drm/amdgpu: Add IP block soft reset as a GPU recovery method 2026-07-01T15:14:11+00:00 Timur Kristóf timur.kristof@gmail.com 2026-06-17T19:14:22+00:00 1fc76380c6ce5440e3cd02ddec76067f83969dc0 Implement IP block soft reset as a recovery method that fits into the current GPU recovery code as opposed to being hacked into the full GPU reset code path. This can gracefully handle GPU hangs when other reset methods are not available or have failed. It makes sure to minimize collateral damage (ie. affected non-guilty jobs) and does a backup and restore on all affected queues. Note that some of the new helpers may be useful for other reset types as well, which we can explore later.

drm/amdgpu: enumerate UMSCH HW IP 2026-06-17T20:24:20+00:00 Ruijing Dong ruijing.dong@amd.com 2026-06-12T18:39:31+00:00 c18cd8d6e008ab7d5bda784f583772bed8dbf5ca This part enumerates a UMSCH block under hardware id (22) at version 2.2.0 rather than under VCN. Add the UMSCH hardware id, an IP enum slot, and the discovery name/map entries so it is recognized. No IP block is wired up yet; this only makes the IP discoverable. The multimedia IP setup assumed VCN/VCE/UVD was always present; handle the case where it is absent so init does not fail with -EINVAL.
