- Added 4 speaker enable to initialization sequence.
- Removed delays between register pokes which appear to aggravate a
problem this card has sampling at 44.1kHz. With any form of delay,
skew relative to system clock at 44.1kHz is usually in range 0-25%
(now 0-3%). No other rates exhibit this problem.
- Changed structs cmi_* to sc_*.

The names imply what they do. The last commit by DES based on a PR defeated
the original idea behind NO_MAKEDEV, which was not to run MAKEDEV, but to do
the installation of MAKEDEV. This should satisfy both parties on the MAKEDEV

Reflect this in mergemaster, this might later on be decided to be set to
NO_MAKEDEV_INSTALL, for now I kept to the old behaviour.

Fixed bitrot in prototype for mtx_init().
aic7xxx_pci.c:
Enable board generation of interrupts only once our handler is
in place and all other setup has occurred.
aic7xxx.c:
More conversion of data types to ahc_* names. tmode_tstate and
tmode_lstate are the latest victims.
Clean up the check condition path by branching early rather
than indenting a giant block of code.
Add support for target mode initiated sync negotiation.
The code has been tested by forcing the feature on for
all devices, but for the moment is left inaccesible until
a decent mechanism for controlling the behavior is complete.
Implementing this feature required the removal of the
old "target message request" mechanism. The old method
required setting one of the 16 bit fields to initiate
negotiation with a particular target. This had the nice
effect of being easy to change the request and have it
effect the next command. We now set the MK_MESSAGE bit
on any new command when negotiation is required. When
the negotiation is successful, we walk through and clean
up the bit on any pending commands. Since we have to walk
the commands to reset the SCSI syncrate values so no additional
work is required. The only drawback of this approach is that
the negotiation is deferred until the next command is queued to
the controller. On the plus side, we regain two bytes of
sequencer scratch ram and 6 sequencer instructions.
When cleaning up a target mode instance, never remove the
"master" target mode state object. The master contains
all of the saved SEEPROM settings that control things like
transfer negotiations. This data will be cloned as the
defaults if a target mode instance is re-instantiated.
Correct a bug in ahc_set_width(). We neglected to update
the pending scbs to reflect the new parameters. Since
wide negotiation is almost always followed by sync
negotiation it is doubtful that this had any real
effect.
When in the target role, don't complain about
"Target Initiated" negotiation requests when an initiator
negotiates with us.
Defer enabling board interrupts until after ahc_intr_enable()
is called.
Pull all info that used to be in ahc_timeout for the FreeBSD
OSM into ahc_dump_card_state(). This info should be printed
out on all platforms.
aic7xxx.h:
Add the SCB_AUTO_NEGOITATE scb flag. This allows us to
discern the reason the MK_MESSAGE flag is set in the hscb
control byte. We only want to clear MK_MESSAGE in
ahc_update_pending_scbs() if the MK_MESSAGE was set due
to an auto transfer negotiation.
Add the auto_negotiate bitfield for each tstate so that
behavior can be controlled for each of our enabled SCSI
IDs.
Use a bus interrupt handler vector in our softc rather
than hard coding the PCI interrupt handler. This makes
it easier to build the different bus attachments to
the aic7xxx driver as modules.
aic7xxx.reg:
Remove the TARGET_MSG_REQUEST definition for sequencer ram.
aic7xxx.seq:
Fix a few target mode bugs:
o If MK_MESSAGE is set in an SCB, transition to
message in phase and notify the kernel so that
message delivery can occur. This is currently
only used for target mode initiated transfer
negotiation.
o Allow a continue target I/O to compile without
executing a status phase or disconnecting. If
we have not been granted the disconnect privledge
but this transfer is larger than MAXPHYS, it may
take several CTIOs to get the job done.
Remove the tests of the TARGET_MSG_REQUEST field in scratch ram.
aic7xxx_freebsd.c:
Add support for CTIOs that don't disconnect. We now defer
the clearing of our pending target state until we see a
CTIO for that device that has completed sucessfully.
Be sure to return early if we are in a target only role
and see an initiator only CCB type in our action routine.
If a CTIO has the CAM_DIS_DISCONNECT flag set, propogate
this flag to the SCB. This flag has no effect if we've
been asked to deliver status as well. We will complete
the command and release the bus in that case.
Handle the new auto_negotiate field in the tstate correctly.
Make sure that SCBs for "immediate" (i.e. to continue a non
disconnected transaction) CTIO requests get a proper mapping
in the SCB lookup table. Without this, we'll complain when
the transaction completes.
Update ahc_timeout() to reflect the changes to ahc_dump_card_state().
aic7xxx_inline.h:
Use ahc->bus_intr rather than ahc_pci_intr.
I've left out a couple of unused args between internal functions.
Use MAXPATHLEN, not MAXPATHLEN + 1 in a couple of places.
Pass a pointer to the end of the target filename space.
two subject ucreds. Unlike p_cansee(), u_cansee() doesn't have
process lock requirements, only valid ucred reference requirements,
so is prefered as process locking improves. For now, back p_cansee()
into u_cansee(), but eventually p_cansee() will go away.

locks were held, we could be preempted and switch CPU's in between the time
that we set a variable to the list of spin locks on our CPU and the time
that we checked that variable to ensure no spinlocks were held while
grabbing a sleep lock. Losing the race resulted in checking some other
CPU's spin lock list and bogusly panicing.
