Hi, ATA ODD has a new feature called device attention, which means it can notify sata host that it needs power when in powered off state. In libata, we can set a flag(ATA_DFLAG_DA) to represent this when identifying the ata device. And when we are going to create the scsi device(in ata_scsi_scan_host by __scsi_add_device), I hope the scsi driver(sr) knows that this ODD supports device attention in its probe function(sr_probe). I didn't find a proper way to do this, any suggestions? Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
