Sure I would not mind going lower, but 700 mV is pretty low already. Try playing around a bit. Will make 650 mV lowest possible voltage. Is that okay?

Not a single SOD for me, same I got fast binned chip. But maybe it can be ondemend settings you have, or something else.

Yeah that would be great for me. Thanks a ton!

I have found a reasonably conservative uv which is very stable for myself. But, there are quite a few adventurous people who are able/willing to go till 600.That is why I asked.

Touch Control fixed kernel is being uploaded. This time fixed for sure :D

Download link will be updated in OP, along with changelog. Removal of all debug was cause of problem.

New link for fixed kernel...

Changelog:

Linux 3.4.27

Westwood+ as default

TouchControl Working

Could not remove all debug as before, so kernel size back to 6 mb.

Hit Thanks, and hopefully this is today's last build :D

Does high UV cause SOD? I've started getting it as well and I've UV'ed -162.5mV across (-62.5mV extra since the kernel is UV'ed -100mV by default).

I might just leave it at -150mV. Nice and even and guarentees stability, but I wanna know if UV really causes SOD's.

Re: [KERNEL][UV][Linux 3.4.27] Harsh Kernel build Jan-24-fixed

But it could be that your chip isn't getting enough voltage at lower frequency range giving sods while sleeping.

I didn't see if you were using the in kernel implementation of s2w. It has been known to cause sod as well.
[Nexus 4 Original Android Development] Harsh:
Try making your voltage at 384 MHz little higher maybe add 12.5 mv

Yes should be network, wifi was never changed. Its all stock :D

s2w dont have sod at all. Sweep2wake used to cause unresponsive screen but is fixed now. Cant be considered as SOD at all.

I use s2w all the time when I am using my phone for a day, at night I disable it. (sweep2wake widget on screen very handy).

[Nexus 4 Original Android Development] Harsh:
Re: [KERNEL][UV][Linux 3.4.27] Harsh Kernel build Jan-24-fixed

Thank you so much for feedback...

Compressed version is not debug less version. Compressed version is just using xz compression instead of gzip and that is why it's 30% smaller. But debug free, lower UV version I am using is all debug disabled and more -50 mV UV across the board + -25 mV UV more on frequency range 900 to 1200 MHz (fast chip).

And those of you having SOD don't need to up your voltages, our phone can handle -100 mV even on slow chips, just check your apps and settings. Uninstall any kernel controlling app may help drastically. Get me logs of possible, could help a lot.

And currently gamma control only with fauxclock.

Hope I answer all of you, if missed i am sorry.

Dont worry about UV much, my kernel minimum I have set is 700 mV. So it is obvious you cant go below that.

And still I dont think its possible to really run 1 GHz at 600 mV. Its against science, PURE MAGIC.

My kernel got krait retention, a special low power mode from Qualcomm. Maybe thats effecting you. Also governors and even toolchain may have effect on your ability to UV.

I really suggest you not to UV so low, It is harmful for your CPU in long run. Low UV is not always good for CPU. When you give less power to CPU than required, even when you dont get reboot there is stress on CPU. As it has to do same amount on work using less energy. Its like running 10 km on 1 banana.

Dont turn off mpdecision on my kernel please. Because when you turn off mpdecision in my kernel, your no cores will go offline when screen is on. They would hover at minimum 384 MHz forever.

This kernel comes with no CPU hotplug like others, we are using default Ondemand governor from qualcomm which was tuned for mpdecision.

And mpdecision is what controls cores in here, and takes them online/offline according to additive load.

Ahhhh I did see that all cores were online. Thank u for the quick reply I just turned it back on.
