Hi, Thank you for your comment. On 2022/01/14 2:56, Bas Nieuwenhuizen wrote:
I think we'll also want to do a conditional disable for DC (drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c) since it only enables modifiers on newer HW. Something like "if (modifiers == NULL) fb_modifiers_not_supported = true;" in amdgpu_dm_plane_init.
Ok, I'll add a conditional disable in amdgpu_dm_plane_init(). Thanks, Tomohito Esaki
