While we await the formal IBM Power11 launch in 2025, IBM engineers are already working on compiler support for "future" post-Power11 processors with the GNU Compiler Collection (GCC)...

While the latest Intel Core Ultra processors have done away with Hyper Threading (HT), Intel Xeon CPUs continue supporting HT/SMT, including with their latest Xeon 6300 series budget server processors. As the new AMD EPYC 4005 "Grado" processors also support Simultaneous Multi-Threading (SMT) and can be found at the same core/thread count count as the flagship Xeon 6369P processor, it makes for an interesting look at comparing the SMT/HT performance impact and power efficiency. Here are some benchmarks showing the Xeon 6300 against the AMD EPYC 4005 in SMT performance.

Merged minutes ago ahead of the Linux 6.16-rc3 release due out shortly was this week's batch of Kernel-based Virtual Machine (KVM) updates. Beyond the usual KVM fixes merged for the week, a bit of feature code was pulled in by Linus Torvalds for this post-merge-window phase...

While not talked about as much as the Intel CPU security mitigations, Intel graphics security mitigations have added up over time that if disabling Intel graphics security mitigations for their GPU compute stack for OpenCL and Level Zero can yield a 20% performance boost. Ubuntu maker Canonical in cooperation with Intel is preparing to disable these security mitigations in the Ubuntu packages in order to recoup this lost performance...

The 3mdeb firmware consulting firm recently hosted another one of their virtual events about open-source firmware and beer. There they talked about AMD's ongoing work around OpenSIL for open-source CPU silicon initialization. In addition, they shared work on an experimental port of OpenSIL back to Zen 1 processors...

Prominent KDE developer Nate Graham put out a blog post today reaffirming the KDE Plasma's intent that Wayland is their main focus and X11 support continues to be maintained but eventually it will go away. Nate Graham also noted around 73% of KDE Plasma 6 users are already using the Wayland session...
