[RFC v4 00/12] drm/nouveau: Introduce CRC support for gf119+
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

[PATCH v2 00/21] drm: Clean up VBLANK callbacks in struct drm_driver
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.

So: this patch series implements said CRC support in nouveau, along with
