Linux 5.11 Is Now Looking Great For AMD Zen 2 / Zen 3 Performance

Not only is the AMD "CPU frequency invariance regression" from that new support with the in-development Linux 5.11 kernel on course to address the performance shortcomings I outlined last month, but with the patched kernel for a number of workloads the performance is now ahead of where it was at with Linux 5.10.

The Unified Path Ahead For Building SUSE Linux Enterprise + openSUSE Leap

Red Hat hasn't been the only major enterprise Linux distribution shifting around their pieces with regards to how RHEL is formed with moving to CentOS Stream as its future upstream. Over the past year especially openSUSE Leap and SUSE Linux Enterprise having been moving closer together with the source trees now being more closely aligned between Leap and "SLE". SUSE has published an insightful blog post series detailing the prior way that openSUSE Tumbleweed and Leap tied in with SUSE Linux Enterprise and then the direction they have been shifting.

A Fix Has Been Proposed For The Slower AMD Performance On Linux 5.11

With the in-development Linux 5.11 kernel there are many great features and improvements especially for AMD users with some new drivers and other pleasant enhancements. But as I outlined back on Christmas day: Linux 5.11 Is Regressing Hard For AMD Performance With Schedutil. Fortunately, a fix is now en route to the Linux 5.11 kernel for fixing that performance regression affecting AMD Zen 2/3 desktops and servers.

GNOME 40 Will Now Handle XWayland On-Demand By Default

Back in 2019 support was added to GNOME 3.34 to allow starting XWayland on-demand. With this opt-in feature, XWayland support would only be started up when needed (on-demand) for running X11 clients. That support has now matured enough where for the upcoming GNOME 40 it will be enabled by default.

2021 Could Be The Year That AMD Radeon Graphics Can Hot Unplug Gracefully On Linux

It's been nearly one year that AMDGPU patches have been around to better handle GPU hot unplugging on Linux. The use-case for that being either removal via sysfs such as if then assigning the GPU to a VM or for external GPUs such as connected via Thunderbolt. Those patches are still baking but the latest iteration of the work has now been published by AMD.
