I'm currently doing some research on defending against Spectre. I'd like to reproduce the results of InvisiSpec. I'm new to gem5. Sorry for asking you about using the experiment environment.
I saw in the example script run_spec_from_ckpt.sh that you use --checkpoint-restore=10000000000. Does this mean the skip the first 10 billion instructions; then, we simulate 1 billion instructions in the paper? And if I use --take-checkpoints=10000000000 to take a checkpoint running the unsafe baseline processor, can I use this checkpoint to run on other processors like IS-Sp?

Yes, you can use different configurations IS-Sp/Fu-Sp etc on the same checkpoints.
You can generate a checkpoint using "--take-checkpoints=N --at-instruction" if you want to skip the first N instructions. Please consult complete commands you should use from the gem5 mannual website.
Then you can do detailed simulation using "--checkpoint-restore=N --at-instruction --maxinsts=M" if you want to do detailed simulation for M instructions.
Hope it helps.
Thanks. I'm now using AtomicSimpleCPU to make a checkpoint.
I think it's also needed to set the ruby cache parameters, I think the configuration in the paper is:
