[mpt3sas driver 02/10] mpt3sas: Used IEEE SGL instead of MPI SGL while framing a SMP Passthrough request message.

2016-01-27 Thread Suganath prabu Subaramani 
From: Suganath prabu Subramani 

As driver was using MPI SGL while framing the SMP Passthrough request
message due to which firmware unable to post the Reply Data in the host
memory and timeout is observed for this SMP Passthrough request message
and so unable to perform phy disable operation.

[mpt3sas driver 04/10] mpt3sas: Never block the Enclosure device

2016-01-27 Thread Suganath prabu Subaramani 
From: Suganath prabu Subramani 

Never block the SEP device (i.e. Never invoke the
scsi_internal_device_block() API for SEP device) even for the delay not
responding events. Blocking the SEP device will create a deadlock while
adding any device to the OS.

[mpt3sas driver 06/10] mpt3sas: Added smp_affinity_enable module parameter.

2016-01-27 Thread Suganath prabu Subaramani 
From: Suganath prabu Subramani 

Module parameter to enable/disable configuring
affinity hint for msix vector.
SMP affinity feature can be enabled/disabled by setting
module parameter "smp_affinity_enable" to 1/0.
By default this feature is enabled. (smp_affinity_enable = 1 enabled).

[mpt3sas driver 07/10] mpt3sas: Add support for configurable Chain Frame Size

2016-01-27 Thread Suganath prabu Subaramani 
From: Suganath prabu Subramani 

Added support for configurable Chain Frame Size. Calculate the

[mpt3sas driver 09/10] mpt3sas: Fix for Asynchronous completion of timedout IO and task abort of timedout IO.

2016-01-27 Thread Suganath prabu Subaramani 
From: Suganath prabu Subramani 

Track msix of each IO and use the same msix for issuing
abort to timed out IO. With this driver will process IO's
reply first followed by TM.

[mpt3sas driver 05/10] mpt3sas: Make use of additional HighPriority credit message frames for sending SCSI IO's

2016-01-27 Thread Suganath prabu Subaramani 
From: Suganath prabu Subramani 

Driver assumes HighPriority credit as part of Global credit. But,
Firmware treats HighPriority credit value and global cedits as two
different values. Changed host queue algorithm to treat global credits and
highPriority credits as two different values.

From: Suganath prabu Subramani 

1.Wrong size of argument is being passed
 The size of struct being passed as an argument to memset func and area of
 memory being pointed by an instance of struct in memset func should be of
 same structure type.
2.Dereference null return value
3.Array compared against '0'
 Check whether value pointed by particular index of an array is null or not
 in "if" statement.

[mpt3sas driver patches 00/10] mpt3sas driver enhancements and

2016-01-27 Thread Suganath prabu Subaramani 
From: Suganath prabu Subramani 

Here is the change list:
Posting 10 patches for mpt3sas driver enhancements and few fixes.
  * Updated hardware description headers with MPI v2.6 and
mpt3sas_pci_table[] with vendor_ids,device_ids of Cutlass and
Intruder HBA which has support for 4 ports.
  * Static analyzer(coverity) tool identified defects.
  * Never block the SEP device even for the delay not
responding events. Blocking the SEP device will create a deadlock while
adding any device to the OS.
  * Modified host queue algorithm to treat global credits and
highPriority credits as two different values.
  * Module parameter to enable/disable configuring
affinity hint for msix vector.
  * Added support for configurable Chain Frame Size for
SAS 3.0 HBA'S.
  * Updated MPI version and MPI header files.
  * Fix for Asynchronous completion of timedout IO and task abort
of timedout IO.
  * Updated driver version to 12.100.00.00

Suganath prabu Subramani (10):
  mpt3sas: Added support for high port count HBA variants.
  mpt3sas: Used IEEE SGL instead of MPI SGL while framing a SMP
Passthrough request message.
  mpt3sas: Fix static analyzer(coverity) tool identified defects
  mpt3sas: Never block the Enclosure device
