Name: stalld Version: 1.17 Release: 3%{?dist} Summary: Daemon that finds starving tasks and gives them a temporary boost License: GPLv2 URL: https://gitlab.com/rt-linux-tools/%{name}/%{name}.git Source0: https://gitlab.com/rt-linux-tools/%{name}/-/archive/v%{version}/%{name}-%{version}.tar.xz BuildRequires: glibc-devel BuildRequires: gcc BuildRequires: make BuildRequires: systemd-rpm-macros Requires: systemd Patch0: Start-stalld-service-as-initrc_t.patch %description The stalld program monitors the set of system threads, looking for threads that are ready-to-run but have not been given processor time for some threshold period. When a starving thread is found, it is given a temporary boost using the SCHED_DEADLINE policy. The default is to allow 10 microseconds of runtime for 1 second of clock time. %prep %autosetup -p1 %build %make_build CFLAGS="%{optflags} %{build_cflags} -DVERSION="\\\"%{version}\\\""" LDFLAGS="%{build_ldflags}" %install %make_install DOCDIR=%{_docdir} MANDIR=%{_mandir} BINDIR=%{_bindir} DATADIR=%{_datadir} VERSION=%{version} %make_install -C redhat UNITDIR=%{_unitdir} %files %{_bindir}/%{name} %{_bindir}/throttlectl %{_unitdir}/%{name}.service %config(noreplace) %{_sysconfdir}/sysconfig/stalld %doc %{_docdir}/README.md %doc %{_mandir}/man8/stalld.8* %license gpl-2.0.txt %post %systemd_post %{name}.service %preun %systemd_preun %{name}.service %postun %systemd_postun_with_restart %{name}.service %changelog * Tue Sep 20 2022 Leah Leshchinsky -
