Well, these Super IO chips not only affect Parport. So this would be a new
directory in the ../linux/drivers -tree, like drivers/pnp.
I am trying to implement something like this:
/proc/superio/superio: Lists available Superio Chips
/proc/superio/0: Entry for first chip
/proc/superio/1: Entry for second chip
The content of a chip-entry would be lines with Keywords and values.
A cat on that /proc/superio/0 file would give something like
in random order ,as different chips have different features. Creating single
proc entries for every feature would seem to me like a daunting task...
Writing on some items would be allowed in some situations, like
"echo "ppaddr 278" >/proc/superio/0
would change the parallel port address, if the old adress isn't actual used.
Exporting the Super IO Chip registers and decoding these in a user programm
would be another possibility. However I feel bad about letting the user
program write random registers...
