How to correctly use a hardware random number generator (hwrng, trng) on Linux 5+ (Debian 12+)

How to correctly use a hardware random number generator (hwrng, trng) on Linux 5+ (Debian 12+)

Problem

  1. Linux entropy pool doesn't know about external, non-default, non-driver entropy sources.
  2. Modern Linux usually reports 256 for cat /proc/sys/kernel/random/entropy_avail. This has to do with the entropy pool rewrite sometime ago that prevented blocking of /dev/random.
  3. There is presently no userland entropy pool seeding "pull" mechanism.

Solution
