4 drm/amd/display - Display Core (DC)
5 ===================================
7 AMD display engine is partially shared with other operating systems; for this
8 reason, our Display Core Driver is divided into two pieces:
10 1. **Display Core (DC)** contains the OS-agnostic components. Things like
11 hardware programming and resource management are handled here.
12 2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
13 amdgpu base driver and DRM are implemented here.
15 The display pipe is responsible for "scanning out" a rendered frame from the
16 GPU memory (also called VRAM, FrameBuffer, etc.) to a display. In other words,
19 1. Read frame information from memory;
20 2. Perform required transformation;
21 3. Send pixel data to sink devices.
