This sounds good to me. As a basic software design rule, the decisions of using a given resource and/or performing a given operation (the intelligent knowledge) should systematically be taken at the maximum possible software level. Conversely, such high-level decisions should be offered the most appropriate low-level services to facilitate their implementation. In the case we are considering here - the need to bind a PCI device - the Poll Mode Driver of that device is the only component which actually knows. Conversely, the EAL layer is the best place where to implement the OS-dependent and/or architecture-dependent device binding services to be invoked by PMDs at PCI device probing time.
