Hi, I am writing a small kernel module, which splits into 2 part: one runs in dom0, and the other runs in domU. The main job is to exchange some data between them, and there is no hardware related. It seems simple enough: dom0 module watches for domU via xenstore, then they exchange grant-table-ref with each other and then go ahead doing their work. The problem is: I saw all the xen drivers, and they all register to xenbus (with xenbus_driver structure). Look again at my code, I dont see why I need to exploit the xebus_driver interface. So my question is: Why I need xenbus_driver in my case, and what is the advantages? (That confuses me is looks like I can survive without it) Many thanks.
