Subject: [Qemu-devel] [RFC PATCH 1/2] target-ppc: migrate interrupt vectors address for spapr VM
Date: Mon, 21 Mar 2016 15:02:07 +0100	[thread overview]
Message-ID: <1458568928-3055-2-git-send-email-clg@fr.ibm.com> (raw)
In-Reply-To: <1458568928-3055-1-git-send-email-clg@fr.ibm.com>

This address is changed by the linux kernel using the H_SET_MODE hcall
and needs to be migrated in order to restart a spapr VM running in
TCG. Other platforms should not be affected.
