DRI - VIA - CLE266

[Gregoire Gentil]

Hello,

I'm trying to use DRI on a VIA Chipset (CLE266) with 256MB of Ram. I
have compiled and installed via_drv.so from unichrome.sf.net (latest
version as of 5/31/2006). I have also compiled and installed
unichrome_dri.so, libGL.so.1.2 and libGLU.so.1.3.060500 from MesaLib6.5
(latest version as of 5/31/2006). I have the following drirc file:

<driconf>
    <device screen="0" driver="unichrome">
        <application name="all">
        </application>
    </device>
</driconf>

A glxinfo returns:

(WW) VIA(0): [drm] Not using DMA for copying to FB (drm driver older

(II) VIA(0): Using XFree86 Acceleration Architecture (XAA)

I have the latest Ubuntu kernel available: 2.6.15-23.

What can I make DRI work? Is it the problem with DMA?

Thanks by advance for your answer,

Gregoire
