I was about to point you to: http://www.freebsd.org/projects/busdma/ But realized that you probably wanted status on 5.x, and not HEAD... a quick look at the code shows that both em and bge are MPSAFE... I can tell because of no references to Giant or GIANT, and that it using XX_LOCK and has functions ending in _locked in them... Maybe we need to expand the busdma project to include which driver status for 5.x and HEAD? -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
