Author: smh Date: Fri Apr 26 15:53:22 2013 New Revision: 249933 URL: http://svnweb.freebsd.org/changeset/base/249933 Log: Added the ability to send ATA identify and Data Set Management (DSM) TRIM commands to an ATA device attached via a SCSI control. sys/cam/scsi/scsi_all.c: - Added scsi_ata_identify, scsi_ata_trim Which use ATA Pass-Through to send commands to the attached disk. sys/cam/scsi/scsi_all.h: - Added defines for all missing ATA Pass-Through commands values. - Added scsi_ata_identify, scsi_ata_trim methods used in ATA TRIM support. - Added scsi_vpd_logical_block_prov structure used when querying for the supported sizes UNMAP commands. - Added scsi_vpd_block_limits structure used when querying for the supported sizes of the UNMAP command.
