amazing kernal..i dontt no much abt internals but i like the colors and battery life of this kernal!!!!:silly::laugh:
[Samsung Galaxy Nexus] osm0sis:
Those are mostly right. There're a few differences depending on whether you're using the sysfs or hardcoding though: The 12 for row resolves to the desired 2 due to a bug, but if you're hardcoding you can directly put 2. I would leave the softrt value out of [MENTION=4793042]pkgnex[/MENTION]'s bfq quick-tune, a few of us found that slower than the default. Hardcoded values for deadline and cfq also require the correct scale. I know boype has already done a few of them, in fact he was the first to properly hardcode pkgnex's bfq for tuna and Francisco picked it back for f.K. ;) Of course they're all hardcoded in f.K tuna now so if boype is missing any of them and wants them he can pick them. :good:

Anyway when in doubt, download and read my 950iosettings script which contains all the finalized "Franco's Dev Team" tuning collective values. :)
[Samsung Galaxy Nexus] zoomy942:
I'm trying interactive and noop today.
[Samsung Galaxy Nexus] boype:
It seems like the random reboots only occur with cfq. Correct me if I'm wrong.

And it had nothing to do with what I tried to fix with pre41-1.
[Samsung Galaxy Nexus] Charmacas:
Just switched to deadline and it does not appear anymore. So you're right I think.
[Samsung Galaxy Nexus] lparcshinoda:
I happend to me sometimes and I never set CFQ or OC - I just use default values and sometimes try ZRAM (actually is OFF and no reboot has happened since I switched it off). I'll try to provide more info if it happens again

Hi,

could you tell me what release of the kernel ? r40 stable o r40-2

regular or extended ?

Thanks
[Samsung Galaxy Nexus] JBNex:
Why is no one using the default SIOPlus? Is Deadline better?
[Samsung Galaxy Nexus] Fenvarien:
Sioplus and Ondemandplus are working great, some days ago I forgot to set my usual gov/scheduler combination and couldn't believe how well and battery friendly the kernel defaults are performing. Currently I'm trying Interactive/Sioplus as my new favorite ;)

Sorry for noob question but is there any chance to use fancy on miui? If i can, which version must i flash?
[Samsung Galaxy Nexus] MBQ_:
Flash a kernel version that corresponds to the version of Android the ROM features.
[Samsung Galaxy Nexus] okanb3:
You mean for example miui v5 uses android 4.2.2 so i can flash any 4.2.2 kernel?
[Samsung Galaxy Nexus] thomstrack:
The first time with zRAM enable, first impressions: the multitasking is so much better. :)
[Samsung Galaxy Nexus] daniil1410:
Yeah, thats right. But in my experience only trinity worked. I don't remember if I tried fancy, but franco and ak didn't work.

[MENTION=4615478]boype[/MENTION], should we use r41-1, since the fix wasn't really relevant?
[Samsung Galaxy Nexus] Castro27:
Small question here, is anyone having issues where trickester keeps reseting any custom setting? I'm using pcphobic's settings (thanks for that btw, getting some awesome results here) but after a few reboots I have to set everything up again. Ideas?

Re: [KERNEL][4.2.x] Fancy Kernel (r9) (MAR-04-2013)

I had bootloop when I flashed this kernel coming from cyclone 728 with atom v9. Flash the cwn-jb 4.2.2 stock kernel from anarkia first but still bootloop. Dirty flash rom, gapps then fancy resulted in a different error, system ui failed. Only one that worked for me was do a full wipe then flash rom, gapps then fancy. Thanks.
[Samsung Galaxy Nexus] momomok:
Re: [KERNEL][4.2.x] Fancy Kernel (r9) (MAR-04-2013)

This kernel is very good. Decent performance with exceptional battery life.

Only one issue, sometimes after rebooting it would be running like 4FPS. The phone is working, only except that it is skipping a majority of frames to draw. The solution is to wipe cache and dalvik cache.

What log can help troubleshooting this issue?

You can use a kernel tool like trickster mod. And of course you need the extended version ('ext') of this kernel.

I'm going to test the "extended" Version now, and will report soon.

ok heres the deal, r8 w/ jbs 5.1 isnt as good as r8 w/ jbs 5.0...

hoping when r10 drops battery life jumps back up, was getting 2.5 hours screens but thats been cut in half...but maybe its the rom lol idk
[Samsung Galaxy Nexus] fr4nk1yn:
Dropped by xda to see if there was anything new, in using "Shiny ROM" and don't flash much.

Found this kernel and am thrilled!Responsiveness is remarkable, because of that reason I'm not holding out much good on battery life, I hope to be proven wrong.

Fabulous work!

Google services has been very active lately. I'm on r41-1 and am experiencing massive battery drain. You can see in the attachment.
[Samsung Galaxy Nexus] sajty:
Users on czech Android forum are reporting the same.Google screwed up something,definitely not kernel related.
[Samsung Galaxy Nexus] Jar3112:
Those having the Google battery drain issue. Have a look at your data usage.

Google Services may be trying to download the software update.

If you find Google services data exchange to be much higher than expected (note:see also wifi data usage), have a look at the /cache folder in your phone.

You will probably see a temporary file of a variable size.

That is, Update file is erased on reboot, so Google services download it again. The only way I managed to avoid extreme data usage was to set (only for Google services) it not to download data while not connected to wifi.

[Samsung Galaxy Nexus] daniil1410:
Mmm. That's strange. My sync is disabled and I didn't have the issue on previous relieves. It looks like Google is pulling something from our devices.

I read this article and calculated that Google services used 3.7% of the charge. That is something if Thane into consideration that out did it for only 3-4 hours.

This is not a 4.3 issue since it only occurred today. It may be tuner new CM 29.08 nightly, but I doubt it.
[Samsung Galaxy Nexus] RevengeFNF:
I've noticed the same thing. Im using Cyanogen 10.2 and Fancy r39-ext.
[Samsung Galaxy Nexus] Ci-Fi:
Google Services has download 1.57 GB in 9 days! :o It is listed as background data so I just now checked the restrict background data option - I'll see if that helps. I don't even sync anything through Google. I read in another thread that it might be an attempted OTA update of 4.3, but if people are experiencing it while having a 4.3 ROM that it confusing. I don't want to clog this thread up, so can someone point me to a relevant thread?
[Samsung Galaxy Nexus] daniil1410:
For me Google services has downloaded only 12mb. But still it's active and draining.
[Samsung Galaxy Nexus] Eugene1991:
Random Reboot still occurring on r41-experimental. Could it be an issue with Trickster Mod?
[Samsung Galaxy Nexus] daniil1410:
No. We all use trickster, but the reboots are rare.

I checked trickster. And the phone has been in deep sleep for only 20 minutes and in 192mhz for 10 hours(7 of them while charding).

I think it's the Google services, but i'll run wakelock detector to be sure.
[Samsung Galaxy Nexus] Seraz007:
these are NOT kernel related :rolleyes:

To me, r40 drains battery much faster than pre39-2. I used to get 3 to 3.5 screen on time, but on r40 I can only get 2 to 2.5 screen on time with the same set up.

Can anyone upload the pre39-2 version for me? I accidentally deleted the file and the link in the OP for pre39-2 is dead. Would like to rollback and check the battery usage.

The reboots, are occurring only one some phones. I've been using cm+fancy on 4.2.2 for ~15 days and on 4.3 for another 8 and have never had a reboot or sod.
[Samsung Galaxy Nexus] wasdf:
Yea.. I dont know why someone is having random reboot too. I purchased two GN at the same shop and I give one for my gf, we are running same rom (Cataclysm) and same kernel (r40), for mine it is no problem but my gf one is having random rebooting problem.. I am not able to get the logcat since it is not my phone but she said usually the phone screen is frozen before it start to reboot, if continuous keep clicking the phone then it will reboot (i.e. scrolling a web page and it suddenly frozen, try to click home button or whateven something then it will reboot). However if just stop for a while first, it will NOT reboot. (i.e. scrolling a web page and it suddenly frozen, wait for a few seconds, the page is scrolling again and start to clicking on it, it is no problem.) Hope it helps :o
[Samsung Galaxy Nexus] mick.li:
I'm having the same problem as your gf and I'm using Cataclysm and r40 as well. Actually I'm using pre41-1 right now and am waiting for the first reboot. Could it be the rom?

Or to have one kernel with the possibility to extend RAM if we check an option in trickster mod(bigmem, like in the galaxy s kernels). That will be awsome !
[Samsung Galaxy Nexus] wasdf:
I dont think so, not everyone is having a "developer" mind, if a "normal user" just open and open apps and the phone will crash easily then it is a big problem of Android OS. Let say iOS or Widnows or Linux etc..., there are notification when memory almost get full. (In short, Android OOM will kill app when memory reach to a certain level, so I dont think it is ram problem)

Maybe your WiFi was left on when there was no WiFi hotspot around. So the phone is constantly searching to connect to a WiFi hotspot.

This will prevent your phone from going into deep sleep.

Another thing, by default Android 4.3 comes with a sneaky feature to improve location services but the cost of more battery drain during idle.

If u go to your WiFi advance settings by default it has enabled your WiFi to be active all the time despite u toggling it off.

Disable that feature and you will see better idle drain.
[Samsung Galaxy Nexus] ixi84:
No no no, my phone was in aero mode, not connected at all, neither wifi. the router is in my room, where i sleep :D

that's my default settings for wifi

i changed the second one in "only when connected" and disabled the third one. is it right?
[Samsung Galaxy Nexus] daniil1410:
That's not that important. I have 3% over night drain with it on(52 to 49). I guess Google has done something about the battery.

More RAM on FancyKernel?

I know someone already said here about this, but [MENTION=4615478]boype[/MENTION] , it would be feasible to think of something to FancyKernel?

Google Services battery drain fix

I was trying to fix this Google Services constant keep awake thing(it never goes to idle). I was messing around in the settings to see if it gets better.

So what I found to fix it is to go to Google Settings(green icon in the apps menu), then location and then toggle Location History. And I really mean toggle. Just make it from on to off or from off to on. I tried this two times and both times after doing it Google Services goes back to normal. I don't know why that is.
