2025-10-31drm: include drm_print.h where neededJani Nikula8-0/+11
There are a gazillion files that depend on drm_print.h being indirectly included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In preparation for removing those includes, explicitly include drm_print.h where needed.

Don't mix dma fence lock with the active_job lock. Use fence_lock to protect the dma fence used by drm scheduler when signalling a job completion and queue_lock to protect concurrent access to active bin job in OOM and stats collection for a given file priv.

2025-08-29drm/v3d: Protect per-fd reset counter against fd releaseMaíra Canal1-13/+17
The per-fd reset counter tracks GPU resets caused by jobs submitted through a specific file descriptor. However, there's a race condition where the file descriptor can be closed while jobs are still running, leading to potential access to freed memory when updating the reset counter. Ensure that the per-fd reset counter is only updated when the file descriptor is still valid, preventing use-after-free scenarios during GPU reset handling.

2025-08-29drm/v3d: Replace a global spinlock with a per-queue spinlockMaíra Canal5-21/+20
Each V3D queue works independently and all the dependencies between the jobs are handled through the DRM scheduler. Therefore, there is no need to use one single lock for all queues. Using it, creates unnecessary contention between different queues that can operate independently. Replace the global spinlock with per-queue locks to improve parallelism and reduce contention between different V3D queues (BIN, RENDER, TFU, CSD). This allows independent queues to operate concurrently while maintaining proper synchronization within each queue.

The below blurbiage describes 42 patchsets. 21 of those are partially or fully cleanup work. "cleans up", "cleanup", "maintainability", "rationalizes", etc. I never knew the MM code was so dirty. "mm: ksm: prevent KSM from breaking merging of new VMAs" (Lorenzo Stoakes) addresses an issue with KSM's PR_SET_MEMORY_MERGE mode: newly mapped VMAs were not eligible for merging with existing adjacent VMAs. "mm/damon: introduce DAMON_STAT for simple and practical access monitoring" (SeongJae Park) adds a new kernel module which simplifies the setup and usage of DAMON in production environments. "stop passing a writeback_control to swap/shmem writeout" (Christoph Hellwig) is a cleanup to the writeback code which removes a couple of pointers from struct writeback_control. "drivers/base/node.c: optimization and cleanups" (Donet Tom) contains largely uncorrelated cleanups to the NUMA node setup and management code. "mm: userfaultfd: assorted fixes and cleanups" (Tal Zussman) does some maintenance work on the userfaultfd code. "Readahead tweaks for larger folios" (Ryan Roberts) implements some tuneups for pagecache readahead when it is reading into order>0 folios. "selftests/mm: Tweaks to the cow test" (Mark Brown) provides some cleanups and consistency improvements to the selftests code. "Optimize mremap() for large folios" (Dev Jain) does that. A 37% reduction in execution time was measured in a memset+mremap+munmap microbenchmark. "Remove zero_user()" (Matthew Wilcox) expunges zero_user() in favor of the more modern memzero_page(). "mm/huge_memory: vmf_insert_folio_*() and vmf_insert_pfn_pud() fixes" (David Hildenbrand) addresses some warts which David noticed in the huge page code. These were not known to be causing any issues at this time. "mm/damon: use alloc_migrate_target() for DAMOS_MIGRATE_{HOT,COLD" (SeongJae Park) provides some cleanup and consolidation work in DAMON. "use vm_flags_t consistently" (Lorenzo Stoakes) uses vm_flags_t in places where we were inappropriately using other types. "mm/memfd: Reserve hugetlb folios before allocation" (Vivek Kasireddy) increases the reliability of large page allocation in the memfd code. "mm: Remove pXX_devmap page table bit and pfn_t type" (Alistair Popple) removes several now-unneeded PFN_* flags. "mm/damon: decouple sysfs from core" (SeongJae Park) implememnts some cleanup and maintainability work in the DAMON sysfs layer. "madvise cleanup" (Lorenzo Stoakes) does quite a lot of cleanup/maintenance work in the madvise() code. "madvise anon_name cleanups" (Vlastimil Babka) provides additional cleanups on top or Lorenzo's effort. "Implement numa node notifier" (Oscar Salvador) creates a standalone notifier for NUMA node memory state changes. Previously these were lumped under the more general memory on/offline notifier. "Make MIGRATE_ISOLATE a standalone bit" (Zi Yan) cleans up the pageblock isolation code and fixes a potential issue which doesn't seem to cause any problems in practice. "selftests/damon: add python and drgn based DAMON sysfs functionality tests" (SeongJae Park) adds additional drgn- and python-based DAMON selftests which are more comprehensive than the existing selftest suite. "Misc rework on hugetlb faulting path" (Oscar Salvador) fixes a rather obscure deadlock in the hugetlb fault code and follows that fix with a series of cleanups. "cma: factor out allocation logic from __cma_declare_contiguous_nid" (Mike Rapoport) rationalizes and cleans up the highmem-specific code in the CMA allocator. "mm/migration: rework movable_ops page migration (part 1)" (David Hildenbrand) provides cleanups and future-preparedness to the migration code. "mm/damon: add trace events for auto-tuned monitoring intervals and DAMOS quota" (SeongJae Park) adds some tracepoints to some DAMON auto-tuning code. "mm/damon: fix misc bugs in DAMON modules" (SeongJae Park) does that. "mm/damon: misc cleanups" (SeongJae Park) also does what it claims. "mm: folio_pte_batch() improvements" (David Hildenbrand) cleans up the large folio PTE batching code. "mm/damon/vaddr: Allow interleaving in migrate_{hot,cold} actions" (SeongJae Park) facilitates dynamic alteration of DAMON's inter-node allocation policy. "Remove unmap_and_put_page()" (Vishal Moola) provides a couple of page->folio conversions. "mm: per-node proactive reclaim" (Davidlohr Bueso) implements a per-node control of proactive reclaim - beyond the current memcg-based implementation. "mm/damon: remove damon_callback" (SeongJae Park) replaces the damon_callback interface with a more general and powerful damon_call()+damos_walk() interface. "mm/mremap: permit mremap() move of multiple VMAs" (Lorenzo Stoakes) implements a number of mremap cleanups (of course) in preparation for adding new mremap() functionality: newly permit the remapping of multiple VMAs when the user is specifying MREMAP_FIXED. It still excludes some specialized situations where this cannot be performed reliably. "drop hugetlb_free_pgd_range()" (Anthony Yznaga) switches some sparc hugetlb code over to the generic version and removes the thus-unneeded hugetlb_free_pgd_range(). "mm/damon/sysfs: support periodic and automated stats update" (SeongJae Park) augments the present userspace-requested update of DAMON sysfs monitoring files. Automatic update is now provided, along with a tunable to control the update interval. "Some randome fixes and cleanups to swapfile" (Kemeng Shi) does what is claims. "mm: introduce snapshot_page" (Luiz Capitulino and David Hildenbrand) provides (and uses) a means by which debug-style functions can grab a copy of a pageframe and inspect it locklessly without tripping over the races inherent in operating on the live pageframe directly. "use per-vma locks for /proc/pid/maps reads" (Suren Baghdasaryan) addresses the large contention issues which can be triggered by reads from that procfs file. Latencies are reduced by more than half in some situations. The series also introduces several new selftests for the /proc/pid/maps interface. "__folio_split() clean up" (Zi Yan) cleans up __folio_split()! "Optimize mprotect() for large folios" (Dev Jain) provides some quite large (>3x) speedups to mprotect() when dealing with large folios. "selftests/mm: reuse FORCE_READ to replace "asm volatile("" : "+r" (XXX));" and some cleanup" (wang lian) does some cleanup work in the selftests code. "tools/testing: expand mremap testing" (Lorenzo Stoakes) extends the mremap() selftest in several ways, including adding more checking of Lorenzo's recently added "permit mremap() move of multiple VMAs" feature.

2025-07-15drm/v3d: Use DRM_GPU_SCHED_STAT_NO_HANG to skip the resetMaíra Canal1-14/+2
When a CL/CSD job times out, we check if the GPU has made any progress since the last timeout. If so, instead of resetting the hardware, we skip the reset and allow the timer to be rearmed. This gives long-running jobs a chance to complete. Instead of manipulating scheduler's internals, inform the scheduler that the job did not actually timeout and no reset was performed through the new status code DRM_GPU_SCHED_STAT_NO_HANG.

2025-07-15drm/sched: Rename DRM_GPU_SCHED_STAT_NOMINAL to DRM_GPU_SCHED_STAT_RESETMaíra Canal1-3/+3
Among the scheduler's statuses, the only one that indicates an error is DRM_GPU_SCHED_STAT_ENODEV. Any status other than DRM_GPU_SCHED_STAT_ENODEV signifies that the operation succeeded and the GPU is in a nominal state. However, to provide more information about the GPU's status, it is needed to convey more information than just "OK". Therefore, rename DRM_GPU_SCHED_STAT_NOMINAL to DRM_GPU_SCHED_STAT_RESET, which better communicates the meaning of this status. The status DRM_GPU_SCHED_STAT_RESET indicates that the GPU has hung, but it has been successfully reset and is now in a nominal state again.

2025-06-29sanitize handling of long-term internal mountsAl Viro1-3/+18
Original rationale for those had been the reduced cost of mntput() for the stuff that is mounted somewhere. Mount refcount increments and decrements are frequent; what's worse, they tend to concentrate on the same instances and cacheline pingpong is quite noticable. As the result, mount refcounts are per-cpu; that allows a very cheap increment. Plain decrement would be just as easy, but decrement-and-test is anything but (we need to add the components up, with exclusion against possible increment-from-zero, etc.). Fortunately, there is a very common case where we can tell that decrement won't be the final one - if the thing we are dropping is currently mounted somewhere. We have an RCU delay between the removal from mount tree and dropping the reference that used to pin it there, so we can just take rcu_read_lock() and check if the victim is mounted somewhere. If it is, we can go ahead and decrement without and further checks - the reference we are dropping is not the last one. If it isn't, we get all the fun with locking, carefully adding up components, etc., but the majority of refcount decrements end up taking the fast path. There is a major exception, though - pipes and sockets. Those live on the internal filesystems that are not going to be mounted anywhere. They are not going to be _un_mounted, of course, so having to take the slow path every time a pipe or socket gets closed is really obnoxious. Solution had been to mark them as long-lived ones - essentially faking "they are mounted somewhere" indicator. With minor modification that works even for ones that do eventually get dropped - all it takes is making sure we have an RCU delay between clearing the "mounted somewhere" indicator and dropping the reference. There are some additional twists (if you want to drop a dozen of such internal mounts, you'd be better off with clearing the indicator on all of them, doing an RCU delay once, then dropping the references), but in the basic form it had been * use kern_mount() if you want your internal mount to be a long-term one. * use kern_unmount() to undo that. Unfortunately, the things did rot a bit during the mount API reshuffling. In several cases we have lost the "fake the indicator" part; kern_unmount() on the unmount side remained (it doesn't warn if you use it on a mount without the indicator), but all benefits regaring mntput() cost had been lost. To get rid of that bitrot, let's add a new helper that would work with fs_context-based API: fc_mount_longterm(). It's a counterpart of fc_mount() that does, on success, mark its result as long-term. It must be paired with kern_unmount() or equivalents.

When the job completes, we update the global GPU stats and the per-fd GPU stats, which are exposed through fdinfo. If the file descriptor was closed, then the struct `v3d_file_priv` and its stats were already freed and we can't update the per-fd stats. Therefore, if the file descriptor was already closed, don't update the per-fd GPU stats, only update the global ones.

Pull drm updates from Dave Airlie: "As part of building up nova-core/nova-drm pieces we've brought in some rust abstractions through this tree, aux bus being the main one, with devres changes also in the driver-core tree. Along with the drm core abstractions and enough nova-core/nova-drm to use them. This is still all stub work under construction, to build the nova driver upstream. The other big NVIDIA related one is nouveau adds support for Hopper/Blackwell GPUs, this required a new GSP firmware update to 570.144, and a bunch of rework in order to support multiple fw interfaces. There is also the introduction of an asahi uapi header file as a precursor to getting the real driver in later, but to unblock userspace mesa packages while the driver is trapped behind rust enablement.
