Hello,

Is Hardware-Fuzzing used to spot the "undocumented" chip-features, the CPU which is running below QubesOS?

https://github.com/xoreaxeaxeax/sandsifter/

How harmful can, in security resons, can this extra CPU commands hurt the QubesOS system?

How I can switch off all "unwanted" chip-commands (old commands and not neccessary for QubesOS, undocumented, suspicious, hardware killer-switches), so that QubesOS can use only the harmless CPU-instructions?
