From bf90e1dbde78906b2d2831c123166ce19cf0ec53 Mon Sep 17 00:00:00 2001 From: Kevin Lim Date: Fri, 21 Jul 2006 15:46:12 -0400 Subject: Minor functionality updates. SConstruct: Include an option to specify the CPUs being tested. src/cpu/SConscript: Checker isn't SMT right now, so don't do SMT tests with the O3CPU if we're using the checker. src/python/m5/objects/O3CPU.py: Include default options. Unfortunately FullO3Config.py is still needed because it specifies which FUPool is being used. tests/SConscript: Several minor updates (sorry for one commit). Updated the copyright and fixed some m5 style issues. Also added the ability to specify which CPUs to run the tests on. --HG-- extra : convert_revision : b0b801115705544ea02e572e31314f7bb8b5f0f2 --- src/python/m5/objects/O3CPU.py | 144 ++++++++++++++++++++++------------------- 1 file changed, 77 insertions(+), 67 deletions(-) (limited to 'src/python') diff --git a/src/python/m5/objects/O3CPU.py b/src/python/m5/objects/O3CPU.py index d6bc454ad..41208929a 100644 --- a/src/python/m5/objects/O3CPU.py +++ b/src/python/m5/objects/O3CPU.py @@ -1,91 +1,101 @@ from m5 import build_env from m5.config import * from BaseCPU import BaseCPU +from Checker import O3Checker class DerivO3CPU(BaseCPU): type = 'DerivO3CPU' -
