Maps a virtual memory region to a physical memory region.

Parameters

vaddr	The starting virtual address of the region.
paddr	The starting physical address where the region is mapped.
size	The length of the region.
flags	Generic mapping flags that can be set by or-ing values from MappingFlags enum.

◆ serialize()

template<class ... EntryTypes>

void MultiLevelPageTable< EntryTypes >::serialize ( CheckpointOut & cp ) const

inlineoverridevirtual

Serialize an object.

Output an object's state into the current checkpoint section.

Parameters

cp	Checkpoint state

Since, the page table is stored in system memory which is serialized separately, we will serialize just the base pointer

Implements Serializable.

◆ unserialize()

template<class ... EntryTypes>

void MultiLevelPageTable< EntryTypes >::unserialize ( CheckpointIn & cp )

Unserialize an object.

Read an object's state from the current checkpoint section.

Parameters

cp	Checkpoint state
