pub struct PhysAllocator {
    segs: Vec<PhysSeg>,
    nfree: usize,
    lookup_lists: [Arc<Mutex<[[[IndexSet<Arc<VmPage>, FxBuildHasher>; 13]; 3]; 2]>>; 2],
}

Provides methods to allocate physical memory.

Fields

segs: Vec<PhysSeg>

nfree: usize

lookup_lists: [Arc<Mutex<[[[IndexSet<Arc<VmPage>, FxBuildHasher>; 13]; 3]; 2]>>; 2]

Implementations

impl PhysAllocator

pub fn new(phys_avail: &[usize; 61], ma: Option<&MemAffinity>) -> Self

See vm_phys_init on the Orbis for a reference.

pub fn segment(&self, i: usize) -> &PhysSeg

Panics

If i is not valid.

pub fn segment_index(&self, pa: usize) -> Option<usize>

See vm_phys_paddr_to_segind on the Orbis for a reference. Our implementation is a bit differences here. Orbis will panic if segment not found but we return None instead.
