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. As always, we apologise for the inconvenience.
What it does support is hilite (bold), underline, reverse and foreground/background colors.
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.
