[Qemu-devel] [RFC 0/9] generate dynamic _CRS for motherboard resources

[Igor Mammedov]

Since introduction of PCIHP, it became problematic to
punch hole in PCI0._CRS statically since PCI hotplug
region size became runtime changeable.

So replace static hole punching with dynamically consumed
resources in a child device on PCI0 bus. i.e generate
PNP0C02 device as a child of PCI0 bus at runtime and
consume GPE0, PCI/CPU hotplug IO resources in it instead
of punching holes in static PCI0._CRS.

Tested with Windows XPsp3, Vista, Windows Server 2003, 2008, 2012r2.

PS:
Series adds several ASL like macros to simplify
code for dynamic generation of AML structures.

Igor Mammedov (9):
  Revert "pc: Q35 DSDT: exclude CPU hotplug IO range from PCI bus
    resources"
  Revert "pc: PIIX DSDT: exclude CPU/PCI hotplug & GPE0 IO range from
    PCI bus resources"
  Partial revert "pc: ACPI: expose PRST IO range via _CRS"
  acpi: replace opencoded opcodes with defines
  acpi: add PNP0C02 to PCI0 bus
  acpi: consume GPE0 IO resources in PNP0C02 device
  acpi: consume CPU hotplug IO resource in PNP0C02 device
  pcihp: expose PCI hotplug MMIO base/length as properties of piix4pm
  acpi: consume PCIHP IO resource in PNP0C02 device
