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.

2025-05-19drm/nouveau/gsp: switch to a simpler GSP-RM header layoutBen Skeggs
Rather than using OpenRM's directory structure for headers, move to a layout that's split roughly around RM API boundaries. Also move the headers from include/nvrm to subdev/gsp/rm/r535/nvrm, with the rest of the r535-specific code.

2025-05-19drm/nouveau/gsp: remove gsp-specific chid allocation pathBen Skeggs
In order to specify a channel ID to RM during channel allocation, the channel ID is broken down into a "userd page" index and an index into that page. It was assumed that RM would enforce that the same physical block of memory be used for all CHIDs within a "userd page", and the GSP paths override NVKM's normal CHID allocation to handle this. However, none of that turns out to be necessary. Remove the GSP-specific code and use the regular CHID allocation path.

2025-05-15Revert "udmabuf: fix vmap_udmabuf error page set"Huan Yang
This reverts commit 18d7de823b7150344d242c3677e65d68c5271b04. We cannot use vmap_pfn() in vmap_udmabuf() as it would fail the pfn_valid() check in vmap_pfn_apply(). This is because vmap_pfn() is intended to be used for mapping non-struct-page memory such as PCIe BARs. Since, udmabuf mostly works with pages/folios backed by shmem/hugetlbfs/THP, vmap_pfn() is not the right tool or API to invoke for implementing vmap.
