How to count the number of data loaded into the cache but not used?

25 views Asked by At

The following two situations may cause data to be loaded into the cache but not used:

  1. Incorrect prefetch judgment
  2. Partial access of cacheline

Both of these situations may have negative impact on system performance, so I want to monitor the severity of these situations in the system.

I am using Intel 8352Y (Icelake) and AMD 9654 (Zen4).

Is there corresponding PMU events or other means to count such events on these two platforms?
