Introduction</h1> - -<p> -The fbdev/DRI environment supports hardware-accelerated 3D rendering without -the X window system. This is typically used for embedded applications. -</p> - -<p> -Contributors to this project include Jon Smirl, Keith Whitwell and Dave Airlie. -</p> - -<p> -Applications in the fbdev/DRI environment use -the MiniGLX interface to choose pixel -formats, create rendering contexts, etc. It's a subset of the GLX and -Xlib interfaces allowing some degree of application portability between -the X and X-less environments. -</p> - -<p> -Note that this environment is not well-supported and these instructions -may not be completely up to date. -</p> -<br> - - - -<h1>2. Compilation</h1> -<p> - -<h2>2.1 glxproto</h2> - -Get <a href="http://cvsweb.xfree86.org/cvsweb/*checkout*/xc/include/GL/glxproto.h?rev=1.9">glxproto.h</a>. Copy it to the /mesa/include/GL/ directory. -</p> - -<h2>2.2 libpciaccess</h2> -<p> -Check if you have libpciaccess installed: -</p> - -<pre>pkg-config --modversion pciaccess -</pre> -<p> -If not you can download the latest code from: -</p> -<pre> git clone git://anongit.freedesktop.org/git/xorg/lib/libpciaccess -</pre> -<p> -Run autogen.sh to generate a configure file. autogen.sh uses autoconf -utility. This utility may not be installed with your linux distro, -check if it is available. if not you can use your package manager or -type: -</p> -<pre>sudo apt-get install autoconf -</pre> -The next step is to install the libpciaccess library. -<pre>make -make install -</pre> -<p> Now your libpciaccess.a file is saved into /usr/local/lib -directory. If you have a libpciaccess.a in /usr/lib you may simply copy -and overwrite these files. Don't forget to copy libpciaccess.pc file to -/usr/lib/pkgconfig, which is also located in /usr/local/lib/pkgconfig/. -Or you may use the following system variables: -</p> -<pre>export LD_LIBRARY_PATH=/usr/local/lib -export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig -</pre> - -<h2>2.3 drm</h2> - -<p>The next step is to compile the drm. DRM consists of two seperate parts, -the DRM client library(lindrm.so) and kernel device module(such as -radeon.ko). We need to make a small change in kernel device module. So -you need to download the kernel source. You may choose the nearest -mirror from www.kernel.org, or you are using Fedora Core 5, for -example, you may need to install RPMs such as: -kernel-smp-devel-2.16.15-1.2054_FC5.i686.rpm -kernel-devel-2.6.15-1.2054_FC5.i686.rpm -etc. You can find a detailed information <a href="http://www.howtoforge.com/kernel_compilation_fedora">here.</a> -</p> - -<p>You will find drm_drv.c at /usr/src/LINUX-VERSION/drivers/char/drm/. Edit this code and comment out the following part: -</p> - -<pre> - /* || - ((ioctl->flags & DRM_MASTER) && !priv->master)*/ -</pre> -Now you are ready to compile your kernel. If your kernel version is -identical to the version you have compiled, you can simply over write -your new "ko" files over older ones. If you have compiled a different -kernel, you must configure your grub or lilo to be able to boot your -new kernel. <p> -You'll need fbdev header files. Check with: -</p> -<pre> - ls -l /usr/include/linux/fb. -</pre> -<p>This file may be missing if you have not installed linux header files. - - -<h2>2.4 Mesa</h2> - -</p><p>Get latest development Mesa sources from git repository -(currently 7.1-prerelease) -</p> -<pre> - git clone git://anongit.freedesktop.org/git/mesa/mesa -</pre> - -<p>You will need the makedepend utility which is a part of mesa project -to build your linux-solo. You probably wont have this utility. You can -download its source from following git repulsitory: -</p> -<pre> - git clone git://anongit.freedesktop.org/git/xorg/util/makedepend -</pre> - -<p>Get the latest stable mesa version from SourceForge (currently 7.0.3) -<a href="http://sourceforge.net/project/showfiles.php?group_id=3">http://sourceforge.net/project/showfiles.php?group_id=3</a> -</p> - -<p>Copy the miniglx folder from 7.1-prerelease to 7.0.3. -You may also extract GLUT to 7.0.3 version at this step. -</p> - -<p>Edit linux-solo.conf at /conf directory, just only compile the -graphics driver you need, delete the unwanted drivers names from the -list(some drivers are causing problems...) -</p> -<pre> - while(build==0) - { - make linux-solo - - There will be some missing header files, copy them from 7.1-prerelease - } -</pre> - -<p> -When complete you should have the following: -</p> -<ul> -<li>lib/libGL.so - the GL library which applications link with -</li><li>lib/*_dri_so - DRI drivers -</li><li>lib/miniglx.conf - sample MiniGLX config file -</li><li>progs/miniglx/* - several MiniGLX sample programs -</li></ul> - -To install these files into appropriate locations in system: -<pre> - make install -</pre> - -Now your openGL libraries are copied to /usr/local/lib and -miniglx.conf is copied to /etc. You may copy them to /usr/lib and -overwrite your old GL libraries. Or you may export following variable: - -<pre> - export LIBGL_DRIVERS_PATH=/usr/local/lib -</pre> -<br> - - -<h1>3. Using fbdev/DRI</h1> - -<p> -If an X server currently running, exit/stop it so you're working from -the console. Following command shuts down the x window and also the multi user support. -</p> -<pre> - init 1 -</pre> - -<p>Also you may define the runlevel as 1 in "/etc/inittab". Your system -will always start in single user mode and without x-window with this -option set. -</p><h2>3.1 Load Kernel Modules</h2> - -<p> -You'll need to load the kernel modules specific to your graphics hardware. -Typically, this consists of the agpgart module, an fbdev driver module -and the DRM kernel module. -</p> -<p> -As root, the kernel modules can be loaded as follows: -</p> - -<p> -If you have Intel i915/i945 hardware: -</p> -<pre> modprobe agpgart # the AGP GART module - modprobe intelfb # the Intel fbdev driver - modprobe i915 # the i915/945 DRI kernel module -</pre> - -<p> -If you have ATI Radeon/R200 hardware: -</p> -<pre> modprobe agpgart # the AGP GART module - modprobe radeonfb # the Radeon fbdev driver - modprobe radeon # the Radeon DRI kernel module -</pre> - -<p> -If you have ATI Rage 128 hardware: -</p> -<pre> modprobe agpgart # the AGP GART module - modprobe aty128fb # the Rage 128 fbdev driver - modprobe r128 # the Rage 128 DRI kernel module -</pre> - -<p> -If you have Matrox G200/G400 hardware: -</p> -<pre> modprobe agpgart # the AGP GART module - modprobe mgafb # the Matrox fbdev driver - modprobe mga # the Matrox DRI kernel module -</pre> - -<p> -To verify that the agpgart, fbdev and drm modules are loaded: -</p> -<pre> ls -l /dev/agpgart /dev/fb* /dev/dri -</pre> -<p> -Alternately, use lsmod to inspect the currently installed modules. -If you have problems, look at the output of dmesg. -</p> - - -<h2>3.2 Configuration File</h2> - -<p> -review/edit /etc/miniglx.conf. -Alternately, the MINIGLX_CONF environment variable can be used to -indicate the location of miniglx.conf -</p> - -To determine the pciBusID value, run lspci and examine the output. -For example: -<p></p> -<pre> /sbin/lspci: - 00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Express Chipset Family Graphics Controller (rev 04) -</pre> -<p> -00:02.0 indicates that pciBusID should be PCI:0:2:0 -</p> - - - - -<h2>3.3 Running fbdev/DRI Programs</h2> - -<p> -Make sure your LD_LIBRARY_PATH environment variable is set to the -location of the libGL.so library. You may need to append other paths -to LD_LIBRARY_PATH if libpciaccess.so is in a non-standard location, -for example. -</p> - -<p> -Change to the <code>Mesa/progs/miniglx/</code> directory and -start the sample_server program in the background: -</p> -<pre> ./sample_server & -</pre> - -<p> -Then try running the <code>miniglxtest</code> program: -</p> -<pre> ./miniglxtest -</pre> -<p> -You should see a rotating quadrilateral which changes color as it rotates. -It will exit automatically after a bit. -</p> - -<p> -If you run other tests in the miniglx/ directory, you may want to run -them from a remote shell so that you can stop them with ctrl-C. -</p> -<br> - - -<h1>4.0 Troubleshooting</h1> - -<ol> -<li> -If you try to run miniglxtest and get the following: -<br> -<pre> [miniglx] failed to probe chipset - connect: Connection refused - server connection lost -</pre> -It means that the sample_server process is not running. -<br> -<br> -</li> -</ol> - - -<h1>5.0 Programming Information</h1> - -<p> -OpenGL/Mesa is interfaced to fbdev via the MiniGLX interface. -MiniGLX is a subset of Xlib and GLX API functions which provides just -enough functionality to setup OpenGL rendering and respond to simple -input events. -</p> - -<p> -Since MiniGLX is a subset of the usual Xlib and GLX APIs, programs written -to the MiniGLX API can also be run on full Xlib/GLX implementations. -This allows some degree of flexibility for software development and testing. -</p> - -<p> -However, the MiniGLX API is not binary-compatible with full Xlib/GLX. -Some of the structures are different and some macros/functions work -differently. -See the GL/miniglx.h header file for details. -</p> - - - -</body> -</html> |
