[Qemu-devel] [RFC PATCH v2 00/11] Generate ACPI v5.1 tables and expose it to guest over fw_cfg on ARM

[Shannon Zhao]

This patch series generate seven ACPI v5.1 tables for machine virt on ARM.
The set of generated tables are:
- RSDP
- XSDT
- MADT
- GTDT
- FADT
- DSDT

These tables are created dynamically using the function of acpi-build-utils.c,
taking into account the needed information passed from the virt machine model.
When the generation is finalized, it use fw_cfg to expose the tables to guest.

This patchset is based on Igor Mammedov's branch which can be found at below
git tree:
 https://github.com/imammedo/qemu/commits/ASL_API_v2

And this patchset refers to Alexander Spyridakis's patches which are sent to
qemu-devel mailing list before.

Thanks to Laszlo's work on UEFI (ArmVirtualizationQemu) supporting downloading
ACPI tables over fw_cfg, we now can use ACPI in VM. I have done following vm
startup test:

xp, windows2008, sles11 on X86
Linux on ARM64

Laszlo's patch
http://thread.gmane.org/gmane.comp.bios.tianocore.devel/12158

Todo:
1) add GPIO controller in virt and expose it through ACPI
2) add cpu hotplug support

Any comments are welcome.

changes since v1:
  * fix bug found by Laszlo
  * move common helpers into dedictated file and change generating
    table order according to Igor's comments
  * fix copyright and function name according to Michael's comments
