One of the very convenient features for Ubuntu Linux users who want to run the very newest upstream kernel releases or simply test a new kernel build for verifying bug fixes or functionality has been the Ubuntu Mainline Kernel PPA. It's been around for years, backed by Canonical, and very convenient for fetching pre-built AArch64 / ARM / POWER / RISC-V / x86_64 kernel binaries as Debian packages... With options of stable/test kernel versions as well as daily packages. Sadly, it's been broken once again and has been in that manner since mid-September...

Intel software engineers have been very busy recently with upstreaming various elements of support into the Linux kernel, open-source compilers and more for the next-generation Xeon Diamond Rapids processors. Following the recent GCC prep patches for Diamond Rapids to work on the ISA additions around AMX-AVX512, AMX-FP8, AMX-FP32, and others, a new patch was posted today for actually exposing the "-march=diamondrapids" compiler target and in turn confirming all of the new ISA capabilities...

October is now in the books after writing 247 original news articles and another 24 Linux hardware reviews / featured multi-page benchmark articles.

Nejnovější vydání linuxové distribuce Fedora je sice obyčejnou evolucí, ale evolucí zpříjemňující život uživatele v několika podstatných oblastech. Vévodí jí samozřejmě nové GNOME 47.

With the AMD EPYC 9005 "Turin" series launch earlier this month there was launch-day benchmark review results for the EPYC 9575F, EPYC 9755, and EPYC 9965 processors in looking at that frequency optimized SKU, the new flagship 128-core Turin "classic" core model, and the new flagship 192-core Turin "dense" core SKU, respectively. That's interesting for looking at the new 5th Gen AMD EPYC top-end wares but in comparing to 4th Gen EPYC also means higher core counts at the top-end. In being curious about the core-for-core advantages of 5th Gen EPYC, I managed to get my hands on the AMD EPYC 9655 processors for seeing how that model compares to the prior AMD EPYC 9654 "Genoa" flagship model. Here's a look today at how the AMD EPYC 9655 1P/2P 96-core processor compares to the prior EPYC 9654 flagship.
