I just came from Franco Kernel (not out of any bias per-say, more because I have a nexus so why not!) bought both the main app and display app. I have to say, your apps UI's are much more in line with androids guidelines as far as I can tell. I prefer the usability and clarity in your apps (things like the note telling you what MPD is.) For the life of me I'll never understand even half the options in the display app, but maybe one day I will try (FKU has the edge here in it's simplicity I suppose.) Anyways despite other things I have read that have no business being brought up here again, you seem to really know what you are doing, so enjoy the beers from me. Here's hoping my battery tests go well using your recommended settings. :)

intellidemand governor

FIOPS I/O

Undervolt by 100 (not all devices can handle it. Some can UV more. I probably can UV more.)

EMMC Entropy off

Re: [Kernel] (version 012) Mako (UV Control/CPU/GPU OC/Hybrid Linux 3.4+) [Mar-26]

OK, being that the thread has almost 10000 posts, cut me some slack for this next question. Before I ask, I want to say I love your kernels faux, I've been using since I got my G2x shortly after launch and I wish I could use this kernel now. My question is, what's the deal with some market apps saying invalid or not signed correctly, multiple random reboots, my bootanimation flickers, the list of no bueno that's occurring is quite extensive. Before everyone tears into me, I used to be a news writer for XDA and still am an RC, I know my way around android. I've oow everything I could think of, dpi, clear market, reinstall market, reboot, reboot recovery and wipe dalvik, once again, the list of things I've tried is endless, oh, and mass suicide of all apps by way of f/c. I've tried this kernel with all latest versions of root box, pacman and Paul's modaco rom(cm10.1). I've bought fauxclock and have tried all recommended settings and then some that were not. I haven't posted a log as of yet because I don't know what events are of interest and there's a possibility I'm being a dumbass. Latest Gapps and obviously, a Nexus 4. Any help or guidance would be greatly appreciated and your awesome faux, I think this is probably on me, but I've really tried with all the knowledge I have. Thanks, please don't burn me to a total crisp if I'm being a d/a. Oh, one last thing, as of now, the only fix is to wipe device clean and flash morfic's kernel with whatever rom, the fact that his doesn't give me any bs with the exact same set up/installation method.... ect. This makes me think it isn't something I'm doing wrong.

I've tried both the mainline and tbu of 012, but the problem still existed on 011. Always a full wipe, rarely, if ever, dirty flash. Also, once booted, I try wiping dalvik again, it rebuilds on reboot, then f/c's across the board for every app. As a side note, I've never even trolled franco's thread just because of the boot image crap. Like I said, after a full wipe, reflash everything the same except change to trinity kernel and everything is totally fine. I even tried restoring the device id with titanium bu. No va. Maybe I have bad copies of faux's kernel, I'll re - d/l and let everyone know. Thanks guys for the help and quick responses.

The last boot reason is "watchdog".

I have no idea what that all means >P

What i did was:

1) instal latest TouchControl

2) disable slide2wake

3) load TouchContol and set it to load on boot

4) Install Buzz Launcher

5) leave my phone to go to eat (it was on buzz launcher first screen, a welcome screen of sorts i think)

6) come back and wake it with touchControl gesture

7) see that phone was not respondig

8) switch screen off with TouchControl gesture

9) it then rebooted (after screen off i think)

im on 012u

[Nexus 4 Original Android Development] LadFromWales85:
Damnit :(

I managed to somehow swipe the voltage slider down when swiping between screens in the app :(

The phone took a little while to boot again, but has lost the data for a lot of my apps! :( Fauxclock is gone, Titanium can't see it, and I can't reinstall it from the market!

Will do a full wipe as soon as the next beta for Paranoid is up.

Do wish the sliders had an ok button, or at least a delay before they are actioned.

Bah humbug!
[Nexus 4 Original Android Development] MatAuc12:
Chips come with a set voltage. Usually that voltage is higher than required because not all chips are created equal and its the safe range for stable operation. Since that voltage is more than required for the majority, you can fine tune and find the minimal operational voltage for your chip. Lower voltage means less heat and less power drain. There are no long term side effects, in fact lower voltage usually means longer lifespan.

The fact I had to explain though, means you should read more on the subject to know how to undervolt and how to test the voltages. A more common connex subject is overclocking. By learning how to and what is overclocking, you can deduct what undervolting is. Overclocking is more popular with computers to increase performance and has limited use for phones (especially overpowered phones like the Nexus 4), but it uses the same principles.

Higher frequencies require more voltage, if you look at my screenshot, you see different clocks have different voltages.

PS. Like I said, all chips are different, so do not just copy my voltages, it could very well work, but very well cause instability (freeze/reboot).

[Nexus 4 Original Android Development] MatAuc12:
Faux, do you have the intention to lower the minimum voltage the kernel allows? It may sound trivial to some, but for me, not running the optimally low voltage is almost a deal breaker :p.

BTW, do you have a quick explanation on what is Eco mode exactly? Or perhaps a little "how it works" so we can deduct for ourselves if we should use or not (although I suspect we all should, it would be great to know what behavior we change)
[Nexus 4 Original Android Development] rootuser11:
It is there.
[Nexus 4 Original Android Development] rootuser11:
doesn't this simply power off two cores? so only two cores work at max? at least I believe that's how it works on Optimus G.

[Nexus 4 Original Android Development] lookitzjohnny:
For people who under clock and it doesnt stick heres what i did.

In Faux app 3 window/tab manually put in which freq you prefer in the LMF Max Freq:

LMF Max Freq: 1242000

Those are the freqs i manually inputted and it seems to stick.

[Nexus 4 Original Android Development] faux123:
it is only with intellidemand. so you will need to select intellidemand in order to see it.
[Nexus 4 Original Android Development] rootuser11:
time to time it still jumps up to 1.5Ghz and uses third core, and using eco mode definitely causes a bit of lag here and there.
[Nexus 4 Original Android Development] faux123:
Intellidemand Eco mode is way more complicated than just simply turning off 2 cores :D

Intellidemand Eco mode re-adjusts its core algorithm and re-calculates the new load required to enable the remaining cores. If I simply turn off 2 cores, the performance would not be optimal.
[Nexus 4 Original Android Development] faux123:
the occasional jump is due to m(ake)p(oor)decision interfering with my kernel :(. In the next version of the app, I will add a switch to disable mpdecsion.

in the meantime, you can open up terminal emulator and do

stop mpdecision
[Nexus 4 Original Android Development] rootuser11:
@faux the mpdecision is stopped and it does not go over the limit I set in your kernel app! :) in order to restart the mpdecision, do I simply type "start mpdecision" and lastly, does it stay after reboot? thanks,
