Hi list,
I ran into some trouble getting DRI running with r300 (I have no idea if
it is already supported or not), but it didn't work. I looked at xorg's
logfile and found out that DRI was disabled and I also found out that
this is caused by radeon_accelfuncs.c. So I "wrote" the attached patch
to get around that. DRI does still not work, but at least my xorg log
tells me it does :-)
!! WARNING !!
I have no idea what I'm doing, so this might be completely wrong :-)
!! WARNING !!
PS: The webpage of r300 is missing a tutorial ;)
PPS: Patch has been applied for a already patched file, I guess, so line
numbers might be completely wrong.
PPPS: I used xorg-x11-6.8.1 from gentoo Linux (xorg-x11-6.8.0-r1 to be
exact)
PPPPS: I'm having a Radon 9700 Pro from ELSA.
That's it for now, regards,
Christoph Brill aka egore
