2020-05-20vcl: nest vcl_mq_epfd to support epoll_wait without high CPU usagehanlin3-2/+125
Now, libc epfd and vls epfd are independent and can only epoll_wait independently without timeout, then app calling epoll_wait will occupy high CPU. So we nest vcl_mq_epfd into libc epfd when using eventfd with VPP, and then we can only epoll_wait libc epfd with specified timeout.

2020-05-14vcl svm: fix rx event losshanlin1-2/+5
When vcl_epoll_wait_handle_mq handles rx events exceeding maxevents, VPP will not signal because cursize > 0, and the remaining rx events cannot be triggered because the eventfd event has been read. Therefore, we should dequeue all events until cursize = 0. And then handle msg up to maxevents with vcl_epoll_wait_handle_mq_event and those beyond with vcl_handle_mq_event.

2020-05-04vcl: allow vcl worker index to be set by applicationsPivo2-0/+11
When using vppcom_session* apis to setup TCP sessions in applications build outside of the VPP repository, it is necessary to set the worker_index explicitly when these apis are called from the none-VCL worker threads. An example is when data is to be sent to the TCP session that is originated from a different thread, like the main program thread or from the bin api thread. This change allows the application to set it. Type: fix Signed-off-by: IJsbrand Wijnands <ice@cisco.com> Change-Id: I37f3654a49ea9a8cf3a0d3d0e672583018c12299

2020-02-25svm: refactor fifoFlorin Coras1-2/+4
Type: refactor Switch from a wrapped byte space to a "continuous" one wherein fifo chunks are appended to the fifo as more data is enqueued and chunks are removed as data is dequeued. The fifo is still subject to a maximum size, i.e., maximum number of bytes that can be enqueued, so the max number of chunks associated to the fifo is also constrained. When enqueueing data, which must fit within the available free space, if not enough "supporting" chunk memory is available, the fifo asks the fifo segment for enough chunk memory to ensure that the write can succeed. To avoid allocating large amounts of small chunks due to small writes, if possible, the size of the chunks requested is lower capped by min_alloc. When dequeuing data, all the chunks that have been completely drained, i.e., head moved beyond the chunks’ end bytes, are unlinked from the fifo and returned to the fifo segment. The one exception to this is the last chunk which is never unlinked. Change-Id: I98c1dbd9135fb79650365c7e40c29238b96cd4ee Signed-off-by: Florin Coras <fcoras@cisco.com>
