STRUCT PWRSEQ_UNIT_DATA(9)

💖 NAME 💖

okay bestie, welcome to the struct pwrseq_unit_data(9) page from the Kernel API Manual — and it's literally the configuration of a single power sequencing unit. One unit, one little config card, all the sequencing vibes. slay.

✨ SYNOPSIS ✨

here's the exact struct, no cap:

       struct pwrseq_unit_data {
           const char *name;
           const struct pwrseq_unit_data **deps;
           pwrseq_power_state_func enable;
           pwrseq_power_state_func disable;
        };

🎀 Members 🎀

• name — the name of the unit. iconic little label, fr.
• deps — the units that must be enabled before this one and disabled after it, in the order they come in this array. This array must be NULL-terminated. 🚨
• enable — callback running the part of the power-on sequence provided by this unit. power-up main character energy.
• disable — callback running the part of the power-off sequence provided by this unit. goodbye sequence, but make it coordinated.

🫶 real talk: deps is not playing about that NULL termination — it must be NULL-terminated, periodt.
