Member Function Documentation

◆ enqueuePacket()

void gem5::memory::qos::LrgQueuePolicy::enqueuePacket ( PacketPtr pkt )

overridevirtual

This method is called by the memory controller after it enqueues a packet.

It is a way for the queue policy to hook into the packet enqueuing and update relevant metadata. This will then be used once the QueuePolicy::selectPacket will be called.
