Adding the “–vm” argument gives (and still does not work):

Reloading the rapl kernel modules, and restarting the machine does not seem to change anything.
To Reproduce
cargo build
./target/debug/scaphandre stdout

Something should happen 😃

Hi @bpetit, you are too fast 😄 I was too quick and pulled the wrong branch, it seems to work on first observation! Will do a more thorough evaluation next week. Thanks so much! If I can do any specific tests for you please let me know.
Sure! Can you send me an email/DM, and I can work out how to get you ssh access to a machine.
