Since Sandybridge, DP supports cache select for read/write. Some write messages such as
OWord Block Write don't support render cache any more on Ivybridge. So introduce a
generic data_port messsage for Sandybridge+.
data_port(
cache_type, /* sampler, render, constant or data(on Ivybridge+) cache */
message_type, /* read or write type */
message_control,
binding_table_index,
write_commit_or_category, /* write commit on Sandybridge, category on Ivybridge+ */
header_present)

intel-gen4asm is a program to compile an assembly language for the Intel 965 Express Chipset. It has been used to construct programs for textured video in the 2d driver. Some examples of gen4 assembly programs are in the doc/examples directory. Note that the language parsed by this assembler is not exactly what the final language is going to look like. In particular, the send instructions need to be cleaned up and made more reasonable to program with.
