FOSDEM, the Free Open-Source Developer Europeans' Meeting, remains one of the top open-source/Linux events in my book. Each February for this long tenured event thousands of open-source/Linux enthusiasts would gather in Brussels, Belgium for many technical and interesting talks on a wide range of subjects. Unfortunately due to the COVID-19 pandemic, FOSDEM can only take place virtually this year but that does allow for broader participation and you can enjoy all of the content online this weekend...

For those following the saga of the AMD frequency invariance regression on Linux 5.11 since the Christmas investigative benchmarking looking at the performance regressions, everything now looks like it will be buttoned up in time for the Linux 5.11 stable release. As noted yesterday, there was a curve ball this week in that the patch proposed by SUSE's Giovanni Gherdovich in January to address the frequency invariance regression was turned down by the Linux power management maintainer and instead he (Rafael Wysocki of Intel) proposed an alternative patch that instead modified the CPUFreq driver. Given it's getting late into the cycle, it's been a mad rush of re-conducting benchmarks on this new kernel patch and now it looks like that solution will be sent in the coming days for Linux 5.11.
The GNU Network Utilities (inetutils) has seen its first major release in nine years or even the first release at all in six years since the prior point release. With GNU inetutils 2.0 are several updates to common programs like ping and ifconfig...

The second point release to Ubuntu 20.04 LTS is now officially released. Notable with Ubuntu 20.04.2 LTS is the new hardware enablement (HWE) stack that brings the Linux kernel, Mesa, and related components from Ubuntu 20.10, which means better hardware support that tends to be most notable around better open-source graphics support...
Security firm Corellium has been working on enabling the Apple M1 SoC under Linux and last month they posted initial Linux kernel patches for the Apple M1. Meanwhile independent developer Hector Martin has also been working on Apple M1 enablement via crowdfunding and today he posted his initial set of Linux kernel patches for bringing up the Apple 2020 hardware under Linux...
The AMD "frequency invariance" saga with Linux 5.11 continues... While there was a patch to address the previously noted performance regression caused by the introduction of frequency invariance and seen when using the Schedutil governor, a new CPUFreq-side patch series has been proposed instead -- both of which are addressing the performance issue with this new kernel for AMD Zen 2 / Zen 3 systems...
With Mesa 21.0 releasing soon here is a look at the new features for this quarter's release of these open-source Vulkan / OpenGL driver implementations.

Fedora 34 is planning to switch to using Intel's modern Sound Open Firmware audio driver as it should be in good shape now and superior to the existing sound driver. This is ahead of Intel likely switching to the Intel SOF driver code path by default in the upstream kernel once this change has first been vetted by Fedora users...
Given the daily progress and changes made to the open-source AMDGPU Linux kernel driver and the Mesa drivers providing the open-source OpenGL (RadeonSI) and Vulkan (RADV) support, here is a look at how the Radeon RX 6800 series performance is currently for the latest Linux graphics driver code compared to the performance seen back on the November launch day for the Radeon RX 6800 and RX 6800 XT graphics cards.
