  • Systemd 247 Released With Experimental Out-of-Memory Daemon, New Credentials Capability - Phoronix

    Systemd 247 is out today as the latest major version of this Linux init system. Like most systemd releases, systemd 247 is very heavy on new features. 

    Systemd 247 most notably introduces the still-experimental systemd-oomd as the out-of-memory daemon with that Linux OOMD code originally developed by Facebook and later adopted for desktop use-cases. Once stabilized, the goal of systemd-oomd is for improving the behavior when the Linux system is low on memory / under memory pressure. 

    Beyond systemd-oomd, systemd 247 now defaults to using Btrfs with systemd-homed and other enhancements as outlined below.

  • OpenZFS 2.0-RC7 Brings Better ABI Handling, Reduced Latency For Non-Interactive I/O - Phoronix

    OpenZFS 2.0 is getting quite close to release but isn't over the finish line yet and this week brings the seventh release candidate. 

    OpenZFS 2.0-RC7 is lighter than some of the past release candidates so it looks like work may be winding down. OpenZFS 2.0 is a big release with Zstd compression, mainlined FreeBSD support, various performance improvements, sequential resilvering, persistent L2ARC support, and many other changes.

  • AMD Stages More Driver Updates For New GPUs With Linux 5.11 - Phoronix

    While the Radeon RX 6800 series is now shipping that was developed under the Sienna Cichlid codename, there are other fishy codenames remaining and are seeing more work for the Linux 5.11 kernel that will officially open development in December and then likely reaching stable in February. 

    AMD on Wednesday sent out more AMDGPU kernel driver updates for Navy Flounder and Dimgrey Cavefish. Navy and Dimgrey are for unreleased AMD Radeon products that appear to be for additional RDNA 2 / Radeon RX 6000 series parts. Nothing too notable with the latest batch of updates, just more enablement churn and more device IDs added in.
