2026-03-26drm/xe/uapi: Add UAPI support for purgeable buffer objectsHimal Prasad Ghimiray
Extend the DRM_XE_MADVISE ioctl to support purgeable buffer object management by adding DRM_XE_VMA_ATTR_PURGEABLE_STATE attribute type. This allows userspace applications to provide memory usage hints to the kernel for better memory management under pressure: - WILLNEED: Buffer is needed and should not be purged. If the BO was previously purged, retained field returns 0 indicating backing store was lost (once purged, always purged semantics matching i915). - DONTNEED: Buffer is not currently needed and may be purged by the kernel under memory pressure to free resources. Only applies to non-shared BOs. To prevent undefined behavior, the following operations are blocked while a BO is in DONTNEED state: - New mmap() operations return -EBUSY - VM_BIND operations return -EBUSY - New dma-buf exports return -EBUSY - CPU page faults return SIGBUS - GPU page faults fail with -EACCES This ensures applications cannot use a BO while marked as DONTNEED, preventing erratic behavior when the kernel purges the backing store. The implementation includes a 'retained' output field (matching i915's drm_i915_gem_madvise.retained) that indicates whether the BO's backing store still exists (1) or has been purged (0). Added DRM_XE_QUERY_CONFIG_FLAG_HAS_PURGING_SUPPORT flag to allow userspace to detect kernel support for purgeable buffer objects before attempting to use the feature.

Add support for querying per-process buffer object (BO) memory usage through the amdxdna GET_ARRAY UAPI. Introduce a new query type, DRM_AMDXDNA_BO_USAGE, along with struct amdxdna_drm_bo_usage to report BO memory usage statistics, including heap, total, and internal usage. Track BO memory usage on a per-client basis by maintaining counters in GEM open/close and heap allocation/free paths. This ensures the reported statistics reflect the current memory footprint of each process. Wire the new query into the GET_ARRAY implementation to expose the usage information to userspace.

2026-03-20accel/amdxdna: Refactor GEM BO handling and add helper APIs for address ↵Max Zhen
retrieval Refactor amdxdna GEM buffer object (BO) handling to simplify address management and unify BO type semantics. Introduce helper APIs to retrieve commonly used BO addresses: - User virtual address (UVA) - Kernel virtual address (KVA) - Device address (IOVA/PA) These helpers centralize address lookup logic and avoid duplicating BO-specific handling across submission and execution paths. This also improves readability and reduces the risk of inconsistent address handling in future changes. As part of the refactor: - Rename SHMEM BO type to SHARE to better reflect its usage. - Merge CMD BO handling into SHARE, removing special-case logic for command buffers. - Consolidate BO type handling paths to reduce code duplication and simplify maintenance. No functional change is intended. The refactor prepares the driver for future enhancements by providing a cleaner abstraction for BO address management.

2026-03-18drm: Add CRTC background color propertyCristian Ciocaltea
Some display controllers can be hardware programmed to show non-black colors for pixels that are either not covered by any plane or are exposed through transparent regions of higher planes. This feature can help reduce memory bandwidth usage, e.g. in compositors managing a UI with a solid background color while using smaller planes to render the remaining content. To support this capability, introduce the BACKGROUND_COLOR standard DRM mode property, which can be attached to a CRTC through the drm_crtc_attach_background_color_property() helper function. Additionally, define a 64-bit ARGB format value to be built with the help of a couple of dedicated DRM_ARGB64_PREP*() helpers. Individual color components can be extracted with desired precision using the corresponding DRM_ARGB64_GET*() macros.

Add a new VM_BIND flag, DRM_XE_VM_BIND_FLAG_DECOMPRESS, that lets userspace express intent for the driver to perform on-device in-place decompression for the GPU mapping created by a MAP bind operation. This flag is used by subsequent driver changes to trigger scheduling of GPU work that resolves compressed VRAM pages into an uncompressed PAT VM mapping. Behavior and semantics: - Valid only for DRM_XE_VM_BIND_OP_MAP. IOCTLs using this flag on other ops are rejected (-EINVAL). - The bind's pat_index must select the device "no-compression" PAT entry; otherwise the ioctl is rejected (-EINVAL). - Only meaningful for VRAM-backed BOs on devices that support Flat CCS and the required hardware generation (driver will return -EOPNOTSUPP if not). - On success the driver schedules a migrate/resolve and installs the returned dma_fence into the BO's kernel reservation (DMA_RESV_USAGE_KERNEL).

Similar to i915's commit cebc13de7e704b1355bea208a9f9cdb042c74588 ("drm/i915: Whitelist COMMON_SLICE_CHICKEN3 for UMD access"), except that instead of putting the register on the allowlist for UMD to program, the KMD is doing the programming at context initialization based on a queue creation flag. This is a recommended tuning setting for both gen12 and Xe_HP platforms. If a render queue is created with DRM_XE_EXEC_QUEUE_SET_STATE_CACHE_PERF_FIX, COMMON_SLICE_CHICKEN3 will be programmed at initialization to enable the render color cache to key with BTP+BTI (binding table pool + binding table entry) instead of just BTI (binding table entry). This enables the UMD to avoid emitting render-target-cache-flush + stall-at-pixel-scoreboard every time a binding table entry pointing to a render target is changed. v2: Use xe_lrc_write_ring() v3: Update xe_query.c to report availability v4: Rename defines to add DISABLE_ v5: update commit message v6: rebase Mesa MR: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/39982 Bspec: 73993, 73994, 72161, 31870, 68331 Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patch.msgid.link/20260306075504.1288676-1-lionel.g.landwerlin@intel.com

2026-03-05drm/ras: Introduce the DRM RAS infrastructure over generic netlinkRodrigo Vivi
Introduces the DRM RAS infrastructure over generic netlink. The new interface allows drivers to expose RAS nodes and their associated error counters to userspace in a structured and extensible way. Each drm_ras node can register its own set of error counters, which are then discoverable and queryable through netlink operations. This lays the groundwork for reporting and managing hardware error states in a unified manner across different DRM drivers. Currently it only supports error-counter nodes. But it can be extended later. The registration is also not tied to any drm node, so it can be used by accel devices as well. It uses the new and mandatory YAML description format stored in Documentation/netlink/specs/. This forces a single generic netlink family namespace for the entire drm: "drm-ras". But multiple-endpoints are supported within the single family. Any modification to this API needs to be applied to Documentation/netlink/specs/drm_ras.yaml before regenerating the code: $ tools/net/ynl/pyynl/ynl_gen_c.py --spec \ Documentation/netlink/specs/drm_ras.yaml --mode uapi --header \ -o include/uapi/drm/drm_ras.h $ tools/net/ynl/pyynl/ynl_gen_c.py --spec \ Documentation/netlink/specs/drm_ras.yaml --mode kernel \ --header -o drivers/gpu/drm/drm_ras_nl.h $ tools/net/ynl/pyynl/ynl_gen_c.py --spec \ Documentation/netlink/specs/drm_ras.yaml \ --mode kernel --source -o drivers/gpu/drm/drm_ras_nl.c Cc: Zack McKevitt <zachary.mckevitt@oss.qualcomm.com> Cc: Lijo Lazar <lijo.lazar@amd.com> Cc: Hawking Zhang <Hawking.Zhang@amd.com> Cc: Jakub Kicinski <kuba@kernel.org> Cc: David S.

2026-02-24drm/xe/uapi: Introduce a flag to disallow vm overcommit in fault modeThomas Hellström
Some compute applications may try to allocate device memory to probe how much device memory is actually available, assuming that the application will be the only one running on the particular GPU. That strategy fails in fault mode since it allows VM overcommit. While this could be resolved in user-space it's further complicated by cgroups potentially restricting the amount of memory available to the application. Introduce a vm create flag, DRM_XE_VM_CREATE_NO_VM_OVERCOMMIT, that allows fault mode to mimic the behaviour of !fault mode WRT this. It blocks evicting same vm bos during VM_BIND processing. However, it does *not* block evicting same-vm bos during pagefault processing, preferring eviction rather than VM banning in OOM situations.

2026-02-24drm/nouveau: Add DRM_IOCTL_NOUVEAU_GET_ZCULL_INFOMel Henning
Add kernel-side support for using the zcull hardware in nvidia gpus. zcull aims to improve memory bandwidth by using an early approximate depth test, similar to hierarchical Z on an AMD card. Add a new ioctl that exposes zcull information that has been read from the hardware. Userspace uses each of these parameters either in a heuristic for determining zcull region parameters or in the calculation of a buffer size. It appears the hardware hasn't changed its structure for these values since FERMI_C (circa 2011), so the assumption is that it won't change on us too quickly, and is therefore reasonable to include in UAPI. This bypasses the nvif layer and instead accesses nvkm_gr directly, which mirrors existing usage of nvkm_gr_units(). There is no nvif object for nvkm_gr yet, and adding one is not trivial.

2026-01-29drm: add ARM interleaved 64k modifierCaterina Shablia
This modifier is primarily intended to be used by panvk to implement sparse partially-resident images with better map and unmap performance, and no worse access performance, compared to implementing them in terms of U-interleaved. With this modifier, the plane is divided into 64k byte 1:1 or 2:1 -sided tiles. The 64k tiles are laid out linearly. Each 64k tile is divided into blocks of 16x16 texel blocks each, which themselves are laid out linearly within a 64k tile. Then within each such 16x16 block, texel blocks are laid out according to U order, similar to 16X16_BLOCK_U_INTERLEAVED. Unlike 16X16_BLOCK_U_INTERLEAVED, the layout does not depend on whether a format is compressed or not. The hardware features corresponding to this modifier are available starting with v10 (second gen Valhall.) The corresponding panvk MR can be found at: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/38986 Previous version: https://lists.freedesktop.org/archives/dri-devel/2026-January/547072.html No changes since v2 Changes since v1: * Rewrite the description of the modifier to be hopefully unambiguous.

2026-01-10drm/amdgpu: Drop MMIO_REMAP domain bit and keep it InternalChristian König
"AMDGPU_GEM_DOMAIN_MMIO_REMAP" - Never activated as UAPI and it turned out that this was to inflexible. Allocate the MMIO_REMAP buffer object as a regular GEM BO and explicitly move it into the fixed AMDGPU_PL_MMIO_REMAP placement at the TTM level. This avoids relying on GEM domain bits for MMIO_REMAP, keeps the placement purely internal, and makes the lifetime and pinning of the global MMIO_REMAP BO explicit. The BO is pinned in TTM so it cannot be migrated or evicted. The corresponding free path relies on normal DRM teardown ordering, where no further user ioctls can access the global BO once TTM teardown begins. v2 (Srini): - Updated patch title. - Drop use of AMDGPU_GEM_DOMAIN_MMIO_REMAP in amdgpu_ttm.c. The MMIO_REMAP domain bit is removed from UAPI, so keep the MMIO_REMAP BO allocation domain-less (bp.domain = 0) and rely on the TTM placement (AMDGPU_PL_MMIO_REMAP) for backing/pinning. - Keep fdinfo/mem-stats visibility for MMIO_REMAP by classifying BOs based on bo->tbo.resource->mem_type == AMDGPU_PL_MMIO_REMAP, since the domain bit is removed. v3: Squash patches #1 & #3 Fixes: 056132483724 ("drm/amdgpu/uapi: Introduce AMDGPU_GEM_DOMAIN_MMIO_REMAP") Fixes: 2a7a794eb82c ("drm/amdgpu/ttm: Allocate/Free 4K MMIO_REMAP Singleton") Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Cc: Leo Liu <leo.liu@amd.com> Cc: Ruijing Dong <ruijing.dong@amd.com> Cc: David (Ming Qiang) Wu <David.Wu3@amd.com> Signed-off-by: Srinivasan Shanmugam <srinivasan.shanmugam@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
