Inheritance diagram for gem5::MSHR::Target:

Public Types
enum	Source { FromCPU , FromSnoop , FromPrefetcher }

Public Member Functions
	Target (PacketPtr _pkt, Tick _readyTime, Counter _order, Source _source, bool _markedPending, bool alloc_on_fill)
Public Member Functions inherited from gem5::QueueEntry::Target
	Target (PacketPtr _pkt, Tick ready_time, Counter _order)
	Default constructor.

Public Attributes
const Source	source
	Request from cpu, memory, or prefetcher?
bool	markedPending
	We use this flag to track whether we have cleared the downstreamPending flag for the MSHR of the cache above where this packet originates from and guard noninitial attempts to clear it.
const bool	allocOnFill
	Should the response servicing this target list allocate in the cache?
Public Attributes inherited from gem5::QueueEntry::Target
const Tick	recvTime
	Time when request was received (for stats)
const Tick	readyTime
	Time when request is ready to be serviced.
const Counter	order
	Global order (for memory consistency mgmt)
PacketPtr	pkt
	Pending request packet.

allocOnFill

const bool gem5::MSHR::Target::allocOnFill

markedPending

bool gem5::MSHR::Target::markedPending

We use this flag to track whether we have cleared the downstreamPending flag for the MSHR of the cache above where this packet originates from and guard noninitial attempts to clear it.

The flag markedPending needs to be updated when the TargetList is in service which can be: 1) during the Target instantiation if the MSHR is in service and the target is not deferred, 2) when the MSHR becomes in service if the target is not deferred, 3) or when the TargetList is promoted (deferredTargets -> targets).
