Hi,
Some GPU hangs are reported on PowerPC with some dGPUs. This patch is
reported [1] to improve them:
commit 0ef2803173f1 ("drm/amdgpu/vcn1: read back register after written")
The other VCN versions are already in 6.15.9, this one didn't come back
though AFAICT.
Can you take it back to remaining stable trees?

What specific ones? 5.15.y is end-of-life, and this didn't apply to
5.12.y :(
