If you want/don't want *feature name* just reply this msg with *feature name* and problems/ideas with it

Booted normal. I cleared KA stored settings.
Now:
CPU - No changing. Default in interactive.
Hotplug - No changing. Default in mako-hotplug. No other hotplugs.
-- Before the kernel becomes stable, I think there's no need to add more features. You could also do major work in SINAI-N4.
-- once booted into launch, KA show Max frequency 1240MHz, after a few minutes it restored to 1512MHz, normal. 4 cores actived.
--dt2w - worked.
-- Thermal - it's simple, I like it~
--IO scheduler - I changed it to noop. Others no changing.
--Anything else no changing.
--Camera OK, 1080P video recording OK.
Today I will keep monitoring the logcat file to PC.
Thanks for your great work! BTW, you did so fast.

You writes to me to not modify governors/scheds

And I didn't touched it, mako hotplug is default in Quanta, I merged only optimizations, sdcardfs and other

I don't touch hotplug driver because it may cause music lags.

I add zen and other schedulers

What governors do you want to see?

By now, no reboot. And I have to join a meeting now... Governors are not so much important to me. We can see how nice the kernel will be.

 

[dcshallot]

I think the wakelock can be optimized.

I personally would like to bfq added, if it hadn't already.
And what is the current battery life on Quanta-Reborn?

About battery, you can see my screenshot upstairs.

 

[dcshallot]

A first random reboot, but it's still more stable than the other kernel.
I was in charging and playing coc.

Charging and playing may cause overhead

 

[sudokamikaze]

With this kernel you may use a Kernel Adiutor from GooglePlay

It looks fine, however what is your average SOT?
Mine will probably be slightly longer, as I do not utilize Google's Play Services, nor do I play games (and I limit the CPU's frequency, so it does not overheat).

Sot?

 

[dcshallot]

Everything installed. No self reboot.
Now I want to come back lineage OS........

Screen on time check it by going to settings battery then click screen it will tell you how long your screen has been on since last full charge

Quantum kernel or quanta reborn both are fine by me

I'm still connecting the cable. I'll upload a series of screenshot after a few hours.

 

[dcshallot]

Reboot.
I received an SMS message.
Double tap to wake.
Drag on lock screen to preview the message.
I was going to slice away the message, and it rebooted.

After the random reboot, it lost a few hours' record.

I just flashed LOS... But, it can't boot into launcher. Keep loading the booting animation. Sometimes I just consider maybe I should not use f2fs.
UPDATE: I converted /data and /cache back to ext4. Succed to boot into launcher. Hope it work well as old quanta.

 

[dcshallot]

In LOS, please disable default mako-hotplug. I see mpdecision enabled by default. If mako-hotplug disabled by default, ignore my question.
UPDATE: When I was restoring apps+datas, it rebooted, I thought it cause by double-hotplug. No logs, because I'm still reboot to applying settings.
LOS: 1080P video recording normal.
