[−][src]Struct x86_64::structures::paging::mapper::MappedPageTable
A Mapper implementation that relies on a PhysAddr to VirtAddr conversion function.
This type requires that the all physical page table frames are mapped to some virtual
address. Normally, this is done by mapping the complete physical address space into
the virtual address space at some offset. Other mappings between physical and virtual
memory are possible too, as long as they can be calculated as an PhysAddr
to
VirtAddr
closure.
Implementations
impl<'a, P: PhysToVirt> MappedPageTable<'a, P>
[src]
pub unsafe fn new(level_4_table: &'a mut PageTable, phys_to_virt: P) -> Self
[src]
Creates a new MappedPageTable
that uses the passed closure for converting virtual
to physical addresses.
Safety
This function is unsafe because the caller must guarantee that the passed phys_to_virt
closure is correct. Also, the passed level_4_table
must point to the level 4 page table
of a valid page table hierarchy. Otherwise this function might break memory safety, e.g.
by writing to an illegal memory location.
pub fn level_4_table(&mut self) -> &mut PageTable
[src]
Returns a mutable reference to the wrapped level 4 PageTable
instance.
