5d57194434 Spring MegaChange #1.
----

Make a device for each ISP- really usable only with devfs and add an ioctl
entry point (this can be used to (re)set debug levels, reset the HBA,
rescan the fabric, issue lips, etc).

----

Add in a kernel thread for Fibre Channel cards. The purpose of this
thread is to be woken up to clean up after Fibre Channel events
block things.  Basically, any FC event that casts doubt on the
location or identify of FC devices blocks the queues. When, and
if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED
async event, we activate the kthread which will then, in full thread
context, re-evaluate the local loop and/or the fabric. When it's
satisfied that things are stable, it can then release the blocked
queues and let commands flow again.

The prior mechanism was a lazy evaluation. That is, the next command
to come down the pipe after change events would pay the full price
for re-evaluation. And if this was done off of a softcall, it really
could hang up the system.

These changes brings the FreeBSD port more in line with the Solaris,
Linux and NetBSD ports. It also, more importantly, gets us being
more proactive about topology changes which could then be reflected
upwards to CAM so that the periph driver can be informed sooner
rather than later when things arrive or depart.

---

Add in the (correct) usage of locking macros- we now have lock transition
macros which allow us to transition from holding the CAM lock (Giant)
and grabbing the softc lock and vice versa. Switch over to having this
HBA do real locking. Some folks claim this won't be a win. They're right.
But you have to start somewhere, and this will begin to teach us how
to DTRT for HBAs, etc.

--

Start putting in prototype 2300 support.  Add back in LIP
and Loop Reset as async events that each platform will handle.
Add in another int_bogus instrumentation point.

Do some more substantial target mode cleanups.

e9a2738ad1 Complete some Ansification. Check to make sure, in tdma_mk, that we won't
overflow the request queue. The reason we want to do this is that we
now push out completed CTIOs as we complete them- this gets the QLogic
working on them quicker. So we need to know whether we can put the entire
burrito out before we start.

We now support conjoint status with data for the last CTIO for both Fibre
Channel and SCSI. Leave the old code in place in case we need to go back
(minor 3 line ifdef).

Ultra-ultra important- *don't* set rq->req_seg_count for non-data
target mode requests in isp_pci_dmasetup. D'oh- this is actually
the tag value area for a CTIO. What *was* I thinking? Boy howdy
does both aic7xxx and sym get awfully unhappy when on reconnect
you give them a constant '1' for a tag value.

b72b15696c For parallel SCSI, let us now do status with the final CTIO. For the 1080,
I was hanging after sending a xfer CTIO and a status CTIO for a non-discon
INQUIRY- the xfer CTIO was returned as completed OK, but the status CTIO
was dropped on the floor. All the fields looked good. I don't know why
it got dropped. But allowing status to go back with data xfer seemed to
work. I also noticed that with a non-disconnecting command that the
firmware handle in the ATIO is zero- this leads me to believe that the
f/w really can only handle one CTIO at a time in the discon case, and
it had no idea what to do with the second (status) CTIO.

d8d5f2adc5 more 32 to 16 bit handle conversions 2001-03-04 18:42:51 +00:00
Matt Jacob
5f5aafe1fc Switch to using 16 bit handles instead of 32 bit handles.
This is a pretty invasive change, but there are three good
reasons to do this:

1. We'll never have > 16 bits of handle.
2. We can (eventually) enable the RIO (Reduced Interrupt Operation)
bits which return multiple completing 16 bit handles in mailbox
registers.
3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec
changed such that at_reserved (which was 32 bits) was split into
two pieces- and one of which was a 16 bit handle id that functions
like the at_rxid for Fibre Channel (a tag for the f/w to correlate
CTIOs with a particular command). Since we had to muck with that
and this changed the whole handler architecture, we might as well...

Propagate new at_handle on through int ct_fwhandle. Follow
implications of changing to 16 bit handles.

These above changes at least get Qlogic 1040 cards working in target
mode again. 1080/12160 cards don't work yet.

In isp.c:
Prepare for doing all loop management in outer layers.

6e5c5328c4 Eliminate the use of the getenv_int stuff we'd been using (with a bitmap
for selecting unit). Instead, use the resource hints mechanism.

One unfortunate situation here is that there is no resource_quad_value
function- which is what I needed for WWN boot time replacement. Worse-
you can't store the hint as just plain

hint.isp.0.nodewwn="0x50000000aaaa0001"

because this gets interpreted as an int- incorrectly because it can't
be converted to an int. I can't even get this as a string. To work
around this particular case for nodewwn && portwwn setting, this
rather grotesque form will be used:

hint.isp.0.nodewwn="w50000000aaaa0001"
hint.isp.0.portwwn="w50000000aaaa0002"

At the same time, if we have no hinted WWN, set the default WWN (which, btw,
gets overridden if the card has valid NVRAM, which is usual) to
0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9).

Eliminate more printf's and replace them either with device_printf or
isp_prt calls.

b9b599fe4c Shuffle around how we do isp_disable management- make sure we return 0 so
the unit number doesn't get reused.

Make sure that if we've compiled for ISP_TARGET_MODE we set the
default role to be ISP_ROLE_INITIATOR|ISP_ROLE_TARGET.

Do some misc other cleanups.

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

56aef50302 Clean up firmware load issues and remove darn near all config options.
Force alphas to prefer mem mapping as the default.

Basically, we have a pointer to a function which we can call which will
return us a pointer to firmware for the card we have. We call this function
(if it's non-NULL) with the address of our mdvec f/w pointer.

The way this works is that if ispfw (as a module or a static) is loaded,
it initializes the pointer in isp_pci, so we can call into to it to fetch
a pointer to a f/w set.

If ispfw is MOD_UNLOADed, it's retained a pointer to our mdvec f/w pointers,
which then get zeroed out so we don't have any references to data that's
now gone from kernel memory. Removing the f/w saves ~360KBytes.

Alas, there is no autounload mechanism that works for is here.
