Kernel Downloader

This is a feature which allows the user to download different custom kernels for their device. To add more kernel the developers have to add support by their own. I wrote up a documentation which explains how to do this.

Emulate init.d

Have an option to emulate init.d for ROMs that don't support it.

Path: /system/etc/init.d

Most ROMs don't support this, but androguide.fr has an app that emulates init.d for all ROMs with root/busybox. If you need more info, I'll try my best to provide some details, though truthfully my knowledge on this is rather lacking.

Here's the link to his project if you need some sort of reference: https://github.com/Androguide/Universal-init.d/tree/master/src/com/androguide/universal/init/d

dark theme

Could you please add a dark ui - if time permits (functionality over look). Thanx.

Revert to Default

Have the users be able to revert all settings (or a specific setting) to a default value.

enable/disable smb135x wakelock on N6

Can you add this N6 tunable mate?
It's related to power (maybe put on misc tab?)

"enable/disable smb135x wakelock"

Nexus 6 tunables

Hope you can merge some nice tunables for N6, some work also for N5

Tap2Wake

/sys/devices/f9966000.i2c/i2c-1/1-004a/tsp (string "AUTO" or "OFF)

Vibration intensity N6

/proc/sys/vm/laptop_mode (true/false as 1/0)

Color profiles

please add it :D

Android logger on/off

Toggle for Android logger on/off

/sys/module/logger/parameters/enabled (1 enable or 0 disable)

SELinux Adjustment

Would be nice to see this app have an option to set SE to Permissive or Enforcing.

To set kernel to Permissive through terminal: setenforce 0

Some mods like V4A require the kernel's security to be set to Permissive. There's already a Google Play app that adjusts SE and applies it on boot, but I would prefer my system tools to be in one app.

Fast Charge

Would love the fast charge functionality.
Code for terminal:echo 1> /sys/kernel/fast_charge/force_fast charge

Kernel permissions

It would be a good idea to set necessary permissions to all the tunable files, my device LG F6 for example can't change the governor because the permissions are set to 444 and not what they're supposed to be in which I set them to 777.

Need delay settings

Some kernels apply their settings after sometime. The should allow for delay so that settings from kernel are overrides by the app. Eg Uber kernel uses 30 seconds time before settings are applied. Due to this my settings from this app never gets applied.

Nexus 5 GPU governor

/sys/class/kgsl/kgsl-3d0/pwrscale/trustzone/governor (string)

Add option to change language

Since some languages aren't fully supported or badly translated, it would be nice to have the option to change languages.

msm_hotplug controls

Hi there, is it possible to add msm_hotplug, the path is as below

/sys/module/msm_hotplug

Thanks Sir,

Thermal throttling option

Add the CPU thermal threshold value option.

My bricked hotplug

/sys/kernel/bricked_hotplug/conf

All files are the same as the normal bricked_hotplug ones

Scaling of the usage card on smaller devices

Larger phones it looks normal, but on smaller phones like the s3 it looks bad this commit should fix it
https://github.com/deadman96385/android_packages_apps_KernelAuditor/commit/eb2e89c25fadf3c35ab6849d341baae76f588bce

Add a indicator to the Widget

Just a small enhancement, it would be cool to see on which profile i'm on the moment, maybe via a small dot in the widget, or just make the active profile bold

Nexus 6 wakelock tunables

I think I made mistake on the wakelocks.
Now the proper:

"smb135x wakelock" prevent wakelock when power disconnected
/sys/module/smb135x_charger/parameters/use_wlock

"sensor_ind wakelock" prevent wakelock when Ambient Display disabled
/sys/module/wakeup/parameters/enable_si_ws

(Y wakelock on or N wakelock offf)

Widget

When i apply a profile which is already set via the widget the app chrashes and I can't use the widget until I reopen the app.

DT2W Feature

Dear reader,

First of all: very very nice design!

A very nice and handy feature for the Nexus 5 dt2w feature would be to have a timeout option for it. The dt2w feature consumes more than 1% per hour on our device, so it is quite unusable right now. It would be awesome if you could implement it! You can always contact me under till22 on XDA.

Cheers,
Till

TI OMAP Color calibration

Please add support for TI OMAPDSS color colibration. Many devices based on OMAP 4430 (including Moto DROID RAZR xt912) have annoying yellow tint. There are no software that support color calibration for OMAP. It would be great if you will help.

Widget for Profile switching!

Hi, first oft all awesome app!!!

I just found it today and till now all functions work great. Really really amazing, best CPU/kernel control app i tried and design is nice too! 10/10

However there is one feature im missing! The ability to set CPU frequency and governor (and multi core Option not to forget) make this an almost ideal battery saving app. Being able to save all settings in profiles, i made a performance and an energy saving profile.
Now it would be really awesome if i could quickly switch between the profiles! A simple widget would do the job. Having this in quick toggles would probably be even nicer, so you could acess it without returning to home screen, but i guess this would be more work to programm.

Thanks for sharing your awesome work!
-generalcool

current CPU temperature

Like in battery you've battery temp and voltage etc etc
Would be great to have current CPU temp in CPU options

Battery profiles

Also a widget to change profile quickly.

KCAL - Advanced color control color profiles

Can you add color profile loading for the new KCAL driver?

The text files format is 2 lines (first is colors, second is controls):
kcal
kcal_sat kcal_val kcal_cont kcal_hue

You can add a default button to set the default profile:
256 256 256
30 127 127 0

Mako Hotplug Controls

Can you add control for mako hotplug from franco? I will give the paths if needed, I just need to look into it a bit more on my side, I will add them here if required once I find them.

Thanks in advance, you are doing an amazing job:)

wake controls nexus 5

"set DT2W"
/sys/android_touch/doubletap2wake (0 disabled, 1 enabled halfscreen, 2 enabled fullscreen)

"Set wake timeout"
/sys/android_touch/wake_timeout (int timer in minutes, 0 is disabled)

"Use power key suspend override"
/sys/module/qpnp_power_on/parameters/pwrkey_suspend (0 disabled, 1 enabled)

Sound Profiles

May have the option of "sound profiles" compatible with various kernel ... eg faux, hybrid and other ... would be great if it had

Nexus 5 LCD dimmer controls

"Set backlight dimmmer"
/sys/module/lm3630_bl/parameters/backlight_dimmer (Y enable, N disabled)

"Dimmer level"
/sys/module/lm3630_bl/parameters/min_brightness (int 1~10)

Nexus 6 msm_hsic_host wakelock

"msm_hsic_host wakelock" prevent msm_hsic_host wakelock
/sys/module/wakeup/parameters/enable_msm_hsic_ws (Y wakelock on or N wakelock off)

CFS Scheduler Policy (Multicore Power Saving)

The possible values are in a string in:
/sys/devices/system/cpu/sched_balance_policy/available_sched_balance_policy (normally performance and powersaving)

The set value is a string in:
/sys/devices/system/cpu/sched_balance_policy/current_sched_balance_policy

Check info: https://github.com/engstk/shamu-5.0/blob/f48e3201760cb8464b435a5cf916e97cd3a188d2/Documentation/ABI/testing/sysfs-devices-system-cpu

descriptons

First I wanna thank you for this cool app. And the second, I think ther should be descriptions (manuals) for parameters. Texts can be taken from other apps, for example Devil Kernel Manager.

enable/disable faux sound control on N6

Mate can you add this tunable to faux sound?

"enable/disable faux sound control"
/sys/module/snd_soc_wcd9320/parameters/enable_fs (Y or N)

Add Photo References in the Screen tab

It would be nice to have some sort of photo reference (like a picture of a parrot or an apple) when changing colors or calibrating the displace.

For paths, I guess you can have a look at these examples in the links ;-)

C State control

I believe the c states control would be a good option, sorry I don't currently know the sysfs portion for these, they are found in the faux kernel manager application.

Implement Devil Kernel Manager functionality

Language Option

Can you put a settings sections and add an option to choose app language. I know that there are translations but there are some terms, that don't always make sense when translated. So I would prefer if it was in English, because I understand the terminology in English.

Checkboxes indicating cores status should be disabled to and skinned to show user that they are not controls
