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.

Description:	When read, this file returns the driver version.

		This attribute is used by the userland tools to find the sysfs-

		paths of installed kone-mice and determine the capabilites of
