Subject: [rt-tests v3 02/16] cyclictest: Mimik --smp behavior with --affinity
Date: Tue, 26 Jan 2021 10:14:46 +0100 [thread overview]
Message-ID: <20210126091500.31735-3-dwagner@suse.de> (raw)
In-Reply-To: <20210126091500.31735-1-dwagner@suse.de>
Let --affinity without an argument behave in the same way as
--smp. Run a thread on each CPU. This makes cyclictest behave as the
rest of the rt-tests when --affinity is used.
