The application is not complex, but it is cost sensitive, so = the Coral-P doesn't seem a good choice. Our main need is only to have a frame buffer to draw on, but sure it = would be interesting to support X11 too. You comment about a Coral-P 'successor' more adapted to big endian = processors.

Yes, but only the Coral-P, and X11 only correctly using a modified X server (xfree86 and xorg). The problem is the endianess. The Coral-P does not contain a byte swapper for the video memory, so it cannot be easily be used with a big endian CPU like many other grafik chips. Even the successor of the Coral-P has such a byte swapper. Our modifications to support Z-images are done in the non-accelerated driver in the shadow frame buffer extension. The Coral-P accelerated driver wasn't very stable when we tested it a while ago, I assume this very much depends on the functions you use. Roman --=20 Roman Fietze Telemotive AG B=FCro M=FChlhausen
