From 1d403960afec613f3aa9f1fc2ffc3287139e1d86 Mon Sep 17 00:00:00 2001 From: Geoffrey Blake Date: Thu, 19 Mar 2015 04:06:10 -0400 Subject: mem: Enable CommMonitor to output traces in atomic mode The CommMonitor by default only allows memory traces to be gathered in timing mode. This patch allows memory traces to be gathered in atomic mode if all one needs is a functional trace of memory addresses used and timing information is of a secondary concern. --- src/mem/comm_monitor.cc | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) (limited to 'src/mem') diff --git a/src/mem/comm_monitor.cc b/src/mem/comm_monitor.cc index dc4fa4bd4..a0f8688f2 100644 --- a/src/mem/comm_monitor.cc +++ b/src/mem/comm_monitor.cc @@ -1,5 +1,5 @@ /* - * Copyright (c) 2012-2013 ARM Limited + * Copyright (c) 2012-2013, 2015 ARM Limited * All rights reserved * * The license below extends only to copyright in the software and shall @@ -176,10 +176,23 @@ CommMonitor::recvFunctionalSnoop(PacketPtr pkt) Tick CommMonitor::recvAtomic(PacketPtr pkt) { - // allow stack distance calculations for atomic if enabled + // do stack distance calculations if enabled if (stackDistCalc) stackDistCalc->update(pkt->cmd, pkt->getAddr()); + // if tracing enabled, store the packet information + // to the trace stream + if (traceStream != NULL) { + ProtoMessage::Packet pkt_msg; + pkt_msg.set_tick(curTick()); + pkt_msg.set_cmd(pkt->cmdToIndex()); + pkt_msg.set_flags(pkt->req->getFlags()); + pkt_msg.set_addr(pkt->getAddr()); + pkt_msg.set_size(pkt->getSize()); + + traceStream->write(pkt_msg); + } + return masterPort.sendAtomic(pkt); } -- cgit v1.2.3
