Struct x86_64::instructions::tlb::InvlpgbFlushBuilder

pub struct InvlpgbFlushBuilder<'a, S = Size4KiB>
where
    S: NotGiantPageSize,
{ /* private fields */ }

Available on crate feature instructions only.

A builder struct to construct the parameters for the invlpgb instruction.

Implementations

impl<'a, S> InvlpgbFlushBuilder<'a, S>

where S: NotGiantPageSize,

pub fn pages<T>(self, page_range: PageRange<T>) -> InvlpgbFlushBuilder<'a, T>

where T: NotGiantPageSize,

Flush a range of pages.

If the range doesn’t fit within invlpgb_count_max, invlpgb is executed multiple times.

pub unsafe fn pcid(&mut self, pcid: Pcid) -> &mut Self

Only flush TLB entries with the given PCID.

Safety

The caller has to ensure that PCID is enabled in CR4 when the flush is executed.

pub unsafe fn asid( &mut self, asid: u16 ) -> Result<&mut Self, AsidOutOfRangeError>

Only flush TLB entries with the given ASID.

Safety

The caller has to ensure that SVM is enabled in EFER when the flush is executed.

pub fn include_global(&mut self) -> &mut Self

Also flush global pages.

pub fn final_translation_only(&mut self) -> &mut Self

Only flush the final translation and not the cached upper level TLB entries.

pub fn include_nested_translations(self) -> Self

Also flush nestred translations that could be used for guest translation.

pub fn flush(&self)

Execute the flush.

Trait Implementations

impl<'a, S> Clone for InvlpgbFlushBuilder<'a, S>

where S: NotGiantPageSize + Clone,

fn clone(&self) -> InvlpgbFlushBuilder<'a, S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, S> Debug for InvlpgbFlushBuilder<'a, S>

where S: NotGiantPageSize + Debug,

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

Formats the value using the given formatter.
