[KERNEL]Sandy Kernel v1.4 [25/02/2016] [ Sandy charger control ] | [More]

My kernel would have only what's needed. However users can request a feature and if i find it worthy i would test it and add.
I am keeping short and writing the features i have added so far !
FEATURES:
V 1.4 : [ As of now only CM based ]
Switched to latest CM13 source base
Voltage control
More refined sandy charger control
Tuned elementalx governor
Darkness governor
Kcal tweaks
FIOPS & SIO added
Compiled with latest uber toolchain
Other tweaks from my end
V 1.3 :
FIOPS scheduler added
Tuneups to interactive governor
Changes to elementalx and it's tunables.
Solves potential MTP mode USB issues and sound issues.
Full synapse support added ( Doesn't directly come inside from my kernel. You will have to flash separately ). Thanks to @yarpiin
More thermal changes
Lot more in store
To download synapse flashable zip refer third post
Please install CM camera next mod which is also available under downloads section. Just install it as normal apk. Hotplug has video rec freeze on stock OP camera. Blame Oneplus for it.
V 1.2 :
Sandy charger control. Now charge your op2 much faster than stock ( Use synapse or updated kernel adiutor app [available in my downloads,not playstore of kernel adiutor] to enable it and control )
Intelliplug. Use it wisely and according to ur usage
Initial support to synapse ( The bulk needs to be still controlled via Kernel Adiutor )
Initial attempt at porting Faux Sound control ( It's not working completely yet. Will be fixed soon )
Merged with latest Oxygen 2.1 source
Plenty of other features hidden.
Initial release :
Compiled with Sabermod gcc 4.9 toolchain
Powersuspend with different modes
USB Fast charge
Intelligent cpuquiet hotplug framework ( Based on NVDIA and tuned to msm )
ElementalX governor from flar ( with latest patches )
Kcal control ( colour control driver by savoca )
Fsync on/off support
BFQ I/O scheduler added
Thermal code tweaked heavily ( device should stay at it's coolest )
Optimized for best performance and battery ( you can get some of the best results )
Smoothness guaranteed
Rcu,sched,mm and other various enhancements
There are plenty more hidden ! Just use and experience the kernel. Don't forget to post your reviews
I can only say that you can get one of the best experiences with probably no real bugs !

FAQ's
Q : Will this work on all ROM's ?
A : It will work bugless in Oxygen OS, but could give you bugs in CM or CM based ROM's ( as they are under alpha stage )
Q: OMG ! Baettaryyy SUCKZ ! STAPH putting lame kernels
A : My kernel is intended for battery and performance. I have no intention to build a kernel for battery draining. Your drain comes from your location apps,wake locks,etc. Use App ops or servicely app and check damn wakelocks & keep awake of your apps ( Play services, Maps, facebook,etc )
Q: What governor do you suggest ?
A : I have included only one governor ( elementalx ) other than stock and hence i would suggest you switch to it if it's not pre-switched after flashing.

Tested and all I can say is to flash that s#it!!Smoothness overloaded.Awesome power management!

Gotcha, definitely appears to be the most competently developed one we've seen thus far.
Am I to assume that the lack of included governor list indicates that it's the same as stock? I could really dig me some smartmax..

Kernel with exfat support and mtkcamera for Dirty Unicorns 6.0.1

Dirty Unicorns 6.0.1 is probably the best marshmallow rom for amami so far , although it has some problems: camera app cannot take pictures at 20.7mp, and exfat-formated sdcard is not supported.
So I made a kernel to fix these problems. You can flash with twrp or flashfire.
Kernel_Amami_AOSP_6_20160709.zip contains aosp kernel built with exfat-nofuse and some other features, as well as other executables or libraries needed to identify and mount exfat(vold , blkid etc.) This may work with other aosp 6.0.1 based roms, but I never tried by myself.
2016.06.18 : I ported some features from other kernels like M5 kernel. Features included:
1. Various cpufreq governors, hotplug drivers and i/o schedulers
2. KCAL color control by @savoca
3. Faux Sound Control V3
4. CPU/GPU OC & UV
5. Vibrator intensity control
6. Ultra-ksm
7. Kexec-hardboot
8. Dynamic Fsync 1.2
9. Mac80211 injection patch and HID patch for keyboard support
10. Sysfs interface to Enable / Disable CRC on the data blocks
11. Exfat and Paragon NTFS(UFSD)
12. Zram
13. Merge upstream patches up to 3.10.102
MtkCamera.zip contains camera app from Mediatek devices with lollipop. It can take 20.7mp photos(3936 x 5248) and has some useful features like visual effects and qrcode scanner.

If you're interested, Myself5 is willing to release M5 for Amami, but needs a maintainer, since he doesn't have a Z1c anymore. Maybe you can work with him on M5 for AOSP...

I've already ported a bunch of features to aosp kernel, just check out the commit history.
What left to be done : GPU governors, A few hotplug drivers/cpufreq governors not ported(hotplug : alucard , mako , intelliplug , cpufreq : HYPER, OndemandPlus, Nightmare , ElementalX, maybe more) , some of these features need to be modifeid or abandoned.

Hi, I install this, work well, but camera still laggy . What do you think, how else you can improve the image processing? The picture was much too sharp ... but it's better than before.
And...you can also add in your kernel any functions like as KryptonianKernel or AdvancedKernel

Laggy camera is a driver issue, just wait until sony updates software binaries for amami.

Hmm, why you delete MTKCamera? You have another app for taking photo in 21mp?)

MTKCamera cannot use frontcam. I think @SpiritCroc will try to add 20.7mp option to SnapdragonCamera, so wait for a new release.

need help - CPU GOVs and frequencies
Hi,
first of all thanks for the kernel! I'm just migrated from RR Lollipop to MM DU ROM (today to the build of 17. June). I have strange issues with the kernel.
I can not change the CPU govs. More critical: The minimum CPU frequency is shown to be 1.8 GHz. Whatever I try, I cannot get the values gov/freq to stick.
Always when I reopen an tuning app, the settings are reverted.
Root seems to work fine. Also tried to disable SE-linux via terminal ("setenforce 0"). The same.
(Combinations I tried: kernel audiutor, performance control, system tuner... also on DU (3. june) + kernel (5. june)
Can somebody help me out?
Who can permanently adjust the CPU settings on DU with/without this kernel?
Thanks in advance!

[KERNEL][LineageOS 13/14.1] Steel 6/7 Kernel

-STEEL 6/7 KERNEL-
This is my kernel based on the LineageOS stock kernel! I try to keep it as optimized as possible while adding a few features here and there. Suggest or request features, I don't care as long as it's logical. I hope you like it! Everyone has a different taste though.

ZaneZam, Lord Boeffla, Yarpiin, anupritaisno1, Pranay Narang, FranciscoFranco, the XOS team, LineageOS, osm0sis, aviraxp and maybe a couple others, i'm sorry if I forgot someone!
-FEATURES-
• CPU underclock to 302mhz on big and little clusters.
• GPU underclock to 27mhz.
• GPU default governor is simple_ondemand.
• Zram disabled.
• CPU Governors: interactive, ondemand and performance.
• Franco wakelock blocker.
• SLIMbus overclock.
• Fingerprint boost.
• Kcal control.
• Spectrum support with 4 preconfigured profiles.
• Headphone audio boost.
-DOWNLOADS-
Google Drive
-COMPATIBILITY-
It is most compatible with LineageOS 14.1/13 and most ROMs based on it. It should work on AOSP/CAF ROMs but not all features are guaranteed.
-BUILD INFO-
I use UBERTC 4.9.4 and Kubuntu Linux 17.

No, and won't be because this kernel has too many changes to work properly with the app. I apologize if this is inconvenient. It has been working fine with Kernel Adiutor all day for me though. :fingers-crossed:

Just uploaded an update, I added touchboost back, I removed Boeffla sound and Boeffla controls altogether. I basically refreshed the audio system, still based on PDesireAudio 10.0 due to issues with 10.1. The default IO readahead is now 128kb.
Edit: This kernel works with SuperSU and MagiskSU just fine. I've tested MagiskSU and it passes safetynet. SuperSU doesn't pass safetynet.

I'm working on adding LZ4 Fast compression/decompression to my kernel and I was wondering if anybody who may see this could help? Any tips or info are welcome, I'm trying to learn as much as possible.

I don't plan on doing that so I just removed it. The boeffla config app doesn't provide all the options and functionality that my kernel has so it's really bottlenecking it's array of options. The kernel works fine, flashes fine and builds fine as it is and I see no reason to hold it back in such a way. I based this kernel on Boeffla kernel for a good reason, compatibility with ROMs and his great AnyKernel implementation.

Just uploaded a small update after a long testing period. It's safe to say it's stable for use! I fixed a couple bugs, removed zram compression (not used, a waste of space), removed a little bit of bloat and set some settings to their proper values.

would be helpful if you state update date in the title of thread

Uploaded a very tiny update, only change is the default GPU governor is now simple_ondemand

Hey at least implement pdesireaudio correctly
Well I don't feel like publicly saying **** about other's work (since the kernel is really good, awesome job man) but if you really want pdesireaudio working maybe you should pm me
Again nice work man, good kernel

this is unbelievable a custom kernel for our device many thanks and huge respect God bless you brother. i have 1 request too please try to build Linux 4.9 kernel for this device too in future if you can (maybe it's too much to ask but it's only a request)

ram management is good due to inclusion of swap partition (1gb) and battery seems to be draining fast

Hi, i never used a Kernel before. I used lots of roms but I dont know what is kernel and why is it important. Anyways.
I was wanting to use KCAL app, it seems it's working with it. I have some questions.
1- how to back up my own kernel, so if I want to restore it I can go back to my original kernel.
2- is it just some kind of backend thing, if I install this it will not act like a rom and reset all the data on my phone right?
3- somebody says it have battery drain problem above in the comments. I don't care about battery drain so much but how it drains, like 1% per 2 or 3 minutes is okay but if it's less than this it won't be okay for me.
4- as I said above, I will use it for KCAL app, is there similar great things that I can do with custom kernel? I don't know much about it.
That's all. Sorry for my bad English.
Thanks

Network guru issue has been fixed in the stable release. Thanks for notifying
I don't care about benchmark scores. The intention is to give a satisfactory performance with good enough battery life with as low heating as possible. If you care about performance nameless is probably what you should opt for.

nameless imo is the worst,day to day smoothness is non-existent,tap an app and you have to wait a sec for it to open up,so I'm excited to test your kernal sir, I don't care about gaming performance if that's what you were talking about,so far lineage os kernal seems to be the king when it comes to responsiveness

thankyou for quick update bro! i can live without benchmark scores or performance!
I'm using it since tomorrow till now the experience is good enough! I'll update after spending sometime with it!

Going to try this one soon. But I've somy questions (noob ?). My Z2 is now on AOSiP-9 with Nameless r29 and L-Speed installed.
- Can I just flash this kernel directly? Or flash AOSiP-9 over again and then flash droopy?
- Do I need to uninstall L-Speed? Or is there any need of installing L-Speed, spectrum or similar app?
I don't need any performance based kernel since I don't play games. Only need a battery oriented one with enough speed for daily use, that's all. So definitely gonna try this very soon.

Dirty flash ROM, then flash kernel then magisk if necessary. Flashing on top of other kernels will likely give miserable results.
Using L-speed or any kinda mod with the kernel is not recommended. What works with other kernels probably won't work on droopy. I don't expect users to use any companion apps. It is supposed to give optimum results by default. If the default setup is not up to your expectations, use kernel managers like FK kernel manager[recommended] or kernel adiutor for tweaking the setup. There are more than enough tunables to play with. However do note, that I am responsible only to the default setup, and any mishaps due to changes from user's end is not upto me to solve.
