Hi Joel,
Many thanks for the patch. However I'm not able to test it until Monday,
I hope it solves the problem.
Cheers

Hi guys,
Attached is a patch to side-step the max tick setting, which should
get you running again. To apply it:
% cd <gem5_directory>
% hg qimport <path_to>/minor_fix_for_maxticks
% hg qpush
Then rebuild
@Nithesh: I'm not able to replicate the fast-forwarding bug that
you're experiencing, but skimming through the code that was changed in
changeset 9816, it doesn't look like that would have caused the problem.

Hi Joel
Thanks for your prompt reply and attention towards the problem. Is
the Fast forward problem also because of the same change?
Regards

Hey Negar and Nithesh,
It looks like this is related to the change I made a couple
weeks ago to add support for specifying maximum simulation
ticks (changeset 9816:971507cbbe65
http://repo.gem5.org/gem5/rev/971507cbbe65). I have an idea
for a temporary quick-fix for you, and I'll try to get it to
you this afternoon. If you don't want to wait for a fix, you
could consider rolling your repo back to changeset
9815:3b3b94536547:
% hg update -r 9815
Then rebuild.
Sorry for any inconvenience,
Joel

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/
