Struct rvemu::csr::satp::Satp

pub struct Satp { /* fields omitted */ }

Methods

impl Satp

pub fn read_mode(&self) -> Mode

Read the MODE field, which selects the current address-translation scheme.

pub fn write_mode(&mut self, mode: Mode)

Write the MODE field, which selects the current address-translation scheme.

pub fn read_asid(&self) -> Mxlen

Read the address space identifier (ASID), which facilitates address-translation fences on a per-address-space basis.

pub fn write_asid(&mut self, value: Mxlen)

Write the address space identifier (ASID), which facilitates address-translation fences on a per-address-space basis.

pub fn read_ppn(&self) -> Mxlen

Read the physical page number (PPN) of the root page table, i.e., its supervisor physical address divided by 4 KiB.

pub fn write_ppn(&mut self, value: Mxlen)

Write the physical page number (PPN) of the root page table, i.e., its supervisor physical address divided by 4 KiB.
