Subject: [Xen-devel] [PATCH v2 46/48] xen/sched: support core scheduling for moving cpus to/from cpupools
Date: Fri,  9 Aug 2019 16:58:31 +0200
Message-ID: <20190809145833.1020-47-jgross@suse.com> (raw)
In-Reply-To: <20190809145833.1020-1-jgross@suse.com>

With core scheduling active it is necessary to move multiple cpus at
the same time to or from a cpupool in order to avoid split scheduling
resources in between.
