[dpdk-dev] [PATCH v3 46/68] vfio: allow to map other memory regions

2018-04-03 Thread Anatoly Burakov
Currently it is not possible to use memory that is not owned by DPDK to perform DMA. This scenarion might be used in vhost applications (like SPDK) where guest send its own memory table. To fill this gap provide API to allow registering arbitrary address in VFIO container. Signed-off-by: Pawel Wod
