Variables that are only used for assertions are considered unused in release
builds. Don't treat this as an error, since we build with -Werror even for
release in CI. This causes reasonable code to build and pass tests locally (and
therefore to be queued for merge by reasonable developers), but later fail in CI
due to a variable used only as an assertion. This pattern is common enough we
have an ASSERTED macro to workaround the behaviour, but failing a CI run to
have the author go back and add in the ASSERTED and re-queue later is a recipe
for frustration, wasted time, and wasted CI bandwidth.
Disable this behaviour to reduce CI friction.
In my view, sprinkling in ASSERTED clutters the code, rather than helps; I find
CI's insistence on doing so actively counterproductive. Developers are free to
continue doing so after this change. But this way CI won't fail merge requests
over it. After all, CI enforces policy, and we shouldn't have "mark variables
only used for assertions as ASSERTED" as policy. Let's pick our battles wisely
and improve CI's signal-to-noise ratio.
As an added benefit, this eliminates a class of defects where ASSERTED is used
incorrectly, e.g:
c91e3c6a42 ("util: Should not use ASSERTED in util_thread_get_time_nano")
3e22fc27af ("zink: remove incorrect ASSERTED macro")
0d08ce287b ("pan/bi: Remove dated ASSERTED properties")
Note that actual unused variables will be caught by debug builds. It is expected
that developers do debug builds locally before ramming code through CI, so that
should be caught.

__DRI_DRIVER_GET_EXTENSIONS. xserver has supported that since 1.15.0,
which is almost nine years old now.

Add a new backend to enable using native driver in a VM guest, via a new
virtgpu context type which (indirectly) makes host kernel interface
available in guest and handles the details of mapping buffers to guest,
etc.
Note that fence-fd's are currently a bit awkward, in that they get
signaled by the guest kernel driver (drm/virtio) once virglrenderer in
the host has processed the execbuf, not when host kernel has signaled
the submit fence. For passing buffers to the host (virtio-wl) the egl
context in virglrenderer is used to create a fence on the host side.
But use of out-fence-fd's in guest could have slightly unexpected
results. For this reason we limit all submitqueues to default priority
(so they cannot be preepmted by host egl context). AFAICT virgl and
venus have a similar problem, which will eventually be solveable once we
have RESOURCE_CREATE_SYNC.

Meson devenv is a feature added in meson 0.58 (thus the features is
version guarded) that allows creating a shell environment with
environment variables automatically setup for running the project inside
the build dir. Some variables (such as LD_LIBRARY_PATH and PATH) are set
automatically, others must be added by the project.
For vulkan is is relativley simple, we create a new, uninstalled, icd
file for each driver and set the VK_ICD_FILENAMES variable
appropriately. This can be used with:
```sh
meson devenv -C $builddir
```
then, vulkan applications will automatically use the uninstall vulkan
driver, no need to install.

If we don't do this, and we are statically linking LLVM
(-Dshared-llvm=disabled) while using a version of LLVM compiled for a
general-purpose distribution, then the link fails with undefined
references to the functions called by LLVMInitializeAllTargets().
Using a version of LLVM that was built specifically for Mesa will
sometimes mask this: if the only backends built into LLVM are backends
that we specifically link anyway, then the link will succeed.
According to commit 80817b6e "meson: Adjust Clover's required LLVM
modules", all-targets is not available when using CMake to locate LLVM,
so make it optional rather than mandatory.
This partially reverts commit 80817b6e34.

run_command will change the default for the check arg to true
in the future. If it is true then meson will exit if the command
fails. It must be false here as we check the return code to
provide a meaningful error message.
With meson 0.61 we get the following warning:
WARNING: You should add the boolean check kwarg to the run_command call.
It currently defaults to false,
but it will default to true in future releases of meson.

For getting the fd from the device.
This uses the new function introduced with libdrm 2.4.109. This has
already been updated in CI and is already required for mesa common
bits so requiring it for libdrm_amdgpu is no big deal.

This fixes building on macOS:
Disable ZINK_USE_DMABUF on macOS, it is unsupported.
Import vk_mvk_moltenvk.h for MVK_VERSION in zink_resource.c.
Add additional build arguments (see meson.build) to build properly.
To build on macOS, you will probably need to run:
brew install bison llvm cmake libxext xquartz ninja xorgproto meson
And you also need to setup meson with something like:
-Dmoltenvk-dir=/Users/<Username>/VulkanSDK/<VersionNumber>/MoltenVK
-Dc_std=c11

Before meson 0.48 the cpu_family() would return 'ppc64le' on little
endian power8. In newer versions it returns 'ppc64' and endianness
should be checked with endian()
We now require meson >= 0.53 so we can drop the compatability with
older versions.

This bumps the supported dma-buf version up to 4 and adds the initial
dma-buf feedback implementation. It follows the changes in the dma-buf
protocol extension [1] to include the dma-buf feedback interface, which
should be incorporated by most Wayland compositors in the future.
From version 4 onwards, the dma-buf modifier events are not sent by the
compositor anymore, so we use the default feedback to pick the set of
formats/modifiers supported by the compositor. Also, we try to avoid the
wl_drm device event and instead use the dma-buf feedback main device. We
only fallback to wl_drm when the compositor advertises a device that
does not have a render node associated.
In this initial dma-buf feedback implementation we still don't do
anything with the per-surface dma-buf feedback, but in the next commits
we add proper support.
It's important to mention that this also bumps the minimal supported
version of wayland-protocols to 1.24, in order to include [1].

TLSDESC speeds up access to dynamic TLS. This is especially important
for non-glibc targets, but is also helpful for non-initial-exec TLS
variables.
The entry asm does not support TLSDESC, but it only accesses
initial-exec symbols, so it is not necessary to handle that separately.

This might be safe to relax to all Windows compilers, but I didn't
test Clang or MinGW, so scoping to MSVC for now. For MSVC, this is
safe to mismatch, because the vftables are emitted into all objects
with "pick largest," and the definition with RTTI is larger than the
one without. This is different than the Itanium ABI, which only emits
one copy of the typeinfo in the object which defines the key method.
