Hi Furat
Thanks now I am getting a results.stat file filled with data. The stats file
has got a large number of entries some of them are multiple occurrences such as
L1 miss rate etc. I am interested in getting data such as number of cycles, L1
D/I cache miss, L2 Cache miss, and on-chip network traffic. Is the stats file
reporting all the results of application+OS kernel or only application? Can you
please advise on getting the above mentioned statistics, I will be extremely
thankful.
Cheers
YQ

Hi
config/default.conf is not a simconfig file. It is used in compilation time to
build the machines. a simple simconfig file looks like this:
-machine ooo_2_th
-stopinsns 100m
-kill-after-run
-stats results.stats
-logfile results.log
Try this:
1- qemu/qemu-system-x86_64 -m 1024 -hda diskimages/splash.img -simconfig
email.cfg
2- wait untill the machine boots
3- in the quest terminal type: ./start_sim;./fibonacci;./stop_sim
4- wait until qemu exits
-Furat
