2025-05-14drm/amdgpu: Fix circular locking in userq creationJesse.Zhang1-3/+2
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>

The ttm_bo_pin and ttm_bo_unpin warnings are resolved by moving the doorbell bo reserve up before pin/unpin.

2025-05-13drm/amdgpu: Fix user queue deadlock by reordering mutex lockingJesse.Zhang1-2/+3
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.

Switch cancel_delayed_work() to cancel_delayed_work_sync() to ensure the delayed work has finished executing before proceeding with resource cleanup.
