Enum perf_event::events::WhichCache

#[repr(u32)]
pub enum WhichCache {
    L1D,
    L1I,
    LL,
    DTLB,
    ITLB,
    BPU,
    NODE,
}

A cache whose events we would like to count.

This is 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_... constant supported by the perf_event_open system call.

Variants

L1D

for measuring Level 1 Data Cache

L1I

for measuring Level 1 Instruction Cache

LL

for measuring Last-Level Cache

DTLB

for measuring the Data TLB

ITLB

for measuring the Instruction TLB

BPU

for measuring the branch prediction unit

NODE

(since Linux 3.1) for measuring local memory accesses
