound pages, it can easily stack its use above this. (akpm: decoded version of the above: the tail pages of a compound page now have ->mapping==NULL, so there's no need for the set_page_dirty[_lock]() caller to check that they're not compund pages before doing the dirty).

No, we must supply a default destructor, __free_pages_ok using the order noted by prep_compound_page. hugetlb can still replace this as before with its own free_huge_page pointer. The case that needs this is not common: rarely does put_compound_page's put_page_testzero bring the count down to 0. But if get_user_pages is applied to some part of a compound page, without immediate release (e.g. AIO or Infiniband), then it's possible for its put_page to come after the containing vma has been unmapped and the driver done its free_pages. That's just the kind of case compound pages are supposed to be guarding against (but Nick points out, nor did PageReserved handle this right).

Currently when the NLM_GRANTED callback comes in, lockd walks the list of blocked locks in search of a match to the lock that the NLM server has granted. Although it checks the lock pid, start and end, it fails to check the filehandle and the server address. By checking the filehandle and server IP address, we ensure that this only happens if the locks truly are referencing the same file.

This happens if the process forks meanwhile, and the parent writes to that page. As a result, the page is orphaned: in case of get_user_pages, the application will never see any data hardware DMA's into this page after the COW. In case of mlock'd memory, the parent is not getting the realtime/security benefits of mlock. In particular, this affects the Infiniband modules which do DMA from and into user pages all the time. This patch adds madvise options to control whether memory range is inherited across fork. Useful e.g. for when hardware is doing DMA from/into these pages. Could also be useful to an application wanting to speed up its forks by cutting large areas out of consideration. Signed-off-by: Michael S.

Feb 2006 13:53:10 -0800 Subject: [PATCH 1252/1843] [PATCH] sched: revert "filter affine wakeups" Revert commit d7102e95b7b9c00277562c29aad421d2d521c5f6: [PATCH] sched: filter affine wakeups Apparently caused more than 10% performance regression for aim7 benchmark. The setup in use is 16-cpu HP rx8620, 64Gb of memory and 12 MSA1000s with 144 disks. Each disk is 72Gb with a single ext3 filesystem (courtesy of HP, who supplied benchmark results). The problem is, for aim7, the wake-up pattern is random, but it still needs load balancing action in the wake-up path to achieve best performance. With the above commit, lack of load balancing hurts that workload. However, for workloads like database transaction processing, the requirement is exactly opposite. In the wake up path, best performance is achieved with absolutely zero load balancing. We simply wake up the process on the CPU that it was previously run. Worst performance is obtained when we do load balancing at wake up. There isn't an easy way to auto detect the workload characteristics. Ingo's earlier patch that detects idle CPU and decide whether to load balance or not doesn't perform with aim7 either since all CPUs are busy (it causes even bigger perf. regression). Revert commit d7102e95b7b9c00277562c29aad421d2d521c5f6, which causes more than 10% performance regression with aim7.

The way this is done is to dedicate one of the four integer condition code registers (ICC2) to maintaining a virtual interrupt disablement state whilst inside the kernel. This uses the ICC2.Z flag (Zero) to indicate whether the interrupts are virtually disabled and the ICC2.C flag (Carry) to indicate whether the interrupts are physically disabled. ICC2.Z is set to indicate interrupts are virtually disabled. ICC2.C is set to indicate interrupts are physically enabled. Under normal running conditions Z==0 and C==1. Disabling interrupts with local_irq_disable() doesn't then actually physically disable interrupts - it merely sets ICC2.Z to 1. Should an interrupt then happen, the exception prologue will note ICC2.Z is set and branch out of line using one instruction (an unlikely BEQ). Here it will physically disable interrupts and clear ICC2.C. When it comes time to enable interrupts (local_irq_enable()), this simply clears the ICC2.Z flag and invokes a trap #2 if both Z and C flags are clear (the HI integer condition). This can be done with the TIHI conditional trap instruction. The trap then physically reenables interrupts and sets ICC2.C again. Upon returning the interrupt will be taken as interrupts will then be enabled. Note that whilst processing the trap, the whole exceptions system is disabled, and so an interrupt can't happen till it returns. If no pending interrupt had happened, ICC2.C would still be set, the HI condition would not be fulfilled, and no trap will happen. Saving interrupts (local_irq_save) is simply a matter of pulling the ICC2.Z flag out of the CCR register, shifting it down and masking it off. This gives a result of 0 if interrupts were enabled and 1 if they weren't. Restoring interrupts (local_irq_restore) is then a matter of taking the saved value mentioned previously and XOR'ing it against 1. If it was one, the result will be zero, and if it was zero the result will be non-zero. This result is then used to affect the ICC2.Z flag directly (it is a condition code flag after all). An XOR instruction does not affect the Carry flag, and so that bit of state is unchanged. The two flags can then be sampled to see if they're both zero using the trap (TIHI) as for the unconditional reenablement (local_irq_enable). This patch also: (1) Modifies the debugging stub (break.S) to handle single-stepping crossing into the trap #2 handler and into virtually disabled interrupts. (2) Removes superseded fixup pointers from the second instructions in the trap tables (there's no a separate fixup table for this). (3) Declares the trap #3 vector for use in .org directives in the trap table. (4) Moves irq_enter() and irq_exit() in do_IRQ() to avoid problems with virtual interrupt handling, and removes the duplicate code that has now been folded into irq_exit() (softirq and preemption handling). (5) Tells the compiler in the arch Makefile that ICC2 is now reserved. (6) Documents the in-kernel ABI, including the virtual interrupts. (7) Renames the old irq management functions to different names.

A number of the registers +are used for special purposed, and the ABI is not consistent between modules vs core, and MMU vs +no-MMU. + +This partly stems from the fact that FRV CPUs do not have a separate supervisor stack pointer, and +most of them do not have any scratch registers, thus requiring at least one general purpose +register to be clobbered in such an event. Also, within the kernel core, it is possible to simply +jump or call directly between functions using a relative offset. This cannot be extended to modules +for the displacement is likely to be too far.

In order of increasing capability: + + (1) User mode. + + Basic userspace running mode. + + (2) Kernel mode. + + Normal kernel mode. There are many additional control registers available that may be + accessed in this mode, in addition to all the stuff available to user mode. This has two + submodes: + + (a) Exceptions enabled (PSR.T == 1). + + Exceptions will invoke the appropriate normal kernel mode handler. On entry to the + handler, the PSR.T bit will be cleared. + + (b) Exceptions disabled (PSR.T == 0). + + No exceptions or interrupts may happen.

Hence +the debug mode code (gdbstub) is almost completely self-contained. The only external code used is +the sprintf family of functions. + +Futhermore, break.S is so complicated because single-step mode does not switch off on entry to an +exception. That means unless manually disabled, single-stepping will blithely go on stepping into +things like interrupts. See gdbstub.txt for more information. + + +========================== +VIRTUAL INTERRUPT HANDLING +========================== + +Because accesses to the PSR is so slow, and to disable interrupts we have to access it twice (once +to read and once to write), we don't actually disable interrupts at all if we don't have to. What +we do instead is use the ICC2 condition code flags to note virtual disablement, such that if we +then do take an interrupt, we note the flag, really disable interrupts, set another flag and resume +execution at the point the interrupt happened. Setting condition flags as a side effect of an +arithmetic or logical instruction is really fast. This use of the ICC2 only occurs within the +kernel - it does not affect userspace. + +The flags we use are: + + (*) CCR.ICC2.Z [Zero flag] + + Set to virtually disable interrupts, clear when interrupts are virtually enabled. Can be + modified by logical instructions without affecting the Carry flag. + + (*) CCR.ICC2.C [Carry flag] + + Clear to indicate hardware interrupts are really disabled, set otherwise. + + +What happens is this: + + (1) Normal kernel-mode operation. + + ICC2.Z is 0, ICC2.C is 1. + + (2) An interrupt occurs. The exception prologue examines ICC2.Z and determines that nothing needs + doing. This is done simply with an unlikely BEQ instruction. + + (3) The interrupts are disabled (local_irq_disable) + + ICC2.Z is set to 1. + + (4) If interrupts were then re-enabled (local_irq_enable): + + ICC2.Z would be set to 0. + + A TIHI #2 instruction (trap #2 if condition HI - Z==0 && C==0) would be used to trap if + interrupts were now virtually enabled, but physically disabled - which they're not, so the + trap isn't taken. The kernel would then be back to state (1). + + (5) An interrupt occurs. The exception prologue examines ICC2.Z and determines that the interrupt + shouldn't actually have happened. It jumps aside, and there disabled interrupts by setting + PSR.PIL to 14 and then it clears ICC2.C. + + (6) If interrupts were then saved and disabled again (local_irq_save): + + ICC2.Z would be shifted into the save variable and masked off (giving a 1). + + ICC2.Z would then be set to 1 (thus unchanged), and ICC2.C would be unaffected (ie: 0). + + (7) If interrupts were then restored from state (6) (local_irq_restore): + + ICC2.Z would be set to indicate the result of XOR'ing the saved value (ie: 1) with 1, which + gives a result of 0 - thus leaving ICC2.Z set. + + ICC2.C would remain unaffected (ie: 0). + + A TIHI #2 instruction would be used to again assay the current state, but this would do + nothing as Z==1. + + (8) If interrupts were then enabled (local_irq_enable): + + ICC2.Z would be cleared. ICC2.C would be left unaffected. Both flags would now be 0. + + A TIHI #2 instruction again issued to assay the current state would then trap as both Z==0 + [interrupts virtually enabled] and C==0 [interrupts really disabled] would then be true. + + (9) The trap #2 handler would simply enable hardware interrupts (set PSR.PIL to 0), set ICC2.C to + 1 and return. + +(10) Immediately upon returning, the pending interrupt would be taken. + +(11) The interrupt handler would take the path of actually processing the interrupt (ICC2.Z is + clear, BEQ fails as per step (2)). + +(12) The interrupt handler would then set ICC2.C to 1 since hardware interrupts are definitely + enabled - or else the kernel wouldn't be here. + +(13) On return from the interrupt handler, things would be back to state (1). + +This trap (#2) is only available in kernel mode. In user mode it will result in SIGILL. diff --git a/arch/frv/Makefile b/arch/frv/Makefile index 90c0fb8d9dc..d163747d17c 100644 --- a/arch/frv/Makefile +++ b/arch/frv/Makefile @@ -81,7 +81,7 @@ endif # -

It nicely complements my previous fix already in linus' tree. The only thing missing now is that the external CRT will not be activated at neofb init when external-only is selected, either by register read or module/kernel parameter. Testing was done on a Dell Latitude CPi-A/NM2200 chip. Previous behaviour: - before booting linux, set the preferred display config X via FN+F8 - boot linux, neofb stores the register values in a private variable - change the display config to Y via keystroke - leave the machine in peace until display is blanked - touching any key will result in display config X being restored - booting up, the BIOS will acknowledge config Y, though... Current behaviour: At the time of unblanking, config Y is honoured because we now read back register contents instead of just overwriting them with outdated values.

This breaks SNAT of non-unicast packets to non-local addresses because the packet is routed as incoming packet and no neighbour entry is bound to the dst_entry. In general, it seems to be a bad idea to replace the dst_entry after the packet was already sent to the output routine because its state might not match what's expected. This patch changes the xfrm lookup in POST_ROUTING to re-use the original dst_entry without routing the packet again. This means no policy routing can be used for transport mode transforms (which keep the original route) when packets are SNATed to match the policy, but it looks like the best we can do for now.

The first fix (now in 2.6.15) broke the delay loop into smaller, non-preemptible chunks, reenabling preemption between the chunks. This fix is flawed in that the total udelay is computed to be the sum of just the non-premptible while-loop pieces, i.e., not counting the time spent in the interim preemptible periods. If an interrupt or a migration occurs during one of these interim periods, then that time is invisible and only serves to lengthen the effective udelay(). This new fix backs out the current flawed fix and returns to a simple udelay(), fully preemptible and interruptible. It implements two simple alternative udelay() routines: one a default generic version that uses ia64_get_itc(), and the other an sn-specific version that uses that platform's RTC.

This patch directs these packets to the original output path instead. Since the packets have already passed the POST_ROUTING hook, but need to start at the beginning of the original output path which includes another POST_ROUTING invocation, a flag is added to the IPCB to indicate that the packet was rerouted and doesn't need to pass the POST_ROUTING hook again.

Due to this, the logic could not be verified at all and I tried some bogus checks which are completely stupid. - Second, the LCD status bit will always be set to zero when the backlight has been turned off. Reading the value back during unblank will disable the LCD unconditionally, regardless of the state it is supposed to be in, since we set it to zero beforehand. So this is what we do now: - create a new variable in struct neofb_par, and use that to determine whether to read back registers (initialized to true) - before actually blanking the screen, read back the register to sense any possible change made through Fn key combo - use proper neoUnlock() / neoLock() to actually read something - every call to neofb_blank() determines if we read back next time: blanking disables readback, unblanking (FB_BLANK_UNBLANK) enables it This should give us a nice and clean state machine. Has been thoroughly tested on a Dell Latitude CPiA / NM220 Chip docked to a C/Dock2 with attached CRT in all possible combinations of LCD/CRT on/off. I changed the config via Fn key, let the console blank, unblanked by keypress - works flawlessly. Signed-off-by: Christian Trefzer Cc: "Antonino A.

Tsirkin" Date: Wed, 15 Feb 2006 15:17:39 -0800 Subject: [PATCH 1296/1843] [PATCH] add asm-generic/mman.h Make new MADV_REMOVE, MADV_DONTFORK, MADV_DOFORK consistent across all arches. The idea is to make it possible to use them portably even before distros include them in libc headers. Move common flags to asm-generic/mman.h Signed-off-by: Michael S.

When falling back, the driver should also indicate that it is switching to Shared Key mode by setting exclude_unencrypted. 2) Initial authentication modes were apparently wrong in some cases, causing the driver to attempt Shared Key authentication mode when in fact the access point didn't support that mode or even had WEP disabled. The driver should set the correct initial authentication mode based on wep_is_on and exclude_unencrypted. 3) Authentication response packets from the access point in Open System mode were getting ignored because the driver was expecting the sequence number of a Shared Key mode response. The patch separates the OS and SK mode handling to provide the correct behavior. Signed-off-by: Dan Williams Signed-off-by: John W.

The value returned is a fixed-point number in 52.12 format in nanoseconds. The reason for this format is that it gives the full precision that the timekeeping code is using internally. The motivation for this is to fix a problem that has arisen on 32-bit powerpc in that the value returned by do_gettimeofday drifts apart from xtime if NTP is being used. PowerPC is now using a lockless do_gettimeofday based on reading the timebase register and performing some simple arithmetic. (This method of getting the time is also exported to userspace via the VDSO.) However, the factor and offset it uses were calculated based on the nominal tick length and weren't being adjusted when NTP varied the tick length. Note that 64-bit powerpc has had the lockless do_gettimeofday for a long time now. It also had an extremely hairy routine that got called from the 32-bit compat routine for adjtimex, which adjusted the factor and offset according to what it thought the timekeeping code was going to do. Not only was this only called if a 32-bit task did adjtimex (i.e. not if a 64-bit task did adjtimex), it was also duplicating computations from kernel/timer.c and it wasn't clear that it was (still) correct. The simple solution is to ask the timekeeping code how long the current jiffy will be on each timer interrupt, after calling do_timer. If this jiffy will be a different length from the last one, we then need to compute new values for the factor and offset used in the lockless do_gettimeofday. In this way we can keep xtime and do_gettimeofday in sync, even when NTP is varying the tick length. Note that when adjtimex varies the tick length, it almost always introduces the variation from the next tick on. The only case I could see where adjtimex would vary the length of the current tick is when an old-style adjtime adjustment is being cancelled. (It's not clear to me why the adjustment has to be cancelled immediately rather than from the next tick on.) Thus I don't see any real need for a hook in adjtimex; the rare case of an old-style adjustment being cancelled can be fixed up at the next tick.

This deadlock occurs when a file is removed from an ext2 file system which was mounted with the "sync" mount option. The problem is that ext2_xattr_delete_inode() was invoking the routine, sync_dirty_buffer(), using a buffer head which was previously locked via lock_buffer(). The first thing that sync_dirty_buffer() does is to lock the buffer head that it was passed. It does this via lock_buffer(). Oops. The solution is to unlock the buffer head in ext2_xattr_delete_inode() before invoking sync_dirty_buffer(). This makes the code in ext2_xattr_delete_inode() obey the same locking rules as all other callers of sync_dirty_buffer() in the ext2 file system implementation.

The time spent there differs from boot to boot. Also the calculated costs differ a lot. I've seen differences by up to a factor of 15 (yes, factor not percent). Also I doubt that making these measurements make much sense on a completely virtualized architecture where you cannot tell how much cpu time you will get anyway. So introduce the CONFIG_DEFAULT_MIGRATION_COST method for an architecture to set the scheduler migration costs. This turns off automatic detection of migration costs. Makes sense on virtual platforms, where migration costs are hard to measure accurately.

In smp_setup_cpu_possible_map() cpu_present_map is set to the same value as cpu_possible_map. Especially that means that bits in the present map will be set for cpus that are not present. This will cause a slow down in the initial cpu_up() loop in smp_init() since trying to take cpus online that aren't present takes a while. Fix this by setting only bits for present cpus in cpu_present_map and set cpu_present_map to cpu_possible_map in smp_cpus_done().

This involves getting the timebase and performing some simple arithmetic to convert it to seconds and microseconds. However, the factor and offset used there weren't being updated when NTP varied the tick length using adjtimex. 64-bit didn't notice the problem because it had a hook in the 32-bit adjtimex compat routine that attempted to work out what the generic timekeeping code would do and alter the factor and offset to match. However, that code was very complex and it wasn't clear that it still matched what the generic code would do. Now we use the generic current_tick_length() routine that was recently added to check that the current tick will be as long as we expect; if not we recompute the factor and offset. This keeps gettimeofday and xtime in sync. In addition we check that gettimeofday hasn't got ahead of xtime on each timer interrupt; if it has, we resync.

The first one is a buffer overrun in the RX path. We are now using IRDA_SKB_MAX_MTU when initializing the Rx URB. The second one is a potential stack recursion when unplugging the USB dongle. It seems that first we get the Rx URB with a generic error code, and after a while the Rx URB comes again with a "disconnect" error code. Since we are resubmitting the Rx URB immediately after receiving the first error one, we might enter an endless loop. When getting an error Rx URB, the patch defers the Rx URB resubmitting so that it gives us a chance to catch the disconnect one, in case the dongle has juts been unplugged. Tested against 2.6.16-rc2.

We add the vmsize of the children if they * have an own mm. This prevents forking servers to flood the * machine with an endless amount of children */ list_for_each(tsk, &p->children) { struct task_struct *chld; chld = list_entry(tsk, struct task_struct, sibling); if (chld->mm = p->mm && chld->mm) points += chld->mm->total_vm; } The intention is clear: If some server (apache) keeps spawning new children and we run OOM, we want to kill the father rather than picking a child. This -- to some degree -- also helps a bit with getting fork bombs under control, though I'd consider this a desirable side-effect rather than a feature. There's one problem with this: No matter how many or few children there are, if just one of them misbehaves, and all others (including the father) do everything right, we still always kill the whole family. This hits in real life; whether it's javascript in konqueror resulting in kdeinit (and thus the whole KDE session) being hit or just a classical server that spawns children. Sidenote: The killer does kill all direct children as well, not only the selected father, see oom_kill_process(). The idea in attached patch is that we do want to account the memory consumption of the (direct) children to the father -- however not fully. This maintains the property that fathers with too many children will still very likely be picked, whereas a single misbehaving child has the chance to be picked by the OOM killer. In the patch I account only half (rounded up) of the children's vm_size to the parent. This means that if one child eats more mem than the rest of the family, it will be picked, otherwise it's still the father and thus the whole family that gets selected. This is heuristics -- we could debate whether accounting for a fourth would be better than for half of it. Or -- if people would consider it worth the trouble -- make it a sysctl. For now I sticked to accounting for half, which should IMHO be a significant improvement. The patch does one more thing: As users tend to be irritated by the choice of killed processes (mainly because the children are killed first, despite some of them having a very low OOM score), I added some more output: The selected (father) process will be reported first and it's oom_score printed to syslog. Description: Only account for half of children's vm size in oom score calculation This should still give the parent enough point in case of fork bombs. If any child however has more than 50% of the vm size of all children together, it'll get a higher score and be elected. This patch also makes the kernel display the oom_score.

If the page allocator is not able to find enough memory then that does not mean that overall system memory is low. In particular going postal and more or less randomly shooting at processes is not likely going to help the situation but may just lead to suicide (the whole system coming down). It is better to signal to the process that no memory exists given the constraints that the process (or the configuration of the process) has placed on the allocation behavior. The process may be killed but then the sysadmin or developer can investigate the situation. The solution is similar to what we do when running out of hugepages. This patch adds a check before we kill processes. At that point performance considerations do not matter much so we just scan the zonelist and reconstruct a list of nodes. If the list of nodes does not contain all online nodes then this is a constrained allocation and we should kill the current process.

In the previous implementation, a lockup rarely caused at sys_tas() routine in SMP environment. > > The problem is that touching *addr will generate an oops if that page isn't > > paged in. If we convert it to use get_user() then that's an improvement, > > but we must not run get_user() under spinlock or local_irq_disable(). I rewrote sys_tas() routine by using "lock -> unlock" instructions, and utilizing the m32r's interrupt handling characteristics; the m32r processor can accept interrupts only at the 32-bit instruction boundary. So, the "unlock" instruction can be executed continuously after the "lock" instruction execution without any interruptions. In addition, to solve such a page_fault problem, I use a fixup code like get_user(). And, as for the kernel lockup problem, we found that a calling do_page_fault() routine with disabling interrupts might cause a lockup at flush_tlb_others(), because we checked a completion of IPI handler's operations in a spin-locked critical section. Therefore, by using "lock -> unlock" code, we can implement the sys_tas() rouitine without disabling interrupts explicitly, then no lockups would happen at flush_tlb_others(), I hope. Compile check and some working test in SMP environment have done.

Replace it by mpol=policy:nodelist. And it was broken: a nodelist is a comma-separated list of numbers and ranges; the mount options are a comma-separated list of token=values. Whoops, blindly strsep'ing on commas doesn't work so well: since we've no numeric tokens, and unlikely to add them, use that to distinguish. Move the mpol= parsing to shmem_parse_mpol under CONFIG_NUMA, reject all its options as invalid if not NUMA. /proc shows MPOL_PREFERRED as "prefer", so use that name for the policy instead of "preferred". Enforce that mpol=default has no nodelist; that mpol=prefer has one node only; that mpol=bind has a nodelist; but let mpol=interleave use node_online_map if no nodelist given.

Some older versions of HAL still depend on these events to detect when a new device has been mounted. These events are not correctly emitted, and are broken by design, and so, should not be relied upon by any future program. Instead, the /proc/mounts file should be polled to properly detect this kind of event. A feature-removal-schedule.txt entry has been added, noting when this interface will be removed from the kernel.

Since the core only selects addresses which are guaranteed to be out of the "physical range" as per OHCI 1.1, this patch also fixes an old bug: OHCI controllers which implement a writeable PhysicalUpperBound register included sbp2's status FIFO in the physical range. That way sbp2 was never notified of a succesful login and always failed after timeout. Affected OHCI host adapters include ALi and Fujitsu controllers. As another side effect of this patch, the status FIFO is no longer located in a range for which OHCI chips perform "posted writes". Each status write now requires a response subaction. But since large data transfers involve only few status writes, there is no measurable decrease of I/O throughput. What's more, the status FIFO is now safe from potential host bus errors. Nevertheless, posted writes could be re-enabled by extensions to the ARM features of the 1394 stack.

This is because the first packet is used to resolve ARP entries. Even though the ARP entry may be resolved (I tried by setting a static ARP entry for a host i was pinging from), it gets overwritten by virtue of having the netdevice disabling ARP. Subsequent packets go out fine with correct dstMAC address (which may be why people have ignored reporting this issue). To cut the story short: the culprit code is in net/ethernet/eth.c::eth_header() ---- /* * Anyway, the loopback-device should never use this function... */ if (dev->flags & (IFF_LOOPBACK|IFF_NOARP)) { memset(eth->h_dest, 0, dev->addr_len); return ETH_HLEN; } if(daddr) { memcpy(eth->h_dest,daddr,dev->addr_len); return ETH_HLEN; } ---- Note how the h_dest is being reset when device has IFF_NOARP. As a note: All devices including loopback pass a daddr. loopback in fact passes a 0 all the time ;-> This means i can delete the check totaly or i can remove the IFF_NOARP Alexey says: -------------------- I think, it was me who did this crap. It was so long ago I do not remember why it was made. I remember some troubles with dummy device. It tried to resolve addresses, apparently, without success and generated errors instead of blackholing. I think the problem was eventually solved at neighbour level. After some thinking I suspect the deletion of this chunk could change behaviour of some parts which do not use neighbour cache f.e. packet socket. I think safer approach would be to move this chunk after if (daddr). And the possibility to remove this completely could be analyzed later. -------------------- Patch updated with Alexey's safer suggestions.

On some machines the ppc64_pft_size calculation is broken because ppc64_pft_size is not set.

If tty_buffer_request_room() gets called prior to that thread running -- which is likely in this loop in hvc_poll(), it would set the active flag in the tty buffer and consequently flush_to_ldisc() would ignore it. The result is that input on the hvc console is not processed. This fix calls tty_flip_buffer_push (and flags the tty as "low_latency"). The push to the ldisc thus happens synchronously.

When the pages are allocated it is not clear which of the out of place pages will be moved to the new pages. So we cannot specify an address as needed by alloc_page_vma(). This causes problem for MPOL_INTERLEAVE which will currently allocate the pages on the first node of the set. If mbind is used with vma that has the policy of MPOL_INTERLEAVE then the interleaving of pages may be destroyed. This patch fixes that by generating a fake address for each alloc_page_vma which will result is a distribution of pages as prescribed by MPOL_INTERLEAVE. Lee also noted that the sequence of nodes for the new pages seems to be inverted. So we also invert the way the lists of pages for migration are build.

There's also a subtle source of error in that the boot time CPU now uses cpu_gdt_table (which is actually the GDT for booting CPUs in head.S). This patch fixes both problems by making GDT descriptors themselves allocated from a per_cpu area and switching to them in cpu_init(), which now means that cpu_gdt_table is exclusively used for booting CPUs again.

The name. Linux does not follow symlinks, POSIX requires it does. Even if somebody thinks this is a good default behavior we cannot change this because it would break the ABI. But the fact remains that some application might want this behavior. We have one chance to help implementing this without breaking the behavior. For this we could use the new linkat interface which would need a new flags parameter. If the new parameter is AT_SYMLINK_FOLLOW the new behavior could be invoked. I do not want to introduce such a patch now. But we could add the parameter now, just don't use it. The patch below would do this. Can we get this late patch applied before the release more or less fixes the syscall API?

This causes builds with CONFIG_HOTPLUG_CPU to fail. In addition, on Intel processors with cpuid level > 4, it causes intel_cacheinfo.c to reference uninitialized data that should have been set up by the initcall in topology.c which calls register_cpu. This causes a kernel panic on boot on newer Intel processors. Moving topology.c to arch/i386/kernel fixes both of these problems. Thanks to Dan Hecht for finding and fixing this problem.

This patch implements the workaround. This errata results in lock up and doesn't trigger if m15w workaround is in effect. We stopped applying m15w to 3512 and 3114 in 2.6.14-rc1 which makes 3512/3114 lock up with some drives on all kernel versions since 2.6.14-rc1 upto now (2.6.16-rc4).

This changed in 2.6.16 and now gart_xxx() functions are only called if gart is enabled. Therefore, uses of no_iommu in the GART code are no longer necessary and can be removed. Also, it removes double deceleration of no_iommu and force_iommu in pci.h and proto.h, by removing the deceleration in pci.h. Lastly, end_pfn off by one error.

In particular laptops with C2/C3 support often don't let it tick during idle, which makes it useless. There were also some other bugs that made the apicmaintimer often not used at all. I tried some other experiments - running timer over RTC and some other things but they didn't really work well neither. I rechecked the specs now and it turns out this simple change is actually enough to avoid the double ticks on the ATI systems. We just turn off IRQ 0 in the 8254 and only route it directly using the IO-APIC. I tested it on a few ATI systems and it worked there. In fact it worked on all chipsets (NVidia, Intel, AMD, ATI) I tried it on. According to the ACPI spec routing should always work through the IO-APIC so I think it's the correct thing to do anyways (and most of the old gunk in check_timer should be thrown away for x86-64). But for 2.6.16 it's best to do a fairly minimal change: - Use the known to be working everywhere-but-ATI IRQ0 both over 8254 and IO-APIC setup everywhere - Except on ATI disable IRQ0 in the 8254 - Remove the code to select apicmaintimer on ATI chipsets - Add some boot options to allow to override this (just paranoia) In 2.6.17 I hope to switch the default over to this for everybody.

A recent change requires cpu_possible_map to be initialized before smp_sched_init() but most MIPS platforms were initializing their processors in the prom_prepare_cpus callback of smp_prepare_cpus. The simple fix of calling prom_prepare_cpus from one of the earlier SMP initialization hooks doesn't work well either since IPIs may require init_IRQ() to have completed, so bit the bullet and split prom_prepare_cpus into two initialization functions, plat_smp_setup which is called early from setup_arch and plat_prepare_cpus called where prom_prepare_cpus used to be called.

However, after thinking about it for a bit we can adjust the checksums without using this post_input stuff at all. The crucial point is that only the inner-most NAT-T SA needs to be considered when adjusting checksums. What's more, the checksum adjustment comes down to a single u32 due to the linearity of IP checksums. We just happen to have a spare u32 lying around in our skb structure :) When ip_summed is set to CHECKSUM_NONE on input, the value of skb->csum is currently unused. All we have to do is to make that the checksum adjustment and voila, there goes all the post_input and decap structures!

(4c55130b2aa93370f1bf52d2304394e91cf8ee39) Later we changed iSeries_hpte_insert to cope with the bolting case, and called that instead from create_pte_mapping() (which was renamed to htab_bolt_mapping) (3c726f8dee6f55e96475574e9f645327e461884c). Unfortunately that change introduced a subtle bug, where we pass an absolute address to iSeries_hpte_insert() where it expects a physical address. This leads to us calling phys_to_abs() twice on the physical address, which is seriously bogus. This only causes a problem if the absolute address from the first translation can be looked up again in the chunk_map, which depends on the size and layout of memory. I've seen it fail on one box, but not others. The minimal fix is to pass the physical address to iSeries_hpte_insert(). For 2.6.17 we should make phys_to_abs() BUG if we try to double-translate an address.

Turns out the deferred slice expiry logic is buggy, so remove that for now. We could be left with an idle queue that would never wake up. So kill that logic, always expire immediately. Also fix a potential timer race condition. Patch looks bigger than it is, because it moves a function.

When booting an opposite byte sex kernel (e.g. an LE kernel from BE RedBoot) the current MTD driver fails to handle the partition table and therefore is unable to generate the correct partition map for the flash. So far as I am aware this problem is ARM specific, because only ARM supports software change of the CPU (memory system) byte sex, however the partition table parsing is in generic MTD code. The patch below has been tested on NSLU2 (an IXP4XX based system) with a patch, 10-ixp4xx-copy-from.patch (submitted to linux-arm-kernel - it's ARM specific) required to make the maps/ixp4xx.c driver work with an LE kernel. Builds of the patched system are in the 'unstable' release of OpenSlug and UcSlugC available from www.nslu2-linux.org. These builds are BE, the archives at www.nslu2-linux.org and www.handhelds.org (see monotone.vanille.de) can be built LE (currently DISTRO targets nslu-ltu.conf for LE thumb uclibc (32 bit kernel) and nslu2-lau.conf, nslu2-lag.conf for LE arm uclibc/glibc) and this patch has been tested extensively will both BE and LE systems on the NSLU2 (including swapping between BE and LE by reflashing from both RedBoot and Linux). The patch recognises that the FIS directory (the partition table) is byte-reversed by examining the partition table size, which is known to be one erase block (this is an assumption made elsewhere in redboot.c). If the size matches the erase block after byte swapping the value then byte-reversal is assumed, if not no further action is taken. The patched code is fail safe; should redboot.c be changed to support a partition table with a modified size field the test will fail and the partition table will be assumed to have the host byte sex. If byte-reversal is detected the patch byte swaps the remainder of the 32 bit fields in the copy of the table; this copy is then used to set up the MTD partition map.

In the old pcmcia-cs config file, this card is listed with the comment "not specific enough". The last entry in the axnet_ids has the same comment. They are disabled, and for good reason as it was originally identified by the MANFID, and that is shared with several cards that use both the pcnet_cs driver and axnet_cs driver. I tried my AMB8110 with pcnet_cs, and found that it works fine, and I cannot find a reason for either, except that the old config file recommended axnet_cs.

Our previous approach called for aggressive flushing of the dcache resulting in several problems (including wierd cwd behavior when running /bin/pwd). This patch dramatically simplifies our handling of this fid management. Fids will not be clunked as promptly, but the new approach is more functionally correct. We now clunk un-open fids only when their dentry ref_count reaches 0 (and d_delete is called). Another simplification is we no longer seek to match fids to the process-id or uid of the action initiator. The uid-matching will need to be revisited when we fix the security model.

Unfortunately, by doing so, they would trigger a bug in their matching algorithm causing them to attach to the wrong bus, thus triggering issues with the i2c core and breaking the thermal driver. This patch fixes the probing issue (so that they will work when a windfarm port is done to these machines) and also prevents for now windfarm to load at all on these machines that still use therm_pm72 to avoid wasting resources.

When treeids on mutiple mounted shares match and we find the wrong match first, we searched for the wrong cached files to send oplock break response for which usually meant that no matching file was found and thus the server would have to timeout the notification. Oplock break timeout is about 20 seconds on some servers so this could cause significantly slower performance on file open calls in a few cases (in particular when multiple shares are mounted from multiple servers, tree ids match, and we have a cached file which is later opened multiple times). This was the most important of the bugs that was found and fixed at Connectathon (interoperability testing event) this week.

Gunderson reported: - For some reason, it detects the 9845 as a 9735 -- it appears this is simply related to the ordering in parport_serial_pci_tbl[]. If we move the 9845 up above the 9735, it prints out 9710:9845, but no change in behaviour. (We didn't find out why this was the case; we left it alone since it didn't affect our problem.) - The card has no parallel port (at least no physical ones), yet it reports (via its subsystem ID of 0x0014) one parallel port and four serial ports. The probe for the parallel port fails, and the driver just aborts. Thus, it doesn't find the serial ports. Fix the debugging code to use dev_dbg, but don't bother displaying the PCI ID of the detected board (that's accessible via other means.) Also, arrange for parport_register() to return 0 even if it finds no ports.

Numa_maps can now also support huge pages. Fixes: 1. More compact format. Only display fields if they contain additional information. 2. Always display information for all vmas. The old numa_maps did not display vma with no mapped entries. This was a bit confusing because page migration removes ptes for file backed vmas. After page migration a part of the vmas vanished. 3. Rename maxref to maxmap. This is the maximum mapcount of all the pages in a vma and may be used as an indicator as to how many processes may be using a certain vma. 4. Include the ability to scan over huge page vmas. New items shown: dirty Number of pages in a vma that have either the dirty bit set in the page_struct or in the pte. file= The file backing the pages if any stack Stack area heap Heap area huge Huge page area. The number of pages shows is the number of huge pages not the regular sized pages. swapcache Number of pages with swap references. Must be >0 in order to be shown. active Number of active pages. Only displayed if different from the number of pages mapped. writeback Number of pages under writeback. Only displayed if >0.

However, smaps uses page_count for this, so it will return a false positive for every page that is mapped by just that one process, which is also in pagecache or swapcache. There are false positive situations for anonymous pages not in swapcache as well: - page reclaim, migration - get_user_pages (eg. direct-io, ptrace) Use page_mapcount instead, to count the number of mappings to the page. Use vm_normal_page so that weird things like /dev/mem aren't counted either.

In other words, the noerror behaviour would apply to the next system call where we had to reschedule or deliver a signal, which is not necessarily the current system call. * 32-bit wasn't doing the call to ptrace_notify in the syscall exit path when the _TIF_SINGLESTEP bit was set. * _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and _TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set by system calls. I took it out of _TIF_USER_WORK_MASK. * On 64-bit, _TIF_RESTOREALL wasn't causing the non-volatile registers to be restored (unless perhaps a signal was delivered or the syscall was traced or single-stepped). Thus the non-volatile registers weren't restored on exit from a signal handler. We probably got away with it mostly because signal handlers written in C wouldn't alter the non-volatile registers. * On 32-bit I simplified the code and made it more like 64-bit by making the syscall exit path jump to ret_from_except to handle preemption and signal delivery. * 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was set - but I think because of that 32-bit was actually restoring the non-volatile registers on exit from a signal handler. * I changed the order of enabling interrupts and saving the non-volatile registers before calling do_syscall_trace_leave; now we enable interrupts first.

It also adds 4 new mount options: uid/gid=forget and uid/gid=ignore. Without any options the id in core and on disk always match. Giving uid/gid=nnn specifies a default ID to be used in core when the on disk ID is -1. uid/gid=ignore forces the in core ID to allways be used no matter what the on disk ID is. uid/gid=forget forces the on disk ID to always be written out as -1. The use of these options allows you to override ownerships on a disk or disable ownwership information from being written, allowing the media to be used portably between different computers and possibly different users without permissions issues that would require root to correct.

There are two types of controls - number of completed RCU updates invoked in a batch (blimit) and monitoring for high rate of incoming RCUs on a cpu (qhimark, qlowmark). By default, the per-cpu batch limit is set to a small value. If the input RCU rate exceeds the high watermark, we do two things - force quiescent state on all cpus and set the batch limit of the CPU to INTMAX. Setting batch limit to INTMAX forces all finished RCUs to be processed in one shot. If we have more than INTMAX RCUs queued up, then we have bigger problems anyway. Once the incoming queued RCUs fall below the low watermark, the batch limit is set to the default. Signed-off-by: Dipankar Sarma Cc: "Paul E. McKenney" Cc: "David S.

Tested on both x86_64 and powerpc. The way we do file struct accounting is not very suitable for batched freeing. For scalability reasons, file accounting was constructor/destructor based. This meant that nr_files was decremented only when the object was removed from the slab cache. This is susceptible to slab fragmentation. With RCU based file structure, consequent batched freeing and a test program like Serge's, we just speed this up and end up with a very fragmented slab - llm22:~ # cat /proc/sys/fs/file-nr 587730 0 758844 At the same time, I see only a 2000+ objects in filp cache. The following patch I fixes this problem. This patch changes the file counting by removing the filp_count_lock. Instead we use a separate percpu counter, nr_files, for now and all accesses to it are through get_nr_files() api. In the sysctl handler for nr_files, we populate files_stat.nr_files before returning to user. Counting files as an when they are created and destroyed (as opposed to inside slab) allows us to correctly count open files with RCU. Signed-off-by: Dipankar Sarma Cc: "Paul E.

In that case the accessed bit or dirty is set on an zeroed pte which leads the VM to conclude that this is a swap pte. This may lead to - Messages from the vm like swap_free: Bad swap file entry 4000000000000000 - Processes being aborted swap_dup: Bad swap file entry 4000000000000000 VM: killing process .... Page migration is particular suitable for the creation of this race since it needs to remove and restore page table entries. The fix here is to check for the present bit and simply not update the pte if the page is not present anymore. If the page is not present then the fault handler should run next which will take care of the problem by bringing the page back and then mark the page dirty or move it onto the active list.

This is because they route it to both and the result is anded together and the CPU ends up processing it twice. This patch changes check_timer to disable the 8254 routing for interrupt 0. I think it would be safe on all chipsets actually (i tested it on a couple and it worked everywhere) and Windows seems to do it in a similar way, but to be conservative this patch only enables this mode on ATI (and adds options to enable/disable too) Ported over from a similar x86-64 change. I reused the ACPI earlyquirk infrastructure for the ATI bridge check, but tweaked it a bit to work even without ACPI. Inspired by a patch from Chuck Ebbert, but redone.
