| 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. |
