Here are the results of my reorganization work on the zs driver.
Everything compiles and appears to work.
Enjoy!
Gordon Ross
----------------------------------------------------------------
This design has a "zs controller" named "zsc" with three
flavors of child drivers that can be attached above it.
The three child drivers are:
zstty: normal RS-232 line
kbd: sun keyboard
ms: sun mouse
Note that the machine-dependent parts are:
arch/sun3/include/z8530var.h
arch/sun3/dev/zs.c
(replicate those for new systems)
The Sun hardware dependent parts (Sun3 and SPARC) are:
kd* sun keyboard/display console stuff
event* sun "firm event" stuff
----------------------------------------------------------------
Here is how the autoconfig looks on a sun3:
zsc0 at obio0 addr 0x0 level 6 softpri 3
kbd0 at zsc0 channel 0
ms0 at zsc0 channel 1
zsc1 at obio0 addr 0x20000 level 6 softpri 3
zstty0 at zsc1 channel 0 (console)
zstty1 at zsc1 channel 1
----------------------------------------------------------------
Config lines:
In any config file (i.e. GENERIC, NEW_ZS, ...)
Note {kbd,ms} are sun-specific.
#
# New console (zs) stuff
#
zsc0 at obio? addr ?
zsc1 at obio? addr ?
kbd0 at zsc0 channel 0
ms0 at zsc0 channel 1
zstty* at zsc? channel ?
----------------------------------------------------------------
In conf/files.sun3
#
# Console (zs) related stuff
#
device zsc at obio {channel = -1}
file arch/sun3/dev/zs.c zsc needs-flag
file dev/ic/z8530sc.c zsc
device zstty at zsc: tty
file dev/ic/z8530tty.c zstty needs-flag
define zsevent
file dev/sun/event.c zsevent
device kbd at zsc: zsevent
file dev/sun/kbd.c kbd needs-flag
file dev/sun/kbd_tables.c kbd
file arch/sun3/dev/kd.c kbd
device ms at zsc: zsevent
file dev/sun/ms.c ms needs-flag
