Subject: [Linux-ia64] complete fixes for DRI/DRM
From: David Mosberger <davidm () hpl ! hp ! com>
Date: 2000-08-18 7:33:09
[Download RAW message or body]
The patch below is a superset of what I just sent to the
fixes@xfree86.org list. It include the config changes necessary to
get the GL/DRI/TDFX support built.
The way this config is setup, you'll get the DRI drivers built into
libGl instead of having them as separate modules. I didn't try
building them as modules, though I hope it would work just fine.
