hscbs may be traded during error recovery due to the way

The pccard_function_init() call creates a bunch of inactive resources
that are persistant and configured on demand. When the child driver
"allocates" a resource it is connected up to one of these. When the
child releases the resource, we should not delete our copy, just
deactivate it again. Otherwise there is nothing to recreate it again
after several probe functions have run and done an alloc/release cycle.
INVARIANTS shows 0xdeadc0de without this.
More work is needed to do a sweep though the pccard_function_disable()
call to actually delete the resources for real. Right now, we leak
memory on eject (at best), so Dont Do That(TM) yet. This affects
16 bit pccards on a cardbus bridge only. This will be fixed soon, but

- Restructure so that we use a static pool of commands/FIBs, rather than
allocating them in clusters. The cluster allocation just made things

- Make queueing macros more like my other drivers. This adds queue stats

- Reimplement the periodic timeout scan. Kick the interrupt handler
and the start routine every scan as well, just to be safe. Track busy
commands properly.
- Bring resource cleanup into line with resource allocation. We should

This is because calls with M_WAIT (now M_TRYWAIT) may not wait
forever when nothing is available for allocation, and may end up
returning NULL. Hopefully we now communicate more of the right thing
to developers and make it very clear that it's necessary to check whether
calls with M_(TRY)WAIT also resulted in a failed allocation.
M_TRYWAIT basically means "try harder, block if necessary, but don't
necessarily wait forever." The time spent blocking is tunable with
the kern.ipc.mbuf_wait sysctl.
M_WAIT is now deprecated but still defined for the next little while.

* Fix some code that was actually passing the mbuf subsystem's M_WAIT to

aic7xxx_freebsd.h:
Softc storage for our event handler.
Null implementation for the ahc_platform_flushwork() OSM
callback. FreeBSD doesn't need this as XPT callbacks are
safe from all contexts and are done directly in ahc_done().
aic7xxx_inline.h:
Implement new lazy interrupt scheme. To avoid an extra
PCI bus read, we first check our completion queues to
see if any work has completed. If work is available, we
assume that this is the source of the interrupt and skip
reading INTSTAT. Any remaining interrupt status will be
cleared by a second call to the interrupt handler should
the interrupt line still be asserted. This drops the
interrupt handler down to a single PCI bus read in the
common case of I/O completion. This is the same overhead
as in the not so distant past, but the extra sanity of
perforning a PCI read after clearing the command complete
interrupt and before running the completion queue to avoid
missing command complete interrupts added a cycle.
aic7xxx.c:
During initialization, be sure to initialize all scratch
ram locations before they are read to avoid parity errors.
In this case, we use a new function, ahc_unbusy_tcl() to
initialize the scratch ram busy target table.
Replace instances of ahc_index_busy_tcl() used to unbusy
a tcl without looking at the old value with ahc_unbusy_tcl().
Modify ahc_sent_msg so that it can find single byte messages.
ahc_sent_msg is now used to determine if a transfer negotiation
attempt resulted in a bus free.
Be more careful in filtering out only the SCSI interrupts
of interest in ahc_handle_scsiint.
Rearrange interrupt clearing code to ensure that at least
one PCI transaction occurrs after hitting CLRSINT1 and
writting to CLRINT. CLRSINT1 writes take a bit to
take effect, and the re-arrangement provides sufficient
delay to ensure the write to CLRINT is effective. The
old code might report a spurious interrupt on some "fast"
chipsets.
export ahc-update_target_msg_request for use by OSM code.
If a target does not respond to our ATN request, clear
it once we move to a non-message phase. This avoids
sending a MSG_NOOP in some later message out phase.
Use max lun and max target constants instead of
hard-coded values.
Use softc storage built into our device_t under FreeBSD.
Fix a bug in ahc_free() that caused us to delete
resources that were not allocated.
Clean up any tstate/lstate info in ahc_free().
Clear the powerdown state in ahc_reset() so that
registers can be accessed.
Add a preliminary function for pausing the chip and
processing any posted work.
Add a preliminary suspend and resume functions.
aic7xxx.h:
Limit the number of supported luns to 64. We don't
support information unit transfers, so this is the
maximum that makes sense for these chips.
Add a new flag AHC_ALL_INTERRUPTS that forces the
processing of all interrupt state in a single invokation
of ahc_intr(). When the flag is not set, we use the
lazy interrupt handling scheme.
Add data structures to store controller state while
we are suspended.
Use constants instead of hard coded values where appropriate.
Correct some harmless "unsigned/signed" conflicts.
aic7xxx.seq:
Only perform the SCSIBUSL fix on ULTRA2 or newer controllers.
Older controllers seem to be confused by this.
In target mode, ignore PHASEMIS during data phases.
This bit seems to be flakey on U160 controllers acting
in target mode.
aic7xxx_pci.c:
Add support for the 29160C CPCI adapter.
Add definitions for subvendor ID information
available for devices with the "9005" vendor id.
We currently use this information to determine
if a multi-function device doesn't have the second
channel hooked up on a board.
Add rudimentary power mode code so we can put the
controller into the D0 state. In the future this
will be an OSM callback so that in FreeBSD we don't
duplicate functionality provided by the PCI code.
The powerstate code was added after I'd completed
my regression tests on this code.
Only capture "left over BIOS state" if the POWRDN
setting is not set in HCNTRL.
In target mode, don't bother sending incremental
CRC data.
This sould make the system power-off correctly where the howto had
more bits set than RB_POWEROFF, e.g. RB_NOSYNC.
