In previous DPDK version, we implement a user space character device driver vhost-cuse in user space DPDK process. vring information is passed to the cuse driver through ioctl call, including eventfds for interrupt injection and host notification. A kernel module is developed to copy these fds from qemu process into our process. We also need some trick to map guest memory. (TODO: kickfd/callfd is reversed which causes confusion) known issue in vhost-user implementation in QEMU, reported by haifeng.lin@huawei.com * QEMU doesn't send correct memory region information with multiple numa node configuration http://lists.gnu.org/archive/html/qemu-devel/2014-12/msg01454.html Thanks Tetsuya for reporting the issue that "FD_ISSET would crash when receive -1 as fd on Ubuntu 14.04". Huawei Xie (11): enable VIRTIO_NET_F_CTRL_RX create vhost_cuse directory and move vhost-net-cdev.c into vhost_cuse rename vhost-net-cdev.h to vhost-net.h move fd copying(from qemu process into vhost process) to eventfd_copy.c copy host_memory_map from virtio-net.c to a new file virtio-net-cdev.c make host_memory_map a more generic function. implement cuse_set_memory_table in virtio-net-cdev.c add select based event driven processing vhost user support support dev->ifname support calling rte_vhost_driver_register after rte_vhost_driver_session_start lib/librte_vhost/Makefile | 8 +- lib/librte_vhost/rte_virtio_net.h | 5 +- lib/librte_vhost/vhost-net-cdev.c | 389 -------------------- lib/librte_vhost/vhost-net-cdev.h | 113 ------ lib/librte_vhost/vhost-net.h | 118 +++++++ lib/librte_vhost/vhost_cuse/eventfd_copy.c | 88 +++++ lib/librte_vhost/vhost_cuse/eventfd_copy.h | 39 ++ lib/librte_vhost/vhost_cuse/vhost-net-cdev.c | 417 ++++++++++++++++++++++ lib/librte_vhost/vhost_cuse/virtio-net-cdev.c | 423 ++++++++++++++++++++++ lib/librte_vhost/vhost_cuse/virtio-net-cdev.h | 48 +++ lib/librte_vhost/vhost_rxtx.c | 2 +- lib/librte_vhost/vhost_user/fd_man.c | 258 ++++++++++++++ lib/librte_vhost/vhost_user/fd_man.h | 67 ++++ lib/librte_vhost/vhost_user/vhost-net-user.c | 472 +++++++++++++++++++++++++ lib/librte_vhost/vhost_user/vhost-net-user.h | 106 ++++++ lib/librte_vhost/vhost_user/virtio-net-user.c | 314 ++++++++++++++++ lib/librte_vhost/vhost_user/virtio-net-user.h | 49 +++ lib/librte_vhost/virtio-net.c | 491 ++------------------------ lib/librte_vhost/virtio-net.h | 43 +++ 19 files changed, 2491 insertions(+), 959 deletions(-) delete mode 100644 lib/librte_vhost/vhost-net-cdev.c delete mode 100644 lib/librte_vhost/vhost-net-cdev.h create mode 100644 lib/librte_vhost/vhost-net.h create mode 100644 lib/librte_vhost/vhost_cuse/eventfd_copy.c create mode 100644 lib/librte_vhost/vhost_cuse/eventfd_copy.h create mode 100644 lib/librte_vhost/vhost_cuse/vhost-net-cdev.c create mode 100644 lib/librte_vhost/vhost_cuse/virtio-net-cdev.c create mode 100644 lib/librte_vhost/vhost_cuse/virtio-net-cdev.h create mode 100644 lib/librte_vhost/vhost_user/fd_man.c create mode 100644 lib/librte_vhost/vhost_user/fd_man.h create mode 100644 lib/librte_vhost/vhost_user/vhost-net-user.c create mode 100644 lib/librte_vhost/vhost_user/vhost-net-user.h create mode 100644 lib/librte_vhost/vhost_user/virtio-net-user.c create mode 100644 lib/librte_vhost/vhost_user/virtio-net-user.h create mode 100644 lib/librte_vhost/virtio-net.h -- 1.8.1.4
