-hacky solution to integrate AMDGPU power profile control in `tuned` with Ansible
+Hacky solution to integrate AMDGPU power profile control in `tuned` with Ansible
+
+Takes a list of existing `tuned` profiles and creates new ones based on them.  These new profiles include AMDGPU power/clock parameters
+
+## Profiles
+
+An example of the output/provided profiles follow
+
+| Output profile | Description |
+|---|---|
+| `balanced-amdgpu-default` | Includes the existing `balanced` tuned profile.  Only adjusts the GPU power limit (typically lower), clocks/voltage curve remain the default. |
+| `desktop-amdgpu-VR` | Includes the existing `desktop` tuned profile.  Adjusts the GPU power limit, clocks, and the voltage curve -- using the predefined `VR` profile in the driver |
+| `latency-performance-amdgpu-custom` | Includes the existing `latency-performance` tuned profile.  Adjusts the GPU power limit, clocks, and the voltage curve -- using the `custom` profile in the driver.  This opens up further tweaking through the driver (currently manual).  see: [pp-dpm](https://docs.kernel.org/gpu/amdgpu/thermal.html#pp-dpm) |
 
 ## Notable variables
  - Power control: (float) multipliers to determine power _limits_ from board power _capability_
    - `power_max_default_multi`: Controls power for the generated `default` GPU profile.  Provided: `0.75` for 75% board power capability.
    - `power_max_custom_multi`: Controls power for the generated `custom` GPU profile.  Provided: `1.0` for 100% 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`
+ - `gpu_mv_offset`: optional, applies offset to GPU voltage, eg: `+100` = to boost GPU core voltage `100mV` or `0.1V`. Can undervolt.
  - `base_profiles`: List of base tuned profiles to clone in the new AMDGPU profiles.  Defaults (based on `Fedora`):
    - `balanced`
    - `desktop`
