[RFC v7 00/11] 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
