I tested the last kernel (151006) on Diderk build and same problem like official cm11. After install it works like a charm, but after a while it freeze the phone and restart.
[Galaxy S 4 Mini Android Development] lombartz:
I made my own CM11 build yesterday and a new kernel, runs fine so far.

All vulnerabilities seem to be fixed. I first ran with the stock kernel and couldn't believe how slow that was compared with the lombartz kernel...:eek::cool:

I will test a bit and post the new kernel if all is o.k.

Anyone interested in the new CM11 build ?

Maybe it's time for a "lombartz light" version with less agressive OC/UV.

Anyone else out there who would like to try ?
[Galaxy S 4 Mini Android Development] RuffBuster:
Cm11 is now my daily driver. I'd be interested in testing your kernel builds. Is your cm11 basically the same as didierks build with the latest stage fright patches or does it include any new commits?
[Galaxy S 4 Mini Android Development] Kopaxi:
Yes, i'd like to test the new kernel and your new rom too ?
[Galaxy S 4 Mini Android Development] lombartz:
It's a pure build from the latest CM sources without any further patches. Tested for stagefright v2.

Building the lombartz light kernel atm...
[Galaxy S 4 Mini Android Development] lombartz:
Update

Two new Versions, one "light" version for users who had no luck with my kernel so far. May this one work for you ...

Updated Stock kernel.

Link to my latest CM11 ROM.

regards,

lombartz
[Galaxy S 4 Mini Android Development] Kopaxi:
I test the kernels. What is your suggestion for io settings? Fiops or sio?
[Galaxy S 4 Mini Android Development] lombartz:
... the default of course ;)
[Galaxy S 4 Mini Android Development] Kopaxi:
Can I dirty flash your rom up to cm11 official snaphot?
[Galaxy S 4 Mini Android Development] mick711:
It's a CM11 upgrade so repo base is the same , why not upgrade i test it if it's good i'm on last snapshot like you
[Galaxy S 4 Mini Android Development] lombartz:
I did a dirty flash without any problem. The only issue i had was Xposed: framework nit working..

If you use Xposed you need to replace two files with older versions. I'll add a flashable zip to OP.

regards,

lombartz
[Galaxy S 4 Mini Android Development] lombartz:
I need some feedback about the "light" version.

Does it help anybody ?

Maybe it has to be a bit finetuned.

I only will update that version if it is useful for somebody.

v20151115_a in OP.

regards,

lombartz
[Galaxy S 4 Mini Android Development] haloass65:
Runs Good

Well im using your light Kernel and no random reboots so far :)
[Galaxy S 4 Mini Android Development] Kopaxi:
I'm using the light version too and in the last 23 hours i didn't recognize any reboot :) It seems it working as it should be. The speed is ultra high like in the previous versions and battery drain is same like with cm11 official. For me it is better than last CM11 original kernel or F4K 2.1.0 :) Nice work Lombartz! :D
[Galaxy S 4 Mini Android Development] :
Yes, I installed your latest rom and light kernel on my partners phone. It's running well so far. I might have a look at the tunables in a few days and give some feedback, but no complaints here
[Galaxy S 4 Mini Android Development] RuffBuster:
Not had a chance yet, but come tomorrow I will be giving it all a good testing. But sounds good so far from others.
[Galaxy S 4 Mini Android Development] lombartz:
Update

Sorry guys had another idea this morning ...

[Galaxy S 4 Mini Android Development] Kopaxi:
It seems that sometimes the screen wake up by itself when pull the phone from my pocket without any button press. Can i disable this anywhere?

Anyway the 151116a kernel has much battery drain in deep sleep than 151115 (as i see)
[Galaxy S 4 Mini Android Development] RuffBuster:
I've been using CM11 for some time. In comparison I'm finding your latest 13/11 build and 16a/11 kernel to be on par if not faster than my previous CM11 build with F4K kernel. Battery standby for me feels good. Last night's battery drain around 3-4% over 7 hours.

I haven't noticed any strange behavior yet, like screen turning on itself?? I did have 1 reboot on 14d/11 kernel when installing apps from play store and doing other things at the same time. But no issues or reboots using FULL VERSION 16a/11 with your 13/11 CM11 build.

I'm very happy with performance so far, though it's only been a day. In the past my phone never used to like your kernels, but now it seems all good!
[Galaxy S 4 Mini Android Development] RuffBuster:
OK I have suffered 3 random reboots over the last couple of days using 16a/11 kernel. Think my phone isn't as strong as yours. But now using your "lite" version of 16a/11 and so far seems to be running great. Fingers crossed. Personally I'm finding your normal and lite versions to be same performance and battery wise, which is far better than stock kernel. Many thanks for your efforts!
[Galaxy S 4 Mini Android Development] RuffBuster:
Using the "lite" version of 16a/11 with your CM11 build is great for me! I'm loving it! No random reboots. I find its almost the same battery usage, but so much smoother and quicker than my next favorite kernel. What exactly is different between lite and normal?
[Galaxy S 4 Mini Android Development] :
AFAIK lite is stock cpu clocking (1.7 ghz) and less aggressive ramping and gpu settings. Normal version is 2 ghz(OC) clock speed and more aggressive. Both have ecoactive gov.
[Galaxy S 4 Mini Android Development] lombartz:
Simply explained : all frequencys 2 steps lower, all voltages 1 step higher (still 1 step lower than stock)

All the rest is identical.

performance is approx in the middle between stock and normal version.

As i can read out of your posts your phone is nearly capable running the normal version.

regards,

lombartz
[Galaxy S 4 Mini Android Development] lombartz:
This cannot be caused by the kernel. I bet you would have the same problem with the stock kernel, too. Please compare ...

Maybe this is caused by the same reason as your wake up problem ? There's nothing changed in the 16_a kernel wich could cause higher deep sleep battery drain but it should consume a bit less power under load along with beeing a bit slower compared with the 1114/1115 versions (wich are quite similar) . I think i will revert this in next version.

Testing a new kernels performance and power consumption is always problematic because often it is not reproducable from boot to boot because of varying network strength and background activity.

regards,

lombartz
[Galaxy S 4 Mini Android Development] lombartz:
It's not stock clocking, stock ist 1728 MHz and lite is 1782 MHz (because of the 108 MHz steps). ;)

L2 is also higher than Stock.

I'm thinking of giving the next light Version 1890 MHz, what do you think ? RuffBusters Phone should be able to handle that ...

regards,

lombartz
[Galaxy S 4 Mini Android Development] :
Ah, thanks for correcting.

I've been playing with the kernel tunables to keep my partner happy and have gone the other way(more battery friendly) as she isn't a heavy user and would rather not have to charge as often. I don't mind if you make the next higher, anyone can adjust it to their needs anyway. Thanks for your work, very happy here with your CM11 and lite kernel. :)
[Galaxy S 4 Mini Android Development] RuffBuster:
Maybe having a step higher in clock speed would be nice, but having more battery while staying smooth is my main concern. I'm just happy this runs a lot smoother than stock. I can feel with it with everything I do compared to stock. I haven't even been tempted to mess with the settings.
[Galaxy S 4 Mini Android Development] Kopaxi:
Ok, now i realised the wake up problem and it not caused by the kernel, but the rom. Because I forgotten that installed your rom I got back the home key wake up, so every time I pulled out the phone from my pocket the phone woke up by pressing the home key. I disabled it in the last rom, before yours, so i didnt know what caused this wake ups. Sorry guys that was my fault ?
[Galaxy S 4 Mini Android Development] marto777:
My phone is I9195 but its with installed CM11 3gs for I9190.Can i install this kernel
[Galaxy S 4 Mini Android Development] Member123456:
Omg bro you did a great work..the kernel is Working so freaking good for now..hope it doesnt reboot lol..thanks a lot buddy.
[Galaxy S 4 Mini Android Development] tinko975:
great
[Galaxy S 4 Mini Android Development] lombartz:
Kernel Update

If your full battery display falls a bit faster at the beginning don't worry about that.

It's only the display hopefully working more linear now.

We'll see...

regards,

lombartz
[Galaxy S 4 Mini Android Development] tinko975:
Best rom and kernel for S4 mini. Works with full speed ahead. Thanks.
[Galaxy S 4 Mini Android Development] lombartz:
It seems the last patch finally has solved the ugly battery status display.

You can now use the phone down to 10% battery level without the danger of a sudden shutdown.

I changed the full version in OP back to 20151201_e because of earlier scaling down from max frequency. It's still fast enough ...

regards,

lombartz
[Galaxy S 4 Mini Android Development] haloass65:
Kannst du alle Kernel hochladen ? :)
[Galaxy S 4 Mini Android Development] lombartz:
For what ? If somebody is not satisfied with the actual Version or found an older version to be better he should post it here. This helps to improve things further.

lombartz
[Galaxy S 4 Mini Android Development] Poluxor:
Guys

Could you give me instruction steps by steps how to install this on my s4 mini?

Now i have got http://xdaforums.com/galaxy-s4-mini/development/rom-t3030976 on my phone.

Can i count you guys?
[Galaxy S 4 Mini Android Development] haloass65:
Your kernel (Lombartz_DYNABOOST_Kernel_20150507_c_1890MHz.zip) works like a charm

Thats why

greetings
[Galaxy S 4 Mini Android Development] lombartz:
Ok, that was a full version with reduced max freq. Can you please tell me what was better in that version ?

Or is it only you want a 1890 MHz version ?
[Galaxy S 4 Mini Android Development] haloass65:
Yea a full version with reduced max frequence

The gaming performance is way better than ur light kernel

Can you increase the CPU Voltage by 25 mv just like your light kernel ? :)
[Galaxy S 4 Mini Android Development] lombartz:
Attached Lombartz_custom_1890MHz_ECOACTIVE_CM11_Kernel_20151214_a to OP.

1890 MHz max. freq.

+25mV @ 1890 MHz, Rest same as lombartz full

some little gaming tweaks to ecoactive (remember: ecoactive will throttle down to 1350 MHz 10 secs after last touch, set fullspeed_phase to 0 to disable throttling)

not tested by me !!!

have fun,

lombartz
[Galaxy S 4 Mini Android Development] haloass65:
Thanks i will test it :)
[Galaxy S 4 Mini Android Development] haloass65:
Update:

No random reboots so far and the performace is pretty good ! Better than light kernel !

Can you compile a full kernel with 1.9 GHz clock and increase the CPU V by 25 mV or no UV ?

I am not sure if my phone can run it but i want to test it out. :)

Greetings
[Galaxy S 4 Mini Android Development] lombartz:
Why do you want to increase voltage further ?

That makes no sense and you could do that yourself via voltage setting.
[Galaxy S 4 Mini Android Development] haloass65:
The thing is that my phone cant run with your Full kernel,( Random reboots at lock screen)

thats why
[Galaxy S 4 Mini Android Development] lombartz:
Please understand:

The full version is already slightly overvolted at max. freq.

The lower freqs. are undervolted.

With more voltage at max. freq. your phone will overheat, throttle down and die sooner.

You now have a full version except the 108 MHz less max. freq. wich means about 5% less performance but running in the safe area.
[Galaxy S 4 Mini Android Development] haloass65:
Okay no problem :)
[Galaxy S 4 Mini Android Development] mick711:
Hello

The light ecoactive kernel is amazing very very good battery life

I test before the 1890 and i see some pick of battery drain when i not use the phone, don't know why so i go to the light ;)
[Galaxy S 4 Mini Android Development] lombartz:
Hi and happy new year !

Your Impression is totally right !

the 1890 version is a bit more "active" than "eco" because it has no idle up delay. It is better for realtime critical applications with relatively low cpu load at the cost of some battery life.

The other versions wait a little longer before scaling up from min frequency. This saves battery but can cause micro stuttering in some situations. Maybe a version with idle up delay only when screen is off would be perfect ...

Thanks for your feedback ...

regards,

lombartz
[Galaxy S 4 Mini Android Development] DonQuichotte:
Hello Lombartz,

do you plan to release any new updated builds?

planst du neue aktuelle Versionen zu bauen?

Thanks for your previous build, running very stable.

DonQ
[Galaxy S 4 Mini Android Development] lombartz:
Thanks for your Feedback - the problem is that I have no idea what to improve further. ;)

We have the fastest and most efficient kernel and a rockstable rom with the most important security patches for this phone.

Any suggestions ?

regards,

lombartz
[Galaxy S 4 Mini Android Development] DonQuichotte:
Hello,

I'm talking not asking for adding new features, just security fixes to be up-to-date and safe. Your last ROM has Android Security Level 01.11.2015 and the GT-5110 of my father already has 01.01.2016 and it's Android 4.4.4 too. So if you could build a new ROM, with security fixes integrated, whenever a new Security Level is reached would be awesome. I'd like to stick with KitKat as long as possible.

Regards DonQ
[Galaxy S 4 Mini Android Development] lombartz:
I think I'll build a new rom in February when next security level is out.
[Galaxy S 4 Mini Android Development] DonQuichotte:
Hello,

would be awesome...many Thanks in advance.

Regards DonQ
[Galaxy S 4 Mini Android Development] lombartz:
Updated ROM to security patch level Feb. 2016.

Hello Lombartz,

1st of all thank you for the new build, will flash asap. Can we still use the Kernels from OP

with this new build?

hi lombartz i tried your unoffical build of cm 11 2feb18 and installed open gapps arm pico 4.4.4.. when starting android first time setup when selecting language it crashes all the time cant get the first time setup done. by the way your kernel is good, but when using light ecoactive kernel and listening google music it sometimes stutters with defaut settings. i have gt-9195I (Serranoltexx).
[Galaxy S 4 Mini Android Development] Alefello:
Hi lombartz and thank you so much for your work

In the lastest version of your kernel is f2fs included?

Thank you! :)

can i use this kernel in lollipop 5.1 ?
[Galaxy S 4 Mini Android Development] kamikaze702k:
Maybe you can make a nandroid backup, flash, then let us know....

---------- Post added at 02:20 AM ---------- Previous post was at 02:15 AM ----------

What CM11 base is this?
[Galaxy S 4 Mini Android Development] Djwhitegold:
Lombartz, thank you so much for this excellent rom and kernel. My s4 mini is so fast and no longer draining battery as it was on stock rom. My phone has better battery life and performance. Thanks and best wishes!
[Galaxy S 4 Mini Android Development] Alefello:
Hi lombartz, I'm still using your ROM and I'm very happy with it but the internal storage of this device begins to be low, so I'm searching about moving the internal storage folder to the 2nd partition of the SD card. Actually the folder is located in /mnt/shell/emulated/0 and I tried to write myself a script which moves the data to the 2nd partition and then mounts the partition on the folder, but it doesn't work. Could you please help me to reach the goal?

Thank you so much!
[Galaxy S 4 Mini Android Development] Alefello:
Hello

I was very happy with you kernel, but if I change teh partitions to F2FS, it won't boot. I had to switch to f2k kernel to use F2FS file system, even if I prefer your kernel. Could you please check the F2FS support and fix it?

Thank you
[Galaxy S 4 Mini Android Development] dibbie666:
hello I have the rom and kernel installed for the i9195, have tried several other roms android oreo and others but still come back to cm11 .great results with this rom thanks
[Galaxy S 4 Mini Android Development] Tom Mix:
i second that

indeed: KK rules them all! the latter roms can't compete at stability/performance/battery/features/functions.
[Galaxy S 4 Mini Android Development] lombartz:
So the reason may be the OC/UV. I thought every device can handle this setting. If you like i can build a non OC' ed f2fs Version then we know if that was it.

In my kernel not only CPU and GPU are OC/UV' ed...
[Galaxy S 4 Mini Android Development] bongster:
That would be great!

Can I use performance control to UV by myself? I'm not really interested in oc as I'm not a heavy gamer...
[Galaxy S 4 Mini Android Development] spixy:
Thanks for this kernel :)

I actually have 20150212, should I upgrade to 0216, 0217 or just wait?
[Galaxy S 4 Mini Android Development] lombartz:
Don't use the 1702 Version, it won't boot.

You can use 1602 Version but that one has no more features than the stock CM Kernel, just the updates (Wifi,sound etc) since the last official CM Kernel.

The 1202 Version tweaks made the smartmax a bit too "nervous" in my eyes but nobody complained about that ...
[Galaxy S 4 Mini Android Development] vag12345:
I have a problem with battery drain even during night. I assume that it is due to the kernel as it happened after an OTA update. I am on stock rom 4.4.2 and i would like to know if i can use this kernel. Yesterday i just rooted it and installed Busybox.

I know that this isn't the proper thread for the second question, but could you advice me for what it may happens and what to do?

Thanks in advance
[Galaxy S 4 Mini Android Development] lombartz:
This kernel is only for CM11 based Roms, it may even work with carbon or Slim. Don't use it for Stock Rom.
[Galaxy S 4 Mini Android Development] vag12345:
Thank you for your answer. So the only way to change kernel, is to change the rom too (if the problem is due to the kernel).

I suppose that you don't know anything about the battery drain and how i can solve it...

Thank you again
[Galaxy S 4 Mini Android Development] spixy:
you can try f4ktion kernel
[Galaxy S 4 Mini Android Development] andrisrozkalns:
Maybe Linaro toolchain in your kernel?
[Galaxy S 4 Mini Android Development] lombartz:
update !
[Galaxy S 4 Mini Android Development] andrisrozkalns:
Delete.
[Galaxy S 4 Mini Android Development] spixy:
nice work :)

its like tweaked and updated version of f4ktion 2.0.0 kernel?
[Galaxy S 4 Mini Android Development] lombartz:
No, it's based on the latest original CM11 sources.

These were last updated on march 16.

The hardware parameters are adapted near to the limits of my phone.

This means this kernel will not work for everyone.

Here is an updated Version if you like, has an additional "hyperactive" default governor based on the stock interactive with input boost (thx Faux123) an some other tweaks.

have fun...
[Galaxy S 4 Mini Android Development] lombartz:
Update

added separate hispeed and input boost frequencys to hyperactive governor.

This allows to reduce the hispeed_freq and use a higher input boost frequency.

This gives a better input response while saving battery. Seems to work much better than the stock interactive and even the smartmax...

regards,

lombartz
[Galaxy S 4 Mini Android Development] 3x3l1x15:
i flashed your kernel via custom recovery and my phone stuck bricked in boot screen and the message "warranty bit: kernel) appears.. I tried anything but no luck

Thank you a lot pal!
[Galaxy S 4 Mini Android Development] lombartz:
Reading your post I assume the problem is most likely not the kernel ...
[Galaxy S 4 Mini Android Development] TheFixItMan:
I believe you get this when you don't disable knox when you root your phone & change the kernel but I haven't tested
[Galaxy S 4 Mini Android Development] nussbaum:
No problem with latest SlimKat here. Thank you.
[Galaxy S 4 Mini Android Development] lombartz:
Thank you for your Feedback. I'm thinking about trying Slimkat as well.

regards,

[Galaxy S 4 Mini Android Development] lombartz:
Update

...some changes in the boost logic and set boostpulse to 120ms.

have fun,

lombatz
[Galaxy S 4 Mini Android Development] TheFixItMan:
ok so iv done some testing

the warranty bit: kernel appears because you have changed the kernel from stock

the same as warranty bit: recovery appears when you enter a custom recovery

Anyway the kernel works fine and boots up cm11 with no problems - im guessing that guy either has a different model of phone or is using it on an unsupported rom

No problems with me

thanks
[Galaxy S 4 Mini Android Development] lombartz:
Update

- one new cm commit

- tuned mdnie profile "dynamic ui" scenario 0 mode 0 to less clipping and blue-green shade in dark and bright areas

if you dont like the colors, use previous version and leave feedback here.

[Galaxy S 4 Mini Android Development] Mogs1:
Will this work on aicp kk
[Galaxy S 4 Mini Android Development] lombartz:
I think so ... test and report here please.

You should make a backup before testing this kernel anyway.
[Galaxy S 4 Mini Android Development] Mogs1:
Working great on aicp thanks one problem is i cant get back to F4ktion kernel without getting bootloop but happy with your kernel
[Galaxy S 4 Mini Android Development] lombartz:
Hm, you can try to delete the 20frandom from the init.d.

If that dosn't help replace all the replaced files in system/lib with those from your original rom zip file (you can look inside my kernel zip file to find wich files to replace).

regards,

lombartz
[Galaxy S 4 Mini Android Development] Mogs1:
My battery seems to be heating up a lot with your kernel but stays nice and cool with f4ktion
[Galaxy S 4 Mini Android Development] lombartz:
This only can happen if you put your device on heavy load with a benchmark, reboot your device several times or something like that perhaps while with charger plugged in.

The reason is that compare to f4ktion kernel in my kernel the cpu is allowed to get 10° C warmer before reducing speed.

There's nothing changed regarding battery.
[Galaxy S 4 Mini Android Development] xDruidx:
It's funny. My phone became much cooler with this kernel + SlimKAT. That kind of problem you are experiencing, I got with the f4ktion kernel + LP combo.
