Kernel panic

Woke up this morning and the phone had restarted, was sitting on my desk all night. Running r33-test from the 7th

How do you get wake lock detector to show kernel wakelocks like that? I don't have that option on mine.

[Nexus 5 Original Android Development] franciscofranco:
Can you show me more of that log? Doesn't have much info in there, thanks.

Thanks for the log.
[Nexus 5 Original Android Development] :
In getting 6+ hours SoT with r33... Thanks Francisco keep it up, your work is amazing! :good: ;)
[Nexus 5 Original Android Development] blueren:
Um. Extremely off topic. The latest Google update had introduced disappearing icons and widgets on home screen upon reboot. Is it just me?
[Nexus 5 Original Android Development] Kpoch:
Its just you. For me after every reboot it changes my brightness from 20%,to 50% and my MAX ringtone volume to a 80% don't know why but I reboot my phone once a week on a normal usage

It tried the last r33 beta with my under voltages from r32 and get reboots then I raised 25 mV at 300 MHz and not more reboots. I have -75 mV globally and 650 mV at 300 MHz. I will try with the new beta with 625 mV like in the r32 to see if I have reboots.

[Nexus 5 Original Android Development] Tzfardaya:
No idea why a red app would keep the phone awake... :P

You're 2 biggest wakelocks (bam_dmux, and wlan_rx) are both system/network wakes... not much you can do about them... the third (powermanagement) is a total of the partial wakelocks (app wakelock) which are normally the only ones you have much control over, by uninstalling the offending apps...

I'm on r32 and got random reboots/bootloops since yesterday. Logcat: https://www.dropbox.com/s/cb9u3ko4cf40iyk/2014-02-08-19-10-56.txt

last_kmesg would be more usefull for kernel errors than logcat... seeing as kmesg is kernel log and logcat is apps log. :P

[KERNEL] [GPL] [N5] franco.Kernel - r32

Thanks but having a hard time getting this log. I looked under /proc/ but there is only a kmsg . :(
[Nexus 5 Original Android Development] marcusva79:
Sup Franco peeps! On the apk didn't see were all the users gamma controls were! I asked earlier if anyone had a link to it but they said it was in app itself. Franco again thanks bro. Bought the app again for my new email? Franco fo life!
[Nexus 5 Original Android Development] GeekMcLeod:
I use an app called sys log to get my last_kmsg.

Posted from under your bed.
[Nexus 5 Original Android Development] Westi01:
Okay, got this extracted with sys log. But there was no last_kmsg log :(
[Nexus 5 Original Android Development] educk:
No last_kmsg = no kernel panic = not the kernel was responsible for the reboot...

Also, posting a logcat taken after the reboot won't help at all. Logcats are useful if you know the exact situation where the reboot might happen and you are able to catch the log before it.

[KERNEL] [GPL] [N5] franco.Kernel - r32

Okay, seems like I have to investigate further. Thank you all. :)
[Nexus 5 Original Android Development] :
Yupp -50 uv, that was the issue?
[Nexus 5 Original Android Development] franciscofranco:
Maybe.
[Nexus 5 Original Android Development] :
Lol well do brother, these are stock correct?
[Nexus 5 Original Android Development] franciscofranco:
It varies from hardware versions. Untick set on boot and reboot.
[Nexus 5 Original Android Development] The Gingerbread Man:
The thing is making something that will work for all. Just because you can get lower it doesn't mean other people can. Imagine the reaction with seriously under volted kernel and no one can get it to boot. There would be hell to pay. This is why you can change it your self
[Nexus 5 Original Android Development] :
I just thought we all had the same "stock voltage" for a sec but franco explained it to me, thank you for the quick reply my brother I gladly appreciate it.
[Nexus 5 Original Android Development] treehugger38294:
I get better standby time with stock than with Franco. Running Mahdi ROM. Use battery life numbers are about the same with stock being slightly better. I don't know how this happened. Maybe this is a bug with r32. Didn't occur with r31.
[Nexus 5 Original Android Development] Beremus:
Same here. Since I flashed r32 my battery seems to be worse. Well, this post isn't really constructive tho.

I'm only able to get 3h15 on-screen while only texting on hangout, wifi on, with facebook and other stuff being greenified.

Well. I'm looking foward for r33.
[Nexus 5 Original Android Development] The Gingerbread Man:
You are welcome and you might find if you follow the link in my sig you find some useful information about a whole range of things to do with this kernel, perhaps other less experienced guys / girls might like to also. Follow the link the the Franco learner lounge which is a place better to answer beginner level questions :)

Greenify might help but you will find turning off things you don't need like WiFi if your not on a network you can connect to will help. As a starting point look at the settings I run. Then check you wakelocks from other apps
[Nexus 5 Original Android Development] mprziv:
Hey guys. Just wondering if someone could point me to where I can find the latest testing kernels.

[Nexus 5 Original Android Development] imablackhat:
Franco do you use art or dalivk?

[Nexus 5 Original Android Development] franciscofranco:
Obviously Dalvik, Art is not ready...
[Nexus 5 Original Android Development] bobby janow:
As soon as xposed is compatible.. Then we are ready. Ot.. R33 is release ready.
[Nexus 5 Original Android Development] adriangb:
On r32 and latest Omni I'm getting FC and random reboots. Please tell me if this is all that's needed to troubleshoot.
[Nexus 5 Original Android Development] HenryDCase:
I'd say ART is "ready" when it is the default runtime. Say, next Android release / next Nexus release. Until then, it's a devs experiment.

That said, as soon as Xposed is ready, I'll try it out. Already run it on my Grouper with Franco and Slimkat.

[Nexus 5 Original Android Development] mimmolm:
I love you kernel [MENTION=3292224]franciscofranco[/MENTION] but in gaming there are many lags compared with the stock kernel :/
[Nexus 5 Original Android Development] Savant:
Then stick with stock since that kernel uses mp decision.
[Nexus 5 Original Android Development] mimmolm:
This kernel is the best and with fku (paid version) you can customize a lot of device's settings ...is difficult to give up to it!
[Nexus 5 Original Android Development] franciscofranco:
Can you describe the lag? Is it when the device gets hot? Can you increase the thermal throttle threshold to 70 and report back? Thanks.
[Nexus 5 Original Android Development] Rxpert:
You're going to need to provide much more info if you want a solution
[Nexus 5 Original Android Development] mimmolm:
There are many lag in intensive 3D games such as GTA and Asphalt 8...I tried to increase thermal throttle threshold to 70 but the result is the same :/ actually i'm on Cataclysm ROM + stock kernel but i like your kernel for the customizations that it offers
[Nexus 5 Original Android Development] franciscofranco:
What happens when you increase the threshold to 80?
[Nexus 5 Original Android Development] mimmolm:
There are lags also when the device it's cold! I think it's related to CPU frequency management
[Nexus 5 Original Android Development] franciscofranco:
I can play RR3 without any lag, so I cannot help. Try to play with the governor settings for a while to see what improves your experience.
[Nexus 5 Original Android Development] HenryDCase:
RR3 and Asphalt 8 with serious UC on both GPU & CPU based on Vomer's settings. No lag and no crashes. My only issue on this device ever has been that I am a Sprint user, so whenever I need mobile data, my battery drains quickly due to low signal.

I UC my GPU to 200, no per app modes, and my games seem fine. Using r33 back through maybe... 29(?)

[Nexus 5 Original Android Development] ArisenDrake:
I don't know if I am the only one, but if I use the franco.Kernel Updater App (the Paid one) the colour profiles do not stick after Reboot, even though I set them to apply after reboot. I have to load the profile again (select it again). Using r32 btw.
[Nexus 5 Original Android Development] franciscofranco:
Have you screen off and screened on again?
[Nexus 5 Original Android Development] ArisenDrake:
Sure I have :)

Basically it works, but if I set it to apply after reboot, the settings won't stick after reboot. So I have to go to the app again and select the profile (Piereligio_True_RGB btw) again.
[Nexus 5 Original Android Development] b_rangel29:
I've noticed this as well. On latest r33. I've also cleared all data and cache after flashing new kernel which I saw was suggested within the thread and still color profiles do not stick after reboot.

Also, when it is said to adjust your thermal throttle threshold to help with game lags, would that be the "CPU temp threshold" under Kernel Settings within the FKU app?
[Nexus 5 Original Android Development] adriangb:
[MENTION=3292224]franciscofranco[/MENTION] can you take a look at the logcat I put up?
[Nexus 5 Original Android Development] :
That use to happen to me but that problem got fixed with the newest update
[Nexus 5 Original Android Development] ArisenDrake:
Newest version of what? Kernel or App? Kernel version is r32 and app 11.3 for me. Can't use r33 because I am using carbon, which is not a CAF rom.
[Nexus 5 Original Android Development] juancaperez2000:
you shoul not get a problems with r33 and Carbon they move to Slim Trees. I flashed yesterday with out problems
[Nexus 5 Original Android Development] franciscofranco:
I use set on boot on colors every time, it always sticks. It takes about 2 or 3 minutes sometimes for the BootService to come up and do its job...

What logcat and what am I looking for in the log?

?

r33 is for non CAF roms...
[Nexus 5 Original Android Development] ArisenDrake:
Hmmm ... I guess I should read better ,,, testing r33 now.

EDIT: hm ok r33 works just fine, but the profiles are still not applying after reboot.

Just checked it with Display color app - choose profile, switch off/on to apply settings, check set on boot icon, reboot - all settings are applied.
[Nexus 5 Original Android Development] GeekMcLeod:
Just gotta say I'm loving the latest r33 test. 50% in and at 2h 50min SOT. Browsing the interweb, xda and listening to music. Along with a 3d parallax background, although I don't know how battery intensive it is. If it stays the same, I could get around 6 hours SOT and that would be the best I've ever gotten with franco. Usually it is around 4-4.5
[Nexus 5 Original Android Development] Seadra:
It works flawlessly, but just not when we reboot. We have to go to that app again and set it up again. App works great, just not with reboot. Checked like 10 times wuth stock , and many other roms.
[Nexus 5 Original Android Development] Wenzo2:
The stock thermal throttling go down the Max cpu freq very often and I think it acts also when the CPU isnt at 60° yet. In my opinion you have to decrease the CPU freq in a larger time. For example if you set 60°:

55° 1,9ghz

56° 1.7ghz

57° 1,5 GHz

58° 1,5 ghz

59° 1,4 GHz

60° 1,2 GHz

61° 1,2 GHz

62° 1,2 GHz

63° 1,1 ghz

64° 1,1 GHz

65° 1 GHz

In my opinion the lag isnt related to the CPU freq... In dalvik I use chrome and I've lag with 1,5 GHz (seems that the frame rate is 25-30 frame for second) but if I use fps meter that shows 54-60 fps.

Now I'm in ART and chrome don't have a lag (1,2ghz) In my opinion you must try ART and if one of your installed app is incompatible you go back.

PS: I don't know anything about kernel and thermal trottrling I'm sorry if Ive do a stupid statements.

PPS: sorry for the English ! I hope you can understand that.
[Nexus 5 Original Android Development] benthian89:
Did you follow the steps mentioned?

You have to apply profile then check the set on boot.

If you select set on boot before applying the profile, it will not be registered.
[Nexus 5 Original Android Development] Seadra:
Yes, I did.
[Nexus 5 Original Android Development] big_adventure:
And are you waiting at least a couple of minutes after a reboot before screen off/ screen on-ing?

Battery life is great :)

Exactly 15 hours, 4 of which are screen on time. Still have 14% left. WiFi and sync were on the entire time (mobile data off).
[Nexus 5 Original Android Development] Dudebowski:
Correction... unbelievable, never before seen battery life. Franco, You deserve every penny you're charging for the app. If this kind of performance is possible on a Samsung device, someone please say so... I could NEVER get more than 18 hrs out of a charge, very well may never buy from them again (their flagrant violations duly GPL).

Might I humbly ask the developer for some focus on kernel security considerations, where possible, if you haven't already done so? If you have, could you kindly define some of the major points? Considering the state of affairs in network computing today, any bit helps. It seems if any platform is the largest growing target, it's what we're running on.

[MENTION=3292224]franciscofranco[/MENTION]

I don't want to annoy you with feature-requests, so ignore this if it sounds too stupid, but would it be possible to have MPDecicion-control in the kernel (and the app)? I know you wanna keep it straight, but it would add just a tiny bit more control over the device's behavior, for those who wish to have this control.

I really respect the work you do, and I don't want to annoy you, it would just be a suggestion....
[Nexus 5 Original Android Development] mimmolm:
Thanks for your help [MENTION=3292224]franciscofranco[/MENTION] ! I'm trying to play with governor settings
[Nexus 5 Original Android Development] combatdeity:
Franco has has his own implementation of mpdesicion, plus its closed source, so I don't think you can really do much with it anyway.
[Nexus 5 Original Android Development] Diesel779:
Hi, First thank you Franco for all your hard work. I'll purchase you app and donate via paypal if possible. I have 2 questions: 1: when will r33 hit stable and 2: Is this a flash and forget kernel? i.e once I've flashed it I don't need to do any tweaking?

I compile my Kernels on Linux and I spend a great deal of time removing unneeded features from the kernel for security and speed purposes. So If this kernel is flash and forget that would make my day.

Thanks again.
[Nexus 5 Original Android Development] ChriKn:
1) In two Weeks,

2) It is the motto and probably said every five pages or so...

In every case, it is rock solid, perfect balance between battery and performance and even if it doesn't need to, it gives much customisation, so that everyone can have their own perfect kernel.

Try it and you will not be disappointed ;)

Green line fix!

[MENTION=3292224]franciscofranco[/MENTION] after some debugging and messing around with the kmsg, I managed to fix the green line which appears on your kernel.

The culprit was: https://github.com/franciscofranco/hammerhead/commit/8294538bc334fc52e3973ee396c367b849c32523

The mdp pipe simply doesn't like that solid fill which was applied.

You can find my approach here: link.

Hope this will put an end to those green lines!

This is my voltage table with R33 Test on PVS3 :

300 MHz

650mV

695mV

729 MHz

715mV

883 MHz

745mV

960 MHz

755mV

1036 MHz

765mV

1190 MHz

785mV

1574 MHz

845mV

1728 MHz

868mV

1958 MHz

908mV

2265 MHz

963mV

My only problem is with the frequency of 2265 MHz, I did a lot of tests, but the maximum voltage that can get off is 962.500 with any kernel, I can fall below this threshold but I have random reboots. It seems normal that a difference between 1958 MHz and 2265 MHz?

So I used my charger last night and I never thought this would cause any difference but wow. I think I unleashed Franco's lullaby. I got over 7 hours standby with only 3% drain. Etc etc.

Its always 2weeks :D everyone knows that.

[Nexus 5 Original Android Development] The Gingerbread Man:
Yeah I'd guess its normal to have a few jumps in power required for each speed. It can give you a good idea for under clocking by checking the power required for the different speeds. For instance, 1728 MHz I have set to 905mv but 1958 MHz needed 945mv and 2265 MHz needed 975mv which is a fair amount (70mv over 3 speeds). So that will help with battery 3 ways, less cycles of CPU per second and less MV used and less heat generated. You seem to have been quite accurate with your voltages, I have only tested to the nearest 25 I'm not sure there is much point trying to reduce it further as the savings will be tiny vs potential instability.
