Adaptive filtering of packets in a graphics processing system

A method comprising:

• filtering a first packet out of a packet stream directed to a graphics processing core, wherein the first packet is filtered based on a comparison of hardware state information included in the first packet and an adaptive list of previously received hardware state information that has been used to configure the graphics processing core;
• modifying the adaptive list in response to filtering the first packet;
• and
• wherein filtering the first packet comprises filtering a group of packets including the first packet based on a comparison of information representing a group identifier of the group of packets and configuration data in the group of packets and information representing at least one combination of a previously received group identifier and configuration data in a previously received group.

An apparatus comprising:

• a storage element to store an adaptive list of previously received hardware state information that has been used to configure a graphics processing core;
• at least one filter module to filter a first packet from a packet stream directed to the graphics processing core, wherein the filter module filters the first packet based on a comparison of hardware state information included in the first packet and the previously received hardware state information stored in the adaptive list;
• a processor to modify the adaptive list in response to filtering the first packet;
• and
• wherein the at least one filter module is configured to compare information representing configuration data in the first packet and an address indicating a destination of the configuration data to information representing at least one combination of previously received configuration data and a destination of the previously received configuration data stored in the adaptive list.

A method comprising:

• determining whether throughput of a graphics processing system is limited by a graphics processing core;
• at a software filter, selectively filtering packets from a packet stream directed to the graphics processing core to form a filtered packet stream in response to the graphics processing core limiting throughput, wherein the packets are filtered based on a comparison of hardware state information included in the packets and a first adaptive list of previously received hardware state information that has been used to configure the graphics processing core;
• modifying the first adaptive list in response to filtering the packets;
• at a hardware filter, filtering packets from the filtered packet stream based on a comparison of the hardware state information included in the packets and a second adaptive list of previously received hardware state information that has been used to configure the graphics processing core;
• and
• modifying the second adaptive list in response to filtering the packets.

An apparatus comprising:

• a storage element to store an adaptive list of previously received hardware state information that has been used to configure a graphics processing core;
• a processor to determine whether throughput of a graphics processing system is limited by the graphics processing core;
• a software filter to selectively filter packets from a packet stream directed to the graphics processing core to form a filtered packet stream in response to determining the graphics processing core is limiting throughput, wherein the packets are filtered based on a comparison of hardware state information included in the packets and a first adaptive list of previously received hardware state information that has been used to configure the graphics processing core;
• a hardware filter to filter packets from the filtered packet stream based on a comparison of the hardware state information included in the packets and a second adaptive list of previously received hardware state information that has been used to configure the graphics processing core;
• and
• the processor to modify the first adaptive list in response to filtering the packets by the software filter and to modify the second adaptive list in response to filtering the packets by the hardware filter.
