[RFC 0/12] mpt2sas v00.100.11.15: 4th revision

[Eric Moore]

* This is new scsi lld device driver from LSI supporting the SAS 2.0 standard. I have split patchs by filename.
* Here is list of new 6gb host controllers:

  LSI SAS2004
  LSI SAS2008
  LSI SAS2108
  LSI SAS2116

* Here are the changes in the 4th posting of this patch set:

(1) fix compile errors when SCSI_MPT2SAS_LOGGING is not enabled
(2) add mpt2sas to the SCSI Mid Layer Makefile
(3) append mpt2sas_ to the naming of all non-static functions
(4) fix oops for SMP_PASSTHRU
(5) doorbell algorithm imported changes from windows driver

* Here are the changes in the 3rd posting of this patch set:

(1) add readl following writel from the function that disables interrupts
(2) replace 0xFFFFFFFFFFFFFFFFULL with ~0ULL
(3) when calling pci_enable_msix, only pass one msix entry (instead of 15).
(4) remove the "current HW implementation uses..... " comment in the sources
(5) merged bug fix for SIGIO/POLLIN notifcation; reported by the storlib team.

* Here are the changes in the 2nd posting of this patch set:

(1) use little endian types in the mpi headers
(2) merged in bug fix's from inhouse drivers.

* Here is a summary of the patchs:

[PATCH 1/12] mpt2sas_base - Common API layer interface to MPT (Message Passing Technology) firmware.
[PATCH 2/12] mpt2sas_config - Common API for accessing firmware configuration pages.
[PATCH 3/12] mptsas_ctl - Storage Management Module.
[PATCH 4/12] mpt2sas_scsih - SCSI Host Layer.
[PATCH 5/12] mpt2sas_transport - Common API for accessing the Kernel SAS Transport Layer.
[PATCH 6/12] mpt2sas_debug - Common Header for debug logging.
[PATCH 7/12] mpi headers  -  Common MPI (Message Passing Interface) Headers.
[PATCH 8/12] Kconfig: mpt2sas Kernel configuration file.
[PATCH 9/12] Makefile - mpt2sas driver Makefile.
[PATCH 10/12] scsiml Kconfig - Adding mptsas to the common scsi ml Kconfig.
[PATCH 11/11] linux/miscdevice.h - Adding suport for MPT2SAS_MINOR(221)
[PATCH 12/12] scsiml Makefile - add mpt2sas to the SCSI Mid Layer Makefile

Re: [RFC 0/12] mpt2sas v00.100.11.15: 4th revision

[peter Bogdanovic]

I confirmed the fix for the mpt2sas compilation errors when
SCSI_MPT2SAS_LOGGING wasn't set and the patch of the Med Layer Makefile.
The mpt2sas driver compiles now without error or warning with or without
logging enabled.

I have also had a chance to test the driver with a lsi sas 2108 card and
the ibm ds3200 sas enclosure. I see no errors on when I insert or remove
the driver. I ran block i/o tests for more that 24 hours using disktest
without error.
