    Abstract: An apparatus comprises a processor to perform tile-based rendering to build a command buffer without knowledge whether the contents of a cache will be discarded, and a memory to store the command buffer. The processor is to determine a discard state of the cache prior to executing the command buffer, execute the command buffer, and discard or keep the contents of the cache according to the discard state. The command buffer can sample discard control from memory immediately before the processor executes the command buffer. The discard control in memory can be updated after the command buffer is queued and before the processor executes the command buffer.
