It's not too often hearing Linus Torvalds himself raising the alarm bells over performance regressions of the Linux kernel, but that happened this evening with the ongoing Linux 6.8 merge window. Torvalds' AMD Ryzen Threadripper system suddenly was suffering from much longer build times at least as a result of new code for this kernel...

While GNU Hurd predates the Linux kernel, its hardware support has been woefully behind with very limited and dated hardware support compared to modern PC/server hardware. Not only that, its been largely x86 limited but during Q4'2023 the developers involved have made progress on x86_64 support and begun tackling AArch64 porting...

Following the Bcachefs file-system having finally been upstreamed in the Linux 6.7 kernel, with the Linux 6.8 merge window now ticking the file-system's lead developer Kent Overstreet has submitted a set of feature additions and performance optimizations to this copy-on-write (CoW) file-system...

This will allow MIPI cameras moving forward to be enumerated via the platform firmware on ACPI-based systems...

Coming out of Saarland University is Vcc, the Vulkan Clang Compiler. Vcc provides an "honest attempt to bring the entire C/C++ language family to Vulkan" as an interesting new compiler...

The new System76 Thelio Major powered by Zen 4 Threadripper is being shown off this week at CES 2024 in Las Vegas at AMD's booth. A review on the new Thelio Major workstation will also be forthcoming on Phoronix...

AMD makes heavy use of the LLVM compiler infrastructure by their graphics drivers and compute stack while the GNU Compiler Collection (GCC) has to a lesser extent supported AMD graphics targets too in the context of GPU compute / OpenMP device offloading. That AMD Radeon/Instinct support for GCC has been carried out over the years by Mentor Graphics and other stakeholders. The latest on the AMD GPU expedition for GCC is that the upcoming GCC 14 compiler will finally be supporting AMD RDNA3 (GFX11) graphics hardware...

Making use of dmidecode is the go-to way of being able to read various DIMM memory information on Linux systems like the model number, speed, and other attributes. But sadly using dmidecode is restricted to root due to needing to access /dev/mem. But it turns out there is another less reported way to receive much the same information...

The Solus 4.5 Linux distribution is out today as a big update to this original distro that is known for its Budgie desktop environment and other innovations over the years. Solus 4.5 brings some pretty big changes this time around and a nice step forward over Solus 4.4 from a half-year ago...

As anticipated Linus Torvalds went ahead and just released the Linux 6.7 kernel as the first new version of 2024...

In recent days there have been leaks about an MSI "CLAW" gaming handheld device set to be announced this coming week at CES in Las Vegas. Making this gaming handheld device interesting is that unlike the Valve Steam Deck and ASUS ROG Ally or Legion Go, it's expected to be the first handheld featuring an Intel Meteor Lake SoC. In particular, the recently launched Intel Core Ultra 7 155H. For those curious about what the performance is likely to roughly be in comparison to the AMD Ryzen Z1 Extreme, here are some benchmarks looking at the performance of these competing SoCs.
