Revamping ioctl with io_uring - Enhancing Kernel-User Communication

Explore the innovative io_uring command facility, a modern equivalent of asynchronous ioctl, in this conference talk from the Linux Foundation. Delve into the API and design of io_uring command, which addresses the efficiency gaps in traditional ioctl communication between user-space and kernel. Learn how Linux developers can leverage this infrastructure to attach various io_uring capabilities to arbitrary commands. Discover practical examples of using this interface on fast storage devices like NVMe SSDs, and gain insights into utilizing the efficiency knobs of io_uring. By the end of this 46-minute presentation, acquire a comprehensive understanding of io_uring and how to construct efficient pathways between kernel and user space for high-performance asynchronous software development.
