An example of the output/provided profiles follow
| Output profile | Description |
|---|---|
| `balanced-amdgpu-default` | Includes the (assumed) existing `balanced` tuned profile.<br/>Only adjusts the GPU power limit (typically lower). Clocks/voltage curve remain the default. |
| `desktop-amdgpu-VR` | Includes the (assumed) existing `desktop` tuned profile.<br/>Adjusts the GPU power limit, clocks, _and_ the voltage curve.<br/>Uses the predefined `VR` profile in the driver. See `/sys/class/drm/card*/device/pp_power_profile_mode` |
| `latency-performance-amdgpu-custom` | Includes the existing `latency-performance` tuned profile.<br/>Like the existing GPU profiles (eg: _VR)), this also adjusts the GPU power limit, clocks, _and_ the voltage curve.<br/>This differs by using the `custom` profile in the driver. This opens up further tweaking of the power/clock heuristics through the driver (currently manual). see: [pp-dpm](https://docs.kernel.org/gpu/amdgpu/thermal.html#pp-dpm) |

`amdgpu_profiles`: Mapping of AMDGPU power profiles (`name`/`value`) defined in the `sysfs` path above. Varies, sample is with a 6900XT. Defaults below
- `amdgpu_profiles`: Dictionary mapping the AMDGPU power profiles found in `/sys/class/drm/card*/device/pp_power_profile_mode`.
- Allows adjustment to the automatic power/clock handling in the GPU using either predefined profiles or `custom`
- More may be added, only three GPU power profiles are provided:
- default
- VR
- custom
- May vary by GPU/generation, sample (defaults, below) are from a 6900XT:
