2024-09-24drm: Link drm_rect.o into DRM core moduleThomas Zimmermann
Several places in drm.ko use struct drm_rect and its helpers. This only works as the called interfaces are declared as static inline in the header file.

2024-09-24drm/i915: Set clear color block size to 0x0Ville Syrjälä
We don't use the block size information for the clear color plane. Technically the entire fb is the single block for the single 64B clear color surface, so there is just no way to delcare that as a constant since the fb size can be anything. Define the clear color block size as 0x0 to make things less confusing. We already declared that cpp/chars_per_block=0 for the clear color as well. That also causes the drm core code to mostly ignore the clear color plane, which is exactly what we want since that code doesn't know how to deal with the clear color plane.

2024-09-24drm/i915: Move the dodgy pre-g4x wm stuff into i9xx_wmVille Syrjälä
As with other watermark calculations, the dodgy pre-g4x update_wm_{pre,post} flag calcultion would like to know if a modeset is about to happen or not, and technically later stages in the atomic_check() may still flag one. In practice that shouldn't happen as we don't have dynamic CDCLK implemented for these old platforms.

2024-09-24drm/sched: Fix dynamic job-flow control raceRob Clark
Fixes a race condition reported here: https://github.com/AsahiLinux/linux/issues/309#issuecomment-2238968609 The whole premise of lockless access to a single-producer-single- consumer queue is that there is just a single producer and single consumer. That means we can't call drm_sched_can_queue() (which is about queueing more work to the hw, not to the spsc queue) from anywhere other than the consumer (wq). This call in the producer is just an optimization to avoid scheduling the consuming worker if it cannot yet queue more work to the hw. It is safe to drop this optimization to avoid the race condition.

2024-09-23drm/xe/xe2: Extend performance tuning to media GTGustavo Sousa
With exception of "Tuning: L3 cache - media", we are currently applying recommended performance tuning settings only for the primary GT. Let's also implement them for the media GT when applicable. According to our spec, media GT registers CCCHKNREG1 and L3SQCREG* exist only in Xe2_LPM and their offsets do not match their primary GT counterparts. Furthermore, the range where CCCHKNREG1 belongs is not listed as a multicast range on the media GT. As such, we need to have Xe2_LPM-specific definitions for those registers and apply the setting only for that specific IP. Both Xe2_HPM and Xe2_LPM contain STATELESS_COMPRESSION_CTRL and the offset on the media GT matches the one on the primary one. So we can simply have a copy of "Tuning: Stateless compression control" for the media GT. v2: - Fix implementation with respect to multicast vs non-multicast registers. (Matt) - Add missing XE2LPM_CCCHKNREG1 on second action of "Tuning: Compression Overfetch - media". v3: - STATELESS_COMPRESSION_CTRL on Xe2_HPM is also a multicast register, do not define a XE2HPM_STATELESS_COMPRESSION_CTRL register.

XArray provides it's own internal lock which protects the internal array when entries are being simultaneously added and removed. However there is still a race between retrieving the pointer from the XArray and incrementing the reference count. To avoid this race simply hold the internal XArray lock when incrementing the reference count, this ensures there cannot be a racing call to xa_erase().

2024-09-23drm/i915/pps: split intel_pps_reset_all() to vlv and bxt variantsJani Nikula
The intel_pps_reset_all() function does similar but not quite the same things for VLV/CHV and BXT/GLK. Observe that it's called from platform specific code only, and a split to two functions vlv_pps_reset_all() and bxt_pps_reset_all() is natural. Remove the platform checks and warnings from the functions. We don't usually have them, unless we're unsure. To make this easier to reason about for BXT/GLK, change the condition on caller side from "!PCH" to "BXT || GLK".

An optimization which permits us to avoid writing/reading zero-filled zswap pages to backing store. - "Avoid MAP_FIXED gap exposure" from Liam Howlett. Fixes a race window which occurs when a MAP_FIXED operqtion is occurring during an unrelated vma tree walk. - "mm: remove vma_merge()" from Lorenzo Stoakes. Major rotorooting of the vma_merge() functionality, making ot cleaner, more testable and better tested. - "misc fixups for DAMON {self,kunit} tests" from SeongJae Park. Minor fixups of DAMON selftests and kunit tests. - "mm: memory_hotplug: improve do_migrate_range()" from Kefeng Wang. Code cleanups and folio conversions. - "Shmem mTHP controls and stats improvements" from Ryan Roberts. Cleanups for shmem controls and stats. - "mm: count the number of anonymous THPs per size" from Barry Song. Expose additional anon THP stats to userspace for improved tuning. - "mm: finish isolate/putback_lru_page()" from Kefeng Wang: more folio conversions and removal of now-unused page-based APIs. - "replace per-quota region priorities histogram buffer with per-context one" from SeongJae Park. DAMON histogram rationalization. - "Docs/damon: update GitHub repo URLs and maintainer-profile" from SeongJae Park. DAMON documentation updates. - "mm/vdpa: correct misuse of non-direct-reclaim __GFP_NOFAIL and improve related doc and warn" from Jason Wang: fixes usage of page allocator __GFP_NOFAIL and GFP_ATOMIC flags. - "mm: split underused THPs" from Yu Zhao. Improve THP=always policy. This was overprovisioning THPs in sparsely accessed memory areas. - "zram: introduce custom comp backends API" frm Sergey Senozhatsky. Add support for zram run-time compression algorithm tuning. - "mm: Care about shadow stack guard gap when getting an unmapped area" from Mark Brown. Fix up the various arch_get_unmapped_area() implementations to better respect guard areas. - "Improve mem_cgroup_iter()" from Kinsey Ho. Improve the reliability of mem_cgroup_iter() and various code cleanups. - "mm: Support huge pfnmaps" from Peter Xu. Extends the usage of huge pfnmap support. - "resource: Fix region_intersects() vs add_memory_driver_managed()" from Huang Ying. Fix a bug in region_intersects() for systems with CXL memory. - "mm: hwpoison: two more poison recovery" from Kefeng Wang. Teaches a couple more code paths to correctly recover from the encountering of poisoned memry. - "mm: enable large folios swap-in support" from Barry Song. Support the swapin of mTHP memory into appropriately-sized folios, rather than into single-page folios" * tag 'mm-stable-2024-09-20-02-31' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (416 commits) zram: free secondary algorithms names uprobes: turn xol_area->pages[2] into xol_area->page uprobes: introduce the global struct vm_special_mapping xol_mapping Revert "uprobes: use vm_special_mapping close() functionality" mm: support large folios swap-in for sync io devices mm: add nr argument in mem_cgroup_swapin_uncharge_swap() helper to support large folios mm: fix swap_read_folio_zeromap() for large folios with partial zeromap mm/debug_vm_pgtable: Use pxdp_get() for accessing page table entries set_memory: add __must_check to generic stubs mm/vma: return the exact errno in vms_gather_munmap_vmas() memcg: cleanup with !CONFIG_MEMCG_V1 mm/show_mem.c: report alloc tags in human readable units mm: support poison recovery from copy_present_page() mm: support poison recovery from do_cow_fault() resource, kunit: add test case for region_intersects() resource: make alloc_free_mem_region() works for iomem_resource mm: z3fold: deprecate CONFIG_Z3FOLD vfio/pci: implement huge_fault support mm/arm64: support large pfn mappings mm/x86: support large pfn mappings ...
2024-09-19drm/xe: Use helper for ASID -> VM in GPU faults and access countersMatthew Brost
Normalize both code paths with a helper. Fixes a possible leak access counter path too.

2024-09-19drm/rockchip: Load crtc devices in preferred orderJonas Karlman
On RK3399 the VOPL is loaded before VOPB and get registered as crtc-0. However, on RK3288 and PX30 VOPB is gets registered as crtc-0 instead of VOPL. With VOPL registered as crtc-0 the kernel kms client is not able to enable 4K display modes for console use on RK3399. Load VOPB before VOPL to help kernel kms client make use of 4K display modes for console use on RK3399.
