Struct TlbFlushOp

pub struct TlbFlushOp(/* private fields */);

The operation to flush TLB entries.

The variants of this structure are:

• Flushing all TLB entries except for the global entries;
• Flushing the TLB entry associated with an address;
• Flushing the TLB entries for a specific range of virtual addresses;

This is a struct instead of an enum because if trivially representing the three variants with an enum, it would be 24 bytes. To minimize the memory footprint, we encode all three variants into an 8-byte integer.

Implementations

impl TlbFlushOp

pub fn perform_on_current(&self)

Performs the TLB flush operation on the current CPU.

pub const fn for_all() -> Self

Creates a new TLB flush operation that flushes all TLB entries except for the global entries.

pub const fn for_single(addr: Vaddr) -> Self

Creates a new TLB flush operation that flushes the TLB entry associated with the provided virtual address.

pub const fn for_range(range: Range<Vaddr>) -> Self

Creates a new TLB flush operation that flushes the TLB entries for the specified virtual address range.

If the range is too large, the resulting TlbFlushOp will flush all TLB entries instead.

Panics

Panics if the range is not page-aligned or if the range is empty.

Trait Implementations

impl Clone for TlbFlushOp

fn clone(&self) -> TlbFlushOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TlbFlushOp

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

Formats the value using the given formatter.

impl PartialEq for TlbFlushOp

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