Here is the big set of driver core updates for 6.15-rc1. Lots of stuff
happened this development cycle, including:
- kernfs scaling changes to make it even faster thanks to rcu
- bin_attribute constify work in many subsystems
- faux bus minor tweaks for the rust bindings
- rust binding updates for driver core, pci, and platform busses,
making more functionaliy available to rust drivers. These are all
due to people actually trying to use the bindings that were in 6.14.
- make Rafael and Danilo full co-maintainers of the driver core
codebase
- other minor fixes and updates.
This has been in linux-next for a while now, with the only reported
issue being some merge conflicts with the rust tree. Depending on which
tree you pull first, you will have conflicts in one of them. The merge
resolution has been in linux-next as an example of what to do, or can be
found here:

Prevent runtime resume/suspend while MS IOCTLs are in progress.
Failed suspend will call ivpu_ms_cleanup() that would try to acquire
file_priv->ms_lock, which is already held by the IOCTLs.

Fix deadlock in ivpu_ms_cleanup() by preventing runtime resume after
file_priv->ms_lock is acquired.
During a failure in runtime resume, a cold boot is executed, which
calls ivpu_ms_cleanup_all(). This function calls ivpu_ms_cleanup()
that acquires file_priv->ms_lock and causes the deadlock.

Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

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.

Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
There is a timeout failure been found during stress tests. If the firmware
generates a mailbox response right after driver clears the mailbox channel
interrupt register, the hardware will not generate an interrupt for the
response. This causes the unexpected mailbox command timeout.
To handle this failure, driver checks the interrupt register before
exiting mailbox_rx_worker(). If there is a new response, driver goes back
to process it.

It is required by firmware to wait up to 2 seconds for pending commands
before sending the destroy hardware context command. After 2 seconds
wait, if there are still pending commands, driver needs to cancel them.
So the context destroy steps need to be:
1. Stop drm scheduler. (drm_sched_entity_destroy)
2. Wait up to 2 seconds for pending commands.
3. Destroy hardware context and cancel the rest pending requests.
4. Wait all jobs associated with the hwctx are freed.

Introduces the capability to simulate hardware faults for testing
purposes. The new `fail_hw` fault can be injected in
`ivpu_hw_reg_poll_fld()`, which is used in various parts of the driver
to wait for the hardware to reach a specific state. This allows to test
failures during NPU boot and shutdown, IPC message handling and more.
Fault injection can be enabled using debugfs or a module parameter.

Disable runtime PM for the duration of reset/recovery so it is possible
to set the correct runtime PM state depending on the outcome of the
`ivpu_resume()`. Don’t suspend or reset the HW if the NPU is suspended
when the reset/recovery is requested. Also, move common reset/recovery
code to separate functions for better code readability.

pm_runtime_resume_and_get() sets dev->power.runtime_error that causes
all subsequent pm_runtime_get_sync() calls to fail.
Clear the runtime_error using pm_runtime_set_suspended(), so the driver
doesn't have to be reloaded to recover when the NPU fails to boot during
runtime resume.

Add basic support for the new AIC200 product. The PCIe Device ID is
0xa110. With this, we can turn on the lights for AIC200 by leveraging
much of the existing driver.

As the number of cards supported by the driver grows, their
configurations will differ. The driver needs to become more dynamic
to support these configurations. Currently, each card may differ in
the exposed BARs, the regions they map to, and the family.
Create config structs for each card, and let the driver configure the
qaic_device struct based on the configurations passed to the driver.

During the initialization of the qaic device, pci_select_bars() is
used to fetch a bitmask of the BARs exposed by the device. On devices
that have Virtual Functions capabilities, the bitmask includes SR-IOV
BARs.
Use a mask to filter out SR-IOV BARs if they exist.

AIC200 device will support MSI-X while AIC100 devices will keep using

Devices use 1 MSI vector for the MHI controller and as many vectors as
the DMA bridge channels on the device. During the probing of the
device, the driver allocates 32 MSI vectors, which is usually more
than what is needed for AIC100 devices, which is wasting resources.
Allocate only the needed number of MSI vectors per device.

aic100_image_table is currently defined as a "const char *" array,
this can potentially lead to the accidental modification of the
pointers inside. Also, checkpatch.pl gives a warning about it.
Change the type to a "const char * const" array to make the pointers
immutable, preventing accidental modification of the images' paths.
