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

...* Mention in test_ctx_flip_detection() that we also explicitly check that we've skipped -exactly- one frame. tl;dr more then one frame is too slow, less then one frame means a context flip just didn't happen when it should have. * Also check that the flip threshold we set in test_ctx_flip_threshold_reset_after_capture() isn't ignored by the driver * s/(create|destroy)_colors()/\1_crc_colors/g Changes since v3: * Update .gitlab-ci.yml to make nouveau exempt from the test-list-diff test, since all the cool kids are doing it and we don't care about autotools for nouveau Changes since...

From: Lyude Paul <lyude at redhat.com> Nouveau has finally gotten CRC support, and at this point that support has made its way upstream. Hooray! So, let's start adding some relevant tests for it since nvidia's CRC implementation has some rather interesting design choices that needed to be worked around. Lyude Paul (5): lib/igt_core: Fix igt_assert_fd() documentation

From: Lyude Paul <lyude at redhat.com> Nouveau has finally gotten CRC support, hooray! Well, it's under review at least: https://patchwork.freedesktop.org/series/74804/ (it has a cover letter, but nouveau's mailing list configuration has blocked the email so I'm waiting for a moderator to fix that) So, this series adds the relevant tests for it since nvidia's CRC

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
