2020-05-20vcl: nest vcl_mq_epfd to support epoll_wait without high CPU usagehanlin1-0/+1
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.

2019-01-29vls: multi-process and multi-threaded apps improvementsFlorin Coras1-0/+2
- 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>
2019-01-07vcl/ldp: add locked sessions shim layerFlorin Coras1-0/+60
Moves LDP logic that allows sharing of sessions between multi-process app workers into a separate VCL shim layer. Also refactors LDP to use the new layer. Change-Id: I8198b51eae7d099a8c486e36b29e3a0cb8cee8e9 Signed-off-by: Florin Coras <fcoras@cisco.com>
