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