Constructor & Destructor Documentation

◆ 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.

Member Data Documentation

◆ confTableReported

bool gem5::memory::BackingStoreEntry::confTableReported

Whether this memory should be reported to the configuration table.

Definition at line 94 of file physical.hh.

◆ inAddrMap

bool gem5::memory::BackingStoreEntry::inAddrMap

Whether this memory should appear in the global address map.

Definition at line 99 of file physical.hh.

◆ kvmMap

bool gem5::memory::BackingStoreEntry::kvmMap

Whether KVM should map this memory into the guest address space during acceleration.

Definition at line 105 of file physical.hh.

◆ 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.

Definition at line 89 of file physical.hh.

◆ range

AddrRange gem5::memory::BackingStoreEntry::range

The address range covered in the guest.

Definition at line 83 of file physical.hh.

◆ 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.

Definition at line 111 of file physical.hh.

◆ 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.
