Hi, I am a jackaroo on Solaris. And the problem puzzles me. There is such a sentence in an article:"Those devices which have other devices attached to them (typically via a bus) use nexus drivers." Then, for the nexus drivers, how to search for its child devices?
In fact, I want to write a HBA driver(more exactly, it's a virtual HBA driver) now, but there are some problems: What are the differences between a 'leaf' driver and a 'nexus' driver? For a FC HBA drivers, how to scan its child devices(for example, some FC disks is under the FC HBA cards)? Is driver's bus_ops structure helpful? I heard that:"a nexus must enumerate its own children ", but how to do that? What should I do to help the 'nexus' to 'enumerate its own children'? Thank you!
