Summary: R9285 4.17-wip locks/vmfaults since drm/amdgpu: revert
"drm/amdgpu: use AMDGPU_GEM_CREATE_VRAM_CLEARED for VM
Version: DRI git
last couple of agd5f 4.17-wips have locked with unreal tournament alpha for me
on R9 285.
Seems to be
first bad commit: [d712b817ceb9311cffad47867da26311c06a812b] drm/amdgpu: revert
"drm/amdgpu: use AMDGPU_GEM_CREATE_VRAM_CLEARED for VM PD/PTs" v2
Though it takes a while to lock, and sometimes only after restarting the game,
so slight chance of a false good.
This game requests slightly more than the 2 gig vram I have - maybe relevant if
others have more and can't reproduce.
Attached examples of logging retrieved after a lock. Usually sysrq will do,
once needed hard reset, first chunk got before a lock by quickly quitting the
game after seeing some new artifacts.
