Changelog in v3:
- introduce get_vmstate_memory_region() callback to abstract the difference
between pc-dimm and nvdimm addressing Stefan's suggestion
Changelog in v2:
Thanks for Stefan's review, the changes in this version are:
- rename nvdimm device parameter 'reserve-label' to 'label-size' to
specify the size of label
- add comment to explain why assert() used in nvdimm_assert_rw_label_data()
is safe
- follow the code style of 'foo() return;' if nothing is returned by fool()
- fix the value of "Non-existing-Memory-Device"
- fix the handling the DSM functions we currently did not support
This patchset is against commit cc973937f47a33 (virtio: move bi-endian
target support to a single location ) on pci branch of Michael's git tree
and can be found at:
https://github.com/xiaogr/qemu.git nvdimm-label-v3
This is the last part of vNVDIMM implementation which introduces nvdimm
label support
Currently Linux NVDIMM driver does not support namespace operation on this
kind of PMEM, apply below changes to support dynamical namespace:
