how to set core's frequency and voltage separately

[linuxdev]

I’ve not been brave enough to force invalid values, but the the method for finding weak points via higher clocks without increases in voltage seems sound. I do not know what each clock value is, so I’m not sure which value would change what. What I’d advise is to step through each clock (via sysfs echo) and watch voltage change, then compare to lines out of the dvfs tables. Whatever sysfs calls it is probably the best clue…how the other values from the tables change or don’t change between those other frequency and voltage changes would give a good idea what value they need even if you don’t know the exact meaning. I would expect that there may be more than one version of a table depending on what power mode it is in at the time. Someone who knows more about specific clocks could probably answer without guessing.
