Samsung DVFS and my custom clock settings. - Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti

Just reading up on Samsungs DVFS implementation. If I run custom clock settings and guvnors, does the DVFS still take priority?
I'm currently going through a major refresh of my tablet and am trying to establish what I should and should not be including.
I'll be running Civ's flexbeam and SphereXtreme but couldn't see any reference to DVFS on those threads.

I used the same setup... found stock with minimal mods to work just as good and have better capabilities with SD card and being OTA compliant for updates as well. I also had tested the DVFS disable with the the mods done in Civato's rom and kernel. No issues, both with his setup and my setup, and in stock rom as well.
Speed improvement was not too well missed.
I use the pro version of TweakterMod on the OEM ROM only to double the read ahead buffer for best speed with 633x SD cards.
Later on when developing gets better for a truly compatible Samsung kernel, I can use my pro version to its capabilities.
I have a few replies on battery consumption and workarounds along with a few threads as well for both SD and power battery issues.

FAQ
How do i change voltage? - Use the latest version of setcpu, leantweaks, cputuner, or your ROM's built-in tools.
Do i need to wipe dalvik/cache? - in general there's no need, but it doesn't hurt so if you have time go ahead. Posted Image I don't wipe.
​Can we OC higher or add more frequency slots? - You can find the extra slots in my experimental versions.
​Will this work on GSM gnexus as well? - It should. I don't have a GSM phone to test so let me know if it stops working.
What is interactiveX V2? Read this post and thttp://rootzwiki.com/topic/13092-kernel-leankernel-minimalistic-kernel-120-123111/page__view__findpost__p__342571
Are you getting Screen-Off/Sleep-Of Death (SOD), general instability, or unusual battery drain?
Before you post here (especially if you're running the experimental version), try the following steps in order:
0) dude, disable screen-off profiles if you're running interactiveX.
1) If you're running the experimental version, do you have 180mhz/230mhz and/or 1.42ghz slots enabled? If so disable them both!
2) If the above doesn't help, do you have custom undervolting enabled? If so disable it! (keep in mind that the kernel is already undervolted by default).
3) If the above doesn't help, are you using interactiveX or hotplug governors? If so change to interactive.
4) If the above doesn't help then you should not be running the experimental version. Install the stable version and try both interactiveX and interactive without custom undervolting.
If you're still getting SOD with stable/interactive, report it here.
What about call-recording? - First the app needs to support Galaxy Nexus. Find out if it does and then find out from the author of the app what kernel changes are required and let me know.
Should i set up screen-off profile? - ICS kernels have built-in screen-off profile for all governors at 700mhz. So you don't need it unless you want to set it lower than 700mhz. In general there isn't a whole lot to gain by setting it lower.
Hotplug vs interactiveX? - Read this post. HotplugX vs interactiveX
What is zram and why do i need it?
zram basically takes a portion of your RAM (10% using my script) and turns it into a compressed swap device. So in layman's terms you're extending the size of your memory (potentially from ~700mb to close to 1000mb depending on the compression ratio).
To answer the 2nd question, no you don't really need it but if used properly (using custom LK zram script) it could help you in two different ways:
1) Android OS is based on Linux OS and the OS will try to use a growing portion of your RAM for file and inode caches and if you keep your phone up without rebooting after a while you may notice things getting a little sluggish. That's because the OS is not doing a good job in dropping the caches and freeing up memory for the apps.
2) more RAM and tweaked minfree (also handled by custom LK script) could potentially allow your apps to stay in memory longer (this may or may not be desirable based on your preference of course).
In conclusion, I'd say if you're curious it doesn't hurt to try. To revert, just type "zram disable".
What's the low-down on the GPU OC?
My kernel's GPU is now set to stock 307Mhz by default. You can adjust that by using Variable GPU OC (see a separate FAQ entry below).
When you go from say 307 to 512Mhz, you will not experience near double performance increase. Due to the factors outside the GPU module (ie. memory bandwidth limitation), you can't truly OC the GPU. In fact, most people can't tell the difference between 307, 384 and 512. Nenamark2 will roughly give you the following scores: 307/25fps, 384/28fps, and 512/31fps.
Some of you have seen the note from Colin, the Google kernel engineer, not to OC the GPU because using the OV_UV voltage slot will drain the battery. My kernel uses the same voltage for both OV and OV_UV slots. So there's no danger of battery drain there.
Why are the IO benchmark test scores lower than another kernel?
Some of the kernels out there have fsync disabled to increase benchmark scores. I believe that is unsafe and could cause data corruption. I do have hooks in my kernel to disable it but I don't use it.
In real world there will not be any user perceivable difference whether you have fsync enabled or disabled.
Is there a way to tune hotplug via sysfs?
yes. Advanced users only!
My phone doesn't seem to be deep-sleeping, what gives?
(assuming you checked in the right place like cpuspy) In terms of deep-sleep, there's not a whole lot going on in the kernel. It works or it doesn't - and I can assure you that I test every release (well almost every release) for deep-sleep before I release.
19 out of 20 times it's either 1) some sort of background process that's preventing your phone from going into deepsleep, or 2) something's misconfigured in your ROM, or both. Also connecting to USB will prevent phone from going into deepsleep.
I'm having unusual battery drain - help!
First of all, our gnex has very poor battery life while in active use. It's downright horrible while screen is on - screen is definitely the main culprit and there's not a whole lot I can do about that.
Custom undervolting can help or can hurt. This is mainly due to SmartReflex (class1.5) which auto-calibrates the ideal voltages for you. In fact, with SR you don't really need to use the custom undervolting feature for frequencies other than the 2 lowest. It does a great job calibrating higher frequencies. I personally don't touch it.
The "notrim" versions are an exception because I had to disable SR1.5 for the trim override to work. There's no auto-calibration going on there. Feel free to mess with custom undervolting on the notrim versions.
Now, if you've already accepted the horrible battery life while screen is on, but have questions about battery drain while idle - read the next question.
I'm having unusual battery drain while screen is off, or phone is sleeping - help!
First, let's find out if you're phone is going into deep-sleep. Install CPUSpy, unplug phone, turn off screen, and leave the phone alone for 5-10min. Turn the screen back on, launch CPUSpy, and see if you see an active entry for Deep Sleep. If so congratulations - read on.
If you've determined that your phone is not entering deepsleep by using the above method, read my entry above that says "My phone doesn't seem to be deep-sleeping". I've heard that removing SDM.apk helps as well as rebooting the phone. Also try turning your bluetooth on and off, and launching camera app and closing it.
If you've determined that your phone is entering deepsleep fine but still feel like battery drains, read the next question.
I'm having unusual battery drain while phone is in deep-sleep - help!
First make sure you are absolutely positive that deep sleep is working (read the previous question).
While on my kernel *and* connected to Wifi, you shouldn't drain more than 1% battery per hour *average* while in deep sleep (based on 5-8 hour continuous deep sleep). With wifi turned-off, my guess is probably no more than 1-3% per hour, depending on signal strength.
tip 1: If above is not happening for you, first charge the phone all the way and reboot. Let things settle a bit - give it a day or so. If you're using Battery Monitor Widget (which is not accurate for gnex), things should eventually settle between -2mA and -60mA per sample.
tip 2: Install BetterBatteryStats and look at which wakelocks dominate. Google search for names of the wakelocks to see how you can fix them.
tip 3: http://checkthis.com/d87t
If nothing seems to help, you can try the "notrim" version, but stick to speeds between 350 and 1350 (don't use OC slots). The notrim version has SR1.5 disabled which could help for those of you with drain issues on my other kernels.
What is tempcontrol and how do I use it?
First, read these two posts: 1 and 2.
Although tempcontrol was designed to be used with the experimental notrim builds because the cpu gets hotter in notrim frequencies, you can actually use tempcontrol to throttle lower frequencies. I haven't tried myself, but theoretically you can set your top speed at say 1.2Ghz and use tempcontrol to throttle at say 60C (instead of the stock value of 63C) resulting in slightly cooler phone. Theoretically.
What is SmartReflex?
SmartReflex performs continuous dynamic voltage scaling around the nominal operating point voltage according to silicon characteristics and operating conditions.
My stable and experimental builds will have SR Class 1.5 enabled by default.
You can disable SR via sysfs
How do I use Variable GPU OC?
You can use Lean Tweaks by Jake, or use the built-in "oc" script. Both leantweaks and my oc script will create an init.d script so the setting sticks at boot. My "checkt" script will also show the current GPU max speed. Note that 512MHz will probably not work for everyone.
307Mhz (stock) is set default by the kernel.
Open Terminal, and type for stock speed of 307Mhz: oc gpu 0
for 384MHz: oc gpu 1
for 512Mhz: oc gpu 2
What are the available sysfs options?
Check this post (thx byrong)
Which governor should I use on JB?
As usual I'd recommend trying all the governors and see which one works best for you. Stock JB, however, is optimized for interactive. The OS will automatically modify various interactive governor parameters on the fly while you're using the phone as part of "project butter". Namely, the following parameters are constantly adjusted by the OS: boostpulse, timer_rate, min_sample_time, hispeed_freq, go_hispeed_load, and above_hispeed_delay.
I hope this helps people if there is any other information you might want added just ask and i will do my best to come up with a comprehensive guide.

No i didn't ask him but i did put all due credits in it and it is in every other gnex forum but the sprint one all brought over by other people so if he has a problem with this he can feel free to pm me and i will get it removed i just figured it give us some easier access to his great kernel. In no way am i claiming this to be my work all support should be directed at the original thread op. I was just trying to make access to his kernel a bit easier for all xda users

That's all hunky dory but just doing things without asking the developer is just not right. Regardless if he has an issue or not. Its like you make something you work diligently on and then somebody just posts it somewhere else.
I dunno maybe its just me but its just common courtesy.

Well i have gotten permission to post this from imoseyon and to keep this thread updated on xda sprint forums for him so it looks like we are all set he got back to me alot faster then i thought he would so every thing should be all good guys
and yes jayare313 i am so used to finding every thing i need on xda some times it s a pain having to check 3 or 4 sites to see if any of your mods for your rom are updated
Sorry. 3 issues here:
1) I need to verify permission from the developer and he needs to verify that he is going to support it here. If someone downloads it, flashes it, and somethings wrong.......who is going to give answers and support it? We have an active community who can help, sure, but the developer has to actively support it here. If he were ready to give support here, he would have posted it here already. And even then it would have to go in general unless he started the thread.
2) There is no source provided in the OP. Kernels must be GPL compliant and listed in the OP.
3) If you did not create it, do not post it in the development section.
Alrighty. Everything should be good now. I'll be keeping an eye out.
OP will be updated soon, with source and I've spoken to the developer.
Thank you guys.

[KERNEL][AOSP4.4/5.1/6.0/7.1] dkp - d2att - 2/4/18

Welcome to decimalman's kernel playground!​
As the name suggests, dkp is a hodgepodge of features and tweaks that I wanted to play with. It should get excellent battery life without feeling sluggish. It doesn't come with its own tuner app, so pick your favorite. Personally, I like Trickster MOD and Kernel Adiutor, so I go out of my way to make things work in them. Most other apps should work, too.
Features:
Overclocking up to 2.1 GHz, but you'll need to increase your voltages to get there (if you can get there at all)
Underclocking down to 54 MHz, with stability improvements
Undervolting compatible with most apps
Fast charge without unplugging first
Glorious animations for the notification and softkey LEDs
Well-integrated erandom means you don't need CrossBreeder or Seeder (recent AOSP builds use ISAAC instead)
freelunch and tierservative governors for optimal battery life without sacrificing responsiveness
Automatic mpdecision and auto-hotplug are only enabled when needed
Adjustable minimum voltage for stability on finicky processors
Optimized UKSM to free up some extra memory
Code optimizations for size and speed
Compiler optimizations (-O3, LTO, and more) because faster is better

Other kernels have their own threads or forums. Discuss them there.
Image dumps (settings, battery life, whatever) belong inside [HIDE][/HIDE] (that's HIDE, if you're on the mobile app) tags.
Be silly. We're here to have fun.
Installation:
Reboot to recovery. I recommend that one recovery...you know, the one that flashes zips? I forget what it's called.
Flash dkp. Optionally, rename and flash dkp-vmin-XXX.zip (see below).
Reboot.
Undervolting:
Undervolting on dkp is more complex than other kernels. Some processors get unstable at lower voltages, so (like the stock kernel) dkp keeps the processor voltage above 1150 mV by default. I refer to this limit as the minimum voltage. In order to undervolt, you'll need to lower the minimum voltage: if you use Trickster MOD or Kernel Adiutor, just disable "Override Minimum Voltage", otherwise rename dkp-vmin-XXX.zip to e.g. dkp-vmin-600.zip (which would apply a 600 mV minimum voltage) and flash it. If this causes instability (crashes, audio/video glitches, etc.), try using dkp-vmin-XXX.zip to apply a higher minimum voltage (somewhere between 950 and 1050 mV seems to work well for most people).

Goodies:
dkp doesn't come with its own splash screen. However, the dkp installer (i.e. the install zip) is smarter than you think, and can apply a custom splash screen for you. Here's how:
Create a folder on your internal storage named "dkp"
Copy a PNG image into the directory, and rename it "splash.png". Alternatively, copy an RLE image (i.e. from a flashable custom splash screen zip) and rename it "splash.rle". Ideally, the image should be roughly 1280x720 to begin with, since it won't be resized.
The image will be used as your splash screen whenever you flash dkp. Reflash to apply initially.
mikedavis120 has put together a how-to video that covers tweaking dkp for optimal battery life. If you're new to dkp, take a look! He also put together a zipped collection of apps that will come in handy while tuning dkp. It also includes a flashable zip, "dkp-debug_v1.zip". After flashing it, running
Code:
su
dkp
from a terminal emulator will collect lots of useful debug information that will make it much easier for me to track down the issue you're having. :good: mikedavis120 recommends installing SuperSU (included in the zip) instead of what's included in you ROM.
sysfs:
It's possible to adjust all the settings available in dkp without using apps. Because they show up as files, settings can be adjusted with file managers, terminal emulators, adb and initscripts. Here's the most interesting files inside sysfs:
/sys/devices/platform/mipi_samsung_oled.513/lcd/panel/panel_colors (not available on newer AOSP builds): display tint (0 = very red, 2 = default, 4 = trinity colors)
/sys/class/misc/gammacontrol (only available on newer AOSP builds): various color controls. See this post for details on enabling Trinity colors on builds that use these controls.
/sys/devices/system/cpu/cpu<N>/cpufreq/UV_mV_table: voltage table
/sys/devices/system/cpu/cpu<N>/cpufreq/scaling_...: scaling_governor is the governor, scaling_min_freq and scaling_max_freq are the minimum and maximum frequencies, scaling_available_governors and scaling_available_frequencies show the available governors and frequencies
/sys/kernel/dkp/force_fast_charge: fast charge
/sys/kernel/dkp/link_core_settings: when linked (the default), frequency settings and some governors are automatically copied to the other core
/sys/kernel/dkp/vmin: minimum processor voltage in mV
/sys/kernel/mm/uksm/run: activate UKSM
auto-hotplug tuners:
These show up in the governor settings for any governor that doesn't do its own hotplugging. They only take effect when using auto-hotplug, so you'll probably need to disable mpdecision in Trickster.
hotplug_intpulse: when set to 1, automatically turns core 2 on whenever the screen/buttons/whatever is pressed. Default is 0.
hotplug_sampling_periods: number of samples to use for average number of running tasks. Default is 15.
hotplug_sampling_rate: number of 'jiffies' (currently 1 jiffy = 10 ms) between each sample of running tasks. Default is 20 (0.2 sec).
hotplug_enable_one_threshold: the average number of running tasks required to turn core 2 on, multiplied by 100. Default is 125 (1.25 tasks on average).
hotplug_disable_one_threshold: the average number of running tasks required to keep core 2 on, multiplied by 100. Default is 250 (2.5 tasks on average).
freelunch/nanolunch tuners:
freelunch and nanolunch aren't materially based on other governors, so their configuration is quite different than other governors. There's lots of tuners, since I haven't really decided on an ideal tuning. I encourage experimentation! I'll explain a bit of how these governors work before actually listing the tuners.
Generally speaking, there are two modes: in "normal" mode, sampling is done occasionally and frequency is generally increased slowly; in "interactive" mode, sampling is done much more quickly, and frequency increases much more quickly. "Interactive" mode ends after several samples of very low usage. The idea of a "hispeed" frequency is used in lots of governors, and it refers to the frequency that the CPU will jump to when more CPU usage is needed; generally, it's a generous estimate of how much CPU will be needed. Here, the hispeed frequency is adjusted on-the-fly, increasing when more CPU is needed and gradually decreasing when the CPU is idle. In "interactive" mode, the hispeed frequency is kept fairly high so that everything will feel snappy.
Hotplugging is taken care of in the least complicated (and in my opinion, most reasonable) way possible: if core 1 is using lots of CPU, and there are several tasks running (in other words, if it's likely that core 2 will have something to do), core 2 is turned on; if either core isn't doing much except using power, core 2 is turned off.
sampling_rate: the usual
hotplug_up_cycles: number of consecutive heavily-loaded samples before core 2 is turned on
hotplug_down_cycles: number of consecutive lightly-loaded samples before core 2 is turned off
hotplug_up_load: number of running tasks required to bring core 2 online
hotplug_up_usage: number of used CPU cycles (in thousands per second) required to bring core 2 online
hotplug_down_usage: number of used CPU cycles (in thousands per second) required on both cores to keep core 2 online
overestimate_khz: number of CPU cycles to overshoot usage by in "normal" mode
hispeed_thresh: if CPU usage is within this many cycles (in thousands per second) of the maximum frequency, frequency will be increased to the hispeed frequency. Generally, hispeed is pretty low in "normal" mode, and fairly high in "interactive" mode.
hispeed_decrease: when the CPU is sitting idle, the hispeed frequency is decreased by this amount each sample (this isn't ideal, but it works)
interaction_hispeed: the initial hispeed frequency when switching to "interactive" mode
interaction_return_cycles: number of consecutive lightly-loaded samples before returning to "normal" mode
interaction_return_usage: number of used CPU cycles (in thousands per second) required to stay in "interactive" mode
interaction_panic (nanolunch only): when set to 1, allows aggressively jumping past the current hispeed frequency under some circumstances
interaction_sampling_rate/overestimate_khz: equivalent to the "normal" versions of the tuners, these take effect in "interactive" mode

Is it possible they are left over from a previous kernel? Because I can def tell the difference usually and seems like it does.
Either way, advise when its updated. This governor seems solid so far.

dkp is based off clean CM source, so it shouldn't have been merged already.
I've got test builds compiling now, and the 3.4 builds will be up shortly. Flashing the trinity-colors test build and this zip will enable trinity colors. You can toggle it with
Code:
su
echo X >/sys/class/mdnie/mdnie/trinity_colors
where X is 0 to disable or 1 to enable.
Edit: and sorry for taking so long to respond.
Edit 2: 3.4 builds are up. http://d-h.st/7Ae
Thnx for this kernel

Maybe I was just seeing things, had just watched jurassic park in 3d.
New "test" build flashed as well as the file to enable it. Thanks for the addition. It's very hard to go back to normal once you've been smurfed depending on your display.
Only issue i'm having ATM is the ability to change the voltage table. My phone doesn't handle undervolting as well and i run a minimum of 950 baseline, if not 975. One of my normal apps wasn't able to set the voltage at all. I'm trying to use performance control which I don't like. It crashes trying to set the voltage on boot but at least I can go in and manually set the values on boot and they stick.
One last question, since this is your kernel, what scheduler do you recommend pairs well to freelunch? What would you use for performance and what would you use for batt?

Answered my own problem. I installed trickster as mentioned in OP and all voltage settings stick no problem with no issues.

Personally, I don't like trinity colors, but I definitely understand the appeal. I merged this into 3.0 and 3.4, so it'll be standard from here on. I'll add a link to the enabler zip in the OP as well.
What app would you normally use? I'll try to support it, since I already provide several voltage interfaces. I didn't realize performance control was crashing (I'm not a fan either, so I only lightly tested). I recently installed Trickster and liked it, so I've been going out of my way to support it. It's also really easy to write support for, so that's a bonus for me.
As for schedulers, I'm not fussy. I've never exhaustively tested performance and battery life, so I don't have a preference and usually run noop or deadline. However, I've had nothing but bad results with ROW (phone never deep sleeps, and I haven't looked into why).

good to know. Trickster mod works fine and you mention it in the OP and it's at no cost in the play store. I wouldn't worry.
I was using an app called kernel tuner because some others would only set 1 core to the governor and not both. I checked that trickster does indeed set both cores to freelunch so once that figured out I removed kernel tuner. Kernel Tuner also has the options for profiles which can be toggled in tasker for varies states. freelunch so far hasn't needed any changing so not worried about it at this point. just as an example, some governors would be better for screen on/off and tasker could switch these to edge out battery life.
The voltage app i was using is simply called voltage control. Kernel tuner doesn't do a nice job of voltage changes. But since trickster does both governor and voltage adjustments well. i'm using that with no problems now.
Thanks for the morfic, having a way to toggle it works well for people. it's as simple as a script so there's that.

I meant to test Voltage Control but Google wasn't letting me download anything. It's a common app, so I'll try to get it working regardless. Kernel Tuner doesn't currently work well with freelunch, and tends to hang when it's trying to read settings in the CPU screen. Otherwise, it's a nice app. I didn't realize it had Tasker support (I use Llama).
I've added a few extra bits to the cpufreq core, so governors that need to be set on both cores (like freelunch) will automatically apply to both cores regardless of what app is used. cpufreq will even enable and disable mpdecision depending on whether a hotplugging governor is running (though Trickster won't show that it's disabled).
I owe ktoonsez for the toggleable trinity colors. I slightly rewrote his patch, but it's still largely his code. It's my policy that anything that not all users will want should be optional and easily configurable.
Edit: I think I've got Voltage Control fixed. I should be able to get Kernel Tuner working without too much work. I haven't even looked into Performance Control yet.

well good job so far. batt life has been top notch. minimal drain in use and my over night idle drain was only a few %. I have things setup to disable wifi when sleep and also turn off mobile data when wifi is connected. A bit over the top but every bit helps.
:good::highfive:
I know I've been grilling you today but...
Kind of curious what the new tunables do. I haven't touched anything since it's working so well but there is always that part of me that wonders what adjust parameters will do. Is there any kind of reference for this governor that could indicate that type of info?
Does your kernel support faux sound app?

[Q] Low bloat roms with decent performance tweaks?

First new thread I've posted in a long time. Hope I'm doing this right.
I just got a galaxy S3 the other day. I have rooted and installed cyanogen
and Mrom.
Neither of these contain the settings that I am used to.
On my last phone (htc evo 4g) I had a rom that included advanced settings,
which allowed for a number of performance tweaks including multiple
processor governor choices, JIT compiler options and the like.
--------------------------------------------------------------------------------------------------
Is there a rom for the S3 that is considered "the best" in terms of low bloat,
speed, and advanced performance settings?
--------------------------------------------------------------------------------------------------
From the description I thought Mrom would be a good choice,
and I have to admit that It's fast, but I miss my processor settings.

There are apps on Play such as tweakmod that allow changing processor settings. The kernel that came with any ROM you flash will only allow specific governors that the developer has tested over and over. Flashing a custom kernel such as BMS, will give you more governors to pick from. CM stock kernel has been good enough for me. I get too many weirdly spaced out random reboots after messing with custom kernels & governors these days, so I just use CM stock, interactive governor. MOAR ROM is not CM based. JIT and ART runtime settings are for KitKat ROMS. ART is still in developmental stages, and can cause issues, as not all apps are compatible.
sent from my GS3
Thanks for the quick reply. I realized last night that I hadn't enabled developer mode on CM
so I found some of the features I was looking for.
I'm going to go back to Mrom http://forum.xda-developers.com/showthread.php?t=2172264
for now because from the descriptions of the LINARO toolchain it seems like it's one of the fastest.
Any other Roms that are considered the "fastest" that I should try. I was thinking maybe liquid smooth.

how to disable CPU cores

I want to know how to disable CPU cores to save power. It was possible on my nexus 5. but on my nexus 6p and now on my htc 10, I'm not sure if it's possible. I read that it's would need a kernel rewrite or something along those lines.
So does anyone know how to do this? I'm running latest LeeDroid ROM if that helps. thanks :good:
That's what I also wanted to know about the 10.
I had the mind before and there I could run with only one core, if not needed the other three cores. But if I needed power, the 4 cores are running.
It would be great, if there is an option in kernel settings to run all the cores only if they are really needed.
So the 10 is only a battery eater... Especially with sense roms I don't come through the day without charging.
On CM 14 or AOSP the battery is much more better, but with better core management it would be famous.
anyone got any info on this?
less cores doesn't mean better battery life, look at u11, "octa-core" and getting better battery life than 10 and anything else. it's een like if you have less cores, the cores which are online have to do all the work and might end up with locked max freq which will result in heat and more drain. so just keep the core control like it is and maybe just underclock

It is possible to disable cores with the custom kernel, and I believe force them to remain off at boot, but the HTC 10 uses a big/little cluster CPU setup and disabling cores isn't how you want to conserve power in my humble opinion.
The HTC 10 and some other modern devices uses BIG.little core ARM processor technology.
So the hardware and software is optimized to use all the cores to chase the best battery life and performance. I'm guessing that unless it's very specific usage scenarios, if you manage to force disable the cores with a custom kernel, you'll see both performance and battery life drop.
I would highly recommend installing a custom kernel, and tweaking the kernel settings while letting the hardware make full use of the BIG.little cluster system for efficiency. For high performance, I'd recommend one of the sense based kernel's that uses the HTC PnP Manager system. Something like Flar's ElementalX or TBalden's cleanslate kernel.
For battery efficiency, since you're really wanting to customize things for the best efficiency and battery life, try out the Helix kernel, by zeroinfinity. It's using a technology to optimize control of the processor based on "EAS" technology. EAS stands for "Energy Aware Scheduling" and zeroinfinity has written his "Helix Engine" to control the power profiles and thus power consumption of different apps, and you can customize the profiles to put any other apps you have in the profiles you want them.
This was a very basic and non technical summary, you can find tons of info on the kernels in the OP of each kernel thread. I would recommend making a backup with TWRP and trying both ElementalX and Helix kernels and seeing what works best in your usage scenario, before you start trying to force disable cores.
Here's a quick article I found on google, I'm at work and only briefly skimmed it, so no promises it's any good, but you can google BIG.little procs on Android mobile devices to find more imformation. https://community.arm.com/processors/b/blog/posts/ten-things-to-know-about-big-little

was a good read, thanks! based on the quote from below from that website sounds like the little cores can drive the most battery savings the most .... which is my goal.
The LITTLE cores can be implemented to target lower leakage and a more moderate performance point, independently from the physical implementation of the big cores that are often tuned for higher frequency.

Stock based sense roms. I just use it with regular rooted builds of leedroid or viper. It works with magisk and has been built to be fully compatible, however I use it for my normal modded system rooted sense based rom with supersu. I don't use or set up magisk, I'm still kind of old school.
But if you were to use magisk, @ZeroInfinity is running magisk as his daily since the last several builds, and I don't believe it's got any bugs or anything that doesn't work in the magisk build. One of the other team members @p50kombi knows a lot about magisk if you need to know anything further, I just have very limited magisk knowledge I'm general.

Great I also use supersu not magisk, probably same old school thing...also too tough getting things to play nice with magisk IMO. So for supersu do i just install v012 r1 systemless kernel and it should just work w/ leedoird? did you notice any functions on lee droid not working?
also do you underclock? recommend any kernel managers?

It's version 17, you'll download it from this post https://forum.xda-developers.com/showpost.php?p=73068312&postcount=1216 , sorry that link you had shouldn't be there, but systemless is the magisk version but now there's only one version, and the Aroma installer will let you choose the normal non-magisk version.
In the installer, there's a question that asks about installing custom scripts, I use the @ZeroInfinity script, the one from @roger81 and @TotallyAnxious are good too so you can't really go wrong, but I recommend starting with zero's, and you can reflash to experiment once you get going good with it. Rogers is great for battery life but his is a little more custom and extreme, which is why I'd start.
I use EXKM kernel manager, but I really recommend not changing many settings at first. Definitely leave the governor default with this kernel. I would run it like it comes out of the box, and see how your apps and battery life goes, and if you have apps causing a lot of drainage, maybe add them to the helix engine profiles before you start changing clock speeds.
You'll notice with EXKM the core frequencies reported in real time will look different from how it looks with a stock based kernel, but don't let that scare you.
My only other recommendation is if you use any other power saving apps like greenify or doze (I don't use any of them personally but some do) I would first get used to the kernel without them, so you kind of have a better idea of baseline.

It is you're correct, but there's a lot of "super doze" and dozingest doze around" sort of mods and tweaks people use, it's the extra modified stuff I would avoid for now, until baseline is established. However once you get things ironed out, @RogerF81 (if I spelled that Right) has tons of good info on further tweaking. He once tweaked his battery life to something like 7 or 8 hours screen on time with the Helix EAS kernel. That's just showing off.
Glad you like the Aroma installer, it nearly killed the poor dev trying to get it set up when he first started implementing it, he still probably throws keyboards if I ask for a black theme lol.

Thermals and Kernel Managers

Thermals, Kernel Managers and their affect on short and long term battery life.
As requested, by fellow LePro 3 owners, I created this thread for a discussion on the benefits of thermal management, using manual thermal settings, and sharing flashable thermals and user settings. To be clear I am not yet an expert on this subject, so I am learning along with everyone else. But, why not share the experience?
Of course we want our phones to last, while also pushing them to their limits, but in a safe and efficient manner. Recently our developers have shared their ideas on thermal management, and they have been gracious enough to allow us access to their own settings, that can be used across multiple builds. See the link below to download the first set of flashable thermal management options.
Recently, some of us have encountered shutdown issues, with some roms having battery stats reporting issues, unexpected shutdowns, and unrelated unrelated lockscreen issues. We users have found that often these troubled builds can be fixed by flashing a fix. Such as the thermals from a previous or other builds that did not have the same issue. Fortunately, it appears that we can use alternate perf and thermal management files that have not only offered a quick fix for some of these current issues, but also offers a longterm solution for using old, new, and future roms builds...collectively. :good:
The plan is to make this discussion much more extensive and simple
So consider this initial post to be an ever changing rough draft.
The end goal is to make it much easier for people to access and share their thermal management files or settings in one easily found central location, and hopefully for everyone to share their suggestions along the way
Helpful to Gamers who want safe power and speed.
Helpful to Non-Gamer's who want simply want stable performance, long battery life
Help everyone by helping us learn to optimize our phones to last for the longterm.
For me, no more repeating the same stuff over and over on various Rom threads, or private messages. No more having trouble digging through threads to find a recommended thermal or setting. So please participate, we can keep the OP updated whenever anything new comes along. Should I get access to something new I will add it to the Megadrive and make a post
Inventory
So far we have the thermals from Lineage, AEX, Balkan, AICP, EUI and in my view one the best is the latest by Jabashque. The idea of this post is to share the thermal settings so that they can be used on whichever ROM you want to try out.
Finally, you do not necessarily need to use these thermals unless you have an issue with general usage, heat or battery life. However, you will immediately notice the benefits.
Edit ( Updated Info)
Regarding kernels: Personally, I use BlackScreen 6.3, it has a long list of governors and I like options.
Currently the best thermal option is the Jabashque edit ( Thermal Fix 7 ) Get it Here: https://forum.xda-developers.com/showpost.php?p=78717015&postcount=18
These thermals work!
Over the past 2 weeks, I have gone back and tried several old ROMs, and these thermal and profiles make those old Roms perform so much better! For example, the September 3rd JMXL version of DotOS.: Yes, Its outstanding with the Sergey thermal. BootLegger's is also much improved, and it was already pretty great as it was. The Miui ROMs, are significantly improved by far! etc.
Of course we have so many great Roms. Occasionally, we get a build that is experimental and it may have unexpected issues. We have seen over the past week that flashing an alternate thermal is a perfect way to save the installation without having to revert to an earlier build. I mentioned old Roms above, they also work on every single Pie Rom.
Here is My Mega Drive Link for all of Thermals that I have collected so far
https://mega.nz/#F!9EokAQTb!Au6cBnJaCJXZrUlaXSLjhg
Alternate Link with key
Link: https://mega.nz/#F!9EokAQTb
Key: Au6cBnJaCJXZrUlaXSLjhg
Jabasque's thermals are in the Jabashque folder. Version 1 and 2 :
Probably shouldn't result in any difference if not gaming.
"Most likely, it would only be noticeable if you're not throttled down to 1440/1900MHz and you're running something that's using 100% cpu" ( Jabashque)
What to use
If you are wanting long battery life and low temperatures use Sergey's thermal or JaBashque version 1
If you want stock EUI faster throttling but slightly higher temps use the ShivateJappedi EUI thermal.
If you want to leave your cores unchanged from the default setting with higher temp throttling, more full power access and yet still safe while use JaBashque 6 Its a rework of the EUI 30s thermals designed to work better on modern Pie Roms : See more information here: https://review.lineageos.org/c/LineageOS/android_device_leeco_zl1/+/238809
Soon, I will create a post in the reserved section below to deeply define the details and differences between these thermals. Because while they all have similarities, they are also very different from one another.
In addition, I plan to add various kernel manager settings for various uses : Gaming, Long Life etc.
Finally, even when moving to another Rom. kernel manager programs such as Ex Kernel Manager will allow you to import and use saved profiles. It seems that it is possible to save the best of each of these thermals by saving the profiles of each. We can share those settings! Then later you can manually choose within your kernel manager which settings you want to use by simply importing choosing a preferred profile.
I hope this clears up the confusion. As mentioned this is a work in progress that was requested by 3 people. This is just the beginning of this discussion that will help everyone understand how to use Kernel Managers and the add-on thermals patches. I need to do some further research to make it all worthwhile . For example, although I love the elementalX governor, I haven't researched it enough to explain why I think it's better. So I plan to find out specifically what it's actually doing vs what other governors do, and how does changing sample rates, and wake locks affect performance and battery life etc.
If there are any experts out there? Please chime in and contribute.
See Updated information from Jabashque, which explains the differences between patch 1 and patch 2

Installation
Dirty flash the patch that you want to use..thats it.
If you want to try a different patch, dirty flash the Rom, reflash Magisk and dirty flash the patch
You can manually adjust settings by going to /vendor/etc/thermal-engine.conf
Update from JaBashque Edit April 21 2019: ( I use ThermalFix7, its my personal favorite/ it is the best and the safest period.)
@tsongming
Hey, after seeing your thread about thermals, I felt I should write an explanation about how my v1 and v2 differ from stock EUI thermals that you could add to that forum post, since the one you have on there was me describing the difference between v1 and v2, not stock EUI: "JaBashque"
There are two different set of sensors that the original config monitors for the CPU:
the CPU temp sensors (tsens_tz_sensor{4,6,9,11}) and xo_therm_buf. The CPU temp sensors measure the temps of the cores themselves. xo_therm_buf measures what seems to be some sort of overall temperature, though I'm not sure what in particular. However, xo_therm_buf does correlate more directly with how hot your phone feels.
Original:
thermal-engine rapidly throttles your CPU down to 902MHz on the little cores and 825MHz on the big cores when any one of the cores hits 95C, and stops only when the hottest core drops back to 65C. When xo_therm_buf gets to 43C, thermal-engine slowly throttles all your cores to 902MHZ little and 825MHz big until xo_therm_buf drops back to 40C.
Patchset 1:
thermal-engine rapidly throttles your CPU down to 902MHz on the little cores and 825MHz on the big cores when any one of the cores hits 85C, and stops only when the hottest core drops back to 65C. When xo_therm_buf gets to 37C, thermal-engine throttles all your cores to 1440MHZ little and 1900MHz big until xo_therm_buf drops back to 34C. When xo_therm_buf gets to 43C, thermal-engine throttles all your cores to 1132MHZ little and 1363MHz big until xo_therm_buf drops back to 40C. When xo_therm_buf gets to 50C, thermal-engine throttles all your cores to 979MHZ little and 1132MHz big until xo_therm_buf drops back to 43C.
Patchset 2:
thermal-engine throttles your CPU down to 1516MHz on the little cores and 2054MHz on the big cores when any one of the cores hits 95C, and stops only when the hottest core drops back to 65C.
This change was made because I realized that the previous version still had a situation where the CPU performance can tank unpredictably. xo_therm_buf-related CPU throttling is same as Patchset 1.
Thanks to JaBashque for sharing his work! Patch-set 2 is my personal preference. Although the Sergey Perf + Combo is also very good.
@tsongming
Thank you very much for listen us and always give your help.
Rigth now I am on BaikalOS 28th December 2018, if I want to flash any Profile of those, what I should to do (Clean flash? This first, later that etc... and Wich of them I should ti flash for best battery, I do not play on movil)
I am very curious for test this...
I have x722, I do not play. I am now on aex 5.7 oreo. The most depends on the battery, so which zip to flash ? This is a great topic.

You can dirty flash these thermals.
Personally I like Sergey and Jabashque version 2 the best so far on Pie roms.
The Shivate patch works really well on Marshmallow, Nougat and Oreo.
The Sergey patch works really well on Oreo and Pie, I haven't tried it on Nougat Roms yet.
You can manually adjust settings by going to /vendor/etc/thermal-engine.conf and In this same folder ( vendor/etc) you can also make audio changes, and I am not talking about policies and Tasha.xml files, although you would make changes to those files too, if wanted. This will be something that we can discuss in more detail soon.

Either the Sergey or the JaBashque 2 with be perfect, depending on what you want.
Use Sergey if your goal is battery saving.
Use JaBashque 2 if you want better gaming performance.
@tsongming thank you for this useful thread. I just have one question. I noticed that sergey's thermal file you uploaded comes also with perf so do you know is it maybe EUI perf and if not is it possible to upload just sergey's thermal without perf? Thanks.
I'm using aex 6.2 and i play a lot of games, but i looking for something that gives the power to run the games and after that (of course after some time without using the cellphone to cooldown) use the phone without worry of him overheat with simple use like 39 or 37 ºC. Do you have something like that?
I have a x722

Sure, I can extract the perf, I will do that and add it to a separate folder so that there are two options.
Edit: Here is the Sergey thermal only
I removed the perf and added the additional key edit options from the Jabashque patch. So this a combo patch.
Use at your own risk
However, I have tested this and it works fine. I wanted to give the caveat that I am a Noob at this! But its okay. FYI: all I did was remove the perf, so now the perf will come from the rom and I added the Moshe key feature, which some Roms such as AICP includes anyway.

Use the Jabashque 2
See updated in depth info from JaBashque : here: https://forum.xda-developers.com/showpost.php?p=78670166&postcount=2
So, thank you for your work!!One question,i am at the last AICP Pie,do you believe is better to flash one of these or stay with the settings of AICP?
Thanks in advance!
Don't work
I used to play pubg and the big stay on 1,4 ghz and little on 1,0 ghz

If you are not having any issues, then don't install any of these.
However, if you want to try it, keep a record of your existing performance, battery life, heat levels for battery and CPU (when idle) and compare that against using these thermals.
If you flash one of these thermals and don't like it. You can quickly return to your previous settings by dirty flashing your rom, or by restoring the system part of a nandroid backup.

So which one of the 5 thermals did you try? Some of them include perf
Understand that you still have to setup your kernel manager. If you are wanting to use it for Gaming use the JaBashque version 2 to and leave the cores on the highest setting.
Yes, it works. It works for me a and a lot of other people on Telegram
If you want low temperatures and long battery life underclock the cores at idle my battery hovers around 85 F and the CPU are around 100-105F
Just so you know you can access your thermal.conf file and edit it manually to increase your thermal limit in /vendor/etc/thermal-engine.conf
Next, save a copy of your existing current setup as a profile, so you can easy switch from one to another with ease and easily compare it to the changes of using an alternative file. You can tweak it to the settings that you are wanting...Just keep safety in mind or you could burn up your CPU.
UpDate!
@jabashque has spent time recently improving his thermals further, and released several new versions .
The latest and greatest is now version 6!
Get it here: https://mega.nz/#!pFoSRaQA!R068WV-YltbQAFzuc3aH72z_OPyrN2uBjgsux2h0dNY
If you like it, please thank him!
Anyone who is using the last build of Jabashque 6 . It has a small error with he tthermal.
Flash this zip file from my Mega drive.

I want to install Bootleggers os 8.1 on x722 and I have a question: after installing romu and gapps and initial configuration I can flash BS5.1-r3 AND thermal.zip a magisk mantle? will thermal.zip not interfere with BS? Thank you.

Sorry I haven't been on XDA much recently, and never received the notification.
If you use Bootleggers, the stock kernel is fine. But blackScreen 6.3 will work fine and it gives you more options. You flash the thermal at anytime. I recommend the Thermal-fix7 which is Jabashque 6 that I edited to fix a typo. No there is no conflict
