io_uring - Wikipedia
io_uring[a] (previously known as aioring) is a Linux kernel system call interface for storage device asynchronous I/O operations addressing performance issues with similar interfaces provided by functions like read() / write() or aio_read() / aio_write() etc. for operations on data accessed by file descriptors.

干翻 nio ,王炸 io_uring 来了 !!(图解+史上最全) - 疯狂创客 …
2023年2月23日 · 在取名字上面,可以叫做 io_ring,ring_io更合适。u 是user的意思,ring是环形的意思。 一看到这里的ring,很容易知道,这里用了 环形队列。 环形队列是一个高性能的基础结构,大家去看 队列之王Disruptor、缓存之王 Caffeine ,里边用的就是环形队列。
Why you should use io_uring for network I/O | Red Hat Developer
2023年4月12日 · io_uring is an async interface to the Linux kernel that can potentially benefit networking. It has been a big win for file I/O (input/output), but might offer only modest gains for network I/O, which already has non-blocking APIs. The gains are likely to come from the following:
关于 io_uring 与 Rust 的思考 - 知乎 - 知乎专栏
本文将探讨在 Rust 中安全封装 io_uring 的一系列设计问题,并提出一些可能的解决方案。 io_uring 分为两个队列,提交队列 SQ (Submission Queue) 和完成队列 CQ (Completion Queue)。 提交队列存放正在等待执行的异步任务,完成队列存放完成事件。 io_uring 的结构由内核分配,用户态通过 mmap 拿到相关结构的内存访问权限,这样就能让内核态与用户态共享内存,绕过系统调用双向传递数据。 概念工作流程具有三个阶段. 准备:应用程序获取一些提交队列项 SQE …

聊聊 Libuv 最近引入的 io_uring - 知乎 - 知乎专栏
2023年10月19日 · io_uring 是 Linux 下高性能的异步 IO 框架,网上很多相关资料,我之前也初步分析了一下它的实现,有兴趣的可以查看 zhuanlan.zhihu.com/p/38。 Libuv 中最近加入了对 io_uring 的支持,那么为什么要把它引入 Libuv 呢? 因为 epoll 不支持普通文件的 Poll 能力,所以在 Libuv 中,异步文件 IO 操作需要通过 线程池 来实现,具体来说就是当用户发起一个异步文件 IO 操作时,Libuv 会把这个操作放到线程池中,当子线程处理这个任务时,会执行一个阻塞式的 …

digital-fabric/iou: Ruby gem for working with io_uring - GitHub
IOU provides a simple and idiomatic API for working with io_uring. IOU does not make any assumptions about the concurrency model in your application. It can be used in multi-threaded, multi-fibered, or callback-based apps. It largely follows the liburing API, but provides certain Ruby-esque amenities to make it easier to use io_uring in Ruby apps.
