F.A.Q

Can I flash this kernel on Note 4 SM-N910C or other variant?

No, you can not. This kernel is only for SM-N910F, SM-N910G, SM-N910T and SM-N910W8.

When I switch to Ondemand governor I noticed that cpu-boost is disabled.

Exactly, Ondemand and cpu-boost doesn't work well together. When you switch to Ondemand governor cpu-boost will be disabled automatically. Don't re-enable cpu-boost if you are using Ondemand governor. (Synapse>CPU DRIVERS)

Which app can control this kernel?

By default, the kernel is controlled by Synapse, but you can use the app that you like (Trickster Mod, Kernel Tweaker, etc.).

I flashed the kernel and Synapse says: "No support UCI detected".

Reflash the kernel, since it was a bad installation and Synapse does not detect the scripts.

After flashing the kernel lost root what to do?

In case you loose root just flash SuperSU

Any recommended settings to follow using Synapse?

At the beginning of the second post.

After flash the kernel some apks give me FC.

Go to Google Play Store and reinstall those apks.

From where can I remove int.d script?

Go to /system/etc/init.d using any root based file manager and delete.

Note: There is an important one related to superSU and if you remove it by mistake you're gonna have trouble with root permissions.

My device doesn't show any reaction to undervolting (battery life is same as before) or gets unstable even on light undervolting?

Use DVFS disabler Module(standalone) (dynamic voltage and frequency scaling), this feature was kept in touchwiz for benchmark boosting purposes and will conflict with any undervolting and custom governors because it scales the voltages and frequency on regular intervals and is framework integrated, so gets a higher priority than kernel based voltage and scaling controls.

For people who don't know what is DVFS please refer Wikipedia.

Min/Max frequency don't stick?

If your frequency settings don’t stick, it's because on certain Qualcomm devices, there are certain system services (thermald/mpdecision/project butter) or kernel service that rewrite frequency settings based on current thermal status and/or touch input.

I made a logcat but my file is empty. How I can "fix" it?

By default Android logger is disable. Go to Synapse > MISCELLANEOUS and enable Logger Mode.

What is it PowerSuspend?

This new powersuspend PM kernel driver is a replacement for it and existing early_suspend drivers. It should give better battery life.

What is it Intelli-Plug?

Intelliplug is a replacement for mp decision. Intelli-Plug is Faux123 open source solution to Qualcomm's closed source mpdecision. Intelli-Plug is disable by default. It conflicts with mpdecsion, so is HIGHLY recommend turning off mpdecision when using intelli-plug! (If you use Synapse the change is automatic. If you enable Intelli-plug mpdecision will turn off).

What is it Intelli-Thermal?

an intelligent MSM thermal throttling kernel driver designed to replace the

closed sourced thermald(aemon) from Qualcomm.

What is it Frandom?

Frandom is a kernel random number generator, which is 10-50 times faster than what you get from /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.

What is it CRC?

CRC is a mechanism aiming to prevent data corruption when is enabled (reduce the performance around 30%). So if you disable it improve the performance but your data can be corrupted. Use it at your risk.
