Through vfio-user client interface, PCI liked device could be used similar as Intel® Ethernet Adaptive Virtual Function specification. The code to enable iavf_client mainly contains two parts: - Emulated pci interfaces for vfio-user client which is located in common/iavf/vfio_user/. - A new net driver base on vdev abstraction, i.e. iavf_client_ethdev.c ---------------------- | ------------------ | | | iavf driver | |----> (iavf_client_ethdev.c) | ------------------ | | ------------------ | | | device emulate | |------>(common/iavf/vfio_user/) | ------------------ | ---------------------- | | ---------------------- | vfio-user | | client | ---------------------- This driver can be used to test the device emulation framework mentioned in: [RFC 0/2] Add device emulation support in DPDK http://patchwork.dpdk.org/cover/75549/ +------------------------------------------------------+ | +---------------+ +---------------+ | | | iavf_emudev | | iavfbe_ethdev | | | | driver | | driver | | | +---------------+ +---------------+ | | | | | | ------------------------------------------- VDEV BUS | | | | | | +---------------+ +--------------+ | +--------------+ | | vdev: | | vdev: | | | +----------+ | | | /path/to/vfio | |iavf_emudev_# | | | | iavf | | | +---------------+ +--------------+ | | | client | | | | | +----------+ | | | | | +----------+ | | +----------+ | | | vfio-user| | | | vfio-user| | | | client | |<---|----->| server | | | +----------+ | | +----------+ | | QEMU/DPDK | | DPDK | +--------------+ +------------------------------------------------------+ It can be launched together with patch series for the testing: [0/9] Introduce vfio-user library: http://patchwork.dpdk.org/cover/85389/ [0/8]Introduce emudev library and iavf emudev driver http://patchwork.dpdk.org/cover/85488/ This series depends on patch serieses: [0/9] Introduce vfio-user library: http://patchwork.dpdk.org/cover/85389/ Jingjing Wu (2): common/iavf: emulated pci interfaces on vfio-user client net/iavf: introduce iavf driver on vfio-user client config/rte_config.h | 3 + drivers/common/iavf/iavf_common.c | 7 + drivers/common/iavf/iavf_impl.c | 45 +- drivers/common/iavf/iavf_osdep.h | 14 + drivers/common/iavf/iavf_prototype.h | 1 + drivers/common/iavf/iavf_type.h | 3 + drivers/common/iavf/meson.build | 11 +- drivers/common/iavf/version.map | 5 + drivers/common/iavf/vfio_user/vfio_user_pci.c | 517 ++++++++++++++++++ drivers/common/iavf/vfio_user/vfio_user_pci.h | 66 +++ drivers/net/iavf/iavf.h | 18 +- drivers/net/iavf/iavf_client_ethdev.c | 298 ++++++++++ drivers/net/iavf/iavf_ethdev.c | 26 +- drivers/net/iavf/iavf_rxtx.c | 23 +- drivers/net/iavf/meson.build | 1 + 15 files changed, 1015 insertions(+), 23 deletions(-) create mode 100644 drivers/common/iavf/vfio_user/vfio_user_pci.c create mode 100644 drivers/common/iavf/vfio_user/vfio_user_pci.h create mode 100644 drivers/net/iavf/iavf_client_ethdev.c -- 2.21.1
