accel/ivpu: Fix race condition when unbinding BOs

2026-01-30T09:28:48+00:00

[ Upstream commit 00812636df370bedf4e44a0c81b86ea96bca8628 ] Fix 'Memory manager not clean during takedown' warning that occurs when ivpu_gem_bo_free() removes the BO from the BOs list before it gets unmapped. Then file_priv_unbind() triggers a warning in drm_mm_takedown() during context teardown. Protect the unmapping sequence with bo_list_lock to ensure the BO is always fully unmapped when removed from the list. This ensures the BO is either fully unmapped at context teardown time or present on the list and unmapped by file_priv_unbind().

accel/ivpu: Ensure rpm_runtime_put in case of engine reset/resume fail

[ Upstream commit 9f6c63285737b141ca25a619add80a96111b8b96 ] Previously, aborting work could return early after engine reset or resume failure, skipping the necessary runtime_put cleanup leaving the device with incorrect reference count breaking runtime power management state. Replace early returns with goto statements to ensure runtime_put is always executed.

accel/ivpu: Prevent recovery work from being queued during device removal

2025-09-09T16:58:14+00:00

commit 69a79ada8eb034ce016b5b78fb7d08d8687223de upstream. Use disable_work_sync() instead of cancel_work_sync() in ivpu_dev_fini() to ensure that no new recovery work items can be queued after device removal has started. Previously, recovery work could be scheduled even after canceling existing work, potentially leading to use-after-free bugs if recovery accessed freed resources. Rename ivpu_pm_cancel_recovery() to ivpu_pm_disable_recovery() to better reflect its new behavior.

accel/ivpu: Fix reset_engine debugfs file logic

2025-08-15T10:14:10+00:00

commit 541a137254c71822e7a3ebdf8309c5a37b7de465 upstream. The current reset_engine implementation unconditionally resets all engines. Improve implementation to reset only the engine requested by the user space to allow more granular testing. Also use DEFINE_DEBUGFS_ATTRIBUTE() to simplify implementation. Same changes applied to resume_engine debugfs file for consistency.

accel/ivpu: Trigger device recovery on engine reset/resume failure

2025-07-06T09:01:38+00:00

[ Upstream commit a47e36dc5d90dc664cac87304c17d50f1595d634 ] Trigger full device recovery when the driver fails to restore device state via engine reset and resume operations. This is necessary because, even if submissions from a faulty context are blocked, the NPU may still process previously submitted faulty jobs if the engine reset fails to abort them. Such jobs can continue to generate faults and occupy device resources. When engine reset is ineffective, the only way to recover is to perform a full device recovery.
