[KERNEL][Z3] 78Kernel v3

[Gustavo RD78]

Here is a kernel we would say pretty much stock built through the sources

Build kernel from clean sources

Add features ramdisk:
busybox auto-injection (/system/xbin)
init.d support - automatically creates init.d in (/system/etc)
twrp-sony-recovery-boot-script based (Thanks @nilezon /jackfagner github script)
TWRP recovery 3.0.2-0 Modified (vol up or down when White LED)
Removed SuperSU in TWRP recovery to root because this method will not work
Systemless root support
SElinux permissive
Debugging enabled by default
Disable debugging notification icon in the status bar
Kernel insecure (ro.secure=0)

Add features Zimage:
Build with Linaro 4.9.1
Fix all errors and compilation warnings
Add voltage CPU control
Fade in/out led notifications. Thanks to @v-yadli
Implement sysfs interface for vibrator intensity (set to 23 as default, change)
Enable toggle for CRC (stock Y, change)
RIC disabled
Add and set as default Auto SMP hotplug with some mods
Add controls for optional scheduler features. Set both, arch_power and gentle_fair_sleepers to disabled by default


Note that not all resource requests will be granted, this is a custom kernel built for my private use
But I'll be ready to the experience you have with some other kernel and / or feature that will bring improvements

* Required Bootloader Unlocked!

* Installation:
Downloads:
78Kernel_v1
78Kernel_v2
78Kernel_v3
-Flash via recovery or unpack and flash boot.img via fastboot

fastboot flash boot boot.img

* Root:
-Flash a Systemless SU: SuperSU-v2.78-SR1
Note:
- The first boot may take some time, and give the impression that you are in a bootloop. Just wait and it will boot up normally eventually.

-Flash DK.ftf
or
-Flash Restore DRM - SONY DRM FUNCTION RESTORATION FOR UB DEVICE

78Kernel_v1 initial build from sources (23.5.A.1.291)
78Kernel_v2 build from sources (23.5.B.0.303)
78Kernel_v3 build from sources (23.5.B.0.368)
*Add and set as default Auto SMP hotplug with some mods. IMPORTANT: Need to disable mpdecision in order to avoid conflicts
Open file /system/etc/set_governor.sh and delete line:

start mpdecision

*Add controls for optional scheduler features. Set both, arch_power and gentle_fair_sleepers to disabled by default
*Removed ANDROID_LOW_MEMORY_KILLER_CONSIDER_SWAP, Implemented in firmware .291 that causes swap zram problems full lag device

Nice one brov..... Im getting tempted to unlock my BL!!!

 

[Beetle84]

Working well on fragment ROM V4.0, thanks mate, will report if I come across any issues, but flawless so far.

i dnt know whats wrong...... unlock BL den flash tha kernel & Fragment rom, when it boot up no sign of tha kernel in kernel version so i reflashed tha kernel (via fastboot & recovery) but when tha phone boots up, it keep restarting!

Probably a problem of combining rom with the kernel
Try flash rom stock to see if the problem still persists

Make sure you are using SuperSU version recommended on the thread
SuperSU SR2 cause boot loop, SR3 should also be your problem

Then other problem, rom, mod or...

This kernel is build from clear sources and tested and used with clean stock rom here on my device

 

[whalesplaho]

Rom is working with stock but not stock based rom....please dev kindly look into it!

Actually, I will not do it.
The breeder of custom rom is responsible for verifying your rom and finding out why it does not work with my kernel
Sorry, my kernel is built for rom and custom rom based on non-highly modified stock, we do not know what's actually put inside of your constructions

78Kernel_v2

Sony has released firmware number 23.5.B.0.303

78Kernel v2 is built clean from this release and added all features of v1
Some of the differences is that in fw 291 has been added CONFIG_ANDROID_LOW_MEMORY_KILLER_CONSIDER_SWAP, (zram full) which for me is one of the causes of lags and or delays in multitasking, fw 303 behaves faster and responsive
Full list of changes can be checked on my github

I also have bootloops. The strange thing is that elite and stock kernel work without issues on Existenz. I know it's not your kernel fault, but could you help us suggesting what could be the problem? I was able to catch a kmsg http://cloud.tapatalk.com/s/582b9a4d6983a/kmsg.txt

Thank you!

Good day @Gustavo RD78,

there is some possibility that you can add the app shortcuts and the quick settings tiles in a next update is that I saw it in Franco.kernel and this is only for the Nexus / pixel so it would be nice to have these functions in our Z3 , Thanks is a very good job and I tried to try the first version of your kernel 78kernel_v1 and I always enter a bootloops I hope now to try this version 2 and I will share my experiences

I was wondering if you can point me to a zip or ftf for the OS this kernel is based on, all I could find was the source code for the "Domoco" japan z3's, couldn't find anything else :\

If this really has fixed some performance issues, I WANT, my phone sometimes get's really slow from time to time and I have to restart system UI or restart completely (Like worse than a SD201)
