Claim 7:
8. A method comprising:
executing, by circuitry of a plurality of execution units, a plurality of thread groups;
downsampling, by each thread group of the plurality of thread groups in parallel, a different patch of a source texture to generate one or more mipmap levels for the source texture;
maintaining an indication as to how many of the plurality of thread groups have or have not completed execution;
executing a last active thread group of the plurality of thread groups to compute remaining mipmap levels for the source texture, responsive to the indication indicating all other thread groups of the plurality of thread groups have completed downsampling a respective patch down to a single texel; and
rendering pixels to be driven to a display based on one or more mipmap level texels.
