tuned-amdgpu

hacky solution to integrate AMDGPU power profile control in tuned with Ansible

Notable variables

• power_max_multi: Accepts a float from (presumably) 0.0 to 1.0. Allows max GPU power consumption to be controlled. Default: 0.90 for 90%, roughly stock 3D peak.
• card: Sets the card# to use in the qualified sysfs path /sys/class/drm/{{ card }}/device/pp_power_profile_mode. Default: card0
• base_profiles: List of base tuned profiles to clone in the new AMDGPU profiles. Defaults:
  • desktop
  • network-latency
  • powersave
• amdgpu_profiles: Mapping of AMDGPU power profiles (name/value) defined in the sysfs path above. Varies, sample is with a 6900XT. Defaults:
  • { name: 'bootup_default', value: 0 }
  • { name: '3D_fullscreen', value: 1 }
  • { name: 'powersaving', value: 2 }
  • { name: 'video', value: 3 }
  • { name: 'VR', value: 4 }
  • { name: 'compute', value: 5 }
  • { name: 'custom', value: 6 }
