What: /sys/kernel/debug/ec/*/{gpe,use_global_lock,io}

Description:
|
|
|
|
General information like which GPE is assigned to the EC and whether
|
|
the global lock should get used.
|
|
Knowing the EC GPE one can watch the amount of HW events related to
|
|
the EC here (XY -> GPE number from `/sys/kernel/debug/ec/*/gpe`):
|
|
/sys/firmware/acpi/interrupts/gpeXY
|
|
|
|
The io file is binary and a userspace tool located here:
|
|
ftp://ftp.suse.com/pub/people/trenn/sources/ec/
|
|
should get used to read out the 256 Embedded Controller registers
|
|
or writing to them.
|
|
|
|
CAUTION:
|
|
Do not write to the Embedded Controller if you don't know
|
|
what you are doing! Rebooting afterwards also is a good idea.
|
|
This can influence the way your machine is cooled and fans may
|
|
not get switched on again after you did a wrong write.
