Static namespaces can be emitted without a label.  Linux needs this to

This is Linux specific? As i did not see it has been documented in the
spec...

I expect most NVDIMMs, especially existing ones available today, do
not have a label area.  This is not Linux specific and ACPI 6 does not
specify a label area, only the Intel DSM Interface Example.


Yup, label data is accessed via DSM interface, the spec I mentioned
is Intel DSM Interface Example.

However, IIRC Linux NVDIMM driver refused to use the device if no
DSM GET_LABEL support, are you going to update it?
