   13   The Tag-and-Data units (TADs) maintain coherence and contain CN10K
   14   shared on-chip last level cache (LLC). The tad pmu measures the
   15   performance of last-level cache. Each tad pmu supports up to eight
   16   counters.
   17 
   18   The DT setup comprises of number of tad blocks, the sizes of pmu
   19   regions, tad blocks and overall base address of the HW.
