driver/acpi/hotkey.c implement:
|
|
1. /proc/acpi/hotkey/event_config
|
|
(event based hotkey or event config interface):
|
|
a. add a event based hotkey(event) :
|
|
echo "0:bus::action:method:num:num" > event_config
|
|
|
|
b. delete a event based hotkey(event):
|
|
echo "1:::::num:num" > event_config
|
|
|
|
c. modify a event based hotkey(event):
|
|
echo "2:bus::action:method:num:num" > event_config
|
|
|
|
2. /proc/acpi/hotkey/poll_config
|
|
(polling based hotkey or event config interface):
|
|
a.add a polling based hotkey(event) :
|
|
echo "0:bus:method:action:method:num" > poll_config
|
|
this adding command will create a proc file
|
|
/proc/acpi/hotkey/method, which is used to get
|
|
result of polling.
|
|
|
|
b.delete a polling based hotkey(event):
|
|
echo "1:::::num" > event_config
|
|
|
|
c.modify a polling based hotkey(event):
|
|
echo "2:bus:method:action:method:num" > poll_config
|
|
|
|
3./proc/acpi/hotkey/action
|
|
(interface to call aml method associated with a
|
|
specific hotkey(event))
|
|
echo "event_num:event_type:event_argument" >
|
|
/proc/acpi/hotkey/action.
|
|
The result of the execution of this aml method is
|
|
attached to /proc/acpi/hotkey/poll_method, which is dnyamically
|
|
created. Please use command "cat /proc/acpi/hotkey/polling_method"
|
|
to retrieve it.
|
|
|
|
Note: Use cmdline "acpi_generic_hotkey" to over-ride
|
|
loading any platform specific drivers.
