goal here is to get the P-5064 PCMCIA slots working, and serve as
the basis for P-6032 interrupt support.
PCMCIA interrupt auto-detection not working -- more work to be
done here.
- Compute the number of CPU pipeline cycles per second using the
mc146818.
- Use the COMPARE interrupt for the hardclock interrupt.
- Collapse all interrupt priorities into a single priority, and use
the CPU interrupt inputs to determine the interrupt source (local
device, PCI device, ISA device, etc.)
This allows us to have interrupt sharing.
- Set XS_TIMEOUT on a selection timeout condition.
- Do not bother to call AscStartChip() in AscResetChipAndScsiBus()--
just clear the chip status.
- Make sure address is word-aligned in AscWriteLramByte().
Tested on my adv (AdvanSys ABP-9xxUA) with CRW8424S and UMAX SuperVista S-12.
Earlier versions of the system would get stuck trying to recover from error
conditions when the CD-RW drive was in heavy use. I have not seen that
behavior with these small patches.
with the correct one referenced by a pointer in the podule structure. This is
in aid of eventually making the netslot and podulebus code a little more
separate from one another.

in nmi_sun4m(), if this is a soft NMI and DDB is configured, setup a trapframe
and pass it to nmi_soft(). in cpu_hatch(), spin until our cpu's flags no longer
have CPUFLG_STARTUP set. then, setup registers and jump to

Also, while here, fix CPU clock speed calculation for the Indy.

- Implement crude multicast support -- enable reception of all multicast
frames if we have any addresses on the multicast list. TODO: use the
64-bit hash table on the 80c03.
- Implement promiscuous mode.
IPv6 doesn't quite work yet -- DAD finds a duplicate for the

is not set, so I'm a little confused.

Also, query the "ConsoleOut" ARCS variable (i.e. "what the console

sync'ing the descriptor, leading to a race where the packet could complete
after the DMA check but before the sync of the descriptor, sending the code
into unknown territory and the DMA engine into space. Also, fix a bug with
spurious watchdog resets going off due to the if_timer not always being set
on transmit.
Finally, clean up use of hardcoded magic numbers, get them from hpcreg.h

The Milan configuration is split up in 2 parts:

Supports the traditionally formatted IDE disks on the Milan
- MILAN_PCIIDE
Supports the byte swapped formatted IDE disks on the Milan

NOSTREAM options to the flags of the generic ISA frontend.
There was probably to much byteswapping in my brain when I invented this.
fdexpand(). The former will return ENOSPC if there is not space
in the current filedesc table. The latter performs the expansion
of the filedesc table. This means that fdalloc() won't ever block,
and it gives callers an opportunity to clean up before the
potentially-blocking fdexpand() call.
Update all fdalloc() callers to deal with the need-to-fdexpand() case.
Rewrite unp_externalize() to use fdalloc() and fdexpand() in a
safe way, using an algorithm suggested by Bill Sommerfeld:
- Use a temporary array of integers to hold the new filedesc table
indexes. This allows us to repeat the loop if necessary.
- Loop through the array of file *'s, assigning them to filedesc table
slots. If fdalloc() indicates expansion is necessary, undo the
assignments we've done so far, expand, and retry the whole process.
- Once all file *'s have been assigned to slots, update the f_msgcount
and unp_rights counters.
- Right before we return, copy the temporary integer array to the message
buffer, and trim the length as before.
Note that once locking is added to the filedesc array, this entire
operation will be `atomic', in that the lock will be held while
file *'s are assigned to embryonic table slots, thus preventing anything
else from using them.
