-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2023-20f1bdc232 2023-12-28 00:53:03.568059 -------------------------------------------------------------------------------- Name : realtime-setup Product : Fedora 38 Version : 2.4 Release : 1.fc38 URL : https://gitlab.com/rt-linux-tools/realtime-setup.git Summary : Setup RT/low-latency environment details Description : Configure details useful for low-latency environments. Installation of this package results in: - creation of a realtime group - adds realtime limits configuration for PAM - adds udev specific rules for threaded irqs and /dev/rtc access - adds /usr/bin/slub_cpu_partial_off to turn off cpu_partials in SLUB - adds net-socket timestamp static key daemon (realtime-entsk) The slub_cpu_partial_off script is used to turn off the SLUB slab allocator's use of cpu-partials, which has been known to create latency-spikes. The realtime-entsk program is a workaround for latency spikes caused when the network stack enables hardware timestamping and activates a static key. The realtime-entsk progam is activated by the systemd service included and merely enables the timestamp static key and pauses, effectively activating the static key and never exiting, so no deactivation/activation sequences will be seen. Neither the slub script or realtime-entsk are active by default. -------------------------------------------------------------------------------- Update Information: Ensure all files have a valid SPDX License identifier in source Remove Red Hat specific Makefile targets and specfile added a .gitignore -------------------------------------------------------------------------------- ChangeLog: * Tue Dec 5 2023 Clark Williams <williams@xxxxxxxxxx> - 2.4-1 - Makefile cleanups and added .gitignore - remove Red Hat Makefile targets and specfile - ensure all files have valid SPDX license identifiers - version bump -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
