The following two situations may cause data to be loaded into the cache but not used:
- Incorrect prefetch judgment
- 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?
