[Haifux] reading electric current registers on CPU

I'm trying to find the way for the user-level program to read the electric
current sensor of a CPU to compute its  power consumption (given vCore it
should be easy). I'm trying to use lm_sensors, which actually mention the
support of  this kind of info, but I can't seem to have the kernel module
which exposes it to lm_sensors and does the trick.

Googling is not that useful for the query "reading CPU current  register "
brings up tons of info with "current" in the sense of momentarily, rather
than electric current. ...

Any idea ?
