Display core documentation is not well organized, and it is hard to find information due to the lack of sections. This commit reorganizes the documentation layout, and it is preparation work for future changes. Changes since V1: - Christian: Group amdgpu documentation together. - Daniel: Drop redundant amdgpu prefix. - Jani: Create index pages. - Yann: Mirror display folder in the documentation.

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:
