Hi all,
Finally gotten around to refreshing all the various fence anntotions I've hast last summer. Or well parts of it:
entire amdgpu and drm/scheduler annotations postponed for now, because there's way too many splats in there that need some work
in recent patches I've seen quite a few dma_resv_lock or kmalloc in atomic_commit_tail, which doesn't work in full generality with the rules for dma_fences we've discussed and encoded in lockdep. These annotations should catch stuff like this.
Review comments and testing very much welcome.
I pulled in the acked/reviewed patches into drm-misc-next. Testing (enable lockdep, test your driver) and review on the others very much appreciated.
Thanks, Daniel
Cheers, Daniel
