From aed8b319180f18402ed90929f85e2b3e5b81e71d Mon Sep 17 00:00:00 2001 From: Shirish S Date: Thu, 8 Jun 2017 11:55:06 +0530 Subject: [PATCH] drm/amd/display: remove get_position() of underlay get_position() returns CRTC vertical/horizontal counters, hence it is not applicable for underlay which is plane and not attached to one crtc. This patch hence removes the callback from dce110_tg_v_funcs and hence fixes a bug in dc_debug.c where in get_position() for underlay pipe is called un-conditionally. Witout this patch get_position() is called in case one has to update underlay plane's data, since callback implmented with an ASSERT(), the old_surface_count and new_surface_count mismatches; causing only one plane update which is not right and also assert makes the rendering slow.
