EptEntry

Struct EptEntry 

Source
pub struct EptEntry(/* private fields */);
Available on x86-64 only.
Expand description

An EPT descriptor, independent of table allocation and EPTP geometry.

Implementations§

Source§

impl EptEntry

Source

pub const fn from_parts(paddr: PhysAddr, flags: EptFlags) -> Self

Encodes a host physical page and explicit hardware flags.

This does not install a translation. The table owner must validate the CPU’s physical width, large-page alignment, supported memory types, permissions and optional EPT controls before making this entry live.

Source

pub fn flags(self) -> EptFlags

Returns hardware flags without applying a VM mapping policy.
