Linux 5.12 To Allow Voltage/Temperature Reporting On Some ASRock Motherboards

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 2.1 Released With Striving For High Performance Python

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.

Zink OpenGL-On-Vulkan vs. RadeonSI OpenGL Performance As Of January 2021

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.

Linux 5.12 Set To See Support For The Nintendo 64

It's taken nearly twenty five years but the mainline Linux kernel this year will be able to boot on the Nintendo 64 game console... It's looking like the Nintendo 64 support will be merged with the upcoming Linux 5.12 kernel.

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.

More OpenGL Threading Improvements Land For Mesa 21.1

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.

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.

Vulkan Wayland Compositors Are Nearing Reality

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.

Red Hat Announces No-Cost RHEL For Small Production Environments

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.

Dbus-Broker 26 Released For High Performance D-Bus

With the BUS1 in-kernel IPC not panning out and not seeing any major code work in nearly two years, the user-space based, D-Bus compatible DBus-Broker remains the performant and current option for those looking at something faster and more reliable than D-Bus itself.
