realtime-setup-2.3.2-2.fc39 RPM for x86_64

From Fedora 39 for x86_64 / r

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.
