Enum Satp

pub enum Satp {
    Bare,
    Sv39 {
        asid: u16,
        root: PAddr,
    },
    Sv48 {
        asid: u16,
        root: PAddr,
    },
    Sv57 {
        asid: u16,
        root: PAddr,
    },
}

The Supervisor Address Translation and Protection (satp) register controls supervisor-mode address translation and protection. It contains the physical address of the root page table, plus an associated Address Space Identified (ASID), which allows translation fences on an per-address-space basis.

It also specifies a mode, which dictates how addresses are translated. Available modes are Bare, Sv39, Sv48, and Sv57.

Trait Implementations

impl Clone for Satp

fn clone(&self) -> Satp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Satp

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

Formats the value using the given formatter.

impl PartialEq for Satp

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