The goal of having this section was to ease the learning curve but the way I worded it may reinforce the perception that DRM is hard to learn. > IMHO we could add a separate section that talks about complexity and > provides guidelines about how to deal with it: trivial HW? use simple > pipe; dedicated VRAM? try TTM; awkward color formats? see > drm_format_helper.c > Indeed. And we can add such section as a follow-up. Maybe referring to some of the drivers in drivers/gpu/drm/tiny. Best regards, -- Javier Martinez Canillas Linux Engineering Red Hat
