sourceTHIS IS VERY MUCH A WORK IN PROGRESS. NO WARRANTY GIVEN.This is a driver for laptops built by Compal:
Compal FL90/IFL90
Compal FL90/IFL90
Compal FL91/IFL91
Compal FL92/JFL92
Compal FT00/IFT00
Compal JHL90
Compal JHL91
Dell Mini 9
Dell Mini 10
Dell Mini 10v
Dell Inspiron 11z
Dell Mini 12
It adds support for:
- bluetooth, WLAN and lcd brightness control (via backlight control/rfkill)
- change battery charging level
This driver exports a few files in
/sys/devices/platform/compal-laptop/:
wlan - wlan subsystem state
current state
cat /sys/devices/platform/compal-laptop/rfkill0/state
disable wlan
echo 0 > /sys/devices/platform/compal-laptop/rfkill0/state
enable wlan
echo 1 > /sys/devices/platform/compal-laptop/rfkill0/state
or better - use some tools like
rfkill bluetooth - bluetooth subsystem state
current state
cat /sys/devices/platform/compal-laptop/rfkill1/state
disable bluetooth
echo 0 > /sys/devices/platform/compal-laptop/rfkill1/state
enable bluetooth
echo 1 > /sys/devices/platform/compal-laptop/rfkill1/state
or better - use some tools like
rfkill charging level - change battery charging level
current state
cat /sys/devices/platform/compal-laptop/charging_level
set charging level to 50%
echo 50 > /sys/devices/platform/compal-laptop/charging_level
set charging level to 75%
echo 75 > /sys/devices/platform/compal-laptop/charging_level
set charging level to 100%
echo 100 > /sys/devices/platform/compal-laptop/charging_level
or
echo 0 > /sys/devices/platform/compal-laptop/charging_level
controling backlight
get current backlight level
cat /sys/class/backlight/compal-laptop/actual_brightness
set backlight level to 4 (0-7, 4 mean 50%)
echo 4 > /sys/class/backlight/compal-laptop/brightness
This driver might work on other laptops produced by Compal. If you want to try it you can pass force=1 as argument to the module which will force it to load even when the DMI data doesn't identify the laptop as IFL90.
Tested on
Compal FL90+ PM2, bluetooth, Intel PRO/Wireless 4965 AGN, kernel 2.6.34, debian unstable.
