My Dhollmen kernel.
Galaxy Tab 2 P51xx : STOCK ROM compatible.
Sources in GitHub: https://github.com/Dhollmen/Espresso-Kernel
Credits for Kernel Team, Google, Samsung, and anyone with merit.
Linux kernel 3.0.101 version.
Developed specifically for Stock Rom.
Cpu boot at 1216 MHz.
Gpu boot at 384 MHz.
Undervolt.
Boot with 'pegasusq' as cpufreq governor.
Boot with 'sio' as block scheduler.
CPU overclock selectable up to 1460 MHz.
GPU overclock selectable up to 512 MHz.
Last ducati-m3.bin firmware included.
Without debug code.
SElinux Support.
Activated ZRAM with LZ4 compression
Tweaked Init process.
Android F2 File system (F2FS) support.
Union File system (AUFS) support.
Windows NTFS support.
Windows CIFS support.
Unix/Linux NFS support.
Windows exFAT support.
Apple HSFS and HSFS+ R/W support.
Manages /etc/init.d/ and /etc/sysctl.conf.
Init's improvements built in kernel.
Compiled with Linaro 4.7 toolchain.
I think it does not need further sysctl.conf tweaks.
GENERAL NOTES:
Booting pegasusq because it is very soft with frequency scaling and looks as good compromise between performance and battery saving.
User can insert boot actions by scripts in /etc/init.d. Here, it is important to establish execution's order, starting with numbers script names,
to run always the latter that has the largest number.
With this kernel, the user not need a separate script to run at the end of the boot.
Has been included an interface to the OC of the GPU, using "cat /sys/devices/system/cpu/cpu0/cpufreq/gpu_frequency"' command to view current frequency.
Kernel will stop secundary processor when its performance is not necessary for the functioning of the tablet.
The second processor still remain stopped with low power requirement, even the first reaches 600 MHz.
Reduced the working voltage used by the Core, GPU, and CPU frequencies up to 1216 MHz.
Completely replaced the memcopy & memmove functions code for memory data movement. The new code can be up to 10 times faster.
Releases for GT-P5100 and GT-P5110/3
Releases for Jelly Bean 4.1 and 4.2.
Go to Dowload
CHANGE OC OPTIONS BY HAND:
Code:
# GPUFREQ --> X = 1 (384 MHz) || 0 (307 MHz) || 2 (512 MHz)
echo 'X' > /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
# CPUFREQ --> X = 1216000 || 1008000 || 1360000 || 1420000 || 1460000
echo 'X' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
# SCHEDULER --> X = row || cfq || sio
echo 'X' > /sys/block/mmcblk0/queue/scheduler
# GOVERNOR --> X = pegasusq || lulzactive || interactive || hotplug
echo 'X' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

This rom? http://forum.xda-developers.com/showthread.php?t=2783989
No because I prefer android 4.1.2 . However the tab remains with the sentence: "Samsung Galaxy Tab 2 10.1". I feel the boot sound but the tab doesn't boot and remains the sentence "Samsung Galaxy Tab 2 10.1"
Just want to say this kernel makes my device a proper tab 2 with 4.2.2. No lag just smooth.. thanks OP!
@tuxafgmur, if you want I can test 4.1 kernels for you
@tuxafgmur, send me a link to download by pm when you will do the next version. I will test it.

Hi mate,.. tried to flash this on my stock 4.2.2,.. but flash failed,.. I think its something to do with the assert lines,. do I need to change / modify the Updater Script ?
If so, can you pls explain what is required

If your device is GT-P5100 then you must download p5100 file, else (your device is GT-P5110/GT-P5113) you must download P511x file.
I think that's your problem. Please, not change nor remove the assert lines.

Edit,.. Thnx Tux,.. all good now now,.. great work, !! I've been running Kitkat,. however I like the stock UI,. and now its OC'd its much smoother etc,..
cheers !
have anyone tried and tested on 4.1.2 ?
Hello,
I need some help please: the device (P5100 in my case) needs to be rooted and a new (modern) recovery installed or it works with stock recovery?
My TAB was previously updated to stock 4.2.2 (which I like it and used it for 5 months btw) without any other modification until now; and with your help, a little boost to it will be more than welcomed...

Thanks, however I'm trying your kernel with zap blaster 2.3 rom and it's fantastic , now I can use 4.2.2 well. Thanks for this fantastic kernel
Nice work indeed, thank you very much for a better kernel.
A little problem (on my P5100 at least): when using videos from youtube, after some suspend/resume/switching tasks, videos would lock up and wont play anymore, just black screen. I think it's because 900mV for 300MHz is not enough for my CPU. Is there a way to change that default boot frequency table to 950mV? I changed it with VoltageControl you mentioned above, and it seems it's working with the new settings, but I don't want to use an application at boot time, I just want to be the default 950mV for 300MHz. Where do I have to look?
sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table*is changed when modifyed with VoltageControl, but reseted always to 900mV after boot.
Thank you again.
I really like this kernel!
Makes my son's Tab2 faster and snappier.
Please dear @tuxafgmur have you considered to update it anymore? :fingers-crossed:
Thanks in advance mate

Kernel with diag mode
Hi, i have 5.1
This kernel has diag mode? Ty:good:
Is a sale for kcontrol app planned?
Or is there any way to enable sweep to sleep without an app?
Dear Bricked kernel Developer and Pro consumer
Excuse me. I am novice(beginner).
Q1.
when released next stable version?
(lastest stable version is 15/03/23)
Q2.
I use stock rom 5.1.1(LMY48B) & stock kernel after format.
I will use
LMY48B stock Rom and Bricked stable kernel(15/03/23)
This combination is good harmony(stable?) ? OR Wait next stable version??
Q3.
I love bricked kernel and KControl.
Because many smoothness and High performance.
I think that default settings are High performance and high temperature.
Did you recommend me between battery and performance balance settings?
I don't speak english well.
Excuse me.
Thank you for reading this thread.

I cann' t speak for @show-p1984 but here is what I think.
Q1. Next stable might be when android M gets released.
Q2. Yes it should work on 5.1.1. Do not try on android M as it won't work.
Q3. I use following settings
Low Freq 96 Mhz
High Freq 2265 Mhz
Governor Conservative
Touchboost On
Run queues to hot plug 15, 30, 40
Run queues to unplug, 10, 15, 25
Undervolted to 700mV
Get good performance and very good battery life.
Thank you very much.

Looking very nice mate, hope to see more tweaks, we have a beast of Exynos and with this new kernel could possibly get the most out of it, is there any key reason on why you compiled it with Linaro and not with Uber?.
Hi guys
you can be this version on the model H to Install??

I really cringe at the thought of even dignifying that with a response. Read the original post to avoid looking like a fool again.
Flashed it earlier today. The Kernel feels really good on Sweet ROM V10. I'm getting good battery on it (left my Note 4 alone for around 8 hours and came back with just 15% battery drain -- and that's with all these email accounts and so forth polling in the background) and it feels smooth the way V11 felt smooth to me.
I like Kernels and ROMs that Devs put together for themselves. They're usually pretty reliable as daily drivers. Great job!
Well , i run dr ketan rom and i leave my cell ag 100% for 5-6 hours and when I wake up is still at 100% ! Im happy with that

While the Dev's certainly free to do whatever he pleases, I hope he continues refining his U kernel
I think it's in poor taste to hijack someone's thread to ask for unrelated assistance -- DM'ing the Dev would have sufficed. The amount of effort would've been the same. By doing it publicly, you aren't really asking for help; you're asking for attention.
This is similar to that time a few people started spamming the Exynos threads asking for donations to a specific Note 4 CM12 project so that the Dev could buy a Note 4 and develop CM12 for ONE variant -- without ANY assurance whatsoever that it would be released for other variants. As we've all seen, there are enough differences between the variants that successfully developing for one doesn't mean being able to release a build that works with another.
In terms of levels -- this is just one rung above asking whether this kernel works on 910H or 910C. Not good form.
My main attention is the N910U as it's the device I own Time depending, I'm going to investigate sound mods and may offer a couple of versions based off of Linaro and UBER (when im more familiar with it). No ETAs
Kernel compiled with Linaro GCC 4.9.4-2015.06 Toolchain

Unpack and flash with Odin:
G386FXXUAOA1_G386FPRTAOD1_PRT 4.zip
Added: 20.12.2015
I decide to clean this post a bit. If You need only kernel, simply unpack it from G386FXXUAOA1_G386FPRTAOD1_PRT 4.zip
Hi Agasharr,
Overclock 1.46 GHz working fine with your G386FXXUAOA1_G386FPRTAOD1_PRT.zip !
What's next ?
Thanks !
Hi, in next kernel i'll add:
CPU Governor (userspace, smartassV2)
I/O Scheduler (sio, deadline)
Added:
smartassV2 had some issues (running always at max speed) and was removed
lulzactive seems to have same issue, it's still in kernel but i'll probably remove it

Nor am I. But i see no sense in including all of them. Mostly there are based on Ondemand, Conservative or Interactive (as described in link You provided). So it's a matter to choose the best of it's type and tweak the settings to our device.
@Agasharr I agree with you, I ignore which is the best for us. By the way, this list may be outdated since 2012, maybe some new governors exist now ? @benplay G386FXXUAOA1_G386FPRTAOD1_PRT 2.zip flashed OK today with odin 3.10.6 for my French G386F too.
New kernel uploaded, cpu overcloced to 1,612 MHz.
Added nightmare governor.
Phone is stable, but running few benchmarks makes it definitely warm.
Maybe it's time to make http://forum.xda-developers.com/optimus-4x-hd/general/guide-homemade-heatsink-easy-to-make-t2971385
Antutu score rises to ~18700.
As some kind of summary (the left side, in green, my g386f with the latest kernel, the right side is "average" g386f from Antutu database)
Hi Agasharr,
With overclock 1.612 GHz, I get Antutu score 19246 with ondemand governor.
I guess next step is upgrade to Android kitkat, isn't it ?
Thanks !
Hi stefguer.
I wish it could be possible. But seems that no one can hack secure boot of g386f.In fact it's reason I named this kernel "last hope".
Shame for secure boot. What is your next upgrade then ?
I've some ideas if they work I'll let You know. But don't expect anything soon. Especially with such enthusiastic feedback I'm getting now
btw. inspired by the http://forum.xda-developers.com/optimus-4x-hd/general/guide-homemade-heatsink-easy-to-make-t2971385
I decided to make something with this additional heat from overclocking, i used termopad to transfer heat to more areas, 1 mm thick is max that can fit, if someone would like to try something similar I advice 0,5 mm
You gave me hope one more time in the Galaxy Core LTE !
However I have some questions... I'm not pretty good about android and the developpement of it and after and afeter reading many tutoriels I don't succed in getting mu boot.img : so how do you made ?
Hoping one day my phone will be with Cyanogen ^^
Hi, You want to flash kernel?
If so download G386FXXUAOA1_G386FPRTAOD1_PRT 3.zip
from the first post, unpack and flash it with odin (tool to flash samsung's firmwares)
If You want to prepare own boot.img just to be sure it's safe. You need to download samsung firmware (same version that is in your G386F), and follow the procedure described in the opening post.

Nice ! Well, i think i won't try your kernel since my battery is not really in a good state and overclocking would make it worst, but do you think you could add OTG support in the kernel ? It seems the material and rom are OTG ready ('drivers' etc) but the kernel isn't
Suemax-kernel for N910C/H and N910U
CAUTION: I'm Not Responsible for any kind of Damage to your devise or Hard or Soft brick and even any damaged MicroSD-cards And now your devise warranty is Void and knox trip 0x1.
Note Read Carefully Before Flashing my kernel :
1) Keep the thread clean and try to research before e.g Google or wiki Before posting any further queries.
2) As mentioned Over-Clocking and Under-Clocking CPU or GPU is Not really healthy for Devise Hardware,So keep in mind its
Only an Option i'm providing due to its Got some limitations and might Damage soc in Extreme .
3) Under-Volting or Over-Volting CPU or Gpu to Extreme is not Helthy either And on Exynos 5433 soc it waries on scale
ASV-Group 0 to 15 (The higher the ASV, the higher frequencies your device can run and lower voltages).
4) And Ofcourse Need not to ask best settings (This term does not exist) for your devise e.g Undervolting etc And read
point 3 again . FYI : All users are different and So is devise Soc and there Usage + Usability of each User.
5) About Random-reboots are often Happens due to Unstable user Settings .So think twise before to apply any setting in
Snaypse app e.g CPU ,GPU or IO requires resrating Snaypse App or Even reqires a Rebooting devise to make apply proper
Setting like Under-Volting or IO scheduler.
6) No Asking ETAs and Special-demands .
7) Everything is detailed and explained in Synapse app for Most Users and All settings Values are Stock On first Boot.

Sorry Guys its too much work will edit OPs later and add screenshots and Update other details ASAP
Woow finaly!!! Tanks man!!
Gonna try this asap!!
Thank you^ ^
Lalalalalalalalalalalala
Always nice to see development coming across NOTE 4. Downloading as we speak.. test it out & will report.
Thanks for kernel & supporting NOTE 4 development.
THANKS FOR YOUR GREAT KERNEL
Can i turn off some a57 cores ?
I want control 2 core a57 and 4 core a53 running. Is it possible ?
Thanks
No V2 yet? I don't approve! Lol j/k, thanks for your kernel! <3
Going to try this out. Thanks OP!
Intitial Testing: It's fast. Almost the same as the kernel I used to use on 5.0.1. One thing though, could you add AUTO for HMP Migration? I think it sets itself to ON while on Power Save and Off automatically when PS is off.
Bug: Number of Cores running only works for 4 to 8. Turns out you can't turn off any small cores.
Edit: HMP Migration stays at OFF. If you reopen synapse it'll be off again if you turned it on.

Just read OPs
Thank you .!!!
@ArmsAsuncion
1) There No Bug and thats How hotplug works on Big core with 4 to 8 core option .
2) You the only user who have this issue with HMP migration and it just Work fine after even Reboot .
3) HOTplug on Little cores its not possible or nither any dev like mentioned in ops had tried .
4) You did not provide specific Details and Using Agressive Hotplug with HMP migration might not work .
Note : Stop irrelevant questions and read OPS + reasearch or troubleshoot before next Reporting .
Thanx
Well, not to be rude or anything but it's really not saving for me. It's fine though. Maybe something's off with my rom/synapse. I'm not asking irrelevant questions. Is HMP an irrelevant question? If you say so, then.. thanks for answering though.

its nothing about Rude at all .!!! Its simple Logic Most of the time its Userspace error and instead of checking reporting Nagative feed back false Bug is considered irrelevent And thats only reason I mentioned alot in OPs :good:
Whats hmp fork migration on big cores?

Its Load Shift + Balance (Generic)
Lol and its pretty clear in its term "hmp fork migration on big cores" Is Self-Define
I won't know if it was only me who gets the problem without asking first, right? Okay. I don't want to sound rude and will stop now.

Dear friend .!!! its not your fault but False alarming is not good for my thread :angel:
BTW : you see the screenshot i have posted after even reboot and there is no such issue at all for enable or disable. And Little details would help explaining your Issue as Mentioned And no point nagging on Developer with false bug report.
Cheers
Help Request: [P3110] Cm13 Android 6.0.1 Custom Kernel, Root & Test Review (Updated)
Greetings Everyone;
I've flashed "CM13 Android 6.0.1 (Marshmallow) [Unofficial]"
[Detailed Info]
Android Version: 6.0.1
CyanogenMod Version: 13.0-20160911-1524-Unofficial-expressowifi
Build Date: 11/09/2016
Build Number: cm_expressowifi-userdebug 6.0.1 MOB31e f5b160c161 test-keys
Kernel: 3.0.101-g34c045f
I'm Extremelly Happy with it.
So far i believe everything is working (almost) perfectly - Not much to point out so far.
The only things i can point out are:
- In some Wifi Networks, the Wifi won't get Stable (Works great at my own Network at Home, but Constatly Disconnects on My Job Network) - Yet I'm not 100% Sure if this issue is related to CM 13 6.0.1 ROM.
- Battery Consumption is above Normal (as expected, but I noticed that it consumes too much battery and that it will still discharge while charging.
I.e: While playing (i.e: Playing SimCity). However it will still it hold on for a Really Great Time While under Intensive use.
* Aprox. 3h ~ 4h (On Battery)
* Aprox. 4h ~ 6h (While Charging / Discharging)
Normal Usage: It works perfectly normal (specially great power saving while device is idle / standby).
Due to this Battery Consuption Issue and for Battery Saving / Overclock Purposes i've been looking (without success) for:
How to Root Android 6.0.x and a Custom Kernel that would let me Underclock (For Longlasting Battery) / (Overclock for Performance Purposes)
After some extensive search i could find this XDA Thread:
http://forum.xda-developers.com/galaxy-tab-2/galaxy-tab-2-unified/rom-cyanogenmod-13-cm13-0-t3303798
But as far as i understand it requires to be compiled; and i have no skills on how to do it (Never tried it to be honest).
Can anyone point me out on the Good Direction for:
- How to Root;
- Custom Kernel
Thanks in advance.
Best Regards;
Richard G.
Andi cm13 rom is perfect I'm using it and won't change it for anything else except the N rom.
If you are looking for for a good kernel to overclock or downclock this is the only one compatible with it with minor issues (the boot iui will turn 90 degree) http://forum.xda-developers.com/showthread.php?t=2183830
Other than that everything is fine...

Hello Zidane01;
Thanks for your prompt repply.
I believe i'm using Android-Andi's CM13 Rom (I really don't remember the website source).
However i updated the thread and included detailled information about it / what i am doing here.
I think other p3110 users without this ROM will apreciate the information above.
Did you manage to Root / Get Root Permissions with that ROM? (if so, How / Where? - Manually; with CF-Root; other method?)
Regarding the Kernel:
I Will give it a try, and write some more about it later.
I've been reading the Dhollmen Kerned Thread; the issue is known among other users as well. It will Most likely be fixed in the future (hopefully).
I don't know wich file you've flashed in your device; however according to the Thread:
Quoting (With Slightly Improved English and 1 Tip)
" If you're on Marshmallow then Flash Latest "DhollmenM Kernel" (Notice the Capital M); but i dont think it will boot up on new CM 13 Builds.
Important: DON'T Flash DhollmenCM as this is for Jellybean CM10!!!!! "
Further Info:
DhollmenL : Lollipop versions
DhollmenK : Kit-Kat versions

Hi. All Andi and Ziyan roms are already rooted . To get root access you have to go to settings then about my tablet go down to build number then keep hitting it until you get developers access now go back and in developer options go to root access change it from disabled to apps only or apps and adb if you are planning or know how to use adb
