From 35147170f91ccbc73d3e75440a5301f758e54dfc Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Sun, 27 May 2007 19:21:17 -0700 Subject: Move SimObject python files alongside the C++ and fix the SConscript files so that only the objects that are actually available in a given build are compiled in. Remove a bunch of files that aren't used anymore. --HG-- rename : src/python/m5/objects/AlphaTLB.py => src/arch/alpha/AlphaTLB.py rename : src/python/m5/objects/SparcTLB.py => src/arch/sparc/SparcTLB.py rename : src/python/m5/objects/BaseCPU.py => src/cpu/BaseCPU.py rename : src/python/m5/objects/FuncUnit.py => src/cpu/FuncUnit.py rename : src/python/m5/objects/IntrControl.py => src/cpu/IntrControl.py rename : src/python/m5/objects/MemTest.py => src/cpu/memtest/MemTest.py rename : src/python/m5/objects/FUPool.py => src/cpu/o3/FUPool.py rename : src/python/m5/objects/FuncUnitConfig.py => src/cpu/o3/FuncUnitConfig.py rename : src/python/m5/objects/O3CPU.py => src/cpu/o3/O3CPU.py rename : src/python/m5/objects/OzoneCPU.py => src/cpu/ozone/OzoneCPU.py rename : src/python/m5/objects/SimpleOzoneCPU.py => src/cpu/ozone/SimpleOzoneCPU.py rename : src/python/m5/objects/BadDevice.py => src/dev/BadDevice.py rename : src/python/m5/objects/Device.py => src/dev/Device.py rename : src/python/m5/objects/DiskImage.py => src/dev/DiskImage.py rename : src/python/m5/objects/Ethernet.py => src/dev/Ethernet.py rename : src/python/m5/objects/Ide.py => src/dev/Ide.py rename : src/python/m5/objects/Pci.py => src/dev/Pci.py rename : src/python/m5/objects/Platform.py => src/dev/Platform.py rename : src/python/m5/objects/SimConsole.py => src/dev/SimConsole.py rename : src/python/m5/objects/SimpleDisk.py => src/dev/SimpleDisk.py rename : src/python/m5/objects/Uart.py => src/dev/Uart.py rename : src/python/m5/objects/AlphaConsole.py => src/dev/alpha/AlphaConsole.py rename : src/python/m5/objects/Tsunami.py => src/dev/alpha/Tsunami.py rename : src/python/m5/objects/T1000.py => src/dev/sparc/T1000.py rename : src/python/m5/objects/Bridge.py => src/mem/Bridge.py rename : src/python/m5/objects/Bus.py => src/mem/Bus.py rename : src/python/m5/objects/MemObject.py => src/mem/MemObject.py rename : src/python/m5/objects/PhysicalMemory.py => src/mem/PhysicalMemory.py rename : src/python/m5/objects/BaseCache.py => src/mem/cache/BaseCache.py rename : src/python/m5/objects/CoherenceProtocol.py => src/mem/cache/coherence/CoherenceProtocol.py rename : src/python/m5/objects/Repl.py => src/mem/cache/tags/Repl.py rename : src/python/m5/objects/Process.py => src/sim/Process.py rename : src/python/m5/objects/Root.py => src/sim/Root.py rename : src/python/m5/objects/System.py => src/sim/System.py extra : convert_revision : 173f8764bafa8ef899198438fa5573874e407321 --- src/mem/cache/BaseCache.py | 91 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 91 insertions(+) create mode 100644 src/mem/cache/BaseCache.py (limited to 'src/mem/cache/BaseCache.py') diff --git a/src/mem/cache/BaseCache.py b/src/mem/cache/BaseCache.py new file mode 100644 index 000000000..4b98f6b30 --- /dev/null +++ b/src/mem/cache/BaseCache.py @@ -0,0 +1,91 @@ +# Copyright (c) 2005-2007 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.
