| 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.
