Detailed Description

MTLShader implements shader compilation, Pipeline State Object (PSO) creation for rendering and uniform data binding. Shaders can either be created from native MSL, or generated from a GLSL source shader using #GPUShaderCreateInfo.

Shader creation process:

• Create MTLShader:
  • Convert GLSL to MSL source if required.
• set MSL source.
• set Vertex/Fragment function names.
• Create and populate MTLShaderInterface.

bake_compute_pipeline_state()

MTLComputePipelineStateInstance * blender::gpu::MTLShader::bake_compute_pipeline_state	(	MTLContext *	ctx,
		MTLComputePipelineStateDescriptor &	compute_pipeline_descriptor )

If Max Total threads per threadgroup tuning parameters are specified, compile with these. This enables the compiler to make informed decisions based on the upper bound of threads issued for a given compute call. This per-shader tuning can reduce the static register memory allocation by reducing the worst-case allocation and increasing thread occupancy.

NOTE: This is only enabled on Apple M1 and M2 GPUs. Apple M3 GPUs feature dynamic caching which controls register allocation dynamically based on the runtime state.

bake_current_pipeline_state()

MTLRenderPipelineStateInstance * blender::gpu::MTLShader::bake_current_pipeline_state	(	MTLContext *	ctx,
		MTLPrimitiveTopologyClass	prim_type )

Bakes or fetches a pipeline state using the current MTLRenderPipelineStateDescriptor state.

This state contains information on shader inputs/outputs, such as the vertex descriptor, used to control vertex assembly for current vertex data, and active render target information, describing the output attachment pixel formats.

Other rendering parameters such as global point-size, blend state, color mask etc; are also used. See mtl_shader.h for full #MLRenderPipelineStateDescriptor.

Populate global pipeline descriptor and use this to prepare new PSO.
