  • Article

This _DSM Interface for Byte Addressable Energy Backed Function Class (Function Interface 1) function returns device-specific information. It should be implemented using an NVDIMM ACPI Namespace.

Registers are defined in the Byte Addressable Energy Backed Interface specification.

Input

Arg3

None.
