thorpej | branches: 1.29.8;
Merge thorpej-cfargs branch:
Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.
Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)
Remove unnecessary or redundant interface attributes where they're not
needed.
There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

rumble | Fix comments about the cf_flags layout and use macros to test whether
tags, sync, and disconnect/reconnect are to be disabled or not.
|
| 1.15 |
| 21-May-2007 |
rumble | Check in a workaround before I lose or forget about it:
My SGI issued IBM DORS-32160 will respond to every message with a sync
negotiation (even IDENTIFY) until it gets a response it likes (and it
definitely doesn't like async). Unfortunately, this locks us into an endless
loop after sending IDENTIFY, since the device responds with a SYNC
negotiation that we refuse to accept. This refusal results in a new
target-initiated sync negotiation, and so on...
To work around this, permit negotiating sync mode on an unexpected
target-initiated sync negotiation.
|
| 1.14 |

rumble | Report whether we're using DMA and what type on attach, since I keep losing
track while testing.
|
| 1.13 |
| 08-May-2007 |
rumble | The maximum FIFO depth on old WD33C93 parts is only 5, not 12 as on 93A and
93B. However, there appear to be issues using the maximum of 5 on old
parts, so 4 is it.
|
| 1.12 |
| 08-May-2007 |
rumble | Enable Fast SCSI transfers for WD33C93B parts with appropriate input
clocks.
My Seagate ST32430N now sees about 50% greater throughput (about 97% as
fast as IRIX can push it). However, there appear to be other performance
issues with the driver as other disks perform significantly worse than they
should, with or without this change.
Reviewed by bjh21. Tested on my Indy and Challenge S.

Allow wd33c93 attachments to choose what DMA mode it should use, and arrange

bjh21 | Merge my bjh21-wd33c93 branch. This improves message handling in general
and sync negotiation in particular. Tested on sgimips (thanks to
Manuel Bouyer) and acorn26 (with my still-unfinished driver for the Acorn
SCSI Expansion Card).

Revert revision 1.4: it seems to have caused serious problems on sgimips,
so I should probably leave it until I get my Indy going.

bjh21 | Use symbolic names for CSR values after reset.
|
| 1.4 |
| 26-Aug-2006 |
bjh21 | When receiving a SCSI message, it's important not to deassert ACK on the last
byte until we've worked out what to do with the message, since if we plan
to reply to it we have to assert ATN before deasserting ACK. Implement this.
|

bjh21 | Use the 'z' size modifier when printfing size_t, so that GCC doesn't complain
on systems were size_t isn't unsigned int.

bjh21 | Move the sgimips "sbic" driver from arch/sgimips/hpc/sbic.c to
dev/ic/wd33c93.c. This may not be the best WD33C93 driver we've
got, but it's the most recently worked on and probably the most
portable, so it seems like a good basis for further work (and in
particular an acorn26 driver for the Acorn SCSI card). There's
no functional change in this commit, and sgimips kernels still
compile.

bjh21 | When reselecting a transfer that had DMA disabled, keep DMA disabled.
|
| 1.6.2.7 |
| 29-Aug-2006 |
bjh21 | Add support for negotiating async transfers if the scsipi layer asks for
that, or if the target requests sync transfers but the scsipi layer hasn't
turned them on yet. This is still some way from correctly implementing
the rules in SPI-5, but it's closer than it was.
|
| 1.6.2.6 |
| 29-Aug-2006 |
bjh21 | At the end of sync transfer negotiations, record the actual synchronous
transfer agreement that's been reached, rather than rounding it up to
the next transfer period we can support. This is particularly important
for target-initiated negotiations, since otherwise it might end up
transmitting at a lower than necessary rate.
Also, if we've agreed on sync transfer, don't silently try to use async
transfers just because the transfer period we've negotiated is a bit long.
It's possible we should renegotiate async transfers at that point, but for
now we'll just put up with it.
|
| 1.6.2.5 |
| 29-Aug-2006 |
bjh21 | Add a couple of debugging messages for tracing transfer mode discussions
with the scsipi layer.
|
| 1.6.2.4 |
| 28-Aug-2006 |
bjh21 | Print the attachment message in the attach routine rather than in the bus
reset routine. This should avoid getting odd messages when things go badly
wrong. While I'm there, re-arrange the attach message a bit (to look more
like the NCR53C9x one) and add the clock frequency to it.
|
| 1.6.2.3 |
| 28-Aug-2006 |
bjh21 | Ignoring WDTR IN is rude. Respond instead with MESSAGE REJECT OUT, like
any good initiator should.
|
| 1.6.2.2 |
| 28-Aug-2006 |
bjh21 | Rather than doing lots of sums every time we need to convert between
SCSI transfer period factors and WD33C93 TPx bits, build a little lookup
table of the available TPFs at startup and use that. This is rather
easier to understand than the old way.
Connectedly, remove code that tested for sc_minsync==0, since that couldn't
reasonably be true. Clients can use cf_flags to disable sync negotiation
if necessary.
|
| 1.6.2.1 |
| 28-Aug-2006 |
bjh21 | Reinstate my changes to the message-handling code, ensuring that we don't
release ACK until after we've decided whether we need to reply to a message,
since if we reply, we have to assert ATN before releasing ACK.
