That's not the point I was getting at. Just simply don't do the things to reproduce the reboot.
[Nexus 4 Original Android Development] limeaide:
Wait let me understand this, you are not suppose to use the device like it is intended?

The user said they uninstalled chrome beta and had a reboot after while trying to make a phone call. If I cant use my phone like ya know a phone then what is the point of having it?

If that is not what you mean, it might be beneficial to clarify. Because Im interpreting it that way.

Franco did you remove the single option to clear app data when flashing a new kernel? I cant seem to find it in the newest fKU.

I've had two Sleep of deaths (I think) running 183 jss with 13th Sept CM nightly. The screen was off and it wouldn't turn on. I had to hold down the power button for 10 secs for anything to happen. It occurred while charging and off charge

back to 182 'cause of random reboots
[Nexus 4 Original Android Development] Dark Emotion:
No reboots on r183 over here.
[Nexus 4 Original Android Development] PeQuEsan:
Talking about reboots... I didn't have one with r182, but with r183 I've had some of them. Anyway, I've had just 1 every some days, so no big deal (and it could be the ROM, obviously).

BTW, I've seen 3 different kind of reboots:

- Complete reboot. Uptime gets reset.

- Soft reboot, where uptime doesn't reset, but you must enter your SIM PIN.

- Soft reboot, where uptime doesn't reset, and you don't have to enter PIN again (in fact, if this reboot doesn't happen while you're using your phone, you don't even realise).

Question 1: Any clue what could cause each one? Or even, can we discard kernel in any of them?

Question 2: Which of them generate /proc/last_kmsg? All? Only complete reboot? It's difficult to see because there's no absolute timestamp in that file...

Thanks a lot Franco.

Gamma correction

Hello, I don't seem to be able to change the gamma settings through the updater app. Actually the values can be throttled but I don't see any difference even if I max or min them.

Try to lock the phone and unlock it again.
[Nexus 4 Original Android Development] dresnu:
It works. Thanks!
[Nexus 4 Original Android Development] Arstoien:
I would think if it's kernel related, it should only be complete reboot. Any soft reboots should be related to the rom or an app. Please correct me anyone, if that's not the case.

On that note: a good app to track these is Bootlog Uptime.
[Nexus 4 Original Android Development] PeQuEsan:
Thanks for pointing that app. I'm using Uptime widget to track reboots, but that app seems more complete. Thanks a lot.

[Nexus 4 Original Android Development] fozzie:
No. You don't use flashify to flash a ROM. You can flash boot (kernel) images, recovery images and flashable zips; not ROMs.

Follow the instructions.

This is getting rather OT now. There's plenty of guides and tutorials elsewhere about flashing ROMs (and flashing in general).

Amazing battery life with r183. The drain over the night has gone. I charge 3 times the battery with r183 and I have every time minimum 5 h SOT. The benchmarks are really good, I can beat Ipad 4 in 3D Mark. Thanks Franco!

JSS kernel works fine with the JLS build. And I don't know if it's physiological but it seems faster. Might be placebo.

What kind of log would prove useful for SODs ?
[Nexus 4 Original Android Development] karthi89:
So here are my settings. And am very happy with the battery life.

Max-1512

Min-384

Governor-ondemand

Scheduler-noop

Max gpu-200

Higher load threshold - 80

Suspend freq-384

Cores on touch-1.

Uv- 175 for lower freq and 125 for last three freq.

And there is not even a single lag with the above settings. I don't want people to compare with the my battery drain graph (usage patterns will vary from people to people). Wonderful work Franco. Started enjoying ur kernel like I used to with my LG p500 with urs (no not this one :D)

Edit: My cpu type is fastest.

If your phone reboots, then a last_kmsg will tell you what caused it. If you're having apps force close, then you need a logcat.
[Nexus 4 Original Android Development] giovaorama:
Sorry for the OT but i don't understand if these deadlocks happen just on mako with a jss rom.

Do other devices suffer of the same problem?

Inviato dal mio Nexus 4 con Tapatalk 4
[Nexus 4 Original Android Development] Andre_Vitto:
i think only aosp
[Nexus 4 Original Android Development] JNewms:
The dead locks are due to ROMs with the JSS tag. Some devs (like slim) are using JSS, but changing a commit or two to JWR, which fixes it. If you want to avoid deadlocks, you'll need to be on a ROM that is using JWR kernel
[Nexus 4 Original Android Development] franciscofranco:
Soft reboots are rom related.

Hard reboots can be either Kernel related, app related if the app tries to call something from the Kernel and it gets into trouble, and can be hardware related and the Kernel shuts down the device to prevent further damage.

JSS Kernel. There are no Kernel changes on Android-4.3_r3 on Mako. On Flo there is only a single change.
[Nexus 4 Original Android Development] Arstoien:
Franco just to draw your attention to a small bug, that hasn't been yet fixed: input_boost_freq_duration doesn't stick regardless of the app settings. Gets reset to 1000 on reboot.
[Nexus 4 Original Android Development] stratosk:
Ideally, kernel should protect itself against 'bad' apps. :)

If an app can panic the kernel then it's kernel's fault.

Thanks, I will add a note to Google Keep for a reminder.

Threads been moving fast as hell last few days, I can barely keep up.

No reboots anymore with r183, but I also uninstalled Chrome Beta so I'm not sure if its that or r183. Haven't changed from ondemand because the battery life has been so stellar for me since I've flashed r183. Might try interactive today and see which is better.

Has anyone else noticed that the haptic feedback is much weaker in r183? I usually dial it down to 70, but now it's set to 100 and still very weak. With PA's stock kernel it seems normal.

Not in my case - I still have it at 70 and it is exactly as it was before r183.
[Nexus 4 Original Android Development] steviewevie:
+1, that's basic operating system principles. If the kernel panics it's the kernel's fault.

Sure, a particular app (e.g. Chrome Beta) could cause the OS to go through a sequence of steps which triggers a panic or reboot, but that's not necessarily the app's fault. Though it may be easier to quickly patch the app to work around the problem, rather than fixing the OS.

Like I said before... I had those issues with the OS wakelocks... Gdrive and some other apps and Gservices are keeping the device awake.... I disabled autosync on Gdrive and greenified it along with a few more apps like Keep.. And problem solved... Back to an average of 10 minutes of Android OS... And you know the rest.

Try converting all google apps (not Gplay) to user apps and greenify them all... That will hibernate them until you use them again... Gservices suck right now... And it's not like I'm downloading magazines and books everyday to have them running in the background.

Hello everyone. I'm new to this thread, so sorry if i'm doing something wrong. Can anyone tell me how to undervolt to get the best battery life + Smoothness. I'm using Stock JWR66Y with Franco 183 and i have Franco Kernel Updater.
[Nexus 4 Original Android Development] jimbohurt:
As far as my knowledge goes, undervolting doesnt give better battery life or smoothness. Its just for less heat, which in turn, less thermal throttling.

Now underCLOCKING on the other hand could potentially help battery life but i would try some other things first.
[Nexus 4 Original Android Development] zephiK:
undervolt in the app... leave it default.
[Nexus 4 Original Android Development] Thanak:
Will it affect responsiveness?
[Nexus 4 Original Android Development] jmudrick:
Franco has done the work for you, leave things alone. If you really must undervolt - 100 is typically safe on slow processor but don't set revised voltages on boot. I doubt you will see impact on battery life from undervolting .
[Nexus 4 Original Android Development] sordna:
Actually, it helps somewhat, since there is less energy wasted as heat.

No. Anyway, try undervolting by 50 or 100mv and see how it goes. If you notice instability, reduce the undervolting. If it's rock solid in all conditions (try it for a few days) then you can attempt to undervolt a little more.
[Nexus 4 Original Android Development] Thanak:
I -50 volt. Will see what happen.
[Nexus 4 Original Android Development] franciscofranco:
You seriously have an app fúcking you, or maybe some connection problems, like a noisy Wi-Fi connection or something. I dunno, my Android OS is really really low.

Do you see a throttling message in /proc/kmsg? I can't raise the temperature above 60C no matter what I do, so something its broken there.

Titanium Backup can do that.. but I think you need the paid version..
[Nexus 4 Original Android Development] MuertoKo:
I used to be there, but when it comes to -100mV stable UV like in this device... well, even if it's a 5% it's good enough. On other devices such as S3int you had to tweak ABB voltages even just to reach a decent -50mV UV... that wasn't worth really... Here? Perhaps, why not trying as long as you keep it pure stable? I'm not a fan, but since I can handle -150mV stable UV here I'm pretty happy with it, it works, it's physics, just perhaps not in a noticeable range... but can't harm :P
[Nexus 4 Original Android Development] steviewevie:
Watchdog isn't an app, it's part of the Android OS. So the OS didn't crash (panic) but it decided it needed to do an emergency reboot for some reason. Someone else might know more details but I'm guessing the watchdog involves watch out for critical things becoming unresponsive.

I raise the hotplug value to 75. Suits me great and there's not that much hotplugging for simple stuff. Raise the gpu sample time to 200 ms and lower the input boost time to 500 ms. I use interactive and my animation scale is 0.5.

I've got two other modes: Dual core (same but with hotplug threshold 100%, gpu UC to 200, and touch boost freq lowered to 1026) and power saver: hotplug 100%; touch boost and hispeed 702; timer set to 50k; gpu UC to 128. Slightly laggy but sometimes you just need more juice.
