Expand description

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

Tuple Fields

0: u32

Implementations

source

impl PDEntry

source

pub fn new(pt: PAddr, flags: PDFlags) -> PDEntry

Creates a new PDEntry.

Arguments

pt - The physical address of the page table.
flags- Additional flags for the entry.

Implementation notes

This doesn’t support PSE-36 or PSE-40.

source

pub fn address(self) -> PAddr

Retrieves the physical address in this entry.

source

pub fn flags(self) -> PDFlags

Returns the flags corresponding to this entry.

source

pub fn is_present(self) -> bool

Present; must be 1 to map a 4-MByte page.

source

pub fn is_writeable(self) -> bool

Read/write; if 0, writes may not be allowed to the 4-MByte page referenced by this entry.

source

pub fn is_user_mode_allowed(self) -> bool

User/supervisor; if 0, user-mode accesses are not allowed to the 4-MByte page referenced by this entry.

source

pub fn is_page_write_through(self) -> bool

Page-level write-through.

source

pub fn is_page_level_cache_disabled(self) -> bool

Page-level cache disable.

source

pub fn is_accessed(self) -> bool

Accessed; indicates whether software has accessed the 4-MByte page referenced by this entry.

source

pub fn is_dirty(self) -> bool

Dirty; indicates whether software has written to the 4-MByte page referenced by this entry.

source

pub fn is_page(self) -> bool

Page size; if set this entry maps a 4-MByte page; otherwise, this entry references a page directory.

source

pub fn is_global(self) -> bool

Global; if CR4.PGE = 1, determines whether the translation is global; ignored otherwise.

source

pub fn is_pat(self) -> bool

If the PAT is supported, indirectly determines the memory type used to access the 4-MByte page referenced by this entry; otherwise, reserved (must be 0)
