From 9321a41c62c25643d7b6381abbcf5694a012e056 Mon Sep 17 00:00:00 2001 From: Nilay Vaish Date: Sat, 11 Oct 2014 15:02:23 -0500 Subject: ruby: drop Orion network power model Orion is being dropped from ruby. It would be replaced with DSENT which has better models. Note that the power / energy numbers reported after this patch has been applied are not for use. --- src/mem/ruby/network/orion/Clock.cc | 176 ------------------------------------ 1 file changed, 176 deletions(-) delete mode 100644 src/mem/ruby/network/orion/Clock.cc (limited to 'src/mem/ruby/network/orion/Clock.cc') diff --git a/src/mem/ruby/network/orion/Clock.cc b/src/mem/ruby/network/orion/Clock.cc deleted file mode 100644 index fda18cd64..000000000 --- a/src/mem/ruby/network/orion/Clock.cc +++ /dev/null @@ -1,176 +0,0 @@ -/* - * Copyright (c) 2009 Princeton University - * Copyright (c) 2009 The Regents of the University of California - * 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.
