== ibm,dynamic-reconfiguration-memory ==
ibm,dynamic-reconfiguration-memory is a device tree node that represents
dynamically reconfigurable logical memory blocks (LMB). This node
is generated only when the guest advertises the support for it via
ibm,client-architecture-support call. Memory that is not dynamically
reconfigurable is represented by /memory nodes. The properties of this
node that are of interest to the sPAPR memory hotplug implementation
in QEMU are described here.
ibm,lmb-size
This 64bit integer defines the size of each dynamically reconfigurable LMB.
ibm,associativity-lookup-arrays
This property defines a lookup array in which the NUMA associativity
information for each LMB can be found. It is a property encoded array
that begins with an integer M, the number of associativity lists followed
by an integer N, the number of entries per associativity list and terminated
by M associativity lists each of length N integers.
This property provides the same information as given by ibm,associativity
property in a /memory node. Each assigned LMB has an index value between
0 and M-1 which is used as an index into this table to select which
associativity list to use for the LMB. This index value for each LMB
is defined in ibm,dynamic-memory property.
ibm,dynamic-memory
This property describes the dynamically reconfigurable memory. It is a
property encoded array that has an integer N, the number of LMBs followed
by N LMB list entires.
Each LMB list entry consists of the following elements:
- Logical address of the start of the LMB encoded as a 64bit integer. This
corresponds to reg property in /memory node.
- DRC index of the LMB that corresponds to ibm,my-drc-index property
in a /memory node.
- Four bytes reserved for expansion.
- Associativity list index for the LMB that is used as an index into
ibm,associativity-lookup-arrays property described earlier. This
is used to retrieve the right associativity list to be used for this
LMB.
- A 32bit flags word. The bit at bit position 0x00000008 defines whether
the LMB is assigned to the the partition as of boot time.
