Thank you, I could enable DAX PMD suport for HPE NVDIMM modules.
The following ndctl command changed the nvdimm device type
from "namespace_io_device_type" to "nd_pfn_device_type", right?
I did the following:
------
# ndctl create-namespace --reconfig=namespace1.0 --mode=memory --force
{
"dev":"namespace1.0",
"mode":"memory",
"size":33820770304,
"uuid":"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
"blockdev":"pmem1"
}
# ndctl list --namespaces
{
"provider":"ACPI.NFIT",
"dev":"ndbus0",
"namespaces":[
{
"dev":"namespace1.0",
"mode":"memory",
"size":33820770304,
"uuid":"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
"blockdev":"pmem1"
},
{
"dev":"namespace0.0",
"mode":"raw",
"size":34359738368,
"blockdev":"pmem0"
}
]
}
