Struct kernel::memory_management::virtual_space::VirtualSpace

pub struct VirtualSpace<T: ?Sized> {
    size: usize,
    data: NonNull<T>,
}

A wrapper over memory that is defined by its physical address. We map this memory in virtual space, and return a pointer to it.

Fields

size: usize

data: NonNull<T>

Implementations

impl<T> VirtualSpace<T>

pub unsafe fn new(physical_start: u64) -> Result<Self, VirtualSpaceError>

Create a new virtual space for the given physical_start on the given type T.

Safety

• Must be a valid physical address
• The memory must be defined by default. if its not, use new_uninit instead

pub unsafe fn new_uninit( physical_start: u64 ) -> Result<VirtualSpace<MaybeUninit<T>>, VirtualSpaceError>

Create a new virtual space for the given physical_start on the given type T. But will assume that the memory is not initialized, and will return a MaybeUninit pointer.

Safety

• Must be a valid physical address

pub unsafe fn new_slice( physical_start: u64, len: usize ) -> Result<VirtualSpace<[T]>, VirtualSpaceError>

Create a new virtual space for the given physical_start on the given slice type [T].

Safety

• Must be a valid physical address
• The memory must be defined by default. currently, there is no way to create a slice of MaybeUninit
