# TODO

- fix freq2/mem clock on internal GPUs; report unknown
- add an interval mode; log stats to logging widget occasionally
- binding/method to save log to text file
- add vram stats: used / total
- add unit toggle/binding; `Ghz` can be fairly vague - users may prefer `Mhz`/`Hz`
  - tldr: may be wanted for precision
  - driver provides *hertz*, with modern cards is fairly excessive
  - conversion is done using `format_frequency`
    - a wrapper of `format_size` from `humanfriendly`
    - *(currently)* defaults to highest sensible unit, changing on scale.
    - often flipping between `500Mhz` / `2.6Ghz` where consistency may be preferred
- address assumptions on some statistic files
  - Clocks:
    - core/memory assumed provided by `freq1_input` and `freq2_input` respectively
    - nearby files named `freq*_label` can determine this reliably
  - Voltage:
    - similarly, `in0_input` is the assumed voltage file
    - indicated by `in*_label` with `vddgfx` inside
    - no accounting for other voltage files currently; `APUs`/other cards may differ
- `argparse` extensions
  - restore `--card` / `-c` under `argparse`
    - to skip `amdgpu` device detection
    - will expect `cardN` or `renderANNN` from `/dev/dri/`
    - provides the (AMD) GPU intended to be monitored
    - may require card/hwmon detection be separate tasks
  - preferred unit for clocks
