Hi,
I don't know what is wrong that the IPC is 0 in detail mode and no
instruction is committed.
The command I used is:
build/X86_SE/m5.opt configs/example/cmp.py --prog-interval=7000000 -F
6000000 --maxinst 50000000 -d --caches --l2cache -b lbm
The output in the fast forward mode looks normal:
Switch at instruction count:6000000
info: Entering event queue @ 0. Starting simulation...
warn: instruction 'fnstcw_Mw' unimplemented
warn: instruction 'fldcw_Mw' unimplemented
MAIN_printInfo:
warn: instruction 'emms' unimplemented
grid size : 100 x 100 x 130 = 1.30 * 10^6 Cells
nTimeSteps : 3000
result file : reference.dat
action : nothing
simulation type: lid-driven cavity
obstacle file : <none>
7000000000: Event_28: system.cpu progress event, total committed:4093433,
progress insts committed: 4093433, IPC: 0.584776
hack: be nice to actually delete the event here
However in the detail simulation the IPC is 0 for 44M instructions. It
means nothing!!
Switched CPUS @ tick 10268402000
Changing memory mode to timing

35000000000: Event_28: system.cpu progress event, total committed:6000000,
progress insts committed: 0, IPC: 0
Exiting @ tick 41246130000 because a thread reached the max instruction
count
Is there any comment or idea to debug more to see what is happening?
Thanks,
