Subject: [Xen-devel] [PATCH v2 24/48] xen: switch from for_each_vcpu() to for_each_sched_unit()
Date: Fri, 9 Aug 2019 16:58:09 +0200 [thread overview]
Message-ID: <20190809145833.1020-25-jgross@suse.com> (raw)
In-Reply-To: <20190809145833.1020-1-jgross@suse.com>
Where appropriate switch from for_each_vcpu() to for_each_sched_unit()
in order to prepare core scheduling.
As it is beneficial once here and for sure in future add a
unit_scheduler() helper and let vcpu_scheduler() use it.
Signed-off-by: Juergen Gross <jgross@suse.com>

V2:
- handle affinity_broken correctly (Jan Beulich)
- add unit_scheduler() (Jan Beulich)
