Description Jaime 2006-09-07 10:43:20 UTC

Hi.

This is just a request for an enhancement: I'd like the DRI driver for the
built-in savage chip (an S3 Inc. 86C270-294 Savage/IX-MV) on my IBM T21 laptop
to use AGP memory (rather than local video RAM) for the back-buffer and
depth-buffer.

I think MS Windows 2000 can do this, because I can get DRI on Windows at
24-32bpp at 1400x1050 resolution, whereas xorg cannot do this (it reports:
"xxxx kB of Videoram needed for 3D; 8192 kB of Videoram available", where
xxxx is greater than 8192).

I asked about this subject on the dri-users mailing list, and this RFE is
just a paraphrasing of the explanation that Roland Scheidegger kindly gave
me - you can find the archive of the conversation here:

Many thanks.
