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.

thorpej 13ad8f5ba7 Pack the minor numbers like the Cyclades-Z driver does, and
make the dialout bit compatible with the other serial drivers
(and with what MAKEDEV generates for dtyCYxxx).

sommerfeld dcf6e7b09e When receiving an rx interrupt on a closed or unconfigured port, read
the data out of the board anyway so it won't re-interrupt anyway.

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

mjacob 019508faee Well, I don't have a Cyclades board, but I needed the alpha kernels
to compile. I made the changes that seemed to make sense tracking the
shift from TS_WOPEN  to tp->t_wopen- but they may be wrong. I wasn't
subscribed to tech-kern so I missed the discussion, and C. Hannum
was not particularly enlightening. Sorry if this isn't quite right.

cgd 57f46a9e4a fix several bugs pointed out by Jarkko Torppa <torppa@cute.fi> in PR 3753:
(1) fix a printf format (%x to print int, not %lx).
(2) fix probe of 4th chip/16th channel (used to tell whether or not the
    board is a 16- or 32-port board) by removing an incorrect offset so
    that the code matched its comments. (!!!)
(3) fix storage of chip number in per-channel structure so that it actually
    stores the chip number, rather than the chip offset.  This allows the
    driver to work with more than the first four channels (i.e. with chips
    other than chip number 0, which happens to have an offset of zero). (!!!)

cgd 04e7505aaa clean up an autoconfiguration printf. Much more should be done 1997-04-13 20:00:29 +00:00
thorpej 16c4c5af26 New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.
