5575abefeb Fight with hanging modems continued:
return EIO after t_timeout expired instead infinite looping in "siotx"
in comparam, consuming CPU time.

33dc7e1b84 Reduce timeout frequency from `hz' to 0 if no ports are open or to 1 if
no ports are active, provided there are no polled ports and no
`LOSESOUTINTS' ports.  Do a little more in the interrupt handler instead.
This is a little less efficient if there are are many active ports but
a little more efficient otherwise.  Polled ports are ones with no irq
specified (as before).  `LOSESOUTINTS' ports are ones with 0x08 set in
their config flags.  Unless this flag is set, it will now take up to one
second to recover from lost output interrupts, if any.  Some 8250s and
16450s lose output interrupts.

Improve output buffering: copy the clist buffer to 2 linear buffers if
necessary and possible instead of to 1.  Handle an arbitrary queue of
buffers in the interrupt handler.  Check for waking up sleepers after
copying characters out of the clist buffer instead of before.

Delay translation of TIOCM_DTR to MCR_DTR etc. so that the top level
routines are more machine independent.

Fix bogus device register in unused code.

b2b795f07c Fix -Wformat warnings from LINT kernel. 1995-05-11 19:26:53 +00:00
Bruce Evans
d81fba0cda Add variable `idelayed' and macros setdelayed() and schedsofttty()
to access it.  setdelayed() actually ORs the bits in `idelayed' into
`ipending' and clears `idelayed'.

Call setdelayed() every (normal) clock tick to convert delayed
interrupts into pending ones.

Drivers can set bits in `idelayed' at any time to schedule an interrupt
at the next clock tick.  This is more efficient than calling timeout().
Currently only software interrupts can be scheduled.

85827d9c13 Restructured the floppy tape probe.
The ``flags 1'' in the fdc line is now only needed for owners of an
Insight tape (perhaps there aren't any?  Mine is disfunctional).  All
other probes are safe wrt. to the motor-control line of floppy disk
drives.  Document the flag in LINT finally.

04a6a5a9ac ttsetcompat is a '#ifdef COMPAT_43' feature.
Dropping into the debugger when a break comes down the serial line is a
>MISFEATURE (1st class)< and has been put under it's own #ifdef.  This
should be a magic sequence of chars instead.

6c0081e92b Add a class field to devconf and mst drivers.
For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago).  For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device.  The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out.  A few bytes saved by using
%b to format the features list rather than lots of ifs.

2cad35d11b Several fixes to help "raw" tty mode work correctly with
BREAK/parity/framing errors.
Term "correctly" assumes POSIX spec. and 4.4 ttyinput() behaviour.
1) Discard BREAK/parity at interrupt level when apropriate IGN*
is set in iflag. It helps "raw" mode works even IGN* is set.
2) Zero parity (if INPCK) and framing directly in buffer
before passing it to b_to_q() in "raw" mode.
Efficency:
interrupt level: if no error occurse, only two "test" commands added
"raw" mode: buf scan incc times for parity/framing added
