Subject: /dev/random on PPC40EXr

Message-ID: <22824979.post@talk.nabble.com> (raw)
Hi,
On my custom board based on 405EXr /dev/random produces no output
at all, and /dev/urandom is not random enough for our purposes. Saving
entropy pool between reboots doesn't help much.
What can be done to increase the entropy of the system ?
I was thinking of adding IRQF_SAMPLE_RANDOM to network driver,
but since not too many drivers implement it, I don't know whether
it's a good idea or not.
Is there any work in progress to develop hw_random driver for 4xx
TRNG ?
Thanks a lot.
Felix.
