XPT(4) Kernel Interfaces Manual XPT(4) NAME xpt -- CAM transport layer interface SYNOPSIS None. DESCRIPTION The xpt driver provides a way for userland applications to issue certain CAM CCBs to the kernel. Since the xpt driver allows direct access to the CAM subsystem, system ad- ministrators should exercise caution when granting access to this driver. If used improperly, this driver can allow userland applications to crash a machine or cause data loss. KERNEL CONFIGURATION There is no kernel configuration required for the xpt driver. It is en- abled when SCSI support is enabled in the kernel. There is one instance of the xpt driver per CAM transport layer instance. Since there is currently only one CAM transport layer, there will only be one instance of this dri- ver. IOCTLS CAMIOCOMMAND CAMGETPASSTHRU FILES /dev/xpt0 Character device node for the xpt driver. DIAGNOSTICS None. SEE ALSO cam(3), cam_cdbparse(3), pass(4), camcontrol(8) HISTORY The CAM transport layer driver first appeared in FreeBSD 3.0. AUTHORS Kenneth Merry <ken@FreeBSD.org> FreeBSD ports 15.1 October 10, 1998 XPT(4)
