From c5a4f9010d4bcc4ea76341d7e5383b102f965ec5 Mon Sep 17 00:00:00 2001 From: Wenjing Liu Date: Tue, 25 Jul 2023 19:20:00 -0400 Subject: [PATCH] drm/amd/display: adjust visual confirm dpp height offset to be 1/240 of v addressable [why] For timing with large v addressable visual confirm is just too small. It is difficult to tell visually which DPP we are using. On the other hand with timing with small v addressable visual confirm is too large and covers the UI area. [how] We calculate visual confirm dpp height offset based on v addressable so it stays relatively the same height i.e. 1/240 verticle portion of the screen.
