Implementations

impl<P> AddressSpace<P>

where P: Platform,

pub fn new<A>( owner: KernelObjectId, kernel_page_table: &P::PageTable, allocator: &A, ) -> Arc<AddressSpace<P>>

where A: FrameAllocator<P::PageTableSize>,

pub fn map_memory_object( &self, memory_object: Arc<MemoryObject>, virtual_address: VAddr, allocator: &Pmm, ) -> Result<(), MapMemoryObjectError>

pub fn alloc_task_slot( &self, initial_stack_size: usize, allocator: &Pmm, ) -> Option<TaskSlot>

Try to allocate a slot for a Task. Creates a user stack with initial_stack_size bytes initially allocated. Returs None if no more tasks can be created in this Address Space.
