Struct VirtualMemoryManager 

pub struct VirtualMemoryManager { /* private fields */ }

Virtual memory manager for a process

Implementations

impl VirtualMemoryManager

pub fn new() -> Result<Self, KernelError>

Create a new virtual memory manager

pub fn new_kernel() -> Result<Self, KernelError>

Create a kernel virtual memory manager

pub fn map( &mut self, virt: VirtualAddress, phys: PhysicalAddress, flags: PageFlags, size: PageSize, ) -> Result<(), KernelError>

Map a virtual address to a physical address

pub fn unmap(&mut self, virt: VirtualAddress) -> Result<(), KernelError>

Unmap a virtual address

pub fn map_guard_page( &mut self, virt: VirtualAddress, ) -> Result<(), KernelError>

Map a guard page at the given virtual address.

A guard page is an unmapped page that triggers a page fault on access, used to detect stack overflows. The page is left unmapped (no physical backing) so any read/write/execute will trap.

pub fn translate(&self, virt: VirtualAddress) -> Option<PhysicalAddress>

Translate a virtual address to physical

pub fn load_bootloader_mappings( &mut self, memory_map: &[MemoryRegion], ) -> Result<(), KernelError>

Load memory mappings from bootloader
