From: Lyude Paul <lyude at redhat.com> (Just forwarding this to nouveau's ml, since I completely forgot to before) 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)

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.
