errors that plagued those cards with XFree86 4.0. They have two memory
ranges as well as an IO port range to them. Also cleaned up the three
warning messages that I got, from inb(), outb() and linuxulator. Also, I
noticed that the DRI and Glide support for the Voodoo4 and 5 has been
placed upon linux.3dfx.com, too bad they haven't released the tech docs
yet. Apparently, they are still pushing glide for all of us, so I will try
and add support once those tech docs are up.
other systems.
o Normalize copyright text.
o Clean up probe code function interfaces by passing around a single
structure of common arguments instead of passing "too many" args
in each function call.
o Add support for the AAA-131 as a SCSI adapter.
o Add support for the AHA-4944 courtesy of "Matthew N. Dodd" <winter@jurai.net
o Correct manual termination support for PCI cards. The bit definitions
for manual termination control in the SEEPROM were incorrect.
o Add support for extracting NVRAM information from SCB 2 for BIOSen
that use this mechanism to pass this data to OS drivers.
o Properly set the STPWLEVEL bit in PCI config space based on the
setting in an SEEPROM.
o Go back to useing 32byte SCBs for all controllers. The current
firmware allows us to embed 12byte cdbs on all controllers in
a 32byte SCB, and larger cdbs are rarely used, so it is a
better use of this space to offer more SCBs (32).
o Add support for U160 transfers.
o Add an idle loop executed during data transfers that prefetches
S/G segments on controllers that have a secondary DMA engine
(aic789X).
o Improve the performance of reselections by avoiding an extra
one byte DMA in the case of an SCB lookup miss for the reselecting
target. We now keep a 16byte "untagged target" array on the card
for dealing with untagged reselections. If the controller has
external SCB ram and can support 64byte SCBs, then we use an
"untagged target/lun" array to maximize concurrency. Without
external SCB ram, the controller is limited to one untagged
transaction per target, auto-request sense operations excluded.
o Correct the setup of the STPWEN bit in SXFRCTL1. This control
line is tri-stated until set to one, so set it to one and then
set it to the desired value.
o Add tagged queuing support to our target role implementation.
o Handle the common cases of the ignore wide residue message
in firmware.
o Add preliminary support for 39bit addressing.
o Add support for assembling on big-endian machines. Big-endian
support is not complete in the driver.
o Correctly remove SCBs in the waiting for selection queue when
freezing a device queue.
o Now that we understand more about the autoflush bug on the
aic7890, only use the workaround on devices that need it.
o Add a workaround for the "aic7890 hangs the system when you
attempt to pause it" problem. We can now pause the aic7890
safely regardless of what instruction it is executing.
Clean up the comments related to the high speed
sync rate table for SPI.
scsi_message.h:
Bring in some SCSI3 message terminology. All SCSI2 names
are still preserved for backwards compatibility.
Bring back the CAM_NEGOTIATE ccb flag. This flag indicates
that SPI transfer negotiation should occur concurrently with the
execution of this CCB. The flag is not yet used by the XPT but
is required for proper support of multi-initiator configurations
where topology scans cannot rely on a bus reset to invalidate
prior negotiations.
cam_xpt.c:
Don't allow DT transmission rates to be specified for devices
that don't have the DT feature listed in their inquiry data.
allocate a short port range in some alpha configurations.

when we're done reading it (makes checking things easier).
Before calling isp_notify_ack make sure we're at RUNSTATE-
elsewise we can be responding to LIPs or SCSI bus resets
before we've finished some of the wiring.
we need a function that tells the Qlogic f/w that a target mode command
is done, so increase the resource count for that lun. Add in a timeout
function to kick the putback again if we fail to do it the first time (we
may not have the request queue space for ATIO push). Split the function
isp_handle_platform_ctio into two parts so that the timeout function for
the ATIO push or isp_handle_platform_ctio can inform CAM that the requested
CTIO(s) are now done.
Clean up (cough) residual handling. What we need for Fibre Channel
is to preserve the at_datalen field from the original incoming ATIO
so we can calculate a 'true' residual. Unfortunately, we're not
guaranteed to get that back from CAM. We'll *try* to find it hiding
in the periph_priv field (layering violation)- but if an ATIO was
passed in from user land- forget it. This means that we'll probably
get residuals wrong for Fibre Channel commands we're completing
with an error. It's too late to 4.1 release to fix this- too bad.
Luckily the only device we'd really care about this occurring on
is a tape device and they're still so rare as FC attached devices
that this can be considered an untested combination anyway.
Remove all CCINCR usage (resource autoreplenish). When we've proved
to ourself that things are working properly, we can add it back
in.
Make sure we propage 'suggested' sense data from the incoming ATIO
into the created system ATIO- and set sense_len appropriately.
Correctly propagate tag values.
Fall back to the model of generating (well, the functions in isp_pci.c
do the work) multiple CTIOs based upon what we get from XPT. Instead
of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then
to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed
to us from XPT, and if it implies that we have to generate extra
Qlogic CTIOs, so be it. This means that we have to wait until the
last CTIO in a sequence we generated completes before calling xpt_done.
Executive summary- target mode actually now pretty much works well
enough to tell folks about.
interfaces. The original resource_find() returned a pointer to an internal
resource table entry. resource_find_hard() dereferences the actual
passed in value (oops!) - effectively trashing random memory due to
the pointer being passed in with a random initial value.

The driver was originally written by Lennart Augustsson, but Mike Smith

This will be used in the reboot "reseeder", coming in another

your randomness is compromised; something like

of the 7.65 f/w (the dual-id and multi-id flavor)- the dual-id doesn't
