Struct Mpu 

pub struct Mpu { /* private fields */ }

Represents our PMSAv7 MPU

This type is not [Send] because it is a per-core type and should not be moved across cores on an SMP system.

Implementations

impl Mpu

pub unsafe fn new() -> Mpu

Create an MPU handle

Safety

Only create one of these at any given time, as they access shared mutable state within the processor and do read-modify-writes on that state.

pub fn num_iregions(&self) -> u8

How many MPU instruction regions are there?

pub fn num_dregions(&self) -> u8

How many MPU data/unified regions are there?

pub fn is_unified(&self) -> bool

Do we have a unified MPU?

pub fn get_iregion(&mut self, idx: u8) -> Option<Region>

Get an instruction region

pub fn get_dregion(&mut self, idx: u8) -> Option<Region>

Get a data/unified region

pub fn configure(&mut self, config: &Config<'_>) -> Result<(), Error>

Configure the EL1 MPU

pub fn enable(&mut self)

Enable the MPU

pub fn disable(&mut self)

Disable the MPU
