2016-02-25Add live migration support to (non-dpdk) vhost-user driverYoann Desmouceaux2-8/+144
This patch adds live migration support to vhost interfaces, by supporting the VHOST_F_LOG_ALL feature. When qemu starts a migration, it will negotiate this feature, and provide a fd for a "dirty log" shared mem space. This log is a bitmap representing pages in the device memory. Whenever we touch memory pointed by a "desc" vring, or modify a "used" vring, we log the corresponding page in the bitmap. This allows qemu to send the dirty page to the destination host. See https://github.com/qemu/qemu/blob/master/docs/specs/vhost-user.txt, ยง "Live migration" for more details. In addition to this, this code provides support for the VHOST_USER_F_PROTOCOL_FEATURES feature, and to VHOST_USER_{GET,SET}_PROTOCOL_FEATURES and VHOST_USER_SET_VRING_ENABLE messages, required for live migration.

2016-02-24Handle dynamic enable/disable VHOST_USER interfaceShesha Sreenivasamurthy4-11/+29
If number of Qs enabled by the guest is less than number of Qs exported to guest, then all threads route packet to Q0 with the assumption that guest is not interested in performance. If all Qs are enabled, each thread queues packet in their own TX-Q of the VHOST_USER interface, boosting performance.

Adding a patch to fix DPDK 2.2.0 enic PMD driver TX function. The enic PMD driver send function uses a constant offset instead of relying on the data_off in the mbuf to find the start of the packet.

2016-02-19Rebalance checkConnected()Robert Varga1-8/+9
AtomicBoolean forces the enclosed boolean to be cache-aligned, needlessly hitting a cacheline. Since we only flip state only once, when the connection is severed, we can turn this into a volatile boolean. Doing that is costing us a synchronized close(), but that is perfectly acceptable, as that is called only once.

2016-02-18Add jumbo frames support to non-dpdk vhost interfaces.Pierre Pfister4-290/+394
This code provided inter-VM (2 cores per VM) throughput of 22Gbps using iperf through VPP (1 core) with 9k frames. With the same setup and pktgen running on both sides, it reached 5Mpps with no packets drop (Equivalent to before the patch). During the tests the average vector length was about 1, which likely means that VPP is not the bottleneck. The patch also includes some generic functions for vlib buffers allowing for chained buffer construction whether or not DPDK is enabled.
