Hello,
Hi Masami,
This made progress with my Xen boot on DeveloperBox (
https://www.96boards.org/product/developerbox/ ) with ACPI.
I have reviewed the patch attached and I have a couple of remarks about it.
The STAO table was originally created to allow an hypervisor to hide
devices from a controller domain (such as Dom0). If this table is not
present, then it means the OS/hypervisor can use any device listed in
the ACPI table.
Additionally, the STAO table should never be present in the host ACPI table.
Therefore, I think the code should not try to find the STAO. Instead, it
should check whether the SPCR table is present.
