Shader profiler

A non-transitory program storage device comprising instructions stored thereon to cause one or more processors to:

• obtain a trace for execution of compiled shader program, the compiled shader program having a plurality of overlapping instruction sequences, each overlapping instruction sequence having one or more binary instructions, the compiled shader program having a corresponding plurality of source code instructions;
• execute the trace a plurality of times to obtain trace packet content for the plurality of overlapping instruction sequences;
• identify an overlapping instruction sequence of the compiled shader program that is uninterrupted when executing the trace and parse the trace packet content to determine a time duration for each binary instruction of the identified instruction sequence;
• determine an execution duration for the identified instruction sequence based on the parsed trace packet content;
• identify one or more of the source code instructions corresponding to each binary instruction of the identified instruction sequence;
• determine a time duration for each of the identified source code instructions of the identified instruction sequence based on the time duration for the identified source code instructions' corresponding binary instruction;
• and
• display the identified source code instructions and each source code instruction's corresponding time duration.

A system comprising:

• a central processing unit (CPU),
• a graphics processing unit (GPU), and
• a memory coupled to the device CPU and the GPU, wherein the memory comprises instructions to—
• obtain a trace for execution of a compiled shader program having a plurality of overlapping instruction sequences, each overlapping instruction sequence having one or more binary instructions, the compiled shader program having a corresponding plurality of source code instructions;
• execute the trace a plurality of times to obtain trace packet content for the plurality of overlapping instruction sequences;
• identify an overlapping instruction sequence of the compiled shader program that is uninterrupted during when executing the trace and parse the trace packet content to determine a time duration for each binary instruction of the identified instruction sequence;
• determine an execution duration for the identified instruction sequence based on the parsed trace packet content;
• identify one or more of the source code instructions corresponding to each binary instruction of the identified instruction sequence;
• determine a time duration for each of the identified source code instructions of the identified instruction sequence based on the time duration for the identified source code instructions' corresponding binary instruction;
• and
• display the identified source code instructions and each source code instruction's corresponding time duration.
