Both ACPI shutdown and ACPI PM timer devices has been moved to different
port addresses in the latest version of Cloud Hypervisor. These changes
need to be reflected on the OVMF firmware.

Requiring lockstep updates tends to be painful, so we try avoid that with qemu ...

This information is provided through the FADT/FACP as well, which is where the OS retrieves it. > > Requiring lockstep updates tends to be painful, so we try avoid that > with qemu ... Yes I understand. We've been kind of forced to update these addresses to match the ones used by QEMU since they had already been authorized in the context of TDX. It's just easier for everybody. > > (just a suggestion, not an objection) > > Acked-by: Gerd Hoffmann <kraxel@redhat.com> > > take care, > Gerd > > > > > > --------------------------------------------------------------------- Intel Corporation SAS (French simplified joint stock company) Registered headquarters: "Les Montalets"- 2, rue de Paris, 92196 Meudon Cedex, France Registration Number: 302 456 199 R.C.S.
