Re: asm statement in include/asm not ansi conform

after some testing dri works now. On startup X says "dri enabled" and
glinfo shows many supported GL functions. But at least when running
"gears" for example, I get no accelaration at all. Still 60 frames per
second - same as with software rendering. I also have a P-III/500 box with
Rage128 (AGP) witch produces 400 frames! Glxinfo says something like "RGB
error" and breaks.
There's no support for the AGP bus mastering on PowerMac yet. I've been
running into trouble implementing that due to differences between what
the linux /dev/agpgart driver expect an AGP chipset to do, and what
Apple's UniNorth can actually do.

I plan (this week-end) to look more closely at the r128 DRI code to see
how it uses the AGP and possibly implement a pmac-specific driver (at
least for now. Once I have working code, I can try to get the existing /
dev/agpgart driver redesigned).

Ben.
