|
device. Writing this file with one of the strings from |

This file can be monitored for changes by polling for POLLPRI, |
|
POLLPRI will be signalled 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.
