Support added for controllers capable of multi reply queues.
The following are the modifications to the driver to support NUMA.
1) Create the new structure adapter_reply_queue to contain the reply queue
info for every msix vector. This object will contain a
reply_post_host_index, reply_post_free for each instance, msix_index, among
other parameters. We will track all the reply queues on a link list called
ioc->reply_queue_list. Each reply queue is aligned with each IRQ, and is
passed to the interrupt via the bus_id parameter.
(2) The driver will figure out the msix_vector_count from the PCIe MSIX
capabilities register instead of the IOC Facts->MaxMSIxVectors. This is
because the firmware is not filling in this field until the driver has
already registered MSIX support.
(3) If the ioc_facts reports that the controller is MSIX compatible in the
capabilities, then the driver will request for multiple irqs. This count
is calculated based on the minimum between the online cpus available and
the ioc->msix_vector_count. This count is reported to firmware in the
ioc_init request.
(4) New routines were added _base_free_irq and _base_request_irq, so
registering and freeing msix vectors were done thru simple function API.
(5) The new routine _base_assign_reply_queues was added to align the msix
indexes across cpus. This will initialize the array called
ioc->cpu_msix_table. This array is looked up on every MPI request so the
MSIxIndex is set appropriately.
(6) A new shost sysfs attribute was added to report the reply_queue_count.
(7) User needs to set the affinity cpu mask, so the interrupts occur on the
same cpu that sent the original request.

Add SFF-8485 v0.7 / SAS-1 smp-write-gpio register support to libsas.
Defer SAS-2 support unless/until it defines an sgpio interface.
Minimum implementation needed to get the lights blinking.
try_test_sas_gpio_gp_bit() provides a common method to parse the
incoming write data (raw bitstream), and the to_sas_gpio_gp_bit() helper
routine can be used as a basis for the set/clear operations for the
'read' implementation. Host implementations parse as many bits
(ODx.[012]) as are locally supported and report the number of registers
successfully written. If the submitted data overruns the internal
number of registers available report the write as a success with the
number of bytes remaining reported in ->resid_len.
Example (assuming an active backplane) set the "identify" pattern for
the first 21 devices:
smp_write_gpio --count=2 --data=92,49,24,92,24,92,49,24 -t 4 --index=1 /dev/bsg/sas_hostX

In an enclosure model where there are chaining expanders to a large body
of storage, it was discovered that libsas, responding to a broadcast
event change, would only revalidate the domain of first child expander
in the list.
The issue is that the pointer value to the discovered source device was
used to break out of the loop, rather than the content of the pointer.
This still remains non-compliant as the revalidate domain code is
supposed to loop through all child expanders, and not stop at the first
one it finds that reports a change count. However, the design of this
routine does not allow multiple device discoveries and that would be a
more complicated set of patches reserved for another day. We are fixing
the glaring bug rather than refactoring the code.

This patch does several things:
- introduces __ethtool_get_settings which is called from ethtool code and
from drivers as well. Put ASSERT_RTNL there.
- dev_ethtool_get_settings() is replaced by __ethtool_get_settings()
- changes calling in drivers so rtnl locking is respected. In
iboe_get_rate was previously ->get_settings() called unlocked. This
fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same
problem. Also fixed by calling __dev_get_by_index() instead of
dev_get_by_index() and holding rtnl_lock for both calls.
- introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create()
so bnx2fc_if_create() and fcoe_if_create() are called locked as they
are from other places.
- use __ethtool_get_settings() in bonding code

For Target Portal Group IDs occupying the full 2 bytes in the

routine always fails in scsi_dh_alua.c:
if (h->group_id == (ucp[2] << 8) + ucp[3]) {
This causes the ALUA handler to wrongly identify the AAS of
a specified device as well as incorrectly interpreting the
supported AAS of the target as seen by the following entries
in the /var/log/messages:
"alua: port group 3ea state A supports tousna"
"alua: port group 3e9 state A supports tousna"

->queuecommand must return either 0, or one of the SCSI_MLQUEUE_* return

convention. Note that the DID_ERROR for returns from the low-level driver
might not be correct for all cases, but it's the best we can do with

Current fc_eh_host_reset leaves lport offline

The Marvell Universal Message Interface (UMI) defines a messaging
interface between host and Marvell products (Plato, for example). It
considers situations of limited system resource and optimized system
performance.
UMI driver translates host request to message and sends message
to FW via UMI, FW receives message and processes it, then sends response
to UMI driver.
FW generates an interrupt when it needs to send information or

1. Remove device database entry (ddb) state.
2. Remove device database (DDB) list building.
With open-iscsi integration the logins to the target devices are
handled by the user space. So the information of target is now
maintained in the iscsi_session object. This is handled at
libiscsi level so there is no need to maintain a list of DDBs in
the qla4xxx LLD.
3. qla4xxx: Remove add_device_dynamically.
Since autologin in FW is disabled with open-iscsi integration,
driver will never get an AEN for which driver has not requested
a DDB index. So remove the add_device_dynamically function.
4. Remove qla4xxx_tgt_dscvr
Since firmware autologin is disabled this function will not work.
Now user has the ability to do the target discovery and login to
each target individually. Firwmare will not do the login on its own.
5. Remove relogin related code
All relogin is handled by userspace now. qla4xxx just need to
notify userspace of a connection failure, this triggers the
relogin.
6. Remove add_session and alloc_session
Now qla4xxx uses iscsi_session_setup that would do the necessary
allocations for session and ddb_entry.

During kdump testing I noticed timeouts when initialising each IPR
adapter. While the driver has logic to detect an adapter in an
indeterminate state, it wasn't triggering and each adapter went
through a 5 minute timeout before finally going operational.
Some analysis showed the needs_hard_reset flag wasn't getting set.
We can check the reset_devices kernel parameter which is set by
kdump and force a full reset. This fixes the problem.

This fix:
- Disables app tag peeking; correct tag check will be added when the
SCSI API is available.
- Always derive ref_tag from scsi_get_lba()
- Removes incorrect swap of FCP_LUN in FCP_CMND
- Moves app-tag error check before ref-tag check. The reason being,
currently there is no interface in SCSI to retrieve the app-tag
for protection I/Os, so driver puts zero for app-tag in the
firmware interface, but requests not to validate it, but when a
ref-tag error is detected by firmware, it would put
expected/actual tags for all the protection tags (guard/app/ref).
As driver checks for app tag error first, a ref-tag error is
incorrectly flagged as app-tag error.
- Convert HBA specific checks to capability based.

Hardware allows both an outstanding number commands and a timeout value
(whichever occurs first) as a gate to the next interrupt generation. This
scheme at completion time looks at the remaining number of outstanding tasks
and sets the timeout to maximize small transaction operation. If transactions
are large (take more than a few 10s of microseconds to complete) then
performance is not interrupt processing bound, so the small timeouts this
scheme generates are overridden by the time it takes for a completion to
arrive.
