+===================================
+drm/amd/display - Display Core (DC)
+===================================
+
+AMD display engine is partially shared with other operating systems; for this
+reason, our Display Core Driver is divided into two pieces:
+
+1. **Display Core (DC)** contains the OS-agnostic components. 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:
