1.1 Standard DRM Framework

Normally, A IVI system may include the three parts: HMI plane, Logo plane and RVC video plane. A cluster system may include the two parts: HMI planes and animation planes.

As shown in Figure 1-2, the standard framework, the Direct Rendering Manager (DRM) resides in kernel space, so user-space programs must use kernel system calls to request its services. A library called libdrm was created to facilitate the interface of user-space programs with the DRM subsystem. This library is merely a wrapper that provides a function written in C for every ioctl of the DRM API, as well as constants, structures and other helper elements.
