Subject: [Qemu-devel] [PULL 16/36] mc146818rtc: Remove reset notifiers
Date: Tue, 20 Aug 2019 08:59:35 +0200 [thread overview]
Message-ID: <1566284395-30287-17-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1566284395-30287-1-git-send-email-pbonzini@redhat.com>
From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
The reset notifiers are unreliable and recalculating the offsets
after boot causes problems with migration in cases where explicit
base times are set on the destination.
