build/X86/gem5.opt --some-option configs/examples/fs.py

boot with the more detailed and slow HPI CPU model:

./run --arch arm --emulator gem5 -- --caches --cpu-type=HPI

To pass options to the gem5 executable we expose the --gem5-exe-args option:

get help:

./run --gem5-exe-args='-h' --emulator gem5
