Yes, because Radeon PCI DRI support is experimental only on non-Alpha CPU architectures, so PCI is disabled by default. ;o) This requires you to use ForcePCIMode which is more or less a nice way of saying "I understand that this is an experimental feature, but please enable the experimental non-stable PCI DRI code so I can try it anyway, and use it if it randomly happens to work on my system." The pcigart code is known to work for some people on x86, alpha, and ppc hardware currently. It does not however work on AMD64 in my experience though, which implies that either there are issues needing debugging on AMD64 WRT pcigart - which is entirely a reasonable assumption, or else the fixes which allow pcigart to work on x86/ppc did not make it into the AMD64 kernel you are using. I suspect that it is just a generic AMD64 issue with pcigart requiring someone to debug it who is interested in seeing it work. Someone did this for x86 about 5 months back. I'm interested in seeing it work on AMD64 also, but it's unfortunately I don't have time to muck with it currently. I planned on fixing AMD64 MTRR support in XFree86 first before tackling the PCI radeon issue. There's a bug report in Red Hat bugzilla for this problem if you'd like to add yourself to the CC list. Also when I get a chance to poke at it, assuming it is still unsolved, please let me know if you're interested in doing some realtime troubleshooting and experimenting on #dri-devel on irc.freenode.net, as it is likely to be useful for narrowing things down. My recommendation, is to try using the latest official DRM code from the DRI project's CVS. Just the DRM, not all of DRI-CVS. If this works for you, please let me know. Thanks for the report, hope this helps. TTYL -- Mike A. Harris _______________________________________________ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86
