Implement a mitigation for VM faults caused by SMEM reading
from NULL descriptors.
In order to satisfy VKD3D-Proton's expectations on mutable
descriptors, we must do this in shader code, it is not
sufficient to use the address of a mapped BO when writing
null descriptors. It is not feasible to mitigate this
in VKD3D-Proton.

RDR2 VRAM memory management when resizable BAR is enabled seems
incorrect because it keeps allocating VRAM without freeing anything.
This introduces a drirc option to emulate a fake carveout of 256MiB to
workaround this game bug. This also adjust memory budgets by
distributing it between visible and invisible because AMDGPU reports
the same value for both when REBAR is enabled.

RADV_PERFTEST=sparse is a new option to enable experimental
support for sparse features when they aren't enabled by default:
- gfx6 supports sparse, albeit with a reduced feature set
- gfx7 supports 3D images (with non-standard block shape)
and unaligned mip sizes
- gfx8 supports the same feature set as gfx7
(Polaris behaves more stable than other gfx8, so we had
already enabled it by default on Polaris for a long time.)
We pass all dEQP-VK.*sparse* tests on gfx6-8 when running on
a single thread however it may cause hangs or failures
when executing the tests on multiple parallel jobs.
We plan to enable this by default when we deem it stable enough.
Until then, users can already test some games that use it.
Note, at the moment there are some unsolved problems in the
amdgpu kernel driver regarding sparse bindings on these GPUs.

GTK is missing a semaphore between QueueSubmit() and QueuePresent()
causing the WSI submit to be "unordered" and to immediately signal the
semaphores (because it's missing a wait semaphore in QueuePresent()).
The workaround is to disable unordered WSI submits until GTK fixes it
properly.

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()`.

The shaders in question use:
(memory_load + (gl_SubgroupSize - 1)) & ~(gl_SubgroupSize - 1)
My guess is that this is supposed to be the subgroup size of whatever
produced the value, not the subgroup size in this shader.
And because in the consumer the workgroup size is 32, we use wave32.

vkd3d-proton (DX12) and Zink (GL) have always been enabling features
that require the global BO list to be enabled.
Since DXVK 2.7+ (August 2025), it's also always enabled by default for
DX9-11 games (because it requires BDA now).
The global BO list used to decrease performance in the past mostly
because of bad memory management in AMDGPU, but it seems the situation
slightly improved since. Though, there might still some workloads that
hit the issue, but I think it should be mostly good overall.
This introduces RADV_DEBUG=nobolist to disable the global BO list
when no features require it.
