This removes 288KB (36%) of the driver code and zillions of hacks and workarounds, making single driver uniformly support several different generations of hardware interfaces, not counting minor card variations. After years of the hopeless fight, I don't think it worth to continue support for hardware obsolete for 15-20 years. Instead much cleaner now code should allow to move forward toward better locking, multiple queues and other cool features. All the remaining Qlogic cards starting from 4Gb 24xx to 32Gb 27xx use the same hardware/firmware interface with minor incremental improvements, so it seems to be a good new starting point. Except one PCI-X model all all of them are PCIe and so still usable in modern systems. Discussed with: ken, scottl, jpaetzel, imp Relnotes: yes

|
|
.Nd "Firmware for Qlogic FibreChannel SCSI Host Adapters"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device ispfw"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
ispfw_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
This trivial driver provides access to firmware sets for the Qlogic
|
|
FibreChannel SCSI Host Adapters.
|
|
It may either be
|
|
statically linked into the kernel, or loaded as a module.
|
|
In either
|
|
case, the
|
|
.Xr isp 4
|
|
driver will notice that firmware is available to be downloaded onto
|
|
Qlogic cards (to replace the usually out of date firmware on the cards).
|
|
This will kick the f/w into getting unstuck.
