Multi Queue Linux Block Device Drivers in Rust - Building Safe Kernel Drivers

Explore a 50-minute conference talk from the Storage Developer Conference (SDC) 2023 that delves into implementing Linux block device drivers using Rust programming language. Learn about the Rust for Linux project's progress in developing safe abstractions for kernel device drivers, with a specific focus on PCI NVMe driver implementation. Discover how the Rust null_blk Linux kernel driver addresses memory safety issues that account for 41% of bug fixes in the C implementation. Gain insights into achieving performance parity with C-based drivers, understanding the use of unsafe Rust in the Linux kernel, and writing safe device drivers for multi-queue storage devices. Presented by Andreas Hindborg from Samsung, the talk demonstrates the feasibility of Rust as an implementation language for high-performance device drivers while highlighting its advantages in preventing memory safety issues common in C kernel code.
