Methods

impl PML4Entry
[src]

[]

Returns an empty set of flags.

[]

Returns the set containing all flags.

[]

Returns the raw value of the flags currently stored.

[]

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

[]

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

[]

Returns true if no flags are currently stored.

[]

Returns true if all flags are currently set.

[]

Returns true if there are flags common to both self and other.

[]

Returns true all of the flags in other are contained within self.

[]

Inserts the specified flags in-place.

[]

Removes the specified flags in-place.

[]

Toggles the specified flags in-place.

impl PML4Entry
[src]

[]

Creates a new PML4Entry.

Arguments

  • pdpt - The physical address of the pdpt table.
  • flags- Additional flags for the entry.

[]

Retrieves the physical address in this entry.

[]

Is page present?

[]

Read/write; if 0, writes may not be allowed to the 512-GByte region, controlled by this entry (see Section 4.6)

[]

User/supervisor; if 0, user-mode accesses are not allowed to the 512-GByte region controlled by this entry.

[]

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

[]

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

[]

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

[]

If IA32_EFER.NXE = 1, execute-disable. If 1, instruction fetches are not allowed from the 512-GByte region.
