Oxidizing bmap-tools: rewriting a Python project in Rust

Back in September, I joined Collabora as an intern to work on Rust-related projects for six months. It's been a great experience and I would recommend it to anyone who is passionate about FOSS and wants to work in an inclusive environment with very skilled and supporting people! Over the internship, my goal was to continue to "oxidise" bmaptool, a tool for creating the block map (bmap) for a file

A brave new world: building glibc with LLVM

Times are changing: LLVM has become more than a spare to GCC, such that glibc - the last big GCC bastion, is now working towards supporting LLVM as a first-class citizen. This post is a sequel to last year's A tale of two toolchains and glibc. Unfamiliar readers are recommended to read the previous post for a better understanding of the progress being discussed here. It has been more than a year,

Landing a new syscall: What is futex?

Over the past 18 months, we have been on a roller-coaster ride developing futex2, a new set of system calls. As part of this prolonged effort, the futex_waitv() syscall has now successfully landed in Linux 5.16. A followup of the initial futex syscall, this new interface aims to overcome long term issues that have been limiting the way applications use the Linux kernel. But what exactly is futex?

Writing an open source GPU driver - without the hardware

After six months of reverse-engineering, the new Arm “Valhall” GPUs (Mali-G57, Mali-G78) are getting free and open source Panfrost drivers. With a new compiler, driver patches, and some kernel hacking, these new GPUs are almost ready for upstream. In 2021, there were no Valhall devices running mainline Linux. While a lack of devices poses an obvious obstacle to device driver development, there is
