Don't print the "previous EQ index" value in case of a EQ heartbeat
failure, because it is incremented along with the EQ CI and therefore
redundant.
In addition, as the CPU-CP PI is zeroed when it reaches a value that is
twice the queue size, add a value of the CI with a similar wrap around,
to make it easier to compare the values.

Moreover, some functions use the inner FW version which shuold be only

Finally, some tests are done to deprecated FW version to which LKD

This commit aligns all APIs to a single function that just compares the

The AIC100 secondary bootloader uses the Sahara protocol for two
purposes - loading the runtime firmware images from the host, and
offloading crashdumps to the host. The crashdump functionality is only
invoked when the AIC100 device encounters a crash and dumps are enabled.
Also the collection of the dump is optional - the host can reject
collecting the dump.
The Sahara protocol contains many features and modes including firmware
upload, crashdump download, and client commands. For simplicity,
implement the parts of the protocol needed for loading firmware to the
device.
Fundamentally, the Sahara protocol is an embedded file transfer
protocol. Both sides negotiate a connection through a simple exchange of
hello messages. After handshaking through a hello message, the device
either sends a message requesting images, or a message advertising the
memory dump available for the host. For image transfer, the remote device
issues a read data request that provides an image (by ID), an offset, and
a length. The host has an internal mapping of image IDs to filenames. The
host is expected to access the image and transfer the requested chunk to
the device. The device can issue additional read requests, or signal that
it has consumed enough data from this image with an end of image message.
The host confirms the end of image, and the device can proceed with
another image by starting over with the hello exchange again.
Some images may be optional, and only provided as part of a provisioning
flow. The host is not aware of this information, and thus should report
an error to the device when an image is not available. The device will
evaluate if the image is required or not, and take the appropriate
action.

ivpu_device->context_xa is locked both in kernel thread and IRQ context.
It requires XA_FLAGS_LOCK_IRQ flag to be passed during initialization
otherwise the lock could be acquired from a thread and interrupted by
an IRQ that locks it for the second time causing the deadlock.
This deadlock was reported by lockdep and observed in internal tests.

This will assure that D3->D0 power cycle will be performed before

When debugging functional issues with workload input processing, it is
useful to know if requests are backing up in the fifo, or perhaps
getting stuck elsewhere. To answer the question of how many requests are
in the fifo, implement a "queued" debugfs entry per-dbc that returns the
number of pending requests when read.

Each DMA Bridge Channel (dbc) has a unique configured fifo size which is
specified by the userspace client of that dbc. Since the fifo is
circular, it is useful to know the configured size when debugging
issues.
Add a per-dbc subdirectory in debugfs and in each subdirectory add a
fifo_size entry that will display the size of that dbc's fifo when read.

During the boot process of AIC100, the bootloaders (PBL and SBL) log
messages to device RAM. During SBL, if the host opens the QAIC_LOGGING
channel, SBL will offload the contents of the log buffer to the host,
and stream any new messages that SBL logs.
This log of the boot process can be very useful for an initial triage of
any boot related issues. For example, if SBL rejects one of the runtime
firmware images for a validation failure, SBL will log a reason why.
Add the ability of the driver to open the logging channel, receive the
messages, and store them. Also define a debugfs entry called "bootlog"
by hooking into the DRM debugfs framework. When the bootlog debugfs
entry is read, the current contents of the log that the host is caching
is displayed to the user. The driver will retain the cache until it
detects that the device has rebooted. At that point, the cache will be
freed, and the driver will wait for a new log. With this scheme, the
driver will only have a cache of the log from the current device boot.
Note that if the driver initializes a device and it is already in the
runtime state (QSM), no bootlog will be available through this mechanism
because the driver and SBL have not communicated.

Merge tag 'pm-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates from Rafael Wysocki:
"From the functional perspective, the most significant change here is
the addition of support for Energy Models that can be updated
dynamically at run time.
There is also the addition of LZ4 compression support for hibernation,
the new preferred core support in amd-pstate, new platforms support in
the Intel RAPL driver, new model-specific EPP handling in intel_pstate
and more.
Apart from that, the cpufreq default transition delay is reduced from
10 ms to 2 ms (along with some related adjustments), the system
suspend statistics code undergoes a significant rework and there is a
usual bunch of fixes and code cleanups all over.

- Allow the Energy Model to be updated dynamically (Lukasz Luba)
- Add support for LZ4 compression algorithm to the hibernation image
creation and loading code (Nikhil V)

Wysocki)

Merge v6.8-rc6 into drm-next
Thomas Zimmermann asked to backmerge -rc6 for drm-misc branches,
there's a few same-area-changed conflicts (xe and amdgpu mostly) that
are getting a bit too annoying.
