Here is a small patch for 2.6.11 that adds a routine:

add_true_randomness(__u32 *buf, int nwords);

It neither applies correctly nor compiles in current kernels. 2.6.11 is
very old in kernel time.

Are we likely to see any in-kernel users of this?


I added similar support to the pre hw_random AMD8111 driver
a long time ago. Basically a timer that regularly read some
dat from the hw random generator and feed it into the random
code.

I think it is a good idea, because it doesnt make much sense
imho to run a daemon for something that can be done in 20 lines
of code in the kernel.

Check your kernel history.

We -used- to need data from RNG directly into the kernel randomness pool. The consensus was that the FIPS testing should be moved to userspace.
