DTrace 2.0 for Gentoo
The real, mythical DTrace comes to Gentoo! Need to dynamically trace your kernel or userspace programs, with rainbows, ponies, and unicorns - and all entirely safely and in production?! Gentoo is now ready for that! Just emerge dev-debug/dtrace and you’re all set. All required kernel options are already enabled in the newest stable Gentoo distribution kernel; if you are compiling manually, the DTrace ebuild will inform you about required configuration changes. Internally, DTrace 2.0 for Linux builds on the BPF engine of the Linux kernel, so don’t be surprised if the awesome cross-compilation features of Gentoo are used to install a gcc that outputs BPF code (which, btw, also comes in very handy for sys-apps/systemd).
Documentation? Sure, there’s lots of it. You can start with our DTrace wiki page, the DTrace for Linux page on GitHub, or the original documentation for Illumos. Enjoy!

Arm Ltd. provides fast Ampere Altra Max server for Gentoo
We’re very happy to announce that Arm Ltd. and specifically its Works on Arm team has sent us a fast Ampere Altra Max server to support Gentoo development. With 96 Armv8.2+ 64bit cores, 256 GByte of RAM, and 4 TByte NVMe storage, it is now hosted together with some of our other hardware at OSU Open Source Lab. The machine will be a clear boost to our future arm64 (aarch64) and arm (32bit) support, via installation stage builds and binary packages, architecture testing of Gentoo packages, as well as our close work with upstream projects such as GCC and glibc. Thank you!

Much improved MIPS and Alpha support in Gentoo Linux
Over the last years, MIPS and Alpha support in Gentoo has been slowing down, mostly due to a lack of volunteers keeping these architectures alive. Not anymore however! We’re happy to announce that thanks to renewed volunteer interest both arches have returned to the forefront of Gentoo Linux development, with a consistent dependency tree checked and enforced by our continuous integration system. Up-to-date stage builds and the accompanying binary packages are available for both, in the case of MIPS for all three ABI variants o32, n32, and n64 and for both big and little endian, and in the case of Alpha also with a bootable installation CD.

KDE Plasma 6 upgrade for stable Gentoo Linux
Exciting news for stable Gentoo users: It’s time for the upgrade to the new “megaversion” of the KDE community desktop environment, KDE Plasma 6! Together with KDE Gear 24.05.2, where now most of the applications have been ported, and KDE Frameworks 6.5.0, the underlying library architecture, KDE Plasma 6.1.4 will be stabilized over the next days. The base libraries of Qt 6 are already available.
More technical information on the upgrade, which should be fairly seamless, as well as architecture-specific notes can be found in a repository news item. Enjoy!

Gentoo Linux drops IA-64 (Itanium) support
Following the removal of IA-64 (Itanium) support in the Linux kernel and glibc, and subsequent discussions on our mailing list, as well as a vote by the Gentoo Council, Gentoo will discontinue all ia64 profiles and keywords. The primary reason for this decision is the inability of the Gentoo IA-64 team to support this architecture without kernel support, glibc support, and a functional development box (or even a well-established emulator). In addition, there have been only very few users interested in this type of hardware.
As also announced in a news item, in one month, i.e. in the first half of September 2024, all ia64 profiles will be removed, all ia64 keywords will be dropped from all packages, and all IA-64 related Gentoo bugs will be closed.
