7.Nd wscons interface to amiga custom chips drivers
8.Sh SYNOPSIS
9.Cd amidisplaycc0 at mainbus0
10.Cd wsdisplay0 at amidisplaycc0
11.Sh DESCRIPTION
12This device acts as an adapter between the
13.Xr wscons 4
14framework and the Amiga custom chip driver functions.
15It exports the internal
16.Xr wsdisplay 4
17interface and contains the necessary rendering functions to
18operate a text terminal with virtual screens. It uses the
19Amiga abstract graphic driver (grfabs) functions for the low-level
20display management.
21.Pp
22Currently it does not support running X.
23It can however coexist well enough with grf0 to make possible running
24X the old way, but be warned, you cannot switch screens while
25in X and when quitting it, it seems to hang. Switching a screen
26then will bring up the text console. As always, we apologise for
27the inconvenience.
28.Pp
29What it does support is hilite (bold), underline, reverse and
30foreground/background colors.
31.Ss Virtual terminals and screen types
32The number of virtual screens is limited only by
33the available chip memory.
34.Pp
35Each virtual screen can have a different screen type.
36A screen type defines the following things: height and width
37in pixels, number of colors, and font size.
38The supported screen types are listed below.
39.Bl -bullet -offset indent -compact

4180x64 - display size 640x512 with 8 colors, font size 8x8

56.It
57default - same as either 80x64 or 80x50, depending on the presence
58of GRF_NTSC and GRF_PAL in the kernel configuration.
59.El
60.Pp
61The grfabs code determines the actual screen mode that is used.
62The config options GRF_NTSC, GRF_PAL, GRF_AGA, etc. determine
63what kind of chipsets/modes are available.
64.Ss Fonts
65Fonts of width 8 and any height are supported.
66Fonts can be compiled into the kernel by specifying "options FONT_[fontname]"
67in the configuration file, or loaded with the
68.Xr wsfontload 8
69utility runtime.
