[ICL / Iris] GPU hangs in GfxBench Aztec Ruins
Setup:
- HW: ICL-U D1
- OS: Ubuntu 18.04 with Unity desktop (compiz)
- SW: drm-tip 5.4-rc2 kernel and git version of X server & Mesa
- Desktop uses i965, benchmarks use Iris
Use-case:
- Run GfxBench Aztec Ruins GL version 3x:
bin/testfw_app --gfx glfw --gl_api desktop_core --width 1920 --height 1080 --fullscreen 1 --test_id gl_5_normal
Outcome:
- GPU hang(s), see attachment in #1882 (closed)
- Fails before outputting any FPS (whereas the other hanging tests still succeed despite the hangs)
Notes:
- According to Kenneth, it looks like compute hang
- No issues with i965 on ICL (or GEN9)
- Don't have data on whether it's ICL specific
This is split from #1882 (closed). It's potentially related to Iris/ICL/CSDof bug: #1368 (closed).
