Can you please udate this kernel???
[Galaxy S 4 i9505 Original Android Development] wonderkid802:
I don't think this kernel works on c-rom, has anyone used it on that rom?
[Galaxy S 4 i9505 Original Android Development] lup3x:
Will it work with omnirom on android 4.4?

Efficientdemand too effcient?

Good day.

I've discovered this kernel today and got excited because i've tried some combination of rom/kernel, even JB 4.2.2 so the battery could hold like my S3 did. And this was the only kernel that got it achieved. :good:

10 minutes later came the disapointment, cause when using efficientdemand governor, once the phone turns off the screen, won't turn on again until i reboot. Tried slimkat, carbon and liquidsmooth roms and happen all the same. When i use intellidemand the phone wakes.

Anyone happened the same?

Thanks.
[Galaxy S 4 i9505 Original Android Development] Hansoliv:
Please ignore my previous post, seems efficientdemand with multicore powersave set to 2 and 'CPU sleeper' program are incompatible. After setting multicore powersave set to 1, works well and has nice battery too.

Thanks

Hi guys,

this night i upload the 1.1.0 version with some fix :D i fixed the problem when the screen is off with audio (tested and works).

Thanks :)

Many thx teksin,

Gonna flash right away, 1.0.0 running great so far :thumbup:

Nice. I'm going to try this kernel for a week to see if this will help with the weird sound issues I had with KT.

Thank you for your time and work.

I have a problem that default GPU frequency can't be set. No matter which frequency I choose, default is always 320.
[Galaxy S 4 i9505 Original Android Development] Vladivid:
1.1.0 simply fantasy! I leave this kernel in daily use. Separate gratitude for sound correction. Thanks, teksin!
[Galaxy S 4 i9505 Original Android Development] teksin:
Can you precise the problem please ? i don't have it...

I'd be really great full if someone could please mirror the latest setting somewhere other than mega :) please!
[Galaxy S 4 i9505 Original Android Development] !crazy:
Well default frequency, the one kept by GPU when it is mostly idle is 320 MHz. In KTweaker there is an option under Extras to change that frequency to something else, like 200, 128, or whatever. When I set this with KT kernel it works, but with efficient kernel it is always 320.

[MENTION=1110418]teksin[/MENTION],

Just flashed 1.1.0 on the new AOSB - ProBam 1.2.9 from codekx.

After Flashing the kernel the ROM boots but freezes completely at startup screen. Need to hard reboot by holding power button.

Flashed 1.0.0 and everything is fine, could you pls check ? as I like your kernel very much.

Many thx.
[Galaxy S 4 i9505 Original Android Development] teksin:
That's strange ... do you have tried to clear dalvik cache and partition cache? i will take a look !
[Galaxy S 4 i9505 Original Android Development] Lucius1972:
Hi teksin,

Yes i did, flashed kernel then wiped dalvic and cache. As said same procedure with 1.0.0 and everything is fine.

Running 1.0.0 now till issue fixed.

Thx again buddy.
[Galaxy S 4 i9505 Original Android Development] fedef12evo:
i had similar problem with another kernel, and the problem was the powersaving battery option, in battery, try to disable it and see if works
[Galaxy S 4 i9505 Original Android Development] asbanoglou:
Mate i am running the excact same ROM 1.2.9 version with the same kernel 1.1.0 version and all works perfectly,you have done something wrong to be honest.
[Galaxy S 4 i9505 Original Android Development] Lucius1972:
This is already disabled, thought about that also. Thx

Hmm strange, I dirty flashed 1.2.9 over 1.2.8. (Just wiped dalvic and cache). Maybe I should try a clean install.
[Galaxy S 4 i9505 Original Android Development] asbanoglou:
I dirty flashed too mate and wiped dalvik that's all.Also i use the 1.1.0 version of the kernel not the 1.1.0S one.
[Galaxy S 4 i9505 Original Android Development] Lucius1972:
Ok guys, teksin,

All running fine now.

Just flashed 1.1.0 again and wiped dalvic and cache.

Strange what caused this, additional research saved teksin :D:thumbup:

Guys watch out! This kernel is not compatible with OmniRom! You will loose your baseband and IMEI, i don´t think i have to explain what that means. I don´t think it´s kernel´s fault (because ktoonez also has graphical itches-omni is using an old driver i think), but it´s not compatible so don´t test it as i have done.

OmniRom is using something special here, just Alucard has a special Omni Version which is working as it should.

Running v1.2.0 beta 2 with my own profile.

Sleeps like a kitten, wifi flies (disabled wifi optimization), cool as ice! No problems encountered so far. Top notch work my friend.

Edit: any chance of implementing the new intelliactive governor and fast charge option from faux?

That would be awesome.
[Galaxy S 4 i9505 Original Android Development] Lucius1972:
Hi teksin,

I have 1 bug to report for beta2.

I suddenly lost access to my internal storage, noticed that when I used some explorers (x-plore, es file Explorer) only showed the the KTweaker app rest was gone. Couldn't use airdroid eather, access denied.
[Galaxy S 4 i9505 Original Android Development] teksin:
Thanks for your feedback ! I'll fix it this night :)

For intelliactive, it's a nice idea, I'll probably add it to the next release (with GE Edition).

Have a nice day :cowboy:

How does this kernel compare to Alucard? I don't OC or UV. I just want the best battery life possible w/o it hurting performance.
[Galaxy S 4 i9505 Original Android Development] aleksik:
+1
[Galaxy S 4 i9505 Original Android Development] !crazy:
Alucard is more compact and saves energy like that. It is also faster, since it includes much more governors, but less code. Efficient OC of the GPU provides stronger flame, better fire, in efficient kernel so I would say it is stronger, more powerful. Because it is in possession of more power one gets impression it is efficient . The governors and tweaks make efficient kernel, more... Well efficient.

On 2.0.0 the sound subsystem is coming out from sleep mode too slowly. I can't hear the first half of the navigation guide's first word. It's not about CPU speed or governor.

[Galaxy S 4 i9505 Original Android Development] Lucius1972:
Hi try intelliactive governor, it's a combination of the interactive and ondemand governors and already tweaked for optimal performance.

Running it now for 2 days and I'm impressed!
[Galaxy S 4 i9505 Original Android Development] Chelonee:
Would you post your battery results with this kernel? I used version 1.0 for a while, but had some problems with it and switched back to KT Kernel. I'm curious what kind of battery life you can get with the new version of efficient kernel :)
[Galaxy S 4 i9505 Original Android Development] Lucius1972:
Hi Chelonee,

Efficient kernel as default is already tweaked for good battery.

Teksin really did a good job here.

With the default settings I could get +- 5 hours screentime if I remember correctly, I am now on intelliactive governor with my tweaked BFQ i/o, 2 hours screentime still 62% juice.

You can also grab one of the scripts from the KTweaker shop and load them up, they will run perfectly with efficient as it is based on ktoonsez kernel.

Pls be aware that every person uses his or her device differently, so posting screenshots of the bat usage is irrelevant.

Good luck.
[Galaxy S 4 i9505 Original Android Development] Chelonee:
Hi Lucius, thanks for your reply :)

About 5 hours screentime sounds good. I know that battery life varies between user/device/rom/kernel combo, I don't post much, but I read a lot in the forums. :D

I still think that battery usage gives a hint on how well a kernel performs.

Thought about giving the new version of this kernel a try. Thanks again, I appreciate this. :good:
[Galaxy S 4 i9505 Original Android Development] Lucius1972:
Just flash v2.1.1 and load provided efficient settings (2.1.1) in KTweaker. This should give you a good starting point.

[Galaxy S 4 i9505 Original Android Development] Z-Blade:
Not sure how you did it Teksin but you definately have refine what Ktoons has done. I get a better battery life and a noticeable performance boost. What amazes me is I no longer get deeps sleeps, I get coma states! I went to sleep at 11:30pm with 77% battery and woke up with 77% battery life. At first, I thought it was some mistake but for the past 3 days, I have only got 0%-1% battery drain in the 6-7 hours I sleep.

Getting 6 hours on screen time is now the norm for me, I have my own custom settings from when I was using Ktoons and the only thing I have changed is of course the governor to your efficientdemand. Keep up to good work and I hope you are able to tweak this kernel even more.
[Galaxy S 4 i9505 Original Android Development] teksin:

[Galaxy S 4 i9505 Original Android Development] Vladivid:
I noted that efficientdemand governor badly works when playing music. Sometimes the sound stammers or starts decelerating speed. I used intellidemand governor in case of the screen off and it corrected a situation. Whether it is possible to improve efficientdemand governor for operation when playing music?
[Galaxy S 4 i9505 Original Android Development] Z-Blade:
I spent about 1 month tweaking the voltage to the point where if I decrease it by 5mv on any steps, will cause the S4 to crash. As an example, I got 189mhz set to 700mv and at 1890mhz I got it set at 1145mv. Set GPU to -150mv across the board but in my opinion, GPU UV does not work with the default as I have had the low, nominal and high all set to 600mv and the S4 still runs perfectly fine.

I don't want to put the voltage table on all steps mainly because each S4 is different. Governor is Efficientdemand but planning on trying out the others. Scheduler is BFQ.

Min: 189Mhz

Max: 1890Mhz

Another big player in my S4 running so good with good battery life is Comadose.
[Galaxy S 4 i9505 Original Android Development] teksin:
Which rom do you use ??

Maybe the undervolt...
[Galaxy S 4 i9505 Original Android Development] Vladivid:
CM11. But the same effect and on SlimKat. I don't use undervolt, all settings from 1 post, I didn't change anything else. On Efficientpower governor too everything is good. Problem only on Efficientdemand... Only at me so?

P.S. Or meant already existing undervolt? Perhaps it is worth increasing values? It is necessary to try.

Thanks for your work! Your kernel - the best! :)
[Galaxy S 4 i9505 Original Android Development] teksin:
Can you check the "screen off profil mhz" in the extra settings ? try to put it to 486 mhz. I hope it will fix it !
[Galaxy S 4 i9505 Original Android Development] Vladivid:
I tried - doesn't help. I put even more. Probably, for my phone values for frequencies are small. I will increase values and I will unsubscribe then.
[Galaxy S 4 i9505 Original Android Development] asbanoglou:
I had the same problem on version 1.0.0 but after i flashed 2.0+ and effecient settings for ktweaker app the problem doesnt persist anymore.I havent changed anything though :)
[Galaxy S 4 i9505 Original Android Development] Vladivid:
Strange, probably, doesn't love my phone of the strong undervolt... I put 850 for the frequency of 378 Mhz and only then problems disappeared. Though for some reason on a governor of intellidemand such it isn't watched even in case of low values of a voltage. Strange...
