2 drm/amd/display - Display Core (DC)
3 ===================================
5 *placeholder - general description of supported platforms, what dc is, etc.*
7 Because it is partially shared with other operating systems, the Display Core
8 Driver is divided in two pieces.
10 1. **Display Core (DC)** contains the OS-agnostic components. Things like
11 hardware programming and resource management are handled here.
12 2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
13 amdgpu base driver and DRM are implemented here.
15 It doesn't help that the entire package is frequently referred to as DC. But
16 with the context in mind, it should be clear.
18 When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
19 supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
20 Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.
22 To determine if DC is loaded, search dmesg for the following entry:
24 ``Display Core initialized with <version number here>``
