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. | ||||||||||||||||||||||||||||
