Hi Roland & vmwgfx maintainers,
Thomas has played around with these annotations on his vmwgfx setup,
and found some issues. Apparently in the atomic_commit_tail path when
handling the dirty rectangle stuff you acquire a ttm reservation,
which is a no-go since it could deadlock with other paths -
I need a canary in a ttm-based atomic driver to make sure the
dma_fence_begin/end_signalling annotations actually work.
