Methods and apparatus for intra-wave texture looping

An apparatus for graphics processing, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine whether to divide a group of threads into a plurality of sub-groups of threads, each thread of the group of threads being associated with a shader program;
• divide, upon determining to divide the group of threads into the plurality of sub-groups of threads, the group of threads into the plurality of sub-groups of threads;
• insert a loop marker for each of the plurality of sub-groups of threads based on a subsection of the shader program;
• and
• execute, upon dividing the group of threads into the plurality of sub-groups of threads, the subsection of the shader program for each sub-group of threads of the plurality of sub-groups of threads, the subsection of the shader program completing execution for one sub-group of threads before commencing execution for a subsequent sub-group of threads.

An apparatus for graphics processing, comprising:

• means for determining whether to divide a group of threads into a plurality of sub-groups of threads, each thread of the group of threads being associated with a shader program;
• means for dividing, upon determining to divide the group of threads into the plurality of sub-groups of threads, the group of threads into the plurality of sub-groups of threads;
• means for inserting a loop marker for each of the plurality of sub-groups of threads based on a subsection of the shader program;
• and
• means for executing, upon dividing the group of threads into the plurality of sub-groups of threads, the subsection of the shader program for each sub-group of threads of the plurality of sub-groups of threads, the subsection of the shader program completing execution for one sub-group of threads before commencing execution for a subsequent sub-group of threads.

A non-transitory computer-readable medium storing computer executable code for graphics processing, the code when executed by a processor causes the processor to:

• determine whether to divide a group of threads into a plurality of sub-groups of threads, each thread of the group of threads being associated with a shader program;
• divide, upon determining to divide the group of threads into the plurality of sub-groups of threads, the group of threads into the plurality of sub-groups of threads;
• insert a loop marker for each of the plurality of sub-groups of threads based on a subsection of the shader program;
• and
• execute, upon dividing the group of threads into the plurality of sub-groups of threads, the subsection of the shader program for each sub-group of threads of the plurality of sub-groups of threads, the subsection of the shader program completing execution for one sub-group of threads before commencing execution for a subsequent sub-group of threads.
