Earlier this month we shared that X.Org 7.4 will lose DRI2 support. Direct Rendering Infrastructure 2 (DRI2) was just conceived one year ago and X.Org 7.4 would have been the first release with this technology that allows for directed rendering to redirected windows. DRI2 though was delayed though since it had to be reworked due to Intel switching memory managers from TTM to GEM (Graphics Execution Manager). The first bits of the revised code have now hit the master git tree for Mesa and the X Server.

These changes to the Direct Rendering Infrastructure 2 code involve dropping the use of SAREA and implementing swap buffers in the X Server. Details on the DRI2 design can be found on the X.Org Wiki. DRI2 is now a feature for X.Org 7.5 / X Server 1.6.
