This device acts as an adapter between the
wscons(4) framework and the
Amiga custom chip driver functions. It exports the internal
wsdisplay(4) interface and
contains the necessary rendering functions to operate a text terminal with
virtual screens. It uses the Amiga abstract graphic driver (grfabs) functions
for the low-level display management.
The X11 server works in monochrome mode using the
wsfb(4) driver.
It supports foreground and background color, and the hilite
(bold), underline, and reverse text attributes.
The number of virtual screens is limited only by the available chip memory.
Each virtual screen can have a different screen type. A screen
type defines the following things: height and width in pixels, number of
colors, and font size. The supported screen types are listed below.
- 80x64 - display size 640x512 with 8 colors, font size 8x8
- 80x51 - display size 640x510 with 8 colors, font size 8x10
- 80x50 - display size 640x400 with 8 colors, font size 8x8
- 80x40 - display size 640x400 with 8 colors, font size 8x10
- 80x32 - display size 640x512 with 8 colors, font size 8x16
- 80x31 - display size 640x248 with 8 colors, font size 8x8
- 80x25 - display size 640x400 with 8 colors, font size 8x16
- 80x24 - display size 640x192 with 8 colors, font size 8x8
- default - same as either 80x64 or 80x50, depending on the presence of
GRF_NTSC and GRF_PAL in the kernel configuration.
The grfabs code determines the actual screen mode that is used.
The config options GRF_NTSC, GRF_PAL, GRF_AGA, etc. determine what kind of
chipsets/modes are available.
Fonts of width 8 and any height are supported. Fonts can be compiled into the
kernel by specifying "options FONT_[fontname]" in the configuration
file, or loaded with the
wsfontload(8) utility
runtime.
