KCGroups
KCGroups
This library allows easy access to currently running applications and their control groups resources, using the systemd dbus API.
More info here: https://www.freedesktop.org/software/systemd/man/systemd.resource-control.html
Introduction
To control an application's cgroup resources, use KApplicationScope.
To find a list of currently running applications, use KApplicationScopeLister.
For use in QML, KApplicationScopeListModel is provided to interact with an updated list of KApplicationScope's.
Requirements
- systemd >= 238 (for neon I used this PPA: https://launchpad.net/~ddstreet/+archive/ubuntu/systemd-upstream)
systemd.unified_cgroup_hierarchy=1
on the kernel command line (in /etc/default/grub)Delegate=cpu
in/etc/systemd/system/user@.service.d/override.conf
to be able to control CPU resources from user systemd- install
dbus-user-session
to get the user systemd instance to connect to the session bus - run applications in systemd scopes by starting them with
systemd-run --user --scope --unit org.kde.krun-<app_name>-<uuid>.desktop -- <app>
. There is a currently a patch to letKRun
launch apps this way
