2023-09-04session: fix allocation of proxy fifosFlorin Coras1-0/+1
Fifos need to be synchronously allocated once a transport like tcp accepts a session. Since events are now delivered asynchronously, proxy apps must explicitly register a cb function that manages fifo allocation prior to being notified of connect event. Type: fix Fixes: 0242d30 Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I7df973b7014e53e0766ea2bdc61e9871160bc18b
2023-08-09session: async rx event notificationsFlorin Coras1-12/+28
Move from synchronous flushing of io and ctrl events from transports to applications to an async model via a new session_input input node that runs in interrupt mode. Events are coalesced per application worker. On the one hand, this helps by minimizing message queue locking churn. And on the other, it opens the possibility for further optimizations of event message generation, obviates need for rx rescheduling rpcs and is a first step towards a fully async data/io rx path.

2020-02-25svm: refactor fifoFlorin Coras1-1/+5
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>
