Because rocm will need to release the drm descriptor to get amdgpu_amdkfd_device_fini_sw called, which would eventually call kgd2kfd_device_exit called. This would clean up kfd_topology at least. Otherwise I don’t see how it would be added back without messing

<p class="">Note that when you add back a new device, pci device and drm device are created, I am not an expert on KFD code but i believe also a new KFD device is created independent of the old one and so the topology should see just 2 device instances (one

Yes, regardless of the OOPS in ttm_bo_cleanup_refs, I plugged back the gpu, and I think it got probed all right, however the old kfd node is still there.</div>

<div class="">2. For unplanned hotplug when there is rocm app running, the patch that kill all processes and wait for 5 sec would work consistently. But it seems that it is an unacceptable solution for official release. I can hold it for our own internal usage.

 the hotplug test to try and catch them early). It would be best to run this branch on mi-100 so we have a clean baseline and only after confirming  this particular branch from this commits passes libdrm tests only then start adding the KFD specific addons.
 Another option if you can't work with MI-100 and this branch is to try a different ASIC that does work with this branch (if possible).</p>

OK I tried both this commit and the HEAD of and-staging-drm-next on two GPUs( MI100 and Radeon VII) both did not pass hotplugout libdrm test. I might be able to gain access to MI200, but I suspect it would work. </div>
