2022-11-09Merge branch '00.06-gr-ampere' of ↵Dave Airlie
https://gitlab.freedesktop.org/skeggsb/nouveau into drm-next This is the pull request for a whole bunch of fixes and prep-work that was done to support Ampere acceleration prior to GSP-RM being available. It uses the ACR firmware released by NVIDIA in linux-firmware, as we do on earlier GPUs. The work to support running on top of GSP-RM also heavily depends on various pieces of this series. In addition to the new HW support, general stability of the driver should be improved, especially around recovering HW from bugs that can be generated by userspace driver components.

Adds the start of common interfaces to load and boot the HS binaries provided by NVIDIA that enable the usage of GR. ACR already handles most of this, but it's very much tied into ACR's init process, and there's other code that could benefit from reusing a lot of this stuff too (ie. VBIOS DEVINIT/PreOS, VPR scrubber).
