I'm new in this thread so I found the patch by myself. I hope it's the
right one:
http://www.spinics.net/lists/dri-devel/msg08028.html
But that patch doesn't apply to latest git, so I just added the seq_printf
call to the end of the swith of i915_drpc_info.
I finally found the way setup /sys/kernel/debug... My
/sys/kernel/debug/dri/0/i915_drpc_info is:
HD boost: no
Boost freq: 6
HW control enabled: no
SW control enabled: yes
Gated voltage change: no
Starting frequency: P5
Max P-state: P0
Min P-state: P7
RS1 VID: 0
RS2 VID: 8
Render standby enabled: yes
Current RS state: RS2 (RC6)
RSTDBYCTL: 0x474c3000
And there is a /sys/kernel/debug/dri/64/i915_drpc_info with the
same content. Whether X is running or not, the result is the same.
But even with d5bb081b027b52 reverted, the system could not resume
from suspend. I haven't checked it before so I've no idea about this.
Please keep me informed, thanks a lot ;-)
