@ktoonsez,
First, thanks for all you do here.
Next, a question / plea for assistance.
In brief:
I'd like to be able to log cpu frequency BUT I want each frequency hop logged BEFORE it takes place. Log first, then switch.
In detail:
Its meant to be a single-purpose debugging utility to find out what cpu frequency a phone is crashing at so its ok if overall device performance is terrible.
I'm trying to find the minimum stable voltage for each cpu clock frequency. When the voltage is set too low for a particular frequency the phone reboots. The reboot appears at random and figuring out which frequency caused it is my goal. The trouble is that all the cpu monitoring apps I'm aware of seem to display cpu frequency reactively after each frequency hop takes place. If the phone crashes after the frequency hop but before the monitoring app logs it then the log is useless if not misleading. If each frequency hop is recorded before it takes place then the log will tell me both where the cpu was and where it was going when the crash happened. That would make identifying marginally over-undervolted frequencies so much easier.
Can you help? Please?
