<title>VMware guest GL driver</title>

<h1>VMware guest GL driver</h1>
<p>
This page describes how to build, install and use the VMware guest GL driver
(aka the SVGA or SVGA3D driver) for Linux using the latest source code.
This driver gives a Linux virtual machine access to the host's GPU for
hardware-accelerated 3D.
VMware Workstation running on Linux or Windows and VMware Fusion running on
MacOS are all supported.
</p>
<p>
End users shouldn't have to go through all these steps once the driver is
included in newer Linux distributions.
</p>
<p>
For more information about the X components see these wiki pages at x.org:

Driver Overview</a>
<li><a href="http://wiki.x.org/wiki/vmware/vmware3D" target="_parent">
xf86-video-vmware Details</a>
</ul>
<h2>Components</h2>
The components involved in this include:
<ul>
<li>Linux kernel module: vmwgfx
<li>X server 2D driver: xf86-video-vmware
<li>User-space libdrm library
<li>Mesa/gallium OpenGL driver: "svga"
</ul>
<h2>Prerequisites</h2>
<ul>
<li>Kernel version at least 2.6.25
<li>Xserver version at least 1.7
<li>Ubuntu: For ubuntu you need to install a number of build dependencies.
<pre>
sudo apt-get install git-core
sudo apt-get install automake libtool libpthread-stubs0-dev
sudo apt-get install xserver-xorg-dev x11proto-xinerama-dev
sudo apt-get build-dep libgl1-mesa-dri libxcb-glx0-dev
</pre>
<li>Fedora: For Fedora you also need to install a number of build dependencies.
<pre>
sudo yum install mesa-libGL-devel xorg-x11-server-devel xorg-x11-util-macros
sudo yum install automake gcc libtool expat-devel kernel-devel git-core
</pre>
</ul>
<p>
Depending on your Linux distro, other packages may be needed.
The configure scripts should tell you what's missing.
</p>
<h2>Getting the Latest Source Code</h2>
Begin by saving your current directory location:
<pre>
export TOP=$PWD
</pre>
<ul>
<li>Mesa/Gallium master branch. This code is used to build libGL, and the direct rendering svga driver for libGL, vmwgfx_dri.so, and the X acceleration library libxatracker.so.x.x.x.
<pre>
git clone git://anongit.freedesktop.org/git/mesa/mesa
</pre>
<li>VMware Linux guest kernel module. Note that this repo contains the complete DRM and TTM code. The vmware-specific driver is really only the files prefixed with vmwgfx.
<pre>
git clone git://anongit.freedesktop.org/git/mesa/vmwgfx
</pre>
<li>libdrm, A user-space library that interfaces with drm. Most distros ship with this driver. Safest bet is really to replace the system one. Optionally you can point LIBDRM_CFLAGS and LIBDRM_LIBS to the libdrm-2.4.22 package in toolchain. But here, we replace:
<pre>
git clone git://anongit.freedesktop.org/git/mesa/drm
</pre>
<li>xf86-video-vmware. The chainloading driver, vmware_drv.so, the legacy driver vmwlegacy_drv.so, and the vmwgfx driver vmwgfx_drv.so.
<pre>
git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-vmware
</pre>
</ul>
<h2>Building the Code</h2>
<ul>
<li>Build libdrm: If you're on a 32-bit system, you should skip the --libdir configure option. Note also the comment about toolchain libdrm above.
<pre>
cd $TOP/drm
./autogen.sh --prefix=/usr --enable-vmwgfx-experimental-api --libdir=/usr/lib64
make
sudo make install
</pre>
<li>Build Mesa and the vmwgfx_dri.so driver, the vmwgfx_drv.so xorg driver, the X acceleration library libxatracker.
The vmwgfx_dri.so is used by the OpenGL libraries during direct rendering,
and by the Xorg server during accelerated indirect GL rendering.
The libxatracker library is used exclusively by the X server to do render,
copy and video acceleration:
<br>
The following configure options doesn't build the EGL system.
<br>
As before, if you're on a 32-bit system, you should skip the --libdir
configure option.
<pre>
cd $TOP/mesa
./autogen.sh --prefix=/usr --libdir=/usr/lib64 --with-gallium-drivers=svga --with-dri-drivers= --enable-xa
make
sudo make install
</pre>
Note that you may have to install other packages that Mesa depends upon
if they're not installed in your system. You should be told what's missing.
<br>
<br>
<li>xf86-video-vmware: Now, once libxatracker is installed, we proceed with building and replacing the current Xorg driver. First check if your system is 32- or 64-bit. If you're building for a 32-bit system, you will not be needing the --libdir=/usr/lib64 option to autogen.
<pre>
cd $TOP/xf86-video-vmware
./autogen.sh --prefix=/usr --libdir=/usr/lib64
make
sudo make install
</pre>
<li>vmwgfx kernel module. First make sure that any old version of this kernel module is removed from the system by issuing
<pre>
sudo rm /lib/modules/`uname -r`/kernel/drivers/gpu/drm/vmwgfx.ko*
</pre>
Then
<pre>
cd $TOP/vmwgfx
make
sudo make install
sudo cp 00-vmwgfx.rules /etc/udev/rules.d
sudo depmod -ae
</pre>
</ul>
Now try to load the kernel module by issuing
<pre>
sudo modprobe vmwgfx</pre>
Then type
<pre>
dmesg</pre>
to watch the debug output. It should contain a number of lines prefixed with "[vmwgfx]".
<p>
Then restart the Xserver (or reboot).
The lines starting with "vmwlegacy" or "VMWARE" in the file /var/log/Xorg.0.log
should now have been replaced with lines starting with "vmwgfx", indicating that
the new Xorg driver is in use.
</p>
<h2>Running OpenGL Programs</h2>
<p>
In a shell, run 'glxinfo' and look for the following to verify that the
driver is working:
</p>
<pre>
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on SVGA3D; build: RELEASE;
OpenGL version string: 2.1 Mesa 8.0
</pre>
If you don't see this, try setting this environment variable:
<pre>
export LIBGL_DEBUG=verbose</pre>
then rerun glxinfo and examine the output for error messages.
