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 Igor Mammedov (1): pc: acpi: bump DSDT/SSDT compliance revision to v2 Xiao Guangrong (5): nvdimm acpi: initialize the resource used by NVDIMM ACPI nvdimm acpi: introduce patched dsm memory acpi: allow using acpi named offset for OperationRegion nvdimm acpi: let qemu handle _DSM method nvdimm acpi: emulate dsm method hw/acpi/Makefile.objs | 2 +- hw/acpi/aml-build.c | 45 +++++++- hw/acpi/ich9.c | 32 +++++ hw/acpi/nvdimm.c | 276 ++++++++++++++++++++++++++++++++++++++++++-- hw/acpi/piix4.c | 3 + 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 | 6 +- include/hw/acpi/ich9.h | 2 + include/hw/i386/pc.h | 19 ++- include/hw/mem/nvdimm.h | 44 ++++++- 13 files changed, 449 insertions(+), 42 deletions(-) -- 1.8.3.1
