Hi Shahul,
The answer depends on what you want and what you are ready.
If what you want to is just to "declare" that your hardware runs Tizen by showing Tizen menuscreen
and running some simple apps, as long as you have DRM support (with userspace support, libdrm),
touchscreen/mouse drivers ready, storage devices ready, and other drivers
normally considered already done with Vanilla kernels, it is usually "DONE".
However, if what you want is near-production-ready level,
ready for optimization & quality-control process (debugging!),
which implies that every peripheral hardware component is
ready and exposed to Tizen apps, you may have a lot more to do.
I usually do not expect the following device drivers for embedded
systems are ready in Vainlla kernels especially if the device componnents
are new: sound, WiFi/BT (often they just don't upstream or they
require special firmware), GPU (some vendors are already notorious in this matter),
video processors (they update too frequently just to be rely on mainline),
cameras (often you need proprietary binaries, so no support from Vanilla),
modem (usually proprietary firmware required), PMIC (if you've got new SoC,
you'll need new PMIC drivers, which means you'll need to write your own drivers),
and so on.
So, this heavily depends on how you define "I've done porting".
If it's the former, you are almost done (assuming you've already setup TIzen build system for MIPS).
If it's the latter, you may have a lot more to do depending on the readiness of your hardware platform.
(If there is already an Android support for your hardware, this becomes trivial as what you
really need is almost done by porting DRM.)
Cheers,
MyungJoo

Title : Re: [Dev] Tizen Bringup
Hi Myungjoo,
According to my observation usb framework and DRM(graphics) changes are there when compare to vinilla kernel and tizen 3.10.60 kernel.
Our is mips interaptive based platform.
By Adding DRM Related graphics driver and porting usb framework in our kernel, is sufficient to port tizen or i need to add anything else . Please help me.
Regards,
Sk shahul.

Hi,
Does your "ineda" platform boots up and runs X/Wayland with vanila kernel?
If so, then the answer depends on which peripheral hardware devices you want to support.
Cheers,
MyungJoo.

Title : [Dev] Tizen Bringup
Hi All,
I am planning to bring up tizenos on ineda platform. Can i use vanilla kernel directly or i need to modify kernel for tizen.
Please let me know kernel changes for tizen .
Thanks & Regards,
Sk shahul.
