Struct TranslationCache 

#[repr(C)]
pub struct TranslationCache {
    pub entries: [TlbEntry; 64],
}

The table compiled code indexes.

Fields

entries: [TlbEntry; 64]

Implementations

impl TranslationCache

pub const fn index(addr: u64) -> usize

The slot an address maps to.

pub fn flush(&mut self)

Drops every cached translation.

Called for any change to which pages exist or where they live. It is deliberately the blunt instrument: mapping is a setup-time operation and a mis-scoped invalidation here would be a use-after-free in compiled code.

pub fn insert(&mut self, addr: u64, host: *mut u8)

Caches host as the address of the page holding addr.

Safety

host must be the start of a page allocation that stays live and in place until the next flush.

pub fn lookup(&self, addr: u64) -> Option<*mut u8>

The host address of addr, if it is cached.
