correction: findCptDir is in Simulation.py!

Hi Fulya,
Thanks for your reply. When you use the --at-instruction option on the
command line, gem5 will consider the restore point as the instruction
number. However, using the --checkpoint-restore=1 is not working
either! There is a bug in the function findCptDir in se.py, which
should be fixed (previously, there wasn't any problem using this option).
Cheers

Hi Negar,
If I am not wrong, --checkpoint-restore does not take the instruction
number as a parameter. If you have only 1 checkpoint in your
checkpoint directory which you restore from, you should have
--checkpoint-restore=1. With your current command, it may be
searching for the 2200000000th checkpoint in that directory.
Best,
Fulya

Hi,
I updated the gem5 on my machine after 2 months! I'm trying to
put a checkpoint at a particular instruction number, and then
restoring from that checkpoint, but I received an error! I could
run the same command before updating gem5. Here is the commands
and the error. Did I miss any other options on the command line?
checkpoint:
build/ARM/gem5.fast 0 -d
system/disks/CPU2000/output/bzip2_source/ configs/example/se.py
--bench bzip2_source
--checkpoint-dir=system/disks/CPU2000/output/bzip2_source/
--max-checkpoints=1 --at-instruction --take-checkpoints 2200000000
restore:
build/ARM/gem5.fast -d system/disks/CPU2000/output/bzip2_source/
configs/example/se.py --bench bzip2_source
--checkpoint-dir=system/disks/CPU2000/output/bzip2_source/
--at-instruction --checkpoint-restore=2200000000
