[STICKY] Xperia X1 Kernel Development + Reviews + Guides [17/1/12]

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
More information about NAND build can be found here: http://forum.xda-developers.com/showthread.php?t=1329379

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

Wrong,mine's based on xdandroid kernel.
Jerrytan,pheraps you should add XDANDROID kernels in the list,since mine's heavily based on it(For heavily I mean 99%)

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.....
regards.........

Thanks for your suggestion.. but I need the reports from you all for help me testing all the kernels.
Users can send me their report for specified kernel by PM me. Any helps from you all are greatly appreciated..

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

so that means battery indicator still not perfect yet, but I think Midnight is working on that anyway..

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....

Overclock

Hi ,
I have a few begineers questions , I have a galaxy s that is running gingerbread 2.3.6 , is rooted and had a voodoo kernel (with recovery option) . I was thinking of possibilities of overclocking , can that be done with the setup I have ?
thanks in advance

You can easily overclock your phone with a root access with an application like this :
bit.ly/fnUFCD
There are lots of applications existing.
You can see on your kernel thread on this board what frequency is supported.

try Tegrak overclock or NSTools. Find other apps on Market.

thanks for the info guys , installed busybox and android overclock , but appears the kernel is not able to be overclocked as I got a message and the max frequency showing is 1000 mhz , would anyone be able to recommend a kernel that would suit - would like to keep things preety simple and straightforward at the mo
cheers

Semaphore is the best http://forum.xda-developers.com/showthread.php?t=1112908

thanks again , my phone is showing jvz suffix at end of kernel - show the semaphore jvz is the way to go ?
I am trying to avoid an expensive paperwight

Semaphore kernel can work on all gingerbread roms. So it is safe to flash semaphore 2.5 on your phone.

Will overclocking the phone significantly reduce battery life? Or cause any degradation of the phone due to excess heat?

Battery use will obviously be higher with the processor on more clock speed but there's no problem with the temperature. Remember, always overclock in minor steps,check stability and in this way you would get a stable phone

[KERNEL][CM10] CM10 kernel for ICS bootloader (RAM hack,OC)

This kernel is no longer being updated. Please refer to kowalski kernel thread for CM10 ROMs.
Presenting CM10 kernel built from source with ramhack and OC/UV support by wkpark
Only for the new (unlocked ICS) bootloader!
This is RC's kernel, with patches by wkpark for ramhack and OC/UV. Supports OC upto 1.5 GHz.
Thanks to them for all their work. Also, thanks to pengus77 for bringing CM10 to the new bootloader
Built using my guide over here
Uses spica's HP supersonic toolchain
Works with CM10/MIUIv4 ROM on new bootloader only
Download links:
New and recommended powersaver version!
Includes pengus77's wifi drain fix (All credit to him for that)
Non-OC, to increase battery life and stability
RAM hack values 24 MB, 32 MB, 48 MB for increased smoothness
New experimental governors are absent in this ROM, which is meant to be a stable version for daily usage. The new governors have not been properly tested yet and are unlikely to be used by most of the users. They may be included in later builds after more testing. If you want to use them, flash the experimental kernel on the previous page.
This is the version recommended for daily usage. Try the 48 MB one first, and if camera gives problems, then try a lower RH value.
Download link for stable, powersaver version
Link to latest experimental version
Download link for older experimental versions
This is the link to my folder with all kernels for the new bootloader so far, in case you want to try some other version. Ramhack values are mentioned in the file names, and if it supports OC (not every phone will like OC) it is also mentioned in the file name.
Thanks to RC and wkpark, this would not be possible without them.
Warning:
I am not responsible if anything goes wrong with your phone.
If your phone does not like OC/UV, or freezes when overclocked, reduce the max frequency or dont use the OC version of the kernel.
If apps like camera give problem, try to use a version with reduced ramhack value.
To be flashed over the ROM without wiping data. Wipe only cache and dalvik cache
If you are having problems with the new kernel and wish to revert back to the stock kernel, flash your ROM again
Credits:
arcee and the rest of the CM team. Its their work it is based on
Donate to RC
wkpark for cracking the bootloader, new his patches, without which, there would be no ramhack or OC/UV
Donate to wkpark
pengus77 for bringing CM10 to the new bootloader and wifi battery drain fix.
This wouldn't be possible without him
spica1234 for his wonderful HP Supersonic toolchain
benee for his anykernel updater for star, and for all his work
Other devs for all their work (PM me if I forgot someone!)
Source: https://github.com/rugglez

Changelog:
29/12/12:
New version built with spica's supersonic HP toolchain
Integrated pengus77's latest (v3) wifi drain fix + bsod fix
27/12/12:
Experimental version released with new CPU governors (smartass v2 and hotplug), and simple I/O scheduler (default is still cfq), max frequency=1.2 GHz
Power saver version released without OC or new governors, and with pengus77's wifi battery drain fix
26/12/12:
Initial release
Max clock frequency is 1.5 GHz

Trying the 32mb oc kernel, seems ok so far, will report back any oddities,
I'm on penguss cm10.

i tested..............

Great news. Just two little questions:
- does this work with cm10.1 as well?
- are the Wifi drain patches from pengus77 included?
Regards,
Orgler

Thank u guy's! i will try new_CM10_kernel_1225_32M_OC.zip and report back!

You could try it with cm10.1 but im not sure if it would work. Take a backup first. Wifi drain patches will be included with his permission and when he feels it is the right time (after the testing phase and all)

thanks for the hard work i think u can put like a changelog in thread and the features of kernel listed just avoid people asking same thinks all the time

included wireless.ko is the one patched by pengus? thank you in advance
edit: just checked, it's not the patched one

First impressions are good! Not much room for UV as 1ghz is already at 1000mV which is quite low already I think? But that is not important, just an observation.
Thanks Rugglez. Been waiting a while for an OC kernel on CM10 and no call bug either. This is the future for our phone I think.

I ´m testing the 48M_OC-Kernel on CM10.
I set max OC to 1,2GHz, but Antutu CPU Master shows Peaks at 1,5GHz! The Kernel is always scaling in its full available Range.
I tested it with different Settings and Gouvenours, nothing helps.

I just checked with "CPU spy" and yes it is hitting 1.5Ghz even though I have it set lower than that.

Noted. Will release 1.2 GHz and 1.4 GHz versions separately from next time
With pengus77 permission now, i'll integrate his wifi drain fix too.
Probably tomorrow

Same here oc set to 1.2 but it's scaling up to 1.5 seems stable anyway.
Took one pic and gallery FCed and phone soft rebooted.
With OC 32mb kernel camera and video recording is working.

I do a OC with default cm10 function and on antutu say 1200!

Sorry for being off topic. I really salute new generation of developers for optimus2x who never let us feel our main devs/modders have left. You guys are doing a fabulous job. Thanks to you all.

Gps does not working.

Please add pulse boost and hotplug governor. Thanks.

best kernel for ice boom v 1.1 (based V30B)

hi everybody.
I've a very deep question: what is the best kernel which I can use on V30B for improve battery life?
thx

I'm not sure what you are asking, titel of your thread don't really fits what you write.
If you ask for a kernel for IceBOOM from rrgrrg as he said in his fist post http://forum.xda-developers.com/showpost.php?p=35225392&postcount=1 the kernel from Gawbeakz (V30i Kernel). I don't think there is a other kernel as the one it came with, GB kernels will surly not run with it and ICS kernels probably neather.

Grazie Pado (thx Pado), but I've found some battery drain problems. BTW I flashed ZG rom yesterday evening and it is very fast and smooth. I'm really surprised by the work done from Andoiib, hence I will keep that ROM untill new Zeus (if it will be better than this one)
thx

[poll] what is the best kernel for the official ics ?

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
