i check the doc from https://github.com/pmem/ndctl, and get info as follows:

Compile the libnvdimm sub-system as a module, make sure "zone device"
memory is enabled, and enable the btt, pfn, and dax features of the
sub-system:
CONFIG_ZONE_DEVICE=y
CONFIG_LIBNVDIMM=m
CONFIG_BLK_DEV_PMEM=m
CONFIG_ND_BLK=m
CONFIG_BTT=y
CONFIG_NVDIMM_PFN=y
CONFIG_NVDIMM_DAX=y

it has a litte difference between them.
