While GTK 4.0 has been released, there still is major work to look forward to with future GTK4 releases. One area seeing recent and ongoing improvements is with the toolkit's OpenGL renderer...
Voltage, temperature, and fan speed reporting among desktop motherboards under Linux remains one of the unfortunate areas even in 2021... Many SIO ICs remain publicly undocumented and the Linux driver support is often left up to the community and usually through reverse-engineering. Thus the mainline Linux kernel support is left to suffer especially among newer desktop motherboards. At least for Linux 5.12 some ASRock motherboards will begin seeing their voltage/temperature reporting now function...

Pyston started out as a fork of CPython and was very promising during its early days as a Dropbox project for delivering on high performance Python. Its performance was great but in 2017 Dropbox stopped supporting it. Then at the end of 2020, Pyston reappeared and Pyston 2.0 promoted ~20% faster performance than Python 3.8. Pyston 2.x was developed by many of the original developers from Dropbox now out working on their own firm...
With the Zink OpenGL-on-Vulkan implementation within Mesa on a nice upward trajectory with most recently now having the backing of a Valve contract developer and a focus on getting the backlog of patches to this Gallium3D code upstreamed, here are some fresh benchmarks looking at where the performance currently stands when using Zink atop the RADV Vulkan driver compared to using the native RadeonSI driver with this round of testing from a Radeon RX 5700 XT graphics card.
The open-source/Linux Apple M1 work continues to be quite busy this week... The latest is Alyssa Rosenzweig who has been working on reverse-engineering the M1 graphics processor has been able to write some early and primitive code for rendering a triangle...

It was just earlier this month that mainline Mesa achieved OpenGL 4.1 for Zink, the Gallium3D driver allowing OpenGL to be implemented atop Vulkan. Now OpenGL 4.2 support is in place for this promising Mesa component...
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.
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...
Even in 2021 longtime open-source AMD Mesa driver developer Marek Olšák isn't done optimizing OpenGL for delivering the best possible performance with the Radeon graphics driver. Marek's latest work includes more OpenGL threading enhancements and other work seemingly targeted at SPECViewPerf workloads...
While Ubuntu normally ships with the latest GNOME desktop as of release time, April's release of Ubuntu 21.04 will not be shipping with GNOME 40 but sticking to GNOME 3.38...
Raptor Engineering known for their work on open-source POWER9 systems has announced Kestrel, an open-source baseboard management controller (BMC) design that is open down to the HDL design and firmware...
Following November's launch of the Raspberry Pi 400 keyboard computer there is another new product from the UK foundation and it's not a new Raspberry Pi SBC...
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...
Lightworks, the professional-grade video editing system that works well on Linux but has remained elusive of its long past open-source promise, is out with its first major release of 2021...
One of the last pieces of the puzzle for supporting an entirely Vulkan-based Wayland compositor is coming together with a new extension that looks like it will be merged soon and there already being work pending against Sway/WLROOTS to make use of the Vulkan path...
If Red Hat's new no-cost offering for up to 16 production systems for RHEL doesn't fit your requirements and are evaluating alternatives to CentOS 8 that will be EOL'ed this year, Rocky Linux remains one of the leading contenders and is on track for its inaugural release in Q2 of this year...
Following a very active past couple of days, developers from security startup Corellium have followed through on their word so far of publishing the Apple Silicon patches to the Linux kernel mailing list for possible upstreaming in the future that allow the Linux kernel to boot with Apple M1 hardware...
Following the announcement at the end of last year that CentOS 8 will be ending and instead focusing on CentOS Stream as the future upstream to RHEL, there have been many concerned by the absence of CentOS 8 past this year. In trying to fill that void, Red Hat announced today they will be making Red Hat Enterprise Linux free for small production deployments...
For those still making use of pre-GCN AMD graphics cards supported by the R600 Gallium3D driver (namely the Radeon HD 5000/6000 series), the open-source "R600g" Gallium3D driver now has nearly feature complete NIR support...

For those wondering how the likes of the XanMod and Liquorix kernel spins are competing these days with the mainline Linux kernel, here are some fresh benchmarks looking at these popular derivatives of the Linux kernel. XanMod in particular atop Ubuntu can easily help squeeze extra performance out of the system as shown by these benchmarks on an AMD Ryzen 9 5900X desktop.
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...
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...
While 2021 may be the year that some desktop Linux distributions begin using PipeWire by default as the next-generation replacement to the likes of PulseAudio and JACK, for upstream PulseAudio this week it's finally seeing better/restored support for FreeBSD. PulseAudio has merged a set of patches long available via FreeBSD Ports and the like to improve the BSD audio experience...

GCC 11 entered its final stage of development today as it works towards releasing around the end of Q1 / early Q2 if their past cadence holds up. Before GCC 11.1 can debut as the first stable version, there are some 60+ "P1" high priority regressions that need to be resolved or otherwise demoted to lesser priority regressions...
