* drm/nouveau/gsp/r535: add support for booting GSP-RMBen Skeggs2023-10-314-0/+44
| | | | | | | | | | | | | This commit adds the initial code needed to boot the GSP-RM firmware provided by NVIDIA, bringing with it the beginnings of Ada support. Until it's had more testing and time to bake, support is disabled by default (except on Ada). GSP-RM usage can be enabled by passing the "config=NvGspRm=1" module option.

* drm/nouveau/flcn: new code to load+boot simple HS FWs (VPR scrubber)Ben Skeggs2022-11-094-0/+428
| | | | | | | | | | | | | | | | | | | 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). The VPR scrubber code is fairly independent, and a good first target. - adds better debug output to fw loading process, to ease bring-up/debug v2: - whitespace, 0->false Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>
