- ===================================
- drm/amd/display - Display Core (DC)
- ===================================
- *placeholder - general description of supported platforms, what dc is, etc.*
- Because it is partially shared with other operating systems, the Display Core
- Driver is divided in 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.
- It doesn't help that the entire package is frequently referred to as DC. But
- with the context in mind, it should be clear.
- When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
- supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
- Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
- To determine if DC is loaded, search dmesg for the following entry:
- ``Display Core initialized with <version number here>``
- AMDgpu Display Manager
