pma: Vec<Region>

The physical memory map.

Implementations

impl Hart

pub fn new(reset_pc: u64, pma: Vec<Region>) -> Self

The hart as reset leaves it: machine mode at reset_pc, interrupts off, every protection entry off, over the physical memory map pma.

pub fn mstatus(&self) -> u64

pub fn step(&mut self, bus: &mut impl Bus) -> Step

Execute one instruction. The counters count the instruction under the inhibit it leaves behind: one that writes mcountinhibit is counted (or not) by the value it writes.

Trait Implementations

impl Clone for Hart

fn clone(&self) -> Hart

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hart

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

Formats the value using the given formatter.
