[Qemu-devel] [PATCH v2 00/11] NVDIMM ACPI: introduce the framework of QEMU emulated |

This patchset is against commit 8a1be662a69 (virtio: fix error message for
number of queues) on pci branch of Michael's git tree
and can be found at:
https://github.com/xiaogr/qemu.git nvdimm-acpi-v2
Changelog:
These changes are based on Igor's comments:
- drop ssdt.rev2 support as the memory address allocated by BIOS/OVMF
are always 32 bits
- support to test NVDIMM tables (NFIT and NVDIMM SSDT)
- add _CRS to report its operation region
- make AML APIs change be the separated patches
This is the second part of vNVDIMM implementation which implements the
BIOS patched dsm memory and introduces the framework that allows QEMU
to emulate DSM method
Thanks to Michael's idea, we do not reserve any memory for NVDIMM ACPI,
instead we let BIOS allocate the memory and patch the address to the
offset we want
IO port is still enabled as it plays as the way to notify QEMU and pass
the patched dsm memory address, so that IO port region, 0x0a18 - 0xa20,
is reserved and it is divided into two 32 bits ports and used to pass
the low 32 bits and high 32 bits of dsm memory address to QEMU
Thanks Igor's idea, this patchset also extends DSDT/SSDT to revision 2
to apply 64 bit operations, in order to keeping compatibility, old
version (<= 2.5) still uses revision 1. 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
