Hi,
I'm working on something else right now, and I might not have a chance to
dig into this for a while, so I figured I would post to the list:
I just updated to the most recent repo, and ALPHA checkpoint restore into
timing-enabled CPUs doesn't appear to be working:
1) Checkpoint by running this and use m5 utility to checkpoint from
command line:
% ./build/ALPHA_FS/m5.debug configs/example/fs.py --num-cpus=4
2) Try to restore from checkpoint:
% ./build/ALPHA_FS/m5.debug --outdir=$OUTDIR configs/example/fs.py
--timing --caches --l2cache --num-cpus=4 -r 1
OR:
% ./build/ALPHA_FS/m5.debug --outdir=$OUTDIR configs/example/fs.py
--detailed --caches --l2cache --num-cpus=4 -r 1
