Name: realtime-setup Version: 2.1 Release: 1%{?dist} License: GPLv2 Summary: Setup RT/low-latency environment details Source0: https://jcwillia.fedorapeople.org/realtime-setup-%{version}.tar.bz2 URL: https://gitlab.com/rt-linux-tools/realtime-setup.git BuildRequires: gcc BuildRequires: make BuildRequires: systemd BuildRequires: systemd-rpm-macros BuildRequires: annobin Requires: pam Requires: kexec-tools Requires: tuna Requires: tuned Requires: tuned-profiles-realtime Requires: systemd # disable generation of debuginfo packages for this package # the only executable from this package is realtime-entsk and it's not really # something that requires debugging. %global debug_package %{nil} %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. %prep %setup -q %build %make_build all %install %make_install DEST=%{buildroot} install %post /usr/sbin/groupadd -f -g 71 realtime %preun %systemd_preun realtime-setup.service %files %config(noreplace) %{_sysconfdir}/security/limits.d/realtime.conf %config(noreplace) %{_sysconfdir}/udev/rules.d/99-rhel-rt.rules %config(noreplace) %{_sysconfdir}/sysconfig/realtime-setup %{_bindir}/slub_cpu_partial_off %{_sbindir}/realtime-entsk %{_sbindir}/kernel-is-rt %{_unitdir}/realtime-setup.service %{_bindir}/realtime-setup %{_unitdir}/realtime-entsk.service %license gpl-2.0.txt %changelog * Wed Mar 27 2019 Clark Williams 2.1.1 - build for RHEL 8.1.0 - added OSCI gating test framework Resolves: rhbz#1682427 * Tue Oct 23 2018 Clark Williams 2.0.10 - rebuild to see if build-id continues to appear in the rpm * Mon Sep 24 2018 Clark Williams 2.0.9 - fix annocheck static source analysis errors Resolves: rhbz#1619407 * Fri Sep 14 2018 Clark Williams 2.0.8 - fix some coverity complaints about shell scripts Resolves: rhbz#1619407 * Fri Sep 14 2018 Clark Williams 2.0.7 - strip rt-entsk executable on installation Resolves: rhbz#1619407 * Fri Aug 24 2018 Clark Williams 2.0.6 - check for open failure to make coverity happy Resolves: rhbz#1619407 * Fri Aug 24 2018 Clark Williams 2.0.5 - move pidfile write to after daemonize in rt-entsk Resolves: rhbz#1619407 * Wed Aug 22 2018 Clark Williams 2.0.4 - add logic to write a pid file in rt-entsk (keep systemd happy) Resolves: rhbz#1619407 * Wed Aug 22 2018 Clark Williams 2.0.3 - sync with rhel-7.6 build Resolves: rhbz#1619407 * Wed Aug 22 2018 Clark Williams 2.0.2 - fix installation of rt-entsk Resolves: rhbz#1619407 * Mon Aug 20 2018 Clark Williams 2.0.1 - build for RHEL 8.0.0 - add rt-entsk program for forcing network timestamps enabled Resolves: rhbz#1619407 * Wed Aug 08 2018 Clark Williams 1.59-8 - remove libcgroup requirement - remove comment about irqbalance * Fri Jun 01 2018 Luis Claudio R.
