The kernel graphics driver for the Apple M1 and M2 GPUs is, rather famously, written in Rust, but it has achieved conformance with various graphics standards, which is also noteworthy. At the X.Org Developers Conference (XDC) 2024, Alyssa Rosenzweig gave an update on the status of the driver, along with some news about the kinds of games it can support (YouTube video, slides). There has been lots of progress since her talk at XDC last year (YouTube video), with, of course, still more to come.

Rong Xu and Han Shen described the kernel-optimization techniques that Google uses in the toolchains track at the 2024 Linux Plumbers Conference. They talked about automatic feedback-directed optimization (AutoFDO), which can be used with the Propeller optimizer to produce kernels with better performance using profile information gathered from real workloads. There is a fair amount of overlap between these tools and the BOLT post-link optimizer, which was the subject of a talk that directly preceded this session.

Security updates have been issued by AlmaLinux (kernel, python3.12, and python3.9), Debian (activemq, chromium, libheif, nss, and twisted), Fedora (chromium, dnsdist, dotnet8.0, edk2, glibc, libdigidocpp, mbedtls3.6, NetworkManager-libreswan, oath-toolkit, podman-tui, prometheus-podman-exporter, python-fastapi, python-openapi-core, python-platformio, python-rpyc, python-starlette, rust-pyo3, rust-pyo3-build-config, rust-pyo3-ffi, rust-pyo3-macros, rust-pyo3-macros-backend, suricata, thunderbird, and yarnpkg), Mageia (cpanminus, libgsf, mozjs78, redis, and thunderbird), Oracle (firefox, python3.12, python3.9, and python39:3.9 and python39-devel:3.9), Red Hat (edk2, grafana, httpd, httpd:2.4, and mod_jk), and SUSE (nodejs-electron, python3, python310, and python39).

A pair of talks in the toolchains track at the 2024 Linux Plumbers Conference covered different tools that can be used to optimize the kernel. First up was Maksim Panchenko to describe the binary optimization and layout tool (BOLT) that Meta uses on its production kernels. It optimizes the kernel binary by rearranging it to improve its code locality for better performance. A subsequent article will cover the second talk, which looked at automatic feedback-directed optimization (AutoFDO) and other related techniques that are used to optimize Google's kernels.

Greg Kroah-Hartman has announced the release of the 6.11.3, 6.10.14, 6.6.55, and 6.6.56 stable kernels. The 6.6.56 release fixes a problem with building perf in 6.6.55; "If you do not use the perf tool in the 6.6.y tree, there is no need to upgrade.". Meanwhile, 6.10.14 is the last of the 6.10.y series, so users should now be moving to 6.11.y. Other than 6.6.56, they contain the usual long list of important fixes throughout the kernel tree.

The open-source vector-graphics editor, Inkscape, is expected to release version 1.4 in October. The release represents an evolutionary step for the program, which brings new features, user-interface improvements, new and improved file-format support, and important changes to the code base. The changes in this release should improve the user experience for both casual and professional designers, and make Inkscape more compatible with proprietary vector-graphics software, including Adobe Illustrator and Affinity Designer.

The 6.11.1, 6.10.12, 6.6.53, and 6.1.112 stable kernels have been released. Each contains important fixes and users of those series should upgrade.

The most recent major release of the Tcl/Tk language and graphical-user-interface toolkit, Tcl/Tk 9.0, has been released, a mere 27 years after the 8.0 major release in 1997. There have been plenty of releases in the interim, though, as can be seen in the Tcl chronology. The 9.0 release brings 64-bit data values, better Unicode support, the ability to use zip files as filesystems, a switch to use epoll() or kqueue() where they are available, SVG support in Tk, access to notifications and other desktop-platform services in Tk, and lots more. For more information, see the release notes for Tcl and Tk that can be downloaded as Markdown files from the announcement page. (Thanks to Matt Bradley.)

The online-privacy-focused Tor project has announced that it has "joined forces and merged operations" with the Tails OS Linux distribution.

Countering the threat of global mass surveillance and censorship to a free Internet, Tor and Tails provide essential tools to help people around the world stay safe online. By joining forces, these two privacy advocates will pool their resources to focus on what matters most: ensuring that activists, journalists, other at-risk and everyday users will have access to improved digital security tools.

In late 2023, Tails approached the Tor Project with the idea of merging operations. Tails had outgrown its existing structure. Rather than expanding Tails's operational capacity on their own and putting more stress on Tails workers, merging with the Tor Project, with its larger and established operational framework, offered a solution. By joining forces, the Tails team can now focus on their core mission of maintaining and improving Tails OS, exploring more and complementary use cases while benefiting from the larger organizational structure of The Tor Project.
