ef9805a3c8 Moved rtcin() to clock.c.
Always delay using one inb(0x84) after each i/o in rtcin() - don't
do this conditional on the bogus option DUMMY_NOPS not being defined.
If you want an optionally slightly faster rtcin() again, then inline
it and use a better named option or sysctl variable.  It only needs
to be fast in rtcintr().

cdf642d171 Whoops, back out the last commit, which was accidentally committed at

The commit that occurred was an incomplete patch for APM on my laptop

3addba4f55 No longer use the cyclecounter to attempt to correct for late or missed
clock interrupts.

Keep a 1-in-16 smoothed average of the length of each tick.  If the
CPU speed is correctly diagnosed, this should give experienced users
enough information to figure out a more suitable value for `tick'.

c8f2fe8db8 First attempt at creating devfs entries for sliced devices. Doesn't
quite work yet, so the heart of it is disabled.

Added bdev and cdev args to dsopen().

drivers:
Fixed device names, links, minor numbers and modes.

wd.c:
Started actually supporting devfs.

diskslice.h:
Added devfs tokens to structs (currently 576 of them per disk! :-().

subr_diskslice.c:
Create devfs entries in dsopen() and (unsuccessfully) attempt to make
them go away at the right times.  DEVFS is #undefed at the start so
that this shouldn't cause problems.

dd87702a51 Allocate DMA bounce buffers only when requested by drivers. Only the
fd and wt drivers need bounce buffers, so this normally saves 32K-1K
of kernel memory.

Keep track of which DMA channels are busy.  isa_dmadone() must now be
called when DMA has finished or been aborted.

Panic for unallocated and too-small (required) bounce buffers.

fd.c:
There will be new warnings about isa_dmadone() not being called after
DMA has been aborted.

sound/dmabuf.c:
isa_dmadone() needs more parameters than are available, so temporarily
use a new interface isa_dmadone_nobounce() to avoid having to worry
about panics for fake parameters.  Untested.

bfd6eab381 Fixed bugs introduced in rev. 1.127 (some broken 16650 support was
unintentionally committed):
- the fifo was completely disabled for low speeds.  Apart from being
  unnecessarily inefficient, this invalidated com->tx_fifo_size.
- `ftl' became a bogus name.
- the 16650 probe breaks the COM_NOFIFO() case and has other bugs
  (disabled, not fixed).

Fixed bogus change of the fifo settings for the non-speed of 0.  This
bug made the above fifo bug occur even at non-low speeds.

Fixed the modes of the cua devices.  It isn't possible to set the uid
and gid correctly since the kernel can't know who uucp.dialer is.

Register the devswitch at device attach time.  SYSINIT() is not
the right way to initialize devswitches (if anything :->).
Eventually, the devswitch should be deregistered at device detach
and/or unload time and reregistered at device attach time ...  Then
some com->gone tests could be removed.

Cleaned up some other recent changes.

d1022821ae Removed my devsw access functions [un]register_cdev() and
getmajorbyname() which were a better (sigh) temporary interface to
the going-away devswitches.

Note that SYSINIT()s to initialize the devswitches would be fatal
in syscons.c and pcvt_drv.c (and are bogus elsewhere) because they
get called independently of whether the device is attached; thus
devices that share a major clobber each other's devswitch entries
until the last one wins.

conf.c:
Removed stale #includes and comments.

81ab2caf0a Replaced nxreset by noreset (if the reset function gets called, then the
device must be configured.  It's hard to tell whether a reset function
should be noreset or nullreset since reset functions are never called.
Most drivers use nullreset but noreset has the advantage of complaining
if somehow gets called).

f332b8a1d5 Replaced nxdump by nodump (if the dump function gets called, then the

Removed duplicated comments and declarations of nonexistent switch
functions.

87f6c6625d Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..
complaints to the usual places.. :)
