Subject: [PATCH tip/core/rcu 09/23] torture: Add --allcpus argument to the kvm.sh script
Date: Mon, 22 Jun 2020 17:37:38 -0700	[thread overview]
Message-ID: <20200623003752.26872-9-paulmck@kernel.org> (raw)
In-Reply-To: <20200623003731.GA26717@paulmck-ThinkPad-P72>

From: "Paul E. McKenney" <paulmck@kernel.org>

Leaving off the kvm.sh script's --cpus argument results in the script
testing the scenarios sequentially, which can be quite slow.  However,
having to specify the actual number of CPUs can be error-prone.
This commit therefore adds a --allcpus argument that causes kvm.sh to
use all available CPUs.
