Detailed Description

This is the master port of the communication monitor.

All recv functions call a function in CommMonitor, where the send function of the slave port is called. Besides this, these functions can also perform actions for capturing statistics.

Member Function Documentation

bool CommMonitor::MonitorMasterPort::isSnooping ( ) const

inlineprotectedvirtual

Determine if this master port is snooping or not.

The default implementation returns false and thus tells the neighbour we are not snooping. Any master 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 MasterPort.

Definition at line 164 of file comm_monitor.hh.

Tick CommMonitor::MonitorMasterPort::recvAtomicSnoop ( PacketPtr pkt )

inlineprotectedvirtual

Receive an atomic snoop request packet from the slave port.

Reimplemented from MasterPort.

Definition at line 144 of file comm_monitor.hh.

References mon, and CommMonitor::recvAtomicSnoop().

void CommMonitor::MonitorMasterPort::recvFunctionalSnoop ( PacketPtr pkt )

inlineprotectedvirtual

Receive a functional snoop request packet from the slave port.

Reimplemented from MasterPort.

Definition at line 139 of file comm_monitor.hh.

References mon, and CommMonitor::recvFunctionalSnoop().

void CommMonitor::MonitorMasterPort::recvRangeChange ( )

inlineprotectedvirtual

Called to receive an address range change from the peer slave 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 MasterPort.

Definition at line 159 of file comm_monitor.hh.

References mon, and CommMonitor::recvRangeChange().

void CommMonitor::MonitorMasterPort::recvReqRetry ( )

inlineprotectedvirtual

Called by the slave port if sendTimingReq was called on this master port (causing recvTimingReq to be called on the slave port) and was unsuccesful.

Implements MasterPort.

Definition at line 169 of file comm_monitor.hh.

References mon, and CommMonitor::recvReqRetry().

void CommMonitor::MonitorMasterPort::recvRetrySnoopResp ( )

inlineprotectedvirtual

Called by the slave port if sendTimingSnoopResp was called on this master port (causing recvTimingSnoopResp to be called on the slave port) and was unsuccesful.

Reimplemented from MasterPort.

Definition at line 174 of file comm_monitor.hh.

bool CommMonitor::MonitorMasterPort::recvTimingResp ( PacketPtr pkt )

inlineprotectedvirtual

Receive a timing response from the slave port.

Implements MasterPort.

void CommMonitor::MonitorMasterPort::recvTimingSnoopReq ( PacketPtr pkt )

inlineprotectedvirtual

Receive a timing snoop request from the slave port.
