Log:
aic7xxx.c:
Use the target offset rather than the target Id to reference
the untagged SCB array. The offset and id are identical save
in the twin channel case. This should correct several issues
with the 2742T.
Set the user and goal settings prior to setting the current
settings. This allows the async update routine to filter out
intermediate transfer negotiation updates that may be less
than interesting. The Linux OSM uses this to reduce the amount
of stuff printed to the console.
aic7xxx.seq:
Correct an issue with the aic7770 in twin channel mode.
We could continually attempt to start a selection even
though a selection was already occurring on one channel.
This might have the side effect of hanging our selection
or causing us to select the wrong device.
While here, create a separate polling loop for when we
have already started a selection. This should reduce
the latency of our response to a (re)selection. The diffs
look larger than they really are due to some code rearrangement
to optimize out a jmp.
aic7xxx_freebsd.c:
Use the target offset rather than the target Id to reference
the untagged SCB array. The offset and id are identical save
in the twin channel case. This should correct several issues
with the 2742T.
aic7xxx_inline.h:
Get back in sync with perforce revision ID.
aic7xxx_pci.c:
Identify adapters in ARO mode as such.
Ensure that not only the subvendor ID is correct (9005)
but also that the controller type field is valid before
looking at other information in the subdevice id. Intel
seems to have decided that their subdevice id of 8086
is more appropriate for some of their MBs with aic7xxx
parts than Adaptec's sanctioned scheme.
Add an exclusion entry for SISL (AAC on MB based adapters).
Adapters in SISL mode are owned by the RAID controller, so
even if a driver for the RAID controller is not present,
it isn't safe for us to touch them.
