Modify the manner in which we lock RAID-5 plexes. This appears to
solve some of the elusive panics we have seen with corrupted buffer
headers (specifically the zeroed-out b_iodone field).

drives. This function just does the low-level configuration changes;
the resultant subdisk is stale if it previously had any contents,
otherwise it is empty (i.e. in need of initializing if it's RAID-5).
We still need to handle getting the contents moved over, but the
current version will suffice to migrate subdisks from a disk which has
failed.

Kawasaki LSI KL5KUSB101B chip, including the LinkSys USB10T, the
Entrega NET-USB-E45, the Peracom USB Ethernet Adapter, the 3Com
3c19250 and the ADS Technologies USB-10BT. This device is 10mbs
half-duplex only, so there's miibus or ifmedia support. This device
also requires firmware to be loaded into it, however KLSI allows
redistribution of the firmware images (I specifically asked about
this; they said it was ok).
Special thanks to Annelise Anderson for getting me in touch with
KLSI (eventually) and thanks to KLSI for providing the necessary
programming info.
Highlights:
- Add driver files to /sys/dev/usb
- update usbdevs and regenerate attendate files
- update usb_quirks.c
- Update HARDWARE.TXT and RELNOTES.TXT for i386 and alpha
- Update LINT, GENERIC and others for i386, alpha and pc98
- Add man page
- Add module
- Update sysinstall and userconfig.c
has it blacklisted. Silly us for not planning ahead. Tsk. Anyway-
a 10 year window patch is probably sufficient to still detect
nonsense in the clock but allow us to roll past the year 2000.
code gratefully borrowed from Patrick Stirling who did a lot of the
grunt work on this years ago. There are also some beginnings of
swizzle macros in case we go to a big endian machine. This is just
a first pass at this and is likely to change a bit over the next
Add in a very large amount of target mode support code- this is just
a first pass at this. It's a difficult thing because some of the code
can be in platform independent areas (see isp_target.?) but a lot has
to be in platform dependent areas because of not only the tight coupling
of received commands/events and the specific OS subsystem but because
the platform independent code has (deliberately) no event/wait mechanisms.
of where we could have seen the loop up at least once so it
makes sense. Change some stuff in ispscsicmd so we don't get
stuck there if the loop has never come up yet. Add in some
target mode support code.
down, the dc driver and receiver can fall out of sync with one another,
resulting in a condition where the chip continues to receive packets
but the driver never notices. Normally, the receive handler checks each
descriptor starting from the current producer index to see if the chip
has relinquished ownership, indicating that a packet has been received.
The driver hands the packet off to ether_input() and then prepares the
descriptor to receive another frame before moving on to the next
descriptor in the ring. But sometimes, the chip appears to skip a
descriptor. This leaves the driver testing the status word in a descriptor
that never gets updated. The driver still gets "RX done" interrupts but
never advances further into the RX ring, until the ring fills up and the
chip interrupts again to signal an error condition. Sometimes, the
driver will remain in this desynchronized state, resulting in spotty
performance until the interface is reset.
Fortunately, it's fairly simple to detect this condition: if we call
the rxeof routine but the number of received packets doesn't increase,
we suspect that there could be a problem. In this case, we call a new
routine called dc_rx_resync(), which scans ahead in the RX ring to see
if there's a frame waiting for us somewhere beyond that the driver thinks
is the current producer index. If it finds one, it bumps up the index
and calls the rxeof handler again to snarf up the packet and bring the
driver back in sync with the chip. (It may actually do this several times
in the event that there's more than one "hole" in the ring.)
So far the only card supported by if_dc which has exhibited this problem
is a LinkSys LNE100TX v2.0 (82c115 PNIC II), and it only seems to happen
on one particular system, however the fix is general enough and has low
enough overhead that we may as well apply it for all supported chipsets.
I also implemented the same fix for the 3Com xl driver, which is apparently
vulnerable to the same problem.

o Add pcic_suspend/pcic_resume so we can detach our children on suspention
and fix the state of the pcic on resume.
o Remove some unused parts of softc.
o Centralize resource activation/deactivation for pcic bridge chip in
the stylistic pcic_activate/pcic_deactivate.
o Add bus_print_child method so we can see the pccard attachment.
o Add pcic_identify in an attempt to make it possible to automatically id
the pcic devices. This works great, but we cannot divine the irq to use
from this method, nor the memory hole. For the moment, KLUDGE irq to be
10 and memory hold to be 0xd0000.
o Loose the pnp probe stuff. This may be a big mistake, but it is easy
enough to add back later. I did this so the identify routines can do their
thing unmolested by pnp information. The whole identify thing may be a bad
idea to be ripped out later.
o change return type of pcic_intr to void, make it static and ripple
this through the code.
o Add explicit call to bus_generic_attach at the end of pcic_attach to
get any children probed/attached.
o add some comments about future directions/questionable things being
done at different layers, etc.
then invoke the children. As the value of HISR can be read
