This week marks one year since Intel formally introduced their Xeon Scalable "Ice Lake" processors led by the flagship Xeon Platinum 8380. Given the occasion, here are benchmarks looking at the Linux performance at-launch across CentOS, Clear Linux, and Ubuntu and then again against those latest Linux distributions in their current state now for seeing how the Linux performance has evolved over the past year.

Adding to the interesting changes being worked on for Fedora 37 due out later this year is the removal of legacy X.Org drivers. Fedora is looking at removing the legacy graphics driver paths that are incompatible with running Wayland...

OpenSSH 9.0 is available today as the latest version of this widely-used, open-source SSH implementation. With OpenSSH 9.0 comes new features as well as changes like scp using the SFTP protocol by default...

The Raspberry Pi Foundation on Thursday introduced an updated version of its Raspberry Pi OS operating system derived from Debian Bullseye...

Mainlined into the Linux kernel last year was the Aquacomputer HWMON driver initially for their D5 Next water cooling pump. That driver was then extended to support the Aquacomputer Farbwerk 360 RGB controller and now for Linux 5.19 is extended to also support Aquacomputer's OCTO fan controller...

Building off last week's FreeBSD 13.1 release candidate, a second release candidate has been issued ahead of this incremental FreeBSD operating system update due to be formally released before month's end...

Added back in 2019 to the Linux staging area was the "WFX" WiFi driver for low-power IoT hardware from Silicon Labs. After three years of hard work by Silicon Labs engineers and open-source developers, this driver for the WF200 series of wireless chips is set to be promoted in the Linux 5.19 cycle...

Earlier this week was the news of AMD acquiring Pensando in a $1.9B deal expected to close in Q2. The acquisition announcement isn't slowing down their efforts with today bringing the latest version of their Linux kernel patches for bringing up the Elba SoC...

ADLINK Technology today announced a new developer platform based on Ampere Altra for software development, cloud, and related workloads. The ADLINK Ampere Altra Developer Platform is based on their COM-HPC module and pairs with 32, 64, or 80-core Ampere Altra processors...

It's been nearly one year since Khronos released OpenCL 3.0 while today they are shipping some improvements to the OpenCL Software Developer Kit (SDK)...

Merged into Mesa 22.1-devel this morning is Kopper, a big improvement particularly for the Zink OpenGL-on-Vulkan driver code...

Last year Fedora developers and users were discussing the packaging of ROCm components to make it easier to deploy this Radeon open-source GPU compute stack. Five months later, some of the Radeon Open eCosystem components have made it into Fedora for easier installation but the HIP and OpenCL front-ends to ROCm haven't yet been successfully packaged...

Linux 5.18 is bringing many random/RNG improvements thanks to the work of kernel developer Jason Donenfeld. One of the changes though that had to be backed out during the merge window was trying to get /dev/random and /dev/urandom to behave exactly the same. While reverted for now with the 5.18 code, Donenfeld has prepared a change that should get it into good shape for major architectures with the next kernel cycle...

We are less than one week out from the Linux 5.18 merge window having ended and already the first pull request of "drm-misc-next" material has been submitted to DRM-Next for staging until the Linux 5.19 cycle rolls around in late May...

Google engineer Yu Zhao has sent out the "v10" patches of the MGLRU Linux kernel feature for enhancing system performance and especially for providing a better experience in dealing with system memory pressure...

As a Linux kernel change for benefiting AMD CPUs going back to Zen 1 and for matching behavior Intel has had in place since the Core 2 times, AMD submitted a patch for having the Linux kernel use the MWAIT instruction instead of HALT for when the system isn't using the CPU idle driver either for C-states being disabled by the BIOS or the driver not part of the kernel build. In turn this can lead to around a 21% improvement in exit latency on affected systems...

Here is a combination not normally expected... Microsoft engineers have submitted patches for review enabling AMD GPU hot-plugging support with the Radeon "AMDGPU" Linux kernel driver...

At the end of March Ubuntu 22.04 "Jammy Jellyfish" successfully transitioned from the former Mesa 21.3 series to Mesa 22.0 as the current stable series for these open-source OpenGL/Vulkan drivers. There are also a few changes to mention with Ubuntu 22.04's Mesa support this LTS cycle...

Back in February AMD engineers sent out a "request for comments" on x2APIC virtualization (x2AVIC) support. Those patches have now been refined beyond the RFC state and sent out today as a patch series for further review on the Linux kernel mailing list...

Tachyum is a startup working on "the world's first universal processor" that can be used from AI to HPC to hyperscale computing needs. The Tachyum processor aims to replace the needs of discrete TPUs / GPUs / XPUs into a single homogeneous processor architecture. While still running as an emulated platform, Tachyum has announced that in addition to Linux they have managed to boot and run FreeBSD on their ISA...
