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. Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe, and msm being the main ones, and some changes to vsprintf. new drivers: - bring in the asahi uapi header standalone - nova-drm: stub driver rust dependencies (for nova-core): -

2025-05-16gpu: Switch to irq_domain_create_linear()Jiri Slaby (SUSE)
irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2025-05-16drm/amdgpu: fix use-after-unlock in eviction fence destroyArvind Yadav
The eviction fence destroy path incorrectly calls dma_fence_put() on evf_mgr->ev_fence after releasing the ev_fence_lock. This introduces a potential use-after-unlock or race because another thread concurrently modifies evf_mgr->ev_fence. Fix this by grabbing a local reference to evf_mgr->ev_fence under the lock and using that for dma_fence_put() after waiting.

2025-05-14drm/amdgpu: Fix circular locking in userq creationJesse.Zhang
A circular locking dependency was detected between the global `adev->userq_mutex` and per-file `userq_mgr->userq_mutex` when creating user queues. The issue occurs because: 1. `amdgpu_userq_suspend()` and `amdgpu_userq_resume` take `adev->userq_mutex` first, then `userq_mgr->userq_mutex` 2. While `amdgpu_userq_create()` takes them in reverse order This patch resolves the issue by: 1. Moving the `adev->userq_mutex` lock earlier in `amdgpu_userq_create()` to cover the `amdgpu_userq_ensure_ev_fence()` call 2. Releasing it after we're done with both queue creation and the scheduling halt check v2: remove unused adev->userq_mutex lock (Prike) Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Reviewed-by: Prike Liang <Prike.Liang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-05-13drm/amdgpu: Add GFX 9.5.0 support for per-queue/pipe resetJesse.Zhang
This patch enables per-queue and per-pipe reset functionality for GFX IP v9.5.0 when using MEC firmware version 21 (0x15) or later. This change: 1. Refactors the pipe reset support check in gfx_v9_4_3_pipe_reset_support() to use the compute_supported_reset flags instead of hardcoding version checks. 2. Adds support for GFX9.5.0 (IP 9.5.0) with MEC firmware version >= 21 to enable per-queue and per-pipe reset capabilities. v2: Replaced mec version check with !!(adev->gfx.compute_supported_reset & AMDGPU_RESET_TYPE_PER_PIPE) (Lijo) Signed-off-by: Asad Kamal <asad.kamal@amd.com> Signed-off-by: Jesse Zhang <jesse.zhang@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-05-13drm/amdgpu: Fix user queue deadlock by reordering mutex lockingJesse.Zhang
This resolves a deadlock between user queue management and GPU reset paths by enforcing consistent lock ordering. The deadlock occurred when: 1. Process exit path (amdgpu_userq_mgr_fini) would: - Take uqm->userq_mutex - Then try to take adev->userq_mutex for list operations 2. GPU reset path (amdgpu_userq_pre_reset) would: - Take adev->userq_mutex first (for list traversal) - Then take uqm->userq_mutex The solution establishes a strict top-down locking order: 1. Always take adev->userq_mutex before any uqm->userq_mutex 2. Maintain this order consistently across all code paths Changes made: - Reordered locking in amdgpu_userq_mgr_fini() to take device lock first - Kept existing proper order in amdgpu_userq_pre_reset() - Simplified the fini flow by removing redundant operations This prevents circular dependencies while maintaining thread safety during both normal operation and GPU reset scenarios.
