Ah I thought there is special setting for me :P

Anyway should this 3 options enabled or not? I saw this 3 settings in synapse what do they do?

Power Efficient Workqueues

Gentle Fair Sleepers

ArchPower

And what's a good GPU governor? :)
[Nexus 5 Android Development] rachanta:
I am discontinuing the kernel line that had that. Synapse describes briefly what they do. In the end you can decide what compromise you can make for what benefit. I would recommend not enabling. Ondemad the default gov is recommended.

This kernel on euphoria is fantastic, very smooth and good battery life. Great job OP.

CAF

Can this be used with CyanogenMod 12.1 nightlies for hammerhead CAF?
[Nexus 5 Android Development] rachanta:
Not caf, only 12.1. I use AICP which uses 12.1.
[Nexus 5 Android Development] oo0:
caf really needed. i bet, after hammerheadcaf release 60% would use it, not aosp.
[Nexus 5 Android Development] rachanta:
For some reason I could never build the CM12.1-caf base kernel successfully on my build platform. lol !
[Nexus 5 Android Development] reddvilzz:
I got this weird SOD with the latest build here is the screenshot.

I have no idea what do you needed to check it though since it is SOD
[Nexus 5 Android Development] rachanta:
You may need to reinstall along with ROM, or even wipe data. I have had no problem at all. Your theme could also be a problem.
[Nexus 5 Android Development] reddvilzz:
It is a cleaned installed Cataclysm rom with layers though. And the SOD problem pop out sometimes not always every time the phone sleeps.
[Nexus 5 Android Development] ianoob:
What are your settings? I'm on Cataclysm as well, have eliminated most of my issues by tweaking the LKM and changing to the N6 hotplugging

Edit:

I've also turned off fsync and raised my screen-off frequency to 1.5ghz
[Nexus 5 Android Development] CristianChavez:
Would you mind expanding on the nexus 6 hotplugging or maybe show a screenshot of your tweaked hotplugging settings?
[Nexus 5 Android Development] ianoob:
Change all the Runqueue Threshold Hotplug to 1, all the Runqueue Threshold Unplug to 0. Leave the setting to run on only 1 core during screen off checked.

Please note this is basically 4 cores except screen off and ymmv. More details are in the Cataclysm thread :)
[Nexus 5 Android Development] reddvilzz:
How's battery on that hotplugging? Since I kinda want to keep my phone cold enough in the mean time
[Nexus 5 Android Development] ianoob:
I stream a ton of music at work and never turn anything off, but I still get 2½-3½hrs of SOT.
[Nexus 5 Android Development] rachanta:
Can you post screen shots of your settings, so that i can if possible change default values of lmk in the code. BTW I am running the next release with a debased lmk upstream update and have set aggressive lmk though I actually never had any problem on the last few stable builds.

Also found workqueue updates as a source of instability. The main sign seems to be unstable min freq settings. If these settings don't survive reboots or get stuck at touch boost values we have problems.

Sorry if repost.. How to enable DT2W sir?
[Nexus 5 Android Development] Jiggs82:
Quick noobish question but can this kernel be flashed over a caf rom too or strictly aosp? Lol
[Nexus 5 Android Development] reddvilzz:
AOSP only so far I think.
[Nexus 5 Android Development] kingserpent:
It works on CM12 based ROMs like blisspop. I'm using it right now without any issue.
[Nexus 5 Android Development] reddvilzz:
That's because cm haven't gone to caf yet. Saw it in some posts I forgot where

Like all other custom kernels except a abandoned one this kernel starts to lag really bad after about 2 days.

And like in every other kernel thread i ask the dev of this kernel: are you interrested to fix this issue or are you ignoring this as all other devs have before you?
[Nexus 5 Android Development] cmdmilitia13:
Every ROM & kernel will lag after 2 days if u don't reboot the phone once in awhile imho.. If u reboot the phone does it still lag?
[Nexus 5 Android Development] reddvilzz:
Using it for almost a week and I don't see any lag coming at all. Probably your phone heating up? And causing the cpu frequencies to go lower

---------- Post added at 07:25 AM ---------- Previous post was at 07:24 AM ----------

[Nexus 5 Android Development] cmdmilitia13:
Flashed this & latest chroma ROM at around 12pm & gave it a full charge then took it off the charger.. Listened to about an hour of music,some Facebook,Instagram & XDA (of course lol),downloaded a few games (haven't played any yet),been texting all day.. Almost 3 hrs screen on time ain't that bad with my kind of usage.. No stutters, hiccups,lags,no random reboots.. Racer+chroma=buttery smooth goodness ?

Accidentally checked and found 3.4.107, so it needs to be included in next release

Feedback welcome, actually necessary ;)
[Nexus 5 Android Development] BiasedThunder:
Just flashed this over Chroma (yesterdays update) and it seems to be running great so far. I'm getting great scores on Vellamo and doing better than 13400 on quadrant. Its very snappy and responsive. As for the battery life, I cant say just yet since I've just flashed this tonight but I will update tomorrow after work. I have no way to charge my phone all day while working so if it lasts the whole day I will be impressed.

As for right now the way this kernel is running on with the rom I have combined it with I am very happy.
[Nexus 5 Android Development] grognaz:
This is not true, it does not happen with the stock kernel, nor with hybrid v3.

Its a joke that i offer to help find a problem with the kernel and nobody even takes a look at the logs.

Hey [MENTION=1863016]rachanta[/MENTION] , I would like to give your kernel a spin, but my cache and data partitions are already formatted to F2FS. Is there a patch file to edit my ramdisk that will let the kernel to enforcing?

Thanks bro !
[Nexus 5 Android Development] rachanta:

[Nexus 5 Android Development] donnabelmartie:
It's my first time to use this kernel and it's really smooth! However, the wake settings don't stick after reboot? No apps used, just edited in es file explorer. Thanks!
[Nexus 5 Android Development] Dark_Eyes_:
Don't want to bother you but it's permissive. Is there one for enforcing? I recall Chet having one as well for enforcing...

Thanks!
[Nexus 5 Android Development] rachanta:
You can find the links from Chet's thread. I only downloaded the permissive patch added to my utilities to run all f2fs for a few weeks. In my case, the system folder would always revert to ext4. Only data and cache remained f2fs.

[Nexus 5 Android Development] pianistaPL:
Should I install it before or after Racer kernel?
[Nexus 5 Android Development] rachanta:
Any time, but I think it is required for every ROM install.
[Nexus 5 Android Development] donnabelmartie:
For some reason I can't install kernel auditor last night, it does nothing when I tap install. Enabled root first then assumed you have the same values with elemental x. Luckily, you have. Sweep to wake up = 4. Sweep to sleep left = 2. I'm on team ub rom. 5.1.1 r_1
[Nexus 5 Android Development] rachanta:
You can also try Kernel tweaker assuming you want to use a free kernel app.

If Kernel Adiutor is not getting installed, there could then be other things wrong with your phone.

May be it is time you did a data wipe and install everything clean. If that does not solve your problem, you may need to start all over again from factory image installation (your internal sd card getting wiped in the process).

Successfully installed caf, and built a basic cm-12.1-caf kernel for it.

Does anybody know any caf kernel hammerhead or any other device that has dt2w, s2w?
[Nexus 5 Android Development] reddvilzz:
I think the last kernel from caf I know is neobuddy's kernel which is discontinued now
[Nexus 5 Android Development] rachanta:
I checked that source, there's no s2w, dt2w. I have built a working caf kernel with GCC 4.9.3 linaro cortex A15, but its bare bones. No racer features.
[Nexus 5 Android Development] reddvilzz:
Well than I don't know any caf kernels for lollipop other than that.
[Nexus 5 Android Development] ianoob:
I'm not sure if the bug is in the Google launcher or in the kernel, but I found one. If I use Synapse to allow all cores during screen-off, I get a SOD on 1st boot. If I change the settings and don't reboot, my launcher FCs. I can pull a log if you want?
[Nexus 5 Android Development] rachanta:
Confirmed. I'll work on it.

Edit: [MENTION=3580970]ianoob[/MENTION] I am not sure if this is a bug, because of the warning that kcontrol gives me. I need to check other kernels. Do you have any information about any other kernel's behaviour?

I have tried a build with exactly the same code as flar2 in msm-sleeper and cpufreq. This bug, if it is one, is not going away easily it seems. And it has put the brakes on my trials with caf.
[Nexus 5 Android Development] Assa551N:
Is it compatible with caf?
[Nexus 5 Android Development] ianoob:
I have been using your kernel exclusively for a couple of months, I don't have any data that would be useful at the moment.

[Nexus 5 Android Development] reddvilzz:
Been using it till now :D
[Nexus 5 Android Development] rachanta:
Noooo. The SOD with "single core on screen off disabled" problem this still there.

Edit:

Checked out

Hellscore that has elementalx msm-sleeper and msm_mpdecision (bricked) - same problem

Uber - no msm-sleeper, has msm_mpdecision (bricked) - no problem

I can deduce that elementalx msm-sleeper needs single core on when screen off - for no SOD. A difficult choice to make, considering that this is the default as well as recommended setting.
[Nexus 5 Android Development] ianoob:
Edit: Derp derp, it's early in the morning yet lol
[Nexus 5 Android Development] rachanta:
With Elementalx (flar2), I could not find any hotplug settings in Synapse or KControl, but there was no SOD so I dont know if single core during screen off was enabled or disabled by deafult.

RACER_016_20140424

If touch boost is enabled, Single core when screen off can be disabled. You may not get any SOD. I am still testing this setting, no problems for a few minutes at least.
[Nexus 5 Android Development] montbazon:
There is no caf kernel with wake option. I heard that has trouble with CAF MDSS.

Have you plan to build racer caf kernel??
[Nexus 5 Android Development] rachanta:
I have built a basic cm-12.1-caf kernel. There is a mako implementation by [MENTION=4316709]savoca[/MENTION] that doesn't use mdss. It uses lge_input_core. I am trying to port it to N5 with no success so far. I have asked savoca for help.
[Nexus 5 Android Development] montbazon:
Good morning, rachanta.

I understand. I just saw that information in chaos thread by [MENTION=3795148]neobuddy89[/MENTION]

Anyway, your support is really appreciate!!

[MENTION=1863016]rachanta[/MENTION] i see that you build a CAF kernel...is it public? It's nice to see that a caf custom kernel it's in the works :)

EDIT: RACER_016_20140424

"If touch boost is enabled, Single core when screen off can be disabled. You may not get any SOD. I am still testing this setting, no problems for a few minutes at least." The 24th April build is CAF? Because i noticed that single core screen off causes SOD on caf roms...thanks in advance for the answer..
[Nexus 5 Android Development] rachanta:
No caf kernel as yet for download. All kernels are AOSP/CM so far. I have a private build of CM-12.1-CAF that works perfectly, but it has no custom features.
[Nexus 5 Android Development] FunkyRasta:
I'm on a AOSP ROM , cataclysm, yet I had two SODs so it isn't CAF specific ;)
[Nexus 5 Android Development] SedyBenoitPeace:
It depends from the kernel.. I use uber kernel and cataclysm and I never had a sod :)
[Nexus 5 Android Development] rachanta:
Pl go back a few posts to know more about SOD in some kernels. If you enable single core when screen off, you should have no SOD.
[Nexus 5 Android Development] ianoob:
After 3 days, I'm still loving the 4/24 release. I stand by my test 2 comments, this is the best my phone has ever ran Lollipop.
[Nexus 5 Android Development] SedyBenoitPeace:

Wake controls working on AICP hammerheadcaf:

RACER_CAF Hammehead Kernel with wake controls:

https://www.androidfilehost.com/?fid=23991606952593169

No luck with kexec hardboot so far. This will work only as secondary and not as primary in multirom.

The boot splash is missing, and you will encounter a black screen after Google logo. Wait for some time. The screen will light up once you press power key after 2-3 minutes.﻿
[Nexus 5 Android Development] reddvilzz:
Finally CAF custom kernel. Does it have all the goodness from AOSP kernel? Just a quick question about the CAF AICP does it need to use CAF TWRP as well?
[Nexus 5 Android Development] rachanta:
Usual TWRP will do. Racer caf has only wake controls as a custom feature. It will work only on secondary ROM.
[Nexus 5 Android Development] reddvilzz:
Ah okay, I'll wait for more features on the racer caf before moving on to caf I guess. Can't survive without all the aosp goodness but in the same time really wanted to try caf based rom
[Nexus 5 Android Development] SedyBenoitPeace:
Please (in future) consider also to put fast charge on CAF Kernel (of course if it's possible), when the kernel will work also on primary i will give it a try...thanks for your work mate!
[Nexus 5 Android Development] ianoob:
So far so good, I'm charged back up and am testing multiple cores while screen off. Thank you!

Edit:

Was fine with music playing on my desk, but SOD after I put my phone in my pocket for a bit. No logs due to a hard boot
[Nexus 5 Android Development] rachanta:
I started having reboots after I installed a different TWRP to try my caf kernel as primary. I have got the original TWRP back, but the problems continued - mainly reboot after a phone call. I am a doing a clean install (data, cache, dalvik) with latest Slim Gapps to be sure.

Edit:

I think that the max screen off freq interface code that Chet has removed from uber could be the source of the problems. I'll remove it in the next test.

Is there a reason why all cores must be online at all times with the caf build,
[Nexus 5 Android Development] rachanta:
I haven't checked if it is necessary. Is it unstable otherwise?
[Nexus 5 Android Development] willybarca:
not unstable but battery life is worse then stock caf rom,
[Nexus 5 Android Development] rachanta:
[MENTION=2482202]willybarca[/MENTION]

There is no hotplug that can be set to switch on or off the cores in both the stock as well as racer_caf. The one battery draining feature is wake controls which keep the phone listening for wake actions even when the phone sleeps. Pl try these two just in case you havent as yet:

Set an appropriate (2-5 minutes) wake time out in Wake controls. Thsi will disable wake controls after the time out period

Enable power-key suspend
[Nexus 5 Android Development] willybarca:
will u add hotplugs in the future

I've tried looking on google but all I could find were explainations of the differences between various CPU governors, or more in depth guides for similar things or different devices. I'm currently rynning Cyanogenmod 11 with the 4.4.2 version of Android

I'm looking at the Smartass 2 governor,

because I like its idea of having ideal frequencies, and am currently using the PegasusQ governor, but I dont know a lot about my current governor. Is there a benefit i can get from swapping?

A friend had sync turned off in his s4. I exported his contacts to microsd using contacts-export to sd. Now when i tried to import the vcf file to the s5, i can not figure out how to. The s4 has been factory reset and sold so there is no way to sync to google servers. Jow can i transfer the contacts.vcf to the s5?
[Galaxy S 5 Q&A, Help & Troubleshooting] calinormy:
I guess you could import vcf to Google on a computer then synchronize with S5.

You can do it on the S5. Open contacts. Go to the settings menu(top right 3 dots). Go to settings, then you will get a screen that says Call and Contacts. Open Contacts and you will see Import/export option
