Official support from CyanogenMod Team for Galaxy W

i read something in the net while i was surfing yesterday, you can look here: http://www.androidcentral.com/motorola-atrix-hd-gets-official-cyanogenmod-support
and then reading these lines made me surprised(maybe getting official cyanogenmod support for ancora is impossible after this moment but who kowns?)
If an Android device has enough of a following, and there are developer(s) willing to commit (no pun intended) to maintaining the device in the official CyanogenMod source tree, this device becomes officially supported -- and receives official builds of the CyanogenMod ROM.
if someone be maintainer for our device can we get official support from CyanogenMod?
is this really possible?
ı mean our device source code are available in github(kernel source device source and vendor files)
maybe forking our device source into CyanogenMod source tree can make this possible or am ı wrong??
maybe this is a bulsh*it after this moment but just wondering
for example galaxy s is getting official support from Cyanogenmod still if im not mistaken mr. pawit is their maintainer and developer
ım waiting your answers brothers what do you think about that? @arco68 @arsradu @LeroViten @honeyx and all ancora devs
with my best regards :good:

The SGW was for more than 3 years without official CM support and we didn´t miss anything, so I don´t think this is that much important for the rest of it´s counted days.

ı understood bro but is there any hope for galaxy w? return of ancora :good: and also ı understood that from your comment : technically this is possible,galaxy w can get official support from CM Team but this is unnecessary for this dead device isnt it?

I simply don´t think this will happen because you have to look from their point of view.
1. this device is a low activity device in Amercian terms. 2. So never was that popular to get their attention. 3. is already old and not up to date. 4. It´s hype time is almost over and many earlier SGW users are going to replace it. 5. CM is going a different route now and will be focusing on their "device" they are going to launch soon. And finally 6. Why should they change this now after already 3 years?
So if I were CM I would look for the future not looking back to the past with it´s outdated devices and not even waste a single tought about devices like the SGW.
Is this bad for the SGW owners? As long we are having Devs like Radu who are porting the latest ROMs to this device it really doesn´t matter CM is supporting it officially or not supporting it.
So what do you expect from being supported by CM? You only would be able to install the latest nightlys launched by the CM team with all the bugs in the CM code included and maybe some day fixed. A Dev who is porting their CM sources of course has to fight with these bugs too, but also cares to fix the most important ones.

I asked arco68 a while ago, and he said it's because of legacy camera drivers that we are unsupported.

auhh thats true sir arne is right as always anyway thanx man for informing us
regards :good:

I don't think so...anyway, we already have the stable n smooth ROM so far. Without Officail, it's does not matter at all.

Hello sir @arco68
First of all huge thanx for your great work on our Wonders
And secondly i wonder something
We are using s5k4ecgx sensor for back camera
And if we add the following patches and if we use v4l2 for camera driver, Can we use CAF based qcom cameraHAL?
-http://www.spinics.net/lists/linux-media/msg50380.html
And probably if we use new qcom cameraHAL, then we wont need legacy stuff the CM doesnt like(MemoryHeapBase,Overlay)
Then maybe we can get cm nightlies
Maybe porting new camera Hal to our phone can be hard but we must not give up. We are so close to official CM after ION i think. We can do it and we can success :good:
Thanx
Regards

[Q] Compile kernel

I thought of developing a kernel so that i can use it with my CM11 that im going to port shortly. I thought I'll compile the stock kernel from source itself. I use android pre-built tool chain (arm-eabi-4.6)
I get a lot of compiler errors on stock kernel without any modifications itself...
Do i need to change my tool chain?
Sent from my One V using XDA Free mobile app

I never tried to build the stock kernel, but I think they did it with the android 4.0 toolchain.
To run CM, you need a CM-Kernel. You have to port things from the stock or a custom kernel (like Hellboy by maxwen) to the cm11 kernel.
Try to use rastomanchiks kernel sources (https://github.com/rastomanchik/android_kernel_htc_primou). This kernel is mostly working, stable and has a good battery life now.
I'd also like to build cm11, but my download speed is to slow to download the sources.

Exactly. Even my download speed is slow. And i have a cap also. After 8GB, my download speed drastically decreases. It takes ages to sync the sources...

How different is Cm kernel from stock? I mean what changes should i make?
Sent from my One V using XDA Free mobile app

Cm needs many features which aren't included in the stock kernel and also you should get ION memory allocator working.

I started working on cm12 again yesterday and finally have cm11 sources now, so expect a cm11 build in some days
I can't help you with porting, because all the porting work was done by rastomanchik and I chatted with him. You'd have to ask him about this, but he wasn't online the last weeks and can't speak english without google translator.

Actually I insist on porting myself so that I can learn building properly.
Actually these things are also interesting.. fixing bugs and all...
Have series of exams till May end. I cant build properly until then. I thought why not learn something..
Where did you learn about building and other stuff. Also I want to build the device tree on my own.
If you could specify some sources to learn, that would be grateful!

This is exactly the same point of view I had when I started some months ago
Sadly, there isn't much documentation about own device trees and own kernels out there.
There also is no reference device tree, so every dev does it in his own way. I'm always trying to have a clean, easy device tree and use the CM ones as a reference.
You can find some tutorials about building cm, but only with downloading a ready-to-use device config and kernel.
I just played around with it one or two weeks and learned the most.
If you have enough time, please at least try to get into this stuff, maybe we can get cm12 running.
You can reach me on irc in the channel #hov on freenode.

I have sufficient time only after May. Till then I'll have to do some research and learn the basics.
I saw on the CM wiki page, it says you can run a prebuilt kernel also... So would it work if we could tweak the stock kernel a bit?
And how do I apply patches to the kernel?

Yes you can use a prebuilt kernel, but it will only work if the kernel supports you cm version.
You apply patches to a kernel by changing files or directories in the kernel. For example you can use another fs module (maybe with more functions) by copy and pasting the folder for the module from another kernel. The problem is, the new module may require some functions your kernel does not have so it won't compile.

[DEV] CAF kernel 3.10.x

Hi guys, only few words:
I'm working on a 3.10 kernel just for fun, i dunno if i'm able to make it stable.
If someone want to help any help is appreciated!
it's based on LA.BF.2.1.2_rb1.5 CAF branch
source code is here branch LA.BF.2.1.2_rb1.5 and test_usb
test boot.img is here: http://www58.zippyshare.com/v/eqVBaQhc/file.html
Working list:
- it boots!
- touch screen
- backlight
- sms and call
- audio
- Bluetooth
- NFC
- 3D Graphics
- adb
everything else is not working. use it with a usb cable plugged in or it will not work.
Major issue atm: it doesn't work without usb plugged in.
thanks to @myfluxi for his caf kernel & ROM
thanks to @Sultanxda for some suggestions

That's a good news! Maybe @myfluxi can help?

Sultanxda said:
Stopped working on it :/ I managed to get modem firmware to load (modem still doesn't work), but 3.10 as a whole has one big problem on the Nexus 5: proprietary TrustZone (TZ) firmware. 3.10 is much, much more reliant on TZ than our 3.4 kernel. 3.10 is so reliant on TZ that the CAF 3.10 branch does not boot with the latest PM (power-management) drivers (I had to use the 3.10 source from the LG G Watch as a base to get this completely booting). There are scm calls to TZ everywhere in 3.10, and in particular all versions of 3.10's PM code are broken to some extreme degree with our ancient firmware (kernel always crashes on CPU idle power collapse). I'm sure it's possible to make everything work with our firmware, but you'd likely need to know things that only Qualcomm engineers know, such as the actual internals of the TZ firmware to see where there are incompatibilities between TZ and the new kernel (TZ firmware source code is confidential/proprietary, so it is not available to the public).

probably because now CAF source has got more patches than 1 year ago! maybe they used patches that already were in lg smartwatch source, who knows... luckily now we have got a booting CAF kernel

Bluetooth seems to work just fine.
3D Graphics work as well.
NFC works too.
(Not sure about hw video decoding & GPS)
Lots of SELinux denials though.

read from here to here, replace the kernel version in the url from 3.4 to 3.10 to get all improvements over the time. yes, backport features from 3.x/4.x to 3.4 will lower the gap between 3.4 and 3.10 but there's a motivation if newer devices use 3.10 instead backport stuff (caf will drop support for 3.4 sooner or later)

Hi. thx for your project. Maybe n5 users expect your 3.10.x kernel port even they can't write reply.
I test CM13-Caf 20160203.zip nightly with my girlfriend "D821 N5".
1.Rarely can't turn on lockscreen.(but screen was turned on)
-Maybe CM-Nightly's problem but no more happen after once happened.
2.Doesn't work 3g connetion
-I'm not use LTE,only 3g. Can't check LTE is working.
Before flashing kernel, network is working. Now Only work with UMTS. IMEI is fine. Network base is KT in South-Korea.
3.Wifi disconnect
-She don't recognize ip/mac address. Also can't find WIFI (2.4Ghz, 5Ghz)
4.Camera doesn't work.
-She have 3 eyes but only work 1 eye, Front Sensor.
Maybe you already know about it. I just nobody write about this problem in thread so I trying to write that problems.
Your 'Fun' gave us hope which n5 also have 3.10.x kernel. LOL

AS you know, even this project is awesome but unfortunatly it's only work in CAF rom.
So I have curious when this project is over, what will you choose your next activiation.
Get more project like Build AOSP+CAF rom, More fix to work in AOSP, continue fixing this kernel.... or have rest times!

i don't know where is the problem atm, i don't think it's related to USB drivers, sultanxda said it's TZ related... it isn't easy to track, i saved a log with something more than "watchdog bytes". also i don't know if LA.BF.2.1.2 is a good base, some drivers (ex adreno) are older than LA.BF.1.1.3 (our caf 3.4)!! xperiadev are working on LA.BF64.1.2.2 also for msm8974 soc, that branch is very up to date but i can't get it boot on hammerhead, and i don't know if they can get it boot on xperia devices with msm8974 soc...

Always try to build kernel with source. I think you can't, but you can try.

Please edit the link in OP, its me who miswrote it... : /android_device_xioami_mocha --> /android_device_xiaomi_mocha

You need to fix up SELinux and the init scripts. Taking a shield tablet device tree, renaming things to mocha and changing the fstab isn't enough. As far as I can tell the shieldtablet device tree also has dependency on a shield common tree. There's also no value in creating a new thread each time you push new commits
Our kernel from Xiaomi is also pretty useless without commit history. The device tree is also from shield tablet, not Nexus 9.
We also have a tree for building TWRP with OmniROM that you can compile TWRP 3.0.2.0 with.

What kernel repo is upstream one for tegra android? Like CAF for quallcom.
I've tried to merge xiaomi changes on l4t kernel https://github.com/HighwayStar/android_kernel_xiaomi_mocha
Merged dts files and arch/boot/march-tegra with some required drivers, but still cant boot it. Found somewhere here that l4t kernels is not for android, but for GNU/Linux, but what kernel is for android?
Cyanogenmod's shield kernel?

Untested, been doing device bring up. That kernel won't work yet anyway it's missing atmel, synaptic and battery firmware. (Plus the code that goes with it)
Some devs have one that gets to recovery but only 1 CPU core can come online and the CPU gets a bit hot. Unfortunately their commit history is hard to follow so I've not had a proper look at it yet

My my...it's been a while since I've seen a cringe-worthy dev thread on XDA. So OP just used the device tree from Nexus 9 (a 64-bit device with a different processor and nothing in common with the Mi Pad other than the fact that they use Nvidia SoCs and are both tablets), unmodified KITKAT kernel sources from Xiaomi (which takes work to make it boot, even on KK) and KITKAT userspace blobs to compile the ROM, and for some reason decided to share it without testing. The 10-post rule is meant to keep such people out of the development sub-forums, but obviously that's not working.
I do not understand why the moderators are allowing this thread to remain open. It's just a thread by a wannabe dev offering a non-bootable ROM that has the potential to brick the devices of many newbies who may decide to try this.
This thread is even more useless than the other "DEVS-ONLY" thread someone else made. Honestly, the entire Mi Pad forum is filled with people who either expect Android 7.1.1 to magically appear on their tabs just because Xiaomi released outdated kernel sources or just wanna create threads like this for the "thanks or whatever". The never ask for ETA rule seems to just float over their heads.
Now to some useful information. I believe, even if we patch the kernel enough for it to theoretically boot cm13, it probably won't, considering the outdated userspace blobs for the Mi Pad. Unless someone has the knowledge to take their tab apart and figure out how to get UART data, it will be virtually impossible for the mi pad kernel to boot any new version of Android. I heard another interesting approach taken by some russian devs at the Xiaomi forums. They've managed to port the kernel from the Nvidia shield (and apparently it's booting). Now this would mean we can use the userspace blobs from the Shield to at least get the ROM booting (most peripherals won't work, but that's step 2). I do not know whether they use GitHub or if they've even open-sourced their work, but now we know that it's possible, so that could be a possible method of approach.
EDIT: LOL. I just read the OP again. The "dev" expects donations to help him work harder. This from a person who posted his way into somehow compiling his first Android build without even having the damn device.

Unless someone has the knowledge to take their tab apart and figure out how to get UART data, it will be virtually impossible for the mi pad kernel to boot any new version of Android. I heard another interesting approach taken by some russian devs at the Xiaomi forums. They've managed to port the kernel from the Nvidia shield (and apparently it's booting). Now this would mean we can use the userspace blobs from the Shield to at least get the ROM booting (most peripherals won't work, but that's step 2). I do not know whether they use GitHub or if they've even open-sourced their work, but now we know that it's possible, so that could be a possible method of approach.
EDIT: LOL. I just read the OP again. The "dev" expects donations to help him work harder. This from a person who posted his way into somehow compiling his first Android build without even having the damn device.

I agree, this device has no development threads. Only 2 give me thanks and here's my donation link threads.
They have indeed used GitHub, but I don't believe they want to share the repo just yet so I won't post it publicly. It has many problems to sort and also sadly, they didn't keep the commit history from Nvidia as it was initialised via zip DL. It does boot to recovery though.

Oh! I didn't realize we were talking about the same person/team. I'd love to start developing for this device. In fact, I'm working on KEXEC-hardboot and Multirom right now, but I'd like to follow what you guys are doing and contribute as much as I can. Is there an IRC channel/IM app you guys use for communication? If so, I'd appreciate it if you could PM the info.

Older versions of LineageOS?

CyanogenMod was brilliant for old devices. You could take CM9, tweak it around, and install it on something like the Galaxy Ace GT-S5830. You could breathe life into an old device.
Will there be older versions of LineageOS to accomplish the same thing? For example, an Android 4.2 Jelly Bean LineageOS? Or will it go no lower than Nougat 7.1?

Any device that was actively being developed when CM ended should be picked up by Lineage OS. If the device was no longer supported by CM, it is not likely to be supported now.

It goes back to 6.0.1 but no further.

It will do both, apparently.....

Someone appears to have updated the cm-12.1 branch, FWIW. I'm wondering if they're slowly working backwards.

That would be my assumption since it's probably a lot easier to find people with knowledge to build CM13/12.1 than people with building knowledge for CM7 per say.

Funny you should say that, because I had to do just that very thing. I own an old phone (Motorola Atrix 4G) that never officially got support beyond CM7, so I've created my own custom CM7 for it (I'm using it as a glorified media player, but it's also allowed me to hone up on my Android ROM tinkering skills). When CM became LinOS, I created a Github organization (https://github.com/CM-Archive) to preserve the CM "gingerbread" branch, and found that there were a few things that need to be changed in order to make a clean compile. I'd offer to bring the "gingerbread" branch on LineageOS up to date for those few people who really need the CM7 code, as I've already done the work and know what needs to be changed, but as I've never made any contributions to CM or any ROM project, I don't know how to go about it. Can anyone tell me what I need to do? Something easy to follow, not "Get the frimfram and keloplotz the FTL missengibble on the gonfropple."

That's pretty epic dude! I have an LG Lucid vs840 from that had a CM9 out fot it was considering doing the same thing. As for helping them with their efforts I have no idea where to start.
But I do have a question, do you think it'd be very hard to update the cm7 cm9 or cm11 to Marshmallow devices? This might sound foolish but im still curious lol

The CM repo is moved wholesale to LineageOS, so if you know how to build, you could still build any version you like from the new source, provided that the older version was there previously in CM. I've built Lineage 13 (CM13) for several of my devices just now since I still need Xposed.
You can't expect any useful updates for <CM12.1 though, as CM had stopped working on them long ago. Not worth the extra effort of maintaining them, plus unfixable security holes.

Not looking to maintain them, simply to update them to compile from the LinOS repo. Specifically, the default.xml in the android package needs the references to CyanogenMod changed to LineageOS, and other references need to be changed as well. Once that's done, nothing further needs to be done.

You say that, but there was CM for my old 2011 LG phone but I would be tremendously surprised if a LOS ROM ever shows up because there doesn't seem to be any active development for that device anymore. Makes me sad because I would love to have LOS on it (and security updates newer than 2012) but I wouldn't bank on it... the newest CM ROM I can find for it is from 2015.
