            Bug ID: 106466
           Summary: GPU recovery fails on Vega 64
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

dmesg

Reproduce:

1) boot
2) Start X
3) Stop X
4) cat /sys/kernel/debug/dri/2/amdgpu_gpu_recovery
5) Wait till finished
6) Start X
7) Notice slowness
8) Stop X

The dmesg says that the reset failed, but the screen comes back with some
artifacts. drawing in X is very slow event though pp_dpm_sclk seems to be
indicating reasonable speeds.

I use amd-staging-drm-next as of today with as last commit

commit 905aa01b240f9216b6dbba3226bf10b2d96eebb7 (origin/amd-staging-drm-next)

    drm/amd/display: clean up assignment of amdgpu_crtc

    The declaration of pointer amdgpu_crtc has a redundant assignment to
    amdgpu_crtc. Clean this up by removing it.

    Detected by CoverityScan, CID#1460299 ("Evaluation order violation")

plus a patch of my own adding some more dev_info messages to the reset process.
