(In reply to Imre Deak from comment #6) > Could you give a try to the following: > http://lists.freedesktop.org/archives/intel-gfx/2014-November/055832.html With this patch, I run 10 time about gem_concurrent_blit, didn't reproduce this issue.
Because of this bug, QA disabled 131 IGT cases.
It also happenes on SKL. igt/gem_concurrent_blit/cpu-rcs-gpu-read-after-write-forked igt/gem_concurrent_blit/gpu-rcs-gpu-read-after-write igt/gem_concurrent_blit/gpu-rcs-gpu-read-after-write-forked igt/gem_concurrent_blit/gpu-rcs-gpu-read-after-write-interruptible igt/gem_concurrent_blit/gpu-rcs-overwrite-source-interruptible igt/gem_concurrent_blit/gtt-rcs-early-read-forked igt/gem_concurrent_blit/gtt-rcs-early-read-interruptible igt/gem_concurrent_blit/gtt-rcs-gpu-read-after-write-forked igt/gem_concurrent_blit/gtt-rcs-gpu-read-after-write-interruptible igt/gem_concurrent_blit/prw-rcs-gpu-read-after-write-interruptible igt/gem_concurrent_blit/prw-rcs-overwrite-source-forked igt/gem_concurrent_blit/prw-rcs-overwrite-source-interruptible igt/gem_render_linear_blits igt/gem_render_tiled_blits

@Imre Deak On 2014-11-20, QA tested your patch, the result shows positive, will you plan to merge up your patch? Thanks.

It's been merged since a long time: commit 2837ac40698d0931727b957a40c8c8ea27c3bcb2 Author: Imre Deak <imre.deak@intel.com> Date: Wed Nov 19 16:25:38 2014 +0200 drm/i915: vlv: increase timeout when setting idle GPU freq But this will only work for byt, so you need to file a new bug for snb/skl.
Tested gem_concurrent_blit on SNG and BYT with the latest nightly kernel and latest igt . All subcases successfully pass. I will test the gem_evict_everything case next week.
