Formulas:
Local bandwidth [MBytes/s] = 1.0E-06*(DATA_CACHE_REFILLS_LOCAL_ALL+HWPREF_DATA_CACHE_FILLS_LOCAL_ALL)*64.0/time
Local data volume [GBytes] = 1.0E-09*(DATA_CACHE_REFILLS_LOCAL_ALL+HWPREF_DATA_CACHE_FILLS_LOCAL_ALL)*64.0
Remote bandwidth [MBytes/s] = 1.0E-06*(DATA_CACHE_REFILLS_REMOTE_ALL+HWPREF_DATA_CACHE_FILLS_REMOTE_ALL)*64.0/time
Remote data volume [GBytes] = 1.0E-09*(DATA_CACHE_REFILLS_REMOTE_ALL+HWPREF_DATA_CACHE_FILLS_REMOTE_ALL)*64.0
Total bandwidth [MBytes/s] = 1.0E-06*(DATA_CACHE_REFILLS_LOCAL_ALL+HWPREF_DATA_CACHE_FILLS_LOCAL_ALL+DATA_CACHE_REFILLS_REMOTE_ALL+HWPREF_DATA_CACHE_FILLS_REMOTE_ALL)*64.0/time
Total data volume [GBytes] = 1.0E-09*(DATA_CACHE_REFILLS_LOCAL_ALL+HWPREF_DATA_CACHE_FILLS_LOCAL_ALL+DATA_CACHE_REFILLS_REMOTE_ALL+HWPREF_DATA_CACHE_FILLS_REMOTE_ALL)*64.0

Profiling group to measure NUMA traffic. The data sources range from
local L2, CCX and memory for the local metrics and remote CCX and memory
for the remote metrics. There are also events that measure the software
prefetches from local and remote domain but AMD Zen provides only 4 counters.
