Sent out on Tuesday was the modules pull request for Linux 6.13 that have some low-level improvements but it noted that the biggest kernel modules highlight wasn't in that pull request itself but had been added by way of the memory management pull. This was a change by a Microsoft engineer around caching of kernel modules into huge pages...

MIPS has begun working on the open-source compiler toolchain support for their P8700 RISC-V based processors. Initial patches posted today bring-up the MIPS P8700 RISC-V support for the LLVM compiler stack...

In prior years the Free Software Foundation (FSF) has published an Ethical Tech Giving Guide for holiday shopping where they recommend products like old AMD Opteron motherboards and USB to parallel printer cables that "respect your freedoms" and meet their strict free software definitions. Out today is their newest annual FSF Ethical Tech Giving Guide...

Now that Linux 6.12 has a fix for the Lunar Lake performance with the ASUS Zenbook I have been using for my Core Ultra 200V series Linux testing as well as there recently being an updated Intel Compute Runtime with Lunar Lake fixes, I have been working on some fresh Lunar Lake Xe2 graphics benchmarks using the very latest upstream open-source code. In today's article is exploring how the Xe2 Lunar Lake graphics is performing for OpenCL / GPU compute relative to the prior Meteor Lake Arc Graphics that were already a nice step-up over earlier Intel integrated graphics.

With GIMP 3.0-RC1 out for testing since earlier this month, the hope is that GIMP 3.0 stable will in fact ship in time for the release of Ubuntu 25.04 next April. The current GIMP 3.0 release candidate is working its way to Debian Unstable and in turn soon should be available via the Ubuntu 25.04 archive...

While the end of year holidays are fast approaching, my commitment to Linux hardware and open-source software remains and there still is a lot of interesting content to come this year still -- each and every day, without change for roughly a decade. Unfortunately though due to the (sad) state of the ad industry, many major companies focusing on the likes of Facebook/Meta ads, and the frequent use of ad-blockers by Linux/FLOSS readers make ongoing operations increasingly difficult. But if you'd like to show some love this holiday season, the Phoronix Premium "Cyber Week" / "Black Friday" special is now taking place so you can enjoy the site ad-free, native dark mode support, multi-page articles on a single page, and other benefits while hopefully allowing the site to continue for years to come...

Either due to a mistimed blog post or other factors, a big feature article is out talking up the new ROCm 6.3 features... But the updated ROCm 6.3 open-source GPU compute software doesn't appear to actually be released yet at all their usual sources. In any event there are new features and big performance gains being talked up for ROCm 6.3...

GMP (GNU MP nebo též libgmp) je otevřená knihovna pro práci s čísly v libovolně přesné aritmetice. Ve druhém článku se podíváme na umocňování, výpočet modulu nebo různé funkce z teorie čísel.
