the ISA and CBUS (called isa on pc98) attachments. Eliminate all PC98
ifdefs in the process (the driver in pc98/pc98/mse.c was a copy of the one
in i386/isa/mse.c with PC98 ifdefs). Create a module for this driver.
I've tested this my PC-9821RaS40 with moused. I've not tested this on i386
because I have no InPort cards, or similar such things. NEC standardized
on bus mice very early, long before ps/2 mice ports apeared, so all PC-98
machines supported by FreeBSD/pc98 have bus mice, I believe.

without Open Firmware:
- The PCI data structure of some HME PROMs contains a non-zero interface
revision in the class code. Thus remove the checks for matching class
code and PCI data structure length and revsion. These were pretty much
useless anyway as we only really need the pointer to the VPD which is
located before the structure length and revision fields.
- On Sun QFE (Quad FastEthernet) cards read the Nth MAC-address for the
Nth HME controller instead of always the first one for all four HMEs. [1]

the PCI bus. We presently have no drivers for these devices, so they
are powered down. This is undesirable behavior since it breaks the
system when the base peripherals go away suddenly in the middle of
boot.
# if we ever get generic drivers for memory and/or base peripherals, then
# we can remove the tests here.
These devices should be probed first because they are at fixed
locations and cannot be turned off. ISA PNP devices, on the other
hand, can be turned off and often can be flexible in the resources
they use. Probe them last, as always.

in the _PRS or _CRS of link devices. If faced with multiple DPFs in a
_PRS, we just use the first one. We assume that if _CRS has DPF tags they
only contain a single set since multiple DPFs wouldn't make any sense. In
practice, the only DPFs I've seen so far for link devices are that the one
IRQ resource is surrounded by a DPF tag pair for no apparent reason, and
this should handle that case fine now.
- Only allocate link structures for IRQ resources for link devices rather
than allocating a link structure for every resource.

- Hardcode channel 1 for the keyboard on Z8530, the information present

avoid the hang that revision works around) and consequently syscons(4)

- Use a new-bus device driver for the ACPI PCI link devices. The devices
are called pci_linkX. The driver includes suspend/resume support so that
the ACPI bridge drivers no longer have to poke the links to get them
to handle suspend/resume. Also, the code to handle which IRQs a link is
routed to and choosing an IRQ when a link is not already routed is all
contained in the link driver. The PCI bridge drivers now ask the link
driver which IRQ to use once they determine that a _PRT entry does not
use a hardwired interrupt number.
- The new link driver includes support for multiple IRQ resources per
link device as well as preserving any non-IRQ resources when adjusting
the IRQ that a link is routed to.
- The entire approach to routing when using a link device is now
link-centric rather than pci bus/device/pin specific. Thus, when
using a tunable to override the default IRQ settings, one now uses
a single tunable to route an entire link rather than routing a single
device that uses the link (which has great foot-shooting potential if
the user tries to route the same link to two different IRQs using two
different pci bus/device/pin hints). For example, to adjust the IRQ
that \_SB_.LNKA uses, one would set 'hw.pci.link.LNKA.irq=10' from the
loader.
- As a side effect of having the link driver, unused link devices will now
be disabled when they are probed.
- The algorithm for choosing an IRQ for a link that doesn't already have an
IRQ assigned is now much closer to the one used in $PIR routing. When a
link is routed via an ISA IRQ, only known-good IRQs that the BIOS has
already used are used for routing instead of using probabilities to
guess at which IRQs are probably not used by an ISA device. One change
from $PIR is that the SCI is always considered a viable ISA IRQ, so that
if the BIOS does not setup any IRQs the kernel will degenerate to routing
all interrupts over the SCI. For non ISA IRQs, interrupts are picked
from the possible pool using a simplistic weighting algorithm.
