-===================================
-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 RAS Support
-==================
-
-The AMDGPU RAS interfaces are exposed via sysfs (for informational queries) and
-debugfs (for error injection).

-
-Sample Code
------------
-Sample code for testing error injection can be found here:
-https://cgit.freedesktop.org/mesa/drm/tree/tests/amdgpu/ras_tests.c
-
-This is part of the libdrm amdgpu unit tests which cover several areas of the GPU.
-There are four sets of tests:
-
-RAS Basic Test
-
-The test verifies the RAS feature enabled status and makes sure the necessary sysfs and debugfs files
-are present.
-
-RAS Query Test
-
-This test checks the RAS availability and enablement status for each supported IP block as well as
-the error counts.
-
-RAS Inject Test
-
-This test injects errors for each IP.
-
-RAS Disable Test
-
-This test tests disabling of RAS features for each IP block.
