This extension seems to be supported on GC3000 (HALTI2) and later hardware.
While no explicit feature bit documents this capability, testing
confirms that the required vertex formats work correctly on these GPUs.
This patch adds the missing B10G10R10A2 vertex format variants
(UNORM, SNORM, USCALED, SSCALED), gates support behind the HALTI2
feature check, and updates features.txt to reflect the new capability.
All relevant piglit tests pass.

Netcat locks on to the first connection so if one tried to use
breadcrumbs again Netcat will appear as if it didn't receive
anything. Use `-k` so that it accepts another connection.

This is used by Steam Link VR (driver_vrlink) to avoid doing YUV conversion itself.

Adds build instructions and workarounds documentation.
Workarounds documentation only has the biggest offenders and
there are probably way more in code that need yet to be
documented.

This description was incorrect in that it impiled we supported Hopper
and Blackwell A, which is not currently the case (see nvk_is_conformant
in nvk_physical_device.c).

Add a new MESA_LOG_PREFIX environment variable that allows fine-grained
control over log prefixes in file logger output on Linux. The variable
accepts a comma-separated list of options:
- "tag": include the tag prefix (e.g., "MESA:")
- "level": include the level prefix (e.g., "info:")
By default, both tag and level are included. Users can customize the
prefix by setting MESA_LOG_PREFIX to any combination (e.g., "tag",
"level", "tag,level", or empty string for no prefix), making the output
more flexible and readable for different use cases.
Other loggers (syslog, Android logcat, Windows debugger) are unaffected
and continue to include tag and level information as appropriate for
their format.

I routinely don't update the docs because the build (hawkmoth in
particular) is a pain. The prior instructions almost worked, except that
on Debian you need to use a venv (which is a good idea to do for py3-clang
as well for reproducibility, anyway), and the versions that were listed
didn't actually run any more due to a revoked dependency.

Setting MESA_VK_VALIDATE_SHADER_BINARIES will cause the shader code to
round-trip every shader through [de]serialize and only ever use the
deserialized version. This catches bugs where the driver may drop
things in the [de]serialization process. It also deserializes the new
shader again and compares it against the original to ensure that
deserialize -> serialize is idempotent.

This binary that perfetto builds automatically launches traced and
traced_probes, doesn't need tmux installed, doesn't need you to know tmux
ui, and doesn't need the tmux helper script hacked to not call the wrong
arch's ninja if you cross compiled.
Also, it's silly to send people into an explanation and links to docs,
when we have the instructions they actually want below.

This change adds the minimum support for VK_EXT_device_memory_report,
which only reports device memory events at this point. We can make it
more useful later (like what's done in ANV) if desired by some tools.

NIR+ACO is the best SSA-based shader compiler for AMD GPUs that exists.
There are many reasons why NIR+ACO is better than LLVM, and I have a long
list that I've collected over the years, but the major ones are better GPU
performance (faster GPU memory access thanks to better clauses and
scheduling, a lot less SGPR/VGPR spilling, better loop support, slightly
smaller shader binaries), 8x lower shader compile times, and smaller memory
footprint of the IR.
It also shows that NIR is a mature SSA-based shader compiler that helps
drivers generate optimized code very quickly.
And most importantly, radeonsi has slightly better Viewperf performance
with NIR+ACO than LLVM, and that's difficult to ignore.
