This sort of program +is often used on HPC clusters to schedule access to the cluster as a +whole. The cgroup freezer uses cgroups to describe the set of tasks to +be started/stopped by the batch job management system. It also provides +a means to start and stop the tasks composing the job. + + The cgroup freezer will also be useful for checkpointing running groups +of tasks. The freezer allows the checkpoint code to obtain a consistent +image of the tasks by attempting to force the tasks in a cgroup into a +quiescent state.

This also allows the checkpointed tasks to be +migrated between nodes in a cluster by copying the gathered information +to another node and restarting the tasks there. + + Sequences of SIGSTOP and SIGCONT are not always sufficient for stopping +and resuming tasks in userspace. Both of these signals are observable +from within the tasks we wish to freeze. While SIGSTOP cannot be caught, +blocked, or ignored it can be seen by waiting or ptracing parent tasks. +SIGCONT is especially unsuitable since it can be caught by the task.

Address ranges are no more - supported either, define each individual address separately. - SENSORS_INSMOD_ becomes I2C_CLIENT_INSMOD_. - -* [Client data] Get rid of sysctl_id. Try using standard names for - register values (for example, temp_os becomes temp_max). You're - still relatively free here, but you *have* to follow the standard - names for sysfs files (see the Sysctl section below). - -* [Function prototypes] The detect functions loses its flags - parameter. Sysctl (e.g. lm75_temp) and miscellaneous functions - are off the list of prototypes. This usually leaves five - prototypes: - static int lm75_attach_adapter(struct i2c_adapter *adapter); - static int lm75_detect(struct i2c_adapter *adapter, int address, - int kind); - static void lm75_init_client(struct i2c_client *client); - static int lm75_detach_client(struct i2c_client *client); - static struct lm75_data lm75_update_device(struct device *dev); - -* [Sysctl] All sysctl stuff is of course gone (defines, ctl_table - and functions). Instead, you have to define show and set functions for - each sysfs file. Only define set for writable values. Take a look at an - existing 2.6 driver for details (it87 for example).

Don't forget to properly set err before - jumping to error labels.

Move the driver initialization before any - sysfs file creation. - Register the client with the hwmon class (using hwmon_device_register) - if applicable. - Drop client->id. - Drop any 24RF08 corruption prevention you find, as this is now done - at the i2c-core level, and doing it twice voids it. - Don't add I2C_CLIENT_ALLOW_USE to client->flags, it's the default now. - -* [Init] Limits must not be set by the driver (can be done later in - user-space). Chip should not be reset default (although a module - parameter may be used to force it), and initialization should be - limited to the strictly necessary steps. - -* [Detach] Remove the call to i2c_deregister_entry. Do not log an - error message if i2c_detach_client fails, as i2c-core will now do - it for you. - Unregister from the hwmon class if applicable. - -* [Update] The function prototype changed, it is now - passed a device structure, which you have to convert to a client - using to_i2c_client(dev). The update function should return a - pointer to the client data. - Don't access client->data directly, use i2c_get_clientdata(client) - instead. - Use time_after() instead of direct jiffies comparison. - -* [Interface] Make sure there is a MODULE_LICENSE() line, at the bottom - of the file (after MODULE_AUTHOR() and MODULE_DESCRIPTION(), in this - order). - -* [Driver] The flags field of the i2c_driver structure is gone. - I2C_DF_NOTIFY is now the default behavior. - The i2c_driver structure has a driver member, which is itself a - structure, those name member should be initialized to a driver name - string. i2c_driver itself has no name member anymore. - -* [Driver model] Instead of shutdown or reboot notifiers, provide a - shutdown() method in your driver. - -* [Power management] Use the driver model suspend() and resume() - callbacks instead of the obsolete pm_register() calls. - -Coding policy: - -* [Copyright] Use (C), not (c), for copyright. - -* [Debug/log] Get rid of #ifdef DEBUG/#endif constructs whenever you - can.

Introduction + ~~~~~~~~~~~~ + +Currently the Linux Elantech touchpad driver is aware of two different +hardware versions unimaginatively called version 1 and version 2. Version 1 +is found in "older" laptops and uses 4 bytes per packet. Version 2 seems to +be introduced with the EeePC and uses 6 bytes per packet. + +The driver tries to support both hardware versions and should be compatible +with the Xorg Synaptics touchpad driver and its graphical configuration +utilities. + +Additionally the operation of the touchpad can be altered by adjusting the +contents of some of its internal registers. These registers are represented +by the driver as sysfs entries under /sys/bus/serio/drivers/psmouse/serio? +that can be read from and written to. + +Currently only the registers for hardware version 1 are somewhat understood. +Hardware version 2 seems to use some of the same registers but it is not +known whether the bits in the registers represent the same thing or might +have changed their meaning. + +On top of that, some register settings have effect only when the touchpad is +in relative mode and not in absolute mode. As the Linux Elantech touchpad +driver always puts the hardware into absolute mode not all information +mentioned below can be used immediately. But because there is no freely +available Elantech documentation the information is provided here anyway for +completeness sake. + + +///////////////////////////////////////////////////////////////////////////// + + +2. Extra knobs + ~~~~~~~~~~~ + +Currently the Linux Elantech touchpad driver provides two extra knobs under +/sys/bus/serio/drivers/psmouse/serio? for the user. + +* debug + + Turn different levels of debugging ON or OFF. + + By echoing "0" to this file all debugging will be turned OFF. + + Currently a value of "1" will turn on some basic debugging and a value of + "2" will turn on packet debugging. For hardware version 1 the default is + OFF. For version 2 the default is "1". + + Turning packet debugging on will make the driver dump every packet + received to the syslog before processing it. Be warned that this can + generate quite a lot of data! + +* paritycheck + + Turns parity checking ON or OFF. + + By echoing "0" to this file parity checking will be turned OFF. Any + non-zero value will turn it ON. For hardware version 1 the default is ON. + For version 2 the default it is OFF. + + Hardware version 1 provides basic data integrity verification by + calculating a parity bit for the last 3 bytes of each packet. The driver + can check these bits and reject any packet that appears corrupted. Using + this knob you can bypass that check. + + It is not known yet whether hardware version 2 provides the same parity + bits. Hence checking is disabled by default. Currently even turning it on + will do nothing. + + +///////////////////////////////////////////////////////////////////////////// + + +3.

The parity used is even parity which means that the parity bit = 1 +if the data over which the parity is calculated is 1 and the parity bit = 0 +if the data over which the parity is calculated is 0.

A quick analysis: +for the column parity we use the par variable. When extending to 32 bits +we can in the end easily calculate p0 and p1 from it. +(because par now consists of 4 bytes, contributing to rp1, rp0, rp1, rp0 +respectively) +also rp2 and rp3 can be easily retrieved from par as rp3 covers the +first two bytes and rp2 the last two bytes. + +Note that of course now the loop is executed only 64 times (256/4). +And note that care must taken wrt byte ordering.

It was my gut +feeling that in the next steps I would obtain additional gain from it. + +The next step was triggered by the fact that par contains the xor of all +bytes and rp4 and rp5 each contain the xor of half of the bytes. +So in effect par = rp4 ^ rp5. But as xor is commutative we can also say +that rp5 = par ^ rp4. So no need to keep both rp4 and rp5 around. We can +eliminate rp5 (or rp4, but I already foresaw another optimisation). +The same holds for rp6/7, rp8/9, rp10/11 rp12/13 and rp14/15. + + +Attempt 5 +========= + +Effectively so all odd digit rp assignments in the loop were removed. +This included the else clause of the if statements. +Of course after the loop we need to correct things by adding code like: + rp5 = par ^ rp4; +Also the initial assignments (rp5 = 0; etc) could be removed. +Along the line I also removed the initialisation of rp0/1/2/3. + + +Analysis 5 +========== + +Measurements showed this was a good move. The run-time roughly halved +compared with attempt 4 with 4 times unrolled, and we only require 1/3rd +of the processor time compared to the current code in the linux kernel. + +However, still I thought there was more. I didn't like all the if +statements. Why not keep a running parity and only keep the last if +statement.

In the last 3 statements is is added to par and, if needed, +to rp12 and rp14. + +While making the changes I also found that I could exploit that tmppar +contains the running parity for this iteration. So instead of having: +rp4 ^= cur; rp6 = cur; +I removed the rp6 = cur; statement and did rp6 ^= tmppar; on next +statement. A similar change was done for rp8 and rp10 + + +Analysis 6 +========== + +Measuring this code again showed big gain. When executing the original +linux code 1 million times, this took about 1 second on my system. +(using time to measure the performance). After this iteration I was back +to 0.075 sec. Actually I had to decide to start measuring over 10 +million interations in order not to loose too much accuracy. This one +definitely seemed to be the jackpot! + +There is a little bit more room for improvement though. There are three +places with statements: +rp4 ^= cur; rp6 ^= cur; +It seems more efficient to also maintain a variable rp4_6 in the while +loop; This eliminates 3 statements per loop. Of course after the loop we +need to correct by adding: + rp4 ^= rp4_6; + rp6 ^= rp4_6 +Furthermore there are 4 sequential assingments to rp8. This can be +encoded slightly more efficient by saving tmppar before those 4 lines +and later do rp8 = rp8 ^ tmppar ^ notrp8; +(where notrp8 is the value of rp8 before those 4 lines). +Again a use of the commutative property of xor. +Time for a new test! + + +Attempt 7 +========= + +The new code now looks like: + + for (i = 0; i < 4; i++) + { + cur = *bp++; tmppar = cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= tmppar; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp8 ^= tmppar; + + cur = *bp++; tmppar ^= cur; rp4_6 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; rp10 ^= tmppar; + + notrp8 = tmppar; + cur = *bp++; tmppar ^= cur; rp4_6 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; + rp8 = rp8 ^ tmppar ^ notrp8; + + cur = *bp++; tmppar ^= cur; rp4_6 ^= cur; + cur = *bp++; tmppar ^= cur; rp6 ^= cur; + cur = *bp++; tmppar ^= cur; rp4 ^= cur; + cur = *bp++; tmppar ^= cur; + + par ^= tmppar; + if ((i & 0x1) == 0) rp12 ^= tmppar; + if ((i & 0x2) == 0) rp14 ^= tmppar; + } + rp4 ^= rp4_6; + rp6 ^= rp4_6; + + +Not a big change, but every penny counts :-) + + +Analysis 7 +========== + +Acutally this made things worse. Not very much, but I don't want to move +into the wrong direction. Maybe something to investigate later. Could +have to do with caching again. + +Guess that is what there is to win within the loop. Maybe unrolling one +more time will help. I'll keep the optimisations from 7 for now. + + +Attempt 8 +========= + +Unrolled the loop one more time. + + +Analysis 8 +========== + +This makes things worse. Let's stick with attempt 6 and continue from there. +Although it seems that the code within the loop cannot be optimised +further there is still room to optimize the generation of the ecc codes. +We can simply calcualate the total parity. If this is 0 then rp4 = rp5 +etc. If the parity is 1, then rp4 = !rp5; +But if rp4 = rp5 we do not need rp5 etc. We can just write the even bits +in the result byte and then do something like + code[0] |= (code[0] << 1); +Lets test this. + + +Attempt 9 +========= + +Changed the code but again this slightly degrades performance. Tried all +kind of other things, like having dedicated parity arrays to avoid the +shift after parity[rp7] << 7; No gain. +Change the lookup using the parity array by using shift operators (e.g. +replace parity[rp7] << 7 with: +rp7 ^= (rp7 << 4); +rp7 ^= (rp7 << 2); +rp7 ^= (rp7 << 1); +rp7 &= 0x80; +No gain. + +The only marginal change was inverting the parity bits, so we can remove +the last three invert statements. + +Ah well, pity this does not deliver more. Then again 10 million +iterations using the linux driver code takes between 13 and 13.5 +seconds, whereas my code now takes about 0.73 seconds for those 10 +million iterations. So basically I've improved the performance by a +factor 18 on my system. Not that bad. Of course on different hardware +you will get different results. No warranties! + +But of course there is no such thing as a free lunch. The codesize almost +tripled (from 562 bytes to 1434 bytes). Then again, it is not that much. + + +Correcting errors +================= + +For correcting errors I again used the ST application note as a starter, +but I also peeked at the existing code. +The algorithm itself is pretty straightforward. Just xor the given and +the calculated ecc. If all bytes are 0 there is no problem. If 11 bits +are 1 we have one correctable bit error. If there is 1 bit 1, we have an +error in the given ecc code. +It proved to be fastest to do some table lookups. Performance gain +introduced by this is about a factor 2 on my system when a repair had to +be done, and 1% or so if no repair had to be done. +Code size increased from 330 bytes to 686 bytes for this function. +(gcc 4.2, -O3) + + +Conclusion +========== + +The gain when calculating the ecc is tremendous. Om my development hardware +a speedup of a factor of 18 for ecc calculation was achieved. On a test on an +embedded system with a MIPS core a factor 7 was obtained. +On a test with a Linksys NSLU2 (ARMv5TE processor) the speedup was a factor +5 (big endian mode, gcc 4.1.2, -O3) +For correction not much gain could be obtained (as bitflips are rare). Then +again there are also much less cycles spent there. + +It seems there is not much more gain possible in this, at least when +programmed in C. Of course it might be possible to squeeze something more +out of it with an assembler program, but due to pipeline behaviour etc +this is very tricky (at least for intel hw). + +Author: Frans Meulenbroeks +Copyright (C) 2008 Koninklijke Philips Electronics NV. diff --git a/Documentation/networking/.gitignore b/Documentation/networking/.gitignore new file mode 100644 index 0000000000000000000000000000000000000000..286a5680f49051bd9a4abb3dac827af97a1d8f3e --- /dev/null +++ b/Documentation/networking/.gitignore @@ -0,0 +1 @@ +ifenslave diff --git a/Documentation/networking/dmfe.txt b/Documentation/networking/dmfe.txt index b1b7499dd9d33703f431f96710d523a16d0757a1..8006c227fda25fbd150e183a622b94afd9defd86 100644 --- a/Documentation/networking/dmfe.txt +++ b/Documentation/networking/dmfe.txt @@ -60,6 +60,6 @@ Tobias Ringstrom : Current Maintainer Contributors: Marcelo Tosatti -Alan Cox +Alan Cox Jeff Garzik Vojtech Pavlik diff --git a/Documentation/pcmcia/.gitignore b/Documentation/pcmcia/.gitignore new file mode 100644 index 0000000000000000000000000000000000000000..53d081336757477c26021a9ead4fd0cd5434e4b8 --- /dev/null +++ b/Documentation/pcmcia/.gitignore @@ -0,0 +1 @@ +crc32hash diff --git a/Documentation/powerpc/booting-without-of.txt b/Documentation/powerpc/booting-without-of.txt index de4063cb4fdc0ad6abea29d766cae78616837311..02ea9a971b8e5a7b0b33ebcf7e8f56be7c36ac1c 100644 --- a/Documentation/powerpc/booting-without-of.txt +++ b/Documentation/powerpc/booting-without-of.txt @@ -1917,6 +1917,8 @@ platforms are moved over to use the flattened-device-tree model. inverse clock polarity (CPOL) mode - spi-cpha - (optional) Empty property indicating device requires shifted clock phase (CPHA) mode + - spi-cs-high - (optional) Empty property indicating device requires + chip select active high SPI example for an MPC5200 SPI bus: spi@f00 { diff --git a/Documentation/powerpc/dts-bindings/fsl/board.txt b/Documentation/powerpc/dts-bindings/fsl/board.txt index 74ae6f1cd2d6e3cdb313295f9d0fc55124583ec2..81a917ef96e9afbeb609fd6984f8f0eaa1b316d2 100644 --- a/Documentation/powerpc/dts-bindings/fsl/board.txt +++ b/Documentation/powerpc/dts-bindings/fsl/board.txt @@ -2,13 +2,13 @@ Required properties: - - device_type : Should be "board-control" + - compatible : Should be "fsl,-bcsr" - reg : Offset and length of the register set for the device Example: bcsr@f8000000 { - device_type = "board-control"; + compatible = "fsl,mpc8360mds-bcsr"; reg = ; }; diff --git a/Documentation/scheduler/00-INDEX b/Documentation/scheduler/00-INDEX index fc234d093fbf175f8a78dabc3d8ce141f74799ec..aabcc3a089baf66c2dc10210017e0ca6f23199b0 100644 --- a/Documentation/scheduler/00-INDEX +++ b/Documentation/scheduler/00-INDEX @@ -4,8 +4,6 @@ sched-arch.txt - CPU Scheduler implementation hints for architecture specific code. sched-coding.txt - reference for various scheduler-related methods in the O(1) scheduler. -sched-design.txt - - goals, design and implementation of the Linux O(1) scheduler. sched-design-CFS.txt - goals, design and implementation of the Complete Fair Scheduler. sched-domains.txt diff --git a/Documentation/scheduler/sched-design-CFS.txt b/Documentation/scheduler/sched-design-CFS.txt index 9d8eb553884c130cc16f5c50eaeb4e6ca73dbab6..eb471c7a905eda60bc83cbf9eeb03e807356606b 100644 --- a/Documentation/scheduler/sched-design-CFS.txt +++ b/Documentation/scheduler/sched-design-CFS.txt @@ -92,7 +92,7 @@ other HZ detail.

Glossary + + + Introduction + +UWB is a wide-band communication protocol that is to serve also as the +low-level protocol for others (much like TCP sits on IP). Currently +these others are Wireless USB and TCP/IP, but seems Bluetooth and +Firewire/1394 are coming along. + +UWB uses a band from roughly 3 to 10 GHz, transmitting at a max of +~-41dB (or 0.074 uW/MHz--geography specific data is still being +negotiated w/ regulators, so watch for changes). That band is divided in +a bunch of ~1.5 GHz wide channels (or band groups) composed of three +subbands/subchannels (528 MHz each). Each channel is independent of each +other, so you could consider them different "busses". Initially this +driver considers them all a single one. + +Radio time is divided in 65536 us long /superframes/, each one divided +in 256 256us long /MASs/ (Media Allocation Slots), which are the basic +time/media allocation units for transferring data. At the beginning of +each superframe there is a Beacon Period (BP), where every device +transmit its beacon on a single MAS. The length of the BP depends on how +many devices are present and the length of their beacons. + +Devices have a MAC (fixed, 48 bit address) and a device (changeable, 16 +bit address) and send periodic beacons to advertise themselves and pass +info on what they are and do. They advertise their capabilities and a +bunch of other stuff. + +The different logical parts of this driver are: + + * + + *UWB*: the Ultra-Wide-Band stack -- manages the radio and + associated spectrum to allow for devices sharing it. Allows to + control bandwidth assingment, beaconing, scanning, etc + + * + + *WUSB*: the layer that sits on top of UWB to provide Wireless USB. + The Wireless USB spec defines means to control a UWB radio and to + do the actual WUSB. + + + HWA: Host Wire adapters, your Wireless USB dongle + +WUSB also defines a device called a Host Wire Adaptor (HWA), which in +mere terms is a USB dongle that enables your PC to have UWB and Wireless +USB. The Wireless USB Host Controller in a HWA looks to the host like a +[Wireless] USB controller connected via USB (!) + +The HWA itself is broken in two or three main interfaces: + + * + + *RC*: Radio control -- this implements an interface to the + Ultra-Wide-Band radio controller. The driver for this implements a + USB-based UWB Radio Controller to the UWB stack. + + * + + *HC*: the wireless USB host controller. It looks like a USB host + whose root port is the radio and the WUSB devices connect to it. + To the system it looks like a separate USB host. The driver (will) + implement a USB host controller (similar to UHCI, OHCI or EHCI) + for which the root hub is the radio...To reiterate: it is a USB + controller that is connected via USB instead of PCI. + + * + + *WINET*: some HW provide a WiNET interface (IP over UWB). This + package provides a driver for it (it looks like a network + interface, winetX). The driver detects when there is a link up for + their type and kick into gear. + + + DWA: Device Wired Adaptor, a Wireless USB hub for wired devices + +These are the complement to HWAs. They are a USB host for connecting +wired devices, but it is connected to your PC connected via Wireless +USB. To the system it looks like yet another USB host. To the untrained +eye, it looks like a hub that connects upstream wirelessly. + +We still offer no support for this; however, it should share a lot of +code with the HWA-RC driver; there is a bunch of factorization work that +has been done to support that in upcoming releases. + + + WHCI: Wireless Host Controller Interface, the PCI WUSB host adapter + +This is your usual PCI device that implements WHCI. Similar in concept +to EHCI, it allows your wireless USB devices (including DWAs) to connect +to your host via a PCI interface. As in the case of the HWA, it has a +Radio Control interface and the WUSB Host Controller interface per se. + +There is still no driver support for this, but will be in upcoming +releases. + + + The UWB stack + +The main mission of the UWB stack is to keep a tally of which devices +are in radio proximity to allow drivers to connect to them. As well, it +provides an API for controlling the local radio controllers (RCs from +now on), such as to start/stop beaconing, scan, allocate bandwidth, etc. + + + Devices and hosts: the basic structure + +The main building block here is the UWB device (struct uwb_dev). For +each device that pops up in radio presence (ie: the UWB host receives a +beacon from it) you get a struct uwb_dev that will show up in +/sys/class/uwb and in /sys/bus/uwb/devices. + +For each RC that is detected, a new struct uwb_rc is created. In turn, a +RC is also a device, so they also show in /sys/class/uwb and +/sys/bus/uwb/devices, but at the same time, only radio controllers show +up in /sys/class/uwb_rc. + + * + + [*] The reason for RCs being also devices is that not only we can + see them while enumerating the system device tree, but also on the + radio (their beacons and stuff), so the handling has to be + likewise to that of a device. + +Each RC driver is implemented by a separate driver that plugs into the +interface that the UWB stack provides through a struct uwb_rc_ops. The +spec creators have been nice enough to make the message format the same +for HWA and WHCI RCs, so the driver is really a very thin transport that +moves the requests from the UWB API to the device [/uwb_rc_ops->cmd()/] +and sends the replies and notifications back to the API +[/uwb_rc_neh_grok()/]. Notifications are handled to the UWB daemon, that +is chartered, among other things, to keep the tab of how the UWB radio +neighborhood looks, creating and destroying devices as they show up or +dissapear. + +Command execution is very simple: a command block is sent and a event +block or reply is expected back. For sending/receiving command/events, a +handle called /neh/ (Notification/Event Handle) is opened with +/uwb_rc_neh_open()/. + +The HWA-RC (USB dongle) driver (drivers/uwb/hwa-rc.c) does this job for +the USB connected HWA. Eventually, drivers/whci-rc.c will do the same +for the PCI connected WHCI controller. + + + Host Controller life cycle + +So let's say we connect a dongle to the system: it is detected and +firmware uploaded if needed [for Intel's i1480 +/drivers/uwb/ptc/usb.c:ptc_usb_probe()/] and then it is reenumerated. +Now we have a real HWA device connected and +/drivers/uwb/hwa-rc.c:hwarc_probe()/ picks it up, that will set up the +Wire-Adaptor environment and then suck it into the UWB stack's vision of +the world [/drivers/uwb/lc-rc.c:uwb_rc_add()/]. + + * + + [*] The stack should put a new RC to scan for devices + [/uwb_rc_scan()/] so it finds what's available around and tries to + connect to them, but this is policy stuff and should be driven + from user space. As of now, the operator is expected to do it + manually; see the release notes for documentation on the procedure. + +When a dongle is disconnected, /drivers/uwb/hwa-rc.c:hwarc_disconnect()/ +takes time of tearing everything down safely (or not...). + + + On the air: beacons and enumerating the radio neighborhood + +So assuming we have devices and we have agreed for a channel to connect +on (let's say 9), we put the new RC to beacon: + + * + + $ echo 9 0 > /sys/class/uwb_rc/uwb0/beacon + +Now it is visible. If there were other devices in the same radio channel +and beacon group (that's what the zero is for), the dongle's radio +control interface will send beacon notifications on its +notification/event endpoint (NEEP). The beacon notifications are part of +the event stream that is funneled into the API with +/drivers/uwb/neh.c:uwb_rc_neh_grok()/ and delivered to the UWBD, the UWB +daemon through a notification list. + +UWBD wakes up and scans the event list; finds a beacon and adds it to +the BEACON CACHE (/uwb_beca/). If he receives a number of beacons from +the same device, he considers it to be 'onair' and creates a new device +[/drivers/uwb/lc-dev.c:uwbd_dev_onair()/]. Similarly, when no beacons +are received in some time, the device is considered gone and wiped out +[uwbd calls periodically /uwb/beacon.c:uwb_beca_purge()/ that will purge +the beacon cache of dead devices]. + + + Device lists + +All UWB devices are kept in the list of the struct bus_type uwb_bus. + + + Bandwidth allocation + +The UWB stack maintains a local copy of DRP availability through +processing of incoming *DRP Availability Change* notifications. This +local copy is currently used to present the current bandwidth +availability to the user through the sysfs file +/sys/class/uwb_rc/uwbx/bw_avail. In the future the bandwidth +availability information will be used by the bandwidth reservation +routines. + +The bandwidth reservation routines are in progress and are thus not +present in the current release. When completed they will enable a user +to initiate DRP reservation requests through interaction with sysfs. DRP +reservation requests from remote UWB devices will also be handled. The +bandwidth management done by the UWB stack will include callbacks to the +higher layers will enable the higher layers to use the reservations upon +completion. [Note: The bandwidth reservation work is in progress and +subject to change.] + + + Wireless USB Host Controller drivers + +*WARNING* This section needs a lot of work! + +As explained above, there are three different types of HCs in the WUSB +world: HWA-HC, DWA-HC and WHCI-HC. + +HWA-HC and DWA-HC share that they are Wire-Adapters (USB or WUSB +connected controllers), and their transfer management system is almost +identical. So is their notification delivery system. + +HWA-HC and WHCI-HC share that they are both WUSB host controllers, so +they have to deal with WUSB device life cycle and maintenance, wireless +root-hub + +HWA exposes a Host Controller interface (HWA-HC 0xe0/02/02). This has +three endpoints (Notifications, Data Transfer In and Data Transfer +Out--known as NEP, DTI and DTO in the code). + +We reserve UWB bandwidth for our Wireless USB Cluster, create a Cluster +ID and tell the HC to use all that. Then we start it. This means the HC +starts sending MMCs. + + * + + The MMCs are blocks of data defined somewhere in the WUSB1.0 spec + that define a stream in the UWB channel time allocated for sending + WUSB IEs (host to device commands/notifications) and Device + Notifications (device initiated to host). Each host defines a + unique Wireless USB cluster through MMCs. Devices can connect to a + single cluster at the time. The IEs are Information Elements, and + among them are the bandwidth allocations that tell each device + when can they transmit or receive. + +Now it all depends on external stimuli. + +*New device connection* + +A new device pops up, it scans the radio looking for MMCs that give out +the existence of Wireless USB channels. Once one (or more) are found, +selects which one to connect to. Sends a /DN_Connect/ (device +notification connect) during the DNTS (Device Notification Time +Slot--announced in the MMCs + +HC picks the /DN_Connect/ out (nep module sends to notif.c for delivery +into /devconnect/). This process starts the authentication process for +the device. First we allocate a /fake port/ and assign an +unauthenticated address (128 to 255--what we really do is +0x80 | fake_port_idx). We fiddle with the fake port status and /khubd/ +sees a new connection, so he moves on to enable the fake port with a reset. + +So now we are in the reset path -- we know we have a non-yet enumerated +device with an unauthorized address; we ask user space to authenticate +(FIXME: not yet done, similar to bluetooth pairing), then we do the key +exchange (FIXME: not yet done) and issue a /set address 0/ to bring the +device to the default state. Device is authenticated. + +From here, the USB stack takes control through the usb_hcd ops. khubd +has seen the port status changes, as we have been toggling them. It will +start enumerating and doing transfers through usb_hcd->urb_enqueue() to +read descriptors and move our data. + +*Device life cycle and keep alives* + +Everytime there is a succesful transfer to/from a device, we update a +per-device activity timestamp. If not, every now and then we check and +if the activity timestamp gets old, we ping the device by sending it a +Keep Alive IE; it responds with a /DN_Alive/ pong during the DNTS (this +arrives to us as a notification through +devconnect.c:wusb_handle_dn_alive(). If a device times out, we +disconnect it from the system (cleaning up internal information and +toggling the bits in the fake hub port, which kicks khubd into removing +the rest of the stuff). + +This is done through devconnect:__wusb_check_devs(), which will scan the +device list looking for whom needs refreshing. + +If the device wants to disconnect, it will either die (ugly) or send a +/DN_Disconnect/ that will prompt a disconnection from the system. + +*Sending and receiving data* + +Data is sent and received through /Remote Pipes/ (rpipes). An rpipe is +/aimed/ at an endpoint in a WUSB device. This is the same for HWAs and +DWAs. + +Each HC has a number of rpipes and buffers that can be assigned to them; +when doing a data transfer (xfer), first the rpipe has to be aimed and +prepared (buffers assigned), then we can start queueing requests for +data in or out. + +Data buffers have to be segmented out before sending--so we send first a +header (segment request) and then if there is any data, a data buffer +immediately after to the DTI interface (yep, even the request). If our +buffer is bigger than the max segment size, then we just do multiple +requests. + +[This sucks, because doing USB scatter gatter in Linux is resource +intensive, if any...not that the current approach is not. It just has to +be cleaned up a lot :)]. + +If reading, we don't send data buffers, just the segment headers saying +we want to read segments. + +When the xfer is executed, we receive a notification that says data is +ready in the DTI endpoint (handled through +xfer.c:wa_handle_notif_xfer()). In there we read from the DTI endpoint a +descriptor that gives us the status of the transfer, its identification +(given when we issued it) and the segment number. If it was a data read, +we issue another URB to read into the destination buffer the chunk of +data coming out of the remote endpoint. Done, wait for the next guy. The +callbacks for the URBs issued from here are the ones that will declare +the xfer complete at some point and call it's callback. + +Seems simple, but the implementation is not trivial. + + * + + *WARNING* Old!! + +The main xfer descriptor, wa_xfer (equivalent to a URB) contains an +array of segments, tallys on segments and buffers and callback +information. Buried in there is a lot of URBs for executing the segments +and buffer transfers. + +For OUT xfers, there is an array of segments, one URB for each, another +one of buffer URB. When submitting, we submit URBs for segment request +1, buffer 1, segment 2, buffer 2...etc. Then we wait on the DTI for xfer +result data; when all the segments are complete, we call the callback to +finalize the transfer. + +For IN xfers, we only issue URBs for the segments we want to read and +then wait for the xfer result data. + +*URB mapping into xfers* + +This is done by hwahc_op_urb_[en|de]queue(). In enqueue() we aim an +rpipe to the endpoint where we have to transmit, create a transfer +context (wa_xfer) and submit it. When the xfer is done, our callback is +called and we assign the status bits and release the xfer resources. + +In dequeue() we are basically cancelling/aborting the transfer. We issue +a xfer abort request to the HC, cancell all the URBs we had submitted +and not yet done and when all that is done, the xfer callback will be +called--this will call the URB callback. + + + Glossary + +*DWA* -- Device Wire Adapter + +USB host, wired for downstream devices, upstream connects wirelessly +with Wireless USB. + +*EVENT* -- Response to a command on the NEEP + +*HWA* -- Host Wire Adapter / USB dongle for UWB and Wireless USB + +*NEH* -- Notification/Event Handle + +Handle/file descriptor for receiving notifications or events.

The document attempts to provide the overall +rationale behind this mechanism and the rationale for some of the design +decisions that drove the implementation. The latter design rationale is +discussed in the context of an implementation description. Admittedly, one +can obtain the implementation details--the "what does it do?"--by reading the +code. One hopes that the descriptions below add value by provide the answer +to "why does it do that?". + +Unevictable LRU Infrastructure: + +The Unevictable LRU adds an additional LRU list to track unevictable pages +and to hide these pages from vmscan. This mechanism is based on a patch by +Larry Woodman of Red Hat to address several scalability problems with page +reclaim in Linux. The problems have been observed at customer sites on large +memory x86_64 systems. For example, a non-numal x86_64 platform with 128GB +of main memory will have over 32 million 4k pages in a single zone. When a +large fraction of these pages are not evictable for any reason [see below], +vmscan will spend a lot of time scanning the LRU lists looking for the small +fraction of pages that are evictable. This can result in a situation where +all cpus are spending 100% of their time in vmscan for hours or days on end, +with the system completely unresponsive. + +The Unevictable LRU infrastructure addresses the following classes of +unevictable pages: + ++ page owned by ramfs ++ page mapped into SHM_LOCKed shared memory regions ++ page mapped into VM_LOCKED [mlock()ed] vmas + +The infrastructure might be able to handle other conditions that make pages +unevictable, either by definition or by circumstance, in the future. + + +The Unevictable LRU List + +The Unevictable LRU infrastructure consists of an additional, per-zone, LRU list +called the "unevictable" list and an associated page flag, PG_unevictable, to +indicate that the page is being managed on the unevictable list. The +PG_unevictable flag is analogous to, and mutually exclusive with, the PG_active +flag in that it indicates on which LRU list a page resides when PG_lru is set. +The unevictable LRU list is source configurable based on the UNEVICTABLE_LRU +Kconfig option. + +The Unevictable LRU infrastructure maintains unevictable pages on an additional +LRU list for a few reasons: + +1) We get to "treat unevictable pages just like we treat other pages in the + system, which means we get to use the same code to manipulate them, the + same code to isolate them (for migrate, etc.), the same code to keep track + of the statistics, etc..." [Rik van Riel] + +2) We want to be able to migrate unevictable pages between nodes--for memory + defragmentation, workload management and memory hotplug. The linux kernel + can only migrate pages that it can successfully isolate from the lru lists. + If we were to maintain pages elsewise than on an lru-like list, where they + can be found by isolate_lru_page(), we would prevent their migration, unless + we reworked migration code to find the unevictable pages. + + +The unevictable LRU list does not differentiate between file backed and swap +backed [anon] pages. This differentiation is only important while the pages +are, in fact, evictable. + +The unevictable LRU list benefits from the "arrayification" of the per-zone +LRU lists and statistics originally proposed and posted by Christoph Lameter. + +The unevictable list does not use the lru pagevec mechanism. Rather, +unevictable pages are placed directly on the page's zone's unevictable +list under the zone lru_lock. The reason for this is to prevent stranding +of pages on the unevictable list when one task has the page isolated from the +lru and other tasks are changing the "evictability" state of the page. + + +Unevictable LRU and Memory Controller Interaction + +The memory controller data structure automatically gets a per zone unevictable +lru list as a result of the "arrayification" of the per-zone LRU lists. The +memory controller tracks the movement of pages to and from the unevictable list. +When a memory control group comes under memory pressure, the controller will +not attempt to reclaim pages on the unevictable list. This has a couple of +effects. Because the pages are "hidden" from reclaim on the unevictable list, +the reclaim process can be more efficient, dealing only with pages that have +a chance of being reclaimed. On the other hand, if too many of the pages +charged to the control group are unevictable, the evictable portion of the +working set of the tasks in the control group may not fit into the available +memory. This can cause the control group to thrash or to oom-kill tasks. + + +Unevictable LRU: Detecting Unevictable Pages + +The function page_evictable(page, vma) in vmscan.c determines whether a +page is evictable or not. For ramfs pages and pages in SHM_LOCKed regions, +page_evictable() tests a new address space flag, AS_UNEVICTABLE, in the page's +address space using a wrapper function. Wrapper functions are used to set, +clear and test the flag to reduce the requirement for #ifdef's throughout the +source code. AS_UNEVICTABLE is set on ramfs inode/mapping when it is created. +This flag remains for the life of the inode. + +For shared memory regions, AS_UNEVICTABLE is set when an application +successfully SHM_LOCKs the region and is removed when the region is +SHM_UNLOCKed. Note that shmctl(SHM_LOCK, ...) does not populate the page +tables for the region as does, for example, mlock(). So, we make no special +effort to push any pages in the SHM_LOCKed region to the unevictable list. +Vmscan will do this when/if it encounters the pages during reclaim. On +SHM_UNLOCK, shmctl() scans the pages in the region and "rescues" them from the +unevictable list if no other condition keeps them unevictable. If a SHM_LOCKed +region is destroyed, the pages are also "rescued" from the unevictable list in +the process of freeing them. + +page_evictable() detects mlock()ed pages by testing an additional page flag, +PG_mlocked via the PageMlocked() wrapper. If the page is NOT mlocked, and a +non-NULL vma is supplied, page_evictable() will check whether the vma is +VM_LOCKED via is_mlocked_vma(). is_mlocked_vma() will SetPageMlocked() and +update the appropriate statistics if the vma is VM_LOCKED. This method allows +efficient "culling" of pages in the fault path that are being faulted in to +VM_LOCKED vmas. + + +Unevictable Pages and Vmscan [shrink_*_list()] + +If unevictable pages are culled in the fault path, or moved to the unevictable +list at mlock() or mmap() time, vmscan will never encounter the pages until +they have become evictable again, for example, via munlock() and have been +"rescued" from the unevictable list. However, there may be situations where we +decide, for the sake of expediency, to leave a unevictable page on one of the +regular active/inactive LRU lists for vmscan to deal with. Vmscan checks for +such pages in all of the shrink_{active|inactive|page}_list() functions and +will "cull" such pages that it encounters--that is, it diverts those pages to +the unevictable list for the zone being scanned. + +There may be situations where a page is mapped into a VM_LOCKED vma, but the +page is not marked as PageMlocked. Such pages will make it all the way to +shrink_page_list() where they will be detected when vmscan walks the reverse +map in try_to_unmap(). If try_to_unmap() returns SWAP_MLOCK, shrink_page_list() +will cull the page at that point. + +Note that for anonymous pages, shrink_page_list() attempts to add the page to +the swap cache before it tries to unmap the page. To avoid this unnecessary +consumption of swap space, shrink_page_list() calls try_to_munlock() to check +whether any VM_LOCKED vmas map the page without attempting to unmap the page. +If try_to_munlock() returns SWAP_MLOCK, shrink_page_list() will cull the page +without consuming swap space. try_to_munlock() will be described below. + +To "cull" an unevictable page, vmscan simply puts the page back on the lru +list using putback_lru_page()--the inverse operation to isolate_lru_page()-- +after dropping the page lock. Because the condition which makes the page +unevictable may change once the page is unlocked, putback_lru_page() will +recheck the unevictable state of a page that it places on the unevictable lru +list. If the page has become unevictable, putback_lru_page() removes it from +the list and retries, including the page_unevictable() test. Because such a +race is a rare event and movement of pages onto the unevictable list should be +rare, these extra evictabilty checks should not occur in the majority of calls +to putback_lru_page(). + + +Mlocked Page: Prior Work + +The "Unevictable Mlocked Pages" infrastructure is based on work originally +posted by Nick Piggin in an RFC patch entitled "mm: mlocked pages off LRU". +Nick posted his patch as an alternative to a patch posted by Christoph +Lameter to achieve the same objective--hiding mlocked pages from vmscan. +In Nick's patch, he used one of the struct page lru list link fields as a count +of VM_LOCKED vmas that map the page. This use of the link field for a count +prevented the management of the pages on an LRU list. Thus, mlocked pages were +not migratable as isolate_lru_page() could not find them and the lru list link +field was not available to the migration subsystem. Nick resolved this by +putting mlocked pages back on the lru list before attempting to isolate them, +thus abandoning the count of VM_LOCKED vmas. When Nick's patch was integrated +with the Unevictable LRU work, the count was replaced by walking the reverse +map to determine whether any VM_LOCKED vmas mapped the page. More on this +below. + + +Mlocked Pages: Basic Management + +Mlocked pages--pages mapped into a VM_LOCKED vma--represent one class of +unevictable pages. When such a page has been "noticed" by the memory +management subsystem, the page is marked with the PG_mlocked [PageMlocked()] +flag. A PageMlocked() page will be placed on the unevictable LRU list when +it is added to the LRU. Pages can be "noticed" by memory management in +several places: + +1) in the mlock()/mlockall() system call handlers. +2) in the mmap() system call handler when mmap()ing a region with the + MAP_LOCKED flag, or mmap()ing a region in a task that has called + mlockall() with the MCL_FUTURE flag. Both of these conditions result + in the VM_LOCKED flag being set for the vma. +3) in the fault path, if mlocked pages are "culled" in the fault path, + and when a VM_LOCKED stack segment is expanded. +4) as mentioned above, in vmscan:shrink_page_list() with attempting to + reclaim a page in a VM_LOCKED vma--via try_to_unmap() or try_to_munlock(). + +Mlocked pages become unlocked and rescued from the unevictable list when: + +1) mapped in a range unlocked via the munlock()/munlockall() system calls. +2) munmapped() out of the last VM_LOCKED vma that maps the page, including + unmapping at task exit. +3) when the page is truncated from the last VM_LOCKED vma of an mmap()ed file. +4) before a page is COWed in a VM_LOCKED vma. + + +Mlocked Pages: mlock()/mlockall() System Call Handling + +Both [do_]mlock() and [do_]mlockall() system call handlers call mlock_fixup() +for each vma in the range specified by the call. In the case of mlockall(), +this is the entire active address space of the task. Note that mlock_fixup() +is used for both mlock()ing and munlock()ing a range of memory. A call to +mlock() an already VM_LOCKED vma, or to munlock() a vma that is not VM_LOCKED +is treated as a no-op--mlock_fixup() simply returns. + +If the vma passes some filtering described in "Mlocked Pages: Filtering Vmas" +below, mlock_fixup() will attempt to merge the vma with its neighbors or split +off a subset of the vma if the range does not cover the entire vma. Once the +vma has been merged or split or neither, mlock_fixup() will call +__mlock_vma_pages_range() to fault in the pages via get_user_pages() and +to mark the pages as mlocked via mlock_vma_page(). + +Note that the vma being mlocked might be mapped with PROT_NONE. In this case, +get_user_pages() will be unable to fault in the pages. That's OK. If pages +do end up getting faulted into this VM_LOCKED vma, we'll handle them in the +fault path or in vmscan. + +Also note that a page returned by get_user_pages() could be truncated or +migrated out from under us, while we're trying to mlock it. To detect +this, __mlock_vma_pages_range() tests the page_mapping after acquiring +the page lock. If the page is still associated with its mapping, we'll +go ahead and call mlock_vma_page(). If the mapping is gone, we just +unlock the page and move on. Worse case, this results in page mapped +in a VM_LOCKED vma remaining on a normal LRU list without being +PageMlocked(). Again, vmscan will detect and cull such pages. + +mlock_vma_page(), called with the page locked [N.B., not "mlocked"], will +TestSetPageMlocked() for each page returned by get_user_pages(). We use +TestSetPageMlocked() because the page might already be mlocked by another +task/vma and we don't want to do extra work. We especially do not want to +count an mlocked page more than once in the statistics. If the page was +already mlocked, mlock_vma_page() is done. + +If the page was NOT already mlocked, mlock_vma_page() attempts to isolate the +page from the LRU, as it is likely on the appropriate active or inactive list +at that time. If the isolate_lru_page() succeeds, mlock_vma_page() will +putback the page--putback_lru_page()--which will notice that the page is now +mlocked and divert the page to the zone's unevictable LRU list. If +mlock_vma_page() is unable to isolate the page from the LRU, vmscan will handle +it later if/when it attempts to reclaim the page. + + +Mlocked Pages: Filtering Special Vmas + +mlock_fixup() filters several classes of "special" vmas: + +1) vmas with VM_IO|VM_PFNMAP set are skipped entirely. The pages behind + these mappings are inherently pinned, so we don't need to mark them as + mlocked. In any case, most of the pages have no struct page in which to + so mark the page. Because of this, get_user_pages() will fail for these + vmas, so there is no sense in attempting to visit them. + +2) vmas mapping hugetlbfs page are already effectively pinned into memory. + We don't need nor want to mlock() these pages. However, to preserve the + prior behavior of mlock()--before the unevictable/mlock changes--mlock_fixup() + will call make_pages_present() in the hugetlbfs vma range to allocate the + huge pages and populate the ptes. + +3) vmas with VM_DONTEXPAND|VM_RESERVED are generally user space mappings of + kernel pages, such as the vdso page, relay channel pages, etc. These pages + are inherently unevictable and are not managed on the LRU lists. + mlock_fixup() treats these vmas the same as hugetlbfs vmas. It calls + make_pages_present() to populate the ptes. + +Note that for all of these special vmas, mlock_fixup() does not set the +VM_LOCKED flag. Therefore, we won't have to deal with them later during +munlock() or munmap()--for example, at task exit. Neither does mlock_fixup() +account these vmas against the task's "locked_vm". + +Mlocked Pages: Downgrading the Mmap Semaphore. + +mlock_fixup() must be called with the mmap semaphore held for write, because +it may have to merge or split vmas. However, mlocking a large region of +memory can take a long time--especially if vmscan must reclaim pages to +satisfy the regions requirements. Faulting in a large region with the mmap +semaphore held for write can hold off other faults on the address space, in +the case of a multi-threaded task. It can also hold off scans of the task's +address space via /proc. While testing under heavy load, it was observed that +the ps(1) command could be held off for many minutes while a large segment was +mlock()ed down. + +To address this issue, and to make the system more responsive during mlock()ing +of large segments, mlock_fixup() downgrades the mmap semaphore to read mode +during the call to __mlock_vma_pages_range(). This works fine. However, the +callers of mlock_fixup() expect the semaphore to be returned in write mode. +So, mlock_fixup() "upgrades" the semphore to write mode. Linux does not +support an atomic upgrade_sem() call, so mlock_fixup() must drop the semaphore +and reacquire it in write mode. In a multi-threaded task, it is possible for +the task memory map to change while the semaphore is dropped. Therefore, +mlock_fixup() looks up the vma at the range start address after reacquiring +the semaphore in write mode and verifies that it still covers the original +range. If not, mlock_fixup() returns an error [-EAGAIN]. All callers of +mlock_fixup() have been changed to deal with this new error condition. + +Note: when munlocking a region, all of the pages should already be resident-- +unless we have racing threads mlocking() and munlocking() regions. So, +unlocking should not have to wait for page allocations nor faults of any kind. +Therefore mlock_fixup() does not downgrade the semaphore for munlock(). + + +Mlocked Pages: munlock()/munlockall() System Call Handling + +The munlock() and munlockall() system calls are handled by the same functions-- +do_mlock[all]()--as the mlock() and mlockall() system calls with the unlock +vs lock operation indicated by an argument. So, these system calls are also +handled by mlock_fixup(). Again, if called for an already munlock()ed vma, +mlock_fixup() simply returns. Because of the vma filtering discussed above, +VM_LOCKED will not be set in any "special" vmas. So, these vmas will be +ignored for munlock. + +If the vma is VM_LOCKED, mlock_fixup() again attempts to merge or split off +the specified range. The range is then munlocked via the function +__mlock_vma_pages_range()--the same function used to mlock a vma range-- +passing a flag to indicate that munlock() is being performed. + +Because the vma access protections could have been changed to PROT_NONE after +faulting in and mlocking some pages, get_user_pages() was unreliable for visiting +these pages for munlocking. Because we don't want to leave pages mlocked(), +get_user_pages() was enhanced to accept a flag to ignore the permissions when +fetching the pages--all of which should be resident as a result of previous +mlock()ing. + +For munlock(), __mlock_vma_pages_range() unlocks individual pages by calling +munlock_vma_page(). munlock_vma_page() unconditionally clears the PG_mlocked +flag using TestClearPageMlocked(). As with mlock_vma_page(), munlock_vma_page() +use the Test*PageMlocked() function to handle the case where the page might +have already been unlocked by another task. If the page was mlocked, +munlock_vma_page() updates that zone statistics for the number of mlocked +pages. Note, however, that at this point we haven't checked whether the page +is mapped by other VM_LOCKED vmas. + +We can't call try_to_munlock(), the function that walks the reverse map to check +for other VM_LOCKED vmas, without first isolating the page from the LRU. +try_to_munlock() is a variant of try_to_unmap() and thus requires that the page +not be on an lru list. [More on these below.] However, the call to +isolate_lru_page() could fail, in which case we couldn't try_to_munlock(). +So, we go ahead and clear PG_mlocked up front, as this might be the only chance +we have. If we can successfully isolate the page, we go ahead and +try_to_munlock(), which will restore the PG_mlocked flag and update the zone +page statistics if it finds another vma holding the page mlocked. If we fail +to isolate the page, we'll have left a potentially mlocked page on the LRU. +This is fine, because we'll catch it later when/if vmscan tries to reclaim the +page. This should be relatively rare. + +Mlocked Pages: Migrating Them... + +A page that is being migrated has been isolated from the lru lists and is +held locked across unmapping of the page, updating the page's mapping +[address_space] entry and copying the contents and state, until the +page table entry has been replaced with an entry that refers to the new +page. Linux supports migration of mlocked pages and other unevictable +pages. This involves simply moving the PageMlocked and PageUnevictable states +from the old page to the new page. + +Note that page migration can race with mlocking or munlocking of the same +page. This has been discussed from the mlock/munlock perspective in the +respective sections above. Both processes [migration, m[un]locking], hold +the page locked. This provides the first level of synchronization. Page +migration zeros out the page_mapping of the old page before unlocking it, +so m[un]lock can skip these pages by testing the page mapping under page +lock. + +When completing page migration, we place the new and old pages back onto the +lru after dropping the page lock. The "unneeded" page--old page on success, +new page on failure--will be freed when the reference count held by the +migration process is released. To ensure that we don't strand pages on the +unevictable list because of a race between munlock and migration, page +migration uses the putback_lru_page() function to add migrated pages back to +the lru. + + +Mlocked Pages: mmap(MAP_LOCKED) System Call Handling + +In addition the the mlock()/mlockall() system calls, an application can request +that a region of memory be mlocked using the MAP_LOCKED flag with the mmap() +call. Furthermore, any mmap() call or brk() call that expands the heap by a +task that has previously called mlockall() with the MCL_FUTURE flag will result +in the newly mapped memory being mlocked. Before the unevictable/mlock changes, +the kernel simply called make_pages_present() to allocate pages and populate +the page table. + +To mlock a range of memory under the unevictable/mlock infrastructure, the +mmap() handler and task address space expansion functions call +mlock_vma_pages_range() specifying the vma and the address range to mlock. +mlock_vma_pages_range() filters vmas like mlock_fixup(), as described above in +"Mlocked Pages: Filtering Vmas". It will clear the VM_LOCKED flag, which will +have already been set by the caller, in filtered vmas. Thus these vma's need +not be visited for munlock when the region is unmapped. + +For "normal" vmas, mlock_vma_pages_range() calls __mlock_vma_pages_range() to +fault/allocate the pages and mlock them. Again, like mlock_fixup(), +mlock_vma_pages_range() downgrades the mmap semaphore to read mode before +attempting to fault/allocate and mlock the pages; and "upgrades" the semaphore +back to write mode before returning. + +The callers of mlock_vma_pages_range() will have already added the memory +range to be mlocked to the task's "locked_vm". To account for filtered vmas, +mlock_vma_pages_range() returns the number of pages NOT mlocked. All of the +callers then subtract a non-negative return value from the task's locked_vm. +A negative return value represent an error--for example, from get_user_pages() +attempting to fault in a vma with PROT_NONE access. In this case, we leave +the memory range accounted as locked_vm, as the protections could be changed +later and pages allocated into that region. + + +Mlocked Pages: munmap()/exit()/exec() System Call Handling + +When unmapping an mlocked region of memory, whether by an explicit call to +munmap() or via an internal unmap from exit() or exec() processing, we must +munlock the pages if we're removing the last VM_LOCKED vma that maps the pages. +Before the unevictable/mlock changes, mlocking did not mark the pages in any way, +so unmapping them required no processing. + +To munlock a range of memory under the unevictable/mlock infrastructure, the +munmap() hander and task address space tear down function call +munlock_vma_pages_all(). The name reflects the observation that one always +specifies the entire vma range when munlock()ing during unmap of a region. +Because of the vma filtering when mlocking() regions, only "normal" vmas that +actually contain mlocked pages will be passed to munlock_vma_pages_all(). + +munlock_vma_pages_all() clears the VM_LOCKED vma flag and, like mlock_fixup() +for the munlock case, calls __munlock_vma_pages_range() to walk the page table +for the vma's memory range and munlock_vma_page() each resident page mapped by +the vma. This effectively munlocks the page, only if this is the last +VM_LOCKED vma that maps the page. + + +Mlocked Page: try_to_unmap() + +[Note: the code changes represented by this section are really quite small +compared to the text to describe what happening and why, and to discuss the +implications.] + +Pages can, of course, be mapped into multiple vmas. Some of these vmas may +have VM_LOCKED flag set. It is possible for a page mapped into one or more +VM_LOCKED vmas not to have the PG_mlocked flag set and therefore reside on one +of the active or inactive LRU lists. This could happen if, for example, a +task in the process of munlock()ing the page could not isolate the page from +the LRU. As a result, vmscan/shrink_page_list() might encounter such a page +as described in "Unevictable Pages and Vmscan [shrink_*_list()]". To +handle this situation, try_to_unmap() has been enhanced to check for VM_LOCKED +vmas while it is walking a page's reverse map. + +try_to_unmap() is always called, by either vmscan for reclaim or for page +migration, with the argument page locked and isolated from the LRU. BUG_ON() +assertions enforce this requirement. Separate functions handle anonymous and +mapped file pages, as these types of pages have different reverse map +mechanisms. + + try_to_unmap_anon() + +To unmap anonymous pages, each vma in the list anchored in the anon_vma must be +visited--at least until a VM_LOCKED vma is encountered. If the page is being +unmapped for migration, VM_LOCKED vmas do not stop the process because mlocked +pages are migratable. However, for reclaim, if the page is mapped into a +VM_LOCKED vma, the scan stops. try_to_unmap() attempts to acquire the mmap +semphore of the mm_struct to which the vma belongs in read mode. If this is +successful, try_to_unmap() will mlock the page via mlock_vma_page()--we +wouldn't have gotten to try_to_unmap() if the page were already mlocked--and +will return SWAP_MLOCK, indicating that the page is unevictable. If the +mmap semaphore cannot be acquired, we are not sure whether the page is really +unevictable or not. In this case, try_to_unmap() will return SWAP_AGAIN. + + try_to_unmap_file() -- linear mappings + +Unmapping of a mapped file page works the same, except that the scan visits +all vmas that maps the page's index/page offset in the page's mapping's +reverse map priority search tree. It must also visit each vma in the page's +mapping's non-linear list, if the list is non-empty. As for anonymous pages, +on encountering a VM_LOCKED vma for a mapped file page, try_to_unmap() will +attempt to acquire the associated mm_struct's mmap semaphore to mlock the page, +returning SWAP_MLOCK if this is successful, and SWAP_AGAIN, if not. + + try_to_unmap_file() -- non-linear mappings + +If a page's mapping contains a non-empty non-linear mapping vma list, then +try_to_un{map|lock}() must also visit each vma in that list to determine +whether the page is mapped in a VM_LOCKED vma. Again, the scan must visit +all vmas in the non-linear list to ensure that the pages is not/should not be +mlocked. If a VM_LOCKED vma is found in the list, the scan could terminate. +However, there is no easy way to determine whether the page is actually mapped +in a given vma--either for unmapping or testing whether the VM_LOCKED vma +actually pins the page. + +So, try_to_unmap_file() handles non-linear mappings by scanning a certain +number of pages--a "cluster"--in each non-linear vma associated with the page's +mapping, for each file mapped page that vmscan tries to unmap. If this happens +to unmap the page we're trying to unmap, try_to_unmap() will notice this on +return--(page_mapcount(page) == 0)--and return SWAP_SUCCESS. Otherwise, it +will return SWAP_AGAIN, causing vmscan to recirculate this page. We take +advantage of the cluster scan in try_to_unmap_cluster() as follows: + +For each non-linear vma, try_to_unmap_cluster() attempts to acquire the mmap +semaphore of the associated mm_struct for read without blocking. If this +attempt is successful and the vma is VM_LOCKED, try_to_unmap_cluster() will +retain the mmap semaphore for the scan; otherwise it drops it here. Then, +for each page in the cluster, if we're holding the mmap semaphore for a locked +vma, try_to_unmap_cluster() calls mlock_vma_page() to mlock the page. This +call is a no-op if the page is already locked, but will mlock any pages in +the non-linear mapping that happen to be unlocked. If one of the pages so +mlocked is the page passed in to try_to_unmap(), try_to_unmap_cluster() will +return SWAP_MLOCK, rather than the default SWAP_AGAIN. This will allow vmscan +to cull the page, rather than recirculating it on the inactive list. Again, +if try_to_unmap_cluster() cannot acquire the vma's mmap sem, it returns +SWAP_AGAIN, indicating that the page is mapped by a VM_LOCKED vma, but +couldn't be mlocked. + + +Mlocked pages: try_to_munlock() Reverse Map Scan + +TODO/FIXME: a better name might be page_mlocked()--analogous to the +page_referenced() reverse map walker--especially if we continue to call this +from shrink_page_list(). See related TODO/FIXME below. + +When munlock_vma_page()--see "Mlocked Pages: munlock()/munlockall() System +Call Handling" above--tries to munlock a page, or when shrink_page_list() +encounters an anonymous page that is not yet in the swap cache, they need to +determine whether or not the page is mapped by any VM_LOCKED vma, without +actually attempting to unmap all ptes from the page. For this purpose, the +unevictable/mlock infrastructure introduced a variant of try_to_unmap() called +try_to_munlock(). + +try_to_munlock() calls the same functions as try_to_unmap() for anonymous and +mapped file pages with an additional argument specifing unlock versus unmap +processing. Again, these functions walk the respective reverse maps looking +for VM_LOCKED vmas. When such a vma is found for anonymous pages and file +pages mapped in linear VMAs, as in the try_to_unmap() case, the functions +attempt to acquire the associated mmap semphore, mlock the page via +mlock_vma_page() and return SWAP_MLOCK. This effectively undoes the +pre-clearing of the page's PG_mlocked done by munlock_vma_page() and informs +shrink_page_list() that the anonymous page should be culled rather than added +to the swap cache in preparation for a try_to_unmap() that will almost +certainly fail. + +If try_to_unmap() is unable to acquire a VM_LOCKED vma's associated mmap +semaphore, it will return SWAP_AGAIN. This will allow shrink_page_list() +to recycle the page on the inactive list and hope that it has better luck +with the page next time. + +For file pages mapped into non-linear vmas, the try_to_munlock() logic works +slightly differently. On encountering a VM_LOCKED non-linear vma that might +map the page, try_to_munlock() returns SWAP_AGAIN without actually mlocking +the page. munlock_vma_page() will just leave the page unlocked and let +vmscan deal with it--the usual fallback position. + +Note that try_to_munlock()'s reverse map walk must visit every vma in a pages' +reverse map to determine that a page is NOT mapped into any VM_LOCKED vma. +However, the scan can terminate when it encounters a VM_LOCKED vma and can +successfully acquire the vma's mmap semphore for read and mlock the page. +Although try_to_munlock() can be called many [very many!] times when +munlock()ing a large region or tearing down a large address space that has been +mlocked via mlockall(), overall this is a fairly rare event. In addition, +although shrink_page_list() calls try_to_munlock() for every anonymous page that +it handles that is not yet in the swap cache, on average anonymous pages will +have very short reverse map lists. + +Mlocked Page: Page Reclaim in shrink_*_list() + +shrink_active_list() culls any obviously unevictable pages--i.e., +!page_evictable(page, NULL)--diverting these to the unevictable lru +list. However, shrink_active_list() only sees unevictable pages that +made it onto the active/inactive lru lists. Note that these pages do not +have PageUnevictable set--otherwise, they would be on the unevictable list and +shrink_active_list would never see them. + +Some examples of these unevictable pages on the LRU lists are: + +1) ramfs pages that have been placed on the lru lists when first allocated. + +2) SHM_LOCKed shared memory pages. shmctl(SHM_LOCK) does not attempt to + allocate or fault in the pages in the shared memory region. This happens + when an application accesses the page the first time after SHM_LOCKing + the segment. + +3) Mlocked pages that could not be isolated from the lru and moved to the + unevictable list in mlock_vma_page(). + +3) Pages mapped into multiple VM_LOCKED vmas, but try_to_munlock() couldn't + acquire the vma's mmap semaphore to test the flags and set PageMlocked. + munlock_vma_page() was forced to let the page back on to the normal + LRU list for vmscan to handle. + +shrink_inactive_list() also culls any unevictable pages that it finds +on the inactive lists, again diverting them to the appropriate zone's unevictable +lru list. shrink_inactive_list() should only see SHM_LOCKed pages that became +SHM_LOCKed after shrink_active_list() had moved them to the inactive list, or +pages mapped into VM_LOCKED vmas that munlock_vma_page() couldn't isolate from +the lru to recheck via try_to_munlock(). shrink_inactive_list() won't notice +the latter, but will pass on to shrink_page_list(). + +shrink_page_list() again culls obviously unevictable pages that it could +encounter for similar reason to shrink_inactive_list(). As already discussed, +shrink_page_list() proactively looks for anonymous pages that should have +PG_mlocked set but don't--these would not be detected by page_evictable()--to +avoid adding them to the swap cache unnecessarily. File pages mapped into +VM_LOCKED vmas but without PG_mlocked set will make it all the way to +try_to_unmap(). shrink_page_list() will divert them to the unevictable list when +try_to_unmap() returns SWAP_MLOCK, as discussed above. + +TODO/FIXME: If we can enhance the swap cache to reliably remove entries +with page_count(page) > 2, as long as all ptes are mapped to the page and +not the swap entry, we can probably remove the call to try_to_munlock() in +shrink_page_list() and just remove the page from the swap cache when +try_to_unmap() returns SWAP_MLOCK.
