Tom: I did not commit a couple of your changes.
i did not include some punctuation fixes (full stops, etc.)
mnemorable -> mnemonic: i decided memorable was probably better
instrunctions -> instruction: i kept the plural

1) Eliminate some magic numbers.
2) Eliminate some double semi-colons.
3) Rename iha_scsi_req_q to iha_scb.

1) Return XS_DRIVER_STUFFUP if request sense cannot be loaded.
2) Try to avoid bus_dmamap_unload()'ing maps that have already been
unloaded.
3) Try to avoid bus_dmamap_load()'ing maps that are loaded.
4) Be extra paranoid and ensure bus_dmamap_sync()'s are done before
a bus_dmamap_unload().

1) Actually map and sync scatter gather list that is also DMA'd.
2) Actually map and sync request sense buffer.
3) Actually POSTREAD/WRITE sync data buffer after I/O, rather than
skipping it because the I/O was successful and no chars were left to
xfer.
4) Eliminate extra fields, clarify some names, reorder fields to
clarify their use.
5) Put common scatter gather preparation logic into separate function.
6) If insertion of request sense command fails, complete active
command with XS_SENSE, but zero'd sense data.
7) Eliminate physical address arithmetic as much as possible,
centralizing remaining manipulations in code actually sending
addresses to adapter.

Put debug messages in #ifdef sections.
Eliminate a less than useful error message.

osiop.
1) bus_dmamap_sync(POSTREAD) the request sense buffer *before* copying
it to xs->sense.
2) Always terminate timeout on completion of command, starting new one
for any REQUEST SENSE that is issued for non-polling commands.
3) Use pScb->SCB_Flags rather than xs->flags to ensure correct flags
are used during REQUEST_SENSE processing.
4) bzero() sense buffer before reading data into it.
This fixes a long standing problem where my Yamaha SCSI CD reported
bogus errors during probe.

when running a DIAGNOSTIC kernel. This was exposed by the recent
migration of the SCSI layer to use pools.
timeout_del() was being called on de-allocated memory after every
completed SCSI command. Which worked as long as the memory was not
reused or zapped ...
This patch, slightly modified from Andreas's original diff, moves
the timeout_del() to before the call to scsi_done() which
de-allocates the memory holding the timeout. All scb's that start
a timeout go through this logic and have the timeout_del() called.

using *_bus_dmamap_sync() defines that are defined appropriately
depending on __HAS_NEW_BUS_DMAMAP_SYNC.
Most of the code changes are simple reversions to the original NetBSD
code.
Slip in a siop_script_sync() instead of a manually done code section.

actually supported.
Update copyright to include 2001.
Fold iha_se2_rd_all() into iha_read_eeprom(), eliminating magic number
31 at the same time, calculating correct offset of checksum at run
time instead.
Eliminate static global variable iha_nvram in favour of dynamic
variable in iha_init_tulip(), which is only place it is used.
Rectify a few typos in comments.

preferences.
Rename tul_* functions/variables iha_* for consistancy, since all are
now visible.
As updating the EEPROM did not work, don't try. Remove now unused
static dftNvram variable, and functions used only in trying to write
it to EEPROM.
Make iha_rate_tbl a const.

Rename some functions for better consistancy/clarity, e.g.
tul_wdtr_done -> tul_wide_done
tul_msgout_wide -> tul_msgout_wdtr
Consolidate extended message generation into new function
tul_msgout_extended() by using HCS_Msg[] array, replacing
several repetitive bus_write_*() code sections.
A couple of minor code clarifications to eliminate extra
return statements and make absolutely sure HCS_ActScb is
NULL during a reselect.

wide is not.
Now my CD drives on the narrow channel of the INI-9100UW negotiate to
the same configuration they do on other cards.
|

negotiation results on one line, during boot polling only, in same
format as now used in siop.
Move checking for probe INQUIRY commands to poll loop rather than
checking every good I/O.
Remove an unwanted debug statement and unneeded (resolved) XXX
comment.
