+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.
+
+Revision History:
+
+ 001 SEF 8/12/03 Initial release.
+ 002 SEF 8/20/03 Cleanup to match documentation.
+ 003 SEF 9/12/03 Additional cleanup, created combined header
+ 004 SEF 9/23/03 Changed base types to match linux defaults
+ Added RAID signature
+ Added bControllerFlags to CSMI_SAS_CNTLR_CONFIG
+ Changed CSMI_SAS_BEGIN_PACK to 8 for common structures
+ Fixed other typos identified in first compilation test
+ 005 SEF 10/03/03 Additions to match first version of CSMI document
+ 006 SEF 10/14/03 Fixed typedef struct _CSMI_SAS_SMP_PASSTHRU_BUFFER
+ Added defines for bConnectionRate
+ 007 SEF 10/15/03 Added Firmware Download Control Code and support
+ Added CSMI revision support
+ 008 SEF 10/30/03 No functional change, just updated version to track
+ spec changes
+ 009 SEF 12/09/03 No functional change, just updated version to track
+ spec changes
+ 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
+ 011 SEF 4/02/04 No functional change, added comment line before
+ 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.
