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.

[common] Switch to boost::unordered_flat containers (#4326)

2026-08-31T00:58:09+00:00

Replaces all instances of ankerl's unordered map/set with boost's `unordered_flat_*` classes. This uses std::hash since boost::hash is actually a lot slower. Also adds an abstraction layer in `Common` so future changes are quicker and easier. Other implementation details: - ankerl provided hash specializations for tuple and pair, so those were ported here - std::erase_if doesn't work on boost, so just used the ADL'd erase_if This should be about equal or superior performance as unordered_dense for everything except iteration.

[*] change all std::unordered_map and std::unordered_set into ankerl::unordered_dense::map/set variants (#3442)

2026-02-10T02:34:07+00:00

mainly doing this to reduce memory footprint; we all know how nice ankerl::unordered_dense is in theory 4x faster - in practice these maps arent that "hot" anyways so not likely to have much perf gained i just want to reduce mem fragmentation to ease my porting process, plus it helps other platforms as well (ahem weak Mediatek devices) :) Signed-off-by: lizzie Co-authored-by: Caio Oliveira Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3442 Reviewed-by: DraVee Reviewed-by: CamilleLaVey Co-authored-by: lizzie Co-committed-by: lizzie

[Maxwell]: Fix shaders compilation memory leak (#2606)

2025-09-30T23:21:12+00:00

Co-authored-by: collecting "The ObjectPool was never being cleared after use. When compiling complex shaders, this would allocate gigabytes of memory, causing the emulator to run out of RAM and be killed by the operating system. This is a critical fix that prevents out-of-memory crashes on all operating systems when playing games with complex shaders."
