I looked at it now. It seems to observe some real entropy, but I think
they overestimate the amount. Some of the events they count show up in
some/many counters, and I don't see any attempt to estimate or account
for covariance.
So, yes, good stuff IMHO, but I don't think it's actually hundreds of
megabits per second. Still, even 1kbps of real entropy isn't bad.
I can't imagine it being equivalent to a (non-intel/amd) hardware source
of entropy when it comes to quality of entropy - have there been any
quality analysis performed?
It is a shame IDQ is the only vendor with a PCI-e device, and also the
only vendor it seems that offers something quality and obtainable (I
can't find an open source hardware entropy device that is really for
sale right away
