Gustavo, All,

There was a talk at LinuxCon 2012 (last year) in Barcelonna, by H Peter
Anvin, titled "Don't play dice with random numbers", where he said he
was very skeptic about HAVEGE:
    https://lwn.net/Articles/525459/

Quote:
    Most of the papers that he has read run along the lines, "we took the
    output from HAVEGE, and ran some tests on it and all of the tests passed".

    One of Peter's colleagues replaced the random input source employed
    by HAVEGE with a constant stream of ones. All of the same tests passed.

    So, while I can't really recommend it, I can't not recommend it either.

Thought I would mention it.

Regards,
Yann E. MORIN.
