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
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
