Source: linux Severity: normal Dear Maintainer,
Installing bullseye or bookworm on a Pine64 [0] results in a system with very low entropy. After some light usage over the serial console I see: ``` cat /proc/sys/kernel/random/entropy_avail 3 ``` This device has a hardware RNG which could be used with rng-tools [1] to increase entropy but the kernel configuration has it disabled. Could the `CRYPTO_DEV_SUN8I_CE_PRNG` option be enabled? Then all users of the A64 SOC could have access to more entropy. A practical imediate impact is that boot times will decrease for users of systemd since the systemd-random-seed.service [2] will be able to gather entropy much faster. Currently on a Pine64 `systemd-analyze blame` shows the random seed service taking 3 seconds on boot.
