Linux generates a meric of CPU performance as a byproduct of calibrating a delay loop. We don't require doing any such thing, and so adding it would be purely cosmetic. However, I allege that cosmetic things aren't in and of themselves evil, so long as they don't break anything in the process.
I would like to generate a number that will hopefully be reasonably compatible with the one Linux spits out. The best method I have come up with is to have a similar (the same?) count down loop in assembler. Have it count down from 1,000,000 and see how much nanotime() has gone by. NANSPERSEC/nansused = bogomips. A 1 bogomips machine will take an extra second to do this (anything likely to be even able to run FreeBSD should exceed 1 BM - yes, ha ha), and a kBM CPU can do it in 1 ms. Perhaps in the future a prescaler might be required, but this whole thing is just really chrome anyway. Would anyone scream and projectile-vomit if I added this to identcpu.c?
