linux has numa support,and in the case of integrated memory controllers
like amd64, CONFIG_NUMA should be choice and linux support numa,is it
right? if CONFIG_NUMA is not choice ,then linux could not work well in
the case of integrated memory controllers even for amd64,is it right?
and for the paravirt xen-guest-linux do not support numa-aware now ,or
does it support numa-aware if CONFIG_NUMA choiced?
Thanks in advance
