[Dev] [SDK/Emulator] The emulator, emulator-kernel upgrade notice.

As the emulator kernel had been upgraded to 3.12.x, do you think it is still necessary to use build_x86_ivi.sh to build IVI kernel respectively? Can we use build_x86.sh for all platforms? If not, will a special build script be supplied for Tizen Common?

After I re-cloned "emulator-kernel", I found that there was a script, build_x86_ivi.sh, in the project.
Currently, the emulator kernel for IVI is installed in ~/tizen-sdk/platforms/ivi-3.0/emulator-resources/kernel/bzImage. While, the default emulator kernel is ~/tizen-sdk/tools/emulator/data/kernel/bzImage.
Since the kernel image is platform-related, will there be more proper folders to place the bzImage for both in SDK? Or, should we distinguish them by file name in the default folder? As we also need to support mobile feature in Tizen IVI SDK by default.

There're problems with qemu 2.0 and Tizen IVI, they started to happen after the merge. I've tried only on Windows XP + Sandy bridge for now.
Steps to reproduce:
1. Launch Tizen IVI image
2. Open terminal
3. Type "dialer"
4. It will startup really slow and "hrtimer: interrupt took 182612036 ns" will be outputed very slowly into kernel log 5. Close dialer - qemu will crash
I couldn't get the backtrace, gdb says stack is corrupted, I could only see 1 function - ig4icd32.dll!DrvCopyContext this indicates that the crash **may be** related to OpenGL, but there were no graphics stack changes after the merge. What is also strange - if you switch to thread #1 in gdb you'll see that "WSACleanup" function is being called, but WSACleanup supposed to be called only on application shutdown, so why is it being called in the middle of operation ? Did anyone else experienced problems after qemu merge ?
