[Qemu-devel] [PATCH v3 00/19] ACPI reorganization for hardware-reduced support

[Samuel Ortiz <sameo@linux.intel.com>]

This patch set provides an ACPI code reorganization in preparation for
adding hardware-reduced support to QEMU.

The changes are coming from the NEMU [1] project where we're defining
a new x86 machine type: i386/virt. This is an EFI only, ACPI
hardware-reduced platform and as such we had to implement support
for the latter.

As a preliminary for adding hardware-reduced support to QEMU, we did
some ACPI code reorganization with the following goals:

* Share as much as possible of the current ACPI build APIs between
  legacy and hardware-reduced ACPI.
* Share the ACPI build code across machine types and architectures and
  remove the typical PC machine type dependency.
  Eventually we hope to see arm/virt also re-use much of that code.

The patches are also available in their own git branch [2].

v1 -> v2:
   * Drop the hardware-reduced implementation for now. Our next patch set
     will add hardware-reduced and convert arm/virt to it.
   * Implement the ACPI build methods as a QOM Interface Class and convert
     the PC machine type to it.
   * acpi_conf_pc_init() uses a PCMachineState pointer and not a
     MachineState one as its argument.

v2 -> v3:
   * Cc all relevant maintainers, no functional changes.
