NAME
amidisplaycc —
wscons interface to
amiga custom chips drivers
SYNOPSIS
amidisplaycc0 at mainbus0
wsdisplay0 at amidisplaycc0
DESCRIPTION
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.
Currently it does not support running X. It can however coexist well enough with
grf0 to make possible running X the old way, but be warned, you cannot switch
screens while in X and when quitting it, it seems to hang. Switching a screen
then will bring up the text console.
It supports foreground and background color, and the hilite (bold), underline,
and reverse text attributes.
Virtual terminals and
screen types
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
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.
