Just out of curiosity, what's the protocol used to communicate with this M3.
I will let Qcom guys answer this :)
This is what we already have on Vexpress TC2 and Juno. Currently M3 provides the information of voltage and frequency for each OPP, but that may change as it's not always constant.
Yeah, I do remember that. But it was always in terms of voltages and so this thing is different here.
That's interesting and this is where it's different and gets complex than what we have today. Do you have more details on this ?
I have written everything that I knew about it :)
I am mainly interested as there are efforts to standardize these communication with M3 and there's WIP protocol development[1]. It would be good to see if this user-case is also considered.
What do you mean by that ?
And yes I am interested in the problem you have explained below but just can't my head around it as I can't fully visualize such systems.
