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: improve handling of 64-bit BARsBen Skeggs
GPUs exist now with a 64-bit BAR0, which mean that BAR1 and BAR2's indices (as passed to pci_resource_len() etc) are bumped up by one. Modify nvkm_device.resource_addr/size() to take an enum instead of an integer bar index, and take IORESOURCE_MEM_64 into account when translating to the "raw" bar id.

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/pci: add PRI address of config space mirror to nvkm_pci_funcBen Skeggs
These registers have moved on GH100/GBxxx, and the GSP-RM init code uses hardcoded values from earlier GPUs to fill GspSystemInfo. Replace the per-GPU accessors in nvkm_pci_func with region info, and use it when initialising GspSystemInfo.

2025-05-19drm/nouveau/gsp: add support for 570.144Ben Skeggs
Add r570-specific HAL routines, and support loading of GSP-RM version 570.144 if firmware is available. There should be no impact on r535, or non-GSP paths.
