cbc8eb67da [SCSI] qla2xxx: Fallback to 'golden-firmware' operation on supported ISPs.
In case the onboard firmware is unable to be read or loaded for
operation, attempt to fallback to a limited-operational firmware
image stored in a different flash region.  This will allow a user
to reflash and correct a board with proper operational firmware.

24a081386e [SCSI] qla2xxx: Explicitly set the execution-throttle with recent ISPs.
Firmware semantics changed for 24xx and above ISPs in their
handling of the specified execution-throttle passed during
firmware initialization.  The original codes use of a theoretical
maximum (0xffff, as carried over from earlier ISPs) could in fact
act as a throttle in some circumstances.  Now set the value based
of the firmware's own 'resource' (exchange IOCBs) capabilities.

d743de6675 [SCSI] qla2xxx: Reduce request queue-size overhead with recent ISPs.
The original code to 'resize request-queues' based on iocb-counts
and employed during early ISP23xx testing was too
overly-pessimistic with regards to latencies in the firmware
pulling requests.  Recent ISPs can easily keep up processing a
stream of commands from an abbreviated (effectively, half the

The original code would incorrectly hardcode ELS timeout values

FCE support enables the firmware to record FC extended link

view of the FC traffic through the ISP without using a FC
analyzer.  This can be useful in situations where a physical
connection to the FC bus is not possible.

The driver exports this information in two ways -- first, via a
debugfs node exported for all supported ISPs under:

	<debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce

where a read of the 'fce' file will provide a snapshot of the
firmware's FCE buffer; and finally, the FCE buffer will be
extracted during a firmware-dump scenario.

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

d19044c32b [SCSI] qla2xxx: defer topology discovery to DPC thread during initialization.
Modify intialization semantics:

- perform basic hardware configuration only (as usual)
  - allocate resources
  - load and execute firmware

- defer link (transport) negotiations to the DPC thread
  - again the code in qla2x00_initialize_adapter() to stall probe()
    completion was needed for legacy-style scanning.
  - DPC thread stalls until probe() complete.

- before probe() completes, set DPC flags to perform loop-resync logic
  (similar to what's done during cable-insertion/removal).

Benefits: user does not have to wait 20+ seconds in case the FC cable
is unplugged during driver load, code consolidation (removal of
redundant link negotiation logic during initialize_adaoter()), and
finilly, the driver no longer needs to defer the fc_remote_port_add()
calls to hold off lun-scanning prior to returning from the probe()
function.

In order to ensure that the workaround succeeded the driver

attempts a shutdown-retry after resetting the ISP and

d7a297baa6 [PATCH] fix qla{2,4} build error
commit 0181944fe6 adds a
'extended_error_logging' global variable to qla2xxx which is defined by
qla4xxx too.

Trying to build both drivers results in the following error:

  LD      drivers/scsi/built-in.o
  drivers/scsi/qla4xxx/built-in.o: In function `qla4xxx_slave_configure':
  drivers/scsi/qla4xxx/ql4_os.c:1433: multiple definition of `extended_error_logging'
  drivers/scsi/qla2xxx/built-in.o:drivers/scsi/qla2xxx/qla_os.c:2166:
  first defined here
  make[2]: *** [drivers/scsi/built-in.o] Error 1
  make[1]: *** [drivers/scsi] Error 2
  make: *** [drivers] Error 2

The following patch simply adds a qla2_ (qla4_ respectively) prefix to
the variable name.

d8b4521349 [SCSI] qla2xxx: Add iIDMA support.
iIDMA (Intelligent Interleaved Direct Memory Access) allows for
the HBA hardware to send FC frames at the rate at which they can
be received by a target device.  By taking advantage of the
higher link rate, the HBA can maximize bandwidth utilization in a
heterogeneous multi-speed SAN.

Within a fabric topology, port speed detection is done via a Name
Server command (GFPN_ID) followed by a Fabric Management command
(GPSC).  In an FCAL/N2N topology, port speed is based on the HBA
link-rate.

removal of the device to the default workqueue.  If the
work-item was preceded by an event which caused the port to
obtain visibility (relogin successful, target re-logged into
the topology), deferred removal could inadvertently drop the
rport.  The code also no longer defers removal via the
default workqueue, instead opting for use of the driver's
own DPC thread.

19a7b4aebf [SCSI] update fc_transport for removal of block/unblock functions
We recently went back to implement a board reset. When we perform the
reset, we wanted to tear down the internal data structures and rebuild
them. Unfortunately, when it came to the rport structure, things were
odd. If we deleted them, the scsi targets and sdevs would be
torn down. Not a good thing for a temporary reset. We could block the
rports, but we either maintain the internal structures to keep the
rport reference (perhaps even replicating what's in the transport),
or we have to fatten the fc transport with new search routines to find
the rport (and deal with a case of a dangling rport that the driver
forgets).

It dawned on me that we had actually reached this state incorrectly.
When the fc transport first started, we did the block/unblock first, then
added the rport interface. The purpose of block/unblock is to hide the
temporary disappearance of the rport (e.g. being deleted, then readded).
Why are we making the driver do the block/unblock ? We should be making
the transport have only an rport add/delete, and the let the transport
handle the block/unblock.

So... This patch removes the existing fc_remote_port_block/unblock
functions. It moves the block/unblock functionality into the
fc_remote_port_add/delete functions.  Updates for the lpfc driver are
included. Qlogic driver updates are also enclosed, thanks to the
contributions of Andrew Vasquez. [Note: the qla2xxx changes are
relative to the scsi-misc-2.6 tree as of this morning - which does
not include the recent patches sent by Andrew]. The zfcp driver does
not use the block/unblock functions.

One last comment: The resulting behavior feels very clean. The LLDD is
concerned only with add/delete, which corresponds to the physical
disappearance.  However, the fact that the scsi target and sdevs are
not immediately torn down after the LLDD calls delete causes an
interesting scenario... the midlayer can call the xxx_slave_alloc and
xxx_queuecommand functions with a sdev that is at the location the
rport used to be. The driver must validate the device exists when it
first enters these functions. In thinking about it, this has always
been the case for the LLDD and these routines. The existing drivers
already check for existence. However, this highlights that simple
validation via data structure dereferencing needs to be watched.
To deal with this, a new transport function, fc_remote_port_chkready()
was created that LLDDs should call when they first enter these two
routines. It validates the rport state, and returns a scsi result
which could be returned. In addition to solving the above, it also
creates consistent behavior from the LLDD's when the block and deletes
are occuring.

4fdfefe529 [SCSI] qla2xxx: Add support to dynamically enable/disable ZIO.
ISP23xx and ISP24xx chips have support for an adaptive
method of posting SCSI command completions for multiple SCSI
commands during a single system interrupt.

SCSI commands are placed on the system response queue
without interrupting the host until 1) a delay timer
expires; or 2) a SCSI command completes with an error.

As long as the host software (qla2xxx) services the response
queue for completions (this polling is done during
queuecommand()) within the 'delay timer' period, the
firmware will not generate system interrupt.

27b2f6792f [PATCH] qla2xxx: Use dword accessors for PCI_ROM_ADDRESS
PCI_ROM_ADDRESS is a 32 bit register and as such should be accessed using
pci_bus_{read,write}_config_dword().  A recent audit of drivers/ turned up
several cases of byte- and word-sized accesses.  The harmful ones were fixed
by Linus directly.  This patches up one of the remaining
harmless-but-still-wrong cases caught in the dragnet.

f7d289f62e [SCSI] qla2xxx: Correct domain/area exclusion logic.
In an FL topology, limit port recognition to those devices
not within the same area and domain of the ISP.  The
firmware will recogonize such devices during local-loop
discovery.

Some devices may respond to a PLOGI before they have
completed their fabric login or they may not be a public
device. In this case they will report:

        domain == 00
        area == 00
        alpa == <XX>

which is valid. Exclude such devices from local loop
discovery.

77d7414361 [SCSI] qla2xxx: Cleanup FC remote port registration.
Cleanup FC remote port registration.

Due to the inherent behaviour (an immediate scan) of adding
a 'target'-role-capable rport via fc_remote_port_add(),
split the registration into two steps -- addition as
unknown-type role, then use fc_remote_port_rolchg() with
appropriate role (based on PLOGI/PRLI bits).  This allows
for a more cleaner rport->dd_data management as can be seen
with the simplified qla2xxx_slave_alloc() function.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
