This thread is dedicated to disccuss and provide some general kernel information for our Xperia X1
This thread also added user's reviews and reports on the kernel what works and doesn't, so that we can choose our desire kernel based on our own need.
This thread is open to users' suggestion to help improving and adding more kernel informations and reports.
What is a Kernel ??
- Kernel is the foundation / base in which everything else builds upon in any software system.
- Kernel was separated into two files, one is named as modules-2.6.xx-xxxx.tar.gz and another one is named zImage
- Kernel control and effect lots of functions inside a ROM, like example: Wifi, tether, hardware key, speed, sound, charging, battery, camera, etc..
- [Car Analogy]: Kernel is like the Engine, Electrical system and the Transmission to a car. The Library, Framework and the Apps [AKA ROM] are the body frame and the rest of the Car.
- In conclusion, without a good kernel, there will never be a good Android build.

How many types of kernel we have for our X1 ?
- Until now we have two different source of kernel which are 2.6.27 and also 2.6.35
- 2.6.27 kernel was widely used by CWM users because it was more stable than 2.6.35 kernel AT THIS MOMENT
- 2.6.35 kernel was included in NAND version of X1 Android ROM (CM 7.1) which featuring faster speed and better performance, but with some little bugs AT THIS MOMENT

Any kernel developers here ??
- We have 4 kernel developers for our X1 Android development:
* Helicopter88 / Midnight: who was developing Midnight's kernel based on 2.6.27 with EXT3 system support
* ygge / Duckly: who had developed Turbo and Monster kernel (development had ended)
* sp3dev / Alex: who was developing kernel based on 2.6.35 and also developing the first ever NAND build for our X1
*Glemson: from XDAndroid Team who was compiling the XDAndroid kernel based on 2.6.27 source

What is the differences between these kernels ?
Since 2.6.35 kernel was not widely used for CWM build, I will only discuss and review 2.6.27 based kernel here
More information about 2.6.35 kernel can be found here: http://forum.xda-developers.com/showpost.php?p=16889651&postcount=39

How do I change a kernel ?
Changing a kernel is very simple IF you had follow all the steps provided by kernel developers. Remember to read the instructions or README in the kernel thread.
- For Midnight's kernel:
1. Delete old modules and zImage in npkboot folder
2. Copy the new modules-2.6.27.46-xx-xx.tar.gz and zImage from the kernel package to your npkboot folder
3. Compare this startup commands with your startup.txt, delete or change your commands if necessary:
Code:
set ramsize 0x10000000
set ramaddr 0x10000000
set mtype 2006
set KERNEL zImage
set INITRD_OFFSET 0xA00000
set initrd initrd.gz
set cmdline "rel_path=npkboot lcd.density=240 msmvkeyb_toggle=off physkeyboard=kovsq fbcon=rotate:2 ro.sf.hwrotation=180 msmts_calib=0x0366.0x04b.0x0c8.0x038e acpuclock.oc_freq_khz=652000"

- Be advise that if you are changing kernel from Turbo / Monster kernel to Midnight's kernel, your may experiencing Wifi error. The solution is format System and Cache partitions and then Wipe Dalvik Cache (You can do these in CWM menu)
- If formatting partitions and wiping Dalvik Cache does not solve the wifi issue, then you have to make a fresh install
- Even thought you had replaced the new kernel in npkboot folder, sometimes the kernel does not install into your build because your system thinks that it was the same kernel. This situation happens when you are updating Midnight's kernel because Midnight was improving the kernel based on the same source code 2.6.27.46
- You can see whether your new kernel had installed or not by looking on the linux boot screen after running Haret. After the boot screen had printed out 'Press volume down button shortly to launch CWM recovery', focus on the print out.
- If you see this line: installing /sdcard/npkboot/modules-2.6.27.46 (the modules name), means that your new kernel had installed successfully.
- But if you see this line: modules already unpacked for this kernel version -- skipping installation of /sdcard/modules-2.6.27.46 (the modules name), means that the new kernel does not installed to the build.
- I suggest you all to wipe Cache partition and Dalvik Cache each time after you had installed a new kernel to prevent some weird issue happens

More info about kernel needed:
1. Reports on Midnight's V9 kernel
2. Reports on ygge's Turbo and Monster kernel
3. Reports on XDAndroid's kernel
don't forget that midnight's and ygge's kernel are based on alex's one
i think sp3dev deserves more credits

Sure of course.. will add XDAndroid kernel + reports later.. thanks for reminding..
EDIT: Added XDAndroid's kernel and reviews.. more reviews needed from users.
hey dear friend for ur nice job.....
But one suggestion.....
I think this thread will be more complete to use as a reference if u add the fixes and the issues of each kernel.....
this way suppose that a user has a kernel related problem[e.g. battery indicator issue]and he wants to solve it, he can realized exactly what kernel he should replace and for sure what issue will be happen to him!!
think about it.....

yes, but you know that xdandroid kernel changes for xperia are mostly sp3dev commit's (the other 90% of commits on xdandroid kernel doesn't affect xperia in any way, they are mostly for rodium, topaz, and raphael), so there is just a bit of difference with his xperia cloned repository
btw, good luck for your great work! it's wonderful to see so many devs working on Xperia i noticed a new cloned repository but i didn't understood that was for xperia
I just replace my turbo kernel with Midnight's V9,I expect my battery indicator issue should go away....But the problem exist on my HoneyDroid .....any solutions??
Thanks so much jerrytan for this amazing topic ... I hope people help expand it ... I won't try cuz I don't fully understand how kernels work but this topic is great and I needed something like that to understand more about kernels ... as soon as I can understand enough, I'll do my best to report back and help ...
just one question ... It's my understanding now that Midnight's kernel has a perfect charging abilities and that it will work fine and u don't have to plug in the charger before booting Android ... right?
if that's right ... does that mean that ur HoneyDroid should be working fine with the charger and battery reading ... and can this kernel be used with SenseDroid to have these working?
Thanks so much for your efforts and sorry for the simple questions, but again I'm new here ... and I know this isn't an excuse but I tried reading but since I don't have much experience I don't understand man things

Yes Midnight's kernel fix the charging issue, and it should works well with HoneyDroid, even with other builds as well.
It's not a big problem for newbies as we all in this forum were also starting from a newbies to become a experienced member, all we need is to ASK and then LEARN.
Thread updated with latest Midnight's V10 kernel, V10 has more accurate battery reading than V9.
Now including some little guides for you all to install a new kernel..
Thanks so much for the detailed explanation ... that helps a lot
and thanks for being patient and answering my questions ... I'm learning already ...
well, I'll use ur description and I'll do a clean install with your SenseDroid V9 and midnight's V10 Kernel and report back on what I find as soon as I can ... I can't code or make roms, so I'll do my best with the testing ... Do you think trying Midnight's kernel with an EXT3 Rom like HoneyDroid would be better than with an EXT2 Rom or is it about the same ???
Just Another small questions ... would Midnight's V10 Kernel give also that warning when the battery is low that Turbo's kernel gives with SenseDroid ... and how accurate is the battery reading ... is it close to the one with Turbo's??? and is there a way to import the accurate battery reading from Turbo's Kernel to Midnight's ?? I'm sorry again if these questions don't make sense and btw, I mean an easy way that a newbie can do ... Thanks so much for the help again

main advantage of ext3 over ext2 is journaling which improves reliability and eliminates the need to check the file system after an unclean shutdown, this will give you a more stable system.
for my experience with ext3, I get a super fast ROM installation in CWM, almost twice the installation speed than ext2, the boot time was only 30 seconds after the boot animation displayed.
I haven fully test Midnight's V10, I just can confirm that the battery reading works but don't know how accurate it can be. For kernel development you can ask Midnight aka Helicopter88 to get more information.
I will update ALL of my xDroid series builds in this week so that all of my builds supports EXT3 format system which will give your more enjoyment with my builds. so STAY TUNED for more updates..
Hello, this is my review of Midnight V10 Kernel in Jerrytan SenseDroid V9 ROM
*No more keyfreeze. (The most important item I think)
*Charging is fully working in Android.
*Good Battery Life. (At least with V9, didn't tryed V10 so long yet.)
*So far, answering calls is working good. (No need to turn speaker On/Off)
I think this is the best kernel right now. It solves the big serious issues, like keyfreeze and battery charging and reading.
Thank you all!
Thanks so much man ... That's sounds great ... I can't wait to try an EXT3 SenseDroid ... that sounds good ... I just love that Rom
well, I've just did a clean installation of Midnight's V10 Kernel with SenseDroid and it looks good so far
The only problem I have so far is that I can't seem to get the wifi to work and I did turn it on in winmo before booting into Android ... any tips on that?
Also, there is a weird voice that comes from the speaker ... I think this is the hizzing u r talking about ... I still hear it
That noise was annoying me ... so, I'm gonna reflash a rom using Turbo and wait for you to make the SenseDroid EXT3 version to test Midnight's kernel ... but I have to give it for Midnight for his amazing kernel ... other than that hizzing noise and wifi ... it's an amazing kernel ... fast, great, light and does the job

tnx dear friend for ur feedback......BTW do u experience the speaker noises??
No, I didn't.
Some users says the noice start when the internet 3G conection is active, but no in my case.
Also, wifi is working perfect in this rom.
After whole day usage, I noticed that V9 & V10, has high battery usage, comparing with SenseDroid default kernel.
And sometimes, when the phone is charging, the battery percentage just jump around...
Btw, I just have one question, if I use a battery meter or calibration tool as a standalone app from the market ... would that solve the problem with the battery meter or will it stay since it's kernel related not rom related?
Also, After more observation ... The hizzing sound in V9 and V10 is like people said happens when you are you using 3G/GPRS (internet mobile) in general and if there is no data transfer, the hizzing stops ... so, it only happens when the network is being used ...
something that confuses me ... before the phone detects the network and it says no service but internet mobile is working fine ... the hizzing doesn't happen but after I fix it and the phone detects the network ... it happens ...
I hope I have helped ... I tried Midnight's V9 with HoneyDroid EXT3 Rom and it works but when I tried V10 I had no wifi working, so I switched back to V9 again ... and there is no hizzing btw ... so, the hissing was only there with V9 and V10 when it was used with an EXT2 Rom which is SenseDroid ... but no hissing with EXT3 and V9 ... it only happens with V10 ... so, waiting for Midnight's answer on the hizzing sound

the battery indicator issue is kernel related and it will not be solved with standalone app or widget....
I don't use Internet and I hear the noise[I mean if I get my ear close to phone]
It's doesn't so important to me,Just it coz battery drain....

Fastest kernel I used!
3400 quadrant, without overclock! Very snappy
Hi,
I'm coming from MCR fr17 Fear Kill edition 10.. it is using the 2.6.32.8 kernel.
My questions are as per below (Sorry I'm new to android devices and trying my best to learn):
a) When flashing a new kernel, I just put it in my SD card and flash it in recovery correct? Or do I need to perform a wipe before doing so? Need to clear any cache etc?
b) For those that have tested this kernel, care to upload the stable voltage for 1000 mhz, 1200mhz and 1300mhz?
c) What if I undervolted it so much that it isnt a stable voltage? Will my phone be a brick?
Thanks to all that take the time to guide a noob like me.

In Pimp my CPU, use the stress test to see if its stable. Use the settings without saving it so you dont boot with those settings. But just to make sure, make a backup of the rom if absolute everything f*cks up.
Sent from my LG-P990 using Tapatalk
Currently I cant even run a CPU Stress Test. When I do, the application will be forced closed.
Do take note that I havent flashed in this new kernel yet.. Using 2.6.32.8 atm
I flashed this Kernel with Stock ROM, but I found that my existing Pimp my CPU not work anymore. Please suggest use with version is fine, Thanks.
Same, this kernel doesn't support PimpCPU I believe. Nevertheless, it's the most stable kernel that I've tried so far...
What advantages are their of converting to ext4? Looking for a good kernel current running modaco fr17 will this be ok?

I'm actually not looking for an OC, I was looking for a UV.
Sorry if it is a noobish question but wat advantage does this bring over stock kernel?
Sent from my LG-P990 using Tapatalk
This kernel provides ext4 support. And a small fix I believe. So the advantage is a general speed improvement with phone usage.
Guys, my O2X just got updated (via LG PC Suite) to v10d. I already rooted it, but can anyone confirm if this kernel still works with it?

I am facing touch screen problem when ever I install CyanogenMod (not happening with Stock Rom) my touch screen has become over responsive.
As i press any key (or not) the phone detects key press. It is mostly happening in lower left (where * key is present)

cyanogenmod 7.2 or 7.1 ?
right now, i am using ics final (cm 7.2) and the touch is working fine
i faced similar issues before though. dont know if it helps, but go to /system/etc/init.d
and there maybe some scripts and tweaks. try to remove them and see.

Please explain in detail as i am a newbie
i also have the same problem, esp. when i flashed a new kernel its has become more over responsive which gives me a headache
try flashing another custom rom?

i am not sure what the solution is, but u can try once.
use root explorer (or similar file manager)
go to /system/etc/init.d
now usually (if no tweaks and scripts are enabled) there will be some files.. like 00banner,01sysctl....20userinit
if there are any other files after 20userinit, delete them.
then reboot. see if its any better.

so, how do you fix the sensitivity issue? i am also having the issue which is really annoying.
To all:
I'm 99% percent sure the problems you guys face are because of the OC kernel in the CM. Can you try flashing a non-OC kernel and determine whether the results differ?
In my case with non-OC kernel the problem still occurs. The only solution is underclock processor to 735MHz. Any ideas?
edit:
connect phone to the charger solve the problem too ;X WTF? even if i overclock to 850MHz, touchscreen works perfectly!

Lolz. You must be kidding.
All : Even i am facing same issue after flashing Gingercrutz (only 2.3),ICS SUNDAY and Infinity rom. Still no solution for that.
Touchscreen Problem Fix
i had the same problem of multiple touches...b'coz of over sensitivity while using cm7.2 with oc kernel.
after flashing a non oc kernel either from ketut's or an0nym0us u can fix the prob.
thats how i fixed it.
Note:- Don't compare ur processor with other's(thinking other's can do oc without ny prob but not mine ..) b'coz every processor is different in some sense.
That's why some of them oc to even 960MHz and remain stable while some can't even take 820MHz(no wonder i belong to this category )
k so here u go :
ketut's thread :http://forum.xda-developers.com/showthread.php?t=1296905
cm-7.1-kernel-2.6.35.7-perf-CL562111.zip:download and flash this kernel using cwm (rem to mount system b4 flashing)

zImage-Mod.v1.0.zip : flash this using cwm (mount system b4 flashing)
Note:- v1.1 is also thr but v1.0 is more stable (can find out in thread)
Plz press thanks if I have helped
I no longer know what to do. Non-oc kernel help a liittle but not completely solve the problem. Still helps me only underclock MHz to 735.

i had the same problem of multiple touches...b'coz of over sensitivity while using cm7.2 with oc kernel.
after flashing a non oc kernel either from ketut's or an0nym0us u can fix the prob.
thats how i fixed it.
Note:- Don't compare ur processor with other's(thinking other's can do oc without ny prob but not mine ..) b'coz every processor is different in some sense.
That's why some of them oc to even 960MHz and remain stable while some can't even take 820MHz(no wonder i belong to this category )
k so here u go :

Before you do anything: This is purely at your own risk and I will not be responsible for anything that happens to your tablet. I flashed it on mine at my own risk.
Compatibility Information: There are 2 different versions. 1 for stock and 1 for Cyanogenmod. Even though the kernels are intended for the 3G tablet it will work just fine on a WiFi only tablet (like mine). This makes the build process less messy.
**Sources Fully documented v1.9 beginner friendly sources now available including the build script. If more explanations are required, please say so. However, remember that the explanations are not intended to be a blind step by step instructions of going from samsung source to A1.
TWRP V2.6.0.0: Please read: do not worry about any kind of "E:A: Render Error". This is a side effect of removing some image files to save place on the recovery image so it will fit on the 5MB. The error simply means it failed to show (render) and image file that it is looking for. This is not harmful at all. If you can't flash the recovery please try the dd method.
V2.6.0.0 3G Download
V2.6.0.0 Wifi Download
V2.5.0.0 3G Download
V2.5.0.0 Wifi Download
TWRP V2.6.3.0: There are no more E:A Render errors. All graphics that were removed are there. Also, the recovery will install supersu if no root is detected. That feature has also been restored. The kernel has been stripped of anything not recovery related to shrink it down. It also has selinux support which allows the "set_metadata" zip installation to work. The download is in the attachments below.

Great to see someone else kernel developing, could be the start of something here... Lol, I wanna give this a try but I think It'll stop 3G working if I flash the 7510 kernel.

Care to try the 3G version I just uploaded? I don't own the 3G version but I followed the same idea for compiling the 3G kernel.
Welcome, nice of you to come to the party
Is there really no one that can test and leave test reports? If i would have been on sammy rom i`d been all over this.
Good luck dev

Voodoo works perfectly.
It can even overclock the CPU to make and perfect kernel.

Overclocking abilities is quite a tall order for my current "skills". After looking at the instructions on how you would do it, the process looks much much more involving than just a manual patch job. Weird thing is that after an initial read through of the instructions it looks like a 1.2Ghz overclock code is in the kernel source but I'm not sure why it's not turned on.

I was quite surprised to discover that the charger that comes in the box of the galaxy tab 10.1 actually sends some kind of "green light" to the tablet to begin charging. If the tablet gets the box charger it actually records "samsung charge !!!r" before activating the charging. If any other charger is connected the tablet records "invalid charger !!!" and disables charging in the next line of code. I just changed it so that it will record "other charger" in stead of invalid and enable charging after recording. (yes, the original code had those exclamation marks after charger).

You mean the task650 one? Of course it is! That's the only stock ics rom I've ever flashed on my tablet. I credited task650 in my first post for providing a clean deodexed rom to test on.

From the nandroid backup you make before flashing anything.
I don't think a package has been made yet for ICS boot.img.
hey guys ,, i have finished all my work on viperx but im having difficulties for finding a suitable kernel to use without getting big battery drain ,,please select wisely ONLY according to battery life :angel:
I just tried Noobys kernel apart from stock one, I sometimes get excelent battery life, using almost 5hours of wifi, like 48 hours, but some days i cant get through the day, I think is related to my installed apps..
I wish i had tried more kernels to help you decide which one to use in your ROM, because im actually using Nemesis 2, but happens that i find both (rom+kernel) very stable for everyday use, and want to keep it like that.

IMO, The most important thing to chose a kernel is first it should stable, then good battery life. For include in your ROM I suggest you use the kernel that stable for everyone. As you know, every device has it own limitation, how high it can handle the clock, how low it can handle the voltage.
Why?
Some user dont know what custom kernel is, and what the advantages and disadvantages if using custom kernel. Some user usually flash and use the ROM as it is. If they flash the ROM and the ROM doesnt stable for them, mostlikely they will say something like "The ROM is not stable, I got SOD" or "This ROM is sucks, often reboot by itself". Yes, they will blame the ROM, whereas actually it because their device cant handle the UV or OC kernel.
Also you can write suggestion to use custom kernel to gain more battery life/performance in your ROM's thread.
The users can easily to flash other kernel that they like after they flash the ROM.
Well, this is just my thought. The decisions is up to you
----------------
as for the poll, I choose ZGK v0.1-beta, coz:
- 200/500/700/1000/1100 (OC not too high so it save, 200 as min clock good battery in deep sleep)
- stock voltage (no SOD)
- stable for my old P970, and battery drain is good enough

Well, the title says it all, what do you think is the best rom + kernel combo when you're talking about battery life. (4.3 or 4.4)
SOKP 4.4.4 , F2FS Formatted + Art enabled + AGNi kernel with 60mv undervolting and battsave profile , i can get two days easily, no perf loss , i get ~20000 in Antutu , 22000 with oc @ 1700mhz and performance mode

Hey man, first i flashed SOKP and directly after that the AGNI anyrom aroma 2.8.1 kernel but first the aroma installer didn't work right and after i finally installed the kernel i had a bootloop, you know what to do about this problem or is a boeffla kernel maybe a better alternative?
The actual AGNi got a bootloop problem , take this one , the 2.8.0 is the last working one : PSN_pureCM_11_ANYROM-AROMA-v2.8.0_I9305_OC-signed.zip
and forgive the f2fs idea , to do a format it's plenty of **** , none of the recoveries work (excepted the one twrp made by psndna) some kernels are uncompatible , only activate ART, choose the battsave profile in AGNI kernel manager and get the cpu undervolt to -50 mv (if you're having issues , only go to -40 )

Hi. Currently under Slimkat 4.4.4 for approx one week. I last a bit more than two days, with no specific optimization. The best match for me so far.

These kinds of threads are against the rules. It is offensive to developers to start comparing and criticising other ROMs (whether you realise you're doing it or not).
If you were clever, you'd start a "what kind of battery life do you get from your installed ROM?" thread. This is within the rules, not prompting comparisons, but would yield useful information as people show their battery stats, kernel settings and installed ROM... then you can choose yourself.
Or you could just download some ROM's and test them yourself... What works best for others may not work best for you due to differences in how you use the device.
Thread closed as its a Best ROM/Kernel thread.
