Intel's Open-Source Vulkan Driver Wires Up Mesh Shader Queries

Building atop the Intel "ANV" Vulkan driver's mesh shader support that's been enabled by default since last year, the newest Mesa 24.2-devel code as of today now adds support for mesh shader queries.

The Intel ANV driver now enables "meshShaderQueries" for creating query pools of the VK_QUERY_TYPE_MESH_PRIMITIVES_GENERATED_EXT query type and statistic queries of the mesh and task shader flags.

"Mesh shader queries include mesh-primitives-generated count and task/mesh shader pipeline statistics."

The mesh shader queries support landed via this merge request for Mesa 24.2 that aims to be out in August.

Mesa 24.2 has also been seeing a lot of work on Intel Xe2 graphics for Lunar Lake and Battlemage, HiZ on multi-LOD depth buffers, and a variety of different Vulkan extensions being wired up in recent weeks.
