vmsock - vmware kernel module SYNOPSIS
modprobe vmsock DESCRIPTION
This is a Linux kernel device driver module that provides datagram and stream socket interfaces to the underlying VMCI device. The module implements a Linux socket family and one of the files in the module, vmci_sockets.h, provides the various constants and functions necessary to create and, in the case of streams, connect sockets. When the module is loaded, /dev/vsock will be created with restricted permissions. Access to /dev/vsock is required to use VMCI sockets, so it's recommended that permissions be relaxed via a udev policy file. For reference, the VMware Tools init script changes the permissions of /dev/vsock to 666. Normally, issuing a socket(2) system call will automatically load the kernel module providing that socket family, but as the vsock module is out-of-tree, there is no in-tree socket family reservation for VMCI sockets. Before sockets are created, userspace applications must call VMCISock_GetAFValue (defined in vmci_sockets.h) which will instruct the vsock module to dynamically acquire a socket family reserva- tion from the kernel. This function is implemented via ioctl(2) into the vsock module, so the vsock module must be manually loaded by the user (perhaps using /etc/modules). The vmci_sockets.h header should be installed in a system-wide location. We recommend /usr/include/vmci. The vsock module depends on symbols from the vmci module, and so the vmci module must be loaded first. OPTIONS
vmsock has no options. SEE ALSO

VMWARE(4) Kernel Interfaces Manual VMWARE(4) NAME
vmware - VMware SVGA video driver SYNOPSIS
Section "Device" Identifier "devname" Driver "vmware" ... EndSection DESCRIPTION
vmware is an Xorg driver for VMware virtual video cards. MODESETTING, XINERAMA AND RANDR12 If the driver can connect to the "vmwgfx" kernel module on linux, it will attempt to use kernel modesetting and will then also use RandR12 for multiple output operation instead of Xinerama. The X server log or the "xrandr" application can be used to determine whether RandR12 or Xinerama is actually used. 3D ACCELERATION If the driver can connect to the "vmwgfx" kernel module on linux, and the Virtual Machine is set up to use 3D acceleration, the driver will try to use Gallium3D XA to accelerate 3D operations. It will also by default enable DRI, the Direct Rendering Infrastructure, primarily for accelerated OpenGL. If 3D acceleration is available, the driver will in addition provide an additional XVideo adaptor for textured video. Gallium3D XA,ibxatracker.so" and the accelerated OpenGL driver, "vmwgfx_dri.so" is provided by the mesa distribution. CONFIGURATION DETAILS
Please refer to xorg.conf(5) for general configuration details. This section only covers configuration details specific to this driver. The driver auto-detects the version of any virtual VMware SVGA adapter. The following driver Options are supported: Option "HWCursor" "boolean" Enable or disable the HW cursor. Default: off. Option "Xinerama" "boolean" Disable or enable Xinerama support. Default: xinerama is enabled if the hardware supports it. Option "StaticXinerama" "string" Provide a static xinerama geometry that will be active at server startup and will not be overridden at runtime. The format is "Width1xHeight1+Xoffset1+Yoffset1;Width2xHeight2+Xoffset2+Yoffset2" and so on. Negative offsets are not supported. If the driver is using RandR12, this option should be used to place and enable outputs at driver startup time or else when VMware tools is not used for that purpose. Also please see option "GuiLayout". Option "GuiLayout" "string" A synonym to option "StaticXinerama", since the latter name is somewhat misleading when RandR12 is favoured before Xinerarma. Option "AddDefaultMode" "boolean" Provide a default mode with a resolution identical to the resolution of the guest before the X server was started. The X server will thus try to start without changing resolution. Default: on. Option "RenderAccel" "boolean" Try to accelerate render operations if the operations are reading from previously accelerated contents (3D or video). This option is needed for 3D support. Default: on if 3D acceleration is supported. Otherwise off. Option "DRI" "boolean" Enable the Direct Rendering Infrastructure. Default: on if 3D acceleration is supported and "RenderAccel" is enabled. Otherwise off. Option "DirectPresents" "boolean" Speed up OpenGL swapbuffers by skipping a copy operation. This provides some OpenGL swapbuffer speedups, but may cause performance degradation and rendering errors when 3D contents is read back for mixing with software rendered contents. Default: off. Option "HwPresents" "boolean" This is a developer convenience option and should not be used by distros or normal users. When enabled, it copies software rendered contents to a 3D surface before presenting it, so that the visible screen is always present on a 3D surface. Default: off. Option "RenderCheck" "boolean" This is a developer convenience option and should not be used by distros or normal users. When enabled, it tries to use 3D accelera- tion for all XRender operations where 3D acceleration is supported, resulting in a considerable slowdown due to the increased number of readbacks of accelerated contents from host to guest. This option is used to verify that the accelerated Xrender paths works cor- rectly with the "rendercheck" application. Default: off.
