...se a high-priority per-CRTC thread to accomplish this. [based off patches from Ville Syrj?l? <ville.syrjala at linux.intel.com>, change below to signoff later] Changes since v4: * Get rid of kthread interfaces we tried adding and move all of the locking into drm_vblank.c. For implementing drm_vblank_work_flush(), we now use a wait_queue and sequence counters in order to differentiate between multiple work item executions. * Get rid of drm_vblank_work_cancel() - this would have been pretty difficult to actually reimplement and it occurred to me that neither nouveau or i915 are even planning to use...

Nvidia released some documentation on how CRC support works on their GPUs, hooray! So: this patch series implements said CRC support in nouveau, along with adding some special debugfs interfaces for some relevant igt-gpu-tools tests (already on the ML). First - we add some new functionality to kthread_work in the kernel, and then use this to add a new feature to DRM that Ville Syrj?l? came up

Nvidia released some documentation on how CRC support works on their GPUs, hooray! So: this patch series implements said CRC support in nouveau, along with adding some special debugfs interfaces for some relevant igt-gpu-tools tests that we'll be sending in just a short bit. This additionally adds a feature that Ville Syrj?l? came up with: vblank works. Basically, this is just a generic DRM
