From 88554790c34f6fef4ba6285927fb9742b90ab258 Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Mon, 15 Oct 2012 08:10:54 -0400 Subject: Mem: Use cycles to express cache-related latencies This patch changes the cache-related latencies from an absolute time expressed in Ticks, to a number of cycles that can be scaled with the clock period of the caches. Ultimately this patch serves to enable future work that involves dynamic frequency scaling. As an immediate benefit it also makes it more convenient to specify cache performance without implicitly assuming a specific CPU core operating frequency. The stat blocked_cycles that actually counter in ticks is now updated to count in cycles. As the timing is now rounded to the clock edges of the cache, there are some regressions that change. Plenty of them have very minor changes, whereas some regressions with a short run-time are perturbed quite significantly. A follow-on patch updates all the statistics for the regressions. --- tests/configs/inorder-timing.py | 8 ++++---- tests/configs/memtest.py | 10 +++++----- tests/configs/o3-timing-checker.py | 7 +++++-- tests/configs/o3-timing-mp.py | 12 ++++++------ tests/configs/o3-timing.py | 7 +++++-- tests/configs/pc-o3-timing.py | 18 +++++++++--------- tests/configs/pc-simple-atomic.py | 18 +++++++++--------- tests/configs/pc-simple-timing.py | 18 +++++++++--------- tests/configs/realview-o3-checker.py | 14 +++++++------- tests/configs/realview-o3-dual.py | 18 +++++++++--------- tests/configs/realview-o3.py | 14 +++++++------- tests/configs/realview-simple-atomic-dual.py | 18 +++++++++--------- tests/configs/realview-simple-atomic.py | 14 +++++++------- tests/configs/realview-simple-timing-dual.py | 18 +++++++++--------- tests/configs/realview-simple-timing.py | 14 +++++++------- tests/configs/simple-atomic-mp.py | 12 ++++++------ tests/configs/simple-timing-mp.py | 12 ++++++------ tests/configs/simple-timing.py | 7 ++++--- tests/configs/tsunami-inorder.py | 14 +++++++------- tests/configs/tsunami-o3-dual.py | 18 +++++++++--------- tests/configs/tsunami-o3.py | 14 +++++++------- tests/configs/tsunami-simple-atomic-dual.py | 18 +++++++++--------- tests/configs/tsunami-simple-atomic.py | 14 +++++++------- tests/configs/tsunami-simple-timing-dual.py | 18 +++++++++--------- tests/configs/tsunami-simple-timing.py | 14 +++++++------- 25 files changed, 178 insertions(+), 171 deletions(-) (limited to 'tests/configs') diff --git a/tests/configs/inorder-timing.py b/tests/configs/inorder-timing.py index af7609e9f..5f2156ff9 100644 --- a/tests/configs/inorder-timing.py +++ b/tests/configs/inorder-timing.py @@ -33,8 +33,8 @@ m5.util.addToPath('../configs/common') class MyCache(BaseCache): assoc = 2 block_size = 64 -
