What: /sys/kernel/debug/ec/*/{gpe,use_global_lock,io} |
|
Date: July 2010 |
|
Contact: Thomas Renninger <[email protected]> |
|
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.
