Bug ID: 63391 Summary: Radeon RS880 doesn't resume from suspend with radeon dpm enabled Product: Drivers Version: 2.5 Kernel Version: 3.12-rc5 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: tasev.stefanoska@skynet.be Regression: No
Created attachment 111831 --> https://bugzilla.kernel.org/attachment.cgi?id=111831&action=edit Dmesg 3.12-rc5 with dpm enabled
Hi,
I found last week that my system with radeon RS880 doesn't resume from suspend with radeon dpm enabled with kernel 3.12-rc5. Then i tested with kernel 3.12-rc2 to 3.12-rc4 this weekend with the same result. If i remove radeon.dpm=1 from the command line in grub then everything works fine (like always on this system). It works also fine with kernel 3.11 with dpm enabled. I found no errors in dmesg an Xorg.0.log, both are attached. The kernels are from the ubuntu kernel mainline ppa and i also try with a self compiled vanilla kernel.

Please append your working 3.11 dmesg and Xorg.0.log. Maybe comparison could help.

Can you bisect?

Hi,
I remember now that i was using 3-4 days 3.12-rc1 before i have reported this bug https://bugs.freedesktop.org/show_bug.cgi?id=70035 (gpu loockup) and the kernel was working fine. I just reinstalled 3.12-rc1 now and i will report later (maybe tomorow) if it works with dpm.
I also tested 3.12-rc6 this morning but with no success.
I'm reading about bisect the kernel now. Is this a good tutorial for starting ? : http://www.project-insanity.org/blog/2013/02/13/how-i-found-a-kernel-regress...

The 3.12-rc1 kernel is running fine with dpm enabled for more than 7 hours now with 10-15 suspend resume cycles.

--- Comment #8 from Tasev Nikola tasev.stefanoska@skynet.be --- Hi,
I start the bisect yesterday between 3.12-rc1 and 3.12-rc2. I will report when i'm finish.

I finish the bisect today, here is the result.
1cd8b21aa22c4fe8835abe614da5fa989c66dca9 is the first bad commit commit 1cd8b21aa22c4fe8835abe614da5fa989c66dca9 Author: Alex Deucher alexander.deucher@amd.com Date: Fri Sep 13 14:07:03 2013 -0400
drm/radeon/dpm: rework auto performance level enable
Calling force_performance_level() from set_power_state() doesn't work on some asics because the current power state pointer has not been properly updated at that point. Move the calls to force_performance_level() out of the asic specific set_power_state() functions and into the main power state sequence.
Fixes dpm resume on SI.

I don't understand much about but looking the commit i didn't see something related to RS880 .
Here is the git bisect log just in case it possibly help :

--- Comment #10 from Tasev Nikola tasev.stefanoska@skynet.be --- Hi,
I tested final 3.12 and the bug is still there. I 'm closing this bug because for me is not a big issue, i just disabled dpm and my system is stable. I hear that in next 3.13 kernel the dpm will be enabled by default, i hope that the kernel parameter will still exist so i can disable it. I don't no how to help moore to debug this so for now i'm closing this bug.
