This is helpful to tell which path is taken:
1. explicit modifier: legacy_scanout=0, prime_blit=0
2. prime blit: legacy_scanout=0, prime_blit=1
3. legacy scanout: legacy_scanout=1, prime_blit=0
To be noted, venus doesn't advertise legacy scanout support, but we
implicitly support it for gamescope compatibility.

To avoid incompatibility between the compiler implementations used by
the driver and the renderer, seq_cst ordering is picked here, which has
required a full mfence instruction. Then the renderer side acquire is
ensured to be ordered after the cache flush of ring cs updates.
Perf wise, there's no regression in headless vkmark runs. In theory,
the overhead introduced here weighs trivially as compared to the ring
cs encode/decode part. So we should go for better robustness.

Now that lavapipe sparse resource support on external memory has been
fixed, expose sparse resource support from venus on lavapipe. Meanwhile,
make remaining failures explicit (failed in lavapipe as well).
This CL also drops an obsolete comment and updates expectations from

Now sfb cmd can be VK_NULL_HANDLE on incompatible queues. Avoid passing
that to set cmd, and explicitly assert below.

Previously, we either have to filter out incompatible queue or disable
fence feedback. Now we track whether the queue can do feedback, and will
mark the fence feedback not pollable if the fence is submitted on an
incompatible queue.

Feedback requires transfer capability, so we must skip feedback cmd
pool initialization on incompatible queue families. Meanwhile, use
pool_handle for all validity check needed.
- fence and semaphore feedback: skip feedback cmd alloc and record when
pool_handle is VK_NULL_HANDLE
- event feedback: not affected as we patch in-place upon recording
- query feedback: assert the feedback cmd alloc is on supported queue

This was something that came up in the slop MR. Not sure it's actually a
good idea or not but kind of curious what people think, given we have a
sound tool (Coccinelle) to do the transform. Saves a redundant branch
but means extra noninlined function calls.. likely no actual perf impact
but saves some code.

This reduces duplication: we only need to distinguish between Windows
and Unix in one place.
The previous code was inconsistent about using either the `platforms`
option, or the `host_machine`. Following the logic described in
commit 94379377 "lavapipe: build "Windows" check should use the host machine, not the `platforms` option.",
I've assumed that checking the host machine is the more-correct version
and used that.

This consistently uses `NAME.dll` on Windows, `libNAME.dylib` on Darwin
derivatives such as macOS, and `libNAME.so` on Linux, *BSD and so on.
It's also consistent about using the local variable name `icd_file_name`
for this name in every Vulkan driver, which was already the case in many
but not all drivers.
Some of these drivers probably don't make sense (or don't work) on
Windows and/or macOS, but if this is kept consistent for all drivers,
it should avoid the need for driver-specific commits like
commit 611e9f29e "lavapipe: fix icd generation for windows",
commit 951f3287 "lavapipe: set empty dll prefix",
commit 13e7a39f "lavapipe: fixes for macOS support",
commit 7008e655 "radv: Update JSON generator if Windows" and so on,
each time a driver is found to be relevant on more platforms than
previously believed.

Venus renderer side has strict entry points sanitization based on the
app requested app api version + physical device api version. So on the
driver, we should follow the same for legacy client apps.
Meanwhile, VK_PIPELINE_STAGE_NONE can't be used when we hit the sync2
emulation path, so we swap it with VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT
placeholder for the 2nd sync scope there.

In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>
See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in
And this causes build errors when building for C23:
-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
123 | #define unreachable(str) \
| ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
456 | #define unreachable() (__builtin_unreachable ())
| ^~~~~~~~~~~
-----------------------------------------------------------------------
So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.
Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.
This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.
All the instances of the macro, including the definition, were updated
with the following command line:
git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
while read file; \
do \
sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
done && \

Prepare for adopting common runtime so that we don't leave unused vars

Instead of failing the import, drop the mappable bit if blob size is
smaller than the requested alloc size, which defers the error to the
intended vkMapMemory api call if the client app requests Vulkan mapping
from the imported external memory.
Normally this won't occur if the app obeys the spec with a properly
implemented blob mem allocator. However, legacy allocators like minigbm
virtgpu_virgl backend could allocate via virgl w/o knowing the real blob
size from the guest side. The unsatified cases are external gralloc
images, which won't be mapped in any meaningful way after being
imported. This is to prepare dropping the force_unmappable workaround,
and to further prepare adopting common Android runtime.

It is a tech debt now since NV proprietary is on sw wsi path, and
rendering to the prime blit dst buffer may never get supported there.
For later, when performance optimization is needed for venus on nv, we

Gamescope relies on legacy scanout support when explicit modifier isn't
available and it chains the mesa wsi hint requesting such. Venus doesn't
support legacy scanout with optimal tiling on its own, so venus disables
legacy scanout in favor of prime buffer blit for optimal performance. As
a workaround here, venus can once again force linear tiling when legacy
scanout is requested outside of common wsi.
