2nd post: How to add Spectrum support to your kernel
3rd post: Spectrum Injector

What:
Spectrum is a simple, profile oriented kernel manager that allows developers to create profiles to serve to their users. This is useful for users who are inexperienced with kernel tweaking or users who want something that's a single click away.

How:
Choose from Balance, Performance, Battery, or Gaming profiles to quickly and easily change kernel settings to your preference, now even easier with the included QuickTiles.

Features:

  • Dark Material Design theme
  • 4 Profiles to choose from: Balance, Performance, Battery, and Gaming
  • Nougat Quicktile support
  • Launch QuickTile
  • Profile selector QuickTile
  • Customizable kernel name string
  • Easy to add, yet versatile kernel support
  • some eastereggs but shhh

History:
I initially intended Spectrum to be a companion app/updater for my kernel, Electron. However, I decided to make the app open and available for any developer to integrate into their kernel so that more users can have a simple kernel experience.

Download:
Spectrum on Google Play
Spectrum is also open source, you can find it on GitHub.

Thanks:
I'd like to give a special thanks to @The Flash for being an early adopter of Spectrum with Flash Kernel, and the tons of support and testing he gave while Spectrum was in development. I'd also like to thank @xanaxdroid for all the testing, critiquing, and support throughout development. Also, a huge thanks to @franciscofranco for the inspiration and giving code improvement tips. Couldn't have done it without you guys.

How to add Spectrum support to your kernel:

Original documentation: GitHub

You'll need to add these 2 files to your devices ramdisk:
  • init.spectrum.rc
  • init.spectrum.sh
These files can be found on Github https://github.com/frap129/spectrum/tree/master/ramdisk

Now we have to include these ramdisk files. To do this, add
Code:
import /init.spectrum.rc
to the top of your devices main ramdisk file, usually called init.DEVICENAME.rc.

Next let's add your kernel name to the app. Open init.spectrum.rc and change "Electron" in
Code:
setprop persist.spectrum.kernel Electron
to your kernel's name.

Now just customize the 4 profiles in init.spectrum.rc to your liking! Profile 0 (Balanced) is the default, however, this can be changed in init.spectrum.sh. Here's my init.spectrum.rc file as an example:
Code:
# SPECTRUM KERNEL MANAGER
# Ramdisk file for profile based kernel management
# Implimentation inspired by Franco's fku profiles

# Initialization
on property:sys.boot_completed=1
   # Set default profile on first boot
   exec u:r:init:s0 root root -- /init.profiles.sh
   exec u:r:su:s0 root root -- /init.profiles.sh
   # Enable Spectrum support
   setprop spectrum.support 1

# Balance (default profile)
on property:persist.spectrum.profile=0

Recompile and your ready to go!

Some tips for profiles:
  • Make sure all profiles tweak the same parameters. Parameters don't get reset, when profile changes, so you have to make sure to change them back.
  • Not all profiles have to be complex! You could have one profile for your kernel and just use spectrum for minor tweaks

Spectrum injector

Spectrum Injector is a new method of adding spectrum support to your kernel! If the kernel you're running doesn't support Spectrum, you can add support without modifying it by flashing the spectrum injector zip. If the kernel does support Spectrum, flashing the zip will overwrite it and allow you to create your own profiles without decompiling the boot.img.

NOTE: These profiles are empty by default! You must customize them for them to do anything.

How to:
To create your profiles, you only need to modify the files located in /sdcard/Spectrum/profiles/ on your device.
These profiles are like ramdisk files, they accept commands of the format:
Code:
write /path/to/file value-to-set
along with all bash commands included in android such as
  • echo
  • chmod
  • chown
  • cp
  • mv
  • setprop

Once you have created your own custom profiles, you can apply them with the Spectrum app. Feel free to share your creations with other users, but remember, I'm not responsible for poorly written profiles that harm your device.

Testing spectrum, sadly I'm not able to add the quicktile. It disappears before I can drag it onto my active QT...

Wow @The Flash as faster at support than me for my own app. Guess thats how he got his name :p

Looks promising, but I'm awful at tuning kernel :p

Sent from my Redmi 3 using XDA Labs

One thing that helped me a lot was just learning what the tunables actually do: https://android.googlesource.com/ke...3.10/Documentation/cpu-freq/governors.txt#222

That documentation is a bit dense but can help a BUNCH when tweaking the governor. I'm always available to help with learning about tunables :)

Till now it's running amazingly for me. Great idle battery life and very smooth with the default settings. Great job!! :D

Why are you downloading them on mobile? Patching your ramdisk on your device?
Android Image Kitchen for Mobile Magisk version
by @Oms0sis

And yeah... No Linux machine at my house...

I've been hacking Franco's profiles into the kernels I use for a few weeks now... And this makes my life a little easier... I only have to edit one file... And import one script and I can run the 3 things I use on init...

I wonder if you could use the image kitchen to modify on device thru the app interface...

Oh... And I get a crash on startup with the app...http://cloud.tapatalk.com/s/590d20a022a97/Log_2017-05-05_21-01-26.txt

Thanks for the log! It looks like a rom issue as it doesnt report an error or reason that it stopped, but i could be wrong. I'll look into it

    How to add Spectrum support to your kernel:

    Original documentation: GitHub

    You'll need to add these 2 files to your devices ramdisk:
    • init.spectrum.rc
    • init.spectrum.sh
    These files can be found on Github https://github.com/frap129/spectrum/tree/master/ramdisk

    Now we have to include these ramdisk files. To do this, add
    Code:
    import /init.spectrum.rc
    to the top of your devices main ramdisk file, usually called init.DEVICENAME.rc.

    Next let's add your kernel name to the app. Open init.spectrum.rc and change "Electron" in
    Code:
    setprop persist.spectrum.kernel Electron
    to your kernel's name.

    Now just customize the 4 profiles in init.spectrum.rc to your liking! Profile 0 (Balanced) is the default, however, this can be changed in init.spectrum.sh. Here's my init.spectrum.rc file as an example:
    Code:
    # SPECTRUM KERNEL MANAGER
    # Ramdisk file for profile based kernel management
    # Implimentation inspired by Franco's fku profiles
    
    # Initialization

    Recompile and your ready to go!

    Some tips for profiles:
    • Make sure all profiles tweak the same parameters. Parameters don't get reset, when profile changes, so you have to make sure to change them back.
    • Not all profiles have to be complex! You could have one profile for your kernel and just use spectrum for minor tweaks

    Spectrum injector

    Spectrum Injector is a new method of adding spectrum support to your kernel! If the kernel you're running doesn't support Spectrum, you can add support without modifying it by flashing the spectrum injector zip. If the kernel does support Spectrum, flashing the zip will overwrite it and allow you to create your own profiles without decompiling the boot.img.

    NOTE: These profiles are empty by default! You must customize them for them to do anything.

    How to:
    To create your profiles, you only need to modify the files located in /sdcard/Spectrum/profiles/ on your device.
    These profiles are like ramdisk files, they accept commands of the format:
    Code:
    write /path/to/file value-to-set
    along with all bash commands included in android such as
    • echo
    • chmod
    • chown
    • cp
    • mv
    • setprop

    Once you have created your own custom profiles, you can apply them with the Spectrum app. Feel free to share your creations with other users, but remember, I'm not responsible for poorly written profiles that harm your device.

    Ah, of course! Thanks

    Wow @The Flash as faster at support than me for my own app. Guess thats how he got his name :p
