Subject: [PATCH] drm/amdgpu: Enable SMU 13.0.0 optimizations when ROCm is active (v2)
From: Kun Liu <Kun.Liu2@xxxxxxx>
When ROCm is active enable additional SMU 13.0.0 optimizations.
This reuses the unused powersave profile on PMFW.
v2: move to the swsmu code since we need both bits active in
the workload mask.
