+ * Vendor Specific: HPE DIMM Current Configuration
Record
+ *
+ * This record is used to communicate information about
the currently
+ * configured memory regions on DIMMs installed in the
system.
+ *
+ * There will be at least one Type 244 Record for each
DIMM installed
+ * in the system with configured non-volatile or
volatile memory.
+ *
+ * The number of DIMM Configuration Records for each
DIMM is specified by
+ * the Configured Region Count field in its
corresponding Type 232 DIMM
+ * Capabilities record. Each record represents a memory
region on the
+ * DIMM, labeled by its Region ID. The Memory Type
field can be used to
+ * determine the currently configured memory type for
the region. When
+ * set to Volatile, the data on the memory region is
lost on a power
+ * cycle. When set to Byte Accessible Persistent, the
data on
+ * the memory region is retained through a reset. The
Region Memory Size
+ * field contains the size of the configured region in
MiB.
+ *
+ * The Passphrase State specifies the enable/disable
state of the
+ * Passphrase requirement and is only applicable when
the DIMM region is
+ * configured as Byte Accessible Persistent. The
Interleave Set Index
+ * specifies which interleave set the DIMM region
belongs to, if any.
+ * Regions with identical interleave set indices mean
the DIMM regions
+ * are interleaved. These indices should match what is
found in the DIMM's
+ * PCAT Interleave Information tables. Interleave set
indices are
+ * 1-based. This will be a unique value per interleave
set. If the DIMM
+ * region is not interleaved, the interleave set index
will
+ * still be a unique value.
