Hardware counters.

These are counters implemented by the processor itself. Such counters vary from one architecture to the next, and even different models within a particular architecture will often change the way they expose this data. This is a selection of portable names for values that can be obtained on a wide variety of systems.

Each variant of this enum corresponds to a particular PERF_COUNT_HW_… value supported by the perf_event_open system call.

Variants

CPU_CYCLES = 0

Total cycles.

INSTRUCTIONS = 1

Retired instructions.

CACHE_REFERENCES = 2

Cache accesses.

CACHE_MISSES = 3

Cache misses.

BRANCH_INSTRUCTIONS = 4

Retired branch instructions.

BRANCH_MISSES = 5

Mispredicted branch instructions.

BUS_CYCLES = 6

Bus cycles.

STALLED_CYCLES_FRONTEND = 7

Stalled cycles during issue.

STALLED_CYCLES_BACKEND = 8

Stalled cycles during retirement.

REF_CPU_CYCLES = 9

Total cycles, independent of frequency scaling.

Trait Implementations

impl Clone for Hardware

fn clone(&self) -> Hardware

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Hardware

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Hardware> for Event

fn from(hw: Hardware) -> Event

Converts to this type from the input type.

impl PartialEq for Hardware

fn eq(&self, other: &Hardware) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Hardware

impl Eq for Hardware

impl StructuralPartialEq for Hardware
