I have used 125:20,90 setting for a long time. Without and with SR enabled (SR last 6 months) and device has been stable.
I use Alarmed to put phone into power safe mode during night times (23:00 - 06:45). Enable freqs are 125MHz and 500MHz. This seems to be a bit more power saving mode than 250MHz & 500MHz or single 250MHz or 500MHz when CPU is awake, idle = 0MHz always.
I could try even lower voltages for 125MHz and check if it is still stable.
I have a general question about OMAP PM:
Is it so that DVFS sets OPP according to CPU power needs (when more calculation power is needed, then frequency will be increased also voltage) and SmartReflex tries to autocompensate VDD1 and VDD2 voltages around used OPP (i.e fine tuning based on different paramenters).
- VDD1 domain control MPU&IVA (ARM, DSP, etc..)
- VDD2 domain control on-chip interconnects
Is it possible to see used (current) voltage values, when SR's are enabled?
/etc/power/ -folder files are not showing any changes w/wo SR.
Uptime ~14h with latest KP without any problems.
EDIT: Now testing 125:18,90 setting and N900 seems to work OK (this editing done with that setting and using single 125M freq)
