da78ae6c96 Mass update of isa drivers using compatability shims to use
COMPAT_ISA_DRIVER() so that we can get rid of the evil isa_compat.h table.

38391cb38a Clean up some more loose ends..
isa_device->id_ri_flags and RI_FAST were not implemented and did nothing.
The two drivers that were mistakenly thinking this was working were
cy.c and loran.c - these should be converted to newbus.
GC (garbage collect) isa_device->id_alive
GC userconfig.c references to isa_device->id_scsiid (!).

a2c68c62db This patch clears the way for removing a number of tty related
fields in struct cdevsw:

        d_stop          moved to struct tty.
        d_reset         already unused.
        d_devtotty      linkage now provided by dev_t->si_tty.

These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.

The changes in this patch consist of:

        initialize dev->si_tty in *_open()
        initialize tty->t_stop
        remove devtotty functions
        rename ttpoll to ttypoll
        a few adjustments to these changes in the generic code
        a bump of __FreeBSD_version
        add a couple of FreeBSD tags

663cbe4fc2 Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

6a5dc97620 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

7e4a9dced9 This commit should be a extensive NO-OP:
Reformat and initialize correctly all "struct cdevsw".

        Initialize the d_maj and d_bmaj fields.

        The d_reset field was not removed, although it is never used.

I used a program to do most of this, so all the files now use the
same consistent format.  Please keep it that way.

41b420910c Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it.  Driver writers can do
this if it's not defined.  (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

3:
  s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/

The remaining suser_xxx() calls will be scrutinized and dealt with
later.

There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.

More changes to the suser() API will come along with the "jail" code.

efd89902e6 Use a fast interrupt handler for the PCI version of the cy driver
if option CY_PCI_FASTINTR is configured and mapping the irq to a
fastintr is possible.  Unfortunately, this has to be optional because
pci_map_int_right() doesn't handle the INTR_EXCL flag right --
INTR_EXCL is honoured even if the interrupt needs to be non-exclusive
for other devices to work.

66eea65587 Flush the fifos at the correct place in cyopen(). Various things
in cyopen() were done in a different order than in sioopen(), partly
to (ab)use a side effect of comparam() and partly because I didn't
understand what the reset was doing (it flushes the fifos).  This
turned out to be more than a cosmetic problem.  Flushing the fifos
quite late is good for discarding input that arrived while the line
state was being initialized, and in the cy driver it also seems to
reduce a problem with input that arrived long ago during the previous
close (the UART loses sync too easily and for too long).

3bb6da1b8b Wait for channel commands to complete after issuing the commands.
The optimisation of only waiting before issuing new commands is
obviously invalid in general and it caused many errors in NIST-PCTS.
I think the errors were mostly for characters sent with the wrong
parity, etc., after a half complete tcsetattr().

Use microtime() instead of a magic loop count to limit the wait.
The wait is a busy-wait :-( and normally takes about 500 usec.

b3eb962304 Flush the tx fifo in cystop(). Now ttyflush() (and thus tcflush(3))
almost works properly.  Unfortunately, there is no way to flush
the rx fifo without resetting the channel, which also flushes the
tx fifo.  We avoid resetting even when both fifos need to be flushed,
since resetting seems to cause the rx to lose sync if it is done
while data is arriving.

54f96be976 Implemented sending of BREAKs. This is quite complicated because the
hardware is interrupt-driven to a fault and sending a BREAK requires
mode switching.  Always running in the BREAK-capable mode as in PR 8318
would double the overhead for sending \0's.

9eb9485178 Fixed sloppy clearing of TS_BUSY. Don't clear it until the transmitter
is completely empty.  There is an interrupt for output completion.  It
is painful to use, but polling method used in the corresponding fix in
sio.c (rev.1.152) can't be used because there is no status bit for
transmitter-empty.  Now ttywait() works right.

461b5f77f6 Untangled the Cyclades offsets a little. CY16_RESET and CY_CLEAR_INTR
were half of their physical offsets for ISA and 1/4 of their physical
offsets for PCI, while all other Cyclades offsets were physical/1 for
ISA and physical/2 for PCI.  Logically wrong macros were used to scale
CY16_RESET and CY_CLEAR_INTR to the correct physical offsets.

96fbde25a2 Reduce i/o overheads by not preserving the channel access register in
interrupt handlers.  Instead, load and use it atomically as necessary.
This reduces mode switching overhead for "polled" mode interrupt handling
from 5 i/o's to 3 (per service type, per port) so that polled mode is only
slightly more inefficient than "interrupt" mode.

1524621152 Enabled dynamically sized tty input buffers (with enough buffering
for 1 second's worth of input) and larger tty output buffers.  The
interrupt-level buffers are still too small for speeds above 115200
bps (only a little too small for 230400 bps if RTS flow control is
enabled).

Don't call ttsetwater() explicitly in open().  It is now called for
the TTYDISC l_open() and should be static.

Don't attempt to register the cdevsw more than once.
