-Acer Laptop WMI Extras Driver
-http://code.google.com/p/aceracpi
-Version 0.3
-4th April 2009
-
-Copyright 2007-2009 Carlos Corbacho <carlos@strangeworlds.co.uk>
-
-acer-wmi is a driver to allow you to control various parts of your Acer laptop
-hardware under Linux which are exposed via ACPI-WMI.
-
-This driver completely replaces the old out-of-tree acer_acpi, which I am
-currently maintaining for bug fixes only on pre-2.6.25 kernels. All development
-work is now focused solely on acer-wmi.
-
-Disclaimer
-**********
-
-Acer and Wistron have provided nothing towards the development acer_acpi or
-acer-wmi. All information we have has been through the efforts of the developers
-and the users to discover as much as possible about the hardware.
-
-As such, I do warn that this could break your hardware - this is extremely
-unlikely of course, but please bear this in mind.
-
-Background
-**********
-
-acer-wmi is derived from acer_acpi, originally developed by Mark
-Smith in 2005, then taken over by Carlos Corbacho in 2007, in order to activate
-the wireless LAN card under a 64-bit version of Linux, as acerhk[1] (the
-previous solution to the problem) relied on making 32 bit BIOS calls which are
-not possible in kernel space from a 64 bit OS.

-Supported Hardware
-******************
-
-NOTE: The Acer Aspire One is not supported hardware. It cannot work with
-acer-wmi until Acer fix their ACPI-WMI implementation on them, so has been
-blacklisted until that happens.
-
-Please see the website for the current list of known working hardware:
-
-http://code.google.com/p/aceracpi/wiki/SupportedHardware
-
-If your laptop is not listed, or listed as unknown, and works with acer-wmi,
-please contact me with a copy of the DSDT.
-
-If your Acer laptop doesn't work with acer-wmi, I would also like to see the
-DSDT.
-
-To send me the DSDT, as root/sudo:
-
-cat /sys/firmware/acpi/tables/DSDT > dsdt
-
-And send me the resulting 'dsdt' file.
-
-Usage
-*****
-
-On Acer laptops, acer-wmi should already be autoloaded based on DMI matching.
-For non-Acer laptops, until WMI based autoloading support is added, you will
-need to manually load acer-wmi.
-
-acer-wmi creates /sys/devices/platform/acer-wmi, and fills it with various
-files whose usage is detailed below, which enables you to control some of the
-following (varies between models):
-
-* the wireless LAN card radio
-* inbuilt Bluetooth adapter
-* inbuilt 3G card
-* mail LED of your laptop
-* brightness of the LCD panel
-
-Wireless
-********
-
-With regards to wireless, all acer-wmi does is enable the radio on the card. It
-is not responsible for the wireless LED - once the radio is enabled, this is
-down to the wireless driver for your card. So the behaviour of the wireless LED,
-once you enable the radio, will depend on your hardware and driver combination.
-
-e.g. With the BCM4318 on the Acer Aspire 5020 series:
-
-ndiswrapper: Light blinks on when transmitting
-b43: Solid light, blinks off when transmitting
-
-Wireless radio control is unconditionally enabled - all Acer laptops that support
-acer-wmi come with built-in wireless. However, should you feel so inclined to
-ever wish to remove the card, or swap it out at some point, please get in touch
-with me, as we may well be able to gain some data on wireless card detection.
-
-The wireless radio is exposed through rfkill.
-
-Bluetooth
-*********
-
-For bluetooth, this is an internal USB dongle, so once enabled, you will get
-a USB device connection event, and a new USB device appears. When you disable
-bluetooth, you get the reverse - a USB device disconnect event, followed by the
-device disappearing again.
-
-Bluetooth is autodetected by acer-wmi, so if you do not have a bluetooth module
-installed in your laptop, this file won't exist (please be aware that it is
-quite common for Acer not to fit bluetooth to their laptops - so just because
-you have a bluetooth button on the laptop, doesn't mean that bluetooth is
-installed).
-
-For the adventurously minded - if you want to buy an internal bluetooth
-module off the internet that is compatible with your laptop and fit it, then
-it will work just fine with acer-wmi.
-
-Bluetooth is exposed through rfkill.
-
-3G
-**
-
-3G is currently not autodetected, so the 'threeg' file is always created under
-sysfs. So far, no-one in possession of an Acer laptop with 3G built-in appears to
-have tried Linux, or reported back, so we don't have any information on this.
-
-If you have an Acer laptop that does have a 3G card in, please contact me so we
-can properly detect these, and find out a bit more about them.
-
-To read the status of the 3G card (0=off, 1=on):
-cat /sys/devices/platform/acer-wmi/threeg
-
-To enable the 3G card:
-echo 1 > /sys/devices/platform/acer-wmi/threeg
-
-To disable the 3G card:
-echo 0 > /sys/devices/platform/acer-wmi/threeg
-
-To set the state of the 3G card when loading acer-wmi, pass:
-threeg=X (where X is 0 or 1)
-
-Mail LED
-********
-
-This can be found in most older Acer laptops supported by acer-wmi, and many
-newer ones - it is built into the 'mail' button, and blinks when active.
-
-On newer (WMID) laptops though, we have no way of detecting the mail LED. If
-your laptop identifies itself in dmesg as a WMID model, then please try loading
-acer_acpi with:
-
-force_series=2490
-
-This will use a known alternative method of reading/ writing the mail LED. If
-it works, please report back to me with the DMI data from your laptop so this
-can be added to acer-wmi.
-
-The LED is exposed through the LED subsystem, and can be found in:
-
-/sys/devices/platform/acer-wmi/leds/acer-wmi::mail/
-
-The mail LED is autodetected, so if you don't have one, the LED device won't
-be registered.
-
-Backlight
-*********
-
-The backlight brightness control is available on all acer-wmi supported
-hardware. The maximum brightness level is usually 15, but on some newer laptops
-it's 10 (this is again autodetected).
-
-The backlight is exposed through the backlight subsystem, and can be found in:
-
-/sys/devices/platform/acer-wmi/backlight/acer-wmi/
