The AppArmor improvements have been merged for Linux 7.3 for this kernel security module providing per-program Linux application security controls around system resources. Most notable this cycle is being able to load user-space compressed policies...
The LLVM/Clang compiler toolchain merged overnight better support for the nearly decade-old AMD Zen 1 processors and also helps with Zen+ and Zen 2 processors too. This latest work thanks to the open-source community is for providing more informed instruction scheduling around PDEP and PEXT that end up being quite costly for these original Zen processors...
The Asahi Linux crew working to bring Linux support to Apple Silicon hardware is out today with a new status update on their initiatives, largely around Apple M3 bring-up as well as some M4/M5 achievements...
Patches sent out to the Linux kernel mailing list today can provide much more efficient Zstd compression and decompression by addressing a very unfortunate oversight in the existing code...
KSMBD as the in-kernel SMB3/CIFS server for higher performance and lower resource usage than user-space SMB/CIFS protocol implementations is becoming even more useful with the in-development Linux 7.3 kernel...
Last week I provided a look at the Intel Xeon 600 series Hyper Threading performance with the Xeon 678X "Granite Rapids WS" processor for HT/SMT on and off. That was interesting while another reader request was to look at the CPU core scaling performance for this high-end workstation processor. Here are those benchmarks for showing the performance, power, and frequency/thermal impact of the Xeon 678X when limited to 6 cores, 12 cores, 24 cores, 48 cores, and then the 48 cores + HT default configuration.
Haiku R1 Beta 5 came out in September 2026 while out today is the long-awaited sixth beta for this open-source operating system inspired by BeOS. This beta release also comes one week ahead of the project's 25th anniversary...
AMD's compiler team is proposing a new LLVM Clang compiler option, -fenable-readonly-thp for implementing instruction Transparent Huge Pages "iTHP" at compile and link-time. With -fenable-readonly-thp, they are finding more performance out of SPEC CPU, Geekbench, and other workloads from the arranging of 2MB segment alignment at link time and allowing the executable text range can be promoted to huge pages...
Earlier this month when benchmarking six Linux distributions on the new Framework Laptop 13 Pro powered by Intel Core Ultra Series 3 "Panther Lake", the performance was strangely slow on Fedora Workstation 44. When digging further into it, the performance loss was with Fedora 44 using Tuned-PPD by default where as other Linux distributions default to Power Profiles Daemon. Ultimately, after Red Hat engineers got involved, was found to be a bug within the Intel P-State kernel driver exhibited by Tuned-PPD. The latest Linux kernel already has a fix in place and will be back-ported to Fedora 44...
Armbian as the Debian/Ubuntu-derived distribution that provides an optimized platform for ARM and RISC-V single board computers is out today with a major update...
The AMD GFX1250 IP is what's used by the new Instinct MI450 series accelerators. That's been around within the Linux kernel, AMDGPU LLVM compiler back-end, and related codebases the past year. Interestingly merged yesterday is a new "gfx1250-strict" target...
