Subject: [Qemu-devel] [PATCH v1 3/3] cpus: CPU threads are always created initially for one CPU only
Date: Fri, 9 Feb 2018 20:52:39 +0100 [thread overview]
Message-ID: <20180209195239.16048-4-david@redhat.com> (raw)
In-Reply-To: <20180209195239.16048-1-david@redhat.com>
It can never happen for single-threaded TCG that we have more than one
CPU in the list, while the first one has not been marked as "created".
