Log:
adv_pci.c:
Update list of supported products.
Adjust probe message to include the ASC3030.
advansys.c:
Fix a long standing bug in the error recovery strategy. In order
to keep recovery simple, we freeze the SIMQ, stopping the XPT from
submitting new requests. Unfortunately, we also will freeze the
SIMQ if bus_dmamap_load blocks or we run out of controller resources.
On cards with limited resources it was possible to freeze the
SIM a second time and never unfreeze it. Now we more carefully
track our exception state so we never freeze the SIMQ more than
once.
Don't rely on pointers fitting in a 32bit field stored in the
per-transaction data structures on the card. Use an index to
an array of transaction mapping structures instead. This should
allow this driver to work on the Alpha.
Deal with the ASC3030 which is almost idistinguishable from the
ASC3050. Unfortunately the ASC3030 does not work at Ultra speeds,
so if we can't find an eeprom, we must assume that ultra is disabled.
The SIIG cards using the 3030 do not have eeproms. As a side effect,
we now honor the ultra disable bit in the eeprom if it is present.
Don't bother attempting to write corrected eeprom data back to the
eeprom. We can function just fine if the data is corrupted and
I'd rather not risk messing up the user's eeprom.
Modify the interrupt handler to catch latched external bus rests.
Dynamically determine the maximum number of S/G elements we can
map at a single time. The nature of the firmware interface for
these cards makes this value dependent on the number of "queues"
the card can support.
advlib.c:
advlib.h:
advmcode.c:
advmcode.h:
Synchronize with the latest firmware image released in the
Linux Advansys driver.
