|
|
.Sh NAME
|
|
.Nm amidisplaycc
|
|
.Nd wscons interface to amiga custom chips drivers
|
|
.Sh SYNOPSIS
|
|
.Cd amidisplaycc0 at mainbus0
|
|
.Cd wsdisplay0 at amidisplaycc0
|
|
.Sh DESCRIPTION
|
|
This device acts as an adapter between the
|
|
.Xr wscons 4
|
|
framework and the Amiga custom chip driver functions.
|
|
It exports the internal
|
|
.Xr 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.
|
|
.Pp
|
|
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. As always, we apologise for
|
|
the inconvenience.
|
|
.Pp
|
|
What it does support is hilite (bold), underline, reverse and
|
|
foreground/background colors.
|
|
.Ss Virtual terminals and screen types
|
|
The number of virtual screens is limited only by
|
|
the available chip memory.
|
|
.Pp
|
|
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.
|
|
.Bl -bullet -offset indent -compact
|
|

|
|
80x64 - display size 640x512 with 8 colors, font size 8x8

|
|
80x51 - display size 640x510 with 8 colors, font size 8x10

|
|
.It
|
|
80x24 - display size 640x192 with 8 colors, font size 8x8
|
|
.It
|
|
default - same as either 80x64 or 80x50, depending on the presence
|
|
of GRF_NTSC and GRF_PAL in the kernel configuration.
|
|
.El
|
|
.Pp
|
|
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.
|
|
.Ss 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
|
|
.Xr wsfontload 8
|
|
utility runtime.
