2019-01-29vls: multi-process and multi-threaded apps improvementsFlorin Coras1-1/+1
- More fine tuning for multi-process applications. - Experimental support for multi-thread apps. This is meant for app whose threads are not vcl workers and the sessions are shared between them. Change-Id: Ie07651da5f2cdcf39f5dead5431f50ad39cf3f74 Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-08-10vcl: support for eventfd mq signalingFlorin Coras4-27/+167
- support eventfd based mq signaling. Based on configuration, vcl epoll/select can use either condvars or epoll on mq eventfds. - add vcl support for memfd segments - vpp explicitly registers cut-through segments with apps/vcl - if using eventfd, make ldp allow one call to libc_epoll_create. Needed for the message queue epfd - update svm_queue_t to allow blocking calls with eventfd signaling.

2018-07-27vcl: use events for epoll/select/read/writeFlorin Coras3-18/+44
Have vcl poll and wait on the event message queues as opposed to constantly polling the session fifos. This also adds event signaling to cut through sessions. On the downside, because we can't wait on multiple condvars, i.e., when we have multiple message queues because of cut-through registrations, we do timed waits.

2018-06-05VPP API: Memory traceOle Troan1-0/+4

If the caller is the session owning thread or the main thread with a worker barrier sync (cli/api) add an event to the pending disconnects vector in the session node and entirely avoid using the event queue. Useful for bursts of disconnects (like an app detach). If disconnects come from a processes, be willing to retry enqueueing the disconnect to the event queue multiple times.
