2eaa80698f Add a missing pair of curly braces to a conditional debug
statement.  This ensures that debug code doesn't trigger if
it isn't enabled. <blush>

6cfbfac6d4 Add "missing scratch-pad register" to the first of the two ports
on the Argosy SP-320 dual-port async PCcard.

An amazing piece of hardware seen from an ISO9000 point of view.

97c6f4f976 Add yet a quick flag to sio: 0x100000 "Scratch pad register missing".
The advanced stage of computer assisted hardware design and
verification is aptly illustrated by the fact that this is necessary
because only the first ports in a single-chip, dual-port async
PC-Card product lacks this register.

3d3816e633 Extensively rework the geom_bsd method, put a lot of comments in, betting
that this will make people use this for their future copy&paste operations.

Rework the detection of raw-disk offsets in disklabels.  This actually
unearthed a number of bugs in the (now) previous version.

Also accept labels which don't have a magic RAW_PART, provided they don't
confuse us too much.

Change the order of our sanity-checks on labels found on disks to be more
robust.

Check against MAXPARTITIONS in our sanity-check and reject disklabels
we cannot cope with.

Create new g_bsd_modify() function to implment disklabel modifying
ioctls.

Implement DIOCSDINFO and DIOCWDINFO with the provision that the latter
still not writes your change back to disk.  I didn't have the nerves
for that yet.

In the start routine, use g_call_me() for complex ioctls to prevent
sleeping.

5a6baf5457 Add the new g_slice_config() call, which can add/delete/change a slice,
with support for trying, doing and forcing.

This will eventually replace g_slice_addslice() which gets changed from
grabbing topology to requing it in this commit as well.

b1937dd1ca Make the UP/DOWN threads hold on to their own private mutex while doing
work.

This prevents people from sleeping in the UP/DOWN I/O path by mistake
or design (doing so almost invariably result in deadlocks since it
stalls all I/O processing in the given direction.

d4c4a6f165 Setattr should not retry on EBUSY, we could get EBUSY back because
a disklabel modification tries to change an open device, and no
counter-examples exists.

Be less facist about when we can do Setattr, the openmodes of devices
are so loosely managed that the "exclusive" count is almost useless.

346cd5fe2d Implement g_call_me() as a way for geom methods to schedule operations
to be performed in the event-thread.

To do this, we need to lock the eventlist with g_eventlock (nee g_doorlock),
since g_call_me() being called from the UP/DOWN paths will not be able to
aquire g_topology_lock.

This also means that for now these events are not referenced on any
particular consumer/provider/geom.

For UP/DOWN path use, this will not become a problem since the access()
function will make sure we drain any bio's before we dismantle.

2e27173fb5 Add a D_NOGIANT flag which can be set in a struct cdevsw to indicate
that a particular device driver is not Giant-challenged.

SPECFS will DROP_GIANT() ... PICKUP_GIANT() around calls to the
driver in question.

Notice that the interrupt path is not affected by this!

This does _NOT_ work for drivers accessed through cdevsw->d_strategy()
ie drivers for disk(-like), some tapes, maybe others.

c59c8a72cf Upgrade to version 1.1 of the aic79xx U320 driver.
aic79xx.c:
	o Remove redundant ahd_update_modes() call.
	o Correct panic in diagnostic should state corruption cause
	  the SCB Id to be invalid during a selection timeout.
	o Add workaround for missing BUSFREEREV feature in Rev A silicon.
	o Corect formatting nits.
	o Use register pretty printing in more places.
	o Save and restore our SCB pointer when updating the waiting queue
	  list for an "expected" LQ-out busfree.
	o In ahd_clear_intstat, deal with the missing autoclear in the
	  CLRLQO* registers.
	o BE fixup in a diagnostic printf.
	o Make sure that we are in the proper mode before disabling
	  selections in ahd_update_pending_scbs.
	o Add more diagnostics.
	o task_attribute_nonpkt_tag -> task_attribute: we don't need a
	  nonpkt_tag field anymore for allowing all 512 SCBs to be
	  used in non-packetized connections.
	o Negotiate HOLD_MCS to U320 devices.
	o Add a few additional mode assertions.
	o Restore the chip mode after clearing out the qinfifo so that
	  code using ahd_abort_scbs sees a consistent mode.
	o Simplify the DMA engine shutdown routine prior to performing
	  a bus reset.
	o Perform the sequencer restart after a chip reset prior to
	  setting up our timer to poll for the reset to be complete.
	  On some OSes, the timer could actually pre-empt us and order
	  is important here.
	o Have our "reset poller" set the expected mode since there is
	  no guarantee of what mode will be in force when we are called
	  from the OS timer.
	o Save and restore the SCB pointer in ahd_dump_card_state().  This
	  routine must not modify card state.
	o Ditto for ahd_dump_scbs().

aic79xx.h:
	o Add a few more chip bug definitions.
	o Align our tag on a 32bit boundary.

aic79xx.reg:
aic79xx.seq:
	o Start work on removing workarounds for Rev B.
	o Use a special location in scratch from for stroring
	  our SCBPTR during legacy FIFO allocations.  This corrects
	  problems in mixed packetized/non-packetized configurations
	  where calling into a FIFO task corrupted our SCBPTR.
	o Don't rely on DMA priority to guarantee that all data in
	  our FIFOs will flush prior to a command completion notification
	  going out of the command channel.  We've never seen this assumption
	  fail, but better safe than sorry.
	o Deal with missing BUSFREEREV feature in H2A.
	o Simplify disconnect list code now that the list will always
	  have only a single entry.
	o Implement the AHD_REG_SLOW_SETTLE_BUG workaround.
	o Swith to using "REG_ISR" for local mode scratch during
	  our ISR.
	o Add a missing jmp to the data_group_dma_loop after our
	  data pointers have been re-initialized by the kernel.
	o Correct test in the bitbucket code so that we actually
	  wait for the bitbucket to complete before signaling the
	  kernel of the overrun condition.
	o Reposition pkt_saveptrs to avoid a jmp instruction.
	o Update a comment to reflect that the code now waits for
	  a FIFO to drain prior to issuing a CLRCHN.

aic79xx_inline.h:
	o Remove unused untagged queue handling code.
	o Don't attempt to htole64 what could be a 32bit value.

aic79xx_pci.c:
	o Set additional bug flags for rev A chips.

203639c449 Apparently pxeboot passes in a mygateway of non-zero sin length
from DHCP in the event that no gateway is returned from DHCP, breaking
the assumption that we skip the routing insertion of the gateway
if the sin length is zero.  Check also for s_addr of 0 to avoid the
"Oh no, adding my default route failed" panic, making it possible
to pxeboot machines on segments without default routes.  Arguably
this could be a bug in pxeboot, or in the TUNABLE code, but this
makes my boxes boot.
