riastradh | Rename min/max -> uimin/uimax for better honesty.
These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.
HOWEVER! Some subsystems have
#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))
even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.
To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.
I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:
cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))
It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.
Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

Synchronize with other platforms:
Strongly architect handles so we can more easily detect bogus
handles. This switches us to a full 32 bits for all handles.
Handle the case of FC disks disappearing and then reappearing-
at least at the FC transport level.
Some better and finer control of debug and non-debug printouts.

Checkpoint of some fairly major isp(4) rototilling.
Reintroduce more of a 'channel' concept in preparation for NP-IV support.
This gets rid of the chanA/chanB concept as the 2400 can have up to 128
virtual channels. Actually, with MID firmware you can also have the 2200
and 2300 support 'channels, but they do it with an FL-Port topology.
Because FC cards can now have 'channels', just about every support
function for fibre channel had to be redone to have a channel index
as well. Rototill isp_ioctl.h for channel stuff as well.
Pick up a lot of work about fabric management (hopefully better) and keep
work in place that will allow for dynamic attachment/detachment of devices
(if I can figure out how to make the midlayer support it).
Merge the target code with external trees. Eventually it might even
be sorted out on NetBSD.
Update some firmware stuff.

mjacob | branches: 1.30.8; 1.30.24; 1.30.28;
Major update to isp(4) driver to bring it in line with external sources.
The major changes are:
+ 4Gb (24XX) card support
+ Rewritten fabric and loop evaluation code
+ New f/w sets
The 4Gb changes required major rototilling, which caused a rewrite of
fabric and loop eval code. The latter can now be set up to tune for
dynamic device arrival/departure if the framework is set up for it,
or to be firm about waiting for devices.
Testing has been principally on amd64, i386 and sparc64 and seems to
not have broken things for me.

Implement F/W crashdumps for 2200 && 2300 cards (kernel compile option).
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.

mjacob | Major restructuring for swizzling to the request queue and unswizzling from
the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have
a complete set of inline functions in isp_inline.h. Each platform is
responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32}
macros.
The reason this needs to be done is that we need to have a single set of
functions that will work correctly on multiple architectures for both little
and big endian machines. It also needs to work correctly in the case that
we have the request or response queues in memory that has to be treated
specially (e.g., have ddi_dma_sync called on it for Solaris after we update
it or before we read from it).
One thing that falls out of this is that we no longer build requests in the
request queue itself. Instead, we build the request locally (e.g., on the
stack) and then as part of the swizzling operation, copy it to the request
queue entry we've allocated. I thought long and hard about whether this was
too expensive a change to make as it in a lot of cases requires an extra
copy. On balance, the flexbility is worth it. With any luck, the entry that
we build locally stays in a processor writeback cache (after all, it's only
64 bytes) so that the cost of actually flushing it to the memory area that is
the shared queue with the PCI device is not all that expensive. We may examine
this again and try to get clever in the future to try and avoid copies.
Another change that falls out of this is that MEMORYBARRIER should be taken
a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the
entry being added. But there had been many other places this had been missing.
It's now very important that it be done.
For NetBSD, it does a ddi_dmamap_sync as appropriate. This gets us out of
the explicit ddi_dmamap_sync on the whole response queue that we did for SBus
cards at each interrupt.
Set things up so that platforms that cannot have an SBus don't get a lot of
the SBus code checks (dead coded out).
Additional changes:
Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry,
the iptr value that gets returned is the value we intend to eventually plug
into the ISP registers as the entry *one past* the last one we've written-
*not* the current entry we're updating. All along we've been calling sync
functions on the wrong index value. Argh. The 'fix' here is to rename all
'iptr' variables as 'nxti' to remember that this is the 'next' pointer-
not the current pointer.
Devote a single bit to mboxbsy- and set aside bits for output mbox registers
that we need to pick up- we can have at least one command which does not
have any defined output registers (MBOX_EXECUTE_FIRMWARE).
Explicitly decode GetAllNext SNS Response back *as* a GetAllNext response.
Otherwise, we won't unswizzle it correctly.
Nuke some additional __P macros.

Update from Matthew Jacob:
Correctly account for F-port vs. F-port (no FLOGI_ACC) topologies.
Make sure we get a port database entry for the fabric name server.
Preserve fabric logins if the device didn't change across fabric
or port database changes, or the device has already logged into
us (e.g., for target/initiator dual role devices like Veritas
SANbox). Propagate class 3 service parameter changes where devices
can change roles.
Fix all occurrences of setting a sendmarker so that setting it
for one bus on dual bus cards doesn't wipe a pending sendmarker
for other busses on the same card :-;.
Comments added and clarifications made in some of the target mode code.
