Mesh Shader Work Distribution

An apparatus, comprising:

• buffer circuitry;
• shader circuitry configured to execute graphics programs, including mesh shaders that store output data in the buffer circuitry;
• primitive processing circuitry configured to read data from the buffer circuitry and process the data, including to cull primitives that are not visible in a graphics frame;
• vertex control circuitry configured to:
• determine an amount of buffer space in the buffer circuitry currently utilized by output data stored in the buffer circuitry;
• and
• adjust distribution of mesh shader work to the shader circuitry based on the determined amount of buffer space.

A method, comprising:

• executing, by a computing system, graphics programs, including mesh shaders that store output data in a buffer;
• reading, by the computing system, data from the buffer and processing the data, including culling primitives that are not visible in a graphics frame;
• determining, by the computing system, an amount of buffer space in the buffer currently storing output data;
• and
• adjusting, by the computing system, distribution of mesh shader work based on the determined amount of buffer space.
