Hi,
These are libdrm_amdgpu patches harvested from an internal branch.
The first patch is a revert I had to make to fix the build. Yeah, sequence_mutex should be renamed to a more appropriate name. That can be done as a follow-up.
One notable change is the addition of DRM_IOCTL_AMDGPU_WAIT_FENCES. I hope the kernel contains (or will contain) the changes too, so that I don't push something that doesn't exist in the kernel.
Please let me know if these are okay to push.
Thanks,
