tuned-amdgpu

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

Notable variables

  • power_max_custom_multi: Accepts a float from 0.0 to 1.0. Allows max GPU power consumption to be controlled in the generated custom GPU profile. Provided: 1.0 for 100% board power capability.
  • power_max_custom_multi: Accepts a float from 0.0 to 1.0. Allows max GPU power consumption to be controlled in the generated default GPU profile. Provided: 0.75 for 75% board power capability.
  • 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 (based on Fedora):
    • balanced
    • desktop
    • latency-performance
    • network-latency
    • network-throughput
    • powersave
    • virtual-host
  • amdgpu_profiles: Mapping of AMDGPU power profiles (name/value) defined in the sysfs path above. Varies, sample is with a 6900XT. Defaults:
    • { name: 'default', value: 0 }
    • { name: 'custom', value: 6 }

Example profiles/output
