Module Name:

   CSMISAS.H


Abstract:

   This file contains constants and data structure definitions used by drivers
   that support the Common Storage Management Interface specification for
   SAS or SATA in either the Windows or Linux.

   This should be considered as a reference implementation only.  Changes may
   be necessary to accommodate a specific build environment or target OS.

   010  SEF   3/11/04  Fixed typedef struct CSMI_SAS_RAID_DRIVES to include the
                       bFirmware member that is defined in the spec, but
                       was missing in this file,
                       added CC_CSMI_SAS_TASK_MANAGEMENT

   012  SEF   4/16/04  Added IOControllerNumber to linux header,
                       Modified linux control codes to have upper word of
                       0xCC77.... to indicate CSMI version 77
                       Added bSignalClass to CC_CSMI_SET_PHY_INFO
                       Added CC_CSMI_SAS_PHY_CONTROL support
   013  SEF   5/14/04  Added CC_CSMI_SAS_GET_CONNECTOR_INFO support
   014  SEF   5/24/04  No functional change, just updated version to track spec
                       changes
   015  SEF   6/16/04  changed bPinout to uPinout to reflect proper size,
                       changed width of bLocation defines to reflect size
   016  SEF   6/17/04  changed bLengthOfControls in CSMI_SAS_PHY_CONTROL
                       to be proper size
   017  SEF   9/17/04  added CSMI_SAS_SATA_PORT_SELECTOR,
                       CSMI_SAS_LINK_VIRTUAL, CSMI_SAS_CON_NOT_PRESENT, and
                       CSMI_SAS_CON_NOT_CONNECTED
   018  SEF   9/20/04  added CSMI_SAS_PHY_USER_PATTERN,
                       changed definition of CSMI_SAS_PHY_FIXED_PATTERN to not
                       conflict with activate definition
   019  SEF  12/06/04  added CSMI_SAS_GET_LOCATION
                       added bSSPStatus to CSMI_SAS_SSP_PASSTHRU_STATUS
                       structure
   020  SEF   5/25/05  added CSMI_SAS_PHY_VIRTUAL_SMP, and changes to
                       CSMI_SAS_GET_LOCATION
   021  SEF  11/03/05  added new RAID creation functionality
   022  SEF   2/01/06  corrected typo bNegotitiatedLInkRate
                       Added two more RAID_TYPES, 7 and 8
   023  SEF   4/04/06  added CSMI_RAID_TYPE_1E
                       changed structures that contained surface scan
                       to priority approach rather than time, causes
                       0.89 to incompatible with 0.87, so a version
                       check is necessary when interpreting the
                       raid structures
                       Added netware section
   024 DRG    5/22/06  Added uFailureCode to CSMI_SAS_RAID_CONFIG and
                       CSMI_SAS_RAID_FEATURES
                       Changed __u64 fields to high and low __u32 fields in
                       order to avoid backward compatibility issues with
                       packing and alignment.
                       Fixed alignment problem in CSMI_SAS_RAID_DRIVES.
                       Added CSMI_SAS_CNTLR_SMART_ARRAY to uControllerFlags
                       Reassigned the value of CSMI_SAS_CNTLR_RAID_CFG_SUPPORT
                       to avoid a conflict.
