I have no idea what that is, I would say its just a random ****. I can check where that error comes from in the driver a little bit later, don't wanna look at kernel stuff today!
[Nexus 4 Original Android Development] Hanny:
are you sure about that? mpdecision is mpdecision, i dont think franco has/can change something on the decision of mpdecision about on/offlining cores, he just protected our rights to customize the min/max frequencies.

it would be good if you can tell me what "other kernels" you are using, as well as the on/offline behaviours you observe. do the 4 cpus stay on constantly? if its about spikes/short-onlines of the 3rd and 4th cores, then yes it also happened on franco. 2 cores means most of the time, doesn't mean the extra cores never ever go up. if possible, please also tell me the game you use to obtain your test results. I will test for you right away :D

without any specified kernel settings from you, this is the screenshot from faux enhanced stock kernel that comes with aokp, same game same track same car, same cpu on/offline behaviour :)

(but lower fps :p)

Re: [KERNEL][GPL][N4] franco.Kernel - r102

I tried out matrix and motley kernel. They didn't use 4 cores constantly but used more than 2 regularly. With Franco it seldom uses more than 2, and if it does it's only at the 300mhz frequency. I only played temple run oz
[Nexus 4 Original Android Development] Hanny:
im not familiar with the cpu hotplug sequences of temple run oz, as i hvnt tested it much since its release.

however even before i change to the two kernels you mentioned and test, what I can tell is that the "mainly 2 cores" behaviour in franco is giving a 55-60 fps on temple run oz on interactive governor and 58-60fps on conservative governor. so whats the point of activating the extra cores in this game? if you see more than 2 cores online on matrix and motley, they are wasting battery + heating up your phone unnecessarily (only applies to temple run oz)

therefore to have some more accurate results i would recommend trying much heavier games such as gta vc or real racing 3, which dont give a near-max fps while using "mainly 2 cores" and has room for improvement if the extra cores wake up.

Hi franco, first of all: thanks for your work, your kernel is awesome!

The way the dev released it is recommended. Everything else is your tinkering. ;)

[Nexus 4 Original Android Development] Whosdaman:
Re: [KERNEL][GPL][N4] franco.Kernel - r102

Stock voltages will always be recommended.

Safety limit, IMO, would be -75 mV from stock per frequency. Don't go below that unless you have a fast or faster binned CPU

I typically run -50 mV even though I can run -100 mV without causing myself any random reboots.

Also, never check "Set at boot" until you have actually used your device with them. Once you find your sweet spot, stick with it.

Edit: wow...people are fast at responding. Anyway, like someone else mentioned, UV reboots can cause data loss. That's happened to me twice so far just because I was testing my phones limits lol. (That's a bad idea and you shouldn't do that.)

Not all dies are created equal. I have seen nominal CPU run at 750mV -1050mV (-150mV, I guess?). I have a fast binned CPU and run at -200mV ever since Franco implemented it.

There is an app call stability test in the play store. You can test UV with that. Run test for 10-15 min and if you have no reboot then you are fine. Normally, if you UV too much, the phone reboot the moment voltage is set anyways.

Mediaserver is userspace, not kernel space. What kernels can do though, is minimize power consumption when the phone is held awake by the Mediaserver wakelock, and any other wakelock.

My man.. Signal related issues are due to modems/radios;);) not kernels
[Nexus 4 Original Android Development] Dr Zoidberg:
If your signal drops are resulting in outline of a triangle on its side (as opposed to light grey bars), its most likely the same problem that I have: the phone knows there is a sim card in the slot, but cannot communicate with said sim card. Try one of the sim reading apps from Play and see if it reads your sim.

It could be a faulty sim. In my case, I went back to my provider (Bell) and obtained a replacement sim card, but the problem persists, so I called Google and obtained an RMA. I'm expecting my replacement phone next week. In the interim, my phone still works, it's just unreliable because of the sudden loss of signal.

I also restored the factory image hoping that it was software related, but unrooting and restoring the factory image did not resolve the problem.

I pray for franco to take away under-volting options. The amount of people wanting to under-volt just for the sake of it is getting crazy. Mind you, then I would need to read through 25 pages of 'why can't I find under-volting options any more'.

I know franco was against volting in the first place, and probably for the above reasons. Under-volting is an art, not a uniform set of instructions, so IMHO asking questions about it on here is completely pointless. If you feel the need to ask any questions relating to voltages then you simply should not be volting in the first place. Simple as!!

[Nexus 4 Original Android Development] bmbanker:
You're correct. Reducing those RIL related wakelocks would help a lot more than undervolting, in terms of battery. Undervolting is more useful for increasing speed.

That's beside the point though. You flash a custom kernel for better battery life, more power, and more capability. Undervolting is a capability, and one that many people use correctly. True, there are people that use it incorrectly, but that's beside the point. That's not the dev's problem. The dev's only job is to provide the best (best battery, best power, best capabilities) kernel that he can provide. Franco's keen thread-watching skills and his app idiot-proofing are both extra things he does for us.

Suggestion for your app francisco :

when increase/decrease cpu voltage, "define at boot checkbox" should be automatically unchecked to avoid "user error"

Ex : from stock mV, decrease by -25 or above.

check "define at boot checkbox"

want to test another mV, forget a number ( 80mV instead of 800mV), dont verify voltage, quit.

later restart and... bam !

So after a mV change, maybe it good we have to re-check this options.

Hi Franco since you have solved the headphone output issue, which is great, could you take a look into the mic phone recording input problem?

The current input gain is too loud that the background noise will be very obvious when recording voice and video. And thus it also makes it unclear when sending voice messages with apps like whatsapp. This issue is already widely discussed on xda and many users want it to be solved.
