a band-aid allowing to call this function savely multiple times, e.g.
during sckbdprobe() and sc_probe_unit(). Otherwise calling it a second
time results in a non-working keyboard. This needs a lot of more work
to actually do the right thing and work like expected.
- Let sunkbd_configure() return the number of the found keyboards, i.e.
1 in case probing succeeds, as it's expected. The return values of the
keyboard configure functions however currently aren't checked so this
doesn't make a difference at the moment.
- Use FBSDID.

it if necessary, i.e. set the respective IVAR to the right value for
allocating the IRQ resource, as some of them come up having it set
to 0 (in fact in all machines I'm currently aware of the FireWire

We can't call KeFlushQueuedDpcs() during bootstrap (cold == 1), since
the flush operation sleeps to wait for completion, and we can't sleep
here (clowns will eat us).
On an i386 SMP system, if we're loaded/probed/attached during bootstrap,
smp_rendezvous() won't run us anywhere except CPU 0 (since the other CPUs
aren't launched until later), which means we won't be able to set up
the GDTs anywhere except CPU 0. To deal with this case, ctxsw_utow()
now checks to see if the TID for the current processor has been properly
initialized and sets up the GTD for the current CPU if not.
Lastly, in if_ndis.c:ndis_shutdown(), do an ndis_stop() to insure we
really halt the NIC and stop interrupts from happening.
Note that loading a driver during bootstrap is, unfortunately, kind of
a hit or miss sort of proposition. In Windows, the expectation is that
by the time a given driver's MiniportInitialize() method is called,
the system is already in 'multiuser' state, i.e. it's up and running
enough to support all the stuff specified in the NDIS API, which includes
the underlying OS-supplied facilities it implicitly depends on, such as
having all CPUs running, having the DPC queues initialized, WorkItem
threads running, etc. But in UNIX, a lot of that stuff won't work during
bootstrap. This causes a problem since we need to call MiniportInitialize()
at least once during ndis_attach() in order to find out what kind of NIC
we have and learn its station address.
What this means is that some cards just plain won't work right if
you try to pre-load the driver along with the kernel: they'll only be
probed/attach correctly if the driver is kldloaded _after_ the system
has reached multiuser. I can't really think of a way around this that
would still preserve the ability to use an NDIS device for diskless
booting.
prevent anything from making calls to the NIC while it's being shut down.
This is yet another attempt to stop things like mdnsd from trying to
poke at the card while it's not properly initialized and panicking
the system.

one on AX1105 boards). This fixes attaching affected controllers.
Correcting the intpin value might be better off in the PCI code
via a quirk table but on the other hand gem(4) and hem(4) also
correct it themselves and at least for the USB controller part
the intpin register is truely hardwired to 0 and can't be changed.
This means that we would have to hook up the quirk information
in a lot of places in the PCI code (i.e. whenever the value of the
intpin register is read from or written to the pci_devinfo of the
respective device) in order to do it the right way.

- Add locking.
- Account for if the MC146818_NO_CENT_ADJUST flag is set we don't need
to check wheter year < POSIX_BASE_YEAR.
- Add some comments about mapping the day of week from the range the
generic clock code uses to the range the chip uses and which I meant
to add in the initial version.
- Minor clean-up, use __func__ instead of hardcoded function names in
error strings.
o in the rtc(4) front-end additionally:
- Don't leak resources in case mc146818_attach() fails.
- Account for ebus(4) defaulting to SYS_RES_MEMORY for the memory
resources since ebus.c rev. 1.22.
- Add support for storing the century in MK48TXX_WDAY_CB on MK48Txx with
extended registers when the MK48TXX_NO_CENT_ADJUST flag is set (and which
is termed somewhat confusing as it actually means don't manually adjust
the century in the driver).
- Add the MI part of interfacing the watchdog functionality of MK48Txx with
extended registers with watchdog(9). This is inspired by the SunOS/Solaris
drivers for the 'eeprom' devices also having watchdog support. I actually
expected this to work out of the box on Sun Exx00 machines with 'eeprom'
devices which have a 'watchdog-enable' property. On terminal count of the
the watchdog timer however only the MK48TXX_FLAGS_WDF bit rises but the
reset signal and the interrupt respectively (depending on whether the
MK48TXX_WDOG_WDS bit of the chip and the MK48TXX_WDOG_ENABLE_WDS flag
of the driver respectively is set) goes nowhere. Apparently passing the
reset signal on to the WDR line of the CPUs has to be enabled somewhere
else but we don't have documentation for the Exx00 specific controllers.
I decided to commit this nevertheless so it can be enabled in the eeprom(4)
front-end later in e.g. 6.0-STABLE without breaking the API. Besides the
Exx00 the watchdog part of the MK48Txx should also work on E250 and E450.
Possibly also without extra fiddling on these machines but I haven't
found someone willing to give it a try on such a machine so far.

front-end and the LSI64854 and NCR53C9x code in case one of these
functions fails. Add detach functions to these parts and make esp(4)
detachable.
- Revert rev. 1.7 of esp_sbus.c, since rev. 1.34 of sbus.c the clockfreq
IVAR defaults to the per-child values.
- Merge ncr53c9x.c rev. 1.111 from NetBSD (partial):
On reset, clear state flags and the msgout queue.
In NetBSD code to notify the upper layer (i.e. CAM in FreeBSD) on reset
was also added with this revision. This is believed to be not necessary
in FreeBSD and was not merged.
This makes ncr53c9x.c to be in sync with NetBSD up to rev. 1.114.
- Conditionalize the LSI64854 support on sbus(4) only instead of sbus(4)
and esp(4) as it's also required for the 'dma', 'espdma' and 'ledma'
busses/devices as well as the 'SUNW,bpp' device (printer port) which
all hang off of sbus(4).
- Add a driver for the 'dma', 'espdma' and 'ledma' (pseudo-)busses/
devices. These busses and devices actually represent the LSI64854 DMA
engines for the ESP SCSI and LANCE Ethernet controllers found on the
SBus of Ultra 1 and SBus add-on cards. With 'espdma' and 'ledma' the
'esp' and 'le' devices hang off of the respective DMA bus instead of
directly from the SBus. The 'dma' devices are either also used in this
manner or on some add-on cards also as a companion device to an 'esp'
device which also hangs off directly from the SBus. With the latter
variant it's a bit tricky to glue the DMA engine to the core logic of
the respective 'esp' device. With rev. 1.35 of sbus.c we are however
guaranteed that such a 'dma' device is probed before the respective
'esp' device which simplifies things a lot. [1]
- In the esp(4) SBus front-end read the part-unique ID code of Fast-SCSI
capable chips the right way. This fixes erroneously detecting some
chips as FAS366 when in fact they are not. Add explicit checks for the
FAS100A, FAS216 and FAS236 variants instead treating all of these as
ESP200. That way we can correctly set the respective Fast-SCSI config
bits instead of driving them out of specs. This includes adding the
FAS100A and FAS236 variants to the NCR53C9x core code. We probably
still subsume some chip variants as ESP200 while in fact they are
another variant which however shouldn't really matter as this will
only happen when these chips are driven at 25MHz or less which implies
not being able to run Fast-SCSI. [3]
- Add a workaround to the NCR53C9x interrupt handler which ignores the
stray interrupt generated by FAS100A when doing path inquiry during
boot and which otherwiese would trigger a panic.
- Add support for the 'esp' devices hanging off of a 'dma' or 'espdma'
busses or which are companions of 'dma' devices to esp(4). In case of
the variants that hang off of a DMA device this is a bit hackish as
esp(4) then directly uses the softc of the respective parent to talk
to the DMA engine. It might make sense to add an interface for this
in order to implement this in a cleaner way however it's not yet clear
how the requirements for the LANCE Ethernet controllers are and the
hack works for now. [2]
This effectively adds support for the onboard SCSI controller in
Ultra 1 as well as most of the ESP-based SBus add-on cards to esp(4).
With this the code for supporting the Performance Technologies SBS430
SBus SCSI add-on cards is also largely in place the remaining bits
were however omitted as it's unclear from the NetBSD how to couple
the DMA engine and the core logic together for these cards.

The Ralink RT2500 driver uses this API instead of NdisMIndicateReceivePacket().
Drivers use NdisMEthIndicateReceive() when they know they support
802.3 media and expect to hand their packets only protocols that want
to deal with that particular media type. With this API, the driver does
not manage its own NDIS_PACKET/NDIS_BUFFER structures. Instead, it
lets bound protocols have a peek at the data, and then they supply
an NDIS_PACKET/NDIS_BUFFER combo to the miniport driver, into which
it copies the packet data.
Drivers use NdisMIndicateReceivePacket() to allow their packets to
be read by any protocol, not just those bound to 802.3 media devices.
To make this work, we need an internal pool of NDIS_PACKETS for
receives. Currently, we check to see if the driver exports a
MiniportTransferData() method in its characteristics structure,
and only allocate the pool for drivers that have this method.
This should allow the RT2500 driver to work correctly, though I
still have to fix ndiscvt(8) to parse its .inf file properly.
Also, change kern_ndis.c:ndis_halt_nic() to reap timers before
acquiring NDIS_LOCK(), since the reaping process might entail sleeping
briefly (and we can't sleep with a lock held).
