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.

description:
  The rteval script is a utility for measuring various aspects of
  realtime behavior on a system under load. The script unpacks the
  kernel source, and then goes into a loop, running hackbench and
  compiling a kernel tree. During that loop the cyclictest program
  is run to measure event response time. After the run time completes,
  a statistical analysis of the event response times is done and printed
  to the screen.
