This PMD is implemented as thin wrapper of librte_vhost. * Known issue. We may see issues while handling RESET_OWNER message. These handlings are done in vhost library, so not a part of vhost PMD. So far, we are waiting for QEMU fixing. PATCH v4 changes: - Rebase on latest DPDK tree. - Fix cording style. - Fix code not to invoke multiple messaging handling threads. - Fix code to handle vdev parameters correctly. - Remove needless cast. - Remove needless if-condition before rt_free(). PATCH v3 changes: - Rebase on latest matser - Specify correct queue_id in RX/TX function. PATCH v2 changes: - Remove a below patch that fixes vhost library. The patch was applied as a separate patch. - vhost: fix crash with multiqueue enabled - Fix typos. (Thanks to Thomas, Monjalon) - Rebase on latest tree with above bernard's patches. PATCH v1 changes: - Support vhost multiple queues. - Rebase on "remove pci driver from vdevs". - Optimize RX/TX functions. - Fix resource leaks. - Fix compile issue. - Add patch to fix vhost library. RFC PATCH v3 changes: - Optimize performance. In RX/TX functions, change code to access only per core data. - Add below API to allow user to use vhost library APIs for a port managed by vhost PMD. There are a few limitations. See "rte_eth_vhost.h". - rte_eth_vhost_portid2vdev() To support this functionality, vhost library is also changed. Anyway, if users doesn't use vhost PMD, can fully use vhost library APIs. - Add code to support vhost multiple queues. Actually, multiple queues functionality is not enabled so far. RFC PATCH v2 changes: - Fix issues reported by checkpatch.pl (Thanks to Stephen Hemminger) Tetsuya Mukawa (2): vhost: Add callback and private data for vhost PMD vhost: Add VHOST PMD config/common_linuxapp | 6 + doc/guides/nics/index.rst | 1 + doc/guides/rel_notes/release_2_2.rst | 2 + drivers/net/Makefile | 4 + drivers/net/vhost/Makefile | 62 ++ drivers/net/vhost/rte_eth_vhost.c | 783 ++++++++++++++++++++++++++ drivers/net/vhost/rte_eth_vhost.h | 65 +++ drivers/net/vhost/rte_pmd_vhost_version.map | 8 + lib/librte_vhost/rte_vhost_version.map | 6 + lib/librte_vhost/rte_virtio_net.h | 3 + lib/librte_vhost/vhost_user/virtio-net-user.c | 13 +- lib/librte_vhost/virtio-net.c | 60 +- lib/librte_vhost/virtio-net.h | 4 +- mk/rte.app.mk | 8 +- 14 files changed, 1011 insertions(+), 14 deletions(-) create mode 100644 drivers/net/vhost/Makefile create mode 100644 drivers/net/vhost/rte_eth_vhost.c create mode 100644 drivers/net/vhost/rte_eth_vhost.h create mode 100644 drivers/net/vhost/rte_pmd_vhost_version.map -- 2.1.4
