drm/amdgpu: Fix RAS page retirement with mode2 reset on Aldebaran 2021-10-13T18:14:48+00:00 Mukul Joshi mukul.joshi@amd.com 2021-09-21T00:48:23+00:00 91a1a52d03aa0f1f2b51c7df8a7bf437e906e29f During mode2 reset, the GPU is temporarily removed from the mgpu_info list. As a result, page retirement fails because it cannot find the GPU in the GPU list. To fix this, create our own list of GPUs that support MCE notifier based page retirement and use that list to check if the UMC error occurred on a GPU that supports MCE notifier based page retirement.
