Cohen: gccrs: An alternative compiler for Rust

corbet — Fri, 08 Nov 2024 15:04:37 +0000

Arthur Cohen has posted a detailed introduction to the gccrs project on the Rust Blog, seemingly with the goal of convincing the Rust community about the value of the project.

Likewise, many GCC plugins are used for increasing the safety of critical projects such as the Linux kernel, which has recently gained support for the Rust programming language. This makes gccrs a useful tool for analyzing unsafe Rust code, and more generally Rust code which has to interact with existing C code. We also want gccrs to be a useful tool for rustc itself by helping pan out the Rust specification effort with a unique viewpoint - that of a tool trying to replicate another's functionality, oftentimes through careful experimentation and source reading where the existing documentation did not go into enough detail.

(LWN last looked at gccrs in October).

Funding restored for man-page maintenance

corbet — Wed, 06 Nov 2024 15:48:15 +0000

Man pages maintainer Alejandro Colomar announced in September that he was suspending his work due to a lack of support. He has now let it be known that funding has been found for the next year at least:

We've been talking for a couple of months, and we have already agreed to sign a contract through the LF [Linux Foundation], where a number of companies provide the funds for the contract. The contract will cover the next 12 months for the agreed amount, and we should sign it in the following days. Since I've already seen a draft of the contract, and it looks good, I've already started maintaining the project again, starting on Nov 1st.

LXQt 2.1.0 released

jzb — Tue, 05 Nov 2024 15:17:48 +0000

Version 2.1.0 of the LXQt lightweight Qt desktop environment has been released. The highlight of this release is support for multiple Wayland compositors:

Through its new component lxqt-wayland-session, LXQt 2.1.0 supports 7 Wayland sessions (with Labwc, KWin, Wayfire, Hyprland, Sway, River and Niri), has two Wayland back-ends in lxqt-panel (one for kwin_wayland and the other general), and will add more later. All LXQt components that are not limited to X11 — i.e., most components — work fine on Wayland. [...]

Of course, the X11 session will be supported indefinitely. Wayland is optional and rather experimental.

The BPF instruction set architecture is now RFC 9669

corbet — Tue, 05 Nov 2024 14:43:37 +0000

After a couple of years of effort, the BPF instruction set architecture has been accepted as RFC 9669, giving it a standard outside of the in-kernel implementation. This message from David Vernet (who also contributed an article on the standardization process last year) describes the process and why it is important:

Though some vendors have already implemented BPF offloading capabilities without having a standardized ISA, others are not quite as risk tolerant. As Christoph [Hellwig] discussed at LSFMM 2022, certain NVMe vendors have expressed an interest in building BPF offloading capabilities for various use cases such as eXpress Resubmission Path (XRP), but they simply can't fund such a project without certain components of BPF being standardized. Hence, the effort to standardize BPF was born.
