Subject: [Xen-devel] [PATCH v2 18/48] xen/sched: make arinc653 scheduler vcpu agnostic.
Date: Fri,  9 Aug 2019 16:58:03 +0200
Message-ID: <20190809145833.1020-19-jgross@suse.com> (raw)
In-Reply-To: <20190809145833.1020-1-jgross@suse.com>

Switch arinc653 scheduler completely from vcpu to sched_unit usage.
