ENUM DPLL_LOCK_STATUS_ERROR(9)

✨ enum dpll_lock_status_error(9) ✨

So bestie, this one is from the Kernel API Manual (the enum dpll_lock_status_error(9) page, iykyk) — and it's literally just about telling you why your DPLL device's lock status changed. If the previous status change happened because something went wrong, this enum spills the tea on what the error was. These are the valid values for the DPLL_A_LOCK_STATUS_ERROR attribute. 🎀

🌸 NAME 🌸

enum dpll_lock_status_error — if the previous status change was done due to a failure, this gives you the deets on the dpll device lock status error. These are the valid values for the DPLL_A_LOCK_STATUS_ERROR attribute. 💅

🦋 SYNOPSIS 🦋

enum dpll_lock_status_error {
    DPLL_LOCK_STATUS_ERROR_NONE ,
    DPLL_LOCK_STATUS_ERROR_UNDEFINED ,
    DPLL_LOCK_STATUS_ERROR_MEDIA_DOWN ,
    DPLL_LOCK_STATUS_ERROR_FRACTIONAL_FREQUENCY_OFFSET_TOO_HIGH

};

👑 CONSTANTS 👑

• DPLL_LOCK_STATUS_ERROR_NONE — ok so the dpll device lock status changed and there was literally no error at all. clean. ✨
• DPLL_LOCK_STATUS_ERROR_UNDEFINED — the dpll device lock status changed because of an undefined error 😭. The driver fills this value up in case it is not able to obtain a suitable exact error type. Basically "idk bestie, something happened" energy.
• DPLL_LOCK_STATUS_ERROR_MEDIA_DOWN — the dpll device lock status changed because the associated media got down. This may happen for example if the dpll device was previously locked on an input pin of type PIN_TYPE_SYNCE_ETH_PORT. 💀
• DPLL_LOCK_STATUS_ERROR_FRACTIONAL_FREQUENCY_OFFSET_TOO_HIGH — the FFO (Fractional Frequency Offset) between the RX and TX symbol rate on the media got too high 🔥. This may happen for example if the dpll device was previously locked on an input pin of type PIN_TYPE_SYNCE_ETH_PORT.

ngl that last one is a whole mouthful of a constant name, but she's iconic and she knows it 💅
