SGTM, you mean amdgpu/index.rst, right? Yeah, but I'm also thinking about this new organization: 1. Create an amdgpu folder. 2. Inside amdgpu folder, I want to create a display folder. 3. Move all display documentation to the display folder and keep other amdgpu generic things under amdgpu. 4. Finally, inside the amdgpu folder, I'll create the index.rst for amdgpu, and inside the display folder, I will create a similar

Seconded, I think when driver docs get too big for the single file approach a directory matching the driver name sounds best. Also at that point maybe just drop the amdgpu prefix in the .rst files, it's kinda redundant? -Daniel > > Regards, > Christian. > > Am 25.11.21 um 16:38 schrieb Rodrigo Siqueira: > > Display core documentation is not well organized, and it is hard to find > > information due to the lack of sections.

Re: [PATCH 1/6] Documentation/gpu: Reorganize DC documentation
Just a general comment. Could you name the new subdirectory "amdgpu" instead? DC is just a component of the amdgpu driver and I think it would sooner or later make sense to group together the amdgpu documentation in one folder. Regards, Christian.
