No stock, as in ''for custom/AOSP only'' ? Would be great
Cheers and TIA
Great and thanks for kernel.
Im flashing it with twrp and not boot on rom(im with aosp of adrianom)it reboot only in twrp
Thanx beroid for your valuable efforts buddy!
and...Would this kernel be suitable for gaming in AOSP N, Coz TBH, AOSP and LinageOS Nougat both sucks when it comes to gaming!
The best was stock lollipop+Fishears kernel!
Flashed the kernel on latest Nougat AOSP build BUT ONLY REBOOTS IN RECOVERY!!!
In short, this kernel doesn't work with any ROM. No stock, no AOSP, no Lineage.... What is the purpose then ?
I'm on LineageOS 14.1, 20170623 nightly. kernel is working fine. device feels smoother and faster. have not tried gaming since I don't play anything on this tablet
Does it work on CRDROID?

Sent from my Nexus 6P using Tapatalk
Update - v1.02
added IOSched switcher
patches for several CVEs
fixed installation for LOS-based ROMs
just flashed on latest lineageos and suddenly my v500 is rebooting its ass off.
with this kernel, my tab needs a few minutes to somehow stabilize. like when I boot it up and use it immediately, it reboots. it has overheating issues which makes it reboot while gaming, ex. vainglory on low settings. this got worse in 1.02. I even have mako hotplug enabled and cpu temp limit enabled
Doesn't work on AOSP, only reboots in recovery....
Thanks man !!
Awesome work upstreaming the kernel and adding all those excellent features ... Worked flawlessly here on mokee N ... Would be great if you add zzmoove as governor ! Thanks man !
Update - v1.03
Updated toolchain
Patches for several CVEs

Nice Kernel!!!
Could you add Spectrum support in your Kernel?
Hi, I flashed the kernel in the new OneUI 2.0 Android 10 and it caused bootloop, I tried the other kernel and it didn't work too. My device is A600G with latest Android 10 build.
Edit: Sorry the problem is not the kernel I tried to flash only TWRP and got bootloop again.

I see. That's why u are trying different kernel. I just got back to android 9 because i can't stand the lag. Luckily they got the same Bootloader so downgrade is possible. Will not upgrade to Q unless the lag is fixed.
there is a new version, RC13 still works with Pie OneUI. Meanwhile 13.1 is only for Q OneUI
And RC14 oneui is only for android 10 right?
