-What: /sys/kernel/debug/ec/*/{gpe,use_global_lock,io}
-Date: July 2010
-Contact: Thomas Renninger <trenn@suse.de>
-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.
