From 1caba4e83b9d8a322375de04d2cfe23d7ccc1b89 Mon Sep 17 00:00:00 2001 From: Aric Cyr Date: Fri, 6 Sep 2019 16:24:54 -0400 Subject: [PATCH] drm/amd/display: Update V_UPDATE whenever VSTARTUP changes [Why] If VSTARTUP changes due to bandwidth requirements, we must recalculate and update VLINE2 as well for proper flip reporting. [How] After all calls to program_global_sync which reconfigures VSTARTUP, also make sure to update V_UPDATE (i.e. VLINE2 on DCNx).
