The old calculation depended on the sample count, and gave subpar
results for 8x MSAA with standard sample locations. The new calculation
is based on the Intel pass, with some changing of the constants so that
the sample count is always proportional to alpha for 2xMSAA and 4xMSAA
and the addition of rotating the sample mask based on the pixel.

GLSL defines gl_SampleMaskIn as :
"a fragment language that indicates the set of samples covered
by the primitive generating the fragment during multisample
rasterization"
when variable rate shading is enabled, a single invocation might cover
multiple samples. The lowering done in nir_lower_single_sampled() does
not account for that case, so add an option to selectively disable it.

We add a bunch of new helpers to avoid the need to touch >parent_instr,
including the full set of:
* nir_def_is_*
* nir_def_as_*_or_null
* nir_def_as_* [assumes the right instr type]
* nir_src_is_*
* nir_src_as_*
* nir_scalar_is_*
* nir_scalar_as_*
Plus nir_def_instr() where there's no more suitable helper.
Also an existing helper is renamed to unify all the names, while we're
churning the tree:
* nir_src_as_alu_instr -> nir_src_as_alu
..and then we port the tree to use the helpers as much as possible, using
nir_def_instr() where that does not work.

The standard way to query options in mesa is `os_get_option()` which
abstracts platform-specific mechanisms to get config variables.
However in quite a few places `getenv()` is still used and this may
preclude controlling some options on some systems.
For instance it is not generally possible to use `MESA_DEBUG` on
Android.
So replace most `getenv()` occurrences with `os_get_option()` to
support configuration options more consistently across different
platforms.
Do the same with `secure_getenv()` replacing it with
`os_get_option_secure()`.
The bulk of the proposed changes are mechanically performed by the
following script:
-----------------------------------------------------------------------
#!/bin/sh
set -e
replace() {
# Don't replace in some files, for example where `os_get_option` is defined,
# or in external files
EXCLUDE_FILES_PATTERN='(src/util/os_misc.c|src/util/u_debug.h|src/gtest/include/gtest/internal/gtest-port.h)'
# Don't replace some "system" variables
EXCLUDE_VARS_PATTERN='("XDG|"DISPLAY|"HOME|"TMPDIR|"POSIXLY_CORRECT)'
git grep "[=!( ]$1(" -- src/ | cut -d ':' -f 1 | sort | uniq | \
grep -v -E "$EXCLUDE_FILES_PATTERN" | \
while read -r file;
do
# Don't replace usages of XDG_* variables or HOME
sed -E -e "/$EXCLUDE_VARS_PATTERN/!s/([=!\( ])$1\(/\1$2\(/g" -i "$file";
done
}
# Add const to os_get_option results, to avoid warning about discarded qualifier:
# warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
# but also errors in some cases:
# error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive]
add_const_results() {
git grep -l -P '(?<!const )char.*os_get_option' | \
while read -r file;
do
sed -e '/^\s*const/! s/\(char.*os_get_option\)/const \1/g' -i "$file"
done
}
replace 'secure_getenv' 'os_get_option_secure'
replace 'getenv' 'os_get_option'
add_const_results
-----------------------------------------------------------------------
After this, the `#include "util/os_misc.h"` is also added in files where
`os_get_option()` was not used before.
And since the replacements from the script above generated some new
`-Wdiscarded-qualifiers` warnings, those have been addressed as well,
generally by declaring `os_get_option()` results as `const char *` and
adjusting some function declarations.
Finally some replacements caused new errors like:
-----------------------------------------------------------------------
../src/gallium/auxiliary/gallivm/lp_bld_misc.cpp:127:31: error: no matching function for call to 'strtok'
127 | for (n = 0, option = strtok(env_llc_options, " "); option; n++, option = strtok(NULL, " ")) {
| ^~~~~~
/android-ndk-r27c/toolchains/llvm/prebuilt/linux-x86_64/bin/../sysroot/usr/include/string.h:124:17: note: candidate function not viable: 1st argument ('const char *') would lose const qualifier
124 | char* _Nullable strtok(char* _Nullable __s, const char* _Nonnull __delimiter);
| ^ ~~~~~~~~~~~~~~~~~~~
-----------------------------------------------------------------------
Those have been addressed too, copying the const string returned by
`os_get_option()` so that it could be modified.
In particular, the error above has been fixed by copying the `const
char *env_llc_options` variable in
`src/gallium/auxiliary/gallivm/lp_bld_misc.cpp` to a `char *` which can
be tokenized using `strtok()`.

Most of the time, we can infer the type to append in
util_dynarray_append using __typeof__, which is standardized in C23 and
support in Jesse's MSMSVCV. This patch drops the type argument most of
the time, making util_dynarray a little more ergonomic to use.
This is done in four steps.
First, rename util_dynarray_append -> util_dynarray_append_typed
bash -c "find . -type f -exec sed -i -e 's/util_dynarray_append(/util_dynarray_append_typed(/g' \{} \;"
Then, add a new append that infers the type. This is much more ergonomic
for what you want most of the time.
Next, use type-inferred append as much as possible, via Coccinelle
patch (plus manual fixup):
@@
expression dynarray, element;
type type;
@@
-util_dynarray_append_typed(dynarray, type, element);
+util_dynarray_append(dynarray, element);
Finally, hand fixup cases that Coccinelle missed or incorrectly
translated, of which there were several because we can't used the
untyped append with a literal (since the sizeof won't do what you want).
All four steps are squashed to produce a single patch changing every
util_dynarray_append call site in tree to either drop a type parameter
(if possible) or insert a _typed suffix (if we can't infer). As such,
the final patch is best reviewed by hand even though it was
tool-assisted.
No Long Linguine Meals were involved in the making of this patch.

Without this, somebody trying to map a buffer for write by the CPU would
fail. This is not common to do in hardware driver environments, but it
shouldn't be disallowed, and there's no downside to allowing it.
I did skip virgl, because that's one where I don't know for sure if there
wouldn't be a downside to allowing RDWR (there are other virt exports
where RDWR is gated on a mappable flag).
This is a follow-up to !37088 to keep copy and paste from introducing the

If bo->size = lseek(); would return a failure value of bo->size ==-1,
then current error handling would return while leaving the already
allocated and cached bo for the dmabuf fd in a half initialized "zombie"
state. On a successive call to agx_bo_import() for the same fd, the
assigned bo->size == -1 would mark the bo as "already initialized",
just bumping its reference count, and then returning a dysfunctional
bo to the caller, leasing to followup failures elsewhere.
Use goto error; instead, where "error:" handling will zero-out the bo,
marking it as effectively uninitialized, and hopefully causing proper
initialization on a successive call to agx_bo_import().

In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>
See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in
And this causes build errors when building for C23:
-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
123 | #define unreachable(str) \
| ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
456 | #define unreachable() (__builtin_unreachable ())
| ^~~~~~~~~~~
-----------------------------------------------------------------------
So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.
Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.
This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.
All the instances of the macro, including the definition, were updated
with the following command line:
git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
while read file; \
do \
sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
