2025-05-19drm/nouveau: add support for GB20xBen Skeggs
This commit adds support for the GB20x GPUs found on GeForce RTX 50xx series boards. Beyond a few miscellaneous register moves and HW class ID plumbing, this reuses most of the code added to support GH100/GB10x.

2025-05-19drm/nouveau: add support for GB10xBen Skeggs
This commit enables basic support for the GB100/GB102 Blackwell GPUs. Beyond HW class ID plumbing there's very little change here vs GH100.

2025-05-19drm/nouveau: add support for GH100Ben Skeggs
This commit enables basic support for Hopper GPUs, and is intended primarily as a base supporting Blackwell GPUs, which reuse most of the code added here. Advanced features such as Confidential Compute are not supported. Beyond a few miscellaneous register moves and HW class ID plumbing, the bulk of the changes implemented here are to support the GSP-RM boot sequence used on Hopper/Blackwell GPUs, as well as a new page table layout. There should be no changes here that impact prior GPUs.

2025-05-19drm/nouveau/gsp: init client VMMs with NV0080_CTRL_DMA_SET_PAGE_DIRECTORYBen Skeggs
The current code using NV90F1_CTRL_CMD_VASPACE_COPY_SERVER_RESERVED_PDES not only requires changes to support the new page table layout used on Hopper/Blackwell GPUs, but is also broken in that it always mirrors the PDEs used for virtual address 0, rather than the area reserved for RM. This works fine for the non-NVK case where the kernel has full control of the VMM layout and things end up in the right place, but NVK puts its kernel reserved area much higher in the address space. Fixing the code to work at any VA is not enough as some parts of RM want the reserved area in a specific location, and NVK would then hit other assertions in RM instead. Fortunately, it appears that RM never needs to allocate anything within its reserved area for DRM clients, and the COPY_SERVER_RESERVED_PDES control call primarily serves to allow RM to locate the root page table when initialising a channel's instance block. Flag VMMs allocated by the DRM driver as externally owned, and use NV0080_CTRL_CMD_DMA_SET_PAGE_DIRECTORY to inform RM of the root page table in a similar way to NVIDIA's UVM driver. The COPY_SERVER_RESERVED_PDES paths are kept for the golden context image and gr scrubber channel, where RM needs the reserved area.

2025-05-19drm/nouveau/gsp: add common code for engines/engine objectsBen Skeggs
With minimal to no direct HW programming required, most nvkm_engine implementations are nearly identical when running on top of GSP-RM. Add a common implementation of the boilerplate, and use nvkm_rm_gpu to expose the correct class IDs. As they're now handled by common code, and there's no support for them prior to GSP-RM support - this deletes the GA100 NVDEC/NVJPG/OFA HALs, the GA102 NVENC/OFA HALs, and the AD102 GR/NVDEC/NVENC/NVJPG/OFA HALs.

2025-05-19drm/nouveau/gsp: add gpu hal stubsBen Skeggs
With GSP-RM handling the majority of the HW programming, NVKM's usual HALs are more elaborate than necessary, resulting in a fair amount of duplicated boilerplate. Adds 'nvkm_rm_gpu' which serves to provide GPU-specific constants and functions in a more streamlined manner. This is initially used in subsequent commits to store engine class IDs, and replace the per-engine/engobj boilerplate with common code for all GSP-RM supported engines - and is further extended when adding GH100, GB10x and GB20x support.
