atatat 31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

scw 2963ff5c58 Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point
in each tty driver to indirect through it.

This allows tty line-disciplines to handle poll(2) system calls.

sommerfeld 851de295eb Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

wrstuden eb21ed4746 Adapt to going back to decemal device numbering. 2000-06-09 18:00:45 +00:00
wrstuden 8d04cd3f90 Rather than assinging 64 tty's per pci card, assign tty's as found.
Cyclades says driver should work with up to 128 tty's per pci card
even though they only support 64 now. Also matches FreeBSD behavior.

Print located tty's using new tty naming scheme - ttyCZ?? where ?? are
two hex letters.

Make firmware load on macppc - one le32toh() was missing.

thorpej 4f92d2cd54 Update from Bill Studenmund <wrstuden@zembu.com>:
- Note that the FreeBSD driver distributed by Cyclades served as
  documentation on how the board works.
- Use the wait-until-pending-I/O-completes-before-loading-parameters
  command in czttyparam().
- Pass BREAKs up to the tty later properly.
- Garbage-collect some debugging code.

thorpej 5c9920bbb6 Update from Bill Studenmund <wrstuden@zembu.com>:
Correctly send and receive BREAKs -- still needs to do something
intelligent with them.  Some additional debugging goo.
