0328bb097b accel/ivpu: Fix race condition when unbinding BOs
[ Upstream commit 00812636df ]

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().

a3c1fa8fe7 accel/ivpu: Ensure rpm_runtime_put in case of engine reset/resume fail
[ Upstream commit 9f6c632857 ]

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.

54c49eca38 accel/ivpu: Prevent recovery work from being queued during device removal
commit 69a79ada8e 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

bugs if recovery accessed freed resources.

Rename ivpu_pm_cancel_recovery() to ivpu_pm_disable_recovery() to better
reflect its new behavior.

6420a8d27e accel/ivpu: Trigger device recovery on engine reset/resume failure
[ Upstream commit a47e36dc5d ]

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.

3e3062be7d accel/ivpu: Abort all jobs after command queue unregister
commit 5bbccadaf3 upstream.

With hardware scheduler it is not expected to receive JOB_DONE
notifications from NPU FW for the jobs aborted due to command queue destroy
JSM command.

Remove jobs submitted to unregistered command queue from submitted_jobs_xa
to avoid triggering a TDR in such case.

Add explicit submitted_jobs_lock that protects access to list of submitted
jobs which is now used to find jobs to abort.

Move context abort procedure to separate work queue not to slow down
handling of IPCs or DCT requests in case where job abort takes longer,
especially when destruction of the last job of a specific context results
in context release.

60cb4dfcf7 accel/ivpu: Fix the NPU's DPU frequency calculation
[ Upstream commit 6c2b75404d ]

Fix the frequency returned to the user space by
the DRM_IVPU_PARAM_CORE_CLOCK_RATE GET_PARAM IOCTL.
The kernel driver returned CPU frequency for MTL and bare
PLL frequency for LNL - this was inconsistent and incorrect
for both platforms. With this fix the driver returns maximum
frequency of the NPU data processing unit (DPU) for all HW
generations. This is what user space always expected.

Also do not set CPU frequency in boot params - the firmware
does not use frequency passed from the driver, it was only
used by the early pre-production firmware.
With that we can remove CPU frequency calculation code.

Show NPU frequency in FREQ_CHANGE interrupt when frequency
tracking is enabled.

handling of operations that should not trigger a recovery process.

Expose ivpu_send_receive_internal(), which is now utilized by the D0i3

These functions have been modified to return error codes gracefully,
rather than initiating recovery.

The updated functions are invoked within ivpu_probe() and ivpu_resume(),
ensuring that any errors encountered during these stages result in a proper
teardown or shutdown sequence. The previous approach of triggering recovery
within these functions could lead to a race condition, potentially causing
undefined behavior and kernel crashes due to null pointer dereferences.
