Make the jevents parser aware of the Unified Memory Controller (UMC) PMU and add events taken from Section 8.2.1 "UMC Performance Monitor Events" of the Processor Programming Reference (PPR) for AMD Family 19h Model 11h processors. The events capture UMC command activity such as CAS, ACTIVATE, PRECHARGE etc. while the metrics derive data bus utilization and memory bandwidth out of these events.
