So there is no this kind of problem for Vulkan application. It’s kind of “atomic” operation to enable SPM and update SPM_VMID. Vulkan application even is not aware of SPM_VMID. If there is any other UMD applications, such as OCL, and OCL driver doesn’t update the SPM_VMID before enable SPM, there is VMFault anyway even Vulkan driver restore the SPM_VMID to 0. <o:p> </o:p> Thanks<o:p></o:p> Jacob<o:p></o:p> <o:p> </o:p> <div style="mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in"> From: <a href="mailto:Christian.Koenig@amd.com">Koenig, Christian</a> Sent: Tuesday, February 25, 2020 2:51 AM To: <a href="mailto:Jacob.He@amd.com">He, Jacob</a>; <a href="mailto:David1.Zhou@amd.com"> Zhou, David(ChunMing)</a>; <a href="mailto:Alexander.Deucher@amd.com">Deucher, Alexander</a>; <a href="mailto:ckoenig.leichtzumerken@gmail.com">Christian König</a>; <a href="mailto:amd-gfx@lists.freedesktop.org"> amd-gfx@lists.freedesktop.org</a> Subject: Re: [PATCH] drm/amdgpu: Add a chunk ID for spm trace </div> <o:p> </o:p> Leave the old spm_vmid there is not a problem because other new spm enabled job will update it before it’s running and other spm disabled job will not access spm_vmid register.<o:p></o:p> Do you have a high level description of how SPM works?

Well there are multiple problems with that patch. First of all you need to better describe what SPM tracing is in the commit message. Then the updating of mmRLC_SPM_MC_CNTL must be executed asynchronously on the ring. Otherwise we might corrupt an already executing SPM trace. And you also need to make sure to disable the tracing again or otherwise we run into a bunch of trouble when the VMID is reused. You also need to make sure that IBs using the SPM trace are serialized with each other, e.g. hack into amdgpu_ids.c file and make sure that only one VMID at a time can have that attribute.
