Description Eero Tamminen 2018-11-29 11:36:19 UTC
- FullHD monitor (through HDMI KVM)
- HadesCanyon KBL i7-8809G ([AMD/ATI] Vega [Radeon RX Vega M] (rev c0))
- Ubuntu 18.04
- drm-tip git kernel v4.20-rc4 (i.e. kernel.org v4.20-rc4 kernel + latest drm code from yesterday)
- Mesa git (c120dbfe4d) with AMD VEGAM renderer
- X server git version
- Proprietary GfxBench v5, but public GfxBench v4 should have same tests:

* Manhattan 3.0 offscreen:
  bin/testfw_app --gfx glfw --gl_api desktop_core --width 1920 --height 1080 --fullscreen 1 --test_id gl_manhattan_off
* Manhattan 3.1 onscreen:
  bin/testfw_app --gfx glfw --gl_api desktop_core --width 1920 --height 1080 --fullscreen 1 --test_id gl_manhattan31

Expected outcome:
* No GPU timeouts

Actual outcome:
* 1 out of 3 runs gives in dmesg:
[ 2817.689624] [drm:drm_sched_job_timedout [gpu_sched]] *ERROR* ring gfx timeout, but soft recovered

NOTE: These were happening already when we started testing this machine in mid October, with Mesa 18cc65edf8480 & drm-tip kernel v4.19-rc8.
