Rust-Based OS "Redox OS" Advances Real Hardware Support—April 2026 Progress Report

Rust-Based OS “Redox OS” Steadily Advances Real Hardware Support

The open-source operating system “Redox OS,” developed entirely from scratch using the Rust programming language, has released its April 2026 progress report. Previously limited to running on virtual machines, the OS has made significant strides toward booting on real hardware, marking an important milestone in its development.

Focus on Improving Booting on Real Hardware

The highlight of this month’s updates is a series of improvements to enable Redox OS to boot on real hardware. Up until now, Redox OS was primarily tested and validated in virtual machine environments like QEMU. However, with fixes related to booting and support for the latest Rust-OSDev ACPI crate, the system has expanded compatibility to a broader range of hardware. Additionally, boot time on machines with multi-core CPUs has been significantly reduced.

Progress in RISC-V Support and tmux Porting

Advancements in compatibility with the RISC-V architecture were also reported. As an open instruction set architecture, RISC-V is gaining attention for its potential in embedded and edge devices, and this update lays the groundwork for future expansion in these areas. Furthermore, the terminal multiplexer “tmux” has been successfully ported to Redox OS. tmux, a familiar tool for Linux users, directly enhances developer productivity, making this a noteworthy update.

Performance Improvements in Orbital Desktop

The native desktop environment of Redox OS, “Orbital,” has seen performance improvements. By supporting partial pixel updates for windows, the rendering performance has been enhanced, resulting in smoother window movements and an improved user experience.

Kernel and Library Stability Enhancements

Inside the kernel, numerous reliability improvements have been implemented, including fixes for memory leaks, enhanced stability for multithreading, and the elimination of potential deadlocks. Additionally, the video driver has undergone changes, with the previous Bochs driver replaced by a VESA driver, reducing code redundancy.

Redox OS’s libc implementation, “Relibc,” has also been significantly improved. As an alternative to the standard C library, Relibc contributes to better POSIX compliance, further strengthening the OS’s foundation.

Conclusion: Transitioning from Experimental to Practical

This update demonstrates that Redox OS is evolving from being an “interesting experimental OS” to a practical operating system capable of running on real hardware. Leveraging Rust’s memory safety features, the OS shows great potential for growth, with expanding ecosystems and a growing community worth watching closely.

Frequently Asked Questions

Q: What is Redox OS?
A: Redox OS is an open-source operating system developed from scratch using the Rust programming language. It adopts a Unix-like design and uses its own implementation of the standard C library, Relibc. The OS also features a unique graphical interface, including its desktop environment, Orbital.

Q: What are the advantages of being written in Rust?
A: Rust’s ownership model and type safety prevent memory-related bugs, such as buffer overflows and use-after-free errors, at compile time. This makes it particularly suitable for kernel and low-level code, reducing vulnerabilities compared to languages like C.

Q: How advanced is real hardware support?
A: The latest update has improved ACPI support and reduced boot times on multi-core CPUs, expanding the environment where Redox OS can run on real hardware. However, it does not yet support all hardware comprehensively, and development is still ongoing, particularly for graphics and network drivers. Support for RISC-V boards is also progressing.
