We are using 3.10.5 Kernel which we have already used to bring up Android on our platform.
We have disabled the Android specific configurations and rebuilt it with TIzen_defconfig. We'll check the feasibility of using 3.14 kernel with SMACK enabled. We have DRM enabled but still need to integrate the PowerVR driver to it.
Our goal as of today is bring up Tizen 2.2 Mobile. We see that in repos, it is using 3.0 kernel.
We surely plan to contribute to the community. But it can take sometime as we still have to bring up our platform.
I cannot say on whether we maintain our platform specific patches ourselves or make them available through mainstream. That's management decision still pending.
On your suggestion, I have create a request on JIRA here: https://bugs.tizen.org/jira/browse/TC-1690.
I have tried to some local Tizen builds with Tizen 2.2 for armv7l and I am stuck with errors. I have posted that in a different thread: https://lists.tizen.org/pipermail/dev/2014-October/004390.html.
Please suggest on that as well.

This is something I care because I am trying to make Tizen:Common
supporting many different hardware
to make sure the system is not arch oriented and can be a solid base
for generic development...
Let me reference your project on this page I am drafting to ease cross
profile kernel packaging

Which version is it ? do you plan to share the source as community contrib ?
what about the targeted machine
Let me remind Tizen:Common requirements to be supported :
* need to have SMACK enabled
* need to be based on linux lts 3.14.+ (next ltsi?)
* need hw graphics (drm , egl...)

Yea I think this is the 1st thing to achieve,
do you indent to use obs/gbs or yocto ?
1st one is current tizen build system .

I dont see any easier way that bootstraping your own OBS server (using qemu)
or deploy it to a MIPS farm

I dont know any yet . but I know who can help you ,
So I invite you to report a "wish" tizen tracker and try to attract
ps: let's move the conversation to dev list ...
