Subject: [PATCH] amdgpu/pm: Disallow managing power profiles on SRIOV for Sienna Cichlid
Date: Mon, 9 May 2022 13:47:22 +0200 [thread overview]
Message-ID: <20220509114722.124060-1-danijel.slivka@amd.com> (raw)
Managing power profiles mode is not allowed in SRIOV mode for Sienna Cichlid.
This patch is adjusting the "pp_power_profile_mode" and
"power_dpm_force_performance_level" accordingly.
