Open-Source VIA Graphics Driver Hopes To Be Mainlined For Linux 5.20

25 juin 2022 à 12:09
2022 is certainly looking to be interesting on the open-source graphics driver front... You probably didn't have Imagination publishing an open-source PowerVR Vulkan driver on your 2022 bingo card nor NVIDIA working on an open-source GPU kernel driver. The latest 2022 surprise is the OpenChrome driver project is hoping to finally be mainlined in Linux 5.20 for open-source VIA graphics for those still running vintage VIA x86 hardware...

Linus Torvalds' Latest Commentary Against -O3'ing The Linux Kernel

24 juin 2022 à 20:44
This shouldn't be too surprising considering some of Linus Torvalds past commentary about compiler optimizations and bad experiences long ago with GCC, but Linus Torvalds is not interested in seeing a tunable Kconfig option for using the -O3 compiler optimization level for building the Linux kernel without substantial justification...

D3Cold-Off Power Savings Being Prepped For Intel's Linux Driver For Arc Graphics

24 juin 2022 à 19:53
Intel's open-source Linux graphics driver developers remain very busy preparing the open-source driver stack for Arc Graphics DG2/Alchemist hardware.

Linux Full Disk Encryption Performance For The AMD Ryzen 7 PRO / HP Dev One

24 juin 2022 à 15:09
One of the great defaults when installing Pop!_OS or receiving a pre-loaded laptop/desktop from System76 or the new HP Dev One is that it encourages full-disk encryption and prominently shown during the install process. I highly recommend full-disk encryption especially for laptops. As it's been a few years since running benchmarks looking at the overhead of LUKS encryption, here are some benchmarks of Pop!_OS 22.04 on the HP Dev One with the full disk encryption enabled and then a fresh install without encryption.

Fedora 37 Looks To Ship With Stratis Storage 3.1 Support

24 juin 2022 à 12:16
While many Red Hat open-source projects end up being relatively instant successes that then end up being widely adopted in the open-source community, Red Hat's Stratis Storage effort seems to be trending as one of the exceptions. Red Hat continues investing in Stratis but it doesn't seem to have the sizable adoption or widespread interest that tends to come with most of their projects. In any event, Fedora 37 later this year should ship with the newest Stratis tech...

Ubuntu Developers Have An Idea For Handling The Over-Eager Systemd OOMD App Killing

24 juin 2022 à 01:06
With the recent release of Ubuntu 22.04 LTS it is shipping systemd-oomd by default on their desktop for trying to better handle low-memory / out-of-memory situations. However, in real-world use systemd-oomd is too easily killing user-space applications like Firefox and Chrome when approaching memory pressure. This is a poor Ubuntu 22.04 user experience but the developers now have an idea for their approach to addressing this solution...
