Use the convention for Rust subprojects that was adopted by Meson 1.5.0
and newer.
Distros would prefer to avoid vendored crate sources, and instead use
local sources from e.g. /usr/share/cargo/registry. While Meson does not
support a local registry, it can be emulated with MESON_PACKAGE_CACHE_DIR.
However, because the distro might not be using the exact version of the
package, but only one that has the same semver, packagers need to add
some hacks to rewrite the wrap files. For example, in Fedora:
export MESON_PACKAGE_CACHE_DIR="%{cargo_registry}/"
# So... Meson can't actually find them without tweaks
%define inst_crate_nameversion() %(basename %{cargo_registry}/%{1}-*)
%define rewrite_wrap_file() sed -e "/source.*/d" -e "s/%{1}-.*/%{inst_crate_nameversion %{1}}/" -i subprojects/%{1}.wrap
%rewrite_wrap_file proc-macro2
%rewrite_wrap_file quote
%rewrite_wrap_file syn
%rewrite_wrap_file unicode-ident
%rewrite_wrap_file paste
Having a common convention for the name of Rust wraps makes it possible
to perform this transformation with a script without listing
the wraps one by one, and to share the script across multiple packages
(which will be useful when QEMU starts using Rust in a similar way to Mesa).
For an example of such a script, see
https://lore.kernel.org/r/20250722083507.678542-1-pbonzini@redhat.com/.

The intent is to provide an easy way to measure the impact of an
optimization, not by measuring the whole workload completion time
but also by measuring certain chunks of the workload like command
buffers, renderpasses, or even separate draws.
A moderate perf win in a rare case may not translate into statistically
signifacant overall result. An optimization also may hurt perf in some
cases and help in other which is also hard to judge from overall perf.
For best results pin cpu/gpu frequencies and disable gpu suspend.
Exclude all unnecessary tracepoints via TU_GPU_TRACEPOINT.

This is because Android prefers it -- the project likes to make
changes to bionic that have a global effect, and using raw-syscalls
potentially complicates that. This is a backport of:
https://github.com/bytecodealliance/rustix/pull/1478
In addition, nothing in Mesa3D needs the added functionality provided
by raw syscalls.
Test:
meson setup gfxstream-build -Dvulkan-drivers="gfxstream" -Dgallium-drivers="" -Dvirtgpu_kumquat=true -Dopengl=false -Drust_std=2021
still compiles.

os_mkdir() is a simple wrapper around mkdir() or _mkdir().
Remove a bunch of unneeded #includes in dd_util.h. Testing by
compiling llvmpipe and radeonsi (the only user of the dd_util.h
header).
There's a few other mkdir() callsites that I haven't touched but
could be updated to os_mkdir().

Matching e.g. I420_10LE in Gstreamer / yuv420p10 in ffmpeg. The formats
are notably used for HDR10 videos by software decoders like dav1d, libav,
libaom and libvpx.
Use-cases include video players and editors that can allocate DMA buffers
- e.g. via udmabuf, dma-heaps, VA-API, V4L2, etc. - allowing them to avoid
unnecessary copies. Testing HDR10 playback on CI might also become easier.

This is mainly useful for enabling validation layers, but might also
be useful for a few apps that use very basic atomic operations. In
general these operations do not work properly in Bifrost, but they
work well enough to e.g. pass some piglit tests.

Gralloc is the central piece to align defaults and expectations across
different APIs. Doing so simplifies client side handling. To be noted,
midpoint chroma location is preferred as the default to skip the chroma
lowering pass. The same has been suggested by all Vulkan drivers with
AHB implemented and practiced for years under venus.

Clients are expecting the color info to be fully filled when the api
exists. Give proper defaults for the metadata to stay aligned with
legacy backends.
Also amend the missing ChromaSiting cases.

This is intended to a Rust analog to "src/util", which has
many utilities used by Mesa developers. This is mostly
a copy of ${crosvm} rutabaga_gfx/src/rutabaga_os (which will
be deleted in favor of this crate).
Key constructs include:
- SharedMemory
- MemoryMapping
- Tube (sockets, essentially)
- OwnedDescriptor (HANDLE or fd-based)
- WaitContext (epoll, ..)
As one would expect, Linux implementations are the most complete.

This shouldn't be needed anymore since f58630f07c ("radv: Always
allow sparse on normal GFX/COMPUTE/DMA queues."). These games were
always assuming that GFX queue supported sparse which wasn't correct
with the dedicated sparse queue.

- Indiana Jones: The Great Circle
- DOOM: The Dark Ages
