This series addresses GPU reset issues reported in [1], where running a long compute job would trigger repeated GPU resets, leading to a UI freeze.
Patches #1 and #2 prevent the same faulty job from being resubmitted in a loop, mitigating the first cause of the issue.
However, the issue isn't entirely solved. Even with only a single GPU reset, the UI still freezes on the Raspberry Pi 5, indicating a GPU hang. Patches #3 to #5 address this by properly configuring the V3D_SMS registers, which are required for power management and resets in V3D 7.1.
Patch #6 updates the DT maintainership, replacing Emma with the current v3d driver maintainer.
