GCC 15.1's Rust Front-End Gets Major Boost

2025-03-24

The upcoming GCC 15.1 release will feature significant improvements to its Rust front-end, gccrs. Arthur Cohen of Embecosm merged a third patch set adding support for Rust's "if let" statements, massive changes to internal AST/HIR representations, and full implementation of Clone and Copy. Further improvements, including support for PartialOrd and PartialEq, are expected before the release, making gccrs a more viable alternative to rustc.

Intel Drops 256-bit AVX-10 Mode, Goes All-in on 512-bit

2025-03-19

Intel has significantly revised its AVX-10 instruction set whitepaper, abandoning the previously planned optional 256-bit mode in favor of a full 512-bit vector width. This means future Intel E-core processors will fully support AVX-512, aligning with AMD's Zen 4 architecture. The change stems from updated GCC compiler patches removing 256-bit compatibility. This simplifies instruction set handling and boosts the competitiveness of future Intel Xeon E-core server platforms, better competing with AMD's EPYC processors. While a late decision, it positively impacts the future of the x86_64 microarchitecture.

GCC 15 to Support COBOL!

2025-03-11

A major update is coming to the GCC 15 compiler: COBOL language front-end support has been merged! This is a significant step forward for GCC's COBOL support, facilitating the migration of legacy mainframe COBOL applications to Linux and cloud environments. While COBOL's popularity isn't what it once was, this merge is still a welcome surprise. Developers can use the `gcobol` command to invoke the COBOL compiler front-end. Expect COBOL support alongside many other features in the GCC 15.1 stable release in the coming weeks.

Linux Kernel Embraces Rust: The End of C's Memory Safety Nightmares?

2025-02-20

Greg KH, a long-time Linux kernel maintainer, advocates for using Rust to rewrite parts of the kernel in an LKML post. He argues that a significant portion of kernel bugs stem from subtle flaws in C, which Rust's memory safety features would effectively prevent. While a complete migration to Rust is unrealistic, writing new code and drivers in Rust would dramatically reduce bugs and improve development efficiency. Greg urges kernel developers to embrace Rust for the long-term health of the Linux project.

Linux Kernel Rust Controversy: Maintainer Rejects Linus's Push

2025-02-18

Linux kernel maintainer Christoph Hellwig publicly opposes the forced adoption of Rust in the kernel. He points out that Linus Torvalds privately stated he would override maintainers' vetoes and merge Rust code anyway. Hellwig worries this will turn the kernel codebase into an unmaintainable multi-language mess, increasing maintenance burden and ultimately harming the kernel's long-term stability. He argues that addressing kernel memory safety issues should prioritize improving existing code, not introducing a new language, and calls for clear language usage guidelines.

Veteran Open-Source Driver Developer Resigns Over Inclusivity Concerns

2025-02-17

Longtime Nouveau driver developer Karol Herbst resigned as a maintainer of the open-source NVIDIA Linux graphics driver due to disagreements with the upstream Linux kernel community regarding inclusivity and respect. In his resignation, Herbst stated his belief that the open-source community should operate on principles of equality and respect, expressing his disapproval of statements made by other maintainers perceived as exclusionary. He cited the phrase "we are the thin blue line" as a particular concern, highlighting the harm such statements cause. While Red Hat developers Lyude Paul and Danilo Krummrich will continue Nouveau maintenance, Red Hat is also developing NOVA, a new Rust-based open-source NVIDIA kernel driver.

Systemd to Boot Directly from HTTP-Downloaded Disk Images

2025-02-11

Systemd lead developer Lennart Poettering is adding the ability to boot directly from a disk image downloaded via HTTP within the initial RAM disk (initrd) during the Linux boot process. Building on recent systemd additions, this allows downloading the root disk image via HTTP, attaching it to a loopback device, and mounting it. The goal is to allow pointing UEFI to a URL to load the Unified Kernel Image (UKI) and boot the root filesystem. The immediate use case is simplifying physical device testing by easily booting new root filesystems over HTTP on each boot. The work-in-progress pull request includes the initial code for this; future extensions may include NVMe-over-TCP support.

Linux 6.14 Brings Much Faster Suspend/Resume Times

2025-01-26

Linux kernel 6.14 boasts significantly faster suspend and resume times for some systems thanks to an ACPI update. The change replaces msleep() with usleep_range() in acpi_os_sleep(), reducing spurious delays caused by timer inaccuracies. Testing shows dramatic improvements, with some Dell XPS laptops seeing suspend/resume times drop from 8 seconds to around 1 second. This optimization is particularly beneficial for systems relying on short sleep times, such as those using tight loops with ASL Sleep(5ms).

Sony engineers are proposing a change to the default C++ mode in the LLVM Clang compiler, switching from C++17 to C++20. This aligns with Sony's upcoming plans to make C++20 the default for their PlayStation 5 compiler. While some C++20 test cases currently fail and Clang's C++20 support isn't yet complete, Sony intends to contribute a build/test bot to assist upstream development. This initiative aims to accelerate Clang's adoption of C++20, leading to a more efficient compilation environment for game development.
