Actually we should update the cea_modedb in drm layer with 4k modes and appropriate VIC, coz the AVI infoframe functions are not getting proper VICs for cea modes. Or while processing alternative cea modes, we should check and return VICs.
I was planning to add 4k@60 modes, I will probably add one patch there, for handling the 4k modes in CEA db. As per CEA-861-F compliance, the 4k@30 and 4k@60 modes can come in cea DB as SVD modes. So we should have VICs for them also. We will also start upstreaming the patches we added for VLV/CHV, for handling aspect ratio support in libdrm layer as well as kernel.
