Sorry for my absence, quite a bit happened to me in real life, but I'm
back with another entropy patch (hopefully ready to finally see a
version make it into CVS). This patch properly implements quality
control, and quality improvement, as well as cleaned up source. The
driver itself can be used wi

After a caffine driven inspired hacking fest I managed to add quality
control to the driver, and resolved the GCS issues, as well as the ones
Marcus noted. I also cleaned up the code, and tweaked it some more.
Any comments would be appericated.

That's not true. Intel introduced hardware random number generators in
their chipsets like ten y

I was going to suggest uppercase for automake conditionals, but you
can refer to prior art, so nevermind :)

This includes a little more sanity checking, and it also fixes the
ring code bug which antrik explained to me in detail. It also has the
patch in the proper format:

? Makefile.in
? aclocal.m4
? autom4te.cache
? build
? build-aux
? conf
After bit bashing, I managed to get the entropy driver working
properly with I/O sources without destroying I/O performance. I also
cleaned up my code somewhat. If you want to use the entropy driver
now, you can use streamio (I'm working on a random translator at the
moment) with settrans -
