To cite ACPI specification:
Heterogeneous Memory Attribute Table describes the memory
attributes, such as memory side cache attributes and bandwidth
and latency details, related to the System Physical Address
(SPA) Memory Ranges. The software is expected to use this
information as hint for optimization.
According to our upstream discussion [1] this is exposed under
<numa/> as <cache/> under NUMA <cell/> and <latency> or
<bandwidth/> under numa/latencies.
