Well, there isn't any :o) That's why there's a user-level implementation for such a beast for those who do need it.

Some guy contacted me about audio-entropyd and told me he'd done a lot of analysis on all how this and gave me a few hints how to improve the quality of what is produced with this tool. A quick fourier- transformation doesn't really show any peaks. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
