wsfb - video driver for wsdisplay framebuffer device
Section "Device" Identifier "devname" Driver "wsfb" ... EndSection
wsfb is an XFree86 driver for the OpenBSD wsdisplay frame- buffer devices. This is a non-accelerated driver. The fol- lowing framebuffer depths are supported: 1, 8, 16 and 24, given that the wsdisplay device underneath supports them. A StaticGray monochrome visual is provided for depth 1, all visual types are supported for depth 8 and a TrueColor visual is supported for the other depths. Multi-head confi- gurations are supported.
The wsfb driver supports all hardware where a wsdisplay framebuffer driver is available on OpenBSD. Currently this includes OpenBSD/macppc, OpenBSD/sparc, OpenBSD/sparc64 and OpenBSD/alpha on TGA graphics cards.
Please refer to XF86Config(5) for general configuration details. This section only covers configuration details specific to this driver. For this driver it is not required to specify modes in the Screen section of the configuration file. The wsfb driver picks up the currently used video mode from the framebuffer driver and uses it. Video modes specifications in the confi- guration file are ignored. The following driver options are supported in the Device section: Option "device" "string" The wsdisplay framebuffer device to use. Default: /dev/ttyC0. Option "ShadowFB" "boolean" Enable or disable use of the shadow framebuffer layer. See shadowfb(4) for further information. Default: on for depths were it is supported, off otherwise. ShadowFB is currently not supported on monochrome displays. XFree86 Version 4.5.0 1 WSFB(4) UNIX Programmer's Manual WSFB(4)
