Hi,
I want to run some Android benchmarks (0xbench) in full system mode. I put the
APK file under /system/app directory in the Gingerbread disk image and was able
to launch the app with atomic CPU and without cache. I didn't do any trick as
bbench did to terminate the simulator automatically because I don't think I can
run these benchmarks to completion.
Basically, I want to take a checkpoint right after OS is booted using atomic
mode without caches, and then restore the checkpoint but run the benchmark
using arm_detailed cpu with caches. I find I can restore from the checkpoint
with OS booted but it seems that the benchmark is not launched (but the number
of instructions is advancing). I tried to restore the checkpoint using atomic
cpu mode and it works. I was wondering whether I can take checkpoint in atomic
mode without cache and restore checkpoint in another cpu mode with cache?
The following is the .rcS file I'm using:
run_zeroxbench_test() {
am start -a android.intent.action.MAIN -n
org.zeroxlab.zeroxbenchmark/org.zeroxlab.zeroxbenchmark.TesterJavascript
return
}
sleep 10
/sbin/m5 checkpoint
/sbin/m5 dumpstats
/sbin/m5 resetstats
run_zeroxbench_test
This is the command line that I used to take checkpoint:
build/ARM/gem5.opt --outdir=sunspider_stats2/ configs/example/fs.py -b
sunspider --kernel="vmlinux.smp.mouse.arm" --frame-capture
--checkpoint-dir="sunspider_checkpoint"
I terminate the simulator manually after the benchmark began to run.
This is the command line that I restored the checkpoint:
build/ARM/gem5.opt --outdir=sunspider_stats2/ configs/example/fs.py -b
sunspider -r 1 --kernel="vmlinux.smp.mouse.arm" --frame-capture
--checkpoint-dir="sunspider_checkpoint" --caches --cpu-type=arm_detailed
--l1d_size="32kB" --cacheline_size=64 --l1d_assoc=4 --l1i_size="32kB"
--l1i_assoc=4 --l2cache --l2_size="512kB" --l2_assoc=8 --maxinsts=2000000000
Best regards
Fangfei
