+ARM TCM (Tightly-Coupled Memory) handling in Linux
+----
+Written by Linus Walleij <linus.walleij@stericsson.com>
+
+Some ARM SoC:s have a so-called TCM (Tightly-Coupled Memory).
+This is usually just a few (4-64) KiB of RAM inside the ARM
+processor.
+
+Due to being embedded inside the CPU The TCM has a
+Harvard-architecture, so there is an ITCM (instruction TCM)
+and a DTCM (data TCM). The DTCM can not contain any
+instructions, but the ITCM can actually contain data.
+The size of DTCM or ITCM is minimum 4KiB so the typical
+minimum configuration is 4KiB ITCM and 4KiB DTCM.
+
+ARM CPU:s have special registers to read out status, physical
+location and size of TCM memories. arch/arm/include/asm/cputype.h
+defines a CPUID_TCM register that you can read out from the
+system control coprocessor. Documentation from ARM can be found
+at http://infocenter.arm.com, search for "TCM Status Register"
+to see documents for all CPUs. Reading this register you can
+determine if ITCM (bit 0) and/or DTCM (bit 16) is present in the
+machine.
+
+There is further a TCM region register (search for "TCM Region
+Registers" at the ARM site) that can report and modify the location
+size of TCM memories at runtime. This is used to read out and modify
+TCM location and size. Notice that this is not a MMU table: you
+actually move the physical location of the TCM around. At the
+place you put it, it will mask any underlying RAM from the
+CPU so it is usually wise not to overlap any physical RAM with
+the TCM.
+
+The TCM memory can then be remapped to another address again using
+the MMU, but notice that the TCM if often used in situations where
+the MMU is turned off. To avoid confusion the current Linux
+implementation will map the TCM 1 to 1 from physical to virtual
+memory in the location specified by the machine.
+
+TCM is used for a few things:
+
+- FIQ and other interrupt handlers that need deterministic
+  timing and cannot wait for cache misses.
+
+- Idle loops where all external RAM is set to self-refresh
+  retention mode, so only on-chip RAM is accessible by
+  the CPU and then we hang inside ITCM waiting for an
+  interrupt.
+
+- Other operations which implies shutting off or reconfiguring
+  the external RAM controller.
+
+There is an interface for using TCM on the ARM architecture
+in <asm/tcm.h>. Using this interface it is possible to:
+
+- Define the physical address and size of ITCM and DTCM.
+
+- Tag functions to be compiled into ITCM.
+
+- Tag data and constants to be allocated to DTCM and ITCM.
+
+- Have the remaining TCM RAM added to a special
+  allocation pool with gen_pool_create() and gen_pool_add()
+  and provice tcm_alloc() and tcm_free() for this
+  memory. Such a heap is great for things like saving
+  device state when shutting off device power domains.
+
+A machine that has TCM memory shall select HAVE_TCM in
+arch/arm/Kconfig for itself, and then the
+rest of the functionality will depend on the physical
+location and size of ITCM and DTCM to be defined in
+mach/memory.h for the machine. Code that needs to use
+TCM shall #include <asm/tcm.h> If the TCM is not located
+at the place given in memory.h it will be moved using
+the TCM Region registers.
+
+Functions to go into itcm can be tagged like this:
+int __tcmfunc foo(int bar);
+
+Variables to go into dtcm can be tagged like this:
+int __tcmdata foo;
+
+Constants can be tagged like this:
+int __tcmconst foo;
+
+To put assembler into TCM just use
+.section ".tcm.text" or .section ".tcm.data"
+respectively.
+
+Example code:
+
+#include <asm/tcm.h>
+
+/* Uninitialized data */
+static u32 __tcmdata tcmvar;
+/* Initialized data */
+static u32 __tcmdata tcmassigned = 0x2BADBABEU;
+/* Constant */

+The name should match [\w.-]+

+in /proc/mounts and /proc/<pid>/cgroups.

+7. Soft limits
+
+Soft limits allow for greater sharing of memory. The idea behind soft limits
+is to allow control groups to use as much of the memory as needed, provided
+
+a. There is no memory contention
+b. They do not exceed their hard limit
+
+When the system detects memory contention or low memory control groups
+are pushed back to their soft limits. If the soft limit of each control
+group is very high, they are pushed back as much as possible to make
+sure that one control group does not starve the others of memory.
+
+Please note that soft limits is a best effort feature, it comes with
+no guarantees, but it does its best to make sure that when memory is
+heavily contended for, memory is allocated based on the soft limit
+hints/setup. Currently soft limit based reclaim is setup such that
+it gets invoked from balance_pgdat (kswapd).
+
+7.1 Interface
+
+Soft limits can be setup by using the following commands (in this example we
+assume a soft limit of 256 megabytes)
+
+# echo 256M > memory.soft_limit_in_bytes
+
+If we want to change this to 1G, we can at any time use
+
+# echo 1G > memory.soft_limit_in_bytes
+
+NOTE1: Soft limits take effect over a long period of time, since they involve
+       reclaiming memory for balancing between memory cgroups
+NOTE2: It is recommended to set the soft limit always below the hard limit,
+       otherwise the hard limit will take precedence.
+
+8. TODO
 
 1. Add support for accounting huge pages (as a separate controller)
 2. Make per-cgroup scanner reclaim not-shared pages first

+================================
+Driver for EP93xx LCD controller
+================================
+
+The EP93xx LCD controller can drive both standard desktop monitors and
+embedded LCD displays. If you have a standard desktop monitor then you
+can use the standard Linux video mode database. In your board file:
+
+	static struct ep93xxfb_mach_info some_board_fb_info = {
+		.num_modes	= EP93XXFB_USE_MODEDB,
+		.bpp		= 16,
+	};
+
+If you have an embedded LCD display then you need to define a video
+mode for it as follows:
+
+	static struct fb_videomode some_board_video_modes[] = {
+		{
+			.name		= "some_lcd_name",
+			/* Pixel clock, porches, etc */
+		},
+	};
+
+Note that the pixel clock value is in pico-seconds. You can use the
+KHZ2PICOS macro to convert the pixel clock value. Most other values
+are in pixel clocks. See Documentation/fb/framebuffer.txt for further
+details.
+
+The ep93xxfb_mach_info structure for your board should look like the
+following:
+
+	static struct ep93xxfb_mach_info some_board_fb_info = {
+		.num_modes	= ARRAY_SIZE(some_board_video_modes),
+		.modes		= some_board_video_modes,
+		.default_mode	= &some_board_video_modes[0],
+		.bpp		= 16,
+	};
+
+The framebuffer device can be registered by adding the following to
+your board initialisation function:
+
+	ep93xx_register_fb(&some_board_fb_info);
+
+=====================
+Video Attribute Flags
+=====================
+
+The ep93xxfb_mach_info structure has a flags field which can be used
+to configure the controller. The video attributes flags are fully
+documented in section 7 of the EP93xx users' guide. The following
+flags are available:
+
+EP93XXFB_PCLK_FALLING		Clock data on the falling edge of the
+				pixel clock. The default is to clock
+				data on the rising edge.
+
+EP93XXFB_SYNC_BLANK_HIGH	Blank signal is active high. By
+				default the blank signal is active low.
+
+EP93XXFB_SYNC_HORIZ_HIGH	Horizontal sync is active high. By
+				default the horizontal sync is active low.
+
+EP93XXFB_SYNC_VERT_HIGH		Vertical sync is active high. By
+				default the vertical sync is active high.
+
+The physical address of the framebuffer can be controlled using the
+following flags:
+
+EP93XXFB_USE_SDCSN0		Use SDCSn[0] for the framebuffer. This
+				is the default setting.
+
+EP93XXFB_USE_SDCSN1		Use SDCSn[1] for the framebuffer.
+
+EP93XXFB_USE_SDCSN2		Use SDCSn[2] for the framebuffer.
+
+EP93XXFB_USE_SDCSN3		Use SDCSn[3] for the framebuffer.
+
+==================
+Platform callbacks
+==================
+
+The EP93xx framebuffer driver supports three optional platform
+callbacks: setup, teardown and blank. The setup and teardown functions
+are called when the framebuffer driver is installed and removed
+respectively. The blank function is called whenever the display is
+blanked or unblanked.
+
+The setup and teardown devices pass the platform_device structure as
+an argument. The fb_info and ep93xxfb_mach_info structures can be
+obtained as follows:
+
+	static int some_board_fb_setup(struct platform_device *pdev)
+	{
+		struct ep93xxfb_mach_info *mach_info = pdev->dev.platform_data;
+		struct fb_info *fb_info = platform_get_drvdata(pdev);
+
+		/* Board specific framebuffer setup */
+	}
+
+======================
+Setting the video mode
+======================
+
+The video mode is set using the following syntax:
+
+	video=XRESxYRES[-BPP][@REFRESH]
+
+If the EP93xx video driver is built-in then the video mode is set on
+the Linux kernel command line, for example:
+
+	video=ep93xx-fb:800x600-16@60
+
+If the EP93xx video driver is built as a module then the video mode is
+set when the module is installed:
+
+	modprobe ep93xx-fb video=320x240
+
+==============
+Screenpage bug
+==============
+
+At least on the EP9315 there is a silicon bug which causes bit 27 of
+the VIDSCRNPAGE (framebuffer physical offset) to be tied low. There is
+an unofficial errata for this bug at:
+	http://marc.info/?l=linux-arm-kernel&m=110061245502000&w=2
+
+By default the EP93xx framebuffer driver checks if the allocated physical
+address has bit 27 set. If it does, then the memory is freed and an
+error is returned. The check can be disabled by adding the following
+option when loading the driver:
+
+      ep93xx-fb.check_screenpage_bug=0
+
+In some cases it may be possible to reconfigure your SDRAM layout to
+avoid this bug. See section 13 of the EP93xx users' guide for details.

+	expects that these hardware features will be ubiquitous in a couple of

+The current implementation is intended for developers only: while it
+does support ordinary file operations on clients we have tested against
+(including the linux client), it is incomplete in ways which may limit
+features unexpectedly, cause known bugs in rare cases, or cause
+interoperability problems with future clients.  Known issues:
+
+	- gss support is questionable: currently mounts with kerberos
+	  from a linux client are possible, but we aren't really
+	  conformant with the spec (for example, we don't use kerberos
+	  on the backchannel correctly).
+	- no trunking support: no clients currently take advantage of
+	  trunking, but this is a mandatory failure, and its use is
+	  recommended to clients in a number of places.  (E.g. to ensure
+	  timely renewal in case an existing connection's retry timeouts
+	  have gotten too long; see section 8.3 of the draft.)
+	  Therefore, lack of this feature may cause future clients to
+	  fail.
+	- Incomplete backchannel support: incomplete backchannel gss
+	  support and no support for BACKCHANNEL_CTL mean that
+	  callbacks (hence delegations and layouts) may not be
+	  available and clients confused by the incomplete
+	  implementation may fail.
+	- Server reboot recovery is unsupported; if the server reboots,
+	  clients may fail.
+	- We do not support SSV, which provides security for shared
+	  client-server state (thus preventing unauthorized tampering
+	  with locks and opens, for example).  It is mandatory for
+	  servers to support this, though no clients use it yet.
+	- Mandatory operations which we do not support, such as
+	  DESTROY_CLIENTID, FREE_STATEID, SECINFO_NO_NAME, and
+	  TEST_STATEID, are not currently used by clients, but will be
+	  (and the spec recommends their uses in common cases), and
+	  clients should not be expected to know how to recover from the
+	  case where they are not supported.  This will eventually cause
+	  interoperability failures.
+
+In addition, some limitations are inherited from the current NFSv4
+implementation:
+
+	- Incomplete delegation enforcement: if a file is renamed or
+	  unlinked, a client holding a delegation may continue to
+	  indefinitely allow opens of the file under the old name.

+Kernel driver power_meter
+=========================
+
+This driver talks to ACPI 4.0 power meters.
+
+Supported systems:
+  * Any recent system with ACPI 4.0.
+    Prefix: 'power_meter'
+    Datasheet: http://acpi.info/, section 10.4.
+
+Author: Darrick J. Wong
+
+Description
+-----------
+
+This driver implements sensor reading support for the power meters exposed in
+the ACPI 4.0 spec (Chapter 10.4).  These devices have a simple set of
+features--a power meter that returns average power use over a configurable
+interval, an optional capping mechanism, and a couple of trip points.  The
+sysfs interface conforms with the specification outlined in the "Power" section
+of Documentation/hwmon/sysfs-interface.
+
+Special Features
+----------------
+
+The power[1-*]_is_battery knob indicates if the power supply is a battery.
+Both power[1-*]_average_{min,max} must be set before the trip points will work.
+When both of them are set, an ACPI event will be broadcast on the ACPI netlink
+socket and a poll notification will be sent to the appropriate
+power[1-*]_average sysfs file.
+
+The power[1-*]_{model_number, serial_number, oem_info} fields display arbitrary
+strings that ACPI provides with the meter.  The measures/ directory contains
+symlinks to the devices that this meter measures.
+
+Some computers have the ability to enforce a power cap in hardware.  If this is
+the case, the power[1-*]_cap and related sysfs files will appear.  When the
+average power consumption exceeds the cap, an ACPI event will be broadcast on
+the netlink event socket and a poll notification will be sent to the
+appropriate power[1-*]_alarm file to indicate that capping has begun, and the
+hardware has taken action to reduce power consumption.  Most likely this will
+result in reduced performance.
+
+There are a few other ACPI notifications that can be sent by the firmware.  In
+all cases the ACPI event will be broadcast on the ACPI netlink event socket as
+well as sent as a poll notification to a sysfs file.  The events are as
+follows:
+
+power[1-*]_cap will be notified if the firmware changes the power cap.
+power[1-*]_interval will be notified if the firmware changes the averaging
+interval.

-Description
------------
-
-This driver implements support for the Fujitsu-Siemens Hermes chip. It is
-described in the 'Register Set Specification BMC Hermes based Systemboard'
-from Fujitsu-Siemens.
-
-The Hermes chip implements a hardware-based system management, e.g. for
-controlling fan speed and core voltage. There is also a watchdog counter on
-the chip which can trigger an alarm and even shut the system down.
-
-The chip provides three temperature values (CPU, motherboard and
-auxiliary), three voltage values (+12V, +5V and battery) and three fans
-(power supply, CPU and auxiliary).
-
-Temperatures are measured in degrees Celsius. The resolution is 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). The value
-can be divided by a programmable divider (1, 2 or 4) which is stored on
-the chip.
-
-Voltage sensors (also known as "in" sensors) report their values in volts.
-
-All values are reported as final values from the driver. There is no need
-for further calculations.
-
-
-Detailed description
---------------------
-
-Below you'll find a single line description of all the bit values. With
-this information, you're able to decode e. g. alarms, wdog, etc. To make
-use of the watchdog, you'll need to set the watchdog time and enable the
-watchdog. After that it is necessary to restart the watchdog time within
-the specified period of time, or a system reset will occur.

-Limitations
------------
-
-* Measuring fan speed
-It seems that the chip counts "ripples" (typical fans produce 2 ripples per
-rotation while VERAX fans produce 18) in a 9-bit register. This register is
-read out every second, then the ripple prescaler (2, 4 or 8) is applied and
-the result is stored in the 8 bit output register. Due to the limitation of
-the counting register to 9 bits, it is impossible to measure a VERAX fan
-properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the
-fan produces 1080 ripples per second which causes the counting register to
-overflow twice, leading to only 186 RPM.
-
-* Measuring input voltages
-in2 ("battery") reports the voltage of the onboard lithium battery and not
-+3.3V from the power supply.
-
-* Undocumented features
-Fujitsu-Siemens Computers has not documented all features of the chip so
-far. Their software, System Guard, shows that there are a still some
-features which cannot be controlled by this implementation.

-Description
------------
-The PCF8574(A) is an 8-bit I/O expander for the I2C bus produced by Philips
-Semiconductors. It is designed to provide a byte I2C interface to up to 16
-separate devices (8 x PCF8574 and 8 x PCF8574A).
-
-This device consists of a quasi-bidirectional port. Each of the eight I/Os
-can be independently used as an input or output. To setup an I/O as an
-input, you have to write a 1 to the corresponding output.
-
-For more informations see the datasheet.
-
-
-Accessing PCF8574(A) via /sys interface
--------------------------------------
-
-The PCF8574(A) is plainly impossible to detect ! Stupid chip.
-So, you have to pass the I2C bus and address of the installed PCF857A
-and PCF8574A devices explicitly to the driver at load time via the
-force=... parameter.
-
-On detection (i.e. insmod, modprobe et al.), directories are being
-created for each detected PCF8574(A):
-
-/sys/bus/i2c/devices/<0>-<1>/
-where <0> is the bus the chip was detected on (e. g. i2c-0)
-and <1> the chip address ([20..27] or [38..3f]):
-
-(example: /sys/bus/i2c/devices/1-0020/)
-
-Inside these directories, there are two files each:
-read and write (and one file with chip name).
-
-The read file is read-only. Reading gives you the current I/O input
-if the corresponding output is set as 1, otherwise the current output
-value, that is to say 0.
-
-The write file is read/write. Writing a value outputs it on the I/O
-port. Reading returns the last written value. As it is not possible
-to read this value from the chip, you need to write at least once to
-this file before you can read back from it.

-About the PCF8575 chip and the pcf8575 kernel driver
-====================================================
-
-The PCF8575 chip is produced by the following manufacturers:
-
-  * Philips NXP
-    http://www.nxp.com/#/pip/cb=[type=product,path=50807/41735/41850,final=PCF8575_3]|pip=[pip=PCF8575_3][0]
-
-  * Texas Instruments
-    http://focus.ti.com/docs/prod/folders/print/pcf8575.html
-
-
-Some vendors sell small PCB's with the PCF8575 mounted on it. You can connect
-such a board to a Linux host via e.g. an USB to I2C interface. Examples of
-PCB boards with a PCF8575:

-
-
-Description
------------
-The PCF8575 chip is a 16-bit I/O expander for the I2C bus. Up to eight of
-these chips can be connected to the same I2C bus. You can find this
-chip on some custom designed hardware, but you won't find it on PC
-motherboards.
-
-The PCF8575 chip consists of a 16-bit quasi-bidirectional port and an I2C-bus
-interface. Each of the sixteen I/O's can be independently used as an input or
-an output. To set up an I/O pin as an input, you have to write a 1 to the
-corresponding output.
-
-For more information please see the datasheet.
-
-
-Detection
----------
-
-There is no method known to detect whether a chip on a given I2C address is
-a PCF8575 or whether it is any other I2C device, so you have to pass the I2C
-bus and address of the installed PCF8575 devices explicitly to the driver at
-load time via the force=... parameter.
-
-/sys interface
---------------
-
-For each address on which a PCF8575 chip was found or forced the following
-files will be created under /sys:
-* /sys/bus/i2c/devices/<bus>-<address>/read
-* /sys/bus/i2c/devices/<bus>-<address>/write
-where bus is the I2C bus number (0, 1, ...) and address is the four-digit
-hexadecimal representation of the 7-bit I2C address of the PCF8575
-(0020 .. 0027).
-
-The read file is read-only. Reading it will trigger an I2C read and will hence
-report the current input state for the pins configured as inputs, and the
-current output value for the pins configured as outputs.
-
-The write file is read-write. Writing a value to it will configure all pins
-as output for which the corresponding bit is zero. Reading the write file will
-return the value last written, or -EAGAIN if no value has yet been written to
-the write file.
-
-On module initialization the configuration of the chip is not changed -- the
-chip is left in the state it was already configured in through either power-up
-or through previous I2C write actions.

+Asus Laptop Extras
+
+Version 0.1
+August 6, 2009
+
+Corentin Chary <corentincj@iksaif.net>
+http://acpi4asus.sf.net/
+
+ This driver provides support for extra features of ACPI-compatible ASUS laptops.
+ It may also support some MEDION, JVC or VICTOR laptops (such as MEDION 9675 or
+ VICTOR XP7210 for example). It makes all the extra buttons generate standard
+ ACPI events that go through /proc/acpi/events and input events (like keyboards).
+ On some models adds support for changing the display brightness and output,
+ switching the LCD backlight on and off, and most importantly, allows you to
+ blink those fancy LEDs intended for reporting mail and wireless status.
+
+This driver supercedes the old asus_acpi driver.
+
+Requirements
+------------
+
+  Kernel 2.6.X sources, configured for your computer, with ACPI support.
+  You also need CONFIG_INPUT and CONFIG_ACPI.
+
+Status
+------
+
+ The features currently supported are the following (see below for
+ detailed description):
+
+ - Fn key combinations
+ - Bluetooth enable and disable
+ - Wlan enable and disable
+ - GPS enable and disable
+ - Video output switching
+ - Ambient Light Sensor on and off
+ - LED control
+ - LED Display control
+ - LCD brightness control
+ - LCD on and off
+
+ A compatibility table by model and feature is maintained on the web
+ site, http://acpi4asus.sf.net/.
+
+Usage
+-----
+
+  Try "modprobe asus_acpi". Check your dmesg (simply type dmesg). You should
+  see some lines like this :
+
+      Asus Laptop Extras version 0.42
+        L2D model detected.
+
+  If it is not the output you have on your laptop, send it (and the laptop's
+  DSDT) to me.
+
+  That's all, now, all the events generated by the hotkeys of your laptop
+  should be reported in your /proc/acpi/event entry. You can check with
+  "acpi_listen".
+
+  Hotkeys are also reported as input keys (like keyboards) you can check
+  which key are supported using "xev" under X11.
+
+  You can get informations on the version of your DSDT table by reading the
+  /sys/devices/platform/asus-laptop/infos entry. If you have a question or a
+  bug report to do, please include the output of this entry.
+
+LEDs
+----
+
+  You can modify LEDs be echoing values to /sys/class/leds/asus::*/brightness :
+    echo 1 >  /sys/class/leds/asus::mail/brightness
+  will switch the mail LED on.
+  You can also know if they are on/off by reading their content and use
+  kernel triggers like ide-disk or heartbeat.
+
+Backlight
+---------
+
+  You can control lcd backlight power and brightness with
+  /sys/class/backlight/asus-laptop/. Brightness Values are between 0 and 15.
+
+Wireless devices
+---------------
+
+  You can turn the internal Bluetooth adapter on/off with the bluetooth entry
+  (only on models with Bluetooth). This usually controls the associated LED.
+  Same for Wlan adapter.
+
+Display switching
+-----------------
+
+  Note: the display switching code is currently considered EXPERIMENTAL.
+
+  Switching works for the following models:
+    L3800C
+    A2500H
+    L5800C
+    M5200N
+    W1000N (albeit with some glitches)
+    M6700R
+    A6JC
+    F3J
+
+  Switching doesn't work for the following:
+    M3700N
+    L2X00D (locks the laptop under certain conditions)
+
+  To switch the displays, echo values from 0 to 15 to
+  /sys/devices/platform/asus-laptop/display. The significance of those values
+  is as follows:
+
+  +-------+-----+-----+-----+-----+-----+

+
+  In most cases, the appropriate displays must be plugged in for the above
+  combinations to work. TV-Out may need to be initialized at boot time.
+
+  Debugging:
+  1) Check whether the Fn+F8 key:
+     a) does not lock the laptop (try disabling CONFIG_X86_UP_APIC or boot with
+        noapic / nolapic if it does)
+     b) generates events (0x6n, where n is the value corresponding to the
+        configuration above)
+     c) actually works
+     Record the disp value at every configuration.
+  2) Echo values from 0 to 15 to /sys/devices/platform/asus-laptop/display.
+     Record its value, note any change. If nothing changes, try a broader range,
+     up to 65535.
+  3) Send ANY output (both positive and negative reports are needed, unless your
+     machine is already listed above) to the acpi4asus-user mailing list.
+
+  Note: on some machines (e.g. L3C), after the module has been loaded, only 0x6n
+  events are generated and no actual switching occurs. In such a case, a line
+  like:
+
+    echo $((10#$arg-60)) > /sys/devices/platform/asus-laptop/display
+
+  will usually do the trick ($arg is the 0000006n-like event passed to acpid).
+
+  Note: there is currently no reliable way to read display status on xxN
+  (Centrino) models.
+
+LED display
+-----------
+
+  Some models like the W1N have a LED display that can be used to display
+  several informations.
+
+  LED display works for the following models:
+    W1000N
+    W1J
+
+  To control the LED display, use the following :
+
+    echo 0x0T000DDD > /sys/devices/platform/asus-laptop/
+
+  where T control the 3 letters display, and DDD the 3 digits display,
+  according to the tables below.
+

+		   - 0x1 should allow to control the device with Fn+Fx key.
+		   - 0x4 should send an ACPI event (0x88) while pressing the Fn+Fx key

+Unsupported models
+------------------

+ These models will never be supported by this module, as they use a completely
+ different mechanism to handle LEDs and extra stuff (meaning we have no clue

+Patches, Errors, Questions:
+--------------------------
+
+ I appreciate any success or failure
+ reports, especially if they add to or correct the compatibility table.
+ Please include the following information in your report:
+
+ - Asus model name
+ - a copy of your ACPI tables, using the "acpidump" utility
+ - a copy of /sys/devices/platform/asus-laptop/infos
+ - which driver features work and which don't
+ - the observed behavior of non-working features

+Regulator API design notes
+==========================
+
+This document provides a brief, partially structured, overview of some
+of the design considerations which impact the regulator API design.
+
+Safety
+------
+
+ - Errors in regulator configuration can have very serious consequences
+   for the system, potentially including lasting hardware damage.
+ - It is not possible to automatically determine the power confugration
+   of the system - software-equivalent variants of the same chip may
+   have different power requirments, and not all components with power
+   requirements are visible to software.
+
+  => The API should make no changes to the hardware state unless it has
+     specific knowledge that these changes are safe to do perform on
+     this particular system.
+
+Consumer use cases
+------------------
+
+ - The overwhelming majority of devices in a system will have no
+   requirement to do any runtime configuration of their power beyond
+   being able to turn it on or off.
+
+ - Many of the power supplies in the system will be shared between many
+   different consumers.
+
+  => The consumer API should be structured so that these use cases are
+     very easy to handle and so that consumers will work with shared
+     supplies without any additional effort.

+================
+HELPER FUNCTIONS
+================
+
+The slow-work facility provides a function by which it can be determined
+whether or not an item is queued for later execution:
+
+	bool queued = slow_work_is_queued(struct slow_work *work);
+
+If it returns false, then the item is not on the queue (it may be executing
+with a requeue pending).  This can be used to work out whether an item on which
+another depends is on the queue, thus allowing a dependent item to be queued
+after it.
+
+If the above shows an item on which another depends not to be queued, then the
+owner of the dependent item might need to wait.  However, to avoid locking up
+the threads unnecessarily be sleeping in them, it can make sense under some
+circumstances to return the work item to the queue, thus deferring it until
+some other items have had a chance to make use of the yielded thread.
+
+To yield a thread and defer an item, the work function should simply enqueue
+the work item again and return.  However, this doesn't work if there's nothing
+actually on the queue, as the thread just vacated will jump straight back into
+the item's work function, thus busy waiting on a CPU.
+
+Instead, the item should use the thread to wait for the dependency to go away,
+but rather than using schedule() or schedule_timeout() to sleep, it should use
+the following function:
+
+	bool requeue = slow_work_sleep_till_thread_needed(
+			struct slow_work *work,
+			signed long *_timeout);
+
+This will add a second wait and then sleep, such that it will be woken up if
+either something appears on the queue that could usefully make use of the
+thread - and behind which this item can be queued, or if the event the caller
+set up to wait for happens.  True will be returned if something else appeared
+on the queue and this work function should perhaps return, of false if
+something else woke it up.  The timeout is as for schedule_timeout().
+
+For example:
+
+	wq = bit_waitqueue(&my_flags, MY_BIT);
+	init_wait(&wait);
+	requeue = false;
+	do {
+		prepare_to_wait(wq, &wait, TASK_UNINTERRUPTIBLE);
+		if (!test_bit(MY_BIT, &my_flags))
+			break;
+		requeue = slow_work_sleep_till_thread_needed(&my_work,
+							     &timeout);
+	} while (timeout > 0 && !requeue);
+	finish_wait(wq, &wait);
+	if (!test_bit(MY_BIT, &my_flags)

+			Subsystem Trace Points: kmem
+
+The tracing system kmem captures events related to object and page allocation
+within the kernel. Broadly speaking there are four major subheadings.
+
+  o Slab allocation of small objects of unknown type (kmalloc)
+  o Slab allocation of small objects of known type
+  o Page allocation
+  o Per-CPU Allocator Activity
+  o External Fragmentation
+
+This document will describe what each of the tracepoints are and why they
+might be useful.
+
+1. Slab allocation of small objects of unknown type
+===================================================
+kmalloc		call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s
+kmalloc_node	call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s node=%d
+kfree		call_site=%lx ptr=%p
+
+Heavy activity for these events may indicate that a specific cache is
+justified, particularly if kmalloc slab pages are getting significantly
+internal fragmented as a result of the allocation pattern. By correlating
+kmalloc with kfree, it may be possible to identify memory leaks and where
+the allocation sites were.
+
+
+2. Slab allocation of small objects of known type
+=================================================
+kmem_cache_alloc	call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s
+kmem_cache_alloc_node	call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s node=%d
+kmem_cache_free		call_site=%lx ptr=%p
+
+These events are similar in usage to the kmalloc-related events except that
+it is likely easier to pin the event down to a specific cache. At the time
+of writing, no information is available on what slab is being allocated from,
+but the call_site can usually be used to extrapolate that information
+
+3. Page allocation
+==================
+mm_page_alloc		  page=%p pfn=%lu order=%d migratetype=%d gfp_flags=%s
+mm_page_alloc_zone_locked page=%p pfn=%lu order=%u migratetype=%d cpu=%d percpu_refill=%d
+mm_page_free_direct	  page=%p pfn=%lu order=%d
+mm_pagevec_free		  page=%p pfn=%lu order=%d cold=%d
+
+These four events deal with page allocation and freeing. mm_page_alloc is
+a simple indicator of page allocator activity. Pages may be allocated from
+the per-CPU allocator (high performance) or the buddy allocator.
+
+If pages are allocated directly from the buddy allocator, the
+mm_page_alloc_zone_locked event is triggered. This event is important as high
+amounts of activity imply high activity on the zone->lock. Taking this lock
+impairs performance by disabling interrupts, dirtying cache lines between
+CPUs and serialising many CPUs.
+
+When a page is freed directly by the caller, the mm_page_free_direct event
+is triggered. Significant amounts of activity here could indicate that the
+callers should be batching their activities.
+
+When pages are freed using a pagevec, the mm_pagevec_free is
+triggered. Broadly speaking, pages are taken off the LRU lock in bulk and
+freed in batch with a pagevec. Significant amounts of activity here could
+indicate that the system is under memory pressure and can also indicate
+contention on the zone->lru_lock.
+
+4. Per-CPU Allocator Activity
+=============================
+mm_page_alloc_zone_locked	page=%p pfn=%lu order=%u migratetype=%d cpu=%d percpu_refill=%d
+mm_page_pcpu_drain		page=%p pfn=%lu order=%d cpu=%d migratetype=%d
+
+In front of the page allocator is a per-cpu page allocator. It exists only
+for order-0 pages, reduces contention on the zone->lock and reduces the
+amount of writing on struct page.
+
+When a per-CPU list is empty or pages of the wrong type are allocated,
+the zone->lock will be taken once and the per-CPU list refilled. The event
+triggered is mm_page_alloc_zone_locked for each page allocated with the
+event indicating whether it is for a percpu_refill or not.
+
+When the per-CPU list is too full, a number of pages are freed, each one
+which triggers a mm_page_pcpu_drain event.
+
+The individual nature of the events are so that pages can be tracked
+between allocation and freeing. A number of drain or refill pages that occur
+consecutively imply the zone->lock being taken once. Large amounts of PCP
+refills and drains could imply an imbalance between CPUs where too much work
+is being concentrated in one place. It could also indicate that the per-CPU
+lists should be a larger size. Finally, large amounts of refills on one CPU
+and drains on another could be a factor in causing large amounts of cache
+line bounces due to writes between CPUs and worth investigating if pages
+can be allocated and freed on the same CPU through some algorithm change.
+
+5. External Fragmentation
+=========================
+mm_page_alloc_extfrag		page=%p pfn=%lu alloc_order=%d fallback_order=%d pageblock_order=%d alloc_migratetype=%d fallback_migratetype=%d fragmenting=%d change_ownership=%d
+
+External fragmentation affects whether a high-order allocation will be
+successful or not. For some types of hardware, this is important although
+it is avoided where possible. If the system is using huge pages and needs
+to be able to resize the pool over the lifetime of the system, this value
+is important.
+
+Large numbers of this event implies that memory is fragmenting and
+high-order allocations will start failing at some time in the future. One
+means of reducing the occurange of this event is to increase the size of
+min_free_kbytes in increments of 3*pageblock_size*nr_online_nodes where
+pageblock_size is usually the size of the default hugepage size.

+		Notes on Analysing Behaviour Using Events and Tracepoints
+
+			Documentation written by Mel Gorman
+		PCL information heavily based on email from Ingo Molnar
+
+1. Introduction
+===============
+
+Tracepoints (see Documentation/trace/tracepoints.txt) can be used without
+creating custom kernel modules to register probe functions using the event
+tracing infrastructure.
+
+Simplistically, tracepoints will represent an important event that when can
+be taken in conjunction with other tracepoints to build a "Big Picture" of
+what is going on within the system. There are a large number of methods for
+gathering and interpreting these events. Lacking any current Best Practises,
+this document describes some of the methods that can be used.
+
+This document assumes that debugfs is mounted on /sys/kernel/debug and that
+the appropriate tracing options have been configured into the kernel. It is
+assumed that the PCL tool tools/perf has been installed and is in your path.
+
+2. Listing Available Events
+===========================
+
+2.1 Standard Utilities
+----------------------
+
+All possible events are visible from /sys/kernel/debug/tracing/events. Simply
+calling
+
+  $ find /sys/kernel/debug/tracing/events -type d
+
+will give a fair indication of the number of events available.
+
+2.2 PCL
+-------
+
+Discovery and enumeration of all counters and events, including tracepoints
+are available with the perf tool. Getting a list of available events is a
+simple case of
+
+  $ perf list 2>&1 | grep Tracepoint
+  ext4:ext4_free_inode                     [Tracepoint event]
+  ext4:ext4_request_inode                  [Tracepoint event]
+  ext4:ext4_allocate_inode                 [Tracepoint event]
+  ext4:ext4_write_begin                    [Tracepoint event]
+  ext4:ext4_ordered_write_end              [Tracepoint event]
+  [ .... remaining output snipped .... ]
+
+
+2. Enabling Events
+==================
+
+2.1 System-Wide Event Enabling
+------------------------------
+
+See Documentation/trace/events.txt for a proper description on how events
+can be enabled system-wide. A short example of enabling all events related
+to page allocation would look something like
+
+  $ for i in `find /sys/kernel/debug/tracing/events -name "enable" | grep mm_`; do echo 1 > $i; done
+
+2.2 System-Wide Event Enabling with SystemTap
+---------------------------------------------
+
+In SystemTap, tracepoints are accessible using the kernel.trace() function
+call. The following is an example that reports every 5 seconds what processes
+were allocating the pages.
+
+  global page_allocs
+
+  probe kernel.trace("mm_page_alloc") {
+  	page_allocs[execname()]++
+  }
+
+  function print_count() {
+  	printf ("%-25s %-s\n", "#Pages Allocated", "Process Name")
+  	foreach (proc in page_allocs-)
+  		printf("%-25d %s\n", page_allocs[proc], proc)
+  	printf ("\n")
+  	delete page_allocs
+  }
+
+  probe timer.s(5) {
+          print_count()
+  }
+
+2.3 System-Wide Event Enabling with PCL
+---------------------------------------
+
+By specifying the -a switch and analysing sleep, the system-wide events
+for a duration of time can be examined.
+
+ $ perf stat -a \
+	-e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+	-e kmem:mm_pagevec_free \
+	sleep 10
+ Performance counter stats for 'sleep 10':
+
+           9630  kmem:mm_page_alloc
+           2143  kmem:mm_page_free_direct
+           7424  kmem:mm_pagevec_free
+
+   10.002577764  seconds time elapsed
+
+Similarly, one could execute a shell and exit it as desired to get a report
+at that point.
+
+2.4 Local Event Enabling
+------------------------
+
+Documentation/trace/ftrace.txt describes how to enable events on a per-thread
+basis using set_ftrace_pid.
+
+2.5 Local Event Enablement with PCL
+-----------------------------------
+
+Events can be activate and tracked for the duration of a process on a local
+basis using PCL such as follows.
+
+  $ perf stat -e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+		 -e kmem:mm_pagevec_free ./hackbench 10
+  Time: 0.909
+
+    Performance counter stats for './hackbench 10':
+
+          17803  kmem:mm_page_alloc
+          12398  kmem:mm_page_free_direct
+           4827  kmem:mm_pagevec_free
+
+    0.973913387  seconds time elapsed
+
+3. Event Filtering
+==================
+
+Documentation/trace/ftrace.txt covers in-depth how to filter events in
+ftrace.  Obviously using grep and awk of trace_pipe is an option as well
+as any script reading trace_pipe.
+
+4. Analysing Event Variances with PCL
+=====================================
+
+Any workload can exhibit variances between runs and it can be important
+to know what the standard deviation in. By and large, this is left to the
+performance analyst to do it by hand. In the event that the discrete event
+occurrences are useful to the performance analyst, then perf can be used.
+
+  $ perf stat --repeat 5 -e kmem:mm_page_alloc -e kmem:mm_page_free_direct
+			-e kmem:mm_pagevec_free ./hackbench 10
+  Time: 0.890
+  Time: 0.895
+  Time: 0.915
+  Time: 1.001
+  Time: 0.899
+
+   Performance counter stats for './hackbench 10' (5 runs):
+
+          16630  kmem:mm_page_alloc         ( +-   3.542% )
+          11486  kmem:mm_page_free_direct   ( +-   4.771% )
+           4730  kmem:mm_pagevec_free       ( +-   2.325% )
+
+    0.982653002  seconds time elapsed   ( +-   1.448% )
+
+In the event that some higher-level event is required that depends on some
+aggregation of discrete events, then a script would need to be developed.
+
+Using --repeat, it is also possible to view how events are fluctuating over
+time on a system wide basis using -a and sleep.
+
+  $ perf stat -e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+		-e kmem:mm_pagevec_free \
+		-a --repeat 10 \
+		sleep 1
+  Performance counter stats for 'sleep 1' (10 runs):
+
+           1066  kmem:mm_page_alloc         ( +-  26.148% )
+            182  kmem:mm_page_free_direct   ( +-   5.464% )
+            890  kmem:mm_pagevec_free       ( +-  30.079% )
+
+    1.002251757  seconds time elapsed   ( +-   0.005% )
+
+5. Higher-Level Analysis with Helper Scripts
+============================================
+
+When events are enabled the events that are triggering can be read from
+/sys/kernel/debug/tracing/trace_pipe in human-readable format although binary
+options exist as well. By post-processing the output, further information can
+be gathered on-line as appropriate. Examples of post-processing might include
+
+  o Reading information from /proc for the PID that triggered the event
+  o Deriving a higher-level event from a series of lower-level events.
+  o Calculate latencies between two events
+
+Documentation/trace/postprocess/trace-pagealloc-postprocess.pl is an example
+script that can read trace_pipe from STDIN or a copy of a trace. When used
+on-line, it can be interrupted once to generate a report without existing
+and twice to exit.
+
+Simplistically, the script just reads STDIN and counts up events but it
+also can do more such as
+
+  o Derive high-level events from many low-level events. If a number of pages
+    are freed to the main allocator from the per-CPU lists, it recognises
+    that as one per-CPU drain even though there is no specific tracepoint
+    for that event
+  o It can aggregate based on PID or individual process number
+  o In the event memory is getting externally fragmented, it reports
+    on whether the fragmentation event was severe or moderate.
+  o When receiving an event about a PID, it can record who the parent was so
+    that if large numbers of events are coming from very short-lived
+    processes, the parent process responsible for creating all the helpers
+    can be identified
+
+6. Lower-Level Analysis with PCL
+================================
+
+There may also be a requirement to identify what functions with a program
+were generating events within the kernel. To begin this sort of analysis, the
+data must be recorded. At the time of writing, this required root
+
+  $ perf record -c 1 \
+	-e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+	-e kmem:mm_pagevec_free \
+	./hackbench 10
+  Time: 0.894
+  [ perf record: Captured and wrote 0.733 MB perf.data (~32010 samples) ]
+
+Note the use of '-c 1' to set the event period to sample. The default sample
+period is quite high to minimise overhead but the information collected can be
+very coarse as a result.
+
+This record outputted a file called perf.data which can be analysed using
+perf report.
+
+  $ perf report
+  # Samples: 30922
+  #
+  # Overhead    Command                     Shared Object
+  # ........  .........  ................................
+  #
+      87.27%  hackbench  [vdso]
+       6.85%  hackbench  /lib/i686/cmov/libc-2.9.so
+       2.62%  hackbench  /lib/ld-2.9.so
+       1.52%       perf  [vdso]
+       1.22%  hackbench  ./hackbench
+       0.48%  hackbench  [kernel]

+  #
+  # (For more details, try: perf report --sort comm,dso,symbol)
+  #
+
+According to this, the vast majority of events occured triggered on events
+within the VDSO. With simple binaries, this will often be the case so lets
+take a slightly different example. In the course of writing this, it was
+noticed that X was generating an insane amount of page allocations so lets look
+at it
+
+  $ perf record -c 1 -f \
+		-e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+		-e kmem:mm_pagevec_free \
+		-p `pidof X`
+
+This was interrupted after a few seconds and
+

+At a glance, it looks like the time is being spent copying pixmaps to
+the card.  Further investigation would be needed to determine why pixmaps
+are being copied around so much but a starting point would be to take an
+ancient build of libpixmap out of the library path where it was totally
+forgotten about from months ago!

+What is hwpoison?
+
+Upcoming Intel CPUs have support for recovering from some memory errors
+(``MCA recovery''). This requires the OS to declare a page "poisoned",
+kill the processes associated with it and avoid using it in the future.
+
+This patchkit implements the necessary infrastructure in the VM.
+
+To quote the overview comment:
+
+ * High level machine check handler. Handles pages reported by the
+ * hardware as being corrupted usually due to a 2bit ECC memory or cache
+ * failure.
+ *
+ * This focusses on pages detected as corrupted in the background.
+ * When the current CPU tries to consume corruption the currently
+ * running process can just be killed directly instead. This implies
+ * that if the error cannot be handled for some reason it's safe to
+ * just ignore it because no corruption has been consumed yet. Instead
+ * when that happens another machine check will happen.
+ *
+ * Handles page cache pages in various states. The tricky part
+ * here is that we can access any page asynchronous to other VM
+ * users, because memory failures could happen anytime and anywhere,
+ * possibly violating some of their assumptions. This is why this code
+ * has to be extremely careful. Generally it tries to use normal locking
+ * rules, as in get the standard locks, even if that means the
+ * error handling takes potentially a long time.
+ *
+ * Some of the operations here are somewhat inefficient and have non
+ * linear algorithmic complexity, because the data structures have not
+ * been optimized for this case. This is in particular the case
+ * for the mapping from a vma to a process. Since this case is expected
+ * to be rare we hope we can get away with this.
+
+The code consists of a the high level handler in mm/memory-failure.c,
+a new page poison bit and various checks in the VM to handle poisoned
+pages.
+
+The main target right now is KVM guests, but it works for all kinds
+of applications. KVM support requires a recent qemu-kvm release.
+
+For the KVM use there was need for a new signal type so that
+KVM can inject the machine check into the guest with the proper
+address. This in theory allows other applications to handle
+memory failures too. The expection is that near all applications
+won't do that, but some very specialized ones might.
+
+---
+
+There are two (actually three) modi memory failure recovery can be in:
+
+vm.memory_failure_recovery sysctl set to zero:
+	All memory failures cause a panic. Do not attempt recovery.
+	(on x86 this can be also affected by the tolerant level of the
+	MCE subsystem)
+
+early kill
+	(can be controlled globally and per process)
+	Send SIGBUS to the application as soon as the error is detected
+	This allows applications who can process memory errors in a gentle
+	way (e.g. drop affected object)
+	This is the mode used by KVM qemu.
+
+late kill
+	Send SIGBUS when the application runs into the corrupted page.
+	This is best for memory error unaware applications and default
+	Note some pages are always handled as late kill.
+
+---
+
+User control:
+
+vm.memory_failure_recovery
+	See sysctl.txt
+
+vm.memory_failure_early_kill
+	Enable early kill mode globally
+
+PR_MCE_KILL
+	Set early/late kill mode/revert to system default

+How to use the Kernel Samepage Merging feature
+----------------------------------------------
+
+KSM is a memory-saving de-duplication feature, enabled by CONFIG_KSM=y,
+added to the Linux kernel in 2.6.32.  See mm/ksm.c for its implementation,
+and http://lwn.net/Articles/306704/ and http://lwn.net/Articles/330589/
+
+The KSM daemon ksmd periodically scans those areas of user memory which
+have been registered with it, looking for pages of identical content which
+can be replaced by a single write-protected page (which is automatically
+copied if a process later wants to update its content).
+
+KSM was originally developed for use with KVM (where it was known as
+Kernel Shared Memory), to fit more virtual machines into physical memory,
+by sharing the data common between them.  But it can be useful to any
+application which generates many instances of the same data.
+
+KSM only merges anonymous (private) pages, never pagecache (file) pages.
+KSM's merged pages are at present locked into kernel memory for as long
+as they are shared: so cannot be swapped out like the user pages they
+replace (but swapping KSM pages should follow soon in a later release).
+
+KSM only operates on those areas of address space which an application
+has advised to be likely candidates for merging, by using the madvise(2)
+system call: int madvise(addr, length, MADV_MERGEABLE).
+
+The app may call int madvise(addr, length, MADV_UNMERGEABLE) to cancel
+that advice and restore unshared pages: whereupon KSM unmerges whatever
+it merged in that range.  Note: this unmerging call may suddenly require
+more memory than is available - possibly failing with EAGAIN, but more
+probably arousing the Out-Of-Memory killer.
+
+If KSM is not configured into the running kernel, madvise MADV_MERGEABLE
+and MADV_UNMERGEABLE simply fail with EINVAL.  If the running kernel was
+built with CONFIG_KSM=y, those calls will normally succeed: even if the
+the KSM daemon is not currently running, MADV_MERGEABLE still registers
+the range for whenever the KSM daemon is started; even if the range
+cannot contain any pages which KSM could actually merge; even if
+MADV_UNMERGEABLE is applied to a range which was never MADV_MERGEABLE.
+
+Like other madvise calls, they are intended for use on mapped areas of
+the user address space: they will report ENOMEM if the specified range
+includes unmapped gaps (though working on the intervening mapped areas),
+and might fail with EAGAIN if not enough memory for internal structures.
+
+Applications should be considerate in their use of MADV_MERGEABLE,
+restricting its use to areas likely to benefit.  KSM's scans may use
+a lot of processing power, and its kernel-resident pages are a limited
+resource.  Some installations will disable KSM for these reasons.
+
+The KSM daemon is controlled by sysfs files in /sys/kernel/mm/ksm/,
+readable by all but writable only by root:
+
+max_kernel_pages - set to maximum number of kernel pages that KSM may use
+                   e.g. "echo 100000 > /sys/kernel/mm/ksm/max_kernel_pages"
+                   Value 0 imposes no limit on the kernel pages KSM may use;
+                   but note that any process using MADV_MERGEABLE can cause
+                   KSM to allocate these pages, unswappable until it exits.
+                   Default: quarter of memory (chosen to not pin too much)
+
+pages_to_scan    - how many present pages to scan before ksmd goes to sleep
+                   e.g. "echo 100 > /sys/kernel/mm/ksm/pages_to_scan"
+                   Default: 100 (chosen for demonstration purposes)
+
+sleep_millisecs  - how many milliseconds ksmd should sleep before next scan
+                   e.g. "echo 20 > /sys/kernel/mm/ksm/sleep_millisecs"
+                   Default: 20 (chosen for demonstration purposes)
+
+run              - set 0 to stop ksmd from running but keep merged pages,
+                   set 1 to run ksmd e.g. "echo 1 > /sys/kernel/mm/ksm/run",
+                   set 2 to stop ksmd and unmerge all pages currently merged,
+                         but leave mergeable areas registered for next run
+                   Default: 0 (must be changed to 1 to activate KSM,
+                               except if CONFIG_SYSFS is disabled)
+
+The effectiveness of KSM and MADV_MERGEABLE is shown in /sys/kernel/mm/ksm/:
+
+pages_shared     - how many shared unswappable kernel pages KSM is using
+pages_sharing    - how many more sites are sharing them i.e. how much saved
+pages_unshared   - how many pages unique but repeatedly checked for merging
+pages_volatile   - how many pages changing too fast to be placed in a tree
+full_scans       - how many times all mergeable areas have been scanned
+
+A high ratio of pages_sharing to pages_shared indicates good sharing, but
+a high ratio of pages_unshared to pages_sharing indicates wasted effort.
+pages_volatile embraces several different kinds of activity, but a high
+proportion there would also indicate poor use of madvise MADV_MERGEABLE.

-	 * - do not use stacked registers, the caller owns them.
-	 * - do not use the scratch stack space, the caller owns it.
-	 * - do not use any registers other than the ones listed below
-	 *
-	 * Inputs:
-	 *   ar.pfs - saved CFM of caller
-	 *   ar.ccv - 0 (and available for use)
-	 *   r27    - flags from spin_lock_irqsave or 0.  Must be preserved.

 /* hardirq.h: PA-RISC hard IRQ support.

  * Copyright (C) 2001 Matthew Wilcox <matthew@wil.cx>
- *
- * The locking is really quite interesting.  There's a cpu-local
- * count of how many interrupts are being handled, and a global
- * lock.  An interrupt can only be serviced if the global lock
- * is free.  You can't be sure no more interrupts are being
- * serviced until you've acquired the lock and then checked
- * all the per-cpu interrupt counts are all zero.  It's a specialised
- * br_lock, and that's exactly how Sparc does it.  We don't because
- * it's more locking for us.  This way is lock-free in the interrupt path.

-/* Sparc64 chips have two performance counters, 32-bits each, with

- * The counters are accessed in one go using a 64-bit register.
- *
- * Both counters are controlled using a single control register.  The
- * only way to stop all sampling is to clear all of the context (user,
- * supervisor, hypervisor) sampling enable bits.  But these bits apply
- * to both counters, thus the two counters can't be enabled/disabled
- * individually.
- *
- * The control register has two event fields, one for each of the two
- * counters.  It's thus nearly impossible to have one counter going
- * while keeping the other one stopped.  Therefore it is possible to
- * get overflow interrupts for counters not currently "in use" and
- * that condition must be checked in the overflow interrupt handler.
- *
- * So we use a hack, in that we program inactive counters with the
- * "sw_count0" and "sw_count1" events.  These count how many times
- * the instruction "sethi %hi(0xfc000), %g0" is executed.  It's an
- * unusual way to encode a NOP and therefore will not trigger in

+/* Sparc64 chips have two performance counters, 32-bits each, with
+ * overflow interrupts generated on transition from 0xffffffff to 0.
+ * The counters are accessed in one go using a 64-bit register.
+ *
+ * Both counters are controlled using a single control register.  The
+ * only way to stop all sampling is to clear all of the context (user,
+ * supervisor, hypervisor) sampling enable bits.  But these bits apply
+ * to both counters, thus the two counters can't be enabled/disabled
+ * individually.
+ *
+ * The control register has two event fields, one for each of the two
+ * counters.  It's thus nearly impossible to have one counter going
+ * while keeping the other one stopped.  Therefore it is possible to
+ * get overflow interrupts for counters not currently "in use" and
+ * that condition must be checked in the overflow interrupt handler.
+ *
+ * So we use a hack, in that we program inactive counters with the
+ * "sw_count0" and "sw_count1" events.  These count how many times
+ * the instruction "sethi %hi(0xfc000), %g0" is executed.  It's an
+ * unusual way to encode a NOP and therefore will not trigger in
+ * normal code.

+ * Concepts and ideas behind the menu governor
+ *
+ * For the menu governor, there are 3 decision factors for picking a C
+ * state:
+ * 1) Energy break even point
+ * 2) Performance impact
+ * 3) Latency tolerance (from pmqos infrastructure)
+ * These these three factors are treated independently.
+ *
+ * Energy break even point
+ * -----------------------
+ * C state entry and exit have an energy cost, and a certain amount of time in
+ * the  C state is required to actually break even on this cost. CPUIDLE
+ * provides us this duration in the "target_residency" field. So all that we
+ * need is a good prediction of how long we'll be idle. Like the traditional
+ * menu governor, we start with the actual known "next timer event" time.
+ *
+ * Since there are other source of wakeups (interrupts for example) than
+ * the next timer event, this estimation is rather optimistic. To get a
+ * more realistic estimate, a correction factor is applied to the estimate,
+ * that is based on historic behavior. For example, if in the past the actual
+ * duration always was 50% of the next timer tick, the correction factor will
+ * be 0.5.
+ *
+ * menu uses a running average for this correction factor, however it uses a
+ * set of factors, not just a single factor. This stems from the realization
+ * that the ratio is dependent on the order of magnitude of the expected
+ * duration; if we expect 500 milliseconds of idle time the likelihood of
+ * getting an interrupt very early is much higher than if we expect 50 micro
+ * seconds of idle time. A second independent factor that has big impact on
+ * the actual factor is if there is (disk) IO outstanding or not.
+ * (as a special twist, we consider every sleep longer than 50 milliseconds
+ * as perfect; there are no power gains for sleeping longer than this)
+ *
+ * For these two reasons we keep an array of 12 independent factors, that gets
+ * indexed based on the magnitude of the expected duration as well as the
+ * "is IO outstanding" property.
+ *
+ * Limiting Performance Impact
+ * ---------------------------
+ * C states, especially those with large exit latencies, can have a real
+ * noticable impact on workloads, which is not acceptable for most sysadmins,
+ * and in addition, less performance has a power price of its own.
+ *
+ * As a general rule of thumb, menu assumes that the following heuristic
+ * holds:
+ *     The busier the system, the less impact of C states is acceptable
+ *
+ * This rule-of-thumb is implemented using a performance-multiplier:
+ * If the exit latency times the performance multiplier is longer than
+ * the predicted duration, the C state is not considered a candidate
+ * for selection due to a too high performance impact. So the higher
+ * this multiplier is, the longer we need to be idle to pick a deep C
+ * state, and thus the less likely a busy CPU will hit such a deep
+ * C state.
+ *
+ * Two factors are used in determing this multiplier:
+ * a value of 10 is added for each point of "per cpu load average" we have.
+ * a value of 5 points is added for each process that is waiting for
+ * IO on this CPU.
+ * (these values are experimentally determined)
+ *
+ * The load average factor gives a longer term (few seconds) input to the
+ * decision, while the iowait value gives a cpu local instantanious input.
+ * The iowait factor may look low, but realize that this is also already
+ * represented in the system load average.

-
-* The PCF8574 is an 8-bit I/O expander for the I2C bus produced by

-  interface to up to 8 separate devices.
-  
-* The PCF8574 appears as a very simple SMBus device which can be

+ * Like it or not, but the chip always saves a received CAN message
+ * into the first free mailbox it finds (starting with the
+ * lowest). This makes it very difficult to read the messages in the
+ * right order from the chip. This is how we work around that problem:
+ *
+ * The first message goes into mb nr. 0 and issues an interrupt. All
+ * rx ints are disabled in the interrupt handler and a napi poll is
+ * scheduled. We read the mailbox, but do _not_ reenable the mb (to
+ * receive another message).
+ *

+ *
+ * The variable priv->rx_next points to the next mailbox to read a
+ * message from. As long we're in the lower mailboxes we just read the
+ * mailbox but not reenable it.
+ *
+ * With completion of the last of the lower mailboxes, we reenable the
+ * whole first group, but continue to look for filled mailboxes in the
+ * upper mailboxes. Imagine the second group like overflow mailboxes,
+ * which takes CAN messages if the lower goup is full. While in the
+ * upper group we reenable the mailbox right after reading it. Giving

+ *
+ * 	BFI_IOIM_STS_HOST_ABORTED	: IO was aborted successfully due to

+ * 					   - io-tag cannot be reused yet.
+ *
+ * 	BFI_IOIM_STS_ABORTED		: IO was aborted successfully
+ *					   internally by f/w.
+ * 					   - io-tag cannot be reused yet.
+ *
+ * 	BFI_IOIM_STS_TIMEDOUT	: IO timedout and ABTS/RRQ is happening
+ *					   in the firmware and
+ * 					   - io-tag cannot be reused yet.
+ *
+ * 	BFI_IOIM_STS_SQER_NEEDED	: Firmware could not recover the IO
+ *					  with sequence level error
+ * 					  logic and hence host needs to retry
+ *					  this IO with a different IO tag
+ * 					  - io-tag cannot be used yet.
+ *
+ * 	BFI_IOIM_STS_NEXUS_ABORT	: Second Level Error Recovery from host
+ *					  is required because 2 consecutive ABTS
+ *					  timedout and host needs logout and
+ *					  re-login with the target
+ * 					  - io-tag cannot be used yet.
+ *
+ * 	BFI_IOIM_STS_UNDERRUN	: IO completed with SCSI status good,
+ *					  but the data tranferred is less than
+ *					  the fcp data length in the command.
+ *					  ex. SCSI INQUIRY where transferred
+ *					  data length and residue count in FCP

+ *					  TAPE IOs where blocks can of unequal
+ *					  lengths.
+ * 					  - io-tag can be reused.
+ *
+ * 	BFI_IOIM_STS_RES_FREE	: Firmware has completed using io-tag
+ *					  during abort process
+ * 					  - io-tag can be reused.
+ *
+ * 	BFI_IOIM_STS_PROTO_ERR	: Firmware detected a protocol error.
+ *					  ex target sent more data than
+ *					  requested, or there was data frame
+ *					  loss and other reasons
+ * 					  - io-tag cannot be used yet.
+ *
+ * 	BFI_IOIM_STS_DIF_ERR	: Firwmare detected DIF error. ex: DIF
+ * 					  CRC err or Ref Tag err or App tag err.
+ * 					  - io-tag can be reused.
+ *
+ * 	BFA_IOIM_STS_TSK_MGT_ABORT	: IO was aborted because of Task

+ * 					  - io-tag can be reused.

+	---help---
+	The Simple Firmware Interface (SFI) provides a lightweight method
+	for platform firmware to pass information to the operating system
+	via static tables in memory.  Kernel SFI support is required to
+	boot on SFI-only platforms.  Currently, all SFI-only platforms are
+	based on the 2nd generation Intel Atom processor platform,
+	code-named Moorestown.
+
+	For more information, see http://simplefirmware.org
+
+	Say 'Y' here to enable the kernel to boot on SFI-only platforms.

-1: The RX get too much "CRC failed" pakets, it make the card work very unstable,
-2: After running a while, the card will get infinity "RX Frame" and "Error"
-interrupt, not know the root reason so far, try to fix it
-3: Using two tx queue txd and txm but not only txm.
-4: Set the hdr correctly.
-5: Try to do recalibrate correvtly
-6: To support G mode in future
-7: Fix the mac address can't be readed and set correctly in BE machine.
-8: Fix include and exclude FCS in promisous mode and manage mode
-9: Using sta_notify to notice sta change
-10: Turn on frame reception at the end of start
-11: Guess the card support HW_MULTICAST_FILTER
-12: The tx process should be implment atomic?
-13: Using mac80211 function to control the TX&RX LED.

-	  Cowloop is a "copy-on-write" pseudo block driver. It can be
-	  stacked on top of a "real" block driver, and catches all write
-	  operations on their way from the file systems layer above to
-	  the real driver below, effectively shielding the lower driver
-	  from those write accesses. The requests are then diverted to
-	  an ordinary file, located somewhere else (configurable). Later
-	  read requests are checked to see whether they can be serviced
-	  by the "real" block driver below, or must be pulled in from
-	  the diverted location. More information and userspace tools to
-	  use the driver are on the project's website

-**       COWLOOP block device driver (2.6 kernel compliant)
-** =======================================================================
-** Read-write loop-driver with copy-on-write functionality.
-**
-** Synopsis:
-**
-**     modprobe cowloop [maxcows=..] [rdofile=..... cowfile=.... [option=r]]
-**
-** Definition of number of configured cowdevices:
-**   maxcows=	number of configured cowdevices (default: 16)
-** (do not confuse this with MAXCOWS: absolute maximum as compiled)
-**
-** One pair of filenames can be supplied during insmod/modprobe to open
-** the first cowdevice:
-**   rdofile=	read-only file (or filesystem)
-**   cowfile=	storage-space for modified blocks of read-only file(system)
-**   option=r	repair cowfile automatically if it appears to be dirty
-**
-** Other cowdevices can be activated via the command "cowdev"
-** whenever the cowloop-driver is loaded.
-**
-** The read-only file may be of type 'regular' or 'block-device'.
-**
-** The cowfile must be of type 'regular'.
-** If an existing regular file is used as cowfile, its contents will be
-** used again for the current read-only file. When the cowfile has not been
-** closed properly during a previous session (i.e. rmmod cowloop), the
-** cowloop-driver refuses to open it unless the parameter "option=r" is
-** specified.
-**
-** Layout of cowfile:

-**	200502	Support devices/file > 2 Gbytes.	Gerlof Langeveld
-**	200507	Check for free space to expand cowfile.	Gerlof Langeveld
-**	200902  Upgrade for kernel 2.6.28               Hendrik-Jan Thomassen
-**
-** Inspired by
-**    loop.c  by Theodore Ts'o and
-**    cloop.c by Paul `Rusty' Russell & Klaus Knopper.
-**
-** Design-considerations:
-**
-**   For the first experiments with the cowloop-driver, the request-queue
-**   made use of the do_generic_file_read() which worked fine except
-**   in combination with the cloop-driver; that combination
-**   resulted in a non-interruptible hangup of the system during
-**   heavy load. Other experiments using the `make_request' interface also
-**   resulted in unpredictable system hangups (with proper use of spinlocks).
-**
-**   To overcome these problems, the cowloop-driver starts a kernel-thread
-**   for every active cowdevice.
-**   All read- and write-request on the read-only file and copy-on-write file
-**   are handled in the context of that thread.
-**   A scheme has been designed to wakeup the kernel-thread as
-**   soon as I/O-requests are available in the request-queue; this thread
-**   handles the requests one-by-one by calling the proper read- or
-**   write-function related to the open read-only file or copy-on-write file.
-**   When all pending requests have been handled, the kernel-thread goes
-**   back to sleep-state.
-**   This approach requires some additional context-switches; however the
-**   performance loss during heavy I/O is less than 3%.

+ * accesses to the address and data register.
+ * The following timing options exist:
+ *
+ * 1. Configure your memory controller to add such delays if it can (the best)
+ * 2. Implement platform-specific delay function possibly
+ *    combined with configuring the memory controller; see
+ *    include/linux/usb_isp1362.h for more info.
+ * 3. Use ndelay (easiest, poorest).
+ *
+ * Use the corresponding macros USE_PLATFORM_DELAY and USE_NDELAY in the
+ * platform specific section of isp1362.h to select the appropriate variant.
+ *
+ * Also note that according to the Philips "ISP1362 Errata" document
+ * Rev 1.00 from 27 May data corruption may occur when the #WR signal
+ * is reasserted (even with #CS deasserted) within 132ns after a
+ * write cycle to any controller register. If the hardware doesn't
+ * implement the recommended fix (gating the #WR with #CS) software
+ * must ensure that no further write cycle (not necessarily to the chip!)
+ * is issued by the CPU within this interval.
+
+ * For PXA25x this can be ensured by using VLIO with the maximum
+ * recovery time (MSCx = 0x7f8c) with a memory clock of 99.53 MHz.

+Version 1.61
+------------
+Fix append problem to Samba servers (files opened with O_APPEND could
+have duplicated data). Fix oops in cifs_lookup. Workaround problem
+mounting to OS/400 Netserve. Fix oops in cifs_get_tcp_session.
+Disable use of server inode numbers when server only
+partially supports them (e.g. for one server querying inode numbers on
+FindFirst fails but QPathInfo queries works).
+
 Version 1.60
 -------------
 Fix memory leak in reconnect.  Fix oops in DFS mount error path.

- *       If NR_CPUS is <= 64 then most assembler bitmask

- *    loops buried in the disk_stat_read() macros calls when compiling
- *    drivers/block/genhd.c (arch i386, CONFIG_SMP=y).  So use a simple
- *    one-line #define for cpu_isset(), instead of wrapping an inline
- *    inside a macro, the way we do the other calls.

+ * A few notes about the KSM scanning process,
+ * to make it easier to understand the data structures below:
+ *
+ * In order to reduce excessive scanning, KSM sorts the memory pages by their
+ * contents into a data structure that holds pointers to the pages' locations.
+ *
+ * Since the contents of the pages may change at any moment, KSM cannot just
+ * insert the pages into a normal sorted tree and expect it to find anything.
+ * Therefore KSM uses two data structures - the stable and the unstable tree.
+ *
+ * The stable tree holds pointers to all the merged pages (ksm pages), sorted
+ * by their contents.  Because each such page is write-protected, searching on
+ * this tree is fully assured to be working (except when pages are unmapped),
+ * and therefore this tree is called the stable tree.
+ *
+ * In addition to the stable tree, KSM uses a second data structure called the
+ * unstable tree: this tree holds pointers to pages which have been found to
+ * be "unchanged for a period of time".  The unstable tree sorts these pages
+ * by their contents, but since they are not write-protected, KSM cannot rely
+ * upon the unstable tree to work correctly - the unstable tree is liable to

+ *
+ * KSM solves this problem by several techniques:
+ *
+ * 1) The unstable tree is flushed every time KSM completes scanning all
+ *    memory areas, and then the tree is rebuilt again from the beginning.
+ * 2) KSM will only insert into the unstable tree, pages whose hash value
+ *    has not changed since the previous scan of all memory areas.
+ * 3) The unstable tree is a RedBlack Tree - so its balancing is based on the
+ *    colors of the nodes and not on their contents, assuring that even when
+ *    the tree gets "corrupted" it won't get out of balance, so scanning time
+ *    remains the same (also, searching and inserting nodes in an rbtree uses
+ *    the same algorithm, so we have no overhead when we flush and rebuild).
+ * 4) KSM never flushes the stable tree, which means that even if it were to
+ *    take 10 attempts to find a page in the unstable tree, once it is found,
+ *    it is secured in the stable tree.  (When we scan a new page, we first
+ *    compare it against the stable tree, and then against the unstable tree.)
