Curretly, the memory region of backed memory is directly mapped to guest's address space, however, it is not true for nvdimm device This patch let dimm device realize this fact and use DIMMDeviceClass->get_memory_region method to get the mapped memory region Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> --- hw/mem/dimm.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
