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:
|
||||
- `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: '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: 'default', value: 0 }`
|
||||
- `{ name: 'custom', value: 6 }`
|
||||
|
