Try setting CPU Idle / Settings using Faux Clock app. I can see at least one core going offline briefly in Trickster MOD. I don't know if any core is supposed to switch off completely. I also set multicore power saving to aggressive (2).

CPU Hotplug (not implemented) is required for full control on cores.

[Nexus 5 Android Development] socioteq:
When I change the scheduler or governor my phone will reboot, go to the Google splash and then shut off. As long as I don't change any settings, the kernel works, but as soon as I change anything the phone exhibits this behavior.

The ROM I'm using is AICP 9/7 , it was fully booted and set up with their stock kernel.

EDIT: I also noticed that I cannot boot to recovery without the micro usb being plugged in (after the ROM starts exhibiting the reboot/power off after the Google splash).

Is there anything that I may have forgotten here?
[Nexus 5 Android Development] rachanta:
Clean data of built in kernel adiutor, install ukm use synapse. Clean data of all kernel apps and reinstall ukm, every time the kernel is updated.

The Caf kernel may reboot once or twice, but settles down. I have had no sod or reboot the last 12 odd hours and I have changed governor and scheduler more than once. I am on the latest AICP hammerheadcaf ROM. Over clocking and undervolting may cause reboots. The caf kernel is not as stable as racer-aosp and racer-6.

You can also install cm-12.1-caf stock kernel once to clear up junk settings. https://www.androidfilehost.com/?fid=23991606952606084

The kernel here is my caf stock built from old cm-12.1-caf stock source.

I have flashed, wiped, reflashed, cleared data, in every possible combination and am still unable to boot your latest 9/10 kernel.

I am flashing in this order (what is your flash order?):

1) ROM (AICP hammerheadcaf 9/9)

2) Gapps (DU_TBO_GAPPS 8/5)

3) SuperSU 2.46

reboot

Again, the system will boot in this order:

1) Google splash for a few seconds

2) Power off

2a) Won't boot to recovery unless I have the power cord plugged in while holding Power+VolDown buttons

LOLLIPOP CAF

RACER_CAF_054_20150911

https://www.androidfilehost.com/?fid=24052804347812859

RACER_CAF_SPLASH_014_20150911

https://www.androidfilehost.com/?fid=24052804347812850

This build has boot animation but no wake controls

Follow these steps:

Charge the phone to full

Remove power chord

Enter recovery (if it doesnt enter recovery, your recovery could be corrupt. Reinstall latest TWRP recovery image from bootloader)

Clean install hammerheadcaf + gapps - wipe data, dalvik and cache (sorry but you need to wipe data once)

Install su

Please boot once with https://www.androidfilehost.com/?fid=23991606952606084 after

Check whether your recovery and other issues are solved

Go to recovery

Now install racer_caf

Install UKM

Boot (In case of CAF (not splash), you will not get any boot animation splash after Google logo. Wait till phoen sleeps

Set the kernel (dont oc/uv for now)

If none of the above work, you may need to install factory image again and repeat the whole process. This is because your bootloader and official recovery may be corrupted. Install TWRP latest image and check if recovery is working

[Nexus 5 Android Development] rachanta:
Read http://xdaforums.com/showpost.php?p=62769794&postcount=2587

And please read OP

Anyway...

Reinstall your ROM

Then RACER_CAF_SPLASH, UKM

After that if you really want wake controls install RACER_CAF and then UKM.

Another way to clean up junk settings is to install CAF_STOCK Kernel and UKM

With CAF build, you may get one or two reboots in the beginning

Do not overclock or undervolt

In case CM-12.1-CAF has LVY48F / 5.1.1_r18 source merged, you may need to clean install (data, cache, dalvik) like I had to when I installed the latest AICP hammerheadcaf which is based on CM-12.1-CAF

I got oc/uv, hotplugs and msm limiter code from [MENTION=3795148]neobuddy89[/MENTION], from his discontinued hammerheadcaf kernel. That's almost the only caf source / kernel with oc/uv. I don't know if it can be improved.

[Nexus 5 Android Development] xeraphael:
rachanta, unfortunately I still seem to be facing the same problem of the min freq resetting itself to 96 MHz periodically.

It looks like I'm the one facing this problem, but I was wondering if there's any data I can provide that might help you find out what's causing it? Your kernel is perfect otherwise and I would really love to make it work, but no pressure - it's just the nature of the beast that not everything will work for everyone, I guess.

EDIT: using Kernel Adiutor, CM12.1, and I'm trying to set min freq to 422 MHz. The setting sticks for a while, but resets to 96 MHz a few minutes after screen off. Kernel Adiutor sets min freq correctly upon reboot, but several minutes of screen off causes the problem to reappear again. Using msm-mpdecision for hotplug, if it matters.
[Nexus 5 Android Development] rachanta:
[MENTION=4485711]xeraphael[/MENTION]

All racer kernels have msm-limiter that locks set frequencies. This can be enabled through synapse. Please wipe all kernel app data, install ukm 3.8.1, reinstall racer. Install synapse and set everything and report please.
[Nexus 5 Android Development] xeraphael:
Is it possible to configure msm-limiter via the command line or script instead? I'll flash UKM if I have to, but not unless I have to lol.

Does msm-limiter have to be enabled or disabled for 422 MHz min freq to stick?
[Nexus 5 Android Development] rachanta:
You have to, unless you can make the script. Synapse is almost mandatory with racer.
[Nexus 5 Android Development] xeraphael:
I should be able to write the scripts myself, but I can't find the path for the msm-limiter files. Could you tell me where they are.

EDIT: Found it, testing now...

EDIT 2: It works, huzzah! Thanks for the tip about msm_limiter, I would never have figured out what was going on otherwise lol.
[Nexus 5 Android Development] rachanta:
should be sys/kernel/msm-limiter

Edit:

You might want to share the script. I can link the post from OP with due credit to you.
[Nexus 5 Android Development] xeraphael:
It's just a simple "echo 0 > /sys/kernel/msm_limiter/limiter_enabled" to let Kernel Adiutor do its job without getting messed around with by msm_limiter. Not sure if its worth linking to.
[Nexus 5 Android Development] rachanta:
More elaborate, to make useful.

What file does the script go into. The steps you write could be used as general guide for making a kernel setting script. Thanks for keeping faith anyway.[emoji106]

[MENTION=1863016]rachanta[/MENTION] , I wanted to let you know that I did end up with everything working finally. My errors came from assumptions regarding how the kernel works. I assumed that I would need to wipe and have Android re-optimize all apps before the system boots. This was the wrong way to approach it. It was more simple than that. What I did to get it working is simply flash, then flash UKM and reboot. I'm writing to you from within Android now, so all is working well. It's toi bad intellidemand isn't working. Intellidemand combined with ZEN gave me phenomenal battery results that I hope to replicate in the future with this kernel. Keep up the great work!

Hi,

Just a quick question. I've just started to use this kernel and flashed M-PREVIEW 3: RACER_6_006_20150923 on my nexus 5 using TWPR, all installed fine.

However I would like to use the synapse app. This seems a little bit more difficult. First I got the no uci detected messages, flashing ukm scipt fixed that. However now I'm seeing another error, device not supported - slivelabel has failed both under ukm and AK kernel.

I didn't install ak kernel since it's nowhere mentioned. Do I need to? And if so can someone point me to the correct file?

All help much appreciated!

[Nexus 5 Android Development] rachanta:
Try to clear synapse data, reinstall ukm and then racer_6 again. Synapse works well with same combo for me. Its better to use Google's m preview three image in case you are using a repacked zip.
[Nexus 5 Android Development] Nevareht:
Thanks for your quick reply. I'm using stock google M developer preview 3

Is there a certain order in which to flash all these. I was thinking first racer_6, then ukm, then synapse. Maybe it doesn't matter.

Also I've found 2 versions of ukm.... ukm3.8.1 and ukm 3.8.4.0_special_ed. Which one should I flash?

best regards,

[Nexus 5 Android Development] rachanta:

Okay it was due to the version of ukm. I now reflashed racer and ukm3.8.1 and reinstalled synapse, all works well.
