Ok, fine by me /Monk From: Quan, Evan Sent: 2018å¹´3æ??27æ?¥ 9:34 To: Deucher, Alexander <Alexander.Deucher at amd.com>; Liu, Monk <Monk.Liu at amd.com>; Michel Dänzer <michel at daenzer.net> Cc: amd-gfx at lists.freedesktop.org; Koenig, Christian <Christian.Koenig at amd.com> Subject: RE: [PATCH] drm/amdgpu: no job timeout setting on compute queues Hi Monk, Thatâ??s a fix reached after a long discussion(I believe you were in that mail thread). 50s is for the dgemm test. We are not sure whether itâ??s enough for other compute use case. If virtualization still needs these messages, I believe we can list that as an exception - (ring->funcs->type == AMDGPU_RING_TYPE_COMPUTE) ? + /* for non-sriov case, no timeout enforce on compute ring */ + ((ring->funcs->type == AMDGPU_RING_TYPE_COMPUTE) && !amdgpu_sriov_vf(ring->adev)) ?

Or make them DRM_INFO.

I donâ??t think itâ??s a good idea to disable the time out message for compute ring, we have virtualization end-user Still want those message printed out Can you do this way ? In amdgpu_job_timeout, you can use DRM_WARN to replace DRM_ERROR for the job belongs to CPC engine ? /Monk From: amd-gfx [mailto:amd-gfx-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Quan, Evan Sent: 2018å¹´3æ??19æ?¥ 9:47 To: Deucher, Alexander <Alexander.Deucher at amd.com<mailto:Alexander.Deucher at amd.com>>; Michel Dänzer <michel at daenzer.net<mailto:michel at daenzer.net>> Cc: amd-gfx at lists.freedesktop.org<mailto:amd-gfx at lists.freedesktop.org> Subject: RE: [PATCH] drm/amdgpu: no job timeout setting on compute queues Thatâ??s fine for me.

Wouldn't that be rather surprising for somebody who sets amdgpu.gpu_recovery=1 ? -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer -------------- next part -------------- An HTML attachment was scrubbed...
