AKT is a collection of scrips to configure the kernel settings for controlling the QUALCOMM Snapdragon 820/821 CPUs. They all take advantage of the Interactive governor. This governor dynamically scales CPU clock speed in response to the workload placed on the CPU by the user. Depending on the AKT profile you can optimize the behavior of the governor for performance or battery on the fly without restarting the phone. I have found my sweet spot with the Ghostpepper v2.0 profile but ZHANA is another good one in the balanced section.

There are several ways to install it. At the beginning they were just scripts that had to be installed in the init.d, then a installer script made things easier via recovery. At this time the easiest way is to install and use the APK file like any other app. Just download the latest version and install it as any other APK file. Root is required. Works really well with Hellsgate.

Downloading Hellsgate v2.0 test...

Other than a new source (Linux 3.18.103), is there any difference in features compared to Hellsgate Oreo v1.3 ?

Update: I can confirm KCAL color calibration works. AKT are applied correctly. F2FS filesystem works well in Data/internal_storage and Cache partitions. Viper4Audio is vipering well and browsing is smooth. Snap camera working well too using API2. With Hellsgate Oreo v1.2.1 I had some random crashes with background apps such as Spotify. Hellsgate v2.0-Test seems more stable. No major, no minor, issues. So far so good. Your kernel is doing its stuff pretty well!!!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
also version 1.3 and 2.0 a differend for the new version i switch to stable relase source for the feat i make it more clean no speccial stuff we voltagecontroll and so on my focus is now performance and a good battery backup now i merge all caf patches then the kernel is ready for relase
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JTruj1ll0923:
Thanks bro! Running it now and it seems to work just fine. Much, much more stable. Also exFat works! It doesn't require it to be formatted as vfat, so thank you! I will do more testing over the next few days and get back to you. Again, if you need more testing let me know. Thanks again!

Kernel 2.0 is stable till now. The only thing I have noticed is huge wakelocks coming from 6a00000.ssusb
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
i face it to but its not cosuming battery i find you can disable this lock

2 Install Root Explorer app.

3 Open Root Explorer, find /sys/module/dwc3_msm/parameters/disable host mode

4 The default status when you open the file should be N Change it toY.

5 DO NOT restart your phone.

6 Wait and see.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] nfsmw_gr:
Cool.

You guys can also use ex kernel manager, it has a wackelock blocker function.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
I use exkernel manager but the waklock is not listed strange i Google this and many user in oneplus3 have it to but they have the Problem phone goes not in deepsleep but axon goes in i look to block this but the kernel is not ready i must merge now all CAF upstreams patches i think its come Form a old driver or so but i donnt face ans batterydrain Form this lock then this wakelock is present in many Roms like lineage RR and so on
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] nfsmw_gr:
I see, I was not aware of this, work at your own pace thanks in any case. :)

I'm still on Nougat myself since stock camera doesn't work on Oreo and I really need it as I use manual settings a lot.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
I also miss the ZTE Camera, but Snap camera app works fine in RR-Oreo, It can use Camera2 API, HDR mode and 4K video.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] nfsmw_gr:
Thanks for letting me know, the thing is I like taking night shots, and without adjusting iso and exposure I don't think snap can shoot as well as the stock camera can.

I'd love to be wrong to be honest haha, if it can I'll flash oreo ASAP. :D:p
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
Manual mode for exposure, ISO and focus works perfectly with snap camera, and the auto night mode too when using Camera2 API!!! Probably it is time for you to leave your confort zone and try this software. It will give you wings to fly to Oreo. This camera is really better than the stock one.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] nfsmw_gr:
Really???!!

Oh well, I may as well backup what I run and flash it sometime today, man If you're right I'll jump all over the place like Mario from happiness :p :D
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JTruj1ll0923:
So after 2 days of testing the new test version with AEX-O it looks great! It has been really smooth and no hiccups. I did have one random reboot, but I am pretty sure that was not the Kernel's fault.

Along with the kernel I am using AKT Project X.A.N.A Battery and I've had no slowdowns or low performance. My battery life, in my eyes, has been great and I don't worry about it running out so far. I played two very simple and non demanding games today so the battery life may be a bit less than other days considering I hardly ever play games on my phone.

As of right now I am at 5% with 5hr 45 min SOT with my brightness on about 25% most of the time. The only thing I can't figure out is, according to EXKernel Manager, my idle drain is over 1.25%. Not bad, just kinda annoying. Overall, looks great! Thanks [MENTION=7790189]Kranoner[/MENTION]!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
nice to hear that the random reboot i have it since relase from project new world also its 100 pro not the kernel big thanks bro for testing it :D

[MENTION=7790189]Kranoner[/MENTION] hey man, I'm using your Hellsgate test 2.0 now since yesterday. I noticed very slow read/write in internal storage. This is very noticeable when you're downloading something and installing apps (whether apk or playstore), and even when just searching for a contact at WhatsApp..

Could you help me to make the internal storage read/write faster? Which settings or system file I am should modify?

Cheers!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
i dont face this witch rom do use
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bramhc:
I'm using aosp extended (AEX) 5.4 build 20180406. Apart from read/write issue, everything is very smooth. That's a big plus ;)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
you are the only 1 all others testers reprot all is working ok
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bramhc:
Hmm maybe I should upload a video about it.. :confused:

Cause when I revert to stock kernel, read/write working fluidly as usual. But I miss KCAL, so I keep coming back to Hellsgate.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] kowallis.r@gmail.com:
No. I am having similar issues with the same setup
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
later maybe but i dont use axon7 as daily driver i use pixel2 i build it for my son his axon7 also my old phone :D
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bramhc:
What's the issue you faced so far apart from slow download speed, open up a file, searching in whatsapp, phone call? I faced a sluggishness when it comes to a task that needs to read/write from internal storage.

Apart from that, for me, UI is very smooth, scrolling very smooth too. Battery life is improving about 25-30% for me. And the phone is very cool, unlike with stock kernel which is easily gets hot.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] marcdw:
Maybe check I/O Scheduler settings. Not running AEX Oreo or Hellsgate on my Axon so I don't know what the default values are.

You can change the read-ahead size or even the scheduler, depending.

I do not have that, or any other, issue using Resurrection Remix Oreo on Hellsgate Oreo 2.0-Test. I have F2FS filesystem in DATA (including internal SD) and CACHE partitions and this Axon 7 is now a rocket using Oreo. So you can try to reformat DATA and the internal SD to F2FS using this guide or just try RR-O rom. This way you could see whether it is a filesystem issue (kernel related) or a configuration issue (bad rom settings).
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] kowallis.r@gmail.com:
No, you have nailed all the issues above.

Thank you very much!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
today i relase the final test for hellsgate 2.0 before i relase it

what is new

kernel is now up to date off 3.18.104

merge all caf patches from codeauroa

kernel build now with clang over dragontc

and many more ;)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] bramhc:
Hey man. How do you solve the read/write speed issue? I really want to know cause I really like the battery improvement and ui smoothness with this kernel.

Cheers!

bro i switch today to rr oreo with f2fs you are right the axon7 its now like a rocket thanks for the tip bro
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] aLexzkter:
After flashing the previous version of the kernel, I started experiencing missed vibrations on the hardware buttons. I didn't have this issue with the stock kernel found on AEX Oreo ROM.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
hmmm... Too many steps. I just boot recovery, flash kernel, flash the same magisk I was using, and boot to system. That's all.

I see you are now on Linux 3.18.104 and updated linux drivers for filesystem. Ensure you are using F2FS drivers backported from the Android kernel 4.10 or later to be able to use all the optimizations of the F2FS.

HG-O 2.0 finale-test works as stable as the HG-O 2.0-test, Rock solid. Thanks for sharing this excellent work.

You are welcome, just press the thanks button. I wrote that guide in 2016, when F2FS was not well known. I've been using this filesystem and the performance has always been awesome, and Oreo takes even more advantage of it. The only problem is the long time it takes TWRP to boot depending on the size of the DATA partition, then it works perfectly. It is strange since everything else is faster. Probably TWRP should update something to take care of this problem in the boot script. This issue has been in TWRP at least since 2016.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
i change alot off things bro i merge all codeauroa patches we need it for caf update fscrypt: updates on 4.15-rc4 NEON-accelerated implemt and so on

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
Sweet.

By the way, I see in your git that you are using F2FS drivers backported from the Linux kernel 4.16. There is a lot of difference in the latest implementation. The fstab mount parameters can be optimized when using the latest F2FS in the kernel. Nice!!!!! new toy to play with.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
nice to hear bro please test all things when its any inusse telle me i revert then thinks before i reales the kernel must be stable for daily use:D
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Infy_AsiX:
Hi Kranoner. A new user to custom software on the Axon 7. I'm on the latest AEX O and promptly flashed your test kernel. I'm using F2FS too and i'm noticing fast and smooth performance so far. However I'm noticing there's aggressive thermal throttling that can't be switched off in Kernel Adiutor. It's looks the same as stock starting to throttle to 1.6+1.3GHz and soon dropping to 1036MHz on all four cores. However unlike stock there's no /system/etc/thermal-engine-8996-normal.conf or anything of the like to redefine the throttling limits. I tried creating a generic file or two there to test but they disappear after restarting. Is there any way to change this hidden thermal throttling?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
oh sorry i forgott to delet it in my hellsgate.rc wait a moment i load a new zip up ;)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
Not a Kernel issue. It works fine in ResurrectionRemix Oreo ROM.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
i dont face it too but i forgoot to delet thermal driver from faux in my hellsgate rc because i dont add this driver in my kernel its a little mistake from me but its make no problems by me
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
i use only exkernel manger from flar 2 then kernel auditor gives me most wrong stats from cpu etc download exkernel manager and you will see all is ok i use since yesterday AexO too and dont face any problems right now
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Infy_AsiX:
I normally set my profiles using shell in Tasker and test with Kernel Adiutor. Hm I just tried on EX Kernel Manager and I still can't raise the max frequency above 1036MHz while it sits fairly hot on my table. Did you only forget to remove the driver on the 2.0 finale test? I'll try the R1.3.1 if that's the previous version?

Also have you considered the kernel audio mod to allow choosing the DAC's filters? I just gave it a test and though the default is a good choice the super slow extra option I find better. It loses a little volume but sounds much smoother for a more comfortable listening experience. I'd think it'd be most useful for extended listening at moderate volume without as much fatigue. https://xdaforums.com/axon-7/development/cad-project-modified-audio-driver-axon7-t3761666

edit: I noticed AEX O's kernel already has this available too.

edit2: Nevermind I found out that the file's in /system/vendor/etc/thermal-engine.conf. So it's not a kernel issue. Though editing it in the ROM still hasn't lifted the throttle... so unresolved

Used this kernel for one day on my A2017 (u) 4/128. Doesn't beat the kernel coming with DarkRom. It's fast but sometimes jerky when scrolling through pages, device got pretty hot with interactive governor, hellsactive and lionfish kept it cooler, but less performance (lionfish).
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Kranoner:
i load my device today with quick charge 25-29 degrees but today i relase a eas version from this kernel
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] nfsmw_gr:
Good for you but there is no need to do that.

(unless you want to experiment of course)

No rom out there besides the discontinued Purefusion has proper support for EAS, so it would be a waste. :/

In other news I flashed the 2.1 version so far it works great!

I recommend trying the lionfish governor alongside maple io scheduler, the battery is INSANE!

P. S. In case you absolutely need to do an EAS kernel, please make another branch if possible and keep the current one as well :)

Thanks bro

What do you use for a kernel app? I found a few of the popular ones don't all me to set the big cpu and set the io scheduler.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] nfsmw_gr:
Yeah, I had issues with ex kernel manager, no setting io scheduler both for internal and external memory, no apply on boot delay.

I only found Kernel Adiutor to work really well, tons of options, but I'd advise you to keep an eye on cpu usage because I've had some spikes with it for some reason or another.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] jarebear603:
Looks like I can change io scheduler with EX which seems to be less cpu spikey, I had scrolling stutter before when I was using Kernel Adiutor mod. Not sure if it was because of the spikes in cpu usages. But now I just use Kernel Adiutor to change screen profiles as I haven't found a way to do that in any other kernel app.

RR!

---------- Post added at 01:41 PM ---------- Previous post was at 01:38 PM ----------

You could do it by making a .sh script and execute and make shortcuts with it with script manager, that way there is no cpu spikes and the limit in changing any setting is basically limitless, the end result is very pleasing but requires some basic scripts knowledge and is generally complex and time consuming.

Great Kernel!!. I am with Dark Rom and this Kernel and Its great, but today I finded I bug, If the phone is off, charging and with the battery to 100%, and still connected to the charger, you turn it on, three seconds after starting it restarts, and so on until you remove the charger. At this point, it will not restart after turning on.

I use Ex Kernel Manager.. With the stock Kernel I didn't have this bug, I didn't try with another app Kernel

Thanks and Sorry for my bad english

Pd: I try with 95% battery and turn on without problems.. It's only with 100%

[MENTION=7790189]Kranoner[/MENTION] I noticed something funny on your kernel:

You have to flash it when the phone is cool (maximum temperature is 33° C) in order to make the kernel not having write speed problem.

I flash Hellsgate 2.0 Finale Test when the CPU temp over 38°C. I faced a horrible write speed. After revert back to stock kernel, boot it up again, then reboot to recovery again waiting the temperature to 32°C.

THE WRITE SPEED IS INCREDIBLE FAST! NO NEED TO SETUP READ AHEAD AND STUFF.

FINALLY!!! Thank you very much man ;)

Hey [MENTION=7790189]Kranoner[/MENTION]. I have been having issues with GPS lately. I am not 100% sure it is the kernel as I haven't gone to stock to check, but after a while of not using GPS I can not just get a random fix on location. Maps just doesn't know where to find me even with high accuracy GPS on until I restart my phone. I was thinking it might have to do with one of the wakelocks under the wakelock blocker in EX-Kernel Manager? Would any of those be a possible culprit of causing this?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
No problem here with RR-O ROM using latest Hellsgate based on Linux 3.18.105. Snap Camera works perfectly, so barcode scanner and Hangouts taking pictures and videoconferencing.

All I can say is that everything works fine here using RR-O. It looks like it is something related to the ROM. Do a backup of your system and do a clean flash to test what is causing your issues. If you believe it is the wakelock blocker, then just uninstall it and test. It is easy.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JTruj1ll0923:
It is from a clean install. It is a wakelock blocker built into the kernel so I know how to revert back to stock, it just isn't as easy as "uninstall it and test." But thanks! Just looking for answers before I go through the process.

Edit: So I just reread this and I hope you didn't take it offensively. I meant nothing, just trying to say it is a clean install and I was just wondering if Kranoner knew anything. Sorry for that!
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Teet1:
Clean flash does the same, perhaps it is something with AEX.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Oki:
Consider trying RR-O, that way you could have a clear idea on what's going on.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] JTruj1ll0923:
[MENTION=7790189]Kranoner[/MENTION] so I don't have Hellsgate-Test installed with AEX right now due to the GPS and I don't seem to have a problem. So if not the wakelock being blocked I am not sure. Do you have any ideas?

Also, if a log would help, what would be the best way to grab that for you? Not sure what kind of log would help most in this situation.
