Another kernel, you say? Yes. Popcorn Kernel (pun intended) is blatantly and unashamedly a fork of Enigma Kernel, but not without some differences. While Enigma focuses on stability and UX, Popcorn tries to prolong battery life without a major hit to performance.

Why are you using the Enigma Telegram groups? Because the development of both the kernels go hand in hand, and we have way too many groups for being such a small community.

What makes Popcorn different? Well, aside from being more battry-oriented, Popcorn also aims to be up to date with the latest CAF tags, and also the latest upstream kernel in the near future.

Use either Franco Kernel Manager or SmartPack Kernel Manager to tweak. If you find a sweet spot that you'd share with the community, please feel free to do so

Installation Instructions
- Open Franco Kernel Manager/SmartPack Kernel Manager
- Head to the "Flasher"/"SmartPack"
- Click on "Import a kernel download configuration"/"Update Channel URL"
- Paste this link in the dialog that opens - https://raw.githubusercontent.com/Sid127/Sid127/master/popcorn.json
- Click save
- Click Flash and reboot after flashing
- After the reboot, open terminal app of choice and pass the commands as
su rm -rf /data/cache[/B][/I] and [I][B]rm -rf /data/dalvik-cache

This method will deliver OTA kernel updates through FKM.

-OR-

- Download the kernel from Github
- Store it on any storage you have on your phone
- Fastboot TWRP

Special Thanks to:
@Sahil_Sonar - for being a great mentor and providing a reliable build server
@CarbonGTR - for the Enigma Kernel
@Nikhilkumar038 - for all the support, and for what little testing I needed
@malvigagan - for encouraging me into maintaining my own kernel for reasons
@ArcherTanu - for sharing his GCP server

MOAR INFO

* Requirements -
- A unlocked Nokia 6.1, 6.1 Plus or 7 Plus
- A PC with fastboot working
- Stock or custom ROM that boots
- A recovery or FK Kernel Manager

* Device heats up a lot. Can you do something?
- Maybe, maybe not. A constantly hot running device can have multiple causes, including but not limited to - clogged RAM, constantly high CPU usage, exposure to sunlight, etc. If there's something I can do to help the device run cooler, do suggest and I'll try implementing it.

* Why HMP and why not EAS?
From my own and couple other testers' experience, HMP. EAS is difficult to tune, especially when it's not the native energy model for a device. HMP has decent/acceptable performance and should be a very stable solution while prolonging battery life - which is what Popcorn aims to achieve.

* What's CAF and why should I care?
CAF stands for the CodeAurora Forum. It is like the name says, an online forum where Qualcomm releases source codes and patches for their CPUs. Qualcomm and MediaTek also implement their own hardware-specific features into Android so that the OS becomes more optimized for their respective CPUs. CAF, adds a lot of stuff that can take advantage of their CPU prowess, like better audio processing, various CPU clock tweaks, camera patches, and libs, and much more.

ayy beautiful

also reasons

 

[dicamarques]

@Sid127 Any reason for not being compatible with n7.2? Thanks!

 

[Sid127]

@Sid127 Any reason for not being compatible with n7.2? Thanks!

The code base for the 7.2 and 6.2 is different from the ones for DRG, PL2, and B2N, which is why those devices aren't supported.

 

[Sid127]

I'm back after a long hiatus (mainly due to ****ing entrances) with a new release of Popcorn Kernel!

- Rebased to fresh Enigma sources
- CAF tag LA.UM.9.2.r1-03400-SDMxx0.0
- Dropped all previous popcorn changes (they'll be back in a future release)
- Fixed VoIP and Camera (hopefully) on PL2

Also a small leak to those that care about this XDA thread:
Popcorn Kernel is gonna make its way to my UBTouch port soon (which hasn't been updated in ages)
