Subject: [Qemu-devel] [for 4.1 PATCH 0/2] Disable PCIe ACS on older machines
Date: Tue, 30 Jul 2019 10:37:17 +0100 [thread overview]
Message-ID: <20190730093719.12958-1-dgilbert@redhat.com> (raw)
From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
PCIe ACS (Access Control services) got added in 4.0 and broke
migration to and from 3.1 and earlier. Fix it here
for older machine types, at the cost of breaking that compatibility
with 4.0.
Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
