# tuned-amdgpu
2021-10-18 22:31:35 +00:00
hacky solution to integrate AMDGPU power profile control in `tuned` with Ansible
## Notable variables
2022-06-08 00:33:23 +00:00
- `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`

2022-06-08 00:33:23 +00:00
- `virtual-host`
2021-10-18 22:35:11 +00:00
- `amdgpu_profiles` : Mapping of AMDGPU power profiles (`name`/`value`) defined in the `sysfs` path above. Varies, sample is with a 6900XT. Defaults:
2022-06-08 00:33:23 +00:00
- `{ name: 'default', value: 0 }`
2021-10-18 22:35:11 +00:00
- `{ name: 'custom', value: 6 }`
