Perhaps you could read more carefully -- maybe my question was
too well hidden? Anyway, is there a way to specify on Linux
which IRQs are used stir the entropy pool?
The above-listed example shows how FreeBSD allows the syadmin to
specify which ones are deemed to provide sufficient entropy -- it's
not a mask, and it happens to be conveniently located in the startup
script, not source code.
