From a3ba4972f2ef8408dcc8a2a3d433621d6c990594 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 4 May 2020 16:41:53 -0700 Subject: [PATCH] torture: Add --allcpus argument to the kvm.sh script 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. Signed-off-by: Paul E.
