While Freedreno and Panfrost have been steaming ahead when it comes to open-source, reverse-engineered graphics for Arm SoCs, the Etnaviv project for targeting Vivante graphics hasn't had too much to report on recently.

[4 minuty čtení] Komunita kolem KDE vydala pravidelnou aktualizaci balíku aplikací KDE. Srpnová verze KDE Applications obsahuje hlavní novinky v aplikacích jako Dolphin, Konsole, Kate, Okular či video střižně Kdenlive. Velmi příjemnou novinkou u správce souborů Dolphin je už jeho spouštění: nově je možné použít kromě obvyklých cest také vždy a všude fungující globální klávesovou zkratku Meta+E (výchozí nastavení). Tvůrci se dále snažili zamezit – jak sami píší – nepořádku. Když Dolphin již běží, pokud otevře uživatel složku s jinou aplikací, otevře se tato v Dolphinu jako nová záložka (nikoli jako samostatné okno). Toto je nové výchozí chování, které lze v nastavení vypnout.

Not directly related to the recent AMD Zen 2 BIOS update needed to fix an RdRand problem (though somewhat related in that the original systemd bug report for faulty AMD RdRand stems from these earlier CPUs), but AMD has now decided to no longer advertise RdRand support for Family 15h (Bulldozer) and Family 16h (Jaguar) processors under Linux...

While DTrace prospects for the Linux kernel are no longer viewed as magical or groundbreaking as they once were more than a decade ago, Oracle continues to work on its DTrace port to Linux and extending its reach beyond just their "Unbreakable Enterprise Kernel" for their RHEL-cloned Oracle Linux. Oracle now says they are working towards upstreaming more work as well as getting an eBPF-based implementation for the kernel...

The Blender 2.80 release arrived at the end of July that unfortunately was too late for using that big new release in our launch-day testing of AMD's EPYC 7002 "Rome" processors but as a follow-up here are AMD EPYC 7742 performance benchmarks up against the Intel Xeon Platinum 8280 Cascade Lake as well as the AMD EPYC 7601 2P. Blender 2.80 performance is the focus of this article along with some other renderer benchmarks.

Red Hat uvedl v květnu novou verzi operačního systému Red Hat Enterprise Linux (RHEL) 8, ale její vývoj stále pokračuje rychlým tempem, a proto už nyní byla uvolněna beta verze aktualizace RHEL 8.1, která přináší zlepšení možností správy systému, nové zabezpečovací prvky a nástroje pro zvýšení vývojářské produktivity. Samozřejmostí je pak aktualizace ovladačů a oprava zjištěných chyb.
