accel/ivpu: Trigger recovery on TDR with OS scheduling

2026-04-02T19:29:01Z

With OS scheduling mode the driver cannot determine which context caused the timeout, so context abort cannot be used. Instead of queuing context_abort_work, directly trigger full device recovery when a job timeout (TDR) occurs in OS scheduling mode.

accel/ivpu: Add disable clock relinquish workaround for NVL-A0

Turn on disable clock relinquish workaround for Nova Lake A0. Without this workaround NPU may not power off correctly after inference, leading to unexpected system behavior.

accel/ivpu: Perform engine reset instead of device recovery on TDR

2026-03-20T07:03:11Z

Replace full device recovery on TDR timeout with per-context abort, allowing individual context handling instead of resetting the entire device. Extend ivpu_jsm_reset_engine() to return the list of contexts impacted by the engine reset and use that information to abort only the affected contexts. Only check for potentially faulty contexts when the engine reset was not triggered by an MMU fault or a job completion error status. This prevents misidentifying non-guilty contexts that happened to be running at the time of the fault. Trigger full device recovery if no contexts were marked by engine reset if triggered by job completion timeout, as there is no way to identify guilty one. Add engine reset counter to debugfs for engine resets bookkeeping for debugging/testing purposes.

accel/ivpu: Remove boot params address setting via MMIO register

The NPU 60XX uses the default boot params location specified in the firmware image header, consistent with earlier generations. Remove the unnecessary MMIO register write, freeing the AON register for future use.

accel/ivpu: Limit number of maximum contexts and doorbells per user

2026-03-03T11:54:03Z

Implement per-user resource limits to prevent resource exhaustion. Root users can allocate all available contexts (128) and doorbells (255), while non-root users are limited to half of the available resources (64 contexts and 127 doorbells respectively). This prevents scenarios where a single user could monopolize NPU resources and starve other users on multi-user systems. Change doorbell ID and command queue ID allocation errors to debug messages as those are user triggered.
