The link dependency rule does nothing to cause the driver to attach, or stay attached. To address that concern, there are at least three different approaches: 1) use a layered driver open (see ldi_open_xxx) and keep D's /dev entry open from A while in use. 2) use a ddi-forceattach and ddi-no-autodetach properties in D's driver.conf file. 3) change the dependency of A to D to be expressed in terms of nexus/leaf driver (e.g. SCSI HBA and disk). This probably requires using private nexus driver interfaces, and may be more complicated than it is worth, especially if the relationship doesn't logically map to the child/parent paradigm. Either approach will work. _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
