Public Attributes
AddrRange	range
	The address range covered in the guest.
uint8_t *	pmem
	Pointer to the host memory this range maps to.
bool	confTableReported
	Whether this memory should be reported to the configuration table.
bool	inAddrMap
	Whether this memory should appear in the global address map.
bool	kvmMap
	Whether KVM should map this memory into the guest address space during acceleration.
int	shmFd
	If this backing store is based on a shared memory, this is the fd to the shared memory.
off_t	shmOffset
	If this backing store is based on a shared memory, this is the offset of this backing store in the share memory.

BackingStoreEntry()

gem5::memory::BackingStoreEntry::BackingStoreEntry ( AddrRange range, uint8_t * pmem, bool conf_table_reported, bool in_addr_map, bool kvm_map, int shm_fd = -1, off_t shm_offset = 0 )

inline

Create a backing store entry.

Don't worry about managing the memory pointers, because PhysicalMemory is responsible for that.

pmem

uint8_t* gem5::memory::BackingStoreEntry::pmem

Pointer to the host memory this range maps to.

This memory is the same size as the range field.

range

AddrRange gem5::memory::BackingStoreEntry::range

The address range covered in the guest.

shmFd

int gem5::memory::BackingStoreEntry::shmFd

If this backing store is based on a shared memory, this is the fd to the shared memory.

Otherwise, it should be -1.

shmOffset

off_t gem5::memory::BackingStoreEntry::shmOffset

If this backing store is based on a shared memory, this is the offset of this backing store in the share memory.

Otherwise, the value is 0.
