It is based on my previous patchset,
"[PATCH 0/8] nvdimm acpi: bug fix and cleanup", these two patchset are
against commit dea651a95af6dad099 (intel-iommu: Check IOAPIC's Trigger Mode
against the one in IRTE) on pci branch of Michael's git tree and can be
found at:
https://github.com/xiaogr/qemu.git nvdimm-hotplug-v3
Changelog in v3:
1) use a dedicated interrupt for nvdimm device hotplug
2) stop nvdimm device hot unplug
3) reserve UUID and handle for QEMU internally used QEMU
5) redesign fit buffer to avoid OSPM reading incomplete fit info
6) bug fixes and cleanups
Changelog in v2:
Fixed signed integer overflow pointed out by Stefan Hajnoczi
This patchset enables nvdimm hotplug support, it is used as pc-dimm hotplug,
for example, a new nvdimm device can be plugged as follows:
object_add memory-backend-file,id=mem3,size=10G,mem-path=/home/eric/nvdimm3
device_add nvdimm,id=nvdimm3,memdev=mem3
and unplug it as follows:
device_del nvdimm3
object_del mem3

nvdimm acpi: prebuild nvdimm devices for available slots
nvdimm acpi: introduce fit buffer
nvdimm acpi: introduce _FIT
pc: memhp: enable nvdimm device hotplug
