io_uring / IoRing loop

[staabm]

Would it make sense to implement a new based on io_uring / IoRing?

Found a discussion which shares other languages/applications to use a io_uring based loop for better performance, see https://news.ycombinator.com/item?id=23133040

IoRing on Windows: oven-sh/bun#43 (comment)

the origin idea for opening this issue is by Arnauld, a php-src developer

In short, if there is a way to access it from PHP through core functions or extensions, then yes it would make sense if we can get all supported features we expect from event loops in.

This would be nice to have, but not at the top of my TODO list. Also keep in mind that uring is still quite young and people keep finding new vulnerabilities, so Google disabled it on their production servers.

For what it's worth: (limited) support for io_uring was added in libuv a while ago: libuv/libuv#1947.

Yep, the uv backend already automatically uses io_uring when possible (causing permanent kernel memory leaks on specific Linux versions unless disabled via UV_USE_IO_URING :)))
