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,

|
|
|
1. Read frame information from memory;
|
|
|
|
|
2. Perform required transformation;
|
|
|
|
|
3. Send pixel data to sink devices.
