charset="utf-8" Currently, when defining a HMAT cache for a NUMA node (in parse_numa_hmat_cache()) there is this check that forces users to define HMAT latency/bandwidth first. There is no real need for this, because nothing in the parse function relies on that and the HMAT table is constructed way later - when ACPI table is constructed.
