[DEV][C2105][Kernel][TWRP]Compiling Sony Kernel Sources for Kitkat

I am very interested in porting Xperia L to OmniRom and had starting work on it. The kitkat sources is already available anyway(see here). Compiling it is easy, just follow the instructions. I now have a working kitkat rom which unfortunately seem to have a serious bug of unable to go into deep sleep(dropped >40% over a night).
I have started work on the kernel sources and wish to invite all developers who are interested to work together.
For those of you with wifi issue, make sure that you are on stock rom 15.3.A.x.x
Extracted from Sony opensource
Most of the AOSP for Xperia L device configurations are cloned from the official Xperia L software version 15.3.A.0.x, so please make sure that you upgrade the phone software to, for example 15.3.A.0.26, before flashing the AOSP for Xperia L images, or certain functions like WiFi may not work.
Known issues/workaround:
1. There are some missing KLOG information that prevent building of the kernel( fix by disabling CCI_KLOG)
2. Deep sleep issue seem to be caused by wait_for_irsc_completion timeout(workaround by disabling
MSM_IPC_ROUTER_SECURITY)
3. Enable reboot recovery
Sources
Kernel 3.4 from Sony
Github version by me

Have not worked with CAF kernel before. Moreover, the most important thing now is to get a stable working kernel for kitkat before embarking on anything else.
I will update my progress here in this thread. Its good to keep the communication open here so that others can also contribute/help. Right now, I can successfully compiled the zImage. Going to test it out later on.
update: notice that you have the 15.3.A.1.14 sources. Where did you get it from? My phone was running on this build before I flashed the AOSP 4.4 rom. Dont you have the CCI_KLOG compilation error on 15.3.A.1.14?

I got playing with kit kat for few days and when the phone try to go in deep sleep there is QSEECOM errors that stopped the freezing...
Im not a pro dev,so I might be wrong.

Which ROM did you test from? I just flashed the one I compiled from source last night so did not get to test much. What I did noticed was that the battery dropped >40% overnight. I suspect that it might not have gone into deep sleep.

@KillerKink getting the zimage is easy you will have to make certain changes to kernel/ramdisk to make it compatible to KK

This is not an issue for me. What I would like to know is where did you get the A.1.14 sources from? Dont you have compilation errors from the sony sources

I guess. 14 sources aren't published by Sony yet right? At least I couldn't find it.. Where did you get that from?

Wonderful. Did you manage to compile from sony sources with the sa77_defconfig without any change?
I had to disable CCI_KLOG.

Cool! Did the kernel have deep sleep issue？ Do you have git for your work?
How did you resolved the CCI_KLOG compilation errors?

Ye it have that issue, I saw that QSEECOM error on it. And sorry,I don't know how to use git and don't have kernel uploaded there.I'm using this as kernel base and don't have compiling errors.

Count me in for help. BTW I just saw your screenshot in OP in which you've booted kernel successfully on AOSP, can you link me to that kernel source which you used? I would really like to investigate on it.

feel free to work on it. The sources is the same one that I posted in the first post. btw it seem that there are many working kernels around. Guess I will work on porting Philz Touch recovery first.

this one proves that sony is looking after our device
and keeping updated
my experience says that we will receive 4.4 direct we may miss 4.3
as you can see many devices has missed 4.2.2 and got 4.3 direct
so when z family hits 4.4 we will be very close to have the same

No, it doesn't as they ignore us and doesn't fix fatal bugs. Don't be so ignorant...
If Mediatek doesn't bring kitkat or 4.3 to our SoC Sony can't do anything about it you know. And I'm sorry to say this but I don't think we will ever see a 4.4 or 4.3 update unfortunately.

It because sony give us xperia c with bootloader can't be unlocked, so we can't do anything.. Only Sony or Mediatek can solve this problem, or maybe they don't care about this device

I think we will probably get KITKAT!!! There are more chances of kitkat than 4.3 as AOSP sources of KIKAT have been alredy released by sony....

Come on brothers !!!! If Xperia M has got Android 4.3 it means our device will get 4.3 or higher(most likely) .
And remember Sony has us in AOSP project so KitKat sources are already ready , just wait till all Sony devices start getting 4.4 ,in that very timeline we will get ours, bcoz it doesn't make sense updating a mid-range device before flagships. (ZL, ZR,Zetc).
But also I don't think that you know , XM was updated before us so , even we may get ours before flagships

Firstly, the good news is there is an update coming for Xperia L which seems to be a bug fixing update. 15.3.a.1.1.6
It hopefully will be last try from the Sony to clear bugs from the current stock ROM.
Xperia M was announced in May2013 compared to March 2013 for Xperia L.
Usually a mid-range device receives updates for a year from Sony so it seems unlikely we might be pushed to 4.4.
If Xperia L KitKat was coming, they wouldn't release buggy premature source for Kitkat. The source code is always released after the ROM has been completed and is sent out to devices !
Doing that, they not only kept many people quite to show how friendly Sony is to developers but in the mean time, it bought them time so they can come up with an excuse later that 'a year of spupport' has been given!
I am sorry to disappoint you and I hope I am wrong, but a KitKat update seems very unlikely especially with their new devices being released so naturally they would be looking to discontinue support for many others!

KitKat is much better , and we r no kids with that mentality, and bro no one downgrades quality in an incremental update get ur brain right and if u know KitKat has new drivers so most problems get solved!!!

Talking about all this is waste of time!!! And be content as there is no big change from 4.2.2 so Sony doesn't probably want to waste development time for Android 4.3 , remember 4.2.2 UI was first seen on Xperia L , before SP , M ,V,T etc.
So we can even think a higher version is already in development

Xperia L will get Android 4.4 Kitkat update directly..
In May 2014, Xperia Z series will get 4.4 update, after that Xperia SP and after that Xperia L..

Lol I don't think so. I doubt it'll be 4.3, just maybe 4.4 but I really can't say. Like Hnk1 said, it's '1 year period' is over. It would be surprising if there's another major update, but i wouldn't expect it. All I can ask for is that the '1.16' update clears out all the bugs for us.

Update
Xperia M recive android 4.3 and more expensive Xperia L not !

[Q] kitkat for us?

I know this is a really common question and answer to this can only be given by sony ppl but still...
Are we gonna get kitkat update?
It really sux that we have "locked bootloader" + no "4.4"
If any one has any idea aboyt 4.4 plz keep posted...

Xperia E1 is scheduled for 4.4 but not Xperia C???
C mosts almost 2 times than E1!!! :silly:

Maybe..
I think maybe we can suggest a CyanogenMod version ...
Can't we?

It won't happen, Mediatek aren't planning to make sources for Mtk6589 for 4.4.

Nope... For that unlocked bootloader is required (because need to flash custom kernel)

(Q) Xperia L 4.4

Will our Xperia L get a Stock 4.4?
I saw a thread that someone is Porting xperia m 4.3 to our device How about
Android 4.4

No one knows, but propably no. Both Xperia L and M are mid-end devices, so official support is worser. I think Xperia L will get 4.3 (like XM).

Its logical that XL should get 4.4 but its at the same time very unlikely too.
We, the XL users are eagerly waiting for CM11 to come.

I think we will get 4.4 , because Sony made AOSP for XPERIA L

Internal Storage has a workaround on the two most used kernel for XL (Thunderzap and Phantom), and bluetooth has a solution to, but we need to wait the CM11 last build to see if the fix has a final solution.
