[KERNEL] Sphinx Kernel [10/11] [4.9.261] [Clang 11] [13.03.2021] v3.6

milouk · Nov 2, 2018

Introduction
Ahoy everyone,

I decided to share my personal custom kernel with all of you. The main reason i started developing this kernel is to balance performance / battery / security and also add features.

I believe i have included most of the usually requested features. If your feature is not included you can ask for it and i will try to include it as long as you don't ask for ETA's. I am a student and i do this on my spare time.

Pie kernel is based on LineageOS 16.0 sources for beryllium and is compiled
with SdClang which is Qualcomm's LLVM Compiler for extra performance. [EOL] - Final Version is 3.1

10 kernel is based on LineageOS 17.1 source for beryllium and is compiled
with latest sources from LLVM for Clang 11.

So let's jump to the interesting part!

Notes

I bear absolutely no responsibility. If you brick your device. If you are not sure what a kernel is, how to flash it or how to restore your phone in case something goes wrong then do NOT proceed.
Moreover, you should flash this kernel only over the stock kernel that came with your Rom.

Previous Versions

Version 1.7

Ahoy Ladies and Gentlemen.

Time for new version!

Changelog:

1) Upstreamed to Linux Version 4.9.135 - Better Security / Stability / Performance
2) Merged ext4 upstreamed commits - Better System Performance
3) Merged Lineage 16.0 Upstream commits - Better Stability / Battery / Performance
4) Now Compiling with Uber Toolchain 6.4.1 - Better Battery/System Performance
5) Added Zen v2 I/O Scheduler - Better I/O Performance
6) Added TCP Congestion Algorithms (bic, cdg, cubic, westwood, htcp, hstcp, hybla, vegas, scalable, lp, veno, yeah, illinois) default is cdg - Better Internet Performance
7) Improved msm_performance - Better Performance
8) Enabled USB Fastcharge up to 900 mAh - Note (1)
9) Added blu_schedutil - Note (2)
10) Makefile Optimizations - Better Performance
11) Added LED Notification Control- Note (3)
12) Enabled LZ4 Compression Algorithm for Zram - Better Battery / Performance
13) Now Sphinx comes Pre-Configured out of the box for balance
14) Support F2FS File System - If Rom Supports it -

Notes:
Note 1: This is USB Fast Charge which means it works ONLY when you charge from a computer. The default output was 500 mAh and now it's 900 mAh (which is the maximum a usb port can support)
Note 2: This is a new EAS Governor ported from blu_spark Kernel for OnePlus 6. Currently it is almost the same with the schedutil governor from Pixel 3
Note 3: Many of you made some comment about the LED Notification being brighter etc. Now you can configure it yourself. THOUGH there is not interface for that in ANY App, you need to do it yourself.
Specifically:

Code:

     *  /sys/class/leds/white/device/led_fade (rw)
                        0 : blink
                        1 : fade (default)

     *  /sys/class/leds/white/device/led_intensity (rw)

                                        0 : stock intensity
                        1-100 : 0% to 100% of stock intensity
			Note: Does only work for static led, not fading/blinking !!!

     *  /sys/class/leds/white/device/led_speed (rw)

                                        0 : stock speed
                                        1 : continuous notification light
                         2-12 : 2 = very slow to 20 = very fast

I have listened to your requests to bring Sphinx to Poco and did everything in my powers to satisfy most of you and ensure this version is stable so if you enjoy this version don't forget to buy me a coffee

Cheers :highfive:

Wow, Amazing. Can i flash this on stock miui beta 8.11.1 also
Great work.
Edit :
Just installed , super smooth. Everything works great so far. Antutu 291328. Not sure if it is placebo but face unlock seems to be faster, haven't been able to see lock screen in the trials I have done so far.
Rom is stock beta 8.11.2 and no root yet.
Will root and tweak with suggested ex kernel manager and report

Of course you can mate

frequency on big cluster is max on blu schedutil whilst on omnirom

bla.blub · Nov 2, 2018

thanks sounds really good gonna try it right after i flashed 8.11.1

Its how it works. It maxes the big but it lowers little cores. Currently its almost a direct copy from Pixel's 3 schedutil. If you dont like this behaviour i would suggest regular schedutil. Regarding blu_schedutil you can read more on its original thread "blu_spark kernel for OnePlus 6"

Awesome. Its a direct port from his kernel.

you absolutely sure its supposed to stay at 2803mhz constantly that is a huge power drain and makes no sense?

What im saying is that i picked the code EXACTLY like it is. Its 99% the same as Pixel 3 schedutil. Also youll notice that the battery drainisnt at all as huge as you think.
Morever while merging there wasnt even one conflict the code is 100% correct and exactly as eng.stk wrote it. Ifnyou have questions about the code im not the person to ask no offense. Im not taking the credits nor the blame for someone elses work. I just think its a nice addition especially for users that need performance.

Also as you may have noticed its not the default gov for that exact reason.

**Also of course there is always the possibility to remove a feature if i see no one finds it usefull.

Btw i always listen to feedback and try to satisfy most of you.

Cheers
