Abstract: A method of context bouncing includes receiving, at a command processor of a graphics processing unit (GPU), a conditional execute packet providing a hash identifier corresponding to an encapsulated state. The encapsulated state includes one or more context state packets following the conditional execute packet. A command packet following the encapsulated state is executed based at least in part on determining whether the hash identifier of the encapsulated state matches one of a plurality of hash identifiers of active context states currently stored at the GPU.
