|
|
|
|
There are two ARM machines where NUMA is aware: 'virt' and 'sbsa-ref'.
|
|
Both of them are required to follow cluster-NUMA-node boundary. To
|
|
enable the validation to warn about the irregular configuration where
|
|
multiple CPUs in one cluster have been associated with different NUMA
|
|
nodes.
