Michael Reed 03cb3829e0 [SCSI] fusion: hold off error recovery while alternate ioc is initializing
After discussing this patch with LSI, I resubmitting with a recommended
40 second wait for the alternate ioc's initialization to complete.
--
Fusion FC chips are two function with some shared resources.  During
initialization of one function its driver inhibits the ability of the
other function's driver to allocate message frames by clearing its
"active" flag.  Should mid-layer error recovery be initiated for a
scsi command during this initialization (which can take up to 40 seconds)
error recovery will escalate to the level of host reset.  This host
reset might fail (as the other function is resetting) resulting in
all connected targets being taken offline.

This patch holds off mid-layer error recovery for up to 40 seconds
to permit initialization of the other function to complete.

Kashyap, Desai 65f89c2396 [SCSI] mptfusion: Added MPI_SCSIIO_CONTROL_HEADOFQ priority
There is a 'ioprio' field in the BIO and the Request structure.
check this priority field and set MPI_SCSIIO_CONTROL_HEADOFQ
to pass down I/O priority.
An enhancement to the LSI Disk Array Controller firmware is being
developed to look at the Head Of Queue bit to allow I/Os with the HOQ bit
set to be processed before I/Os which do not have the HOQ bit set.
In order to set the HOQ bit, the mpt fusion driver  needs to look at the
'ioprio' field in the request structure associated with the scsi command.

Anatolij Gustschin f1053a7ca9 [SCSI] mptsas: Fix issue with chain pools allocation on katmai
Since commit 9d2e9d66a3
mptsas driver fails to allocate memory for the MPT chain buffers
for second LSI adapter on PPC440SPe Katmai platform:
...
ioc1: LSISAS1068E B3: Capabilities={Initiator}
mptbase: ioc1: ERROR - Unable to allocate Reply, Request, Chain Buffers!
mptbase: ioc1: ERROR - didn't initialize properly! (-3)
mptsas: probe of 0002:31:00.0 failed with error -3

This commit increased MPT_FC_CAN_QUEUE value but initChainBuffers()
doesn't differentiate between SAS and FC causing increased allocation
for SAS case, too. Later pci_alloc_consistent() fails to allocate
increased chain buffer pool size for SAS case.

Provide a fix by looking at the bus type and using appropriate
MPT_SAS_CAN_QUEUE value while calculation of the number of chain
buffers.

Pravin Bathija e46b63b37c [SCSI] mpt fusion: Fix 32 bit platforms with 64 bit resources.
Powerpc 44x uses 36 bit real address while the real address defined in
MPT Fusion driver is of type 32 bit. This causes ioremap to fail and
driver fails to initialize. This fix changes the data types
representing the real address from unsigned long 32-bit types to
resource_size_t which is 64-bit. The driver has been tested, the disks
get discovered correctly and can do IO.

Mike Christie e881a172da [SCSI] modify change_queue_depth to take in reason why it is being called
This patch modifies scsi_host_template->change_queue_depth so that
it takes an argument indicating why it is being called. This will be
used so that if a LLD needs to do some extra processing when
handling queue fulls or later ramp ups, it can do so.

This is a simple port of the drivers setting a change_queue_depth
callback. In the patch I just have these LLDs adjust the queue depth
if the user was requesting it.

Kashyap, Desai 9766096d33 [SCSI] mptsas : FW event thread and scsi mid layer deadlock in SYNCHRONIZE CACHE command
Normally In HBA reset path MPT driver will flush existing work in current work
queue (mpt/0) . This is just a dummy activity for MPT driver point of
view, since HBA reset will turn off Work queue events.

It means we will simply returns from work queue without doing anything.
But for the case where Work is already done (half the way), we have to have
that work to be done.

Considering above condition we stuck forever since Deadlock in scsi midlayer
and MPT driver. sd_sync_cache() will wait forever since HBA is not in
Running state, and it will never come into Running state since
sd_sync_cache() is called from HBA reset context.
Now new code will not wait for half cooked work to be finished
before returning from HBA reset.

Once we are out of HBA reset, EH thread will change host state to running from
recovery and work waiting for running state of HBA will be finished.
New code is turning ON firmware event from another special work called
Rescan toplogy.

2. fault_reset_work_lock is not used anywhere. driver is using taskmgmt_lock
instead of fault_reset_work_lock.
3. setting pci_set_drvdata properly.
4. Ingore config request when IOC is in reset state.( ioc_reset_in_progress
is set).

Kashyap, Desai eedf92b998 [SCSI] mpt fusion: Rescan SAS topology added
1.) SAS topology Rescan is added. If Firmware is doing Reset and we get
Device add interrupt from Firmware, we will not receive it as part of Reset
is going ON. After Reset we will do special Rescan of SAS topology.
2.) Driver version changed from 3.04.08 to 3.04.09.

Added proper lock/unlock in mptsas_not_responding_devices() as per James'
comment.

Kashyap, Desai ea2a788de4 [SCSI] mpt fusion: rewrite of ioctl_cmds internal generated function
1) rewrite of ioctl_cmds internal generated function that issue commands to
firmware, porting them to be single threaded using the generic MPT_MGMT
struct. All wait Queues are replace by completion Queue.
2) added seperate callback handler for ioctl task managment
(mptctl_taskmgmt_reply), to handle command that timeout
3) rewrite mptctl_bus_reset
