For many years it's been possible to run Linux games on FreeBSD along with other Linux applications thanks to FreeBSD's "Linuxulator" Linux binary compatibility layer. With that more recently it's becoming possible to run even more recent games thanks to improvements to FreeBSD's graphics drivers, the Linux binary compatibility code, and other FreeBSD improvements -- Steam is even working out for more titles...

Back in February we covered Google's work on the Lyra voice/audio codec designed for fitting with very low bit-rate audio for speech compression in use-cases like WebRTC and video chatting even on the most limited Internet connections. Thanks to leveraging machine learning, Lyra can function at just 3kbps. The code to Lyra is now public...

AMD last week published a security whitepaper on Zen 3's Predictive Store Forwarding (PSF) functionality introduced with Ryzen 5000 series and EPYC 7003 series processors. In the whitepaper they mentioned Linux patches were published for allowing this feature to be disabled if concerned about the security risk, well, today those patches were made public...

Over the past two years we have seen a lot of Intel Linux kernel graphics driver work in preparing to support Intel discrete graphics cards. That work is still ongoing even for the DG1 graphics card that has been sampling to customers while Linux 5.13 will take things another step forward this summer...

While Skylake was introduced a half-decade ago already, Intel's open-source engineers aren't done relentlessly optimizing for it and subsequent 14nm processors. Hitting the GCC 11 open-source compiler today was an optimization for benefiting Skylake through the likes of Cascade Lake with some possible performance benefits...

Newer Gigabyte motherboards may soon enjoy a new Linux driver for exposing component temperatures...

The KDE project and the open-source Linux community has been in a sticky situation with The Qt Company having moved Qt 5.15 LTS to its commercial-only phase while most free software hasn't even been ported yet to Qt 6 let alone a number of modules and other features still missing from the Qt 6 tool-kit. So until the KDE project has fully transitioned to using the Qt 6 tool-kit, the project has taken up maintaining their own collection of Qt 5.15 patches...

While PipeWire is being increasingly looked at by desktop Linux distributions as the future of audio/video stream handling on the Linux desktop, aside from Fedora most Linux distributions are so far being cautious in replacing PulseAudio. In any event, PulseAudio is showing no signs of letting up and continues seeing new feature development...

While AMD's open-source Linux graphics driver developers have been working publicly on the "Acturus" GPU support going back to 2019 that was then introduced last year in the form of the Instinct MI100, finally today has the necessary binary firmware been upstreamed into linux-firmware.git for enabling the rest of the open-source AMD Linux driver stack...

Linus Torvalds put out Linux 5.12-rc6 on schedule even with the Easter holiday and it's a delightfully small update...

This past week AMD published a security analysis of AMD Zen 3's new Predictive Store Forwarding (PSF) functionality. In there they did acknowledge there is the possibility where bad PSF functionality could lead to a side-channel attack albeit the real-world exposure would be quite low. In any case they are allowing interested users to disable the Predictive Store Forwarding functionality, but what they didn't comment on in that paper was what performance overhead to expect if disabling PSF. So my Easter weekend turned into AMD Zen 3 PSF benchmarking.

The past year there has been work led by Greg Kroah-Hartman on a "READFILE" system call for efficiently reading small files such as for data exposed via sysfs. While not yet mainlined, this week the patches for this new system call were re-based giving us hope that perhaps we'll see it with Linux 5.13...
