Hi all, This block #if defined(CONFIG_DRM_AMD_DC) else if (amdgpu_device_has_dc_support(adev)) amdgpu_device_ip_block_add(adev, &dm_ip_block); #else # warning "Enable CONFIG_DRM_AMD_DC for display support on SOC15." #endif in soc15_set_ip_blocks() should probably be ported to a runtime drm_warn() no? This means a kernel with no DC support will just silently fail to light up on SOC15. I can write a patch for this if nobody objects. (found this while trying to sort out the PP get_clocks call for my Raven1 ...). Tom
