2023-10-31drm/nouveau/gsp/r535: add support for booting GSP-RMBen Skeggs
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.

2023-09-19drm/nouveau/kms: Add INHERIT ioctl to nvkm/nvif for reading IOR stateLyude Paul
Now that we're supporting things like Ada and the GSP, there's situations where we really need to actually know the display state that we're starting with when loading the driver in order to prevent breaking GSP expectations. The first step in doing this is making it so that we can read the current state of IORs from nvkm in DRM, so that we can fill in said into into the atomic state. We do this by introducing an INHERIT ioctl to nvkm/nvif. This is basically another form of ACQUIRE, except that it will only acquire the given output path for userspace if it's already set up in hardware. This way, we can go through and probe each outp object we have in DRM in order to figure out the current hardware state of each one. If the outp isn't in use, it simply returns -ENODEV. This is also part of the work that will be required for implementing GSP support for display. While the GSP should mostly work without this commit, this commit should fix some edge case bugs that can occur on initial driver load. This also paves the way for some of the initial groundwork for fastboot support.

2023-09-19drm/nouveau/gr/gf100-: lose contents of global ctxbufs across suspendBen Skeggs
Some of these buffers are quite large, and there's no need to preserve them across suspend. Mark the contents as lost to speedup suspend/resume.

2023-09-15drm/nouveau/pm: refactor deprecated strncpyJustin Stitt
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We should prefer more robust and less ambiguous string interfaces. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding.
