We expect this to fail on -nightly at the moment, but it should pass on -fixes. Can you please give the full details for the failure from -fixes?

It works well on -fixes kernel. Should be fixed by commit f833c65abf79c2456fe8e8c487e3d78b9c329daa Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Aug 26 11:23:47 2013 +0200 drm/i915: More vma fixups around unbind/destroy Following new cases also fails on PNV,ILK,IVB.HSW with -nightly and -queued kernel and works well on -fixes kernel. They also cause call trace on sandybridge with -nightly and -queued kernel. igt/gem_evict_alignment/minor-interruptible igt/gem_evict_alignment/minor-normal igt/gem_evict_everything/minor-interruptible igt/gem_evict_everything/minor-normal run ./gem_evict_alignment --run-subtest minor-interruptible output on ivb: Test assertion failure function copy, file gem_evict_alignment.c:117: Failed assertion: ret == error Subtest minor-interruptible: FAIL With latest -nightly all subcases should work. Please verify. It still happens on latest -nightly kernel. Created attachment 84765 [details]
dmesg on nightly
Assigning to Ben since apparently he can reproduce this. Created attachment 84792 [details] [review] Fix. Created attachment 84800 [details] [review] Fix, mk2. Created attachment 84818 [details] [review] Fix, mk3. By popular demand, here's the fixed spurious hunk. Please retest with latest drm-intel-nightly: commit a2420ab56204e8e86b1b56199daf19dfc2b4c43d Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Aug 29 19:50:31 2013 +0200 drm/i915: Fix list corruption in vma_unbind Fixed on latest -nightly branch. output: Subtest minor-normal: SUCCESS Test requirement not met in function major_evictions, file gem_evict_alignment.c:158: Test requirement: ((uint64_t)count * size / (1024 * 1024) < intel_get_total_ram_mb() * 9 / 10) Subtest major-normal: SKIP Subtest minor-interruptible: SUCCESS Test requirement not met in function major_evictions, file gem_evict_alignment.c:158: Test requirement: ((uint64_t)count * size / (1024 * 1024) < intel_get_total_ram_mb() * 9 / 10) Subtest major-interruptible: SKIP Ben, Chris: Do you still hit this oops or can we close this as fixed on latest -nightly? gem_evict_alignment still passes and I have not reproduced the error I saw elsewhere. I haven't reproduced the error either; I think it's safe to close, and QA can reopen if it pops back up. Ok, markging this as resolved then. Verified.Fixed. Moving old bug from Verified to Closed. |
