The TPM has a hardware random number generator that could be used as a source of entropy in rng-tools.

  • Which device? /dev/tpm0, /dev/tpm1, /dev/tpm2... ?? It requires configuration anyway.

     
  • currently it is /dev/tpm0, If /dev/tmp0 fails we dont use the tpm. There is no configuration required.

     
  • I think you've just made my point clear: it needs configuration.

    How many systems have you seen with multiple TPMs present? Personally, I've seen none.

     
  • why do we still not have this cool functionality? Many systems ship with a TPM with a good fast RNG. These systems run out of entropy completely needlessly today.

    I agree, we need accelerated crypto
