> Is it more efficient resource and time-wise to rewrite everything in [Language of choice], or to comb through the currently existing code manually and with special tools to find bugs and fix them? This is for the NVK project, which is creating an open source GPU driver for NVIDIA GPUs. The project has a number of considerations that are not in the blog post: > The unfortunate reality is that, while the original nouveau drivers were written by some amazing engineers and were state-of-the-art a decade ago, they have fallen behind in the last several years. The few developer hours it gets are mostly spent on basic hardware enablement and trying to get new OpenGL versions, leaving the systemic and architectural issues unaddressed. You can find more complete rationale in their announcement blog post, and it seems very thoughtful: https://www.collabora.com/news-and-blog/news-and-events/introducing-nvk.html https://www.collabora.com/news-and-blog/news-and-events/intr... If you want Yet Another Example of using Rust to write GPU drivers, you can look at the other Mesa driver in development (for the Apple AGX GPUs): https://asahilinux.org/2022/11/tales-of-the-m1-gpu/ https://asahilinux.org/2022/11/tales-of-the-m1-gpu/ (see "Rust is magical!")
