2021-04-06session: basic support for interrupt modeFlorin Coras1-4/+26
Experimental support for session layer interrupt mode. When enabled (use-private-rx-mqs must be set) session queue node switches to interrupt state when lightly loaded, i.e., no events and less than 1 vector/dispatch. Because transport protocols require a periodic time update, when in interrupt state the session queue node workers register a timerfd with the unix-epoll-input node that when triggered signals, i.e., wakes up, the queue node. Under light load, the timer is set to trigger every 1ms whereas if no session is allocated, the worker moves to idle state and the timeout is set to 100ms.

2021-03-30session: interrupt mode for session node on main threadFlorin Coras1-15/+20

2021-03-29svm session vcl: per app rx message queuesFlorin Coras1-0/+6
Add option to use per app private segments for app to vpp message queues, as opposed to exposing internal message queues segment. When so configured, internal message queues are still polled by the session queue node but external app message queues are handled by a new input node (appsl-rx-mqs-input) that runs in interrupt state. Signaling of the node, when mqs receive new messages, is done through eventfds epolled by worker epoll input nodes.
