Enum perf_event::events::CacheResult

#[repr(u32)]
pub enum CacheResult {
    ACCESS,
    MISS,
}

What sort of cache result we're interested in observing.

ACCESS counts the total number of operations performed on the cache, whereas MISS counts only those requests that the cache could not satisfy. Treating MISS as a fraction of ACCESS gives you the cache's miss rate.

This is used used in the Cache type as part of the identification of a cache event. Each variant here corresponds to a particular PERF_COUNT_HW_CACHE_RESULT_... constant supported by the perf_event_open system call.

Variants

ACCESS

to measure accesses

MISS

to measure misses
