the customizable voltage kernel is ready:
The meaning of the voltages (first column):Code:# cat /sys/power/sr_vdd1_opps_vsel 30 30 38 48 54 48 60 60 60 60 60 60 60 67 72 echo "30 30 38 48 54 48 60 60 60 60 60 60 60 67 72" > /sys/power/sr_vdd1_opps_vsel
I have verified that the customized voltages are actually used.Code:stock/normal kernel 30 = 0x1e = 0.975V x 0 MHz = 0 XLV kernel: 30 = 0x1e = 0.975V x 0 MHz = 0
feel free to play with it.
I'm now uploading it to extras-devel.

Start with the max_freq on 810mhz and then test the other frequencies with the "temp command". That is how i did it. I have noticed it can be unstable for me on the higher frequencies.

Do you need this? OPP1 is the voltage at 125MHz so why do you need a 0MHz voltage as it is not going to change anything? I also notice that you have nudged the voltages up compared to ideal. Did that fix your reboot issue? (though of course, given that everything is configurable, it doesn't really matter)

I would guess it has with the voltage settings but as i understand it.. the 810 is on low voltage, the 850 is on normal voltage and the 900 is on the same as 950 which is overvoltage. It is strange it works good on 950 but not 900 as they are on the same voltage.
