From 5f4297e865eab5b28c2c17711ecf590934961335 Mon Sep 17 00:00:00 2001 From: Erik Hallnor Date: Tue, 8 Jun 2004 17:31:04 -0400 Subject: [PATCH] Add the capability to read and write memory trace files. Currently is cycle accurate for a single thread FullCPU. --HG-- extra : convert_revision : f8fe545313eb307cc6f5ff2c23894cc9870b1d5b --- cpu/trace/reader/m5_reader.cc | 93 +++++++++++++ cpu/trace/reader/m5_reader.hh | 67 ++++++++++ cpu/trace/reader/mem_trace_reader.cc | 37 ++++++ cpu/trace/reader/mem_trace_reader.hh | 57 ++++++++ cpu/trace/trace_cpu.cc | 192 +++++++++++++++++++++++++++ cpu/trace/trace_cpu.hh | 151 +++++++++++++++++++++ 6 files changed, 597 insertions(+) create mode 100644 cpu/trace/reader/m5_reader.cc create mode 100644 cpu/trace/reader/m5_reader.hh create mode 100644 cpu/trace/reader/mem_trace_reader.cc create mode 100644 cpu/trace/reader/mem_trace_reader.hh create mode 100644 cpu/trace/trace_cpu.cc create mode 100644 cpu/trace/trace_cpu.hh diff --git a/cpu/trace/reader/m5_reader.cc b/cpu/trace/reader/m5_reader.cc new file mode 100644 index 000000000..d6ec7be50 --- /dev/null +++ b/cpu/trace/reader/m5_reader.cc @@ -0,0 +1,93 @@ +/* + * Copyright (c) 2003-2004 The Regents of The University of Michigan + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are + * met: redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer; + * redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution; + * neither the name of the copyright holders nor the names of its + * contributors may be used to endorse or promote products derived from + * this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS + * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT + * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR + * A PARTICULAR PURPOSE ARE DISCLAIMED.
