Coroutine made DPDK dev easy
So, we try to use Photon coroutine lib to simplify the development of DPDK applications with the new concurrency model, and provide more functionalities, such as lock, timer and file I/O. First of all, we need to choose a userspace network protocol stack. After investigation, we have chosen Tencent's open source F-Stack project, which has ported the entire FreeBSD 11.0 network protocol stack on top of DPDK. It also has made some code cuts, providing a set of POSIX APIs, such as socket, epoll, kqueue, etc. Of course, its epoll is also simulated by kqueue, since it is essentially FreeBSD.

Finally, the PhotonLibOS project is open sourced at https://github.com/alibaba/PhotonLibOS. If you are interested in C++ coroutines and high-performance IO, welcome to have a try.

I was thinking of submitting a proposal to make std::coroutine_handle<void> convertible to void (*)() and was looking for feedback.

Recently programming languages rust swift kotlin are all have too many tricks, make chinese developers feel uncomfortable and naive .
I find a great project that can make any program support billions of concurrency: https://github.com/yyzybb537/libgo Of course it is created by a Chinese developer.
