# configures GPU power/clock characteristics
# clocks/power in 3D are dynamic based on need/usage
#
# for 'amdgpu-default' tuned profiles, this will reset the characteristics to default
# for others this will apply overclocking settings -- leaving clock choices to the associated power profile (eg: VR)

# rendered by Ansible with environment-appropriate values:

# settings may need adjusted
