Hi All,
Have just started looking into the xserver code and is a spare time
project of mine. Would be great if someone can answer the following
basic questions.
The DDX video driver module loaded into the xserver talks to the
DRM for its functionality.
a. What happens when the vid

Some of them do, but not all of them.

Thanks Alan and Adam for the replies.
Have another related question:
i want to build a software based 3D and 2D renderer system with DRI with the
following.
a. I dont wish to use the GPU for 3D or 2D acceleration (so dont want to use
the 3D/2D driver of my GPU). Instead, want to use the dummy dri

pretty much what you get if you just load vesa driver.
it should use swrast for all GLX.

Hi Dave,
Thanks for the reply.
a) Are you suggesting that Vesa always uses swrast for 3D rendering? Was
reading some articles on the net and it seems like vesa driver can be
used with a DRI based 3D Hardware driver also. Would really appreciate
if you could elaborate here a little.
b) Assuming

VESA drives a hardware graphics device, using the least common denominator
VESA standard - you'll see its output on your monitor. Dummy just allocates
some virtual memory and draws pic

So you want to use the DRI to get direct hardware access...
