Official ICS + JB = ?

So I don't know much about Android development but since JB is supposedly pretty close to ICS, now that ICS is officially out, does this mean a JB with a working camera is possible? Or am I a dumbass?

I think people who assume and who dont actually ask questions are dumb... never think that of some1 who openly asks
Anything is possible, but doubt it cause as far as I know, simply adding drivers from ICS to a JB build isn't all that easy. Could be very wrong though

3.0 Kernel for AOSP JB?

I've been using Codename ever since it came out but I got tired of the problems related to the Kernel and switched to ProjectX. I and I'm sure others really want to use a smooth and working JB ROM.
Is there anyone working on the 3.0 Kernel for our device? I know Nik said he contacted someone to help us out but there's been no news on that front yet.
If anyone knows how to modify Kernels, Adi_pat gave some tips here -

He'll probably help us out if we make some progress in booting up Codename with it at least

Upon the exit of JB roms ago, were used GB modified kernel, now with source code maybe will be possible to compile a fully working kernel, but afaik there are no 3.x kernel for JB, maybe someone is working out of xda on irc channel but don't known..
Sadly I do not have much competence, plus I don't have the phone it's to repair....

There is kernel 3 for incredible 2 and desire s..may be someone can port it..

I might be crazy, but I remember reading a post not too long ago about a dev that was writing the 3.0 kernel from source for our phones. I haven't heard an update since then, but I remember hearing it was someone with relation to the cm9 team. It sounded promising, but that development was very slow.

Off the top of my head I seem to recall Noverbose saying he was trying to write a 3.0 Kernel. I also remember at least one other person mentioning something similar to, so there are people working on this. From what I understand it's not easy - I doubt we'll see anything this side of Christmas tbh. I hadn't realised that the Inc 2 and DS had a 3.0 Kernel though. Anyone know if they are actually a made from source version, rather than the same hacked version that we have in Codename, for example?

Well tbh honest a working GB kernel would do too.
Like the front camera and chrome and screen flickering etc.
Damn I wish kaijura was here

Yes those 3.0 kernels are compiled from source. I checked out AOSP ROM threads in the Desire S and Inc 2 section that had 3.0 kernel, then looked up the creator of the ROM on github and found the sources. I was going to try tackle the 3.0 kernel to get a hang of the make system before building CM9, but I don't have enough monthly data left to download the kernel toolchain! Nov 1st is close, so I can get to work soon! :highfive:
The best way to build an AOSP 3.0 kernel for our device would probably be to look at the source code for 3.0 kernels on our sister devices, and figure it out from there.

Well holy crap, dude, get on that! Seriously though, getting a working 3.0 kernel for our device would go a long way to making JB a usable ROM for our device. Would it be possible to port JellyTime or a similar JB ROM to our device as well?

The source doesn't need changing, it is the ramdisk that is the problem. I have been trying to get help, but so far no luck, adi_pat said he would take a look, but it is hard for me to test as I no longer have an inc s

I'm gonna worry mainly about compiling CM9 from source once November hits, that's gonna take up the majority of my time. After I get the first release of CM9 out, I'll start work on a 3.0 kernel if it hasn't been done yet. I have no experience whatsoever dealing with kernels though, except for small ramdisk edits, so don't expect any miracles.
It should be possible to port other JB ROM's over using one of nik's ported JB ROM's as a base and reference point, the only problem is I don't know exactly what files I have to substitute to port a ROM. I've PM'd nik about that a few hours ago, so hopefully I'll get some more information on the subject. Nik has been a big help to my dev efforts as a whole.

Interesting, if it's only the ramdisk that needs changing, couldn't you look at the ramdisk from one of niks JB ROM's? Or is it not as simple as that? I'm assuming the latter, seeing as if it were that obvious I'm sure someone would've done it by now. If you ever need help testing, send me a PM I'd be more than willing to test for you.

About using one of Nik's JB roms as a reference
What I understood was that the rom has been built around the old 2.6.x kernel and has to be modified again to work with the 3.0.x kernel, if you guys get one up and running. If that is the case, wouldn't you be going down the wrong path if you model it around nik's existing 2.6.x roms?
We need kaijura here, he was our AOSP kernel master. Hopefully he is doing ok, and has found something else other than xda because he hasn't been online for months. At least other devs, like lordclokan and kali- have moved on and are active with other devices... kaijura hasn't been on at all. Anyone been in contact with him/her?

I know, it would be going down a pretty redundant path. If I was able to port over a JB ROM using nik's ROM's as a base, then my ported ROM would inherit all the same bugs nik's ROM's already have.
I wish kaijura was still around, I have so many questions I want to ask about compiling from source! Luckily lordclokan was a massive help to me in that regard. Kaijura's github hasn't seen action in months either, sadly.

Forgive my ignorance, but isn't the Desire HD essentially our device with a bigger screen and less memory? That being the case, could we not just port across one of the 3.0 Kernels from that?

The problem with the ramdisk that come with the official ROM's that have 3.0 kernels, is that they are built for the sense framework and don't work on AOSP ROM's. The ram disk that is included with Nik's JB ROM's is heavily modified to run a GB kernel with ICS / JB sources, so the problem is I don't have a base to work from, I am basically trying to merge the two init's to make the 3.0 kernel boot.
Saying that we need to port 3.0 kernel is probably a bit misleading, and for that I apologise, the kernel itself has very little Sense specific stuff, it's the ramdisk that is responsible for launching the kernel that is the issue here at the moment.

The only problem with the desire HD kernel would be that our front camera would not work

Ok so 2.6.35 works with Jellybean. Why not pack the ramdisk with zImage compiled from 3.0.y sources(Considering you are using standard boot.img format[?]) Because to get it to boot, you would not require any hacks/changes to source, editing ramdisk(init.rc) is enough to make it boot initally.
EDIT: You may also need to change init binary.

honestly the guide is crappy and miss all the hardware dependent information and what needs to be modified to match current hardware and ANY framework change to support different functions.
OneX port was quite fine, but since telephony was rubbish and HTC made their own framework to support their own driver leaving out any support for other chipset, it is very hard to fix that one. except for that, i found the port quite stable except useless since phonecalls with GSM did not work

this is not related to a OneX port, it is just an app followed by a custom kernel to tweak performance, we got no kernel changes available (yet)

i know it can work with kholk's release, since i tried the 3.0 paranoid on his, but since extSD is no good, i will wait until we get something stable with custom kernel too.. too many halfbaked roms are no fun.

[Q] Can I get the Google edition?

Hi, Today the Google edition kernel became availble one htcdev.com

can I use this on my regular HTC One? if yes how can I do it?
Thank you

Roms will be out soon enough after a dump is given ...but for the time being we have kernel source so devs can implement Google's fixes into their Roms to make pretty much bugless roms

Hey, well we can get some pre-alpha 4.4 AOSP builds maybe, but these will definitely have bugs, i do believe adam has built a 4.4. omni rom but i don't know much about bugs/boot status etc.
We are still waiting for cyanogenmod to merge sources, however they have stated that they are in no rush to start dishing out 4.4 roms as they have only just sunken their teeth into 4.3 Roms, we will get them eventually, however any builds within the next few days will have little customization or lots of bugs, patience is all we have till then
I hope this answered your question, also, this needs to be in the Q&A section next time bro

Please understand that all the great things you've been hearing about android 4.4 wont apply to us for quite some time, what i mean by this is all the efficiency/ performance improvements will be somewhat mitigated buy bugs and firmware incompatibilities, these things take time for devs to work through, 4.3 still isnt mature enough on this device to call it stable.
I just don't want people to get overly excited by a 4.4 port, its improvements will come gradually.

4.4 sure is on its way for our device, BUT:
Google is removing more and more support for our device, as it already is pretty old. So we need to re-add everything.
Even if it's booting, we still need a lot of work in order to get the most important stuff working (like SurfaceFinger, Audio, and ofc also data/RIL)
So regarding 4.4, all I can say is: Have patience

Yes they are functionally stable to a user, but to call a rom stable (at least by Cyanogenmods standards) requires more than that.

Sometimes it's still necessary to do. This is the case with our EGL libs for example. The best would be getting an update from LG, but this is very unlikely to happen. I got 4.3 BSP partially working, updated all graphics-related libs to 4.3 from grouper, but it broke a few things. Porting the full BSP might not be even possible.
Regarding Omni 4.4, I gradually found probably all needed patches for it, will see when I get to computer.
