0004 drm/amd/display - Display Core (DC)
0005 ===================================
0006
0007 AMD display engine is partially shared with other operating systems; for this
0008 reason, our Display Core Driver is divided into two pieces:
0009
0010 1. **Display Core (DC)** contains the OS-agnostic components. Things like
0011 hardware programming and resource management are handled here.
0012 2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
0013 amdgpu base driver and DRM are implemented here.
0014
0015 The display pipe is responsible for "scanning out" a rendered frame from the
0016 GPU memory (also called VRAM, FrameBuffer, etc.) to a display. In other words,
0017 it would:
0018
0019 1. Read frame information from memory;
0020 2. Perform required transformation;
0021 3. Send pixel data to sink devices.
