Could be worth mentioning the .IMG file can also be flashed using Flashify without having to connect to computer at all.

pretty and nice
Running almost perfect in CM12
Waiting for OC I know you can do it,I use run the shaky156 OC 2.499 kernel for almost 1 months with no problems and I switched to CM12
Thanks and keep the nice work

Anybody can give me feedback about battery on CM 12 / 12.1 when device screen off (deep sleep), please?
Thnx!

The - latest wifi ROM- version you uploaded in the CM12 thread also includes your kernel as presented here?

Is it possible to include colour profiles in the kernel? Love it on my nexus 5! Looking forward to seeing this move forward
Also is there a rest of world lte version in the works? Thanks

Yes, I always compile CM 12.x with my kernel version. The 12.1 is totally experimental.

Take note for colour profiles but I don't know how complex it can be... I'll be studied, sure.
About LTE RoW (wx_un_do) vs LTE US (wx_na_do) they are totally compatible as @Steel01 and me have seen. I have LTE RoW model and actually use wx_na_do compilation. In the future, perhaps, we will create a specific branch.

I will be away a few days so a lot of sleep time for the tablet Will report

Here's some cpu state time info for u. 51mhz is deep sleep right?

With CPU Spy you get how long the device is in deep sleep: http://forum.xda-developers.com/showthread.php?t=1011497

Cpu spy capture for u. I've been running it like I stole it all day.

I don't have installed CPU Spy but BBS reports that it sleeps like a baby.

Got a spare apk for bbs by chance?

Download Better Battery Stats XDA edition here http://forum.xda-developers.com/showpost.php?p=15869886&postcount=2

Just wanted to let u know the mic issue was a gapps thing, the minimal edition has problems, went back to pagapps (the final 03/15 one) and if I flash this kernel on steels cm12 it works perfect. No sound fc either. The ONLY issue I found is moving to SD. Still says no room even after the folder mount patch. Battery is great btw, thanks much for the work

Is it possible to add double tap to wake / sleep? ☺

[Repack][Kernel][Mido][06/05/17]

Preamble
​
Hey everyone!
Xiaomi JUST released their source on 17/5/17 for mm. THAT IS SO DAMN COOL, THE WAIT IS FINALLY OVER. You guys can expect a custom kernel from me sooner or later(i'm busy). However, if the custom kernel really comes out from me, it won't be on this thread. This thread will maintain active development though, repacks of other custom kernels!
What is a repack? A repack is essentially, in layman terms, porting a kernel. I can run a kernel for AEX on RRN and stuff like that, but please do take note that my repacks are tweaked towards battery life, while keeping some speed. I might add bonus scripts in future, but for now, i'm just trying to get this up and running.
Please flash at your own discretion. I try my best to test at every release, but sometimes i just don't have the time to do so. I have homework and revision and all,and i need sufficient sleep for growth(i'm 13) so just bear with me. I am NOT responsible for anything that happens with your device

FAQ:
How to NOT break safetynet?
- Just flash the build after the flashing the rom. You can flash mods like magisk and systemless supersu that does not modify /system
Why did i lose my root after flashing(SuperSU)?
- Because supersu patches boot.img and adds a script to start the SU daemon. Flashing a new boot.img will cause the script and patches to be overridden. Just flash the supersu zip again and everything will be reapplied
What can i report?
- After testing a build for a specific rom, you can state the rom your device is on, how old your device is, then the thing you wanna report. You can report failed boots, function bugs and SOT(battery)

Got any examples of what can be added in? I assume it's mostly ramdisk related since the zImage can't be modified.

yesh. and the ramdisk will be tweaked accordingly
like i can optimise governor values and stuff. the real development will start once sauce gets release(SAUCEEEEEE)

Welp, is there any way to obtain the voltage values per frequency from there (Reading the values, not changing it)? I wanna read it and make a governor tweak.

f im not wrong voltages are inside the kernel source, no way to change that if the kernel does not support it(its not by default)
Governor tweaks can be made. Values are found in init.qcom.rc

yeah...alot of stuff comes packaged if the kernel supports it(qc, voltage, more governers) but currently, the kernels from xiaomi are not meant for any customization, thus what i can do is to tweak whats currently in store. I cannot add features to the kernel now. I can only tweak the available features The real development starts when the sauce gets released

Heh, even with the kernel source I still can't add QC into my Xperia. It's a good thing the Note 4 has more devs. Also, are you experienced in kernel building?
The Carbon Rom that popped up last night listed Mido kernel sources, which I'm highly sceptical if it works. I just need someone to confirm since the OP isn't responding.

from what i know, i suspect it's a partial source. That means that its not full, and there will be some limits
Pertaining to your first question, i can and will build kernels, but i will only do so in December, because my school projects require windows and linux would me more ideal compared to bash on win(always get that dpkg error)

where is the download link? oh, this is just pre-release?

[Kernel] Project T Kernel for ZTE Axon 7 Mini

Hi guys,
I know that this forum is not widely used by ZTE Axon 7 Mini owners, but I still want to share my work the kernel used by the stock firmware.
Most of the parts were of course already based on the work of others, so I will give credits at the end of this thread of course.
Pre-requisites:
Unlocked bootloader
TWRP flashed
Knowledge you do this all at your own risk! I tested this kernel with my EU model, so I don't know if this will work on the US models, too.
Features:
- Based on latest kernel source shared by ZTE (ZTE B2017G Nougat(7.1.1) Kernel(3.10.84))
- Built with GCC 4.9 toolchain
- UC to 499MHz for BIG and 403 MHz for LITTLE (thanks to @flar2)
- OC to 1651 for BIG (again @flar2)
- Additional governors: yankactive, blu-active, impulse
- Additional IO schedulers: Sioplus, Zen, FIOPS. Tweaked Row is set as default
- Additional TCP congestion algorithms with westwood being the default one
- Approx. 30% faster due to CRC calculation and auditing disabling
- Sweep2Sleep on the navigation bar
- frandom RNG
- Sound Control by @flar2
- ZRAM using LZ4 optimized for ARM by default
- Optimized power management driver by @Yank555
- Native exFAT support without needing fuse @dorimanx)
- KCAL
- Vibration control
- uses higher power CPUs to boot (got roughly 3s faster boot time)
- Dynamic Fsync
- Gentle Fair sleepers can be toggled via sysfs and Kernel Adiutor
- Smaller tweaks
To do:
- Switch toolchain
- Remove "dirty" from the kernel name Apparently I need to push all changes to github before compiling(or recompiling the same kernel as soon as I pushed everything)
- Set the phone to accept the lower frequencies without having to set this up in Kernel adiutor
- Alter interactive governor to use full frequency range
- Add D2TS for screen and fingerprint sensor, S2W
- Wakelock reductions
- Maybe BLX, KCAL (even though I don't get the point to implement it) I was curious and did it now, looks nice
- LED and vibration control
- Switch hotplugging mechanism to Lazyplug, hotplugging is not that energy efficient anymore
See the attached picture regarding the CPU stats when using yankactive for example
Credits go to:
@Lord Boeffla @flar2 @dorimanx @Yank555
Unfortunately I didn't give proper credits on my github, I want everyone to know, that none of the features were designed and written by myself, just adapted to work on our phones!

Changelog
V1.1: Initial version for public release!
V1.2: KCAL support
V1.3: Changed boot CPUs to higher power ones, added dynamic Fsync, added Quick Wakeup driver
V1.4: Gentle Fair Sleepers can be toggled now, ROW scheduler tweaked

I wouldn't exclude this, but as I am running on stock, I can't confirm or deny...
You could make a backup of your boot and flash it and see what happens, worst thing is that you need to reboot to recovery and restore your backup

Thank you for replay, what governor you use?

You will need to try and see.
It uses anykernel which is good. But aokp and lineage are on android 7.1.2 while stock is on android 7.1.1. There was at least one kernel api change that may cause problems. But I'm not sure.
I'm assuming this package has the wlan module also...?

You mean the prima wifi stuff I have seen in you github? Honestly I didn't feel the need...does it improve the wifi experience or is it just for making it compatible with LineageOS?

No, I mean the kernel module for wifi, /system/lib/modules/pronto/pronto_wlan.ko. If that doesn't match your kernel, it won't load and you won't have wifi.
Note stock has a handful of other kernel modules, but I don't think any of them are needed Most look like they are for testing.

Oh, ok...pronto driver is built into the kernel though, all other modules are really for debugging and testing as far as I could gather, so they are not included (and the phone works fine)
@Askael: As for a custom kernel for Lineage/AOKP etc: as I won't have these OS's on my phone I use as my daily driver, I can of course create one, but it is always published as untested, so there is no point IMHO.

[KERNEL][EAS][O2][UBER] Chihayafuru Kernel v0.90 Honor 8 for Android 8.0+

Chihayafuru might feel like an awkward name for a kernel, but the meaning is pure and beautiful. Inspired from an Anime series, the name means "do towards good direction powerfully" like a "thousand swift swords". That's exactly what this kernel is.
This kernel has been made with love by cherry-picking commits from most of the work already done by other developers and introducing other slight changes which ensure your device gets the love it deserves. From performance to battery saving options, you're in full control of your device and the plethora of configurations available allow you to tweak it to your needs.
Presenting CF Kernel (ver 0.90) for Huawei Honor 8​
Compatibility Notes:
This kernel is tested to work with stock EMUI 8, Treble 8.x and 9.x ROMs. Compatibility with other ROMs is not guaranteed, However, this doesn't mean I won't support them. If you face a bug or issue, please report it here and I'll happily take a look at it.
GPL Notice:
This kernel conforms to GPL license requirements. Thus all the source code is freely available here without any charge: https://github.com/hackslashX/android_kernel_hisi_hi3650
Recommended Apps:
To tweak most of the settings in the kernel, I recommend using EX Kernel Manager: https://forum.xda-developers.com/general/paid-software/app-ex-kernel-manager-t3560850, Kernel Adituor: https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=en and FK Kernel Manager: https://play.google.com/store/apps/details?id=com.franco.kernel&hl=en
Early Release Notice:
The kernel is still young and not yet mature. However, with time and your support, we can help make this project rock solid stable for Honor 8. Even though my initial testing has proved good, things might break on your end. Don't fret when that happens, take some logs and send it to me so that I can take a look at them and attempt for a fix.

Thank you for your work
And i hope someone running android pie gsi can test this and see if it fix the overheating problem

Thanks a lot <3

Trying it .. will let you know, if I hit any issues

Does it affect the root after flashing this kernel?

No root is not affected after flashing this kernel.
The kernel image only modifies the 'kernel' partition and leaves the 'ramdisk' one as it is.

Thank you hack slash for your support for having the honor 8 finally have a custom kernel, it works very well for me
I Flash the custom kernel using twrp for my honor 8, it went very well,
Performance is nice, I notice some speed improvements in games and also battery Improvment.
Im waiting for Undervolt now and the battery would be awesome!!!

Thanks for your review.
For gaming you can also set GPU governor to Performance for a more better experience.
I've noted down your request. I'll do my best to deliver.

I never flashed custom kernel before. Is there any chance of permanent brick? If something goes wrong, can't I just flash stock kernel and get it working again?
Also, do I need to wipe data after flashing kernel to see the changes?

There's no chance of permanent brick. Restoring is as easy as flashing the stock kernel via fastboot.
You don't need to perform a data wipe. However, you should allow the kernel to 'settle' i.e. use it for 2-3 charge/discharge cycles to see the effect.

@hackslash .. Installed it yesterday, seems to be working fine.. Jus wanted to check, I m running LoS B5, any specific recommendations on the Governor setting for battery?

I'm using openkirin RR b2. Recent Openkirin on H8 seems to have the problem to barely go into deepsleep or not anymore at all after a while. So I suffer from a quick battery drain. The support channel suggested to try out a custom kernel. I wonder if you know that this kernel will solved the problem?
How about future openkirin or kernel updates? Will I have to go back to stock first or can I just flash new openkirin while still being on this kernel?

Thanks for your hard work! I recently flashed it and it works like a charm!
UPDATE 1: I redownloaded the EMUI 8 package and now it contains everything, including the stock kernel.
UPDATE 2: Short-term experiences: The fingerprint scanner's performance is drastically improved and now it is just as fast and accurate as on EMUI, the camera performance is now closer to EMUI, but there's a little room for improvement, the fast charging is faster than on EMUI, the phone doesn't want to overheat anymore on my custom ROM and overall the phone is now a little bit faster. I'm testing it with the Kirin-GSI AOSP Android 9.0 Pie ROM, not with an OpenKirin ROM, but it is really stable just like on EMUI and OpenKirin ROMs. And I have a suggestion for bugfixes for Honor 8s (eights) running this AOSP Android Pie ROM: Please fix the broken hotspot function in kernel level on Honor 8s (eights) running this custom firmware, implement the EMUI camera app into the kernel and make the camera performance identical to EMUI's. The Kirin-GSI project is now abandoned because the dev bought a new phone which is not a Huawei phone, so he wouldn't fix the problems anymore. It's really annoying that I can't share my unlimited cellular data to friends or to my PS4 when I'm on vacation.

Damn. Now my touchscreen is no longer working. :crying:

Have you managed to back up or download the stock kernel image? You can flash it back.

Have you used fastboot or TWRP? If you used TWRP, you need to flash back the stock recovery and the stock kernel, then you can try again flashing CF via fastboot. Flashing with fastboot makes different results than flashing with TWRP.

Noted. I know what's causing the issue. I disabled several touchscreen drivers since not all of them are needed for Honor 8. Flash stock kernel for your device and please send me the file:
Code:
/sys/devices/platform/huawei_touch/uevent

Thanks for taking the time to review the kernel.
Let's get some facts straight. First, camera performance has nothing to do with the kernel and 'camera app' can't be implemented inside the kernel. That's not how things work. Camera processing and everything is handled by Android and so your ROM developer can help you with that. Taking about hotspot, I'm not sure why it doesn't works with Pie. Again, I believe it's a ROM bug and has got nothing to do with kernel. I would wait for Pie releases by OpenKirin team and see if that bug exists there too and 'really' requires a kernel hack to fix it.

Nethunter kernel for android 11

I slightly modified and compiled the kernel from tImIBreakdown, put it in .zip installer. It doesn't have overclocking and lots of governors or i/o schedulers, because I couldn't find a kernel supporting them on android 11. If you want to help me, I will be very glad.
My Changes:
The conservative governor is enabled
Added Nethunter support
Minor changes to the dtc for the compiler
Several patches from Undermind
Install: flash the zip file through custom recovery
If this caused a bootloop, then you can format /system and flash the firmware again, and since you did not format /data, your data will be saved.
Tested on Arrow-OS 11 and crDroid 7.18
Source code:
Github: github.com/tImIbreakdown/android_kernel_leeco_msm8976/tree/lineage-18.1

The work is in progress... wait...

Is it specific for Android 11 or does it work also on Android 10?

I do not know, but I am doing this on a fork of the lineage 18.1 kernel from tImIbreakdown. I can try after this kernel to make another one on kernel 17.1 if it won't work on android 10.

Thanks. There is a big issue with the lineage kernels: the GPS lock time is very, very long.
On oldest kernels, I mean the ones affected by the echo in call issue, the GPS lock time was fast.
So, as usual, one issue fixed and a new one introduced.
I wonder if you brand new kernel is just a tuning of the governors or could affect also the GPS driver.

Сan you send me the version of your firmware and kernel? Maybe I will be able to transfer the GPS drivers from there to the new version.
It will be much better if you also find the location of these files and show me the source code of the kernel with a high-speed GPS. Here is an example of the kernel source code on which I make this kernel: (github.com/tImIbreakdown/android_kernel_leeco_msm8976/tree/lineage-18.1)
I am now seriously busy implementing hotplug and about 20! new governors.

To tell the truth, I didn't understand your problem very well, I use a translator and it distorts the essence. Tell us in more detail.

OK, sorry. I've just investigated further and the GPS issue seems related to a wrong default gps.conf and not to the kernel itself, although the GPS signal is quite weak.
So go on with your kernel development and, when you have finished, I will try it.
Thanks
