Hi,
I tried latest drm-fixes today and saw a lot of these: Fallout from ttm rework?
Yes, I fixed this in d1a73c641afd2617bd80bce8b71a096fc5b74b7e it was in drm-misc-next in the drm-misc tree for a while but hasn’t been merged for 5.12.

Hmm, yes but doesn't that fix trip the ttm_bo_unpin() dma_resv_assert_held(bo->base.resv)?
No, doesn’t seem to. TBH I’m not sure why myself, but it seems to be working fine.
With CONFIG_PROVE_LOCKING=y I see this:
[ 7.117145] [drm] FIFO at 0x00000000fe000000 size is 8192 kiB
[ 7.117284] [drm] VRAM at 0x00000000e8000000 size is 131072 kiB
[ 7.117291] INFO: trying to register non-static key.
[ 7.117295] the code is fine but needs lockdep annotation.
[ 7.117298] turning off the locking correctness validator
Which will probably mask that dma_resv_assert_held(bo->base.resv)
