From 29ca7d2c9488d13e496ec65b6e1e1bf1d53042c5 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Tue, 17 Jun 2014 14:34:52 +0100 Subject: st/dri: merge dri/drm and dri/sw backends Move the driver_name to dri2/drisw and remove all the SPLIT_TAGETS mayhem. In the next step we'll unify the dri and dri-swrast targets, completing the gallium DRI megadriver. v2: Remove leftover st/dri Makefiles from CONFIG_FILES. Spotted by Thomas Helland.
