From 9bc132e4738c53be2dd9c2fdf5e4dd8e73d8970b Mon Sep 17 00:00:00 2001 From: Nilay Vaish Date: Thu, 24 Jan 2013 12:29:00 -0600 Subject: regressions: update stats due to branch predictor changes The actual statistical values are being updated for only two tests belonging to sparc architecture and inorder cpu: 00.hello and 02.insttest. For others the patch updates config.ini and name changes to statistical variables. --- .../se/30.eon/ref/arm/linux/o3-timing/config.ini | 37 ++++++++++++---------- .../long/se/30.eon/ref/arm/linux/o3-timing/simout | 10 +++--- .../se/30.eon/ref/arm/linux/o3-timing/stats.txt | 27 ++++++++-------- 3 files changed, 41 insertions(+), 33 deletions(-) (limited to 'tests/long/se/30.eon/ref/arm/linux/o3-timing') diff --git a/tests/long/se/30.eon/ref/arm/linux/o3-timing/config.ini b/tests/long/se/30.eon/ref/arm/linux/o3-timing/config.ini index cd1ce8718..4cd0f21e4 100644 --- a/tests/long/se/30.eon/ref/arm/linux/o3-timing/config.ini +++ b/tests/long/se/30.eon/ref/arm/linux/o3-timing/config.ini @@ -31,22 +31,18 @@ system_port=system.membus.slave[0] [system.cpu] type=DerivO3CPU -children=dcache dtb fuPool icache interrupts isa itb l2cache toL2Bus tracer workload -BTBEntries=4096 -BTBTagSize=16 +children=branchPred dcache dtb fuPool icache interrupts isa itb l2cache toL2Bus tracer workload LFSTSize=1024 LQEntries=32 LSQCheckLoads=true LSQDepCheckShift=4 -RASSize=16 SQEntries=32 SSITSize=1024 activity=0 backComSize=5 +branchPred=system.cpu.branchPred cachePorts=200 checker=Null -choiceCtrBits=2 -choicePredictorSize=8192 clock=500 commitToDecodeDelay=1 commitToFetchDelay=1 @@ -69,23 +65,15 @@ forwardComSize=5 fuPool=system.cpu.fuPool function_trace=false function_trace_start=0 -globalCtrBits=2 -globalHistoryBits=13 -globalPredictorSize=8192 iewToCommitDelay=1 iewToDecodeDelay=1 iewToFetchDelay=1 iewToRenameDelay=1 -instShiftAmt=2 interrupts=system.cpu.interrupts isa=system.cpu.isa issueToExecuteDelay=1 issueWidth=8 itb=system.cpu.itb -localCtrBits=2 -localHistoryBits=11 -localHistoryTableSize=2048 -localPredictorSize=2048 max_insts_all_threads=0 max_insts_any_thread=0 max_loads_all_threads=0 @@ -97,7 +85,6 @@ numPhysIntRegs=256 numROBEntries=192 numRobs=1 numThreads=1 -predType=tournament profile=0 progress_interval=0 renameToDecodeDelay=1 @@ -126,6 +113,24 @@ workload=system.cpu.workload dcache_port=system.cpu.dcache.cpu_side icache_port=system.cpu.icache.cpu_side +[system.cpu.branchPred] +type=BranchPredictor +BTBEntries=4096 +BTBTagSize=16 +RASSize=16 +choiceCtrBits=2 +choicePredictorSize=8192 +globalCtrBits=2 +globalHistoryBits=13 +globalPredictorSize=8192 +instShiftAmt=2 +localCtrBits=2 +localHistoryBits=11 +localHistoryTableSize=2048 +localPredictorSize=2048 +numThreads=1 +predType=tournament + [system.cpu.dcache] type=BaseCache addr_ranges=0:18446744073709551615 @@ -522,7 +527,7 @@ egid=100 env= errout=cerr euid=100 -executable=/gem5/dist/cpu2000/binaries/arm/linux/eon +executable=/scratch/nilay/GEM5/dist/m5/cpu2000/binaries/arm/linux/eon gid=100 input=cin max_stack_size=67108864 diff --git a/tests/long/se/30.eon/ref/arm/linux/o3-timing/simout b/tests/long/se/30.eon/ref/arm/linux/o3-timing/simout index 46ca25e4c..6de8db104 100755 --- a/tests/long/se/30.eon/ref/arm/linux/o3-timing/simout +++ b/tests/long/se/30.eon/ref/arm/linux/o3-timing/simout @@ -1,9 +1,11 @@ +Redirecting stdout to build/ARM/tests/opt/long/se/30.eon/arm/linux/o3-timing/simout +Redirecting stderr to build/ARM/tests/opt/long/se/30.eon/arm/linux/o3-timing/simerr gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. -gem5 compiled Jan 4 2013 21:17:24 -gem5 started Jan 5 2013 00:06:54 -gem5 executing on u200540 +gem5 compiled Jan 23 2013 19:43:25 +gem5 started Jan 23 2013 20:14:28 +gem5 executing on ribera.cs.wisc.edu command line: build/ARM/gem5.opt -d build/ARM/tests/opt/long/se/30.eon/arm/linux/o3-timing -re tests/run.py build/ARM/tests/opt/long/se/30.eon/arm/linux/o3-timing Global frequency set at 1000000000000 ticks per second info: Entering event queue @ 0.
