[Qemu-devel] [PATCH v2 0/3] pc-dimm: factor out MemoryDevice

Posted by David Hildenbrand 23 weeks ago
Right now we can only map PCDIMM/NVDIMM into guest address space. In the
future, we might want to do the same for virtio devices - e.g.
virtio-pmem or virtio-mem. Especially, they should be able to live side
by side to each other.

E.g. the virto based memory devices regions will not be exposed via ACPI
and friends. They will be detected just like other virtio devices and
indicate the applicable memory region. This makes it possible to also use
them on architectures without memory device detection support (e.g. s390x).

Let's factor out the memory device code into a MemoryDevice interface.

See the patch descriptions for details.

v1 -> v2:
- Fix compile issues on ppc (still untested O:-) )

David Hildenbrand (3):
  pc-dimm: factor out MemoryDevice interface
  machine: make MemoryHotplugState accessible via the machine
  pc-dimm: factor out address space logic into MemoryDevice code
