Member Function Documentation

closeStreams()

void MemTraceProbe::closeStreams ( )

protected

Callback to flush and close all open output streams on exit.

If we were calling the destructor it could be done there.

Definition at line 100 of file mem_trace.cc.

References traceStream.

handleRequest()

void MemTraceProbe::handleRequest ( const ProbePoints::PacketInfo &  pkt_info )

overrideprotectedvirtual

Callback to analyse intercepted Packets.

Implements BaseMemProbe.

Definition at line 107 of file mem_trace.cc.

References ProbePoints::PacketInfo::addr, ProbePoints::PacketInfo::cmd, curTick(), ProbePoints::PacketInfo::flags, ProbePoints::PacketInfo::master, MemTraceProbe(), ProbePoints::PacketInfo::pc, ProbePoints::PacketInfo::size, MemCmd::toInt(), traceStream, withPC, and ProtoOutputStream::write().

startup()

void MemTraceProbe::startup ( )

overrideprotectedvirtual

startup() is the final initialization call before simulation.

All state is initialized (including unserialized state, if any, such as the curTick() value), so this is the appropriate place to schedule initial event(s) for objects that need them.

Reimplemented from SimObject.
