shader_recompiler: translate Switch 2 task and mesh programs

2026-11-01T16:29:29+00:00

Mario Kart World draws some of its geometry with NVN task and mesh programs (the task program culls and writes the mesh workgroup count and a payload to its stage buffer; each mesh workgroup reads it back and writes vertices and primitives). Add Task and Mesh stages and translate them for VK_EXT_mesh_shader: - the ISBE pseudo instruction from the lowering becomes reads and writes of an emulated stage buffer: the task's output region is the task payload, the mesh output regions live in workgroup memory - every EXIT of these stages jumps to one final return, so all invocations reach the epilogue: a barrier, then OpEmitMeshTasksEXT, or OpSetMeshOutputsEXT and a copy of the 32-element vertex and primitive groups (lines named by the mesh header's and the pass-through geometry header's output maps) to arrayed and per-primitive outputs - Sirit lacks the two mesh instructions: they are emitted as OpStore markers and replaced after assembly - fragment inputs a mesh program writes per primitive get PerPrimitiveEXT The captured task and mesh programs of the title translate to SPIR-V that spirv-val accepts.

[vulkan] Fixed dual-source blending to correctly map shader outputs. (#3637)

2026-03-03T00:54:57+00:00

Fixes Skyward Sword HD eye gitch and a related MoltenVK crash due to the incorrect output mapping. Verified working on mac and android. The test in vk_pipeline_cache.cpp is a bit ugly, but it didn't seem worth it to go lambda/macro just to make it look cleaner. Could change if necessary.

Thank you to Ryujinx (riperiperi specifically) for the pointer towards clip distances Huge thanks to crueter for finding where the code works and Camille for giving pointers along the way.
