Created attachment 111831 [details] dmesg ==System Environment== -------------------------- Regression: yes Non-working platforms: BDW ==kernel== -------------------------- drm-intel-nightly/07d0c831d9207c937595f081c8fddbddbf53756f commit 07d0c831d9207c937595f081c8fddbddbf53756f Author: Jani Nikula <jani.nikula@intel.com> Date: Tue Dec 30 15:02:01 2014 +0200 drm-intel-nightly: 2014y-12m-30d-13h-01m-34s UTC integration manifest ==Bug detailed description== ----------------------------- It's crash on BDW with drm-intel-nightly kernel and drm-intel-next-queued kernel. Bisect shows: 27401d126b5b1c8dd4df98bbb60b09ff2b3d5e60 is the first bad commit. This case also has bug 77869 and 84896. commit 27401d126b5b1c8dd4df98bbb60b09ff2b3d5e60 Author: Thomas Daniel <thomas.daniel@intel.com> AuthorDate: Thu Dec 11 12:48:35 2014 +0000 Commit: Daniel Vetter <daniel.vetter@ffwll.ch> CommitDate: Mon Dec 15 11:25:28 2014 +0100 drm/i915/bdw: Enable execlists by default where supported Execlist support in the i915 driver is now considered good enough for the feature to be enabled by default on Gen8 and later and routinely tested. Adjusted i915 parameters structure initialization to reflect this and updated the comment in intel_sanitize_enable_execlists(). There's still work to do before we can let the wider massive onto it, but there's still time left before the 3.20 cutoff. v2: Update the MODULE_PARM_DESC too. output: IGT-Version: 1.9-gcb512b6 (x86_64) (Linux: 3.19.0-rc2_drm-intel-nightly_07d0c8_20150105+ x86_64) Test assertion failure function intel_batchbuffer_flush_on_ring, file intel_batchbuffer.c:180: Failed assertion: (drm_intel_gem_bo_context_exec(batch->bo, ctx, used, ring)) == 0 Last errno: 16, Device or resource busy Subtest reset: FAIL (84.113s) Test assertion failure function loaded_check, file pm_rps.c:509: Failed assertion: freqs[CUR] == freqs[MAX] error: 450 != 900 Subtest reset: FAIL (87.116s) Test assertion failure function load_helper_stop, file pm_rps.c:290: Failed assertion: igt_wait_helper(&lh.igt_proc) == 0 Last errno: 10, No child processes pm_rps: igt_core.c:870: igt_fail: Assertion `!test_with_subtests || in_fixture' failed.

Please retest with commit 9ed67ab76f24ec1bf9b0414e3c8ac39c843f4d55 Author: Thomas Daniel <thomas.daniel@intel.com> Date: Wed Jan 7 16:09:30 2015 +0000 drm/i915: Reset CSB read pointer when enabling contexts
Strike that, please instead test this patch http://lists.freedesktop.org/archives/intel-gfx/2015-January/058125.html
It still fails with the patch. output: Test assertion failure function intel_batchbuffer_flush_on_ring, file intel_batchbuffer.c:180: Failed assertion: (drm_intel_gem_bo_context_exec(batch->bo, ctx, used, ring)) == 0 Last errno: 16, Device or resource busy Subtest reset: FAIL (84.118s) Test assertion failure function loaded_check, file pm_rps.c:509: Failed assertion: freqs[CUR] == freqs[MAX] error: 500 != 900 Subtest reset: FAIL (87.123s) Test assertion failure function load_helper_stop, file pm_rps.c:290: Failed assertion: igt_wait_helper(&lh.igt_proc) == 0 Last errno: 10, No child processes pm_rps: igt_core.c:880: igt_fail: Assertion `!test_with_subtests || in_fixture' failed.

add i915.enable_ppgtt=0,it works well. IGT-Version: 1.9-gbef692d (x86_64) (Linux: 3.19.0-rc5_drm-intel-nightly_98592c_20150122+ x86_64) Subtest reset: SUCCESS (45.260s)
Proposed fix is here : https://patchwork.kernel.org/patch/5833911/
The patch mentioned in commment #5 was merged. Please retest against -nightly.
pass with latest nightly branch b18ca534ab790c19aefe8ecbec46d1bc7a31ce1e(2015-02-26). Change state to verified.
