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

VBLANK handlers in struct drm_driver are deprecated. Only legacy, non-KMS drivers are supposed to used them. DRM drivers with kernel modesetting are supposed to use VBLANK callbacks of the CRTC infrastructure. This patchset converts all DRM drivers to CRTC VBLANK callbacks and cleans up struct drm_driver. The remaining VBLANK callbacks in struct drm_driver are only used by legacy drivers.

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
