As Maxime suggested, add a new helper
drm_kunit_display_mode_from_cea_vic(), it can replace the direct call
of drm_display_mode_from_cea_vic(), and it will help solving
the `mode` memory leaks.

The test here creates an sg table, but never maps it, when
we get to drm_gem_shmem_free, the helper tries to unmap and this
causes warnings on some platforms and debug kernels.
This also sets a 64-bit dma mask, as I see an swiotlb warning if I
stick with the default 32-bit one.

Infoframes in KMS is usually handled by a bunch of low-level helpers
that require quite some boilerplate for drivers. This leads to
discrepancies with how drivers generate them, and which are actually
sent.
Now that we have everything needed to generate them in the HDMI
connector state, we can generate them in our common logic so that
drivers can simply reuse what we precomputed.

Most of the HDMI controllers have an upper TMDS character rate limit
they can't exceed. On "embedded"-grade display controllers, it will
typically be lower than what high-grade monitors can provide these days,
so drivers will filter the TMDS character rate based on the controller
capabilities.
To make that easier to handle for drivers, let's provide an optional
hook to be implemented by drivers so they can tell the HDMI controller
helpers if a given TMDS character rate is reachable for them or not.
This will then be useful to figure out the best format and bpc count for
a given mode.

Most HDMI drivers have some code to calculate the TMDS character rate,
usually to adjust an internal clock to match what the mode requires.
Since the TMDS character rates mostly depends on the resolution, whether
we need to repeat pixels or not, the bpc count and the format, we can
now derive it from the HDMI connector state that stores all those infos
and remove the duplication from drivers.

- Add tracking clear page feature.
- Driver should enable the DRM_BUDDY_CLEARED flag if it
successfully clears the blocks in the free path. On the otherhand,
DRM buddy marks each block as cleared.
- Track the available cleared pages size
- If driver requests cleared memory we prefer cleared memory
but fallback to uncleared if we can't find the cleared blocks.
when driver requests uncleared memory we try to use uncleared but
fallback to cleared memory if necessary.
- When a block gets freed we clear it and mark the freed block as cleared,
when there are buddies which are cleared as well we can merge them.
Otherwise, we prefer to keep the blocks as separated.
- Add a function to support defragmentation.

This KUnit next update for Linux 6.9-rc1 consists of:
-- fix to make kunit_bus_type const
-- kunit tool change to Print UML command
-- DRM device creation helpers are now using the new kunit device
creation helpers. This change resulted in DRM helpers switching
from using a platform_device, to a dedicated bus and device type
used by kunit. kunit devices don't set DMA mask and this caused
regression on some drm tests as they can't allocate DMA buffers.
Fix this problem by setting DMA masks on the kunit device during
initialization.
-- KUnit has several macros which accept a log message, which can
contain printf format specifiers. Some of these (the explicit
log macros) already use the __printf() gcc attribute to ensure
the format specifiers are valid, but those which could fail the
test, and hence used __kunit_do_failed_assertion() behind the scenes,
did not.
These include: KUNIT_EXPECT_*_MSG(), KUNIT_ASSERT_*_MSG(), and
KUNIT_FAIL()
A 9 patch series adds the __printf() attribute, and fixes all of
the issues uncovered.

The drm_buddy_test's alloc_contiguous test used a u64 for the page size,
which was then updated to be an 'unsigned long' to avoid 64-bit
multiplication division helpers.
However, the variable is logged by some KUNIT_ASSERT_EQ_MSG() using the
'%d' or '%llu' format specifiers, the former of which is always wrong,
and the latter is no longer correct now that ps is no longer a u64. Fix
these to all use '%lu'.
Also, drm_mm_test calls KUNIT_FAIL() with an empty string as the
message. gcc and clang warns if a printf format string is empty, so
give these some more detailed error messages, which should be more
useful anyway.

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.

Pull drm fixes from Dave Airlie:
"This is the weekly drm fixes. Non-drivers there is a fbdev/sparc fix,
syncobj, ttm and buddy fixes.
On the driver side, ivpu, meson, i915 have a small fix each. Then
amdgpu and xe have a bunch. Nouveau has some minor uapi additions to
give userspace some useful info along with a Kconfig change to allow
the new GSP firmware paths to be used by default on the GPUs it
supports.
Seems about the usual amount for this time of release cycle.

Guenter Roeck reports that commit a64056bb5a ("drm/tests/drm_buddy:
add alloc_contiguous test") causes build failures on 32-bit targets:
"This patch breaks the build on all 32-bit systems since it introduces
an unhandled direct 64-bit divide operation.
ERROR: modpost: "__umoddi3" [drivers/gpu/drm/tests/drm_buddy_test.ko] undefined!
ERROR: modpost: "__moddi3" [drivers/gpu/drm/tests/drm_buddy_test.ko] undefined!"
and the uses of 'u64' are all entirely pointless. Yes, the arguments to
drm_buddy_init() and drm_buddy_alloc_blocks() are in fact of type 'u64',
but none of the values here are remotely relevant, and the compiler will
happily just do the type expansion.
Of course, in a perfect world the compiler would also have just noticed
that all the values in question are tiny, and range analysis would have
shown that doing a 64-bit divide is pointless, but that is admittedly
expecting a fair amount of the compiler.
IOW, we shouldn't write code that the compiler then has to notice is
unnecessarily complicated just to avoid extra work. We do have fairly
high expectations of compilers, but kernel code should be reasonable to
begin with.
It turns out that there are also other issues with this code: the KUnit
assertion messages have incorrect types in the format strings, but
that's a widely spread issue caused by the KUnit infrastructure not
having enabled format string verification. We'll get that sorted out
separately.

Doesn't seem to compile on 32b, presumably due to u64 mod/division.
Simplest is to just switch over to u32 here. Also make print modifiers
consistent with that.
