Things like 9e91f8401SRodrigo Siqueira hardware programming and resource management are handled here. 10e91f8401SRodrigo Siqueira2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the 11e91f8401SRodrigo Siqueira amdgpu base driver and DRM are implemented here. 12e91f8401SRodrigo Siqueira 13522968aeSRodrigo SiqueiraThe display pipe is responsible for "scanning out" a rendered frame from the 14522968aeSRodrigo SiqueiraGPU memory (also called VRAM, FrameBuffer, etc.) to a display. In other words, 15522968aeSRodrigo Siqueirait would: 16e91f8401SRodrigo Siqueira 17522968aeSRodrigo Siqueira1. Read frame information from memory; 18522968aeSRodrigo Siqueira2. Perform required transformation; 19522968aeSRodrigo Siqueira3. Send pixel data to sink devices. 20e91f8401SRodrigo Siqueira 21522968aeSRodrigo SiqueiraIf you want to learn more about our driver details, take a look at the below 22522968aeSRodrigo Siqueiratable of content: 23e91f8401SRodrigo Siqueira 24e91f8401SRodrigo Siqueira.. toctree:: 25e91f8401SRodrigo Siqueira 26e91f8401SRodrigo Siqueira display-manager.rst 27e91f8401SRodrigo Siqueira dc-debug.rst 28522968aeSRodrigo Siqueira dcn-overview.rst 29*a723c6d0SRodrigo Siqueira dc-glossary.rst 30
