#[repr(transparent)]
pub struct PML5Entry(pub u64);

A PML5 Entry consists of an address and a bunch of flags.

Tuple Fields

0: u64

Implementations

impl PML5Entry

pub fn new(pml4: PAddr, flags: PML5Flags) -> PML5Entry

Creates a new PML5Entry.

Arguments

• pml4 - The physical address of the PML4 table that this entry points to.
• flags - Additional flags for the entry.

pub fn address(self) -> PAddr

Retrieves the physical address in this entry.

pub fn flags(self) -> PML5Flags

pub fn is_present(self) -> bool

Is page present?

pub fn is_writeable(self) -> bool

Read/write; if 0, writes may not be allowed to the 256-TByte region, controlled by this entry (see Section 4.6)

pub fn is_user_mode_allowed(self) -> bool

User/supervisor; if 0, user-mode accesses are not allowed to the 256-TByte region controlled by this entry.

pub fn is_page_write_through(self) -> bool

Page-level write-through; indirectly determines the memory type used to access the PML4 table referenced by this entry.

pub fn is_page_level_cache_disabled(self) -> bool

Page-level cache disable; indirectly determines the memory type used to access the PML4 table referenced by this entry.

pub fn is_accessed(self) -> bool

Accessed; indicates whether this entry has been used for linear-address translation.

pub fn is_instruction_fetching_disabled(self) -> bool

If IA32_EFER.NXE = 1, execute-disable. If 1, instruction fetches are not allowed from the 256-TByte region.
