Instead the complicated logic we currently have, do this :
We start with this shader :
int main() {
...
if (...) {
SetMeshOutputsEXT(0, 0);
return;
} else {
SetMeshOutputsEXT(...);
}
...
}
We turn it into this :
int main() {
uint __temp_prim_count = 0;
...
if (...) {
__temp_prim_count = 0;
return;
} else {
__temp_prim_count = ...;
}
...
if (is_first_group_lane()) {
SetMeshOutputsEXT(..., __temp_prim_count);
}
}
This works because the SPIRV spec says this :
"The arguments are taken from the first invocation in each
workgroup. Any invocation must execute this instruction no more
than once and under uniform control flow."

When WSI is working in prime/dma-buf mode, it has one additional
VkBuffer or VkImage where the main VkImage is copied to without any
compression or tiling different from linear
The batch buffer to do this copy is created in
wsi_finish_create_blit_context(). It performs a barrier transitioning
the VkImage to VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL, performs the
copy, and then transitions it back to VK_IMAGE_LAYOUT_PRESENT_SRC_KHR.
However, in this prime/dma-buf mode, no display modifiers are involved,
which causes compression to be disabled when switching to
VK_IMAGE_LAYOUT_PRESENT_SRC_KHR.
This change adds an exception to allow the Vkimage to remain compressed
because we can handle the compressed-to-uncompressed copy.
Doing so fixes an issue that was reported with BMG + integrated GPU
and should also improve performance by keeping the VkImage compressed.

The Xe uAPI is designed to use bind queues such that binds without input
dependencies (sync objects) do not block on binds with input
dependencies.
For example:
- Bind A (sparse) is submitted with a list of input dependencies.
- Bind B (immediate) is subsequently submitted without a list of input
dependencies.
If Bind A and Bind B share a single bind queue, Bind B will not be
scheduled until Bind A completes. Using individual bind queues decouples
Bind A and Bind B, allowing Bind B to make immediate progress.
This change creates a separate bind queue for each ANV queue, enabling
support for sparse bindings that may have input dependencies.
v2:
- Bail on bind queue creation failure (Linoel)
- Only create bind queue if VK_QUEUE_SPARSE_BINDING_BIT is set (Jose)
v3:
- Add comment around submit->queue usage (Jose)

On gfx12+, the pre-amble and post-amble flushes contain the stalls
necessary to ensure the prior operation is complete. Remove the extra
uses of ANV_PIPE_END_OF_PIPE_SYNC_BIT in post-amble flushes. Also do
this for the pre-amble flushes, but this doesn't have any impact. The
flush application function will implicitly add the bit.
For A750, this improves the TWWH3 trace in the performance CI by 0.52%
(n=2).

Fast-clears require expensive flushes beforehand and afterwards. The
cost of flushes are decreased in a series of back-to-back fast-clears as
no extra fast-clear flushes are required in between them. If the ratio
of a command buffer's recorded back-to-back fast clears over independent
fast-clears falls below 1/2, prevent that command buffer from recording
any further fast-clears.
Averaging two runs of our Factorio trace on an A750 shows a +14.37%
improvement in FPS.

This patch exposes shader hashes (computes and draws) to Perfetto and
utrace. By including these hashes in traces, developers can correlate
compute and draw calls with their assoicated ASM dumps when analyzing
the traces.
To achieve this, intel_tracepoint.py has been reworked to preprocess
tracepoint arguments dynamically. Any argument containing "hash" in its
variable name is now forrmated as hexadecimal before being passed to the
tracepoint definition.
