# tuned-amdgpu
Hacky solution to integrate AMDGPU power control and overclocking in `tuned` with Ansible
Hacky solution to integrate AMDGPU power control and overclocking 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
_TLDR:_ See [my host_vars](./host_vars/localhost.yml) for an overview.
An attempt is made to discover the active GPU using the 'connected' state in the `DRM` subsystem, example:
A host will have a collection of `tuned` profiles.
For example: `desktop`, `balanced`, `virt-host`
*This* role extends *those* with AMD GPU power/clock/voltage control.
Each gets `default`, `overclock`, and `peak` variations.
An attempt is made to discover the active GPU using the 'connected' state
in the `DRM` subsystem, example:
```bash
~ $ grep -ls ^connected /sys/class/drm/*/status | grep -o card[0-9] | sort | uniq | sort -h | tail -1
card1
```
_Warning_: This is only tested with `RX6000` series GPUs, it is probable that other generations will *not* work properly. Use at your own risk!
