SUSE Continues Working On Linux Core Scheduling For Better Security

SUSE and other companies like DigitalOcean have been working on Linux core scheduling to make virtualization safer particularly in light of security vulnerabilities like L1TF and MDS. The core scheduling work is about ensuring different VMs don't share a HT sibling but rather only the same VM / trusted applications run on siblings of a core.

Ubuntu 20.04 LTS Continuing To Work On Python 2 Removal

The goal for Ubuntu 20.04 is to ship with Python 2 removed since Py2 will be end-of-life after the start of the year and this next Ubuntu Linux release is a Long-Term Support release, but there still are many Python 2 depending packages left currently in Debian unstable and Ubuntu's "Focal Fossa" archive.

Windows 10 vs. Ubuntu 19.10 vs. Clear Linux Performance On The Dell Ice Lake Laptop

Last month I posted benchmarks looking at the Windows 10 vs. Linux OpenGL and Vulkan graphics performance for the Ice Lake "Gen11" graphics. But for those wondering about the CPU/system performance between Windows and Linux for the Core i7-1065G7 with the Dell XPS 7390, here are those benchmarks as we compare the latest Windows 10 to Ubuntu 19.10 and Intel's own Clear Linux platform.

Steam For Linux Beta Adds Experimental Namespaces/Containers Support

Longtime Linux game developer Timothee Besset has outlined the support introduced by Valve this week in their latest Steam Linux client beta for supporting Linux namespaces / containers. This experimental functionality may in the end provide better support for 32-bit compatibility as more Linux distributions focus solely on x86_64 packages, reducing some of the fragmentation/library conflicts between some Linux distributions and Steam, and other headaches currently plaguing the Steam Linux space.

Virtual KMS Driver To Work On Virtual Refresh Rate Support (FreeSync)

Over the past year and a half the VKMS Linux DRM driver has come together as the "virtual kernel mode-setting" implementation for headless systems and other environments not backed by a physical display. Interestingly being tacked on their TODO list now is VRR (Variable Refresh Rate) support. Separately, the prominent VKMS developer is now employed by AMD.

November Is Still Bringing Many Interesting Linux Benchmarks / Milestones

Pardon for the rather slow pace of new Phoronix content over the past week (in particular, the lack of big benchmark articles) due to my wife giving birth early and being in the hospital for a few days, but the remainder of November is set to be quite exciting on the Linux/open-source performance front. Here is some of what else is on tap for November.

The FreeBSD Migration To OpenZFS Is Still Looking To Be A Great Change

Last year it was decided that FreeBSD's ZFS code would be re-based on OpenZFS (ZFS On Linux) code for ultimately better support and functionality as well as largely unifying the open-source ZFS ecosystem. While still transitioning towards the OpenZFS code-base, for FreeBSD it's still looking to be a positive move and one that will pay off for all parties involved.

Free Software Foundation Certifies Talos II With Respecting Your Freedom

The Free Software Foundation's "Respect Your Freedom" program has tended to mostly endorse products like old motherboards re-flashed with Coreboot/Libreboot along with dated networking products and obscure products like USB microphones and USB to parallel printer port cables. But today comes the Free Software Foundation's most prominent RYF endorsement.
