Intel Changes It’s Stripes In The 12th Generation
TigerLake Plans To Roar
Github is an interesting place and you can find unexpected things, such as a hint at Intel’s plans for it’s 12th generation of the Core architecture. A new merge request has revealed that Intel will be making a big enough change to their execution unit ISA that the open source Mesa graphics driver will need to be vastly modified to work. This is the biggest change to Intel’s GPU instruction set in over a decade and indicates something is going to be different in Tigerlake.
There is, of course, no mention of 10nm as this post is concerned with how software will interface with the newly designed GPU and the process node makes no difference to programmers at this level. Drop by for a visit to glean more as people work to rewrite Mesa to interface with part of Intel’s upcoming generation of processors.
This merge request only includes the most critical changes to get the i965 back-end up and running on Gen12. Some performance and debugging features are still missing, including the changes required for the instruction compaction pass to handle the new ISA
