SCSI Functions

The SCSI functions are:

scsi_probe(): Probe a SCSI device
scsi_unprobe(): Free resources allocated during initial probing
scsi_alloc_consistent_buf(): Allocate an I/O buffer for SCSI DMA
scsi_free_consistent_buf(): Free a previously allocated SCSI DMA I/O buffer
scsi_init_pkt(): Prepare a complete SCSI packet
scsi_destroy_pkt(): Free an allocated SCSI packet and its DMA resource
scsi_setup_cdb(): Set up SCSI command descriptor block (CDB)
scsi_transport(): Start a SCSI command
scsi_poll(): Run a polled SCSI command
scsi_ifgetcap(): Get SCSI transport capability
scsi_ifsetcap(): Set SCSI transport capability
scsi_sync_pkt(): Synchronize CPU and I/O views of memory
scsi_abort(): Abort a SCSI command
scsi_reset(): Reset a SCSI bus or target
scsi_reset_notify(): Notify the target driver of bus resets
scsi_cname(): Decode a SCSI command
scsi_dname(): Decode a SCSI peripheral device type
scsi_mname(): Decode a SCSI message
scsi_rname(): Decode a SCSI packet completion reason
scsi_sname(): Decode a SCSI sense key
scsi_errmsg(): Display a SCSI request sense message
scsi_log(): Display a SCSI-device-related message
scsi_vu_errmsg(): Display a SCSI request sense message
scsi_hba_init(): SCSI HBA system initialization routine
scsi_hba_fini(): SCSI HBA system completion routine
scsi_hba_attach_setup(): SCSI HBA attach routine
scsi_hba_detach(): SCSI HBA detach routine
