<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>

103

104

<ul>

105

<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.

106

<pre>

107

cd $TOP/drm

108

./autogen.sh --prefix=/usr --enable-vmwgfx-experimental-api --libdir=/usr/lib64

109

make

110

sudo make install

111

</pre>

112

<li>Build Mesa and the vmwgfx_dri.so driver, the vmwgfx_drv.so xorg driver, the X acceleration library libxatracker.

113

The vmwgfx_dri.so is used by the OpenGL libraries during direct rendering,

114

and by the Xorg server during accelerated indirect GL rendering.

115

The libxatracker library is used exclusively by the X server to do render,

116

copy and video acceleration:

117

<br>

118

The following configure options doesn't build the EGL system.

119

<br>

120

As before, if you're on a 32-bit system, you should skip the --libdir

121

configure option.

122

<pre>

123

cd $TOP/mesa

124

./autogen.sh --prefix=/usr --libdir=/usr/lib64 --with-gallium-drivers=svga --with-dri-drivers= --enable-xa

125

make

126

sudo make install

127

</pre>

128

129

Note that you may have to install other packages that Mesa depends upon

130

if they're not installed in your system. You should be told what's missing.

131

<br>

132

<br>

133

134

<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.

135

<pre>

136

cd $TOP/xf86-video-vmware

137

./autogen.sh --prefix=/usr --libdir=/usr/lib64

138

make

139

sudo make install

140

</pre>

141

<li>vmwgfx kernel module. First make sure that any old version of this kernel module is removed from the system by issuing

142

<pre>

143

sudo rm /lib/modules/`uname -r`/kernel/drivers/gpu/drm/vmwgfx.ko*

144

</pre>

145

Then

146

<pre>

147

cd $TOP/vmwgfx

148

make

149

sudo make install

150

sudo cp 00-vmwgfx.rules /etc/udev/rules.d

151

sudo depmod -ae

152

</pre>

153

</ul>

154

155

156

Now try to load the kernel module by issuing

157

<pre>

158

sudo modprobe vmwgfx</pre>

159

Then type

160

<pre>

161

dmesg</pre>

162

to watch the debug output. It should contain a number of lines prefixed with "[vmwgfx]".

163

164

<p>

165

Then restart the Xserver (or reboot).

166

The lines starting with "vmwlegacy" or "VMWARE" in the file /var/log/Xorg.0.log

167

should now have been replaced with lines starting with "vmwgfx", indicating that

168

the new Xorg driver is in use.

169

</p>

172

<h2>Running OpenGL Programs</h2>

173

174

<p>

175

In a shell, run 'glxinfo' and look for the following to verify that the

176

driver is working:

177

</p>

178

179

<pre>

180

OpenGL vendor string: VMware, Inc.

181

OpenGL renderer string: Gallium 0.4 on SVGA3D; build: RELEASE;

182

OpenGL version string: 2.1 Mesa 8.0

183

</pre>

184

185

If you don't see this, try setting this environment variable:

186

<pre>

187

export LIBGL_DEBUG=verbose</pre>

188

then rerun glxinfo and examine the output for error messages.
