In theory you can build a driver using OpenCL kernels with a
-Dmesa-clc=system. That shouldn't require any LLVM/Clang/etc...
But the checks to find the pre-compiled mesa_clc & vtn_bindgen
binaries are in meson files or conditions only triggered if you build
with LLVM (:

This Vulkan layer allows reporting a limited VRAM size to the
application. This layer can be useful for testing applications and
games which query for the memory budget adjusting their behavior
accordingly.
They layer does not set a hard limit on the amount of VRAM thus
applications can still make allocations even though the reported
budget might indicate no memory is left, if the set limit is lower
than of actually available VRAM.

Native context support is implemented by diverting the libdrm_amdgpu functions
into new functions that use virtio-gpu.
VA allocations are done directly in the guest, using newly exposed libdrm_amdgpu
helpers (retrieved through dlopen/dlsym).
Guest <-> Host roundtrips can be expensive so we try to avoid them as much as
possible. When possible we also don't wait for the host reply in case where
it's not needed to get correct result.
Implicit sync works because virtio-gpu commands are submitted in order to the
host (there a single queue per device, shared by all the guest processes).
virtio-gpu also only supports one context per file description (but multiple
file descriptions per process) while amdgpu only allows one fd per process,
but multiple contexts per fd. This causes synchronization problems, because
virtio-gpu drops all sync primitive if they belong to the same fd/context/ring:
ie the amdgpu_ctx can't be expressed in virtio-gpu terms.
For now the solution is to only allocate a single amdgpu_ctx per application.
Contrary to radeonsi/radv, amdgpu_virtio can use libdrm_amdgpu directly: the
ones that don't rely on ioctl() are safe to use here.

Initial "compilable" version of mesa/gfxstream on Windows. For now it is
achieved through "#if !DETECT_OS_WINDOWS" directives hence it is NOT
functional. The compilation works with mingw only and the compilation is
tested in a windows host. This commit is intended to only pass the
compilation process without errors.
Also created stub code for a future windows implementation.

Rework: (Kevin)
- Properly setup bvh_layout
Our bvh resides in contiguous memory and can be divided into two sections:
1. anv_accel_struct_header, tightly followed by
2. actual bvh, which starts with root node, followed by interleaving
leaves or internal nodes.
- Update comments for some fields for BVH and nodes.
- Properly populate the UUIDs in serialization header
- separate header func into completely two paths based on compaction bit
- Encode rt_uuid at second VK_UUID_SIZE.
- Write query result at correct slot
- add assertion for a 4B alignment
- move bvh_layout to anv_bvh
- Use meson option to decide which files to compile
- The alignment of serialization size is not needed
- Change static_assert to STATIC_ASSERT and move them inside functions
Rework (Sagar)
- Use anv_cmd_buffer_update_buffer instead of MI to copy data
Rework (Lionel)
- Remove flush after builds, and add flush in copy before dispatch
- Handle the flushes in CmdWriteAccelerationStructuresPropertiesKHR properly

Commit 8f6fca89aa from !30952 by @zmike
renamed with_dri3 as with_dri in many places, but mistakenly deleted it
there, instead of renaming it. This causes the linking of gallium to fail
because of missing xcb_xfixes_destroy_region symbol from xcb-fixes.

this existed for historical reasons, but realistically now it should
be possible to build mesa with dri3 always enabled. additionally,
this check was often used as a substitute for having drm functionality,
which is sort of similar but also not really a direct match
this simplifies a bunch of conditionals and prevents users from footgunnning
themselves into orbit

This change adds a Vulkan screenshot layer that allows users to take
screenshots from a Vulkan application, but has an emphasis on
performance, decreasing the performance impact on the application
involved. This allows for automated setups to use this layer to take
screenshots for navigating various in-application menus.
This layer works by hooking into various common Vulkan setup functions, until
it enters the vkQueuePresentKHR function, and from there it copies the current
frame's image from the swapchain as an RGB image to host-cached memory, where
we will receive the information as a framebuffer pointer. From there, we copy
the framebuffer contents to a thread that will detach from the main process
so it can write the image to a PNG file without holding back the main thread.
This layer was created from using the existing overlay layer as a template,
then adding portions of LunarG's VulkanTools screenshot layer:
https://github.com/LunarG/VulkanTools/blob/main/layersvt/screenshot.cpp
More specifically, there were usages of functions, along with modifications of
various functions from screenshot.cpp in the VulkanTools project, used in
screenshot.cpp.
There are some sections of the screenshotting functionality that remain
unmodified from the original screenshot.cpp file in VulkanTools, including the
global locking structures and the writeFile() function, which takes care of
obtaining the images from the swapchain. There were various areas in which
modifications were made, including how images are written to a file (using PNG
instead of PPM, introducing threading, added fences/semaphores, etc), along
with many smaller changes.
v2: Fix segfault upon application exit
v3: Fix filename issue with concatenation, along with some leftover

This keeps the allow_fallback behavior for Lua dependency when freedreno
tools are used, like it used to be. But will disable the fallback
mechanism otherwise.
For Intel, the dependency is optional and the tool that uses is
skipped when Lua is not available, so it is fine we don't use fallback
there.

Previously only `-mtls-dialect=gnu2` was probed, which was appropriate
for arm, x86 and x86_64, but not for newer architectures such as
aarch64, loongarch64 and riscv64 which all use `-mtls-dialect=desc`
instead. Because the driver option is not consistent across
architectures (and probably will not), try both variants and choose the
first one working.
While at it, rename "gnu2_*" variables to "tlsdesc_*" respectively, for
clarity.
