SubjectVersion 6.1.6 of the aic7xxx driver availalbe
Date
From
As always, the latest version of this driver is availalbe here:

http://people.FreeBSD.org/~gibbs/linux/

Complete CHANGELOG is now available at the above URL.

I try to filter though LK as often as I can, but for
best response, please email issues regarding this driver to
me directly.

Changes since 6.1.5 include:

o Firmware generation is now a tunable option
defaulting to OFF. Don't turn this on unless
you really have a reason to re-agenerate the
firmware (e.g. you are actively developing it).

o aicasm Makefile changes from Alan Cox that
attempt to make aicasm compilable on more
distributions.

o On some chips, at least the aic7856, the transition from
MREQPEND to HDONE can take a full 4 clock cycles. Test
HDONE one more time to avoid this race. We only want our
FIFO hung recovery code to execute when the engine is
really hung. This makes the aic7856 work again on systems
affected by the PCI 2.1 retry bug.

o Modify our interrupt handler so that optimizations
that rely on level sensitive interrupts are disabled
when edge triggered interrupts are in use. This
affected the 284X and some EISA installations where
level sensitive interrupts are disabled.

o Staticize some rogue symbols. All exported symbols
have either an "ahc" or "aic7xxx" prefix to avoid
potential conflicts with other modules.

o Fix the sorting of driver instances so that even
if PCI devices are presented to the driver in a
very strange order, it still works. In the past,
we relied on function 0 of a device being seen prior
to function 1. This should make the channel b primary
BIOS option functional again.

o Add a crude hack to make modunload/modload cycles work
now that we are using the new PCI methods. We must
detach our driver from each PCI device referenced by
a call to our release method. The PCI code doesn't have
a method to do this, so we muck with the pci_dev ourselves.

o Deregister our PCI driver when aic7xxx_release releases
the last host instance.

o Only adjust our goal negotiation settings if the device
is actually present. This prevents a disconnected lun
that does not claim to support negotiations from messing
up the settings for a successfully probed lun whose inquiry
data properly reflects the abilities of the device.

o Set the device structure as releasable should the inquiry
come back with anything other than lun connected. We
should also do this if the device goes away as evidenced
by a selection timeout, but as we can't know if this
condition is persistant and there is no guarantee that
the mid-layer will reissue the inquiry command we use
to validate the device, I've simply added a comment
this effect.
