Writing Device Drivers

driver.conf Files

driver.conf files are required for devices that are not self-identifying. Entries in the driver.conf file specify possible device instances the driver will probe for existence. For more information, see the scsi(4) and driver.conf(4) man pages. Driver global properties can also be set by entries in the driver.conf file. driver.conf files are optional for self-identifying devices (SID), where the entries can be used to add properties into SID nodes. See the sbus(4) and pci(4) man pages for details.
