[v2 PATCH 0/20][SCSI] mpt3sas: Driver submission v01.100.01.00
This is new scsi lld device driver from LSI supporting the SAS 3.0 standard. Here is list of new 12gb host controllers: LSI SAS3004 LSI SAS3008 LSI SAS3108 Here are the changes in the 2nd posting of this patch set: (1) Fix compile errors when SCSI_MPT3SAS_LOGGING is not enabled. (2) Set the task attribute field to "Simple" if the mpt3sas driver receives CDB with untagged task attribute field.

This patch checks whether HBA is SAS2008 B0 controller.
if it is a SAS2008 B0 controller then it use IO-APIC interrupt instead of MSIX,
as SAS2008 B0 controller doesn't support MSIX interrupts.

[RESEND] [PATCH] [SCSI] mptfusion: Fix for issue - The device is removed in blocked state
Fix for issue - The device is removed in blocked state.
The device is set to blocked state when I/Os running and the cable is pulled.
Also if the device missing delay timer is started. When the device missing
delay timer expires, the device is removed but the device state is not set to
unblocked state. This will cause problems if there are commands in block
queue.
To fix this issue, added code to unblock the device before removing it.

[PATCH 03/09] [SCSI] mpt2sas : Fix for Driver oops, when loading driver with max_queue_depth command line option to a very small value
If the specified max_queue_depth setting is less than the expected number of
internal commands, then driver will calculate the queue depth size to a negitive
number. This negitive number is actually a very large number because variable is
unsigned 16bit integer. So, the driver will ask for a very large amount of
memory for message frames and resulting into oops as memory allocation routines
will not able to handle such a large request.
So, in order to limit this kind of oops, The driver need to set the
max_queue_depth
to a scsi mid layer's can_queue value. Then the overall message frames required
for
IO is minimum of either (max_queue_depth plus internal commands) or the IOC
global
credits.

When device discovery is disabled during driver load time using module parameter
"disable_discovery=1" and when diag reset is issued then from logs, it is
observed
that the devices get added, removed and then added with new target ids.
So, inorder to limit this turn-off the code which is deleting and devices across

[PATCH 07/09] [SCSI] mpt2sas : Fix for staged device discovery functionality of driver not working
This patch provides a command line option to disable "Port enable" during
the driver load.
The objective of this command line option is to load the driver and do
all the necessary initialization excluding port enable(i.e. delay
device discovery)

[PATCH 04/09] [SCSI] mpt2sas : Provide sysfs attribute to report Backup Rail Monitor Status
A new sysfs shost attribute called "BMR_status" is implemented to
report Backup Rail Monitor status.
This attribute is located in the path
/sys/class/scsi_host/host#/BMR_status
when reading this adapter attribute, then driver will output the state
of GPIO[24]. It returns "0" if BMR is healthy and it returns "1" for failure.
if it returns an empty string then it means that there was an error while
obtaining the BMR status. Then check dmesg for what error has occured.
