Here are the results of my reorganization work on the zs driver.
|
|
Everything compiles and appears to work.
|
|
|
|
Enjoy!

----------------------------------------------------------------
|
|
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.

|
|
zsc1 at obio? addr ?
|
|
kbd0 at zsc0 channel 0
|
|
ms0 at zsc0 channel 1
|
|
