- make SATA SIMs announce capabilities to handle SDB with Notification bit; - make PMP driver honor this SIMs capability; - make SATA XPT to negotiate and enable this feature for ATAPI devices. This feature allows supporting SATA ATAPI devices to inform system about some events happened, that may require attention. In my case this allows LG GH22LS50 SATA DVR-RW drive to report tray open/close events. Events reported to CAM in form of AC_SCSI_AEN async. Further they could be used as a hints for checking device status and reporting media change to upper layers, for example, via spoiling mechanism of GEOM. |
