# amdgpu_stats
A simple Python module/TUI _(using [Textual](https://textual.textualize.io/))_ that shows AMD GPU statistics
A simple Python module/TUI for AMD GPU statistics
![Screenshot of main screen](https://raw.githubusercontent.com/joshlay/amdgpu_stats/master/screens/main.png "Main screen")
The GPU and temperature nodes (`edge`/`junction`/etc.) are discovered automatically.
Please see [the module section](#module) or [the docs](https://amdgpu-stats.readthedocs.io/en/latest/) for information on usage as an `import` in other tooling
Supported GPUs and temperature nodes (`edge`/`junction`/etc.) are discovered automatically.
Tested _only_ on `RX6000` series cards; APUs and more _may_ be supported. Please file an issue if finding incompatibility!
## Requirements
Only `Linux` is supported. Information is _completely_ sourced from interfaces in `sysfs`.
It _may_ be necessary to update the `amdgpu.ppfeaturemask` parameter to enable metrics.
This is assumed present for *control* over the elements being monitored. Untested without.
See [this Arch Wiki entry](https://wiki.archlinux.org/title/AMDGPU#Boot_parameter) for context.
## Installation / Usage
## Installation
```
pip install amdgpu-stats
```
Once installed, run `amdgpu-stats` in your terminal of choice
To use the _TUI_, run `amdgpu-stats` in your terminal of choice. For the _module_, see below!
## Module
*Rudimentary* support as a module exists; functions / variables offered can be found in `amdgpu_stats.utils`
Demonstration:
Introduction:
```
