+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 exists totally outside the MMU and will
+override any MMU mappings.
+
+Code executing inside the ITCM does not "see" any MMU mappings
+and e.g. register accesses must be made to physical addresses.
+
+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;

+2.3 Mounting hierarchies by name
+--------------------------------
+
+Passing the name=<x> option when mounting a cgroups hierarchy
+associates the given name with the hierarchy. This can be used when
+mounting a pre-existing hierarchy, in order to refer to it by name
+rather than by its set of active subsystems. Each hierarchy is either
+nameless, or has a unique name.
+
+The name should match [\w.-]+
+
+When passing a name=<x> option for a new hierarchy, you need to
+specify subsystems manually; the legacy behaviour of mounting all
+subsystems when none are explicitly specified is not supported when
+you give a subsystem a name.
+
+The name of the subsystem appears as part of the hierarchy description
+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.

+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.

-Kernel driver fscher
-====================
-
-Supported chips:
- * Fujitsu-Siemens Hermes chip
- Prefix: 'fscher'
- Addresses scanned: I2C 0x73
-
-Authors:
- Reinhard Nissl <rnissl@gmx.de> based on work
- from Hermann Jung <hej@odn.de>,

-
-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.

-
-Author: Ben Gardner <bgardner@wabtec.com>
-
-
-Description
------------
-
-The Philips PCA9539 is a 16 bit low power I/O device.
-All 16 lines can be individually configured as an input or output.
-The input sense can also be inverted.
-The 16 lines are split between two bytes.
-
-
-Detection
----------
-
-The PCA9539 is difficult to detect and not commonly found in PC machines,
-so you have to pass the I2C bus and address of the installed PCA9539
-devices explicitly to the driver at load time via the force=... parameter.
-
-
-Sysfs entries
--------------
-
-Each is a byte that maps to the 8 I/O bits.
-A '0' suffix is for bits 0-7, while '1' is for bits 8-15.
-
-input[01] - read the current value
-output[01] - sets the output value
-direction[01] - direction of each bit: 1=input, 0=output
-invert[01] - toggle the input bit sense
-
-input reads the actual state of the line and is always available.
-The direction defaults to input for all channels.
-
-
-General Remarks
----------------
-
-Note that each output, direction, and invert entry controls 8 lines.
-You should use the read, modify, write sequence.
-For example. to set output bit 0 of 1.
- val=$(cat output0)
- val=$(( $val | 1 ))
- echo $val > output0

-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:
-
- * SFE Breakout Board for PCF8575 I2C Expander by RobotShop
- http://www.robotshop.ca/home/products/robot-parts/electronics/adapters-converters/sfe-pcf8575-i2c-expander-board.html
-
- * Breakout Board for PCF8575 I2C Expander by Spark Fun Electronics
- http://www.sparkfun.com/commerce/product_info.php?products_id=8130
-
-
-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:
+
+ +-------+-----+-----+-----+-----+-----+
+ | Bin | Val | DVI | TV | CRT | LCD |
+ +-------+-----+-----+-----+-----+-----+
+ + 0000 + 0 + + + + +
+ +-------+-----+-----+-----+-----+-----+
+ + 0001 + 1 + + + + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 0010 + 2 + + + X + +
+ +-------+-----+-----+-----+-----+-----+
+ + 0011 + 3 + + + X + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 0100 + 4 + + X + + +
+ +-------+-----+-----+-----+-----+-----+
+ + 0101 + 5 + + X + + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 0110 + 6 + + X + X + +
+ +-------+-----+-----+-----+-----+-----+
+ + 0111 + 7 + + X + X + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 1000 + 8 + X + + + +
+ +-------+-----+-----+-----+-----+-----+
+ + 1001 + 9 + X + + + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 1010 + 10 + X + + X + +
+ +-------+-----+-----+-----+-----+-----+
+ + 1011 + 11 + X + + X + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 1100 + 12 + X + X + + +
+ +-------+-----+-----+-----+-----+-----+
+ + 1101 + 13 + X + X + + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 1110 + 14 + X + X + X + +
+ +-------+-----+-----+-----+-----+-----+
+ + 1111 + 15 + X + X + X + X +
+ +-------+-----+-----+-----+-----+-----+
+
+ 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.
+
+ DDD (digits)
+ 000 to 999 = display digits
+ AAA = ---
+ BBB to FFF = turn-off
+
+ T (type)
+ 0 = off
+ 1 = dvd
+ 2 = vcd
+ 3 = mp3
+ 4 = cd
+ 5 = tv
+ 6 = cpu
+ 7 = vol
+
+ For example "echo 0x01000001 >/sys/devices/platform/asus-laptop/ledd"
+ would display "DVD001".
+
+Driver options:
+---------------
+
+ Options can be passed to the asus-laptop driver using the standard
+ module argument syntax (<param>=<value> when passing the option to the
+ module or asus-laptop.<param>=<value> on the kernel boot line when
+ asus-laptop is statically linked into the kernel).
+
+ wapf: WAPF defines the behavior of the Fn+Fx wlan key
+ The significance of values is yet to be found, but
+ most of the time:
+ - 0x0 should do nothing
+ - 0x1 should allow to control the device with Fn+Fx key.
+ - 0x4 should send an ACPI event (0x88) while pressing the Fn+Fx key
+ - 0x5 like 0x1 or 0x4
+
+ The default value is 0x1.
+
+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
+ how it works):
+
+ - ASUS A1300 (A1B), A1370D
+ - ASUS L7300G
+ - ASUS L8400
+
+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
+
+ Any other comments or patches are also more than welcome.

+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.

+core_pipe_limit:
+
+This sysctl is only applicable when core_pattern is configured to pipe core
+files to user space helper a (when the first character of core_pattern is a '|',
+see above). When collecting cores via a pipe to an application, it is
+occasionally usefull for the collecting application to gather data about the
+crashing process from its /proc/pid directory. In order to do this safely, the
+kernel must wait for the collecting process to exit, so as not to remove the
+crashing processes proc files prematurely. This in turn creates the possibility
+that a misbehaving userspace collecting process can block the reaping of a
+crashed process simply by never exiting. This sysctl defends against that. It
+defines how many concurrent crashing processes may be piped to user space
+applications in parallel. If this value is exceeded, then those crashing
+processes above that value are noted via the kernel log and their cores are
+skipped. 0 is a special value, indicating that unlimited processes may be
+captured in parallel, but that no waiting will take place (i.e. the collecting

+Control how to kill processes when uncorrected memory error (typically

-/* A few notes about the PCF8574:
-
-* The PCF8574 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 8 separate devices.
-
-* The PCF8574 appears as a very simple SMBus device which can be
- read from or written to with SMBUS byte read/write accesses.

+ 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.

+ * The completion callback is invoked in a context which can't sleep.

+ * When the callback is issued, message->status holds either zero (to
+ * indicate complete success) or a negative error code. After that
+ * callback returns, the driver which issued the transfer request may
+ * deallocate the associated memory; it's no longer in use by any SPI
+ * core or controller driver code.
+ *
+ * Note that although all messages to a spi_device are handled in
+ * FIFO order, messages may go to different devices in other orders.
+ * Some device might be higher priority, or have various "hard" access
+ * time requirements, for example.
+ *
+ * On detection of any fault during the transfer, processing of
+ * the entire message is aborted, and the device is deselected.
+ * Until returning from the associated message completion callback,
+ * no other spi_message queued to that device will be processed.
+ * (This rule applies equally to all the synchronous transfer calls,

+ CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM
+ and therefore can be supported by more hardware. Technically ECM and
+ EEM are designed for different applications. The ECM model extends
+ the network interface to the target (e.g. a USB cable modem), and the
+ EEM model is for mobile devices to communicate with hosts using
+ ethernet over USB. For Linux gadgets, however, the interface with
+ the host is the same (a usbX device), so the differences are minimal.
+
+ If you say "y" here, the Ethernet gadget driver will use the EEM
+ protocol rather than ECM. If unsure, say "n".

+ * The ISP1362 chip requires a large delay (300ns and 462ns) between
+ * 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.

- Say Y here if you have more than one (supported) Matrox device in
- your computer and you want to use all of them for different monitors
- ("multihead"). If you have only one device, you should say N because
- the driver compiled with Y is larger and a bit slower, especially on
- ia32 (ix86).
-
- If you said M to "Matrox unified accelerated driver" and N here, you
- will still be able to use several Matrox devices simultaneously:
- insert several instances of the module matroxfb into the kernel
- with insmod, supplying the parameter "dev=N" where N is 0, 1, etc.
- for the different Matrox devices. This method is slightly faster but
- uses 40 KB of kernel memory per Matrox card.
-
- There is no need for enabling 'Matrox multihead support' if you have
- only one Matrox card in the box.

Say Y if you intend to mount QNX hard disks or floppies.
- Unless you say Y to "QNX4FS read-write support" below, you will

To compile this file system support as a module, choose M here: the

/*
* Cpumasks provide a bitmap suitable for representing the

- *
- * The new cpumask_ ops take a "struct cpumask *"; the old ones
- * use cpumask_t.
- *
- * See detailed comments in the file linux/bitmap.h describing the
- * data type on which these cpumasks are based.
- *
- * For details of cpumask_scnprintf() and cpumask_parse_user(),

- * For details of cpu_remap(), see bitmap_bitremap in lib/bitmap.c
- * For details of cpus_remap(), see bitmap_remap in lib/bitmap.c.

- *
- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- * Note: The alternate operations with the suffix "_nr" are used
- * to limit the range of the loop to nr_cpu_ids instead of
- * NR_CPUS when NR_CPUS > 64 for performance reasons.
- * If NR_CPUS is <= 64 then most assembler bitmask
- * operators execute faster with a constant range, so
- * the operator will continue to use NR_CPUS.
- *
- * Another consideration is that nr_cpu_ids is initialized
- * to NR_CPUS and isn't lowered until the possible cpus are
- * discovered (including any disabled cpus). So early uses
- * will span the entire range of NR_CPUS.
- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- *
- * The obsolescent cpumask operations are:
- *
- * void cpu_set(cpu, mask) turn on bit 'cpu' in mask
- * void cpu_clear(cpu, mask) turn off bit 'cpu' in mask
- * void cpus_setall(mask) set all bits
- * void cpus_clear(mask) clear all bits
- * int cpu_isset(cpu, mask) true iff bit 'cpu' set in mask
- * int cpu_test_and_set(cpu, mask) test and set bit 'cpu' in mask
- *
- * int cpus_and(dst, src1, src2) dst = src1 & src2 [intersection]
- * void cpus_or(dst, src1, src2) dst = src1 | src2 [union]

- * (can be used as an lvalue)
- * CPU_MASK_ALL Initializer - all bits set
- * CPU_MASK_NONE Initializer - no bits set
- * unsigned long *cpus_addr(mask) Array of unsigned long's in mask
- *
- * CPUMASK_ALLOC kmalloc's a structure that is a composite of many cpumask_t
- * variables, and CPUMASK_PTR provides pointers to each field.
- *
- * The structure should be defined something like this:
- * struct my_cpumasks {
- * cpumask_t mask1;
- * cpumask_t mask2;
- * };
- *
- * Usage is then:
- * CPUMASK_ALLOC(my_cpumasks);
- * CPUMASK_PTR(mask1, my_cpumasks);
- * CPUMASK_PTR(mask2, my_cpumasks);
- *
