On MTL, for obvious reasons, HuC is only available on the media tile.
We already disable SW support for HuC on the root gt due to the
absence of VCS engines, but we also need to update the getparam to point
to the HuC struct in the media GT.

The full authentication via the GSC requires an heci packet submission
to the GSC FW via the GSC CS. The GSC has new PXP command for this
(literally called NEW_HUC_AUTH).
The intel_huc_auth function is also updated to handle both authentication
types.

Before we add the second step of the MTL HuC auth (via GSC), we need to
have the ability to differentiate between them. To do so, the huc
authentication check is duplicated for GuC and GSC auth, with
GSC-enabled binaries being considered fully authenticated only after
the GSC auth step.
To report the difference between the 2 auth steps, a new case is added
to the HuC getparam. This way, the clear media driver can start
submitting before full auth, as partial auth is enough for those
workloads.
v2: fix authentication status check for DG2
v3: add a better comment at the top of the HuC file to explain the
different approaches to load and auth (John)
v4: update call to intel_huc_is_authenticated in the pxp code to check

In the previous patch we extracted the offset of the legacy-style HuC
binary located within the GSC-enabled blob, so now we can use that to
load the HuC via DMA if the fuse is set that way.
Note that we now need to differentiate between "GSC-enabled binary" and
"loaded by GSC", so the former case has been renamed to "has GSC headers"
for clarity, while the latter is now based on the fuse instead of the
binary format. This way, all the legacy load paths are automatically
taken (including the auth by GuC) without having to implement further
code changes.

The new binaries that support the 2-step authentication contain the
legacy-style binary, which we can use for loading the HuC via DMA. To
find out where this is located in the image, we need to parse the
manifest of the GSC-enabled HuC binary. The manifest consist of a
partition header followed by entries, one of which contains the offset
we're looking for.
Note that the DG2 GSC binary contains entries with the same names, but
it doesn't contain a full legacy binary, so we need to skip assigning
the dma offset in that case (which we can do by checking the ccs).
Also, since we're now parsing the entries, we can extract the HuC
version that way instead of using hardcoded offsets.
Note that the GSC binary uses the same structures in its binary header,
so they've been added in their own header file.
v2: fix structure names to match meu defines (s/CPT/CPD/), update commit
message, check ccs validity, drop old version location defines.
v3: drop references to the MEU tool to reduce confusion, fix log (John)
v4: fix log for real (John)

Now that each FW has its own reserved area, we can keep them always
pinned and skip the pin/unpin dance on reset. This will make things
easier for the 2-step HuC authentication, which requires the FW to be
pinned in GGTT after the xfer is completed.
Since the vma is now valid for a long time and not just for the quick
pin-load-unpin dance, the name "dummy" is no longer appropriare and has
been replaced with vma_res. All the functions have also been updated to
operate on vma_res for consistency.
Given that we pin the vma behind the allocator's back (which is ok
because we do the pinning in an area that was previously reserved for
thus purpose), we do need to explicitly re-pin on resume because the
automated helper won't cover us.

The warning is pointing out that while 'enum i915_cache_level' and
'unsigned int' are ABI compatible, these indirect calls will fail
clang's kernel Control Flow Integrity (kCFI) checks, as the callback's
signature does not exactly match the prototype's signature.
To fix this, replace the cache_level parameter with pat_index, as was
done in other places within i915 where there is no difference between
cache_level and pat_index on certain generations.

When booting a kernel compiled with CONFIG_CFI_CLANG (kCFI), there is a

versus actual type and failures occur when the two types do not match.

In this case, the pre-gen8 pte_encode functions have a second parameter

For framebuffers in I/O and system memory, add macros that set
struct fb_ops to the respective callback functions.
For deferred I/O, add macros that generate callback functions with
damage handling. Add initializer macros that set struct fb_ops to
the generated callbacks.
These macros can remove a lot boilerplate code from fbdev drivers.
The drivers are supposed to use the macro that is required for its
framebuffer. Each macro is split into smaller helpers, so that
drivers with non-standard callbacks can pick and customize callbacks
as needed. There are individual helper macros for read/write, mmap

Many fbdev drivers use the same set of fb_ops helpers. Add Kconfig
options to select them at once. This will help with making DRM's
fbdev emulation code more modular, but can also be used to simplify

pmu_needs_timer() keeps the timer running even when GT is parked,
ostensibly to sample requested/actual frequencies. However
frequency_sample() has the following:
/* Report 0/0 (actual/requested) frequency while parked. */
if (!intel_gt_pm_get_if_awake(gt))
return;
The above code prevents frequencies to be sampled while the GT is
parked. So we might as well turn off the sampling timer itself in this
case and save CPU cycles/power.
v2: Instead of turning freq bits off, return false, since no counters will
run after this change when GT is parked (Tvrtko)

Clearing out report id and timestamp as means to detect unlanded reports
only works if report size is power of 2. That is, only when report size is
a sub-multiple of the OA buffer size can we be certain that reports will
land at the same place each time in the OA buffer (after rewind). If report
size is not a power of 2, we need to zero out the entire report to be able
to detect unlanded reports reliably.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
panel_edp_remove() always returned zero, so convert it to return void
without any loss and then just drop the return from
panel_edp_platform_remove().

In addition to the already defined REQUEST HXG message format,
which is used when sender expects some confirmation or data,
HXG protocol includes definition of the FAST REQUEST message,
that may be used when sender does not expect any useful data
to be returned.
Using this instead of GUC_HXG_TYPE_EVENT for non-blocking CTB requests
will allow GuC to send back GUC_HXG_TYPE_RESPONSE_FAILURE in case of
errors.
Note that it is not possible to return such errors to the caller,
since this is for non-blocking calls and the related fence is not
stored. Instead such messages are treated as unexpected, which will
give an indication of potential GuC misprogramming that warrants extra
debugging effort.

Allow compute contexts to submit the maximal amount of work without
blocking userspace.
The original size for user LRC ring's (SZ_16K) was chosen to minimise
memory consumption, without being so small as to frequently stall in the
middle of workloads. With the main consumers being GL / media pipelines
of 2 or 3 batches per frame, we want to support ~10 requests in flight
to allow for the application to control throttling without stalling

In the event a device is connected to the samsung-dsim
controller that doesn't support the burst-clock, the
driver is able to get the requested pixel clock from the
attached device or bridge. In these instances, the
samsung,burst-clock-frequency isn't needed, so remove
it from the required list.
The pll-clock frequency can be set by the device tree entry
for samsung,pll-clock-frequency, but in some cases, the
pll-clock may have the same clock rate as sclk_mipi clock.
If they are equal, this flag is not needed since the driver
will use the sclk_mipi rate as a fallback.
