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 mpo-overview.rst dc-glossary.rst |
