When use LA464(3A5000 pc), LLVM18 and kernel(which not supports lsx/lasx),
it will get a illegal instruction error. LA464 will return LA464 and
LA664 will return a generic when calling getHostCPUName(). Return LA464
name will add all feature(+f,+d,+lsx,+lasx,lvz) by default and generate
vector instruction, generic will add null. Hence we use util_get_cpu_caps
to judge if kernel supports lsx/lasx or not.
Set lsx and lasx by util_get_cpu_caps. Only LLVM 18 on loongarch
supports lsx and lasx completely. LLVM 16 isn't supported and
LLVM 17's LSX support is incomplete.

Our u_hexdump() squeezes 16-byte chunks filled of zeros, where the unix
hexdump squeezes repeated 16-byte chunks. Turns out panfrost/panvk dumps
can be pretty big when when VM dump is requested
(PANVK_DEBUG/PAN_MESA_DEBUG=dump) and memory regions are
filled with repeated non-zero patterns (like a Z16_UNORM buffer cleared
to 1.0, AKA 0xffff).
Avoiding the repetition of such non-zero patterns in dumps significantly
reduces the size of the dumps. It also clears any confusion for people
used to the original hexdump semantics where a star means the previous
line is repeated.

In !25925 I attempted to fix an error spam caused by the disk cache not
creating parent directories of the cache directory when needed,
resulting in failure to create the disk cache. Presumably that is bad
for performance.
Unfortunately I did a really bad job and only fixed the edge case where
the cache dir is given by $MESA_SHADER_CACHE_DIR rather than the general
case. Here I attempt to be more comprehensive.

The `capture_not_overwritten` unit test captures and compares two
backtraces -- one from inside a call to `func_c` and one outside -- and
confirms that they are not identical. That is, that `func_c` is in the
backtrace.
On 32-bit x86, without `-fno-omit-frame-pointer`, the function will not
emit a stack frame. As a result, the unit test fails.
The fix is to compile `func_c` with the flag `-fno-omit-frame-pointer`
to prevent the compiler from optimizing out the stack frame which is
otherwise unneeded.

the CL CTS added a new test being printf("\n", "foo"), but we ended up
printing the new line twice. If we can't find a specifier anymore, ignore
the argument as after the loop processing all arguments we'll print the
remaining format string anyway.

So that the depfile contains a reference to the original source rather
than the copied one. This is necessary to avoid ninja not finding the
copy and causing spurious rebuilds when the copy has been removed, as
well as correctly tracking changes to the input files.

Instead of having a hardcoded table to convert between sRGB formats and
their linear-gamma equivalents (and vice-versa), generate this from the
information in the format table.
This requires adding a 'sublayout' attribute to differentiate between,
e.g. DXT1 and DXT3, which otherwise appear to be equivalent but for
their name prefix.
As an anonymous union is being used, we also need named initialisers for
the util_format_description entries.

u_format has always had its format table in CSV. This is kind of nice
for some things, but is a serious pain to extend, especially with
optional fields.
In going through our many (many, many) duplicated tables of format
mappings, it would've been nice to add some descriptions to our central
u_format table, such as mapping to DRM FourCC, to EGLImage mappings, and
to GL internalformats for EGLImage imports. Unfortunately, doing so with
more additional fields would just make the CSV totally unreadable.
Move the CSV table to a YAML-based table and adjust the Python parsers
to suit. The resulting generated files are identical before and after
the transition.
The new parser also has a significant amount of format validation to
make it easier to catch common errors.

Move it into src/gallium/include/ to make it absolutely clear this is a Mesa detail.
While we're at it, clean up its include sites, including some places
where we can just include kopper_interface.h instead since it includes
mesa_interface.h as its first act.

This removes the unrequired dependance on _mesa_init_debug() and moves
all log code to the util file so that _mesa_log* can now be used without
creating a dependance on mesa/main. Since the code we are moving depends
on the code already in the util (as it was moved here previously) this is
also a much better spot for the code.
