When the driver needs to abort waiters for interrupts, for cases
such as critical events that occur and driver need to do hard reset,
in such scenario the driver will complete the fence to wake up the
waiting thread, and will set the fence error indication.
The return value of the completion API will be greater than 0
since it will return the timeout, but as this indicates successful
completion, the driver should mark it as aborted.

Protect against concurrency of user requesting to register a timestamp
offset (where the driver fills the timestamp when the command submission
has finished executing) to a specific user interrupt ID. The
protection is basically to allow only one timestamp registration
request to be handled at a time.
This is needed because the user can decide to re-use a timestamp
offset (register an already registered offset, to a different
interrupt ID). This means the request will cause the timestamp node to
move from one interrupt list to another interrupt list. In such
scenario, without proper protection, we could end up adding the same
node twice to the interrupts wait lists.

The preboot used to statically allocate memory for the comms descriptor
on the device memory when driver requested the descriptor information.
Now preboot moved to dynamic memory allocation where it wants to check
the size the driver expects vs. what the f/w expects.
Note there are no backward compatibility issues as older f/w versions
simply ignore this value.

hl_device_status() returns the status of an acquired device.
If a device is going down (following an rmmod cmd),
it should be marked as an unusable/malfunctioning device, and
hence should not be acquired.
However, since this was not the case so far (i.e., a device going
down would inaccurately return 'in reset' status allowing the user
to acquire the device) it introduced a bug where as part of a reset
flow, the driver could not kill processes that have not run yet, and
since those processes aren't blocked from reacquiring a device,
we get eventually a new flow of a driver attempting to kill all
processes in a list that can't be ever really empty.

If hl_device_cond_reset() is called while a reset is already pending but
hasn't started, the reset request will be dropped.
If the flags of the new request are more severe, e.g. a hard reset while
the pending reset is a compute reset, the eventual reset won't be
suitable for the device status.
To prevent such cases, update the pending reset flags with the new
requests flags before the requests are dropped.

When a H/W event is received while a user is registered to events, no
immediate hard reset will happen, and instead the user will be notified
and will have some time to handle it and eventually release the
device, after which the reset will be done.
If a user, as part of the handling and as part of the cleanup steps
towards releasing the device, unregisters from receiving those events,
and at that time an adjacent H/W event is received, it will be assumed
that the user is not registered to events and thus an immediate hard
reset is required.
To prevent such an unwanted immediate reset, modify the driver to
perform it if the user is not registered to events AND we don't already
have a pending reset for a previous H/W event.

We need to wait for the CLOCK_RESOURCE_OWN_ACK bit to be set
after configuring the workpoint. This step ensures that the VPU
microcontroller clock is actively toggling and ready for operation.
Previously, we relied solely on the READY bit in the VPU_STATUS
register, which indicated the completion of the workpoint download.
However, this approach was insufficient, as the READY bit could be set
while the device was still running on a sideband clock until the PLL
locked. To guarantee that the PLL is locked and the device is running on
the main clock source, we now wait for the CLOCK_RESOURCE_OWN_ACK before
proceeding with the remainder of the power-up sequence.

->size field in struct qaic_bo stores user requested buffer size for
allocate path or size of the dmabuf(PRIME). Now for allocate path driver
allocates a BO of size which is PAGE_SIZE aligned, this size is already
stored in base BO structure (struct drm_gem_object).
So difference is ->size of struct qaic_bo stores the raw value coming from
user and ->size in struct drm_gem_object stores the PAGE_SZIE aligned size.
Do not use ->size from struct qaic_bo for any validation or operation
instead use ->size from struct drm_gem_object since we already have
allocated that much memory then why not use it. Only validate if user
is trying to use more then the BO size. This make the driver more flexible.
After this change ->size field of struct qaic_bo becomes redundant. Remove

Reduce the number of error messages per single failure in
ivpu_dev_init() and ivpu_probe().
Most error messages are already printed by functions called
from ivpu_dev_init(). Add missed error prints in ivpu_ipc_init()
and ivpu_mmu_context_init().

Use managed memory allocation for this. That allows us to not keep
track of all the files any more.
v2: keep drm_debugfs_cleanup(), but rename to drm_debugfs_unregister(),
we still need to cleanup the symlink
