Hi Michael, Igor, Paolo, Any comment?

Since 64 bit operations breaks old guests (such as windows XP), we should keep the 64 bits stuff in the private place where common ACPI operation does not touch it Xiao Guangrong (11): tests: acpi: test multiple SSDT tables tests: acpi: test NVDIMM tables acpi: add aml_create_field() acpi: add aml_concatenate() acpi: allow using object as offset for OperationRegion nvdimm acpi: initialize the resource used by NVDIMM ACPI nvdimm acpi: introduce patched dsm memory nvdimm acpi: let qemu handle _DSM method nvdimm acpi: emulate dsm method nvdimm acpi: add _CRS tests: acpi: update nvdimm ssdt table hw/acpi/Makefile.objs | 2 +- hw/acpi/aml-build.c | 33 +++- hw/acpi/nvdimm.c | 255 +++++++++++++++++++++++++++- hw/i386/acpi-build.c | 41 ++--- hw/i386/pc.c | 8 +- hw/i386/pc_piix.c | 5 + hw/i386/pc_q35.c | 8 +- include/hw/acpi/aml-build.h | 5 +- include/hw/i386/pc.h | 5 +- include/hw/mem/nvdimm.h | 36 +++- tests/acpi-test-data/pc/NFIT | Bin 0 -> 224 bytes tests/acpi-test-data/pc/NFIT.bridge | Bin 0 -> 224 bytes tests/acpi-test-data/pc/SSDT | Bin 2486 -> 2885 bytes tests/acpi-test-data/pc/SSDT-NVDIMM | Bin 0 -> 403 bytes tests/acpi-test-data/pc/SSDT-NVDIMM.bridge | Bin 0 -> 403 bytes tests/acpi-test-data/pc/SSDT.bridge | Bin 4345 -> 4745 bytes tests/acpi-test-data/q35/NFIT | Bin 0 -> 224 bytes tests/acpi-test-data/q35/NFIT.bridge | Bin 0 -> 224 bytes tests/acpi-test-data/q35/SSDT | Bin 691 -> 1090 bytes tests/acpi-test-data/q35/SSDT-NVDIMM | Bin 0 -> 403 bytes tests/acpi-test-data/q35/SSDT-NVDIMM.bridge | Bin 0 -> 403 bytes tests/acpi-test-data/q35/SSDT.bridge | Bin 708 -> 1107 bytes tests/bios-tables-test.c | 58 +++++-- 23 files changed, 400 insertions(+), 56 deletions(-) create mode 100644 tests/acpi-test-data/pc/NFIT create mode 100644 tests/acpi-test-data/pc/NFIT.bridge create mode 100644 tests/acpi-test-data/pc/SSDT-NVDIMM create mode 100644 tests/acpi-test-data/pc/SSDT-NVDIMM.bridge create mode 100644 tests/acpi-test-data/q35/NFIT create mode 100644 tests/acpi-test-data/q35/NFIT.bridge create mode 100644 tests/acpi-test-data/q35/SSDT-NVDIMM create mode 100644 tests/acpi-test-data/q35/SSDT-NVDIMM.bridge
