From 1bf0d869ae07ffc5b9cd79904b421cd37997ae8c Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 17 Apr 2013 15:24:10 +0100 Subject: Prefer i830_dri.so for gen2 chipsets Probe for i830_dri.so and, if it exists, use that driver in preference to i915_dri.so for DRI (i.e. GL clients). This was suggested in the context of distributions supplying i915g as the main DRI driver for gen3, in which case we need to provide a separate DRI driver for gen2.
