-# Makefile -- For the Direct Rendering Manager module (drm)
-#
-# Based on David Woodhouse's mtd build.
-#
-# Modified to handle the DRM requirements and builds on a wider range of
-# platforms in a flexible way by David Dawes. It's not clear, however,
-# that this approach is simpler than the old one.
-#
-# The purpose of this Makefile is to handle setting up everything
-# needed for an out-of-kernel source build. Makefile.kernel contains
-# everything required for in-kernel source builds. It is included into
-# this file, so none of that should be duplicated here.
-#
-# $XFree86: xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel/Makefile.linux,v 1.40 2003/08/17 17:12:25 dawes Exp $

-#
-# By default, the build is done against the running linux kernel source.
-# To build against a different kernel source tree, set LINUXDIR:
-#
-# make LINUXDIR=/path/to/kernel/source
-
-#
-# To build only some modules, either set DRM_MODULES to the list of modules,
-# or specify the modules as targets:
-#
-# make r128.o radeon.o

-************************************************************
-
-The Direct Rendering Manager (drm) is a device-independent kernel-level
-device driver that provides support for the XFree86 Direct Rendering
-Infrastructure (DRI).
-
-The DRM supports the Direct Rendering Infrastructure (DRI) in four major
-ways:
-
- 1. The DRM provides synchronized access to the graphics hardware via
- the use of an optimized two-tiered lock.
-
- 2. The DRM enforces the DRI security policy for access to the graphics
- hardware by only allowing authenticated X11 clients access to
- restricted regions of memory.
-
- 3. The DRM provides a generic DMA engine, complete with multiple
- queues and the ability to detect the need for an OpenGL context
- switch.
-
- 4. The DRM is extensible via the use of small device-specific modules
- that rely extensively on the API exported by the DRM module.
-
-
-Documentation on the DRI is available from:
- http://precisioninsight.com/piinsights.html
-
-For specific information about kernel-level support, see:
-
- The Direct Rendering Manager, Kernel Support for the Direct Rendering
- Infrastructure
