# 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 }`
