ENUM DPLL_PIN_OPERSTATE(9)

💅 enum dpll_pin_operstate(9) — the vibe check for your pin's whole personality

okay bestie, so this is a page straight out of the Kernel API Manual, and it's all about enum dpll_pin_operstate — which, no cap, defines the possible operational states of a pin with respect to its parent DPLL device, and gives you the valid values for the DPLL_A_PIN_OPERSTATE attribute. That's the whole assignment. Let's get into it 🎀

✨ NAME ✨

enum dpll_pin_operstate — defines possible operational states of a pin with respect to its parent DPLL device, and the valid values for the DPLL_A_PIN_OPERSTATE attribute. Literally the mood ring of your pin 🌈

🦋 SYNOPSIS 🦋

enum dpll_pin_operstate {
    DPLL_PIN_OPERSTATE_ACTIVE ,
    DPLL_PIN_OPERSTATE_STANDBY ,
    DPLL_PIN_OPERSTATE_NO_SIGNAL ,
    DPLL_PIN_OPERSTATE_QUAL_FAILED

};

🌸 Constants 🌸

these four are the only states a pin can be in, and honestly each one is giving a different era 💅

• DPLL_PIN_OPERSTATE_ACTIVE — pin is qualified and actively used by the DPLL. she's booked, she's busy, she's the main character 👑
• DPLL_PIN_OPERSTATE_STANDBY — pin is qualified but not actively used by the DPLL. qualified, yes; chosen for the moment, no. on the bench, still iconic 🫶
• DPLL_PIN_OPERSTATE_NO_SIGNAL — pin does not have a valid signal. nothing coming through, kind of a quiet era 😭
• DPLL_PIN_OPERSTATE_QUAL_FAILED — pin signal failed qualification (e.g. frequency or phase monitor). the signal showed up but did not pass the vibe check 💀
