Struct VmHeap

pub struct VmHeap {
    zones: [Vec<Arc<UmaZone>>; 63],
    stats: CpuLocal<RefCell<Stats>>,
}

Kernel heap that allocate a memory from a virtual memory management system. This struct is a merge of malloc_type and malloc_type_internal structure.

Fields

zones: [Vec<Arc<UmaZone>>; 63]

stats: CpuLocal<RefCell<Stats>>

Implementations

impl VmHeap

const KMEM_ZSHIFT: usize = 4usize

const KMEM_ZBASE: usize = 16usize

const KMEM_ZMASK: usize = 15usize

const KMEM_ZSIZE: usize = 256usize

pub fn new() -> Self

See kmeminit on the Orbis for a reference.

Reference offsets

Version	Offset
PS4 11.00	0x1A4B80

pub unsafe fn alloc(&self, layout: Layout) -> *mut u8

Returns null on failure.

See malloc on the Orbis for a reference.

Safety

layout must be nonzero.

pub unsafe fn dealloc(&self, _: *mut u8, _: Layout)

Safety

ptr must be obtained with Self::alloc() and layout must be the same one that was passed to that method.
