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.

397f3a7402 accel/ivpu: Add debugfs interface for setting HWS priority bands 
[ Upstream commit 320323d2e5 ]

Add debugfs interface to modify following priority bands properties:
 * grace period
 * process grace period
 * process quantum

This allows for the adjustment of hardware scheduling algorithm parameters
for each existing priority band, facilitating validation and fine-tuning.

 - ivpu_bo_print_info() where we read the shmem->pages without

079d2622f8 accel/ivpu: Fix locking order in ivpu_job_submit 
commit ab680dc6c7 upstream.

Fix deadlock in job submission and abort handling.
When a thread aborts currently executing jobs due to a fault,
it first locks the global lock protecting submitted_jobs (#1).

After the last job is destroyed, it proceeds to release the related context
and locks file_priv (#2). Meanwhile, in the job submission thread,
the file_priv lock (#2) is taken first, and then the submitted_jobs
lock (#1) is obtained when a job is added to the submitted jobs list.

       CPU0                            CPU1
       ----                    	       ----
  (for example due to a fault)         (jobs submissions keep coming)

  lock(&vdev->submitted_jobs_lock) #1
  ivpu_jobs_abort_all()
  job_destroy()
                                      lock(&file_priv->lock)           #2
                                      lock(&vdev->submitted_jobs_lock) #1
  file_priv_release()
  lock(&vdev->context_list_lock)
  lock(&file_priv->lock)           #2

This order of locking causes a deadlock. To resolve this issue,
change the order of locking in ivpu_job_submit().

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.

1be40f79d3 accel/qaic: Fix possible data corruption in BOs > 2G 
[ Upstream commit 84a833d906 ]

When slicing a BO, we need to iterate through the BO's sgt to find the
right pieces to construct the slice. Some of the data types chosen for
this process are incorrectly too small, and can overflow. This can
result in the incorrect slice construction, which can lead to data
corruption in workload execution.

The device can only handle 32-bit sized transfers, and the scatterlist
struct only supports 32-bit buffer sizes, so our upper limit for an
individual transfer is an unsigned int. Using an int is incorrect due to
the reservation of the sign bit. Upgrade the length of a scatterlist
entry and the offsets into a scatterlist entry to unsigned int for a
correct representation.

While each transfer may be limited to 32-bits, the overall BO may exceed
that size. For counting the total length of the BO, we need a type that
can represent the largest allocation possible on the system. That is the
definition of size_t, so use it.

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.

58b5618ba8 accel/ivpu: Add missing MODULE_FIRMWARE metadata 
Modules that load firmware from various paths at runtime must declare
those paths at compile time, via the MODULE_FIRMWARE macro, so that the
firmware paths are included in the module's metadata.

The accel/ivpu driver loads firmware but lacks this metadata,
preventing dracut from correctly locating firmware files. Fix it.

Fixes: 9ab43e95f9 ("accel/ivpu: Switch to generation based FW names")
Fixes: 02d5b0aacd ("accel/ivpu: Implement firmware parsing and booting")
