Hi Inki Dae, 1. Our SoC is MIPS based. Do the limitations still exist with Linux framebuffer?
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.

It's not compulsory but we recommend to use DRM instead of Linux framebuffer because Linux framebuffer not only has many limitations for advanced ARM SoC but also doesn't support the integrated buffer manager. > If not, what is the way to bypass DRM and use FrameBuffer directly to achieve > Rendering, and what are the advantages/disadvantages associated with the > same? > Please let me know. It would be dependent on what backend - Linux framebuffer or DRM - is used by native window system such as X or Wayland server. The advantages with DRM is that Tizen platform is DRM-friendly so it is easy to port Tizen platform to your kernel, including easy-to-manage DMA buffer and many hardware features available.
