Absolutely, otherwise it's a bug. FWIW, the DRM from DRI CVS seems to work the same here as the one from the linuxppc-2.5 tree shortly before the -test5 merge. The only recent change I see which might cause problems is my Radeon AGP => GART cleanup; I tried hard not to break anything but may have missed something. Jon, please rule out local modifications on your side and a bad build (the Makefile dependencies aren't exactly perfect, e.g.) and provide more details. -- Earthling Michel Dänzer \ Debian (powerpc), XFree86 and DRI developer Software libre enthusiast \ http://svcs.affero.net/rm.php?r=daenzer ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
