Yes updated OP last time with a newer download link:
Fixes Wi-Fi randomly disconnecting issue
Tested with 3dmark, 2000+ increase in score, >10% fps increase with gaming
Maybe just my end as i have xposed framework & gravity box, but auto rotate doesn't work so well, stays fixed on initial orientation.

OP Updated, fixed sensors that everything working now
also restored CPU touchboost as it uses low power core and it makes it smoother compared to without it.
Confirmed as working. Definitely running cooler as well now.

For android 4.4 but it should work with 4.3 (untested)
Loving the latest Kernel mate, nice work.
I can quite agree with Nvidia making modding this tablet hardwork with their sources being like they are.
Whats even better with this Kernel is we can now have Custom bootanimations without it hitting the dam /lbh partition for it. So now i have a Android L Bootanimation lol

Set CPU is good, haven't tested antutu master etc etc, setting one core will set all cores so all applications should be compatible

Well I've tried both trickster mod and antutu and whenever I set the cpu speed and governer, press apply, then exit the app when I open the app again it reverts to the original CPU speed and governer that the kernal came with. Any fix for this ?

I haven't not had that issue, if you can provide a log maybe I can look into it. Make sure you have root, I have left userspace control so everyone can still control it within the setting menu choosing Max power or power saving. Oh I have 2 incoming updates tonight

Update
All the changes I made were merged into CoCore-refresh kernel (3.0.31) and 3.0.101 by TeamCanjica, so they will hit 'mainstream' in some time when they release another build.
This thread is over
/Update
Hi,
I've been working on this kernel for some time with improving undervolting in mind. It's based on CoCore Refresh r10 by CoCafe and of course the credit goes to him where it's due.
Main changes:
- rewritten liveOPP internals.
It improved stability a lot - it now allows to use 300/500/700/900 MHz frequencies with no problem and it allows to undervolt low frequencies even more. Freqs >1GHz are now stable at varm=0x32 (at least on my phone), which also saves a lot of power.
Freqs <=400 MHz now use 0x12 (0.925V) voltage by default - It's the original voltage for 400MHz and you can go even lower when undervolting
- rewritten Mali booster algorithm.
It's far from perfect yet, but it eliminated instability due to the fact, that CoCafe's mali booster and "original" booster (switching between APE 50/100 OPP) were working independently and could cause a crash when the original algorithm switched to APE_50_OPP while mali boost was active. APE_50_OPP voltage is 1V by default (0x18), so when clock is boosted to i.e. 700MHz and it switched to 50 OPP, the result was 350MHz @ 1V, which mihgt be too low.
- allow to set APE and DDR OPP with liveOPP
echo apeopp=25/50/100 > arm_stepXX and echo ddropp=...
before the kernel would set ape/ddr opp to 100 for freqs above 400MHz
- allow changing ape_50_opp voltage
echo 0xXX > /sys/kernel/mali/mali_gpu_vape_50_opp
- make wlan/mmc boost tunables available through sysfs in /sys/kernel/performance/*
- Memory split changed to 2G/2G and switch highmem off - it's not needed with this split
- removed some unnecessary drivers and moved others to modules to reduce kernel size
- changed kernel compression to LZO
- 631MB available memory
- 7800ms kernel boot time
Download & install:
Mediafire
That's partition image - flash it with dd:
Code:
dd if=kernel.mk-r1-release.img of=/dev/block/mmcblk0p15
It's also good to create a symlink from /system/lib/modules to /lib/modules - it'll allow modules to autoload, enable modprobe to work and also you can use KoControl app to manage module loading.
Source:
GitHub
TODO:
- create a package for flashing with recovery and place modules (7MB) in /system/lib/modules instead of a ramdisk
- touchbooster has a bug that causes it to limit max freq to 1000MHz on boost.
- figure out how to enable setting of minimal cpu freq - now touchboost always resets it to 100MHz
- add interactive gov from Zwliew kernel
- create more power optimized, auto tuning 'foreground' governor (long story)
My voltage settings
(default kernel voltages are more conservative - set those from init scripts and test them for stability!):
100 - 0x0f
200 - 0x10
300 - 0x11
400 - 0x12
500 - 0x14
600 - 0x18
700 - 0x1d
800 - 0x24
900 - 0x28
1000 - 0x2f
1050..1250 - 0x32
Mali gpu voltage
Default voltage from CoCafe is way too high - idx0 vape could be just 1V since that's the voltage, when mali is running at 1/2 speed (200MHz by default).
My settings (for safety they are 3 steps higher than the lowest working voltage for given freq).
#0 - 0x17
#5 - 0x1c
#9 - 0x23
I don't overclock the gpu - my low index is set to 0 (200MHz), and hi (boosted) to 5(400MHz), which is the original mali freq. That gives mi 100MHz when working at half speed. I don't use any fancy UI effects, so it's enough - when not plaing a game, mali is only working at 100/200MHz and only boosts when loaded. Params:
boost_low idx=0
boost_low threshold=30
boost_delay 2000
boost_high idx=5
boost_high threshold=220
Default kernel settings are left unchanged - set those manually from init scripts.
I place the thread here because I'm not allowed to post in developer forums (<10 messages limit).

Wow. Thanks for your work, mate!
Most people are using CM or CM/AOSP based ROMs nowadays, but there are only a few people (like me) who still use Jellybean. So, I'll try your kernel very soon and I'll post a review after using it.
You joined XDA on 2010 and yet, this is your first post. That just doesn't feel right.. Anyways, keep up the good work, mate. :good:
Good to see another kernel developer for our phone! I'm on stock rom now, I will try it out

The code is on github and there's no problem with merging it with some cm kernel. When I'll try my with some 4.4 again (so far each one had something broken and didn't suit me), I'll probably do it

To keep it short let just say that I'm not a sociable type of guy... but when I have something of value, I try to share...
One more thing (most probably know it, but for those who don't) - 99% of "user experience" depends on the settings of governor, mali and touch booster - if you screw this up, no kernel will work smoothly. I had this problem with my first vanilla jb - it sucked as hell(ondemand), but when I set sampling_down_factor to 3-4 suddenly it was very smooth. Default gov params aren't always the best. Thats one of the reasons I'll try to write a governor that tunes itself and adjusts itself to the app currently in foreground - but that's just an idea and it'll take me some time to refresh all the math needed for it...
Anyway - enjoy the kernel.
Hmm I really wanna test this kernel, but I'm currently on Vanir
I definitely gonna follow your thread, it's good to know Janice is still alive and kicking

You can always ask rom's devs to merge my changes - it's just a few commits.
And how is that rom working for you? At the time I was checking up 4.4 roms each one of them sucked in a different way. Carbon was the closest (in fact it was the only one acceptable) to being useful (feature- and ui-wise), but it had some process spinning in the background and It was draining my batt (it was unkillable because it was a part of lock screen I think - the bug was known, but no fix available at that time).
If it's similar to carbon I might give it a try...

Well I use to be a Carbon die-hard fan before, but since the dev have got himself another device, so I just had to change rom.
And then I try Vanir. Surprisingly it's pretty stable, and we have official support by the Vanir team too.
Feature-wise its just as good as Carbon, but I kinda miss the pie, since Vanir doesn't have it.
And I think Vanir have a bit more features than Carbon do.
Anyway can you go lower than those cpu voltage on your OP? Or is it really not stable?
Mine's 1000 is at 0x2c, 800 at 0x20, and that's the lowest I can go.
And thanks for the gpu voltage :good: , I actually use that value now :laugh:

Actually I didn't recheck those two and focused on lower freqs - these were the limits with older LiveOPP, but now I can go to 0x22 and 0x2c.
In fact, 0x24 and 0x2f are already undervolted values - original are 0x28 and 0x32. But every bit counts, especially on higher freqs.
Thanks for the tip
But what's more interesting - 900MHz works at 0x23 (didn't test that before - just took a voltage halfway between 800 and 1000)... there's something wrong with this ARM_100_OPP, but I don't know what yet... Will test the rest again later and post my results.

If you don't get random reboots/crashes than it is - when following my guide, the resulting voltage should be stable, but it isn't always so... I'ts just a starting point that can save you some initial crashes or the other way around - if it doesn't pass freq_jump test, then it isn't stable for sure

Only those two - three actually - also 200MHz (that is low_boost/2), but with ape_50_opp voltage, not the one from dvfs_config. There's not much point in doing any smarter gov because gpu intensive apps usually load it at 100% no matter how much power it has - they just have more fps then.

I'm trying to build Carbon rom for out phone since last night... when/if I'm done, I'll patch the kernel with my stuff and push it somewhere. What is your kernel version? I think that both carbon and vanir use the same, or at least similar one.

Not really I't an old BMW F650 - only 48 ponies (of which some might have already died of old age ;P). But in reality you can do most of the fun stuff with as little as 125cc Anything bigger is usefull for longer trips/highways/trips with passenger/etc... I mostly ride small country roads and light offroad, so I rarely go over 100km/h, so no badass machine is needed something like 350cc would be best I think. Actually - it's not the bike you ride, but how you ride it... and on narrow roads with many turns a bigger bike is event sometimes harder to ride...

It is simple, tested on my nexus 6, just go to system/bin and delete mpdecision, then install an app that controls kernel, like kernel adiutor, raise min freq of cpu to 883000 mhz, then set apply on boot, reboot phone and enjoy lagfree and smooth super battery life

Disabling in a kernel app will accomplish the same thing. The reason you are seeing a change in battery life is because of the 3 second input boost of MPD. Most of the custom kernels have a generic touch boost driver that is set to 1 second or less to take the place of the mpd boost and increase battery because of the decreased boost time.
MPD works great for some people and not for others. It is greatly dependent on your usage habits. For my typical usage, with mpd on, I average 6-7 hours of screen on time. If you are a gamer, where you are constantly touching the screen, mpd will adversely affect your battery life because of the constant boost.
As a kernel developer, I definitely would not recommend deleting the mpd binary. I would suggest trying a couple of different kernels and/or configurations to accomplish the same results.
lol.. seriously? i guess thats one reason that ive disabled mpdecision for the last 3+ years on whichever nexus i was on, but not the main reason
How can I turn mpd off on ex kernel manager
you don't need a kernel app to disable it BTW. all kernel apps do is provide a ui for you to use. it can be done via a terminal emulator app.. type,
su(press enter)
stop mpdecision(press enter)
and that's it.
I'm using kernel auditor and in the CPU hotplug section the first listing is mp decision. Is that what needs to be disabled?
OK, silly question.. do you know what mpdecision does? do you know what disabling mpdecision does?

@simms22 good point here. This is good for everyone to know. If you disable mpd without a replacement, you risk all cores not coming back online after deep sleep. Mpd doesn't actually control hotplugging, it controls input boost and onlining of cores.

and that's exactly why I disable mpdecision, so I can have all 4 cores active at all times.

When you say without a replacement what are you referring to? Trying to learn here..

A replacement such as Zen, Mako, Blu_Plug, etc.
Also, (just an FIY) Zen isn't really a hotplug (it keeps all four cores active at all times, unlike Mako, Blu_Plug, etc). It's still lumped in there for some reason.
I highly recommend disabling MPDecision. You know what MPDecision stands for, right? MakePoor Decisions

I'm running elemental x now and I can't find mp decision on kernel auditor. Do you know if it is included with this kernel? If so how would I disable it?

i believe its already disabled in elementalx kernel. anyways, you can always use a terminal emulator app, then type..
su(press enter)
stop mpdecision(press enter)
thats all. all kernel apps do is give you a ui to whats already available.

Some kernels come with it already removed. Check the features section of the original post in the Elemental X thread or try searching the thread.
I can say from experience that Kernel Auditor doesn't give you access to all of the adjustments in Elemental X. Some features are only accessible through the official Elemental X app, so it might be there, but you can't use Kernel Auditor to adjust it.

If I'm not wrong, these profiles are for the 3 (820). Have you made any changes to the values to make it work perfectly with the T?

Those profiles are for the OP3.
The OP3T is not supported,yet!
Any screenshots with battery stats?
I'm trying it. Flashed the file 2 hours ago and no errors, bootloops, crashes, force closing app etc. for now. Will report battery stats tomorrow because I have to fully charge my phone first. Just to mention : AFK (that for now is only for op3) is coming soon for op3t too

Please someone revert back if they are getting insane battery life as shown in video. I'm unsure to flash it as of now.

Hi I'm highly satisfied with my oneplus 5 and I like to show off my benchmark scores. Recently my benchmark has only been around a little over 150k when I use to score 185k sometimes 190k. Anyone know why this is? I do have xposed framework installed but I even switched my Rom and tested it and still got only 155k. I don't notice any drops in performance I would just like to know what the issue may be. Thanks guys
182k on No Limits 3.4 rom with Franco kernel v7.

Hey,
Your processor scores significantly less than it should, usually it scores around 40000 on the oneplus 5.
Maybe it's underclocked?
Please upload a screenshot with more details, like this one:
Best regards,
Most probably the highest frequency of big.little is stuck at an lower frequency. Go to developer options in ROM and turn on overscale CPU usage, then run Antutu again and see what's the highest frequency(s) you got while running. If it doesnt go above 2457mhz (cluster 2) than it makes sense why your score is low. Also check your "i/o" scheduler and "read ahead buffer size" in your kernel tweak app. This can also affect your score.
Besides all this, don't run Antutu with low battery this affects the score for sure.

Thanks for the help I'm going to reflash my rom and see if it helps.
Benchmarks are what they are... Anyway I've tested with stock kernel and it's giving even more:

reflash, keep it clean, full charge, put it in the freezer pluged-in. andddd hit 188000 :good:
I wouldn't get too caught up in the whole benchmarks thing. They don't always translate to real world performance; I would rather show off my phone's snappy interface (i.e. quick app loading, navigating menus, etc.)
I personally think that's worth showing off more than just numbers that appear on an app!
Just my two cents though, you're free to disagree and do what makes you happy of course

Yea I don't notice any less performance so I'm not too worried about it. I do wonder how my big cluster got set to 1.9 ghz tho as I haven't messed with the tuning of my kernel seems to try to set it as default. But like I said I have xposed, a couple of audio mods, and gravity box. I'm bound to have some unwanted side effects from it.

Fair points! Kind of off-topic but I'm just curious as to how you went about installing Xposed? Are you using the Magisk module or did you flash via TWRP?

It is an option to flash with xXx Rom but Ive flash the purify xposed zip via TWRP. I've also used the systemless xposed from magisk but I believe it only works if you already have xposed installed.
