changelog:
24/06/2017
- removed i/o scheduler switcher. The random reboot should be gone ( my j5 didnt have any reboot with i/o sched swither and neither without it, while being in idle though, as i'm not using it)
- fixed two permissions of powersuspend (0666 --> 0644)
- added @squid2's lionfish governor. It is supposed to be more battery friendly. Test and report your feedback.
- added sociopath tcp: "this is basically tcp reno with no slow start and a much more aggressive ssthresh recalculation (lowers it by 5% instead of 50%)"
- fixed 9 vulnerabilities
about doubletap2wake and sweep2sleep:
this new update was supposed to have dt2w and sweep2sleep. I've added them by using the commits from other kernel and they were working, both. However, there were some issues:
1) dt2w wasn't working on the full screen. Even after choosing "full" in kerneladiutor, i still had to double tap in the bottom of the screen (half) to wake it. When i was double tapping on the other half of the screen (top), it wasn't working.
2) i dont know if sweep2sleep is supposed to work only in the bottom of the screen, but that's how it was working. It was fine though.
3) phone wasn't going to deep sleep, even when both were off. This is the major issue and that's why i've removed dt2w and sweep2sleep. I don't really have the knowledge to fix that and i'm not willing to spend time for that. Those commits which i've picked has powersuspend hooks and i had to update powersuspend to v1.8.1 as that kernel. Perhaps this version of powersuspend wasn't working properly and that's why it was causing the phone to not go into deep sleep? I don't know...

09/05/2017
- added i/o switcher: A driver which change the i/o scheduler to noop automatically when screen goes off and restore the i/o scheduler which was set before when screen is on after 10 seconds
- silenced much more kernel logs
- re-enabled swap & zram
- added sys interface to configure linux printk logging (debugging purpose)
- added gpu time_in_state stats (similar to cpu stats)
- added quick wakeup driver: Allow kernel driver to do periodic jobs without resuming the full system. It should increase battery life.
- added toggles for gentle_fair_sleepers and arch_power
- tcp cubic fixes
- added sioplus, zen v2 and bfq schedulers
- enabled conservative governor
- fixed some memory leaks
- fixed a problem where reboot on android panics the kernel almost every time when file systems are mounted over loop devices
- updated power efficient workqueue + fixes; enabled by default
- added gpu governor whitelist to prevent you from enabling gpu governors which are unstable / incomplete (bw_hwmon, bw_vbif, gpubw_mon; all those 3 make the phone freeze once are enabled). Now when you try to enable those, it wont change anything.
- misc fixes and improvements

07/05/2017
- wifi module is now smaller as it should be (~40mb -> ~3mb)
- disabled some kernel logs
- disabled zram, swap and everything else related to swap
- allow 320k aac encoding
- misc fixes and improvements
- increased charge time from 30s to 100s when battery status is near full
(when charger is online for a long time, such as 12 hour, the battery status changes from charging to full and resumes charging.
The reason is that battery is not full at the first full state. So increse charge time from 30s to 100s when battery status is
near to full. This methods will reduce the number of recharging time)

02/05/2017
- disabled android log and crc check by default
- added back kcal (color control), drivedroid support and power efficient workqueues
- removed verifiedbootstate flag from /proc/cmdline (in order to pass the safetynet cts check with an unlocked bootloader, this patch is needed); i dont know if pokemon go game or something similar works now, you can check and report as im not playing those games)
- tweaks to improve i/o latency on ssd
- fixed few security vulnerabilities (such as dirtycow and quadrooter)
- many patches has been applied for faster i/o read / write
- governors are more friendly towards latency-sensitive bursty workloads
- and other misc tweaks
Click to expand...
Click to collapse
16/03/2017
- reworked from scratch and based on caf source for more performance / smoothness (now i can clearly see a difference )
- updated gpu driver to mm source
- added crc toggle (enable / disable)
- enabled adaptive lmk by default and set vmpressure_file_min for msm8916 from caf
- disabled arch_power
- frezee bug is gone
- removed: Ota, kcal, soundcontrol, power efficient workqueues, zen governor, frandom
- removed also the ramdisk modifications as it may lower performance / smoothness. I might try again in future.

small update
Few screenshots were attached at the end of first post.
There has been a small issue in the script of Anykernel, so OTA wont work. I have fixed this and updated the download links.
Please download and reinstall again in order to get OTA working. Im sorry for this small issue.

Installing kernel now, will get back with results in a couple of days.

This kernel is made for J500FN (using J500FN sources) but because it's using AnyKernel2, it should work on all models.
I've wrote this at notes in first post:
2. This kernel uses AnyKernel 2, just like the Linaro Kernel by Nick Verse. So, it should work on all Galaxy J5 (2015) models. You test and report.

Yea xD
Let's stay on topic. Not all people know about animes haha.
To people who are asking what does mean that: "dattebayo" it's a Japanese word which Naruto says it often in the anime, it's like a verbal tic. It means "you know" or "believe it".

Just be patient.
I just started building it. It will be available soon.

Lollipop version is out
Lollipop version is out. You find the download links in first post.
Lollipop version has additional changes:
Code:
-built with AOSP 4.8 toolchain (if im using 4.9 the phone gets stuck at Galaxy J5 logo, not even bootanimation; i didnt take a logcat yet)
-disabled CPU L2 Cache during video sessions to save more power[B][COLOR="Red"]*[/COLOR][/B]
-more security fixes[B][COLOR="Red"]*[/COLOR][/B]
* The changes with asterisk were already present on Marshmallow kernel.
The flashable zip has 24/01/2017 date because Lollipop version was supposed to be released yesterday too. However, if you take a look at Settings > About phone or Kernel Adiutor you will see that the kernel was built today.
Im waiting for reviews. I wanna know if you encounter the same problem like me, mentioned at notes in first post at 2) .
Now i can resume to RR, to work on a final update. RR kernel will also have Tensei features and probably few other changes for improving the battery since CM is faster than Touchwiz.

Phone "feels" faster, but that could also just be a placebo.
The only bug I've found yet is that my camera froze once after double-tapping to open it, but that hasn't happened since.

Important / read before flash mandatory
This is the first stable SimplKernel build which is 5.1.1 based and unified. It only supports 5.1.1 and the listed variants. No other variants.
For W8: Seems that you can run 5.1.1, but no new bootloader. If you run 5.1.1 and this and have fingerprint on your Rom, the second boot won't work anymore and you'll need Odin. A Rom with removed Fingerprint may solve it, but I don't have a W8 and can't test or say for sure. Best is to wait for the new bootloader alltogether.
For all other variants: This should work on L/S/K, if/when they receive 5.1.1, but someone will need to confirm by flashing.
Same counts for I.
If you run 5.1.1 without the new bootloader, you will encounter the same issue described above for the W8. Same counts: Better wait for the new Bootloader.
Introduction
SimplKernel is developed by SimplTeam. We originate from the Note4 and have a long story of success there. Our builds are known for being close to stock, yet full of useful features and enhancements. The aim is to provide maximum performance and maximum batterylife. No compromises.

- The 5.1.1 Bootloader. No support for problems you encounter without the new Bootloader.
Via recovery
You have to have a custom recovery like TWRP, Philz or CWM installed.
- Download the kernel
- Reboot to recovery
- A backup is always recommended
- Flash the zip file
- You're done! Reboot and enjoy.
Via Flashify
- Make sure that you are rooted.
- Download the zip and extract the boot.img
- Download the free app Flashify (Caution: Free Version only allows 3 flashes per day!)
- Grant Flashify Root permissions.
- In main screen, select Boot image and navigate to the previously extracted boot.img

If you apply Interactive or simplgov in Synapse, ALWAYS enable it for both clusters. Enabling it for only one will cause funny effects, perhaps even a solid chaos, batterydrain and other unpleasant things. You've been warned.

Nice! will test it on my w8! im on XtreStoLite 2.0 Odex without Fingerprint since my bootloader is still 5.0.2
Edit : confirmed second boot working without fingerprint on the rom!

working great on my 925F edge, with 5.1.1 bootloader and XtreStrolite rom <3

I looked at your github. What are the memory killer tweaks? I don't see anything that really seems to correlate to memory killer. Also, how did you disable OOM killer? From what I've seen, OOM is present but does nothing. I'm just asking for my own sanity

Oh, my changelog for this build is as confused as my current state of mind is. OOM is back and enabled in this build, it was disabled prior to building in the configuration.
And looked at the commit history, yes you do seem to be right about missing memory-killer patches.
Sorry, I haven't managed to get all the patches I used to run in yet. Something was blocking boot for all week, thats why 3 governors are still disabled.
Today was my graduation day, it's a bit turbulent.. Published today instead on next Monday/Tuesday since it only lacks some minor patches at the moment

OK, just making sure I'm not going crazy. I've spent months trying to figure Samsung's method of memory management out, my head has nearly exploded more times than I can count. I wouldn't waste your time with OOM or LMK stuff in the kernel. It does nothing. All of the memory management stuff is in the services.jar, and they're changing it in the next update. So the little bit I have figured out will be useless lol. Congrats on graduating too BTW

Does this kernel root also? I use one of the kernels that rooted 5.1.1 automatically and want to know if I will lose root by flashing this. Thanks in advance for any help.

Thanks Yeah, they work in mysterious ways that much is true. Otherwise disabling it should have solved it. Well, it didn't. At least I found a method to get new sourcecode within 15min after the firmware release.. They kind of rolled out the red carpet for me now.

Theoretically, yes. In reality I updated the ramdisk about 5min prior to uploading and couldn't test if it works. But I believe that it does

Interactive, it's greatly adapted to the clusters and twice as big as the "usual" old Interactive thanks to it. You can also give simplgov a shot, it's basically Interactive with some changes I wanted to try out

Just flashed the kernel lets see how it performs. Currently on the interactive governor. Can you give some insight into your simplgov governor? What does it compare to?

Pls Read This before flashing:
You need ROM's default kernel before flashing this as this kernel makes use of AnyKernel 2 by @osm0sis. Make sure you have it otherwise clean flash the kernel with the rom to avoid any issues.(At least dirty flash rom+kernel) Credits to @attack11 for some part of install script.Read FAQ's and changelogs in 2nd post. THIS KERNEL COMES FINE TUNED OUT OF THE BOX.
How to Flash:
1. Download the kernel and place it into your phone storage
2. Reboot into recovery
3. Install the kernel
4. (optional) Wipe Dalvik/ART Cache and Cache partitions
5. Reboot and enjoy!

Looking for changelogs??
https://github.com/Megatron007/ghost/commits/mega-new Here they are!!!
F.A.Q. - Read this before complaining!
1. My phone exploded, HELP!
A: I don't answer to problems without a log. The log file is in /proc/last_kmsg. Paste it on pastie.org and link it on your post. Logcats are useless for Kernel purposes, don't bother posting them.
2. This kernel works on Y or X rom?
A: Works on all CM12/12.1 and AOSP roms. Not for stock roms!!
3. OMG BATTERY SUCKZ, ITZ DEAD IN 45 MINUTES, HELP!
A: As you can imagine I don't build kernels to decrease battery life. All the battery life problems come from your apps, either Facebook, or Maps, or some Location Service being enabled etc etc. Check your damn wakelocks and fix them, the kernel is not responsible for them.
4. How do I flash this?
A: Read the OP, theres a reason why I added instructions on it.
5. What is a data loss? Did I just had one?
A: Data loss is simply having the connection cut for X periods of time, usually few seconds. Grey bars means the device is not connected to Google services for some weird reason, but you'll still have internet connection.
6. OP is arrogant, I'm gonna call the Internet Police?
A: Deal with it.

@Megatron007 excuseme but i see in kernel adiutor with your RR ROM that the kernel doesn't have any customization that you recommended in you BLISSPOP ROM... that's ok? :/

Your warranty is now void.
We are not responsible if your phone, sdcard or anything else will be damaged, broken, bricked, bootlooping or detonating in a thermonuclear reaction.
YOU are choosing to make these modifications and accept the fact that something might go horribly wrong.
Intro
This kernel was made for my own personal use but seen as I had an updater app for tornado kernel which has been abandoned I have decided to share both the kernel and updater app here. As this kernel is mainly for my own personal use I will not be adding all the bells and whistles. If you prefer performance along with battery over power than this may be for you.
Install:
You need:
- Stock 20A, 20B, 20C or 20D -- Marshmallow
- H815 ONLY
- An unlocked Bootloader
- Custom recovery
Via recovery: latest TWRP here
- Download the kernel
- Reboot to recovery
- Flash the zip file
- You're done! Reboot and enjoy.

Thanks, the app is up now. I thought I had pushed the changes before I reset it, but didn't so had to rewrite some of it. Apologies for the delay.

No problem, glad to see new stuff around. I like the combos (mod + settings app), in this case kernel + app
Thx

Of course. After booting the system informs that the external sd is corrupt and wants to wipe it. After returning to stock, issue disappeared.

Thanks. I haven't any issues and tried a couple of sdcards. I remember this being an issue in tornado kernel and savoca fixed it. Thought I had already included that commit but looks like it disappeared after the M merge. I'll add it back in now and update it if you could let me know if it now works for you?
Edit: Can't load the texfat module as it's signed by LG and it is not open source so can;t build it. Savocas hack is for some reason not working for me . Currently trying to work my way around this. So far no luck...

The time issue seems to be on all M kernels besides STOCK, even building bare stock kernel gives the same issue. It resets back to the proper time a couple seconds after boot but still annoying. I'll have to see if I can spot anything for that. Please try the attached kernel to see if it fixes exfat, thanks.

If this is of any help (higly doubt it but here goes nothing):
H815-EUR GERMANY
Using pre-rooted stock 5.1 KDZ = exFAT support breaks.
Pulling already set up 5.1 system and injecting it with root = exFAT works.
Using SuperSU zip installer on 5.1 = exFAT works.
Using prebuilt, matching, repacked 6.0 boot.img = exFAT support breaks.
Pulling boot.img from stock system state of own device and repacking = exFAT works.
Using Systemless Root = exFAT works.
How likely is it that the kernel is aware that it's not operating on the device it was first flashed/built for? Tbh, I don't know anything about kernel development. It's just, whenever I flashed a kernel that was pulled from another device or modified without ever touching another device, as it might have been the case in those prebuilt repacked kernels, exFAT support broke down.

Does FauxSound Mod increases sound volume?

On my Device the sd card have an error too after installing this kernel. I reinstalled Genisys Rom and now all woks fine. I will test the kernel at a later time again. :good:

NOTES - MUST READ
1. Do not ask or request overclock. It wont be added.
2. This kernel uses AnyKernel 2, just like the Linaro Kernel by Nick Verse. So, it should work on all Galaxy J5 (2015) models. You test and report.
3. ROOT is not included in kernel, neither in the flashable zip. You have to flash SuperSU zip manually, after flashing the kernel.
4. For some reason, Kernel Adiutor still show the frequencies below 800Mhz, but those are not being used as i dont want to.
5. F2FS is not enabled yet.
6. I've just found that QuadRooter Scanner still show a vulnerability. I think I've forgot to apply a commit since on lollipop version it's fixed. I'll look later and it'll be fixed in next release.

REQUIREMENTS / COMPATIBILITY:
- Galaxy J5 2015
- Nougat ROM based on LOS/AOSP. While it should work on all, keep in mind that this has been tested mainly on LOS.
- TWRP 5.1.1
It should work on all models as ive stated at notes.
However, if it doesnt work on your model (other than J500FN) or if you encounter issues, then try to remove the dtb.img from kernel zip and flash it again after restoring the boot.img which the ROM you are using came with.
The dtb included in zip is J500FN one and thats why it may not work or you may have issues. Ive included the dtb because SoUnd001 did some changes to this (like using 50mhz frequency) and i dont want those changes. To overwrite those changes, i had to include the dtb.

FEATURES:
-Based on LA.BR.1.1.3 (the source left by @Nick Verse and @ganesh varma)
-Several CAF patches
-ZRAM enabled

-QuickWakeup driver
-Drivedroid support - put an OS on your phone and boot your PC using the phone. Not tested, but it should work.
-governors: default + enabled ondemand & conservative governors
-schedulers: default + FIOPS, SIO, SIOPLUS, ZEN v2 and BFQ I/O schedulers
-enabled advanced TCP congestions: default ones + Westwood, HSTCP, HYBLA, HTCP, Vegas, Veno, Scalable, LP, Yeah, Illinois
-4 hotplugs: IntelliPlug, MSM Hotplug, Bricked (MP DECISION), Alucard
-tweak for better network speed
-tweaks to improve I/O latency on SSD; many patches has been applied for faster I/O read / write
-CRC toggle: enabled by default (disable it for more 30% performance according to its description)
-android log toggle on/off: disabled by default Seems to be buggy on LOS/AOSP. Ill check it later.
-Fsync toggle on/off: Disabling it should improve the performance, but there might be data loss. More details here: https://forum.xda-developers.com/showpost.php?p=33381928&postcount=5
-arch_power and gentle_fair_sleepers toggles
-disabled CPU L2 Cache during video sessions to save more power
-removed verifiedbootstate flag from /proc/cmdline (in order to pass the SafetyNet CTS check with an unlocked bootloader, this patch is needed); I dont know if Pokemon GO game or something similar works now, you can check and report as im not playing those games)

09/05/2017
- added I/O switcher: a driver which change the I/O scheduler to noop automatically when screen goes off and restore the I/O scheduler which was set before when screen is on after 10 seconds
- silenced much more kernel logs
- re-enabled SWAP & ZRAM
- added sys interface to configure linux printk logging (debugging purpose)
- added GPU time_in_state stats (similar to CPU stats)
- added Quick Wakeup driver: Allow kernel driver to do periodic jobs without resuming the full system. It should increase battery life.
- added toggles for gentle_fair_sleepers and arch_power
- TCP cubic fixes
- added SIOPLUS, ZEN v2 and BFQ schedulers
- enabled conservative governor
- fixed some memory leaks
- fixed a problem where reboot on Android panics the kernel almost every time when file systems are mounted over loop devices
- updated power efficient workqueue + fixes; enabled by default
- added GPU governor whitelist to prevent you from enabling GPU governors which are unstable / incomplete (bw_hwmon, bw_vbif, gpubw_mon; all those 3 make the phone freeze once are enabled). Now when you try to enable those, it wont change anything.
- misc fixes and improvements

07/05/2017
- wifi module is now smaller as it should be (~40mb -> ~3mb)
- disabled some kernel logs
- disabled ZRAM, SWAP and everything else related to swap
- allow 320K AAC encoding
- misc fixes and improvements
- increased charge time from 30s to 100s when battery status is near full
(When charger is online for a long time, such as 12 hour, the battery status changes from charging to full and resumes charging.
The reason is that battery is not full at the first full state. So increse charge time from 30s to 100s when battery status is
near to full. This methods will reduce the number of recharging time)

- tweaks to improve i/o latency on ssd
- fixed few security vulnerabilities (such as dirtycow and quadrooter)
- many patches has been applied for faster i/o read / write
- governors are more friendly towards latency-sensitive bursty workloads
- and other misc tweaks

All the features are mentioned in first post. The governors you've mentioned aren't present, but the zen scheduler is.

Here's a thread with detailed descriptions/information about governors, I/O schedulers (including Zen), hotplugs, TCP congestions. There's also benchmarks and comparisons.

@#Henkate you're becoming a pro in building custom kernels :good:

No. Please read my post here: https://forum.xda-developers.com/showpost.php?p=72280158&postcount=131 . That doesn't mean that it can't have a good SOT. I've got 7-8h in past when I used CM13 and as you know it doesn't have these frequencies neither.
I'm waiting for feedbacks. Take your time for that.
Last but not least, lemme remind you again that this kernel wouldn't be possible without the guys mentioned at credits.
EDIT:
QuadRooter Scanner still show a vulnerability. I think I've forgot to apply a commit since on lollipop version it's fixed. I'll look later and it'll be fixed in next release.

Sadly I am not on 7.1.1 so i can't test this. :crying:
Awesome job! First custom kernel for Nougat :laugh:

This kernel has support VOLTE ?

I guess you meant ramdisk which is a part of boot.img. No, it doesn't.
But if the ROM which you're using would get volte support, then it'll work with this kernel as well since it's using the ramdisk from the actual kernel.
E.g.: Let's say that there is a new update of LOS which has volte support (in ramdisk, but also rom). After flashing the new update, you'll get the kernel which ROM is using. Then you flash my kernel and it'll use same ramdisk with volte support because I'm using AnyKernel (Google it), so i wouldn't have to make the changes from the new update manually.

Kernels don't need to support volte. It's the rom which does it.
You should ask SoUnd1 to add the volte support.

Both kernel & rom must support the volte

Thank you for using it!
I'd like to hear feedbacks though, but take your time for that.
Same goes to the other people which have downloaded and using it. If you want new releases, let me know your feedback from the actual release. I need to know if you have problems and your overall experience.

CPU Overclock would be awesome otherwise it's pretty good in terms of battery,performance and stability

To enable SDCARDFS, I quote @freak07:
1. Open the file system/build.prop and add the line "ro.sys.sdcardfs=true" without the quotes at the bottom and
Make sure your selinux is set to permissive. You can either do this via an app or via script.
here is the download for a script: https://www.androidfilehost.com/?w=files&flid=155912
2. Extract the script and put it in either system/etc/init.d or /system/su.d or /su.d
3. Set the file´s permissions to rwxr-xr-x (755)

I'm hoping. Working with the Pixel isn't anything like it is for the Nexus 6P. I'm still figuring it out.

Oh man, that's great news bud, good luck! Just flashed the kernel. Does this have the sdcardfs commits to be compatible with sdcardfs?
EDIT: nevermind I checked GitHub, didn't see them. Thanks man, testing it now
---------- Post added at 04:08 AM ---------- Previous post was at 04:03 AM ----------
Just a couple feature requests should be easy ones. High brightness mode, backlight dimmer, and to be able to block all the wakelocks ex kernel manager, there's a slew of them, not sure the commits. One last possible would be high-speed congestion control. Sorry, longer than I wanted, but the high-speed is secondary.

It has sdcardfs, but it's completely stock. For the time being, I chose not to commit anything to it. So no current plans to support it. I'm hoping to make this a lean type of kernel, with a few tweaks available. I play Dawn of Titans a lot, and having smooth gameplay is something I look for in a kernel/ROM. Hopefully my kernel (and upcoming ROM) will work perfectly together and create a great platform.

Sounds like a plan. Sdcardfs isn't a dire need, lol. Just wondering. So you're saying if I add the build.prop commit for sdcardfs it won't work right? Also looking forward to what this brings, it's running incredibly smooth since booting.

I'm not sure honestly. I think it'll work, but not very well. People have made LOTS of patches to it to improve it. I might if I get the time, but thats last on my list.

Probably you will face a lot of crashes when accessing storage.

Also @chevycam94 Congratulations :good:

I had a freeze and reboot to ram dump. Your not the only kernel. Happening on Franco and kirosuko as well. Maybe check there commits and threads too. I couldn't get log but go others that is helpful. KMSG here, https://drive.google.com/file/d/0Bw-ARc6DtAVJUHdWYnlaSmMza1k/view?usp=drivesdk. Other is attached

Could a couple of you test this kernel build for me? I'm having a fight with my build system. I'm getting 9 "section mismatch" errors, and I am scratching my head to the bone trying to figure out whats going wrong. My code built fine on my last VM, but I screwed up and killed that one. Now my new setup, same OS, same toolchain, same code, builds with 9 errors. I have to force it to ignore those errors (which I didn't have to do before), so I have no clue if this even works now. I would think it would, seeing as the code was functional before, and hasn't been changed since.
Test the crap out of it. I know it still has the regular issues some other kernels have, but it should otherwise be fully functional.......SHOULD
UPDATE: I managed to find some time to test it. So far, it's working fine. Some things spam the crap out of logcat, but that's ok. Compared to the stock kernel this is instantly faster. HUGE difference. Wasn't really expecting it to be that noticable. Nothing has crashed so far. If all goes well, I'll start work on the next release. v1.0.9 isn't meant to be a public release BTW. It's simply in the testing phase. But if you like it, feel free to use it! Just know that it's not officially supported in any way.

PERFORMANCE TWEAKS:
Use these tweaks to really get some kick....um....butt, performance from your Pixel XL! I'm on my v1.1.0 kernel (unreleased), but it's essentially the same as the v1.0.9 zip I just posted for testing. HUGE difference in the phone!
Chage the following items to the given values:
Code:
dirty ratio: 40 (default=20)
dirty background ratio: 10 (default=5)
overcommit ratio: 35 (default=50)
swappiness: 40 (default=60)

You can find them in the 'Virtual Memory' section of whatever kernel manager you are using.

Honestly, I'd spring the money for EX Kernel Manager. @flar2 has made a nearly perfect app to control just about everything you could need. It's not designed to be a "toolbox", but rather just a place to set options for the system, kernel, cpu, gpu, and memory, for the most part.
He still needs to update the live CPU display on the main page, as its not accurate, or even right (at least on the Pixel). Along with odd CPU frequency selections (they dont always become what you select, depending on kernel/setup). There are one or two other things, but I don't remember off the top of my head.
But regardless, it's the best kernel control app I know of right now. Most friendly for me. Also give you widgets/notification icons for "performance mode" and "power saving" mode. Quick toggles. Love that part.

Battery life is about the same, or slightly better. At least for me. Depends on your setup.
