From 76821af8b6d74237718fb554ae1a96f969308c69 Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Tue, 8 Sep 2020 18:47:14 -0400 Subject: [PATCH 2/4] target/arm: Move start-powered-off property to generic CPUState MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Laurent Vivier Message-id: <20200908184716.1125192-2-lvivier@redhat.com> Patchwork-id: 98299 O-Subject: [RHEL-AV-8.3.0 qemu-kvm PATCH 1/3] target/arm: Move start-powered-off property to generic CPUState Bugzilla: 1849483 RH-Acked-by: Miroslav Rezanina RH-Acked-by: David Gibson RH-Acked-by: Greg Kurz From: Thiago Jung Bauermann There are other platforms which also have CPUs that start powered off, so generalize the start-powered-off property so that it can be used by them. Note that ARMv7MState also has a property of the same name but this patch doesn't change it because that class isn't a subclass of CPUState so it wouldn't be a trivial change. This change should not cause any change in behavior.
