dri status? (agpgart?)

dri status? (agpgart?)

[Steven Hanley]

All

I am just now grabbing the cvs repository from dri.sourceforge.net to see if
I can get dri running on my pismo, now I am wondering what the current
status is?

(I am of course doing this because gareth hughs was at linux.conf.au over
the last few days, and I was completely blown away by the performance of 3d
stuff on his laptop (it was absolutely amazing to say the least))

Last I heard for ppc was that we could do dri but not the agpgart stuff,
which means it doesnt go quite as fast as we may wish (no mtrr write
combining or some such) but it does handle stuff like complex textures and
such damn nicely. Is this still the case?

Anyway I suppose I will find out in a while what it works like on the pismo
currently.

	See You

Yes, it will rock once it works. :)

That was about the situation a few months ago. Currently, the r128 DRI doesn't
work without AGP GART.

PCI GART support is currently being developed in a branch of the DRI CVS, but
I haven't got it to work on my Pismo yet (see the other thread about 'PPC
lockups'). As always, any help is much appreciated! :)

As for AGP GART, once PCI GART works I may have a stab at that. But I don't
expect it to give a substantial performance boost.

This is an ia32 thing and doesn't affect us.
