In addition to AMD's increasing Linux kernel contributions, they are also contributing more improvements in user-space too thanks to their super-computing wins and other big enterprise deployments that are Linux-based. One of the areas talked about this week at the Linux Plumbers Conference with the GNU Tools track is how they are working to extend the DWARF debug format to better handle GPU debugging...

V druhé části článků o retrobrightingu se podíváme na samotné výsledky mého snažení. Ve většině případů je výsledek velmi uspokojivý, ale jak uvidíte v jednom případě, ne vždy je vše dokonalé.

V dnešní části seriálu o křivkách, které nalezneme v přírodě, architektuře, technice i v počítačové grafice, dokončíme popis různých typů spirál. Zabývat se budeme například klotoidou a evolventou.

While Intel is normally quite good with their new hardware support being in good shape well ahead of launch, their new code for supporting the ENQCMD functionality for the Data Streaming Accelerator (DSA) with Xeon "Sapphire Rapids" has been an exception. This summer the mainline Linux kernel disabled ENQCMD support since the code was "broken beyond repair" while now Intel engineers have sent out a new series looking to get it re-enabled...

An Open Printing micro-conference took place today during the Linux Plumbers Conference 2021 week.

While Oktoberfest was once again cancelled due to the COVID-19 pandemic (then again, due to the state of the ad industry / ad-block users we haven't had any European meet-up / open-source gathering in years), the wiesn would have kicked off this past weekend. So as is tradition, there is the Phoronix Premium Oktoberfest sale where you can join the ad-free service as a reduced rate. If you enjoy the daily, original Linux and open-source content on Phoronix with plenty of benchmarking, you can do so at a reduced rate...

With the m68k community continuing to be active around supporting the vintage Motorola 68000 series with modern open-source software, Rust has now merged support for these old processors...

Earlier this year AMD went public with prototyping CRIU support for Radeon GPUs around ROCm to be able to checkpoint/freeze running compute workloads and to then restore them at a later point. This CRIU focus is driven by their big accelerator needs and forthcoming supercomputers for migrating workloads particularly within containers. AMD continues working on CRIU support for GPUs and last week provided an update on the project...
