The rationale has been partially explained in [2]. This first part covers the introduction of the necessary facilities in rte_bus to allow for generic device parsing. This API is implemented for the virtual and PCI buses. Additionally, this rte_bus evolution is being used within rte_devargs to characterize a device type by its bus. This work is the first of two parts to reduce the dependency of the EAL upon specific bus implementations. Two public functions are added to rte_bus to help bus recognition: - rte_bus_from_name - rte_bus_from_dev These functions are made public because the bus handle within devargs becomes the generic device type. Recognizing device types is useful for buses and PMDs alike. The modified rte_devargs parsing allows declaring on the EAL command line explicit buses to handle a device. The format is as follow: --vdev="virtual:net_ring0" --vdev="net_tap0,iface=tap0" -w PCI:00:02.0 -w 00:03.0 This explicit bus designation is optional; no evolution is currently forced on users to migrate to this new format. The separating character is arbitrary and can be any character illegal within a bus name. Subsequently, what is allowed within a bus name has been formally defined and is now enforced.
