Implementations§
source§impl CommonPageResource
impl CommonPageResource
pub fn new( contiguous: bool, growable: bool, vm_map: &'static dyn VMMap, ) -> CommonPageResource
sourcepub fn grow_discontiguous_space(
&self,
space_descriptor: SpaceDescriptor,
chunks: usize,
freelist: Option<&mut dyn FreeList>,
) -> Address
pub fn grow_discontiguous_space( &self, space_descriptor: SpaceDescriptor, chunks: usize, freelist: Option<&mut dyn FreeList>, ) -> Address
Extend the virtual memory associated with a particular discontiguous space. This simply involves requesting a suitable number of chunks from the pool of chunks available to discontiguous spaces.
If the concrete page resource is using a FreeList
, it should pass it
via freelist
, or None
if not using FreeList
.
sourcepub fn release_discontiguous_chunks(&self, chunk: Address)
pub fn release_discontiguous_chunks(&self, chunk: Address)
Release one or more contiguous chunks associated with a discontiguous space.
pub fn release_all_chunks(&self)
pub fn get_head_discontiguous_region(&self) -> Address
