Abstract

Provided is a method for processing a command in a computing system including an accelerated processing device (APD) having a command processor. The method includes executing an interrupt routine to save one or more contexts related to a first set of instructions on a shader core in response to an instruction to preempt processing of the first set of instructions. Provided is also a method that resumes an accelerated processing device (APD) wavefront in which a subset of elements have faulted. A restore command for a job including a wavefront is received. A list of context states for the wavefront is read from a memory associated with a APD. An empty shell wavefront is created for restoring the list of context states. A portion of not acknowledged data is masked over a portion of acknowledged data within the restored wavefronts.
