Distinguish between 2312 and 2300 cards (they *are* different). Enable
RIO (Reduced Interrupt Operation) for the LVD cards (hey- I've seen
batched completions of the 30 commands at a time with this,....)...
If we get a Port Logout on local loop topologies, we have to force the
f/w to log back in. The easiest way (for us) to do this is to force
a LIP. This also will wake up the disk that probably just had a f/w crash.
Implement mailbox 'continuations'- this allows interrupts to re-drive
a mailbox command if it's one that just essentially repeats the previous
mailbox command (e.g., f/w download). This saves a boatload of sleep/wakeup
twitches.
If we're not a 2300 and we're about to return with a 'bogus interrupt'- check
the semaphore register to be non-zero at all and outgoing mailbox 0- this
seems to be where some of the lost ISP1080 commands came from.
a byte-size quantity, the CacheLine Size configuration register specifies
the system cacheline size in units of 32-bit words; per PCI Local Bus
Specification, rev. 2.1, section 6.2.4.
NB: ebus_attach_args member names are singular to be consistent with SBus.
sparc64 version uses plural, so update sparc64 drivers when converting them
to use this shared header
pairs. Without this, the interrupt handler will steal the "command completed"
status and wi_cmd will busy loop until it times out.
Add some error output to make failure modes like this more prominent.
This should fix PR 14559.
in preparation for future mvmeppc and mvme88k ports.
This needs a bit if tidying up to make it trully shareable, which will
happen as the new mvme ports are added.
