Description: Reading this file gives the current selected profile for this
|
||
|
|
device. Writing this file with one of the strings from
|
||
|
|
platform_profile_choices changes the profile to the new value.
|
||
|
|
|
||
|
|
This file can be monitored for changes by polling for POLLPRI,
|
||
|
|
POLLPRI will be signaled on any changes, independent of those
|
||
|
|
changes coming from a userspace write; or coming from another
|
||
|
|
source such as e.g. a hotkey triggered profile change handled
|
||
|
|
either directly by the embedded-controller or fully handled
|
||
|
|
inside the kernel.
|
||
|
|
|
||
|
|
This file may also emit the string 'custom' to indicate
|
||
|
|
that the driver is using a driver defined custom profile.
