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.

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 +

+ 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.
