[Q]kernel and overclock setting

What are the best settings to save battery and keep performance ? or What is the best settings to get best performence ?
and what kernels do you suggest ?

I use latest Andromadusmod kernel with cpu config: SmartassH3 & row (or smartassV2 & sio) battery is nice and performance is good

what would you suggest for a sense 4 rom ?

To sense 4 use this kernel: http://forum.xda-developers.com/showthread.php?t=1845039
Configure governor SmartassV2 and sheduler sio. Cpu speeds 1024 or 1200 are ok.
If I helped, click Thanks :good: :laugh:

Sorry but smartassv2 is not present in any of the kernels available there. On-demand is still ok though

Does this work with miui? Or only cm ROMs?

Working well on cm12.1. Fixed my WiFi issues with custom kernels as well. I don't see zzmoove amongst the govs, was it removed?

Thanks for the info, will look into it today. @Annasarp this only works on CM12.1, will try to look into support for miui.

I am on ver. 1.0 , not getting option to set hotplug .I tried kernel aiudtor ,trickster mod and set CPU.

same here but on first boot zzmoove shows, the next boot it disappears.. may need to disable it. On other news, new hotplugs Alucard, Mako and Bricked have been implemented. Will include in next update with some thermal and cpu freq tweaks...

Great! I come from the i9505 so I'm familiar with Alucard. Anyway just a question. My Big cores seem to come online more often then the little cores do, even when just doing UI stuff. Is this how the 615 behaves normally? I'm using alucard for both sets of CPUs and autosmp.

I think it's how the governor handles it... The big cores aren't always online using the settings provided, most of the time the little cores handles most of the UI, Games and stuff. I will try using alucard and see.

seems like autosmp hotplug is the issue. I turn it off, all cores stay online, the big cores stay at 200mhz while the small ones are used more actively unless load is heavier then all are turned on. under no load they're all at 200mhz but none of them go off

New build up, changelog and download links are in #3 post. Also @davtse have been using Alucard governor with AutoSMP, Big cores are usually online. May need to find more info about that, though this is a WIP...

After testing over the course of last night, i've found that most of the hotplugs have the same issue, but Mako just doesn't work at all. I think the problem is that none of the hotplugs are meant for octacore big.small cpus. If you look in alucard's folder in /sys/kernel/alucard, it only has variables up to core 3, 4-7 are missing

Testing new kernel with doubletap2wake and sweep2wake implemented in kernel... About the hotplugs, I may need more time on that.
------- Edit --------
Doubletap2wake and Sweep2Wake/Sweep2Sleep implemented in kernel but not working fully... Either it needs to be implemented in touchscreen drivers or rom... @k2wl

I tried Thunderplug from Yu Yureka, designed for Octa-core devices... Won't boot... Bootanim won't show, after MI logo is blank. Right now browsing through Yureka's forum to find other hotplugs..

Thanks for ur hardwork mate !
Can anyone tell me why when i set a recommended settings then always my big cores change the yanactive governor to interactive, just little cores stayin with yanactive, and please help me in setting up this kernel for the best gaming performance, greetings!

Could the settings, is your system set in performance or battery saving mod? Because that could overwrite the settings... Other factors could be like what @davtse said...
Also I'm still uploading a new version with updated files like thermal and cpu freq... Updated governors and dt2w/s2w are also included. For those who needs the source, sorry though, can't push to github with mobile data...

great work! thanks... by the way.. can you make kernel for kitkat 4.4.2

still at 4.4.2 F350S
any common kk or lollipop which one better?

xenus, i install your new rom with this new kernel, it very lag after flash but still can be load to os.

yes i install version 1.2 on d838
.its so lag even if its 2.7 mghz.change all settings but still lag is there..kernel not optimized
ty

Kernel updated to V0.1.3. Possible problem with sdcards is in device config - im use b1w(d838) config to build kernel.
On my phone (D838) all working fine.

whats the best scheduler for intelliactive? ty

Installed 0.1.3, testing now. I think it's faster than 0.1.2. I will charge battery to 100% and test battery life, but i think battery life is better on stock kernel. Which is the best combination of governor/hotplug/IO scheduler?

@xenius9
I think GPU overclock is fake, I set it to 650mhz but after some time it drops to 450.
Did you stoped working on new kernels?
