device cloned, and assign all further devices to depend on it. This
allows us to call dev_depends() on it at module unload time to get rid
of /dev/snp* (in the devfs case, anyway). For this to work, we must
not destroy the device at close time. [Idea stolen from if_tun.]
The above has the following sideaffects: (a) The snp device used by
watch(8) will remain after watch(8) exits. This is probably how it
should have been all along, and how it was before devfs came along.
(b) Module unload doesn't panic if there are any /dev/snp* devices
which haven't been used (and thus previously destroyed). Thus, we can
reenable the unload functionality disabled in rev. 1.65.

off chip that was on one prototype board. However, this appears to be
a design that many chipsets are compatible with its PPEC register set
(eg the Omega 82c094). Through the kindness of the Red Hat developer
David Woodhouse, I now have this datasheet.
I may take the advise of one of the bsd-nomads (whose name
unfortunately escapes me at the moment) and split out all these 16-bit
I/O mapped PCI devices into a separate driver...
that it has one BAR that's mapped to 0x3e0 and is I/O only. It does
not conform to the Yenta spec, like other PCI PCMICA bridges do (eg
the TI 1031, which is mostly a 1131 w/o 32bit card support). It
appears that this chip may also need to not route PCI interrupts
as well.
This chip is used in the NEC Versa 2430CD (and it appears that
sometimes it works, while other times it doesn't) and others in the
2400 series. While the NEC website claims Cardbus support, I can't figure
out how that is possible.

This emulates APM device node interface APIs (mainly ioctl) and
provides APM services for the applications. The goal is to support
most of APM applications without any changes.
Implemented ioctls in this commit are:
- APMIO_SUSPEND (mapped ACPI S3 as default but changable by sysctl)
- APMIO_STANDBY (mapped ACPI S1 as default but changable by sysctl)
- APMIO_GETINFO and APMIO_GETINFO_OLD
- APMIO_GETPWSTATUS
With above, many APM applications which get batteries, ac-line

- Count the number of this error.
- When the error is detected for the first time, the psm driver will
throw few data bytes (up to entire packet size) and see if it can
get back to sync.
- If the error still persists, the psm driver disable/enable the mouse
and see if it works.
- If the error still persists and the count goes up to 20,
the psm driver reset and reinitialize the mouse. The counter
is reset to zero.
- It also discards an incomplete data packet when the interval
between two consequtive bytes are longer than pre-defined timeout
(2 seconds). The last byte which arrived late will be regarded as
the first byte of a new packet. This is louie's idea.
You may see the following error logs during the above operations:
"psmintr: delay too long; resetting byte count"
"psmintr: out of sync (%04x != %04x)"
"psmintr: discard a byte (%d)"
"psmintr: re-enable the mouse"
