Member Function Documentation

◆ isSnooping()

bool gem5::MemDelay::RequestPort::isSnooping ( ) const

inlineoverrideprotectedvirtual

Determine if this request port is snooping or not.

The default implementation returns false and thus tells the neighbour we are not snooping. Any request port that wants to receive snoop requests (e.g. a cache connected to a bus) has to override this function.

Returns: true if the port should be considered a snooper

Reimplemented from gem5::RequestPort.

◆ recvAtomicSnoop()

Tick gem5::MemDelay::RequestPort::recvAtomicSnoop ( PacketPtr pkt )

overrideprotectedvirtual

Receive an atomic snoop request packet from our peer.

Implements gem5::AtomicRequestProtocol.

Definition at line 115 of file mem_delay.cc.

◆ recvFunctionalSnoop()

void gem5::MemDelay::RequestPort::recvFunctionalSnoop ( PacketPtr pkt )

overrideprotectedvirtual

Receive a functional snoop request packet from the peer.

Implements gem5::FunctionalRequestProtocol.

Definition at line 105 of file mem_delay.cc.

References gem5::Packet::makeResponse().

◆ recvRangeChange()

void gem5::MemDelay::RequestPort::recvRangeChange ( )

inlineoverrideprotectedvirtual

Called to receive an address range change from the peer response port.

The default implementation ignores the change and does nothing. Override this function in a derived class if the owner needs to be aware of the address ranges, e.g. in an interconnect component like a bus.

Reimplemented from gem5::RequestPort.
