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

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

Other gpu drivers have some driver-specific documentation, so it would nice if nouveau did as well. This adds a bare-bones ReStructured Text document with sections for module parameter documentation, an overview of the driver architecture, a section for internal API documentation, and a glossary for nouveau-specific terms. To make the document a little less bare, I've included docblocks for
