While Fedora Workstation has been moving along with its Btrfs file-system usage and beginning to make greater use of its functionality, Red Hat does continue investing heavily in Stratis-Storage as their path forward for next-generation Linux storage with Red Hat Enterprise Linux. Today marks the release of Stratis 2.4...

The "char/misc" continues to be the random catch-all subsystem for the Linux kernel for drivers and buses not fitting well into other areas of the Linux kernel. Increasingly char/misc is hosting various accelerator/offload devices with the kernel still not yet introducing its own formal accelerator subsystem. With Linux 5.13 the "char/misc" pull continues to be heavy on a wide assortment of changes...

Over the past month we have been quite impressed by the performance of the EPYC 7003 series Milan processors when looking at the top-tier parts, but how does Zen 3 do for lower-tier server CPUs? Recently we were supplied with two EPYC 72F3 processors from AMD for these 8-core high performance SKUs. In our initial look at the EPYC 72F3 Linux performance is seeing how they compare to the similar previous-generation EPYC 7F32 processor.

Linux 5.11 brought mainline support for Intel Software Guard Extensions (SGX) after a lengthy mainlining process. Building off that SGX enclaves support in the mainline kernel more recently has been support for SGX with KVM virtualization and now for mainline Linux 5.13 that guest-side support is landing for KVM guests...

The drama in kernel land this week was University of Minnesota being banned from Linux kernel development over research they previously carried out looking at "hypocrite commits" and the possibility of intentionally introducing vulnerabilities (such as use-after-free bugs) into the kernel source tree. This weekend those researchers involved published an open letter to the Linux kernel community...

Right now Fedora Linux predominantly uses GCC as the default system compiler except for cases where the upstream project only supports LLVM/Clang. But moving forward packagers working on Fedora could decide to switch to using LLVM Clang for building a given package where it is worthwhile...

Blender's Cycles engine is celebrating its tenth birthday today and in marking the occasion, the Blender project has announced the ongoing work on "Cycles X" as what started as a research project in preparing this engine for the next ten years. It's a big step forward for Cycles but with Cycles X the OpenCL rendering kernels are being removed...

As we have been showing in a few articles already, Ubuntu 21.04 is in good shape performance-wise and generally coming ahead of Ubuntu 20.10 and 20.04 LTS. We've seen that on a number of systems in the lab, but how does this better performance out of Ubuntu 21.04 compare to say Intel's Clear Linux? Here are some benchmarks.

Earlier this week was a surprising Linux kernel networking commit that removed an IBM engineer as one of the driver maintainers for the IBM Power SR-IOV Virtual NIC driver. Seemingly at issue with this VNIC driver work was the developer using his personal email address in working on the driver in his off-hours. IBM has now clarified their stance on such work...

The P-State and CPUFreq "performance" governors on Linux with desktop Intel/AMD processors can be of help for gaming and other select workloads by tending to keep the CPU clock frequencies higher than the default ondemand (CPUFreq) or powersave (P-State) governors used by nearly all Linux distributions. But with Intel's new Core i9 11900K "Rocket Lake" is a dramatic difference in power and performance between the Intel P-State performance and powersave governors than what we have seen over the years with prior generations of Intel Core processors.

Ubuntu 21.04 "Hirsute Hippo" is now available...

Tomorrow's release of Ubuntu 21.04 is exciting on the desktop for Wayland by default in supported configurations and many other package updates and enhancements. But even for being a non-LTS release if you are interested in running Ubuntu Server there are some performance improvements to enjoy with newer platforms.
