From 0e190a0446ec517666dab4691b296a9b758e590f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Timur=20Krist=C3=B3f?= Date: Thu, 25 Sep 2025 20:45:25 +0200 Subject: [PATCH] drm/amd/display: Disable scaling on DCE6 for now MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Scaling doesn't work on DCE6 at the moment, the current register programming produces incorrect output when using fractional scaling (between 100-200%) on resolutions higher than 1080p. Disable it until we figure out how to program it properly.
