X Strike Force X.Org X11 SVN commit: r4114 - branches/experimental/xserver/xorg-server/hw/xfree86/os-support
Author: beatle
Date: 2006-12-02 07:20:54 -0500 (Sat, 02 Dec 2006)
New Revision: 4114
Removed:
branches/experimental/xserver/xorg-server/hw/xfree86/os-support/drm/
branches/experimental/xserver/xorg-server/hw/xfree86/os-support/xf86drm.h
Log:
Remove the drm subdirectory and xf86drm.h include file which are no longer
provided upstream. The X server now uses the system libdrm.
Deleted: branches/experimental/xserver/xorg-server/hw/xfree86/os-support/xf86drm.h
