Is it possible to dynamically adjust the voltage (Vdd) of the quad-core CPU? I see that the following file can be edited to change the voltage offset employed during DVFS operations:
However, changes to this file don’t seem to have any effect. Btw, I want to adjust voltage independent of the frequency (i.e. to under/over volt for a fixed frequency); therefore a tool like cpufreq-set doesn’t work in my case given that it changes voltage AND frequency in unison.
