From 5cccf10f652122a17b40df9d672ccf2ed69cd82f Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 27 May 2025 10:13:31 -0400 Subject: drm/amdgpu: disable workload profile switching when OD is enabled Users have reported that they have to reduce the level of undervolting to acheive stability when dynamic workload profiles are enabled on GC 10.3.x. Disable dynamic workload profiles if the user has enabled OD.
