Documentation/gpu: Reorganize DC documentation

2021-12-13T21:33:16Z

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.

gpu: docs: amdgpu.rst: get rid of wrong kernel-doc markups

2020-10-28T17:42:02Z

As reported by kernel-doc: ./drivers/gpu/drm/amd/amdgpu/amdgpu_xgmi.c:1: warning: no structured comments found ./drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c:1: warning: no structured comments found Those files only contain /** * DOC: */ markups, but they're included twice there: one to parse such markup, and another one to parse internal functions. In the case of amdgpu_xgmi.c, as it has just one such markup, we can simply include the file once, and let it parse the entire file without passing arguments to kernel-doc. This should place everything altogether. For amdgpu_ras.c, however, we need to remove the kernel-doc with just internal. This should be re-introduced if this file ever gets new non-DOC markups.
