You can refer to below kernel repository, https://git.tizen.org/cgit/platform/kernel/linux-exynos.git/ branch name : tizen And there is no any change between ODROID-U3 and XU3 even XU4 so you can use odroidxu3_defconfig file for all of them.

ODROID-XU board is much different with U3, XU3 and XU4, especially 3D GPU so below kernel wouldn't support the ODROID-XU board. If you want to use our kernel for ODROID-XU board, you would need to port board specific part and some portion of Exynos5410 SoC maybe. So how about using one of other boards, ODROID-U3/XU3/XU4 which are supported by our kernel?

Linux framebuffer has the limitations not MIPS. Linux mainline had already stopped new feature update for Linux framebuffer, which means Linux mainline will move to DRM gradually. Actually, most ARM SoC started to move to DRM already. > > 2. Can you be a little more specific about bypassing the DRM and use Linux > framebuffer directly? Native window system is X and it uses DRM at the > backend. Before that, Could I ask you about why you want to bypass the DRM although you already has the native window system which provides the DRM backend? AFAIK, you can use X server with FB backend by building it with proper configuration - please, check X server build document. However, the problem is that you have to implement a buffer manager as a TBM (Tizen Buffer Manager) backend[1] because all X clients allocate DMA buffer through TBM[2] interfaces. If you use DRM, then DRM could be the backend. If not so - you use FB, then other buffer manager would be required for it such as ION[3] or other vendor specific one.

Also will check it but this way, using #if 0, is not good.

TBM and TDM backend are Tizen HAL modules dependent on Hardware and its kernel. So you would need to implement these HALs - TBM and TDM backends. You can refer to below porting guide. https://wiki.tizen.org/Tizen_3.0_Porting_Guide If your board uses mainline kernel which never include in-house code then you could use libtbm-dump and even libtdm-drm(by disabling ENABLE_PP config) packages below by installing them on your target. http://download.tizen.org/releases/milestone/tizen/4.0.m1/tizen-unified_20170529.1/repos/standard/packages/armv7l/ What hardware and Linux kernels are you using?
