pub struct Vmm<'m, M: PhysMapper, A: FrameAlloc> {
aspace: AddressSpace<'m, M>,
alloc: &'m mut A,
}Expand description
Minimal kernel virtual memory manager.

pub unsafe fn from_current(mapper: &'m M, alloc: &'m mut A) -> Self
§Safety
- Must run at CPL0 with paging enabled.
- Assumes CR3 points at a valid PML4 frame.
Sourcepub fn map_region(
&mut self,
va: VirtualAddress,
pa: PhysicalAddress,
len: u64,
nonleaf: VirtualMemoryPageBits,
leaf: VirtualMemoryPageBits,
) -> Result<(), AddressSpaceMapRegionError>
pub fn map_region( &mut self, va: VirtualAddress, pa: PhysicalAddress, len: u64, nonleaf: VirtualMemoryPageBits, leaf: VirtualMemoryPageBits, ) -> Result<(), AddressSpaceMapRegionError>
§Errors
Allocation fails, e.g. due to OOM.
pub fn unmap_region(&mut self, va: VirtualAddress, len: u64)
pub fn query(&self, va: VirtualAddress) -> Option<PhysicalAddress>
