[KERNEL][G900H] duki994 Kernel [LP][STOCK]

duki994 Kernel for Stock TouchWiz LP ROMs

A personal project that had good results and I wanted to share it with others :)

It's based on official Samsung sources for Lollipop firmware.

Important note:
This kernel should work on any custom ROM that is stock lollipop based and is based on stock BOL2 source

Features:
* Wolfson Audio control adapted to G900H implementation (thanks to @AndreiLux)
* Battery charging control (thanks to @AndreiLux)
* CPU voltage control for both A7 and A15 cluster (thanks to @AndreiLux)
* Exposed all OPP voltage controls (thanks to @AndreiLux)
* Powersuspend v1.7 by @faux123 and @Yank555
* MM and FS powersuspend mods ported from @dorimanx's LG G2 kernel
* SCHED code fixes
* SCHED: HMP thresholds changed and new patches implemented
* OF code updated --> better/faster reading of DTS and faster operation
* Many changes related to ARM instruction code and lowlevel ARM core management
* Enabled NEON mode in kernel with full VFPV4 support
* Added new SHA256 , SHA512, SHA1, ASH2 and AES NEON accelerated algortihms - now blazing fast
* WiFi standby wakelocks (PNO wakelock) reduced
* WiFi userspace power mode/DTIM change (for advanced users ONLY)
* WiFi driver switched from deprecated earlysuspend to use newer powersuspend driver (this is to fix some of bugs that could lead device kernel crash)
* WiFi: fixed enormous battery drain during standby/suspend
* NET updates
* LMK updated and added new feature: Adaptive LMK --> better multitasking
* Enabled all TCP congestion protocols and set Westwood as default (best wireless performance)
* Disabled KNOX
* Wakelock disabler: You can disable some common Samsung wakelocks in Synapse "Misc" tab if some of them are draining your battery
* Fully configurable in Synapse (download from Google Play)


/* Important note to other devs */
You cannot include this kernel in your ROMs. I can't be responsible if anything goes wrong, I can't help with any issues without knowing kernel version and users should be routed to this thread if they want this kernel, or if you recommend it. I think that it's best to separately view custom ROM and custom Kernel, so each dev (ROM or Kernel one) can work on bugs/features and make it as compatible as it can.
However, you can add this thread link and mention me in your thread, as so people would know where to ask if kernel problem arises. I would do the same for you :)



Warranty void
By flashing this kernel you will void your warranty. I'm not responsible if you brick your device, or if someone starts nuclear war.

Note:
Don't change voltages on "Busses" tab if you don't know what you are doing. It can reboot your phone if your memory controllers, ISP or MMC controllers that can't handle low voltage.


If someone happens to have bug with WiFi saved password being lost every reboot, here is fix:
WiFi pasword resetting fix:

Code:

---

1. open your build.prop file
2. find line ro.securestorage.support
3. change it from true to false (if not already false)

---

This line being on true CAN make your WiFi forget password each reboot. This is due to Samsung's rooting restriction and other Samsung specific workarounds to stop rooting and flashing. Any custom ROM probably has this line changed to false.

Known bugs:
* Turning headphone EQ on will lower headphone output volume.
* If you set any of Headphone EQ bands to 3dB, Wolfson audio chip will produce very unpleasant noise and stop playing.
It seems that it's inner HW components don't like that gain.
Every other setting will work, just don't set any band to 3dB :D
* Charger controls for AC current are not reacting to change.
->working on it.

Special thanks:
@AndreiLux for his awesome Synapse app, audio control, charging control, sources and many features/updates and upgrades to Exynos kernel code
@UpInTheAir for his source that I looked when I had bugs, and for his fixes/workarounds
@halaszk88 for his source that I looked when I had bugs, and for his fixes/workarounds
@dorimanx for inspiring me to start developing and his mods
@apb_axel for UKM and his scripts that helped me a lot in making custom Synapse config
