Please move the host template to the C file instead of the header
if you touch it. Having them in the header and the methods exported
was needed in 2.2, but that's long ago..

At your service :-)
Except for the MIPS JAZZ driver, since SCSI_JAZZ_ESP is not actually used
anymore, probably due to bit rot.
Subject: [PATCH] NCR53C9x ESP: C99 designated initializers and host templates
NCR53C9x ESP:
- C99 designated initializers
- Move NCR53C9x ESP host templates from the header files to the source files.

The patch looks fine, thanks. Now if all scsi host driver maintainers
would do it this way.. :)

Next iteration (this replaces all 3 previous patches, which Linus didn't apply
anyway):
+ Move common NCR53C9x ESP prototypes from the host adapter-specific header
files to NCR53C9x.h
+ Move host adapter-specific definitions from the host adapter-specific
header files to the host adapter-specific source files
Full changeset log:
NCR53C9x ESP updates:
- Port 2.5.45 Sun/SPARC ESP SCSI driver changes to the NCR53C9x ESP SCSI
drivers
- C99 designated initializers
- Move NCR53C9x ESP host templates from the host adapter-specific header
files to the source files
- Move common NCR53C9x ESP prototypes from the host adapter-specific header
files to NCR53C9x.h
- Move host adapter-specific definitions from the host adapter-specific
header files to the host adapter-specific source files
This affects the following SCSI host adapters:
- Amiga Blizzard 1230IV, 1260, and 2060
- Amiga BSC Oktagon
- Amiga Cyberstorm and Cyberstorm II
- Amiga Phase 5 Fastlane
- DECstation NCR53C94
- JAZZ Fas216
- Mac 53C9x
- MCA 53C9x
- Sun-3x ESP

Reset is called with the lock held surely. How can the wait_event be

I don't know. I just ported the Sun/SPARC ESP SCSI driver changes in 2.5.45 to
the NCR53C9x ESP SCSI drivers. If you're right, the same bug is present in
esp.c.
Dave?
BTW, what about merging esp.c and NCR53C9x.c?

That's a little inconvenient.
I have to wait for an interrupt from the chip to know the RESET
started by the eh_reset_bus_handler code is done, and I'm certainly
not going to spin there for 5 seconds or however long it decides to
take. :-)
Either eh_reset_bus_handler needs to be allowed to sleep, or it needs
to be changed so that an "RESET in progress, please wait" status can
be returned.
Doug?
BTW, what about merging esp.c and NCR53C9x.c?
I don't have the time to abstract away all of the various DMA portion
of the ESP chip handling to allow that. There are 12 different
combinations of ESP + DMA controller combinations on Sparc, so if you
do the changes you'll need to test that :-)
Franks a lot,

The stupid thing is we take the lock then call the eh function then drop
it. You can drop the lock, wait and retake it. I need to fix a couple of
other drivers to do a proper wait and in much the same way.

Hmm.. I wonder if the thing should disable the queue (plug it) and release
the lock before calling reset. I assume we don't want any new requests at
this point anyway, and having the low-level drivers know about stopping
the queue etc sounds like a bad idea..
Of course, I suspect that it is potentially a bad idea to have the reset
functionality at the SCSI level _at_all_. As usual, the higher layers
don't really know what is going on, and the lower levels on smarter cards
are likely to be doing the right thing on their own, no?
(Yes, we should improve the infrastructure for having per-command timeouts
etc, but the reset/abort callbacks have always been strange)

something similar is needed in the scsi layer for other reasons too; I
can imagine something that behaves similar as the network layer's
netif_stop_queue() and allows drivers to inform the upper layer to stop
trying to submit requests to the lower level driver. Fiber channel
drivers can do this for example on LIP down (and enable again on LIP
up). LIP is not the only reason this is useful; overall I estimate that
over half of the code in the (out of tree) qlogic 2x00 driver can be
removed if this functionality was available.

We call into the driver with the lock held for the sake of consistency.
When you get right down to it, you can write a driver who has no more
concept of SMP locking than spin_lock_irq(host->host_lock); in the isr
routine. They need to know to drop the lock before calling scsi_sleep()
in the eh routines, or they can drop the lock and sleep on some wait queue
as well if they wish. But, in general, in depth locking knowledge is not
required. Since I've ported the old aic7xxx driver to the new scheme, it
is for certain an improvement over the old method in terms of ease of
programming a driver to the API.

Right, both already handled.

It saves a lot of code duplication. There's basically only two existing
reset strategies around. A) I'm a stupid card with a SCSI bus and all
SCSI busses and plain SCSI devices hang pretty much the same way, so the
mid layer can write a reasonable strategy routine and just have the low
level driver fill in the implementation hooks (abort hook, bus reset hook,
full host reset hook, etc) and B) I'm an intelligent firmware and you just
let me do my thing, in which case the mid layer can't really do anything
and the low level drivers only need to leave the hooks undefined because
if the firmware looses the command we're bust already.

Lower levels on smart cards assume that if the card ever looses a command
then you just want a watchdog to reset the machine anyway.

Yes, this part sucks. There needs to be an easy library function that
takes a scsi command pointer, sets up a wait queue, adds the wait queue
struct pointer to the scsi command, sleeps with a timeout, wakes up when
command completes via scsi_done() or timeout fires, returns value based
upon how wake up happened. Right now we don't have that, we only have a
little helper function, scsi_sleep(), for sleeping for a fixed length of
time.

I think you got it wrong.
The timer should be started when the command is started, not when it is
queued.
Just adding the command to the request queue and doing a wait-queue'd
"schedule_timeout()" is bad, because a previous (and unrelated command)
may be taking a long time, and may be delaying the new command which works
perfectly fine and returns immediately.
Example: somebody does a "close tray and read". Where it should be
perfectly possible to give the read command a short timeout, even if the
close tray takes a few seconds.
And btw, this has nothing to do with SCSI per se, so adding the thing to
the scsi command struct is bad, evil, and the reason for why the SCSI
mid-layers will eventually have to go away (ie they do exactly this kind
of thing, and _encourage_ people to do them).
We've got almost all of the infrastructure to do this on a request level
now, including the timeout value (but nothing that sets the timeouts for
regular IO).
We don't have the starting of the timer thing there, and that's at least
partly because I really think the timer should be started and set up by
the driver itself - and that's because only the driver can know if it can
actually remove the request and how to do it.
If the request ends up being pending and holding up other requests
(because the driver doesn't know how to physically abort it), we MUST NOT
return it as being "aborted due to timeout", because higher layers cannot
de-allocate the request anyway (imagine the thing later on waking up and
scribbling on memory that has now been free'd because the command "timed
out").
But yes, we want the infrastructure for doing this easily some day. As it
is, that's 2.7.x material by now.

Keep in mind that this is in eh context (from the original post). I'm not
talking about the queue path or normal case, only error recovery. For
example, in an abort handler, your driver can abort commands that haven't
made it to the drive yet immediately and return success. If the command
has already made it to the drive but hasn't been completed yet, then you
need to tell the drive to abort the command, not just do it. So,
currently, what I have to do in aic7xxx_abort() is actually requeue the
command to my card (this is OK, the card firmware does the right thing in
regards to finding an already active command on the incoming queue) but
this time with the abort message in the command message buffer. The card
starts device selection, the device responds, we send the IDENTIFY and
(possibly) TAG messages, followed by either ABORT or ABORT_TAG, device
then drops the bus to signify receipt of ABORT message. Fairly clean
process. The process can fail. If there is another command that is stuck
and holding the whole bus hostage, then our card won't be able to initiate
selection to the device. So, the only thing we can do is take a wait and
see attitude about whether or not the card can actually start the command
to the device and tell it to abort. In my driver now, I just drop the
lock and call scsi_sleep(HZ/4); (only need a very short timeout, if the
bus isn't hung then this completes fast, if it is hung, waiting doesn't
help), then check to see if my interrupt handler has completed the
command. Other drivers should wait significantly longer depending on
hardware. So, for me, the difference between scsi_sleep(HZ/4); or
something like scsi_sleep_until_done_with_timeout(cmd, HZ/4); is no big
deal, but I could see it making a lot of sense for other drivers (iSCSI,
other emulated drivers with fabrics, etc. come to mind). So, this becomes
a hook for "wake me up when this command makes it through to the normal
completion code".

Thats already being dealt with. The eh handler is a seperate thread
called after things are reasonably sane so that it can attempt recovery
and do so in a sleeping context if need be. The eh ones are actually
very except for the fact they take the lock before calling

I agree. You can simply drop the lock with no adverse consequences.

The queue doesn't need plugging, because only the error handler is a consumer
of this function (which stops the queue as it begins and restarts the queue
on exit). As Alan said, the lock stuff is a bit daft since the whole reason
the new eh came into being was to do this from a kernel thread so you could
sleep...

The API exists (scsi_block_requests, scsi_unblock_requests). It was
previously never really used because calling block_requests with no commands
outstanding hung the driver. However, this problem has been fixed.
The one thing this API doesn't do is stop timers on the outstanding commands,
but that could be done too, probably by a flag passed in.
