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.

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.

2025-04-23PCI: Add CONFIG_MMU dependencyArnd Bergmann
It turns out that there are no platforms that have PCI but don't have an MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing kernels for those platforms a lot, and avoids a lot of inadvertent build regressions. Add a dependency for CONFIG_PCI and remove all the ones for PCI specific device drivers that are currently marked not having it. There are a few platforms that have an optional MMU, but they usually cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is mainly for historic reasons, and anyone using those chips should really use the MMU these days.

2025-04-23drm/nouveau: Fix WARN_ON in nouveau_fence_context_kill()Philipp Stanner
Nouveau is mostly designed in a way that it's expected that fences only ever get signaled through nouveau_fence_signal(). However, in at least one other place, nouveau_fence_done(), can signal fences, too. If that happens (race) a signaled fence remains in the pending list for a while, until it gets removed by nouveau_fence_update(). Should nouveau_fence_context_kill() run in the meantime, this would be a bug because the function would attempt to set an error code on an already signaled fence. Have nouveau_fence_context_kill() check for a fence being signaled.

This has caused a small amount of fallout - two or three issues were reported. In all cases the calling code was found to be incorrect. - The series "Some cleanup for memcg" from Chen Ridong implements some relatively monir cleanups for the memcontrol code. - The series "mm: fixes for device-exclusive entries (hmm)" from David Hildenbrand fixes a boatload of issues which David found then using device-exclusive PTE entries when THP is enabled. More work is needed, but this makes thins better - our own HMM selftests now succeed. - The series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed remove the z3fold and zbud implementations. They have been deprecated for half a year and nobody has complained. - The series "mm: further simplify VMA merge operation" from Lorenzo Stoakes implements numerous simplifications in this area. No runtime effects are anticipated. - The series "mm/madvise: remove redundant mmap_lock operations from process_madvise()" from SeongJae Park rationalizes the locking in the madvise() implementation. Performance gains of 20-25% were observed in one MADV_DONTNEED microbenchmark. - The series "Tiny cleanup and improvements about SWAP code" from Baoquan He contains a number of touchups to issues which Baoquan noticed when working on the swap code. - The series "mm: kmemleak: Usability improvements" from Catalin Marinas implements a couple of improvements to the kmemleak user-visible output. - The series "mm/damon/paddr: fix large folios access and schemes handling" from Usama Arif provides a couple of fixes for DAMON's handling of large folios. - The series "mm/damon/core: fix wrong and/or useless damos_walk() behaviors" from SeongJae Park fixes a few issues with the accuracy of kdamond's walking of DAMON regions. - The series "expose mapping wrprotect, fix fb_defio use" from Lorenzo Stoakes changes the interaction between framebuffer deferred-io and core MM. No functional changes are anticipated - this is preparatory work for the future removal of page structure fields. - The series "mm/damon: add support for hugepage_size DAMOS filter" from Usama Arif adds a DAMOS filter which permits the filtering by huge page sizes. - The series "mm: permit guard regions for file-backed/shmem mappings" from Lorenzo Stoakes extends the guard region feature from its present "anon mappings only" state. The feature now covers shmem and file-backed mappings. - The series "mm: batched unmap lazyfree large folios during reclamation" from Barry Song cleans up and speeds up the unmapping for pte-mapped large folios. - The series "reimplement per-vma lock as a refcount" from Suren Baghdasaryan puts the vm_lock back into the vma. Our reasons for pulling it out were largely bogus and that change made the code more messy. This patchset provides small (0-10%) improvements on one microbenchmark. - The series "Docs/mm/damon: misc DAMOS filters documentation fixes and improves" from SeongJae Park does some maintenance work on the DAMON docs. - The series "hugetlb/CMA improvements for large systems" from Frank van der Linden addresses a pile of issues which have been observed when using CMA on large machines. - The series "mm/damon: introduce DAMOS filter type for unmapped pages" from SeongJae Park enables users of DMAON/DAMOS to filter my the page's mapped/unmapped status. - The series "zsmalloc/zram: there be preemption" from Sergey Senozhatsky teaches zram to run its compression and decompression operations preemptibly. - The series "selftests/mm: Some cleanups from trying to run them" from Brendan Jackman fixes a pile of unrelated issues which Brendan encountered while runnimg our selftests. - The series "fs/proc/task_mmu: add guard region bit to pagemap" from Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to determine whether a particular page is a guard page. - The series "mm, swap: remove swap slot cache" from Kairui Song removes the swap slot cache from the allocation path - it simply wasn't being effective. - The series "mm: cleanups for device-exclusive entries (hmm)" from David Hildenbrand implements a number of unrelated cleanups in this code. - The series "mm: Rework generic PTDUMP configs" from Anshuman Khandual implements a number of preparatoty cleanups to the GENERIC_PTDUMP Kconfig logic. - The series "mm/damon: auto-tune aggregation interval" from SeongJae Park implements a feedback-driven automatic tuning feature for DAMON's aggregation interval tuning. - The series "Fix lazy mmu mode" from Ryan Roberts fixes some issues in powerpc, sparc and x86 lazy MMU implementations.

Fix this by moving the drm_prime_gem_destroy call from nouveau_gem_object_del to nouveau_bo_del_ttm. This ensures that it will be run after ttm_bo_delayed_delete.

2025-03-17mm: allow compound zone device pagesAlistair Popple
Zone device pages are used to represent various type of device memory managed by device drivers. Currently compound zone device pages are not supported. This is because MEMORY_DEVICE_FS_DAX pages are the only user of higher order zone device pages and have their own page reference counting. A future change will unify FS DAX reference counting with normal page reference counting rules and remove the special FS DAX reference counting. Supporting that requires compound zone device pages. Supporting compound zone device pages requires compound_head() to distinguish between head and tail pages whilst still preserving the special struct page fields that are specific to zone device pages. A tail page is distinguished by having bit zero being set in page->compound_head, with the remaining bits pointing to the head page. For zone device pages page->compound_head is shared with page->pgmap. The page->pgmap field must be common to all pages within a folio, even if the folio spans memory sections. Therefore pgmap is the same for both head and tail pages and can be moved into the folio and we can use the standard scheme to find compound_head from a tail page.

2025-03-16mm/rmap: convert make_device_exclusive_range() to make_device_exclusive()David Hildenbrand
The single "real" user in the tree of make_device_exclusive_range() always requests making only a single address exclusive. The current implementation is hard to fix for properly supporting anonymous THP / large folios and for avoiding messing with rmap walks in weird ways. So let's always process a single address/page and return folio + page to minimize page -> folio lookups. This is a preparation for further changes. Reject any non-anonymous or hugetlb folios early, directly after GUP. While at it, extend the documentation of make_device_exclusive() to clarify some things.

2025-03-09drm/nouveau/nvkm: introduce new GSP reply policy NVKM_GSP_RPC_REPLY_POLLZhi Wang
Some GSP RPC commands need a new reply policy: "caller don't care about the message content but want to make sure a reply is received". To support this case, a new reply policy is introduced. NV_VGPU_MSG_FUNCTION_ALLOC_MEMORY is a large GSP RPC command. The actual required policy is NVKM_GSP_RPC_REPLY_POLL. This can be observed from the dump of the GSP message queue. After the large GSP RPC command is issued, GSP will write only an empty RPC header in the queue as the reply. Without this change, the policy "receiving the entire message" is used for NV_VGPU_MSG_FUNCTION_ALLOC_MEMORY. This causes the timeout of receiving the returned GSP message in the suspend/resume path. Introduce the new reply policy NVKM_GSP_RPC_REPLY_POLL, which waits for the returned GSP message but discards it for the caller. Use the new policy NVKM_GSP_RPC_REPLY_POLL on the GSP RPC command NV_VGPU_MSG_FUNCTION_ALLOC_MEMORY.

2025-03-09drm/nouveau/nvkm: factor out current GSP RPC command policiesZhi Wang
There can be multiple cases of handling the GSP RPC messages, which are the reply of GSP RPC commands according to the requirement of the callers and the nature of the GSP RPC commands. The current supported reply policies are "callers don't care" and "receive the entire message" according to the requirement of the callers. To introduce a new policy, factor out the current RPC command reply polices. Also, centralize the handling of the reply in a single function. Factor out NVKM_GSP_RPC_REPLY_NOWAIT as "callers don't care" and NVKM_GSP_RPC_REPLY_RECV as "receive the entire message". Introduce a kernel doc to document the policies. Factor out r535_gsp_rpc_handle_reply(). No functional change is intended for small GSP RPC commands. For large GSP commands, the caller decides the policy of how to handle the returned GSP RPC message.

2025-02-27drm/nouveau: Avoid multiple -Wflex-array-member-not-at-end warningsGustavo A. R. Silva
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with flexible-array members in the middle of other structs, we use the `struct_group_tagged()` helper to separate the flexible arrays from the rest of the members in the flexible structures. We then use the newly created tagged `struct nvif_ioctl_v0_hdr` and `struct nvif_ioctl_mthd_v0_hdr` to replace the type of the objects causing trouble in multiple structures. We also want to ensure that when new members need to be added to the flexible structures, they are always included within the newly created tagged structs. For this, we use `static_assert()`. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. So, with these changes, fix the following warnings: drivers/gpu/drm/nouveau/nvif/object.c:60:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:233:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:214:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:152:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:138:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nvif/object.c:104:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nouveau_svm.c:83:35: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/gpu/drm/nouveau/nouveau_svm.c:82:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.
