- 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.

respective NetBSD driver for use with the genclock interface.
It's first use will be on sparc64 but it was also tested on alpha with
a preliminary patch to switch alpha to use the genclock code together
with this driver instead of the respective code in alpha/alpha/clock.c
and the rather MD mcclock(4). Using it on i386 and amd64 won't be that
hard but some changes/extensions to improve the genclock code in general
should be done first, e.g. add locking and make it easier to access the
NVRAM usually coupled with RTCs.
- The claim in the commit log of rev. 1.11 of dev/uart/uart_cpu_sparc64.c
etc. that UARTs are the only relevant ISA devices on sparc64 turned out
to be false. While there are sparc64 models where UARTs are the only
devices on the ISA bus there are in fact also low-cost models where all
devices traditionally found on the EBus are hooked up to the ISA bus.
There are also models that use a mix between EBus and ISA devices with
things like an AT keyboard controller and other rather interesting
devices that we might want to support in the futute hook up to the ISA
bus.
In order to not need to add sparc64 specific device_identify methods to
all of the respective ISA drivers and also not add OFW specific code to
the common ISA code make the sparc64 ISA bus code fake up PnP devices so
most ISA drivers probe their devices without further changes.
Unfortunately Sun doesn't adhere to the ISA bindings defined in IEEE
1275-1994 for the properties of most of the ISA devices which would
allow to obtain the vendor and logical IDs from their properties. So we
we just use a simple table which maps the name properties to PnP IDs.
This could be done in a more sophisticated way but I courrently don't
see the need for this. [1]
- Add the children with fully mapped and specified resources (in the OFW
sense) similar to what is done in the EBus code for the IRQ resources
of the children as adjusting the resources and the resource list entries
respectively in isa_alloc_resource() as done perviously causes trouble
with drivers which use rman_get_start(), pass-through or allocate and
release resources multiple times, etc.
Adjusting the resources might be better off in a bus_activate_resource
method but the common ISA code currently doesn't allow for an
isa_activate_resource(). [2]
With this change:
- ppbus(4) and lpt(4) attach and work (modulo ECP mode, which requires
real ISADMA code but it currently only consists of stubs on sparc64).
- atkbdc(4) and atkbdc(4) attach, no further testing done.
- fdc(4) itself attaches but causes a hang while attaching fd0 also
when is DMA disabled, further work in fdc(4) is required here as e.g.
fd0 uses the address of fd1 on sparc64 (not sure if sparc64 supports
more than one floppy drive at all).
All of these drivers previously caused panics in the sparc64 ISA code.
- Minor changes, e.g. use __FBSDID, remove a dupe word in a comment and
declare one global variable which isn't used outside of isa.c static.
o dev/uart/uart_cpu_sparc64.c and modules/uart/Makefile:
- Remove the code for registering the UARTs on the ISA bus from the
sparc64 uart_cpu_identify() again and rely on probing them via PnP.

If passed NULL, the old behaviour using bus_space_{read,write}_1() is

This is necessary for mvmeppc boards where the mk48txx NVRAM/RTC is
