VMware guest GL driver

+ +

+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. +

+ +

+End users shouldn't have to go through all these steps once the driver is +included in newer Linux distributions. +

+ + + +

Components

+ +The components involved in this include: +

Linux kernel module: vmwgfx +
X server 2D driver: xf86-video-vmware +
User-space libdrm library +
Mesa/gallium OpenGL driver: "svga" +

+ + +

Prerequisites

+ +

Kernel version at least 2.6.25 +
Xserver version at least 1.7 +

Ubuntu: For ubuntu you need to install a number of build dependencies. +

+  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
+

Fedora: For Fedora you also need to install a number of build dependencies. +

+  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
+

+ +

+Depending on your Linux distro, other packages may be needed. +The configure scripts should tell you what's missing. +

+ + + +

Getting the Latest Source Code

+ +Begin by saving your current directory location: +

+  export TOP=$PWD
+

+ +

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. +
```
+  git clone git://anongit.freedesktop.org/git/mesa/mesa
+  
```
+
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. +
```
+  git clone git://anongit.freedesktop.org/git/mesa/vmwgfx
+  
```
+ +
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: +
```
+  git clone git://anongit.freedesktop.org/git/mesa/drm
+  
```
+
xf86-video-vmware. The chainloading driver, vmware_drv.so, the legacy driver vmwlegacy_drv.so, and the vmwgfx driver vmwgfx_drv.so. +
```
+  git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-vmware
+  
```
+

+ + +

Building the Code

+ +

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. +
```
+  cd $TOP/drm
+  ./autogen.sh --prefix=/usr --enable-vmwgfx-experimental-api --libdir=/usr/lib64
+  make
+  sudo make install
+  
```
+
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: +
+The following configure options doesn't build the EGL system. +
+As before, if you're on a 32-bit system, you should skip the --libdir +configure option. +
```
+  cd $TOP/mesa
+  ./autogen.sh --prefix=/usr --libdir=/usr/lib64 --with-gallium-drivers=svga --with-dri-drivers= --enable-xa
+  make
+  sudo make install
+  
```
+ +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. +
+
+ +
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. +
```
+  cd $TOP/xf86-video-vmware
+  ./autogen.sh --prefix=/usr --libdir=/usr/lib64
+  make
+  sudo make install
+  
```
+

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

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

+Then +

+  cd $TOP/vmwgfx
+  make
+  sudo make install
+  sudo cp 00-vmwgfx.rules /etc/udev/rules.d
+  sudo depmod -ae
+

+ + +Now try to load the kernel module by issuing +

+  sudo modprobe vmwgfx

+Then type +

+  dmesg

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

+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. +

+ + +

Running OpenGL Programs

+ +

+In a shell, run 'glxinfo' and look for the following to verify that the +driver is working: +

+ +

+OpenGL vendor string: VMware, Inc.
+OpenGL renderer string: Gallium 0.4 on SVGA3D; build: RELEASE;
+OpenGL version string: 2.1 Mesa 8.0
+

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

+  export LIBGL_DEBUG=verbose

+then rerun glxinfo and examine the output for error messages. +

+ + + + + -- 2.30.2
