WRITING A RUST GPU KERNEL DRIVER: A BRIEF INTRODUCTION ON HOW GPU DRIVERS WORK

Summary from the TLDR Web Dev newsletter

This article teaches the basics of GPU driver architecture, focusing on the user-mode driver (UMD) and kernel-mode driver (KMD) relationship using an example of rendering a rotating cube with Vulkan (VkCube). The UMD translates high-level API commands into lower-level GPU instructions, while the KMD manages memory allocation, job scheduling, and hardware initialization. The Tyr driver, a Rust-based KMD, provides an interface for device information, memory management, job submission, and tiler heap management.
