b132ac51d7 accel/ivpu/37xx: Fix missing VPUIP interrupts
Move sequence of masking and unmasking global interrupts from buttress
interrupt handler to generic one that handles both VPUIP and BTRS
interrupts. Unmasking global interrupts will re-trigger MSI for any
pending interrupts.

Lack of this sequence will cause the driver to miss any
VPUIP interrupt that comes after reading VPU_37XX_HOST_SS_ICB_STATUS_0
and before clearing all active interrupt sources.

8f5ad367e8 accel/ivpu: Extend address range for MMU mmap
Allow to use whole address range in MMU context mmap which is up to 48
bits. Return invalid argument from MMU context mmap in case address is
not aligned to MMU page size, address is below MMU page size or address
is greater then 47 bits.

This fixes problem disallowing to run large models on VPU4

610b5d219d Revert "accel/ivpu: Use cached buffers for FW loading"
This reverts commit 645d694559.

The commit cause issues with memory access from the device side.
Switch back to write-combined memory mappings until the issues
will be properly addressed.

Add extra wmb() needed when boot_params->save_restore_ret_address() is
modified.

645d694559 accel/ivpu: Use cached buffers for FW loading
Create buffers with cache coherency on the CPU side (write-back) while
disabling snooping on the VPU side. These buffers require an explicit
cache flush after each CPU-side modification.

Configuring pages as write-combined may introduce significant delays,
potentially taking hundreds of milliseconds for 64 MB buffers.

Added internal DRM_IVPU_BO_NOSNOOP mask which disables snooping on the
VPU side. Allocate FW runtime memory buffer (64 MB) as cached with
snooping-disabled.

This fixes random long FW loading times and boot params memory
corruption on warmboot (due to missed wmb).

ec3e3adc6d accel/ivpu/40xx: Disable frequency change interrupt
Do not enable frequency change interrupt on 40xx as it might
lead to an interrupt storm in current design.

FREQ_CHANGE interrupt is triggered on D0I2 entry which will cause
KMD to check VPU interrupt sources by reading VPUIP registers.
Access to those registers will toggle necessary clocks and trigger
another FREQ_CHANGE interrupt possibly ending in an infinite loop.

FREQ_CHANGE interrupt has only debug purposes and can be permanently
disabled.

6c3f2f90cc accel/ivpu/40xx: Ensure clock resource ownership Ack before Power-Up
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.

in corrupting firmware memory and following FW crash with messages:

4b2fd81f2a accel/ivpu: refactor deprecated strncpy
`strncpy` is deprecated for use on NUL-terminated destination strings [1].

A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on its destination buffer argument which is
_not_ the case for `strncpy`!

Also remove extraneous if-statement as it can never be entered. The
return value from `strncpy` is it's first argument. In this case,
`...dyndbg_cmd` is an array:
| 	char dyndbg_cmd[VPU_DYNDBG_CMD_MAX_LEN];
             ^^^^^^^^^^
This can never be NULL which means `strncpy`'s return value cannot be
NULL here. Just use `strscpy` which is more robust and results in
simpler and less ambiguous code.

Moreover, remove needless `... - 1` as `strscpy`'s implementation
ensures NUL-termination and we do not need to carefully dance around
ending boundaries with a "- 1" anymore.

96d3c1cade accel/qaic: Clean up integer overflow checking in map_user_pages()
The encode_dma() function has some validation on in_trans->size but it
would be more clear to move those checks to find_and_map_user_pages().

The encode_dma() had two checks:

	if (in_trans->addr + in_trans->size < in_trans->addr || !in_trans->size)
		return -EINVAL;

The in_trans->addr variable is the starting address.  The in_trans->size
variable is the total size of the transfer.  The transfer can occur in
parts and the resources->xferred_dma_size tracks how many bytes we have
already transferred.

This patch introduces a new variable "remaining" which represents the
amount we want to transfer (in_trans->size) minus the amount we have
already transferred (resources->xferred_dma_size).

I have modified the check for if in_trans->size is zero to instead check
if in_trans->size is less than resources->xferred_dma_size.  If we have
already transferred more bytes than in_trans->size then there are negative
bytes remaining which doesn't make sense.  If there are zero bytes
remaining to be copied, just return success.

The check in encode_dma() checked that "addr + size" could not overflow
and barring a driver bug that should work, but it's easier to check if
we do this in parts.  First check that "in_trans->addr +
resources->xferred_dma_size" is safe.  Then check that "xfer_start_addr +
remaining" is safe.

My final concern was that we are dealing with u64 values but on 32bit
systems the kmalloc() function will truncate the sizes to 32 bits.  So
I calculated "total = in_trans->size + offset_in_page(xfer_start_addr);"
and returned -EINVAL if it were >= SIZE_MAX.  This will not affect 64bit
systems.

aa5f04d2e5 accel/ivpu: Extend get_param ioctl to identify capabilities
Add DRM_IVPU_PARAM_CAPABILITIES parameters to get_param ioctl to query
driver capabilities. For now use it for identify metric streamer and
new dma memory range features. Currently upstream version of intel_vpu
does not have those, they will be added it the future.

51b56382ed accel/qaic: tighten bounds checking in decode_message()
Copy the bounds checking from encode_message() to decode_message().

This patch addresses the following concerns.  Ensure that there is
enough space for at least one header so that we don't have a negative
size later.

	if (msg_hdr_len < sizeof(*trans_hdr))

Ensure that we have enough space to read the next header from the
msg->data.

	if (msg_len > msg_hdr_len - sizeof(*trans_hdr))
		return -EINVAL;

Check that the trans_hdr->len is not below the minimum size:

	if (hdr_len < sizeof(*trans_hdr))

This minimum check ensures that we don't corrupt memory in
decode_passthrough() when we do.

	memcpy(out_trans->data, in_trans->data, len - sizeof(in_trans->hdr));

And finally, use size_add() to prevent an integer overflow:

	if (size_add(msg_len, hdr_len) > msg_hdr_len)

ea33cb6fc2 accel/qaic: tighten bounds checking in encode_message()
There are several issues in this code.  The check at the start of the
loop:

	if (user_len >= user_msg->len) {

This check does not ensure that we have enough space for the trans_hdr
(8 bytes).  Instead the check needs to be:

	if (user_len > user_msg->len - sizeof(*trans_hdr)) {

That subtraction is done as an unsigned long we want to avoid
negatives.  Add a lower bound to the start of the function.

	if (user_msg->len < sizeof(*trans_hdr))

There is a second integer underflow which can happen if
trans_hdr->len is zero inside the encode_passthrough() function.

	memcpy(out_trans->data, in_trans->data, in_trans->hdr.len - sizeof(in_trans->hdr));

Instead of adding a check to encode_passthrough() it's better to check
in this central place.  Add that check:

	if (trans_hdr->len < sizeof(trans_hdr)

The final concern is that the "user_len + trans_hdr->len" might have an
integer overflow bug.  Use size_add() to prevent that.

-	if (user_len + trans_hdr->len > user_msg->len) {
+	if (size_add(user_len, trans_hdr->len) > user_msg->len) {

Clear all assignments of struct drm_driver's fd/handle callbacks to
drm_gem_prime_fd_to_handle() and drm_gem_prime_handle_to_fd(). These
functions are called by default. Add a TODO item to convert vmwgfx
to the defaults as well.

8d0d16a3ef accel/qaic: Call DRM helper function to destroy prime GEM
smatch warning:
	drivers/accel/qaic/qaic_data.c:620 qaic_free_object() error:
		dereferencing freed memory 'obj->import_attach'

obj->import_attach is detached and freed using dma_buf_detach().
But used after free to decrease the dmabuf ref count using
dma_buf_put().

drm_prime_gem_destroy() handles this issue and performs the proper clean
up instead of open coding it in the driver.
