This is an RFC for making hvmloader's ACPI builder available to both the
toolstack and the hypervisor, as discussed in
http://lists.xenproject.org/archives/html/xen-devel/2016-02/msg01228.html

The series
* Removes dependency of today's builder on hvmloader interfaces
* Makes many of the tables built optionally.
* Moves tools/hvmloader/acpi directory to xen/common/libacpi
* Builds tables for PVHv2 domU guests in libxc

There is still a number of questions about this implementation, thus it's
an RFC. Examples of things that need to be discussed are

* ACPI tables are built for PVHv2 guests unconditionally. We probably want
  to make this an option.
* Not sure about header files, especially xen/common/libacpi/x86.h and 
  tools/firmware/hvmloader/{stdio.h,string.h} 
* The builder is compiled into the hypervisor even though currently
  there are no users (PVHv2 dom0 will be the one)
* Patch 19 is somewhat of a spec violation
* Makefiles are questionable
* May need changes to guests' e820 map

This is also available from git://oss.oracle.com/git/bostrovs/xen.git:acpi_rfc.

It has been tested with Linux PVHv2 (and I believe Roger tested an earlier
version with FreeBSD). No passthrough testing has been done.

(I realize that many people are busy because of Friday's freeze but I figured I'd
post it now in the hope that this may get some reading so that we can talk about
it at the hackathon)


Boris Ostrovsky (20):
  hvmloader: Provide hvmloader_acpi_build_tables()
  acpi/hvmloader: Move acpi_info initialization out of ACPI code
  acpi/hvmloader: Initialize vm_gid data outside ACPI code
  acpi/hvmloader: Decide which SSDTs to build in hvmloader
  acpi/hvmloader: Move passthrough initialization from ACPI code
  acpi/hvmloader: Collect processor and NUMA info in hvmloader
  acpi/hvmloader: Set TIS header address in hvmloader
  acpi/hvmloader: Make providing IOAPIC in MADT optional
  acpi/hvmloader: Build WAET optionally
  acpi/hvmloader: Provide address of acpi_info as an argument to ACPI
    code
  acpi/hvmloader: Translate all addresses when assigning addresses in
    ACPI tables
  acpi/hvmloader: Link ACPI object files directly
  acpi/hvmloader: Add stdio.h, string.h and x86.h
  acpi/hvmloader: Replace mem_alloc() and virt_to_phys() with memory ops
  acpi: Move ACPI code to xen/common/libacpi
  x86/vlapic: Don't try to accept 8259 interrupt if !has_vpic()
  x86: Allow LAPIC-only emulation_flags for HVM guests
  libxc/acpi: Build ACPI tables for HVMlite guests
  acpi: Set HW_REDUCED_ACPI in FADT if IOAPIC is not supported
  acpi: Make ACPI builder available to hypervisor code
