The DRM is necessary for EXA and Xv (as well as an updated DDX). And based on the conversations between Robert and the Linux/ATI folks, it is not as simple as merging the changes in. The new gart support necessary for r600/r700 cards, for example, is completely linux specific, as I understand it. > I'm also hoping to see support for DRI and Xv and even 3D in RV780 > chipsets soon, esp. now that AMD has finally decided to release the > RV600/700 specs to the public: > > http://www.phoronix.com/scan.php?page=article&item=amd_r600_oss_3d&num=1 > > -cpghost. The specs are not yet available. The only thing newly available is the DRM and updated DDX. The specs be available as soon as they finish sanitizing the documents and get approval. This will hopefully be "soon". :-) Adam -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
