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.

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..

Heavily tweaked elementalx should satify your needs :)

Tapped from my ①+②=❸ ;)

    So I'm seeing worse battery life on stock/rooted rom than without Sandy. Loss of 10% overnight. I just booted Sandy without any changes. Any suggestions? Have seen some suggestions for changing display stuff and that's interesting, but main issue is battery life.

    The whole OPT experience is pretty mediocre so far for me:
    • Not a gamer so don't care so much about performance
    • Battery life v. disappointing
    • Agree with the washed-out-ness observations
    • Takes foreva to boot. (added)
    OTOH, the OPT camera experience is vastly better than on the OPO. The one thing so far keeping me from selling this thing for now.

    you can fix the washed out colors by using Kernel Adiutor on this Kernel.

    Reduce brightness value to 124, keep contrast at 128. This changes the gamma to 2.2 instead of 2.1. Increase saturations by 5. THis makes intermediary color saturations a bit more vivid.

    I have calibrated with spectroradiometer and those settings should provide good colors for everyone. In terms of color temperature you can make it more netral by reducing green by 6 and blue by 15.

    Don't forget to thank me. :)

    Anyone have a good screen color configuration? It looks washed out and bright compared to my OPO.

    Yes, see my post above.
