[Description]
- Add logging for first DMUB inbox message that timed out to diagnostic
data
- It is useful to track the first failed message for debug purposes
because once DMUB becomes hung (typically on a message), it will
remain hung and all subsequent messages. In these cases we're
interested in knowing which is the first message that failed.

- Fix unselectable choice entry in MIPS Kconfig, and forbid this
structure
- Remove unused include/asm-generic/export.h
- Fix a NULL pointer dereference bug in modpost
- Enable -Woverride-init warning consistently with W=1
- Drop KCSAN flags from *.mod.c files
* tag 'kbuild-fixes-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:
kconfig: Fix typo HEIGTH to HEIGHT
Documentation/llvm: Note s390 LLVM=1 support with LLVM 18.1.0 and newer
kbuild: Disable KCSAN for autogenerated *.mod.c intermediaries
kbuild: make -Woverride-init warnings more consistent
modpost: do not make find_tosym() return NULL
export.h: remove include/asm-generic/export.h
kconfig: do not reparent the menu inside a choice block
MIPS: move unselectable FIT_IMAGE_FDT_EPM5 out of the "System type" choice
cxl: remove CONFIG_CXL_PMU entry in drivers/cxl/Kconfig
The -Woverride-init warn about code that may be intentional or not,
but the inintentional ones tend to be real bugs, so there is a bit of
disagreement on whether this warning option should be enabled by default
and we have multiple settings in scripts/Makefile.extrawarn as well as
individual subsystems.
Older versions of clang only supported -Wno-initializer-overrides with
the same meaning as gcc's -Woverride-init, though all supported versions
now work with both. Because of this difference, an earlier cleanup of
mine accidentally turned the clang warning off for W=1 builds and only
left it on for W=2, while it's still enabled for gcc with W=1.
There is also one driver that only turns the warning off for newer
versions of gcc but not other compilers, and some but not all the
Makefiles still use a cc-disable-warning conditional that is no
longer needed with supported compilers here.
Address all of the above by removing the special cases for clang
and always turning the warning off unconditionally where it got
in the way, using the syntax that is supported by both compilers.

be nonseamless. Phantom OTG master pipe reuses the secondary OPP head
pipe. There is no possible seamless path to transit to the new

phantom OTG master pipe. This way we are able to first transit the
minimal transtion state of new and then transit to new state seamlessly.

During minimal transition commit, the base state could be freed if it is current state.
This is because after committing minimal transition state, the current state will be
swapped to the minimal transition state and the old current state will be released.
the release could cause the old current state's memory to be freed. However dc
will derefernce this memory when release minimal transition state. Therefore, we
need to retain the old current state until we release minimal transition state.

[Why]
Cursor updates can be preempted by queued flips in some DMs.
The synchronization model causes this to occur within the same thread
at an intermediate level when we insert logs into the OS queue.
Since this occurs on the same thread and we're still holding the lock
(recursively) the cache is coherent.
The exit sequence will run twice since we technically haven't finished
the exit the first time, so we need a way to detect and avoid the
reallow in the middle of this call to prevent the hang on the cursor
update that was preempted.
[How]
Keep a counter that tracks the depth of the exit calls. Do not reallow
until the counter is zero.

[Why]
Cursor update can be pre-empted by a request for setting target flip
submission.
This causes an issue where we're in the middle of the exit sequence
trying to log to DM, but the pre-emption starts another DMCUB
command submission that requires being out of idle.
The DC lock aqusition can fail, and depending on the DM/OS interface
it's possible that the function inserted into this thread must not fail.
This means that lock aqusition must be skipped and exit *must* occur.
[How]
Modify when we consider idle as active. Consider it exited only once
the exit has fully finished.
Consider it as entered prior to actual notification.
Since we're on the same core/thread the cached values are coherent
and we'll see that we still need to exit. Once the cursor update resumes
it'll continue doing the double exit but this won't cause a functional
issue, just a (potential) redundant operation.

[WHY & HOW]
Since the backup and restore for plane and stream states has
a significant amount of data to copy, we will change the backup
and restore sequence to only take place during full updates.
We will also move the scratch memory to struct dc instead of dc_state
to avoid needing to allocate large amounts of memory every time
we create a new DC state.

[WHY & HOW]
Update planes and stream version 3 separates FULL and FAST updates
to their own sequences. It aims to clean up frequent checks for
update type resulting unnecessary branching in logic flow. It also
adds a new commit minimal transition sequence, which detects the need
for minimal transition based on the actual comparison of current and
new states instead of "predicting" it based on per feature software
policy, i.e. could_mpcc_tree_change_for_active_pipes.
The new commit minimal transition sequence is made universal to any
power saving features that would use extra free pipes such as Dynamic
ODM/MPC Combine, MPO or SubVp. Therefore there is no longer a need to
specially handle compatibility problems with transitions among those
features as they are now transparent to the new sequence.

Fixes index out of bounds issue in the color transformation function.
The issue could occur when the index 'i' exceeds the number of transfer
function points (TRANSFER_FUNC_POINTS).
The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds, an error message is
logged and the function returns false to indicate an error.

[WHY]
Currently 3-tap chroma subsampling is used for YCbCr422/420. When ODM
pipesplit is used, pixels on the left edge of ODM slices need one extra
pixel from the right edge of the previous slice to calculate the correct
chroma value.
Without this change, the chroma value is slightly different than
expected. This is usually imperceptible visually, but it impacts test
pattern CRCs for compliance test automation.
[HOW]
Update logic to use the register for adding extra left edge pixel for
YCbCr422/420 ODM cases.

- Update odm config before calling program pipes for pipe with planes.
The commit also updates blank pattern programming when odm is changed
without plane. This is because number of OPP is changed when ODM
combine is changed. Blank pattern is per OPP so we will need to
reprogram OPP based on the new pipe topology.

Adds a check in the map_hw_resources function to prevent a potential

could potentially be greater than the size of the arrays, leading to a
buffer overflow.
Adds a check to ensure that the index is within the bounds of the
arrays. If the index is out of bounds, an error message is printed and
break it will continue execution with just ignoring extra data early to
prevent the buffer overflow.

[why]
The feature was disabled due to regression found during testing. Now
that all the pending issues are addressed, we are reenabling the power
saving feature again.
The feature optimizes dispclk level when user is using MPO capable
broswers or watching MPO capable videos in windowed mode. The feature
achieves power optimization by utilizing free pipes to process incoming
pixels in parallel. So it reduces max dispclk requirements for each
pipe.
Previously ODM power optimization will be disabled when MPO plane is
present due to technical challeges. This is mainly because ODM divides
pixel workload with respect to stream but MPO plane position and size
are arbitrary with respect to stream. The pixel processing workload of
an MPO plane is not guarenteed to be evenly distributed across DCN pipes.
For example if a plane is moved inside single ODM slice, all the
processing for the plane is distributed to the pipe in the current ODM
slice, while the other ODM slices don't need to process this plane. If
the plane is then moved to the middle crosing two ODM slices, each ODM
slice gets half of the workload. This is especially difficult when the
plane itself has a large source rect which can't be processed by single
DCN pipe. In this case we can't enable ODM power optimization when the
plane is only within one ODM slice.
[how]
To overcome the challeges, new pipe resource management is in place to
make sure a plane is validated with ODM power optimization support if
it can be validated regardless of its position and the same pipe
topology can be used regardless of the plane's position. When the plane
is moved outside current ODM slice, we will set recout to 0 so the pipe
can be idling without the need to update pipe topology. When the user
resizes a plane, it may result in downscaling ratio changes. When the
downscaling ratio is above single pipe's threshold, we will seamlessly
exit ODM power optimization and applies MPC combine to support the plane.
when downscaling ratio becomes smaller, we will seamlessly enter ODM
power optimization again. All these pipe transitions happen
automatically and quietly when the conditions are met without any visual
impacts to the user.

In the first if statement, we're checking if 'replay' is NULL. But in
the second if statement, we're not checking if 'replay' is NULL again
before calling replay->funcs->replay_set_power_opt().
if (replay == NULL && force_static)
return false;
...
if (link->replay_settings.replay_feature_enabled &&
replay->funcs->replay_set_power_opt) {
replay->funcs->replay_set_power_opt(replay, *power_opts, panel_inst);
link->replay_settings.replay_power_opt_active = *power_opts;
}
If 'replay' is NULL, this will cause a null pointer dereference.

The dcn30_get_gamcor_current() function is responsible for determining
the current gamma correction mode used by the display controller.
However, the 'mode' variable, which stores the gamma correction mode,
was not initialized before its first usage, leading to an uninitialized
symbol error.
Thus initializes the 'mode' variable with a default value of LUT_BYPASS
before the conditional statements in the function, improves code clarity
and stability, ensuring correct behavior of the
dcn30_get_gamcor_current() function in determining the gamma correction
mode.
Fixes the below:

when 'find_dcfclk_for_voltage()' function is looping over
VG_NUM_SOC_VOLTAGE_LEVELS (which is 8), but the size of the DcfClocks
array is VG_NUM_DCFCLK_DPM_LEVELS (which is 7).
When the loop variable i reaches 7, the function tries to access
clock_table->DcfClocks[7]. However, since the size of the DcfClocks
array is 7, the valid indices are 0 to 6. Index 7 is beyond the size of
the array, leading to a buffer overflow.
