Method and system for implementing a multi-threaded api stream replay

A system for debugging, comprising:

• a multi-threaded processor for executing a plurality of function calls generated by a graphics application in association with a frame;
• a graphics application programming interface (API) configured to execute said plurality of function calls to generate said frame suitable for display, wherein said plurality of function calls is associated with one or more thread specific resources used at an entry point of capturing said frame;
• an interception layer configured to intercept said plurality of function calls between said graphics application and said graphics API in response to a request for capturing said frame, wherein said interception layer is configured to capture for each thread, a corresponding state for each corresponding thread specific resource utilized at said entry point;
• a plurality of capture streams each configured to capture executed function calls from a corresponding application thread, wherein application threads and capture streams exist in a one-to-one relationship;
• and
• a plurality of replay threads each configured to replay corresponding captured function calls originally executed on a corresponding application thread, wherein capture streams and replay threads exist in a one-to-one relationship;
• and
• an arbiter configured for ordering a plurality of captured function calls captured across said plurality of application threads in the order they were executed by said graphics application, and wherein said arbiter replays a plurality of captured function calls in the order they were captured.

A computer system comprising:

• a processor;
• and
• memory coupled to said processor and having stored therein instructions that, if executed by said computer system, cause said computer system to execute a method of debugging comprising:
• receiving a request for capturing a frame generated by a graphics application implementing a plurality of application threads for executing a plurality of function calls generating said frame, wherein said plurality of function calls is associated with one or more thread specific resources used at an entry point of said capturing;
• for each thread, determining a corresponding state at said entry point for each corresponding thread specific resource utilized;
• for each application thread, establishing a corresponding capture stream, wherein application threads and capture streams exist in a one-to-one relationship;
• for each thread, capturing executed function calls into said corresponding capture stream;
• ordering a plurality of captured function calls captured across said plurality of application threads in the order they were executed by said graphics application;
• for each capture stream establishing a corresponding replay thread, wherein capture streams and replay threads exist in a one-to-one relationship;
• and
• replaying a plurality of captured function calls in the order they were captured, wherein a captured function call is executed in a corresponding replay thread based on which application thread executed said captured function call.
