There was some discussion of /dev/random on an ipsec related list mentioning that new Intel h/w would have a built in random number generator. I went looking, and managed to find documentation for it ("Intel 82802 Firmware Hub: Random Number Generator", 298029.pdf, from www.intel.com).
Using it appears trivial, but I can't seem to figure out one piece of info: the pseudo-code in it appears to assume that the FWH is mapped into a known location, and the documentation for the FWH ("Intel(R) 82802AB/82802AC Firmware Hub (FWH)", 29065802.pdf) seems to imply that how to do that is proprietary.
Does anybody have any info on this? Are they not going to make programming info for the FWH public? Any chance of using this as another entropy source? Has anybody looked at this?
