### Additional notes
- To read motherboard sensors on ASUS ROG STRIX B550-A GAMING, as of Linux 6.16 you need to booth with kernel parameter of `acpi_enforce_resources=lax`. On Fedora it can be added by appending it to `/etc/kernel/cmdline`.
- You need to be able to read RAPL as user. Create in `/etc/tmpfiles.d/intelrapl.conf` with content `z- /sys/class/powercap/intel-rapl:0/energy_uj 0440 root uucp - -`. Adjust uucp to whatever group applicable, like `dialout`.
- `compile_commands.json` is so clang understands this project, so we can edit it with helix/neovim. Generated with `bear -- make`, make sure to run `make clean` beforehand.
