Nicholas Kazlauskas 98b070694f drm/amd/display: Fix max vstartup calculation for modes with borders ... [ Upstream commit d7940911fc ] [Why] Vertical and horizontal borders in timings are treated as increasing the active area - vblank and hblank actually shrink. Our input into DML does not include these borders so it incorrectly assumes it has more time than available for vstartup and tmdl calculations for some modes with borders. An example of such a timing would be 640x480@72Hz: h_total: 832 h_border_left: 8 h_addressable: 640 h_border_right: 8 h_front_porch: 16 h_sync_width: 40 v_total: 520 v_border_top: 8 v_addressable: 480 v_border_bottom: 8 v_front_porch: 1 v_sync_width: 3 pix_clk_100hz: 315000 [How] Include borders as part of destination vactive/hactive. This change DCN20+ so it has wide impact, but the destination vactive and hactive are only really used for vstartup calculation anyway. Most modes do not have vertical or horizontal borders.
