De-prioritization supporting frame buffer caching

A system comprising:

• memory;
• and
• a processor operable to interact with the memory, and configured to:
• encode a set command that references a resource group within a command buffer, wherein the set command causes a data set identifier (DSID) to be associated with the resource group that includes a plurality of graphics application program interface (API) resources;
• encode a write command that references the resource group within the command buffer that causes a graphics processor to write data into a cache line within a memory cache, wherein the write command causes the DSID to be tagged with the cache line;
• encode a de-prioritize command that references the DSID to allow for reassignment of the DSID associated with the resource group and that causes the graphics processor to notify the memory cache to later flush content from the cache line associated with the DSID and to later invalidate the cache line such that the memory cache waits to flush the content and invalidate the cache line until higher priority content is received;
• and
• commit one or more command buffers that include the set command, the write command, and the de-prioritize command for execution on the graphics processor.

A non-transitory program storage device, readable by a processor and comprising instructions stored thereon to cause the processor to:

• obtain commands from one or more command buffers, the commands including a write command and a de-prioritize command that are associated with a data set identifier (DSID), wherein the DSID is associated with a resource group that includes frame buffer content and a cache line in a memory cache;
• execute the write command to write data within the cache line to generate a dirty cache line, wherein the write command causes the cache line to be associated with the DSID;
• and
• execute, after the write command, the de-prioritize command to allow for reassignment of the DSID associated with the resource group, to notify the memory cache to later flush content from the dirty cache line associated with the DSID, and to later invalidate the dirty cache line such that the memory cache waits to flush the content and invalidate the dirty cache line until higher priority content is received.
