@ -34,9 +34,36 @@ Two _'profiles'_ are in each name:
|
|||
| `desktop-amdgpu-overclock` | Includes the (assumed) existing `desktop` tuned profile.<br/><br/>Adjusts the GPU power limit, clocks, _and_ the voltage curve. |
|
||||
| `desktop-amdgpu-peak` | Includes the (assumed) existing `desktop` tuned profile.<br/><br/>Same as the `overclock` profile, but locks clocks to their highest configured values |

## Notable variables
|
||||
## Config
|
||||
|
||||
These are the variables you're likely to want to change. They are defined in [playbook.yml](playbook.yml)
|
||||
The playbook will render this config file: `/etc/tuned/amdgpu-profile-vars.conf`
|
||||
|
||||
Here is a preview:
|
||||
|
||||
```shell
|
||||
gpu_clock_min=500
|
||||
gpu_clock_max=2715
|
||||
gpumem_clock_static=1075
|
||||
gpu_power_multi_def=0.869969040247678
|
||||
gpu_power_multi_oc=1.0
|
||||
gpu_mv_offset=+60
|
||||
```
|
||||
|
||||
Changes will require switching `tuned` profiles to re-read/apply the config.
|
||||
|
||||
One can use [gamemode](https://wiki.archlinux.org/title/Gamemode) to do this automatically on start/stop.
|
||||
|
||||
Sample `~/.config/gamemode.ini`:
|
||||
|
||||
```ini
|
||||
[custom]
|
||||
start=tuned-adm profile latency-performance-amdgpu-overclock
|
||||
end=tuned-adm profile latency-performance-amdgpu-default
|
||||
```
|

||||

|
|||
| gpumem_clock_static | Sets the _static_ memory clock for the GPU (in `MHz`). This is *not* the _effective_ data rate. That is a multiple of this depending on the type of VRAM.<br/><br/>To avoid flickering this does *not* change dynamically with load. |
|
||||
| gpu_mv_offset | GPU core voltage offset. Takes +/- some integer in millivolts. Can be used to both over _and_ under volt. eg: `-50` _(undervolt `50mV` or `0.05V`)_ |
|
||||
| base_profiles | List of base tuned profiles to clone in the new AMDGPU profiles. Defaults based on `Fedora` |
|
||||
| gpu_power_multi | Dictionary with two keys, `default` and `overclock`. Expects two floats to set a power limit relative to the board _capability_. Example: `1.0` is full board capability, `0.5` is 50%. |
|
||||
| gpu_power_multi_def | Float between `0.0` and `1.0`; controls power limit relative to the board _capability_. For _'default'_-named power profiles. |
|
||||
| gpu_power_multi_oc | Similar to `gpu_power_multi_def`, for _'overclock'_-named power profiles. |
