[Q] SmoothnessRequired

Guys i'm using serduPetru stock .13 JB rom with serdu OC kernel
Is there anything i can do to make my tab smoother, a tweak or another kernel, (something compatible with my rom ofcourse)
I realise that i have quite the number of widgets on , but for a quadcore tablet running JB , i expected things to be a lil' bit smoother ,
I dont care about benchmark stats, i just wanna something that's buttery smooth with decent multitasking
Thanx in advance guys

try cleanRom 3 and flash clemsyns kernel after and you will see real smoothness

Is this kernel compatible with my current rom??, dont have the time currently for flashing a new rom

[Kernel][30-05][GT-I9305][Update 10]--Boeffla-Kernel 2.11 stable!

AndiP Boeffla kernel v2.11 stable compiled for GT-I9305.
!! This kernel is intended for Samsung based ROMS 4.1.x (Until Samsung release 4.2.x source) !!
The kernel is recompiled with the required changes so it will work on our I9305.
Changes i made between the I9300 kernel.
No FM-radio
Removed CMA device memory allocation (We dont need that with 2gb ram)
Removed Load and flash kernel script from Boeffla site (The site doesn't have I9305 kernels atm)
Patched Boeffla_Sound driver to work with I9305 soc (Thank's to Andrei for his swithes to his code)
Compiled with stock ARM 4.7 toolchain
Based on latest Samsung Update 10 source code
Everything else is like the I9300 kernel.
.:The compile-port and tests made by me and only me:.
Please for any questions problems or anything else ask here and not on I9300 thread.
All credits for that kernel goes to AndiP for the work and updated sources also for allow me to release that port.
And also AndreiLux for help me understund a lot of thinks about compiling.
Important note copied pasted for AndiP's I9300 thread:
Is recommend strongly to reset all kernel configuration to default settings before flashing the new kernel (Tap "APP: Reset all settings" in Boeffla-Tweaks app) and configure your settings again after the flash. This procedure is required this time to avoid side effects.​

Thank's​

Thank you

Thanks once again
I'll test this a test drive

Very nice kernel, very flexible and I LOVE the sound mods.
Just a quick question, I noticed that there are Boeffla sound settings in the Boeffla Tweaks app.
Do we stll we both the Tweaks and Sound app?

Can I ask a small favour and get somebody to post some good CPU / GPU settings to get me started with some good tweaking / overclocking?
This is one thing I dont really know a hell of a lot about lol

Did anyone found any problem??
Try to read the boeffla site to see the diff..
I found it stable. If not i can also compile and upload the 2.9 version.

It worked for me, the Boeffla Sound tweaks are amazing !!
Still don't know enough about setting up a decent overclocking on the CPU and GPU tweaks.
If someone can give me the setting for a basic overclocking on CPU / GPU I can give it a good test with benchmarks, games, apps etc.
The latest release would be nice though however, and include the Boeffla Sound App if its required please
TIA...
EDIT: Found this page: HERE
Seems to be very explanatory...

Re: [Kernel][GT-I9305][Update 9]--Boeffla-Kernel 2.10b2 ported!
Hey guys can I apply this kernel to my i9305 via cwm & after install do I have to do anything else? I'm running CM 10.1 nightly.
Thanks in advance.

NO! This kernel is for 4.1 stock based ROMs. IIRC CM 10.1 is based on 4.2 android.

This kernel gets the thumbs up from me, FINALLY a good customisable kernel with good sound features.
I'm running this kernel on both my phone and my partner's phone (as she really needed a good fix for USB Charging), and we both couldn't be happier with the performance improvements. Two nice changes noticeable were in games, plus the sound quality when we plug the phone into our car via the headphone socket.
This is the config I used for both phones, any options not mentioned were left as default.
Boeffla Sound
- Advanced Tuning -> Speaker Tuning ON
- Tuning -> HW Equalizer ON
- Tuning -> Graphical Equalizer -> Presets -> Bass+Treble Balance
Boeffla Tweaks
- CPU Max Frequency: 1500mhz
- GPU Frequencies: 266/350/440/533
- Sharpness Fix: ON
- AC Charge Rate: 1200mA
- USB Charge Rate: 900mA
I still don't know a lot about the Boeffla Tweaks, but this seems to be a good starting point. Maybe some other people can share their configurations as well...

Re: [Kernel][GT-I9305][Update 9]--Boeffla-Kernel 2.10b2 ported!
I have noticed that hotpluging of cpu cores doesn't work nice with this kernel. I had similar but different issue with perseus kernel.
With boeffla three cores are always active. After reboot there are 4 cores and after a couple of minutes or less third core goes off, and it stays like that. Changing governor doesn't help.
Anyone else with this problem?

Awesome job on the Kernel!
And thank you for all your porting efforts
Any chance you could port the latest stable version of this kernel?
Or maybe a port of the 4.2.1 Android Revolution 30.5 Rom?

Yes i can port also the 2.9 stable but i dont find any reason for that because i see the 2.10 is also stable.

As you know Samsung doesnt release the sources for 4.2.x kernel so i cant work on that part.
Until samsung release the sources then i can port it to I9305.
Thank's

After wipe cache and wipe dalvik cache the microfone dosen't work, only flash an other kerne (perseus) sloved this problem!...i Flash back to this kernel and 1st all works fine, after wipe microfone is broken again

Battery is dead after 4 hours of gaming/browsing or standby?? Use Performance Control to set up the kernel right Android 4+ uses virtual ram taht may slow down the performance. Set swappiness in vm settings to 30. Keep in mind that zRam should be not more than 25% of the physical ram. Set sdcard read value to 512kb or 2048kb. Try different combinations of scheduler/governour. Don't overclock the cpu/gpu if the device already becomes hot.
In many cases the presetted kernel config is just kinda crappy and you can gain a lot by matching it to your needs

You got the Latin American version. Its made for other Cellular Networks than the international version
CM10.1 with 2.6 based kernel --> LINK should work better than the CM11 build
And a alternative CM 10.1.3 build --> LINK

Kernels, must have a ROM ?

So, do you need a specific ROM for specific kernels? Or can you download kernels without a ROM?

If possible to download kernels, can someone link me to a list of them if that's how it works.

I know I am sounding like a total noob right now, I've flashed ROMs many times but don't know much about kernels

@jongonzalez716705
Of course you can flash a kernel without a rom.
Make sure that the kernel is compatible with your current rom.
Profits about a kernel;
+ Some kernels let your overlock your processors
+ faster boot time
+ some kernels have some other advantages.
Which phone do you have?

I know but I've downloaded a ROM before that had its own custom kernel. Had fun overclocking but spent more time underclocking. Is there somewhere where I can download certain kernels?

Yes,you can flash Kernels.
Why are custom kernels android useful?
Ans:Kernels are the brain of your Android device and communicate between software and hardware. Therefore, they are responsible for managing things like CPU / GPU clocking speed, screen sensitivity / colors or voltage. By using a custom kernel you can not only improve battery life, but also increase system performance.
Many custom ROMs already come with their own kernels. This is done to implement software communication of the custom ROM with the hardware of the device and also to ensure a better performance. Nevertheless, you are often also able to flash custom kernels to custom ROMs. If you decided to stick to a rooted version of stock Android, flashing a new kernel can offer you additional performance with the convenience of a stock OS.
Always make sure to check compatibility of the kernel with your ROM and device, because flashing a wrong kernel can brick your phone!
You can use this apk called as Franco.kernel. The app is available in playstore.

Yeah I was wondering this too....
Is it possible to take my original rom kernel (built for mediatek 6582) and use it on say cyanogen ?

How is it going bro's and my name is Pewdiepie
Ok I am Using Cyanogenmod latest nightly I think on my Tab 2 gt - p3100 .
I want to ask should any kernel
I mean many are saying it will fix the battery drain:laugh:
But is it recommended for advanced users or only Developers
And which kernel you think is the best for battery and compatible with CM11
Please help me:highfive:
Peace and please don't hate

No you didn't have to.
I think,stock cm kernel 3.0.31 pretty much has good battery life.
Upstream kernel changes to 3.0.101 did causes battery drain and tried to resolve by devs.
However 3.0.101 have bigger free ram next 818mb, dhollmen 820mb, however agni kernel has same with stock cm kernel.
All those custom kernel offers some features which stock kernel didn't have.
Slightly different with android-andi kernel which purpose to find kernel battery drain for 3.0.101.
