Hello,

I installed the Kernel yesterday and am OK with it right now, besides of some random reboots.

I read that all features of VoLTaqe Kernel are included.

But I am not able to change the frequency of the GPU, as well as I am not able to change the GPU voltage. Is that a planned feature?

Other than that, I can only change the CPU frequency in 100Mhz steps. Especially in the lower frequencies, I would prefer to change it in 50MHz steps.

Thank you for your work anyway
[Galaxy S 4 i9500 Android Development] asad007:
GPU voltage control is with synapse

I removed synapse support cause people choose the wrong values and then complain here

50 MHz steps will be useless.
[Galaxy S 4 i9500 Android Development] body150165:
Yes. I saw that Synapse gives me a "no UCI support" - message.

I had good and stable experience with GPU frequencies set to min 177 and max 350. I didn't undervolt anything in the GPU.

Do you plan to add some GPU handling again?
[Galaxy S 4 i9500 Android Development] asad007:
GPU control is there

It only needs synapse support

I'll add it if most people prefer it

Further please ask such questions on Q/A thread
[Galaxy S 4 i9500 Android Development] zozoz13:
GPU Control feature is already exist in the kernel, as all VoLTaqe kernel feature is there. What we need is bringing back Synapse support. GPU Control only works with Synapse.

[MENTION=4296690]asad007[/MENTION] If allowed, I would like to make a suggestion. You can make two versions, one has support at Synapse and the other one does not. OR you can make an add on for who want Synapse support, like me. Just a suggestion :)
[Galaxy S 4 i9500 Android Development] asad007:
I'm thinking of adding synapse support without all the confusing features

Only basics like

CPU

GPU

Sound

Screen
[Galaxy S 4 i9500 Android Development] zozoz13:
Yeah, thats all what i need, especially Screen and sound control. Thank you ;)
[Galaxy S 4 i9500 Android Development] asad007:
Added synapse support

kernel is same
[Galaxy S 4 i9500 Android Development] deepak179:
Yes ...this is what we should aim at. Simple, stable kernel with CPU and Voltage control ability.
[Galaxy S 4 i9500 Android Development] yesh8352:
Im on 2G:(

Anyone here with RR could provide Boot.img?
[Galaxy S 4 i9500 Android Development] body150165:
Thank you for providing 13.1

Not sure if my post is correct here or if it belongs to Q&A.

Unfortunately, I was not able to flash it. I tried 3 times but was stuck at boot logo or "optimizing apps" or turned off by itself while initializing.

First try, I only wiped cache as mentioned in OP

Second try, I wiped cache and dalvik

Third try, I wiped cache, dalvik and preload

Didn't work. Some times, only battery pull helped.

Not sure if I have a corrupted file due to bad download or if something wrong with the kernel. Does anybody else have this problem?

Hi [MENTION=4296690]asad007[/MENTION], I'm with Aurora S6 v4 ROM and your v12.2 TW kernel and is working fine. But, above that version my phone is unstable, with FC and reboots with all superior versions... Why is that? Is someone testing TW versions?
[Galaxy S 4 i9500 Android Development] Aisfkhan:
can i flash this kernel on omega v28?
[Galaxy S 4 i9500 Android Development] asad007:
I don't test the TW version cause I'm personally on gearcm

So you guys need to confirm whether it works like it should or not

Further if you change voltage settings you will have instabilities

Also Ported Roms always give you problems.
[Galaxy S 4 i9500 Android Development] tanqueta207:
If nobody test TW kernel is funny that is posted like it works fine. Last 3 versions aren't working in Aurora S6 v4 ROM... Someone with official TW that can assure it works fine?
[Galaxy S 4 i9500 Android Development] asad007:
The kernel for tw is not much different from cm , the only thing is that front facing camera code and selinux is different on cm

I used stock defconfig to compile the kernel (with little modifications)

TW version should boot fine.

If it doesn't , tell me I'll try to fix

And if you find xda funny don't come here and waste our time.

You flash the kernel at your own risk not mine. [MENTION=4268599]tanqueta207[/MENTION]

Updated the OP for you :)

Where's [MENTION=5709742]newfern[/MENTION] ?
[Galaxy S 4 i9500 Android Development] body150165:
I tried to flash it 5 times. Even downloaded the file again. Always clean flash.

13.1 (TW) doesn't boot up. 13.0 is fine.

Sorry for the bad news.

Running Prism Barebone V16
[Galaxy S 4 i9500 Android Development] :
Using Halycon v9.0 ROM, flashed the 13.1 version, phone boots up but hangs after few minutes (even after force reboot). Cleared Kernel adiutor (the app Im using) and also cleared cache/dalvik. Any help?
[Galaxy S 4 i9500 Android Development] tanqueta207:
I posted some messages that this kernel isn´t working but if you don´t tested yourself is imposible to fix it. It's hanging after 15/60 seconds using android.

If you only cares about CM post that kernel, because the TW one is not working since 12.2 and is "funny" that you keep upgrading version number when is broken.

I want to use your kernel dude, only it is not working.

Thanks.
[Galaxy S 4 i9500 Android Development] body150165:
I am using v13 (TW) at the moment. Stable.

Agree that 13.1 (TW) is not working.

[Galaxy S 4 i9500 Android Development] gp545:
Sorry, but not trying to offend you..

If current version isn't working then there's always one way "Revert Back" to old version.. V11.5 is most stable for me.. (If you don't have this version then, will provide you the version).

Good thing is you're testing the versions that are being released here and using free time to post about it ?

But please do not discourage the one who's trying ?

Check PM
[Galaxy S 4 i9500 Android Development] bilicool:
Buddy can you please provide the link for 11.5...it would be really helpful to me. :)
[Galaxy S 4 i9500 Android Development] nevinjoseph:
Try 11.7. It is even better than 11.5.. The performance is better and is more stable. I'm using v11.7 on my s4 on aurora 8.2 Tom and I'm getting excellent battery life
[Galaxy S 4 i9500 Android Development] ficeball:

Thanks a lot [MENTION=4296690]asad007[/MENTION] for your work, but in Aurora S6 v4.1 ROM I'm getting bootloop with version 13.5.2. It seems that that some ROMs have problem with your kernel . Like I said this problem is present after v12.2 when you use Voltaqe as base source, in version 13.0 and 13.1 I was getting freezes after 15/30 seconds of use just like it was happening in last Voltaqe TW release. It would be nice if you could upload the lastests Stable/All ROM working kernel in the OP, that it's seems to be the v11.7.

Again, thanks for your efforts, say if you think that you could repair the kernel for all ROMs if not I will change mine.

I'll extract the ramdisk and put it with my kernel and add to OP ( different versions for different ROMs , this may solve the problem )

Right now 13.5.2 has OD4 ramdisk from prism ROM v16 which is stock OD4 only

The developer is the owner of the kernel therefore he owns all rights to the kernel. I can only do so if the developer grants me permission to do so.

[Galaxy S 4 i9500 Android Development] nevinjoseph:
Is that the 11.7 classy test version? I'm using that and getting superb battery life. Is anyone here using v11.5 who can do a comparison of battery life of both variants? Having tested both, I can confirm that v11.7 is the better version in terms of stability, performance and battery. I wish [MENTION=4296690]asad007[/MENTION] could post the download link of v11.7 as a stable release on the OP
[Galaxy S 4 i9500 Android Development] galaxydroid_19:
Yep.

BTW, which rom are you using?
[Galaxy S 4 i9500 Android Development] yuber26:
Thx mate ;)
[Galaxy S 4 i9500 Android Development] nevinjoseph:
I'm using Aurora N4/S6 port v8.2 debloated and tweaked further for maximum battery savings.
[Galaxy S 4 i9500 Android Development] galaxydroid_19:
Can you tell me what are the tweaks you're using?
[Galaxy S 4 i9500 Android Development] nevinjoseph:
I don't use any battery saving apps like Greenify or Amplify xposed module. I believe they do more harm than good. The way i have been able to achieve good battery life is by being able to let my phone go into deep sleep as soon as I lock the phone. In the ROM side, I have tweaked the build.prop and set the pm.sleep_mode value to 1 which offers the best battery savings. Also set the wifi.supplicant_scan_interval to 420

My Kernel settings are as follows:

I use Kernel Aduitor for tweaking the parameters btw

Kernel version: LWK 11.7 Classy

Max frequency : 1600MHz

Min Frequency : 100MHz

CPU Governor : Ondemand

Schedule work queues : enabled

CPU Voltage : Global offset -100mV

Screen settings: Register hook and Master sequence is disabled

IO Scheduler settings:

Int storage : noop 256kb

Ext storage : noop 512kb

Enable ksm : on

deferred timer : on

LMK, VM and Etropy values all stock

I also have disabled power save mode on battery settings as I get better results without enabling it.

I enable sync only at night when I plug my phone for charging.

Brightness is set to the lowest value when using phone indoors and auto brightness enabled when outside.

Also I use a kiwibird case with an additional 2600mAh battery which gives me an average screen time of 10 hours.

Hope this helps.
[Galaxy S 4 i9500 Android Development] galaxydroid_19:
Couldn't ask for a better answer.

Thanks!

Last question:

Your ROM has bugs?
[Galaxy S 4 i9500 Android Development] nevinjoseph:
I'm using Aurora 8.2 as my daily driver now. Tried 8.5 but the call quality was very poor and hence reverted back. Apart from a few bugs here and there, Aurora 8.2 is a really solid and stable ROM. It doesn't have the annoyances like random reboots or freezing issues. That is why I use this ROM as a benchmark to assess the battery life, performance and stability of kernels. 11.7 works great with this ROM. The bugs I noticed are : The inability to set PIN number as security for the lock-screen and the inability to turn on services in accessibility menu.

I just tested and it doesnt work with Peel smart remote or the Samsung remote app. I was pretty surprised actually cause I haven't really used the remote app in a long while and never knew that it didn't work until the query was raised.

So that raises another question. Is the IR working in the later versions??

Please continue TW version. It's still not sure if VoLTaqe will continue the S4 version.

If you also back off from it, it will leave us with not having any custom Kernel.

Since CM12.1 is still not reliable, I would appreciate if you don't forget about the TW users.

Thanks for consideration.

[Galaxy S 4 i9500 Android Development] nevinjoseph:
Try perseus kernel for i9500. I've been using perseus when I was on kitkat and it works great with loads of customisation and synapse support. But lollipop roms have improved a lot in terms of battery backup and stability especially the ported roms. Don't think you can to get the same level of battery savings as on lollipop roms with perseus kernel.
