things tend to work better if you write the settings to the correct
register.. (*blush*). This subtle bug has been haunting me for ages, and
will solve a few problems that have been reported to me.
Also, take a shot at fixing the serial BREAK processing, what was there
before never really worked. (There is a PR on this I think)
Real support for a Textmode mousecursor, works by reprogramming the
charset. Together with this support for cut&paste in text mode.
To use it a userland daemon is needed (moused), which provides
the interface to the various mice protokols.

too much about the icu (most only use it to convert `n' to `IRQn'). isa.h
is only used by ioconf.c and by a few drivers that know too much about
isa addresses (a few have to, because config is deficient).

is a problem area for the PC98 merge - all PC98 ifdefs in <machine/*.h> are
kludges to work around incorrect layering.
Original version by John Hay.
Simplified timestamp code by reading the time exactly when necessary.
This may slow down the interrupt handler with extra calls to microtime(),
but only in bad configurations - the input fifo should normally be
disabled if timestamps on input are being used, since otherwise the
timestamp won't be precisely associated with any particular input event.
The interrupt handler remains slowed down by one test and branch for
each input (and now DCD change) event - avoiding this is not practical
yet.
The simplifications also fixed:
- timestamps for input sometimes being clobbered by output and modem
status interrupts.
- valid timestamps not being available unless the port is configured with
vector siointrts. siointrts no longer exists.
- compiler warnings about siointr* in some configurations.
Simplified timestamp and probe code by depending on recent changes in
microtime() and DELAY() to preserve the interrupt enable flag.
enable flag instead of enable_intr() to restore it to its usual state.
getit() is only called from DELAY() so there is no point in optimising
its speed (this wasn't so clear when it was extern), and using
enable_intr() made it inconvenient to call DELAY() from probes that need
to run with interrupts disabled.
instead of sti to it restore to its usual state. pushfl/popfl is
actually faster in protected mode on Pentiums (4+3 cycles instead of 9),
and using sti made it extremely inconvenient to call microtime() from
fast interrupt handlers. pushfl/popfl is a couple of cycles slower than
sti on 486's and a couple more cycles slower on 386's, but the relative
cost of using it is not large since microtime() has to use slow i/o
instructions on the old cpus.
1) Make it much less likely to miss a wakeup in vm_page_free_wakeup
2) Create a new entry point into pmap: pmap_ts_referenced, eliminates
the need to scan the pv lists twice in many cases. Perhaps there
is alot more to do here to work on minimizing pv list manipulation
3) Minor improvements to vm_pageout including the use of pmap_ts_ref.
4) Major changes and code improvement to pmap. This code has had
several serious bugs in page table page manipulation. In order
to simplify the problem, and hopefully solve it for once and all,
page table pages are no longer "managed" with the pv list stuff.
Page table pages are only (mapped and held/wired) or
(free and unused) now. Page table pages are never inactive,
active or cached. These changes have probably fixed the
hold count problems, but if they haven't, then the code is
simpler anyway for future bugfixing.
5) The pmap code has been sorely in need of re-organization, and I
have taken a first (of probably many) steps. Please tell me
if you have any ideas.

this is in place I would like to fixup the PCCARD hooks and remove the

[ This works on both my 3C589B and 3C589C ]
My 3C509B-COMBO works fine with the following patch. Switching between
UTP and BNC is quite easy. (Just type 'ifconfig ep0 link1 -link2' or 'ifconifg
ep0 link2 -link1'.)

It is called from copyin and copyout.
The new routine is conditioned on I586_CPU and I586_FAST_BCOPY, so you
need
options "I586_FAST_BCOPY"
(quotes essenstial) in your kernel config file.
Also, if you have other kernel types configured in your kernel, an
additional check to make sure it is running on a Pentium is inserted.
(It is not clear why it doesn't help on P6s, it may be just that the
Orion chipset doesn't prefetch as efficiently as Tritons and friends.)
Bruce can now hack this away. :)
Smart Capture Card is a kind of video capture card, PCMCIA type II,
and made by IBM Japan co.. Unfortunately, it is sold in Japan now.
The device driver is working on the latest pccard-test package by
Tatsumi HOSOKAWA and bsd-nomads. Some applications are also working.
For example, xscc is a video moniter client on X-window, vic-2.7b2 is
a video conference tool.
We have a contract with IBM Japan. From the contract, we cannot release
the source code exept the permit of IBM Japan. But I think they will
permit us in few weeks.
