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.
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
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.
- 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.
