✨ STRUCT DFL_FEATURE_IRQ_CTX(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this one's a little struct from the kernel world and honestly it's giving "small but mighty" energy. Let's get into it 🫶

🌸 NAME 🌸

struct dfl_feature_irq_ctx — the dfl private feature interrupt context 💅 like,,, it's the vibe check container for one feature's interrupt situation, yk?

🦋 SYNOPSIS 🦋

struct dfl_feature_irq_ctx {
    int irq;
    struct eventfd_ctx *trigger;
    char *name;
 };

that's the whole thing, no cap. three fields, iconic, done ✨

🎀 Members 🎀

• irq — the Linux IRQ number of this interrupt 🔥 it's literally just which interrupt we're talking about, bestie.
• trigger — the eventfd_ctx context that gets signaled when the interrupt happens 📣 like it's the little messenger that goes "hey!! it happened!!" when the IRQ fires.
• name — the irq name you need when requesting the irq 🏷️ yeah you gotta have a name to request it, that's just how it is, iykyk.
