I was going through the above document and read that "The Krait CPU cores of Snapdragon processors lie on separate voltage and frequency planes. This allows each CPU core to hit independent frequencies and voltages, delivering scalable performance and power levels."

However, if I check the affected CPUs of DVFS policy, I see that for Snapdragon 845 (on a Pixel 3), there are two clusters of 4 cores each. This means that the power management of the 4 cores is tied together. Does that not contradict the above statement (as mentioned on Qualcomm's page)?

Welcome to LQ, CPUFREQobsession.

Please verify that you're running your cpu @ 100% most of the time, or this is irrelevant.

To answer your question, I'm sure the voltage is supplied at a higher voltage than it is fed to the cores at. So it is possible to have variations in positive voltages, but I gather from their wording that they also can vary the negative line. You copied & pasted a sentence or maybe paragraph. I suggest you read the entire article.
