>
>Platform bus is a bus under Linux which manages devices that do not have any discovery-mechanism
>built in. Linux learns about platform devices directly from device-tree during boot-up phase.
>
>Afterwards if userspace wants to use some particular device driver being usually a mixture of
>vdev/rawdev gets developed.
>
>In order to simplify that introduce a DPDK platform bus which provides auto-probe experience and
>separates a bus logic from the driver itself.
>
>Now only devices which are backed-by vfio-platform kernel driver are supported, though other
>options may be added if necessary.
