Does anyone have a driver for that? Even if it's not something that you're willing to open up, just knowing that someone has done it would be nice. (I'm specifically interested in Haswell/Broadwell Xeon, but I'd imagine the programming model is the same for the iMC/SMBus controller on all the recent CPUs.) Thanks, Ravi (rpokala@)
