+===== Preface =====
+ * This page will guide you to get support of Mali X11 3D acceleration.
+ * You'll be able to test all the aspects of a Embedded System OpenGL|ES implementation.
+===== Pre-requisite =====
+===== Ubuntu Version =====
+ * To get the Mali support working you'll need Ubuntu 9-Feb image and upwards.
+ * Check below the Download link for your board.
+==== ODROID-X ====
+ * http://forum.odroid.com/viewtopic.php?f=22&t=28
+==== ODROID-X2 ====
+ * http://forum.odroid.com/viewtopic.php?f=15&t=27
+==== ODROID-U2 ====
+ * http://forum.odroid.com/viewtopic.php?f=8&t=12
+===== Development Libs =====
+ * All the needed development files can be installed with the command below:
+ * sudo apt-get install libjpeg-dev libpng12-dev libx11-dev libglu1-mesa-dev subversion build-essential autoconf automake make libtool xorg-dev xutils-dev libdrm-dev libdri2-1 libdri2-dev git libglew1.6 libglew1.6-dev
+===== Speed test : Mesa Software rendering vs Mali400 Hardware rendering =====
+ * Before installing or doing anything on your stock image. I welcome you to test the difference between software and hardware.
+ * Let's start Mali 3D driven glmark2-es2.
+ * Open a terminal (Ctrl-Alt-t)
+ * Install : sudo apt-get install glmark2-es2
+ * Run: glmark2-es2
+<code>

+ * Mali 3D accelerator is roughly 35 times faster!
+This is the screen shot of glmark2.

+ * 3D rendering performance is significantly affected by desktop of Linux. These are the score of glmark2-es2.
+    * Unity : 70 pts
+    * xfce : 110 pts
+    * lxde : 140 pts
+* You can download the full source code of glmark-es2, if you want.
+<code>
+ apt-get source glmark2-es
+</code>
+===== Mali MP400-4 Specs =====
+The Mali MP400 GPU on the your ODROID (X/X2/U2/U) board has:
+  * 256KiB of L2 Cache
+  * 4 GPU Cores (Known as PP)
+  * Can Support OpenGL ES 1.1 and OpenGL ES 2.0
+  * Full compliance with Khronos OpenGL ES 1.1/2.0 API
+  * FSAA (Full Scene Anti Aliasing)
+  * High Working frequency (440Mhz for ODROID-X/U and 533Mhz for ODROID-X2/U2)
+  * Overclock Capabilities
+  * 4xAA Multi-sampling with almost no performance drop
+  * 16xAA outperforming all implementations of comparable quality
+The kernel source code is fully GPL open source.
+User land X11 3D libaries are IP of ARM and those are closed source.
+===== Building Mesa Demos from Source =====
+ - Make sure you have passed the dependencies and Mali drivers without issues.
+ - Download mesa-demos sources
+<code>
+git clone --depth 1 git://anongit.freedesktop.org/mesa/demos
+</code>
+ - Build it using:
+<code>
+  ./autogen.sh
+  make
+</code>
+ - Under the src folder, you'll find a lot of examples including the folder opengles2, with es2gears_x11, s2tri and es2_info. Also you'll find alot of OpenGL and Software Rasterizer sinde.
+===== OpenGL ES Book Samples =====
+ - Make sure you have passed the dependencies and Mali drivers without issues.
+ - Download sources using:
+ * svn checkout http://opengles-book-samples.googlecode.com/svn/trunk/ opengles-book-samples-read-only
+ - Build using:
+<code>
+$cd opengles-book-samples-read-only/LinuxX11
+$make
+</code>
+ - Check the Chapter_* folders, You'll find the built in programs as well their sources
+ * You can find more information of this book as well it on the References part of this page
+===== Other OpenGL ES Applications =====
+There are other OpenGL ES application that can be tried on the platform.
+<code>
+$apt-cache search "OpenGL ES"
+</code>
+The command above will show you few application written for OpenGL ES
+A good testing application will be glmark2-es2. Install it using:
+<code>
+$apt-get install glmark2-es2
+</code>
+===== For Developers =====
+ * For developers compiling their own application above is listed the CFLAGS and Linker Flags to use Mali:
+ - CFLAGS: -I/usr/include/EGL -I/usr/include/GLES -I/usr/include/GLES2 -I/usr/include/KHR
+ - Linker: -lEGL -lGLES -LGLES2
+===== Known Issues =====
+ * Unity3D Known to be buggy on Standard OpenGL ES. A fix waited.
+ * Compiz wraps OpenGL content into OpenGL ES causing heavy instabilities as well frame rate dropping.
+ * XBMC, the present version of XBMC inside Linaro's repo, is old and doesn't support the Exynos MFC, so its software decoding everything. Its known that a team of developers is fixing XBMC on Linux to build again over X11 GLES. This wiki will be update as soon as we heard from them.
