1 driver/acpi/hotkey.c implement:
2 1. /proc/acpi/hotkey/event_config
3 (event based hotkey or event config interface):
4 a. add a event based hotkey(event) :
5 echo "0:bus::action:method:num:num" > event_config
7 b. delete a event based hotkey(event):
8 echo "1:::::num:num" > event_config
10 c. modify a event based hotkey(event):
11 echo "2:bus::action:method:num:num" > event_config
13 2. /proc/acpi/hotkey/poll_config
14 (polling based hotkey or event config interface):
15 a.add a polling based hotkey(event) :
16 echo "0:bus:method:action:method:num" > poll_config
17 this adding command will create a proc file
18 /proc/acpi/hotkey/method, which is used to get
19 result of polling.
21 b.delete a polling based hotkey(event):
22 echo "1:::::num" > event_config
24 c.modify a polling based hotkey(event):
25 echo "2:bus:method:action:method:num" > poll_config
27 3./proc/acpi/hotkey/action
28 (interface to call aml method associated with a
29 specific hotkey(event))
30 echo "event_num:event_type:event_argument" >
31 /proc/acpi/hotkey/action.
32 The result of the execution of this aml method is
33 attached to /proc/acpi/hotkey/poll_method, which is dynamically
34 created. Please use command "cat /proc/acpi/hotkey/polling_method"
35 to retrieve it.
37 Note: Use cmdline "acpi_generic_hotkey" to over-ride
38 platform-specific with generic driver.
