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.

-----------Edit-----------------
Testing out latest build for potential zzmoove governor fix with new hotplugs (Alucard, Mako, Bricked).

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

 

[davtse]

v1.02 still cant see zzmoove, and kernel version in about phone says unknown

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

 

[haikalizz]

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

 

[haikalizz]

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

Would it help if we could find some hotplug driver for another 615 snapdragon device?

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..

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...
