First flash the "F2FS-EXT4-Lollipop-Kernel-Cl3Kener-Kexec-Permissive" to pass from "Enforcing" to "Permissive".. after you can flash code_blue...i've done the same and it's working

Grazie amico mio !!!
[Nexus 5 Original Android Development] pianistaPL:
Flashing other kernels before Code_Blue does completely nothing because Code_Blue uses own ramdisk. Flashing f2fs kernel by Cl3kener does matter when after this you are flashing kernel without ramdisk, like Uber or ElementalX.

Is it me or everybody else is getting huge battery drain in idle usually 8-10% overnight with Wifi, Cellular off.

PS: I just charged the phone to 100% and it lost 3% battery in just 5 minutes & I was in Settings (OS app)? Is this normal. My phone is just 3 weeks old.

Screen Brightness = ~18%
[Nexus 5 Original Android Development] eng.stk:
No you have something keeping cpu high (or radio wake locks) and it's draining in your setup.

In wifi my meter barely moves.
[Nexus 5 Original Android Development] wingoku:
I have checked wake locks via GSam Battery stats & screen is sucking more battery after Apps. The top sucking apps are System UI, Android System & Kernel. Signal strength is awesome on my phone.
[Nexus 5 Original Android Development] jwhyte:
Check with BBS or other for alarms and see how many times apps wake up your system. I average 0.2-0.3% per hour drain overnight WiFi off and cellular data on. Even dirty flashing can leave gremlins.
[Nexus 5 Original Android Development] wingoku:
It was clean flash. BTW what is your Idle time & SOT?

Hey guys, I want to increase performance of the phone, I don't mind a hit on battery but I just want raw performance. Can anyone share any settings they've found to do this using ukm and synapse?
[Nexus 5 Original Android Development] Gallardo994:
Governor "performance" should do the trick I think :D
[Nexus 5 Original Android Development] topgeardave:
I've tried that, in terms of normal usage I find it sluggish for some strange reason. Could be due to apps still not fully optimised for quad core. I'm currently using ondemand with hotplugging at 60%. Feels like the snappiest set up with battery not actually taking much of a big hit compared to how I thought it would be. Win win situation. I'll try out some more settings and let people know which kernel settings are best for real world usage :D
[Nexus 5 Original Android Development] andredn8:
Does this kernel works with NX ROM 7.2.4? because I have done a clean flash but until now I got 1 random reboot. I don't know it will continuously happens or what. Thanks
[Nexus 5 Original Android Development] hellsgod:
Please post a log next time. Otherwise nobody can tell you what happened.

hells
[Nexus 5 Original Android Development] reyfista11:
If you want performance just set minimal core online to 4. I'm using minimal 2 and it's pretty fast
[Nexus 5 Original Android Development] topgeardave:
I've tried that, seen no difference when having 2 as minimum and 1. Ondemand with 60% hotplug threshold and it's booming fast :) Also battery life difference compared to stock is the same for my heavy usage so I'm a happy bunny
[Nexus 5 Original Android Development] NeophyteGS2:
Ive used this kernel from day one using this ROM and i have never encountered any issues, and its by far the best kernel for battery life
[Nexus 5 Original Android Development] alen1901:
Last kmsg here. Got a soft reboot.

My setup:

- row scheduler 1024 read ahead

- ondemand gpu gov

- uv -50mv (which is really -25mv)

- temperature limit lowered to 60

How soft reboot happened:

- all was working normally, i just cleared all recents, opened chrome and pressed thumbnail to open g+, i saw phone freezed, pressed home button but nothing

- then i left it to be like that (thought eventually it will unfreeze)

- screen turned of after 3,4mins (even if my settings are set to 30sec)

- then i saw it soft rebooted

Sorry for not putting it on a pastebin but im traveling to Austria. ;)

After cruising on stock 5.0 and Franco kernel for a few weeks, I've finally moved to this awesome kernel and I can now say its by far the best of the best! Performance is unmatched, battery life phenomenal giving me 6h with normal use without games, default gamma by Piereligio makes it even better a new device out-of-the-box, I mean everything is just amazing. Currently my max CPU is 1.5 and 320 for GPU with 100mv global UV rock solid, everything else default. I urge everyone to try Code_Blue its mind bending kernel, kudos to dev! Cheers all! :good:
[Nexus 5 Original Android Development] SGT John Doe:
Just a quick question since i'm new to Nexus and Lollipop. Do i relly have to reflash my Rom if i change kernel? What's the worst scenario if i don't
[Nexus 5 Original Android Development] C0deFire:
I believe its chrome doing that, i have gotten the exact same issue as you twice just by using chrome tho.
[Nexus 5 Original Android Development] alen1901:
Im starting to think its related to that memory leak bug on lollipop because chrome uses a lot of RAM.

hi [MENTION=3873953]eng.stk[/MENTION] wanna ask, does r777 compatible with usb-otg mounting as usbdisk on lolipop 5.0.2 r1(LRX22G)? because i use simpleaosp and i need stickmount to mount my usb-otg. the rom in this link

http://xdaforums.com/google-nexus-5/development/rom-simpleaosp-t2933419

thanks.
[Nexus 5 Original Android Development] Steven 1:
You'll most likely run into some system errors like reboots and force closes. Nandroid in recovery before flashing the kernel and test for yourself. You might not run into any errors. Good luck
[Nexus 5 Original Android Development] eng.stk:
I don't know, maybe. I never liked Chrome, too resource hungry.

Yes, Code_Blue has usb automount in /storage/usbdisk
[Nexus 5 Original Android Development] antec123:
yes, i used terminus 13/12 it works fine. maybe from the rom isn't not supported. i will try to flash newest terminus again to see the difference, thanks anyway m8.
[Nexus 5 Original Android Development] grognaz:
so i flashed this kernel today to give it a try but there were some bt issues and i decided to restore the cwm backup that i made before flashing the kernel. however i am not able to boot anymore, the device is stuck in a bootloop.

why is this happening? why cant i get any of my backups booting anymore?
[Nexus 5 Original Android Development] topgeardave:
Could be due to cwm not being lollipop friendly, not seen a cwm build since lollipop released. Most people use TWRP these days. Try dirty flashing the rom on top and it should be fine again :)
[Nexus 5 Original Android Development] Dark_Eyes_:
Just came to thank [MENTION=3873953]eng.stk[/MENTION] for the amazing kernel. My battery life is incredible on deep sleep.

Keep up the good work and happy new year to you and everyone in here!
[Nexus 5 Original Android Development] grognaz:
i hate twrp, used it on my old nexus and if messed up the device badly. maybe its time to give it another go...

i tried dirty flashing and that caused a huge mess, somehow copies all data on the sdcard to 0/0/0 and causes unlimited force stops when the rom starts... this f ed up my device again... oh boy time for a clean installation. i hate it when i dont know what exactly caused this, because it will most likely happen again if i dont.\

oh yeah and not to forget its hiding my cwm backups again so i have to use some shell commands to get them back again...

but all this probably has nothing to do with this kernel but the rom and recovery so enough for the ranting.

happy new year:silly:

[Nexus 5 Original Android Development] SGT John Doe:

But is there no control app for this Kernel?
[Nexus 5 Original Android Development] drac0:

[Nexus 5 Original Android Development] NeophyteGS2:
Youll probably find that at first it will say device unsupported. To fix it, open up a terminal emulator app, type su, then type /system/etc/init.d/UKM and then reboot yoir device. Works everytime for me :)
[Nexus 5 Original Android Development] SGT John Doe:
I tried the method michaelz93 gave me http://xdaforums.com/android/software/zip-synapse-script-universal-kernel-t2736986

and it works just fine :) Only "problem" is that i can't overclock since there no higher options then stock. Not because i need it, but it would be fun to try.
[Nexus 5 Original Android Development] michaelz93:
I don't think you'll need to overclock, this kernel has the best balance for performance/battery needed....

Why is my LogCat full of: "touch_boost: failed to send: No such file or directory"

Every time i touch the screen the log get full of this...

How to disable it ? it's anoying when trying to find some apps bugs on the go...
[Nexus 5 Original Android Development] Haidary.T:
If I recall I think it is because this kernel does not use mpdecision. It instead uses a different hotplug. Is it absolutely normal and you should not worry about it.
[Nexus 5 Original Android Development] neopbm:
@ eng.stk or anyone with the knowlege

In the OP there is info about how to use f2fs with this kernel. Is it compatible with kk version or just lolippop ?

Trying to get a kk rom working with f2fs for data and cache in primary rom.

Thanks
[Nexus 5 Original Android Development] drac0:
Use the one specified for KK, I think its the r450 release, and nevermind the ROM cos its the kernel that mounts F2FS partitions. Just wipe and format your /data and /cache partitions to F2FS and then flash Code_Blue after it. It will recognize and mount your F2FS partitions without any problem.

If you want to save your data, there is a trick that [MENTION=5594433]dechronic[/MENTION] taught me. Just backup your current /data partition and then rename any EXT4 in the backup list names to F2FS. For example, if the data partition backup file is called DATA-EXT4-01-02-2015 rename it to DATA-F2FS-01-02-2015 and restore it right after you've finished with formatting your partition to F2FS. Then flash the Code_Blue kernel. No loss of your data nor settings! Cheers! :good:
[Nexus 5 Original Android Development] neopbm:
Tried that but it didn't work.

Maybe older kernel version is not compatible with f2fs?

Thanks for your answer anyway
[Nexus 5 Original Android Development] drac0:
Yes that could be the case, I'm not sure when did [MENTION=3873953]eng.stk[/MENTION] implemented F2FS commits inside kernel maybe we ask him? :D If those commits are there you just need to edit your kernels ramdisk so it can see your F2FS partitions. Out of curiosity have you tried to flash latest r777?
[Nexus 5 Original Android Development] neopbm:
I am using a kk rom and as far as i know builds after #450 are for lollipop so no, did not tried to flash 777

Code_Blue r793

All right crew!

New year, new build :highfive:

Just pushed new build r793, probably one of the last until I concentrate in my upcoming shamu.

I added some improvements to blu_active, load and freq fixes and improvements, energy management improvements, upstream patches to several subsystems like net work and so on.

There's a fix in installer to ROMs without battery saver support (like some CM builds out there and others), some RAMdisk improvements and sync with CM12 also.

Happy new year! :fingers-crossed:

Get involved, test, play, donate, help, contribute.

[Nexus 5 Original Android Development] eng.stk:
Nope, root works with some apps, others not.

superuser is still not ready, nothing to do with kernel. Use SuperSU.

No because you would need a permissive kernel and Code_Blue is not.

You can use f2fs in data and cache from the box
[Nexus 5 Original Android Development] exxpired:
That what I thought, I already have data and cache f2fs and system ext4. Just misread what the other guy wrote
[Nexus 5 Original Android Development] Berget:
well, that is a workaround dont realy fix the problem in the kernel dosit? ;)
[Nexus 5 Original Android Development] kekkopf:
I can't download the latest version, appears "download failed"
[Nexus 5 Original Android Development] drac0:
Yes system like system wide, not like /system partition, since Code_Blue is not a permissive kernel and really there is no true performance benefit of converting your /system partition to F2FS. Sorry my typo. But the updater-script has a very smart line for mounting your F2FS /data partition which is great if you ever need to write to that partition during system install. Anyway one of rare hammerhead kernels that is fully F2FS out-of-the-box ready. Cheers! :good:
[Nexus 5 Original Android Development] eng.stk:
What kernel issue? There's no kernel issue with either Superuser or SuperSu!

Either with r777 or r793 (and probably earlier versions also)

On CM12 you must go to developer settings and activate superuser.

ANy issues you have with superuser are from the app because it's still in development.
[Nexus 5 Original Android Development] Berget:
ooh stupid me, after flashing the kernel the rom had disabled that option. Thanks!

i can do conferm that the build in Root and the older versions of code_blue dont work together.

793 just gave me the best battery cycle I've ever had.

Cataclysm ROM.

Cubic, 128, cfq.

Multi core power saving 0, GPU Ondemand 450, UV 25mV.

Adaptive brightness on with slider about 1/3 from the left.

Sorry for bothering. I am using your kernel since a while and I have to say that it is awesome, but I have something to report: with latest CM12 build (mo976 20150104) your kernel breaks root access, the new built-in one with privacy guard. Flash SuperSu still allows to use this kernel.

Sorry for not posting logs or similar.

Thanks for pointing out possible tricks I could have used to produce those screen shots, but I also have better things to do with my time than try to trick XDA users into thinking I have better battery life than I actually do (why on earth would I want to do that?). Those screens are just after regular use for a day. I described my phone settings above. You didn't see user apps in the screens because I didn't scroll further down the battery stats page for another screenshot. If I knew I was going to be grilled I would have. I used mostly chrome, Play Books, Tapatalk, Carbon, a few texts and a short phone call, plus a few other apps sporadically. You'd expect apps like that to be lower in the list when you get really high screen on time exactly because by definition the screen is using relatively more battery compared to those apps.

I also have better things to do with my time than to justify my screenshots, so I won't say any more on the matter. I was impressed with the battery cycle so I wanted to share in this thread to show appreciation to the dev. You have a right to be sceptical but I think you were very rude.
