Just to state an obvious fact (not sure how that impacts your analysis though): There are, of course, many dependencies among device attach routines since your total time for the attach routine for a bus is going to include all of the time it takes for attach to run on all of the child devices. That is, pci0's attach time includes the attach time of all of it's descendant devices, and a given leaf node's attach time will be accounted for in the attach time of all of its parent nodes up to the root. For example: nexus0 acpi0 pcib0 pci0 ehci0 usbus0 uhub0 uhub3 uhub4 ukbd0 In this portion of my desktop's device tree, all of the devices listed will include the time of ukbd0's attach in their respective attach times. -- John Baldwin _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-security To unsubscribe, send any mail to "[email protected]"
