Things like + hardware programming and resource management are handled here. +2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the + amdgpu base driver and DRM are implemented here. + +The display pipe is responsible for "scanning out" a rendered frame from the +GPU memory (also called VRAM, FrameBuffer, etc.) to a display. In other words, +it would: + +1. Read frame information from memory; +2. Perform required transformation; +3. Send pixel data to sink devices. + +If you want to learn more about our driver details, take a look at the below +table of content: + +.. toctree:: + + display-manager.rst + dc-debug.rst + dcn-overview.rst + dc-glossary.rst |
