[PATCH 00/13] microvm: add acpi support

I know that not supporting ACPI in microvm is intentional.  If you still
don't want ACPI this is perfectly fine, you can use the usual -no-acpi
switch to toggle ACPI support.

These are the advantages you are going to loose then:

  (1) virtio-mmio device discovery without command line hacks (tweaking
      the command line is a problem when not using direct kernel boot).
  (2) Better IO-APIC support, we can use IRQ lines 16-23.
  (3) ACPI power button (aka powerdown request) works.
  (4) machine poweroff (aka S5 state) works.

Together with seabios patches for virtio-mmio support this allows to
boot standard fedora images (cloud, coreos, workstation live) with the
microvm machine type.


Gerd Hoffmann (13):
  acpi: make build_madt() more generic.
  acpi: factor out acpi_dsdt_add_fw_cfg()
  microvm: add isa-acpi device
  microvm: add minimal acpi support.
  microvm: add acpi_dsdt_add_virtio() for x86
  microvm: disable virtio-mmio cmdline hack
  [testing] seabios: update submodule to experimental microvm branch
  [testing] seabios: update config & build rules
  [testing] seabios: update binaries to experimental microvm branch
  microvm/acpi: add rtc
  microvm/acpi: add serial
  microvm: make virtio irq base runtime configurable
  microvm/acpi: use GSI 16-23 for virtio
