BXT i915 error state
Setup:
* HW: BXT J4205, SKL GT2, KBL GT3e
* OS: Ubuntu 18.04
* kernel: drm-tip compiled from git
* GUI: Unity, using Mesa & Xorg compiled from git
Test-case:
1. Run GfxBench (v5) Driver2 offscreen benchmarks:
testfw_app --gfx glfw --gl_api desktop_core --width 1920 --height 1080
--fullscreen 1 --test_id gl_driver2_off
2. Run SynMark2 (v7) Batch5-7 tests
$ for t in 5 6 7; do synmark2 -homeDir $PWD OglBatch$t; done
Expected outcome:
* No GPU hangs, performance of each test-run is about same
Actual outcome:
* Every 5-10th run there's recoverable GPU hang and clearly lower perf
First time I saw this 15th of June. So the regression may have come between
following drm-tip commits:
* a0195925ba at 2019-06-14 16:19:08: drm-tip: 2019y-06m-14d-16h-18m-09s UTC
integration manifest
* 39e3d39be3 at 2019-06-15 15:21:37: drm-tip: 2019y-06m-15d-15h-20m-54s UTC
integration manifest
Notes:
* These are odd tests to be GPU hanging, as GPU functionality-wise they're
simple and more CPU than GPU bound</pre>
