[Qemu-devel] [PATCH 0/4] acpi: xsdt support

[Michael S. Tsirkin]

XSDT support allows using ACPI 2 features while
avoiding breaking legacy windows XP guests:
ACPI 2 tables are linked from XSDT only,
ACPI 1 tables from both RSDT and XSDT, this way
XP does not see ACPI 2 tables.

As a first step, this patchset generates v2 RSDP
and fills in XSDT matching RSDT exactly.

ARM patch is untested: I don't know how to test ARM ACPI.
Testing reports would be greatly appreciated.

Michael S. Tsirkin (4):
  acpi: add API for 64 bit offsets
  i386/acpi: collect 64 bit offsets for xsdt
  i386/acpi: add XSDT
  acpi: unify rsdp generation
