STRUCT IIO_DUMMY_EVENTGEN(9)

💖 NAME 💖

okay so struct iio_dummy_eventgen is the event generator specific state. That’s the whole assignment, bestie — this struct is the little state bundle for the event generator side of the IIO dummy driver. 💅

✨ SYNOPSIS ✨

This is from the Kernel API Manual, section 9, and the struct shape is exactly this:

       struct iio_dummy_eventgen {
           struct iio_dummy_regs regs[IIO_EVENTGEN_NO];
           struct mutex lock;
           bool inuse[IIO_EVENTGEN_NO];
           struct irq_domain *irq_sim_domain;
        };

🎀 Members 🎀

• regs — the irq regs we are faking. It’s a struct iio_dummy_regs array sized IIO_EVENTGEN_NO, and it’s literally the fake IRQ register state. no cap. 🔥
• lock — a struct mutex whose whole job is to protect the evgen state. do not skip the locking era, bestie. 🔒
• inuse — a bool array, inuse[IIO_EVENTGEN_NO], that’s the mask of which irqs are connected. it tracks who’s plugged in. 🫶
• irq_sim_domain — a struct irq_domain * pointing at the irq simulator domain. that’s the sim-domain vibe. ✨
