1 What: /sys/kernel/debug/ec/*/{gpe,use_global_lock,io}
3 Contact: Thomas Renninger <trenn@suse.de>
6 General information like which GPE is assigned to the EC and whether
7 the global lock should get used.
8 Knowing the EC GPE one can watch the amount of HW events related to
9 the EC here (XY -> GPE number from /sys/kernel/debug/ec/*/gpe):
10 /sys/firmware/acpi/interrupts/gpeXY
12 The io file is binary and a userspace tool located here:
13 ftp://ftp.suse.com/pub/people/trenn/sources/ec/
14 should get used to read out the 256 Embedded Controller registers
17 CAUTION: Do not write to the Embedded Controller if you don't know
18 what you are doing! Rebooting afterwards also is a good idea.
19 This can influence the way your machine is cooled and fans may
20 not get switched on again after you did a wrong write.
