Hi all.
Just wondering if anyone else has tried to hibernate while using Radeon KMS
and a tree with Dave's post 2.6.34 patches? My 32 bit P4 based system (with
an RV250 card) is hanging at the atomic copy, with the following backtrace
hibernation_snapshot
dpm_suspend_start
async_synchronize_full
async_synchronize_cookie
async_synchronize_cookie_domain
I've been trying to bisect, but this computer is being painfully slow, so I
haven't been making much progress. 2.6.34 with the same config is fine, and
my bisection progress so far seems to be pointing at the merge I mentioned
above.
The only thing I can think off might be the output polling task, or
the fix from Jerome for AGP suspend/resume
10b06122afcc78468bd1d009633cb71e528acdc5 is AGP one to test
Thanks for the quick reply. I've commented out the radeon_agp_suspend
call and will try that shortly. By the way, saw your recent commit
message talking about kids programs and lowering of IQs. I sympathise. I
have the Wiggles in my head far too much at the moment :)
disabling output polling is a messier revert, might be easier to just edit
drivers/gpu/drm/drm_crtc_helper.c:drm_kms_helper_poll_init and remove
the delayed_slow_work_enqueue call, also forcing repoll to false
inside output_poll_execute which should in theory stop the polling
from starting or being kicked off later.
Will try that next.
I'll try and recreate if I get a chance, cc'ing dri-devel also for Alex/Jerome.
Ta.
Nigel
