I looked at Exynos Pseudo Random Nubmer Generator driver
(drivers/char/hw_random/exynos-rng.c) and noticed that it always seeds
the device with jiffies. Then I looked at few other drivers and found
that they do not seed themself (or at least I couldn't find this).
I think the hw_random API does not provide generic infrastructure for
What is the preferred approach for seeding a PRNG device? Use jiffies or
a fixed value?
Or maybe the interface should be abandoned in favor of crypto API?
