[KERNEL][P-S] riseKernel for A5|A7 2017

[Simon1511]

Dear folks, today I'm presenting my very own custom kernel for the Galaxy A5 and A7 2017!
This kernel provides many features and a lot of customization.

*To change settings, it's recommended to use HkTweaks by @corsicanu
because it is made especially for Exynos7880 devices. Other apps like kernel adiutor or Mtweaks
do work too, but they may miss some settings.[/CODE]

DISCLAIMER

*Im NOT responsible for bricked devices, dead SD cards or any damage done to your device.

Compatibility
This kernel is compatible to all variations of A5 2017 and A7 2017.
Only A520F is well tested as I have this device.

• Latest A720SKSU5CTL2 kernel release

• USB charging default changed to 900mA
• CPU and GPU voltage control
• DevFreq voltage control

Wow, nice, good job, will try it out!

 

[devil meru]

A520l will try tomorrow

 

[MattJaO3D]

Working Great with pixel experience ROM, I've upped the voltage on GPU and CPUs , Played COD mobile default all is good , used GLtools to get max graphics , and again all is good

 

[MitchiePitchie]

Just flashed it. Already encountered a bug, hk keeps on loading. Looking forward on your developments. Good luck
And unlocking the phone through fingerprint seems slower now for some reason. Opening apps is also slower now. Btw im using Google pixel Pie Plus

 

[SnowFuhrer]

Flashed it and working good so far. I think you're the first to make a custom AOSP kernel for this phone.
Magisk 20 is working for me, it just takes a few tries to boot sometimes.

Idk, it's all working good for me. Hk is working good too. I am on PE.

Unlocking the phone takes longer because the CPU clocks down on all cores when the screen is off. Therefore it needs longer to unlock. At least this is the explanation that makes the most sense.
That apps are opening slowly sometimes is also a bug I encountered, forgot to mention it in my OP thread. This can be fixed by simply reinstalling/updating the app or doing a clean flash (install ROM, then kernel right after)

Will do. Thanks

Cpu hotplug does not work for me

You mean hotplug in general or the governor called hotplug?

Hotplug in general

I'm laughing so hard thinking of this title as "Riiiiise and Shiiiine" Project
Good work btw

 

[SnowFuhrer]

With crDroid and this kernel, I got 106k in antutu. I love the fast charging too. Such an upgrade compared to "stock" aosp.

 

[moozer]

Latecomer... flashed and rebooted first time on Magisk 20 using crDroid

Going to have a play with some features and report back if I find anything useful.

Thanks Simon

97117 for me. Going to tinker then have another go. Best score I've ever had on this device though.

Replacing the device soon though

So far so good. Been trying some settings I had on my Xperia SP about 4 years ago and they seem to be working well for a balance of performance and battery.

Simply put:

CPU governor - Interactive (max and min frequencies set at maximum and minimum accordingly)
I/O scheduler - Fiops with Internal Storage read ahead set to 1024KB
I/O scheduler - bfq with External storage read ahead set to 1024KB

No CPU hotplug (really only useful for stock Sammy kernel)

That's it

Feel free to try and report back with your own findings.

I'm finding little lag now (was getting some really big lags and micro freezes) and battery draining slower

My results was with GPU overvoltaged and no apps other than hKtweaks, magisk and antutu. So hardly real world.
