wsfb - video driver for wsdisplay framebuffer device
wsfb is an Xorg driver for OpenBSD and NetBSD wsdisplay framebuffer
devices. This is a non-accelerated driver. The following 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 configurations are supported.
The wsfb driver supports all hardware where a wsdisplay framebuffer
driver is available on OpenBSD and NetBSD. On OpenBSD, currently this
includes OpenBSD/macppc, OpenBSD/sgi, OpenBSD/sparc, OpenBSD/sparc64
and OpenBSD/alpha on TGA graphics cards. It also supports NetBSD/i386
using wsdisplay on vesafb(4).
Please refer to xorg.conf(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 sec-
tion 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 configuration file are ignored.
The following driver options are supported in the Device section:
Option "device" "string"
The wsdisplay framebuffer device to use. Default for OpenBSD:
/dev/ttyC0. Default for NetBSD: /dev/ttyE0.
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.
Option "Rotate" "string"
Enable rotation of the display. The supported values are "CW"
(clockwise, 90 degrees), "UD" (upside down, 180 degrees) and
"CCW" (counter clockwise, 270 degrees). Implies use of the
shadow framebuffer layer. Default: off.
