Yeah, the mk_dsdt is just a middle result of compilation which is used
to generate DSDT table.

OK. Let me elaborate a bit on this.

The two macros basically imply everything enclosed in them is subject to
change. I guess I can live with this because this is not a public facing
interface for library users.

Can you ack or nack my assessment?

It needs GUEST_MAX_VCPUS in mk_dsdt.c while the GUEST_MAX_VCPUS is
defined under #if defined(__XEN__) || defined(__XEN_TOOLS__) in
xen/include/public/arch-arm.h

Why is this needed? Which unstable hypervisor interface you need in
order to build this?

[Xen-devel] [PATCH v3 05/17] libxl/arm: Generate static ACPI DSDT table

2016-07-04 Thread Shannon Zhao

From: Shannon Zhao 

It uses static DSDT table like the way x86 uses. Currently the DSDT
table only contains processor device objects and it generates the
maximal objects which so far is 128.
