From 7a7e7bcefdd3e44c58ee17e81f36308ca7aecdb7 Mon Sep 17 00:00:00 2001 From: Alex Hung Date: Wed, 4 Feb 2026 22:05:16 -0700 Subject: [PATCH] drm/amd/display: Remove conditional for shaper 3DLUT power-on [ Upstream commit 1b38a87b8f8020e8ef4563e7752a64182b5a39b9 ] [Why] Shaper programming has high chance to fail on first time after power-on or reboot. This can be verified by running IGT's kms_colorop. [How] Always power on the shaper and 3DLUT before programming by removing the debug flag of low power mode.
