Implementations

impl Perfsel

pub const fn perfsel(&self) -> Perfsel

Select an event for PERFCTR0. For each downstream port of the main crossbar, four events are available: ACCESS, an access took place; ACCESS_CONTESTED, an access took place that previously stalled due to contention from other masters; STALL_DOWNSTREAM, count cycles where any master stalled due to a stall on the downstream bus; STALL_UPSTREAM, count cycles where any master stalled for any reason, including contention from other masters.

pub fn set_perfsel(&mut self, val: Perfsel)

Select an event for PERFCTR0. For each downstream port of the main crossbar, four events are available: ACCESS, an access took place; ACCESS_CONTESTED, an access took place that previously stalled due to contention from other masters; STALL_DOWNSTREAM, count cycles where any master stalled due to a stall on the downstream bus; STALL_UPSTREAM, count cycles where any master stalled for any reason, including contention from other masters.

Trait Implementations

impl Clone for Perfsel

fn clone(&self) -> Perfsel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Perfsel

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

Formats the value using the given formatter.

impl Default for Perfsel

fn default() -> Perfsel

Returns the “default value” for a type.

impl PartialEq for Perfsel

fn eq(&self, other: &Perfsel) -> 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.
