New nightly release:

Chaos-Kernel_v12.0-[05-04]-[21-00]

* Add support for CM11's new feature in latest nightly - Color Calibration
[Nexus 5 Original Android Development] neobuddy89:
Scores posted above are for performances (should reflect to some extent) and should not be concluded for battery life.

My current config:

Default Profile + Intelliactive (both screen on/off) + Intelli Hotplug + KSM Enabled + TrueRGB v7 Color Profile + Quality sound Profile

I am not recommending any defaults; just letting you know my liking for now. :)

Battery life WITH best performance... read
[Nexus 5 Original Android Development] daniel84cs:
Once again, congratulations for your kernel and application are months that I used the Paranoid with Franco kernel I have to admit that your work was superb. This kernel combined with the convenient application profiles is what I wanted, I asked many times to Franco to introduce customizable profiles in its application (albeit for a fee) but he never did. Thank you for your continuous work, the only thing I would add (if possible) the possibility of reducing the voltage of frequency 300 mhz or even maybe create some tables UV ready style Abyss kernel.

Just thought I'd tell you, uv makes no difference whatsoever. I've used 300mhz at 800mv(pvs0) and at 680mv(Franco kernel) no difference at all. With aggressive uv you run the risk of messing up your cpu over long term use and I've also read that it can screw up your emmc as well creating block errors.
[Nexus 5 Original Android Development] paychex:
The time it would take to do that probably isn't in the normal life of a phone. But aggressive UV'ing you run the risk of it being counter-productive. If you UV so much that it requires extra CPU cycles to accomplish a task you defeated the purpose.
[Nexus 5 Original Android Development] topgeardave:
Thought I'd share my battery performance. 5h SOT over 12 hours with mixed wifi and 4G. Using Cyanogenmod hotplug at 1.5ghz. I've attached my results:

I would like to share my observations with different hotplugging settings with intellidemand governor at 2.3ghz.

MSM Hotplug: This is the most aggressive hotplugging implementation of the 4. This is battery hogging but you do get a lot of raw performance as frequencies on the cores get on the high side.

Alucard: The second most aggressive hotplugging I've seen under load. However it does hotplug linearly unlike Msm which fires up random cores even if the screen is static. It seems like this is the best for gaming and battery.

Intelliplug: Not very aggressive under load, usually keeps two cores on then others turn on depending on the load. Quite good for performance/battery.

Eco mode is quite bad because both cpus are always maxed out at 2200mhz and never go down. Looks like because of the two missing cores it takes longer to do the tasks and drains battery. To get better battery I recommend underclocking to 1.5/1.72GHz and not turn eco mode on.

Cyanogenmod default: one core is active all the time then others switch on linearly depending on load. Looks like it's the most battery friendly one but performance suffers.

[MENTION=3795148]neobuddy89[/MENTION] Thank you for getting the audio glitches all straightened out. I would like to report another issue. I was watching a video on YouTube and the video driver crashed, and so I restarted and it worked. I created a last kmsg if it would be helpful?

Hi bro, I'm sorry for my noob question, I'm using 11.1 stable version so where can I find Intelli Hotplug?

[Nexus 5 Original Android Development] topgeardave:
Just an update, thought I'd try conservative governor for screen on. It's actually really reserved in terms of scaling up the frequency. Anyone who wants raw battery life should use conservative. I'll post a couple of screenshots in a couple of hours to see how well it really fares over the course of a day
[Nexus 5 Original Android Development] antypas:
Well, everything depends on settings. This is Neobuddy's tweaked MSM Hotplug.

Neobuddy tweaked MSM Hotplug to have instant performance and made it easier to online cores. This obviously has a severe impact on battery life.

By default (or if tweaked towards the other end) it is a great hotplug driver for battery also. I have implemented it in a custom kernel I built for personal use and made higher the load thresholds and it has good battery life and performance at the same time.

Look at this commit:

https://github.com/neobuddy89/hammerhead_kernel_caf/commit/f66998176eba2ddfd3c50259a9fddba99977657e

at line 140.
[Nexus 5 Original Android Development] neobuddy89:
If all techniques start saving battery, there won't be much use of high performance device. ;)

I may provide controls in NXTweaks to let users control these loads, so that, they can configure accordingly.
[Nexus 5 Original Android Development] antypas:
It's not only a matter of battery savings. Thermal throttling comes into play much easier with aggressive settings, so it is a matter of performance too.

I set thermal throttle point to 70C, played Plants vs Zombies 2 for 10 minutes and to my surprise (I checked in Trickster) I was throttled down to 1190Mhz.

Maybe a setting where the 3rd core would come online harder and the 4th only when absolutely necessary is more appropriate for our device.

But, on the other hand it is a good thing you provided all these hotplug drivers so that anyone can choose to his liking.

Conservative is great with hot plugging. Just wish I could change the tunables for the governor in the app. [MENTION=3795148]neobuddy89[/MENTION], and chance you could add that into the app?
[Nexus 5 Original Android Development] topgeardave:
Have you tried the Cyanogenmod hotplug? For me thats the least aggressive one of all of them stock
[Nexus 5 Original Android Development] paychex:
I'm using Alucard because you can set the number of cores when the screen is off. Noplugging beats hotplugging for battery saving! Even with one core, conservative, vr, and the lowest screen off frequency I can choose, no audio shudders while streaming Google Music
[Nexus 5 Original Android Development] topgeardave:
How do you disable hotplugging? Unless Alucard is just for screen off only?

[Nexus 5 Original Android Development] trungquan_it:
I've been using latest nightly for about 2 days and I've got many random reboot.

Running on AICP with default profile, I only changes governor to conservative, alucard hotplug, sound control to quality, that's all.

I think I should back to 11.1, which is much better for me and wait for stable 12.0.
[Nexus 5 Original Android Development] Primokorn:
Not a single random reboot since yesterday with AOKP.

Intelliactive (screen on/off) + Intelli Hotplug + FIOPS

[MENTION=3795148]neobuddy89[/MENTION] every once in awhile I notice the S2W times out on me. I'm UV'ed 20 across the board. Alucard with one core screen off. Would the aggressive settings be the cause? It's random and hard to reproduce, but if I can would you need logs to investigate?
[Nexus 5 Original Android Development] alexeius:
Got my nexus a week ago, and today I have experienced best battery life for me with 12.0 and cm11 04/05 build. Intelli hotplug, intelliactive/conservative(screen off), UC to 1.7 ghz. Thanks for this awesome kernel. 12 hours, 4:50 SOT

Left this kernel due to love with SlimKat and LiquidSmooth. Last day while trying Resurrection Remix, flashed 11.1 stable release of this Kernel and I'm still in shock on having such a great battery life even on first charge. It's really hard to believe this much insane figures, but with my moderate usage of around 1 hour voice call, apps installation after fresh ROM flash, 50 mins of screen on time, from about last 8 hours, it is still on 86%. Also did I mentioned 0.4%/hr battery loss while at sleep. :D. Superb work Dev. Thanks again.

[Nexus 5 Original Android Development] mo976:
From my observations it seems that the Cm hotplug is the most stable and very battery friendly, inteliplug is better on the battery but causes occasional UI freezes and such sometimes resulting in the need to force reboot even when eco mode was disabled. Maybe something needs to be adjusted or cleaned up in the code?

I flashed this kernel yesterday and the performance has been amazing since then..I am having just one issue..If I switch to "battery" profile, I am getting random reboots..my phone rebooted twice within a span of half hour..so do I need to change anything?..I am on default profile now..

I was on default profile and the phone had a random reboot and then went into bootloop ..I cleared the dalvik and cache and rebooted but to no avail..

Then I reflashed my ROM but to no avail.. So I have formatted my data and system and restored a backup that I created from TWRP a few days ago..Now it's fine..

nope. had lots of reboots a couple of weeks ago. but when you fixed it - there were no reboots on any other rom i've tried. only dt2w issue, everything else works stable, fast and battery friendly with cm11 and pacman.

cm11 latest nightlies definately need twrp 2.7.0.0. also, the bootloader update should be applied to be sure.

My battery today looks like its gonna be around 3.5 hours screen time with 20 hours usage (my night battery saver might make it up to 28 if im lucky) And this was all with an 9 hour wake lock from the phone app that I fixed so it could probably be around 4-4.5 hours screen on time tomorrow.

Underclocked: 1.7 gHz

Undervolted: 20 Hz

Hotpluging: Cyanogen

Wifi/3g (2g when wifi is connected for when screen is off for more than 2 minutes)

phone app wakelock 8h 41m 22s (caused by proximity sensor not turning off after an incoming call)

Listened to music for 2 hours

On the phone for 1 hour

phone soft reboots upon Bluetooth connect

So my phone freezes upon any new Bluetooth connect. As soon as it freezes if I hold power and restart the phone it boots up again and connects to my Bluetooth in my car just fine but only after the cycle of freeze, reboot, reconnect.

I'm using a nexus 5 with latest cm11 nightly, and chaos kernel. I tried the master 11.1 release as well as latest nightly kernel. It happens on both.

When I switch kernels to elemental I no longer get this problem, however I love the battery savings on this kernel.

Attached is the last message log pulled from the nix app. I'm hoping it can help someone deduce and help solve my issue?

Thanks guys!

[MENTION=3795148]neobuddy89[/MENTION] Your kernel has also been flawed by a little bug in the Kcal RGB mod. It multiplied the colour channels with 256/255. RGB-255 was this way lost and the colour control parameters acted differently. Please update the code according to this fix by Faux and me:

[Nexus 5 Original Android Development] neobuddy89:
Thanks for the log, I will check as soon as I reach home.

I saw this patch earlier morning. I really appreciate your efforts but am little confused because CM11 mods max default calibration to 83% in their control and provides user interface accordingly. Is that correct? If yes, won't this patch flaw CM11 slider control?

Will check more once I am home. Kudos, again.

I'll have to flash your kernel and CM to see what you are talking about;) It's in the CM Rom right?

I am not getting any such wakelock from dialer. Are you on latest nightly? How are you checking it for sensor?
[Nexus 5 Original Android Development] Williamsss:
Well i already fixed it =] It was caused by either the smart dial (hold to face to call when dialing) or the flip to silence. I dont have it anymore. That was just a disclaimer for why i only got 3.5 hours screen on time with 22 hours off battery
[Nexus 5 Original Android Development] yorici:
Hi, installed your kernel and latest CM rom. What CM11 slider are you exactly talking about?

Btw your kernel has not yet been affected. I looked at your commits and saw this commit. Therefore I thought your kernel had been affected, but you haven't enrolled an update including it yet.

If the CM11 mods interfere with the patch, they will with the KCAL Control mod too. So if you were able to use the CM11 slider with KCAL, you will be fine with the patch. The patch just corrects KCAL.
[Nexus 5 Original Android Development] neobuddy89:
I am talking about sliders they provide in settings.

I have only one commit for kcal driver which is same as that of CM11.

Yes the patch will influence the cm11 sliders then, but the cm11 are also flawed then. I don't understand why you say the max default is 83% when the sliders range from 0 to 100% though :s But I can assure you the CM11 sliders need patching too!
