Looking at the source code in numa.c I see at the start of
do_init_bootmem() that parse_numa_properties() is called. It
appears to
be looking at memory nodes and getting the node id from it. It gets
an
associativity property for the memory node and indexes that array
with a
'min_common_depth' value to get the node id.
This node id is then used to setup the active ranges in the
early_node_map[].
Is this what you are asking about? There are others I am sure who
know
more about it then I though.
I was wondering if this was documented anywhere (like in sPAPR)?
