STRUCT PRU_IRQ_RSC(9)

💖 struct pru_irq_rsc(9) 💖

okay bestie, welcome to the Kernel API Manual — today’s main character is struct pru_irq_rsc, and it’s literally giving PRU firmware section header for IRQ data. no cap. ✨

---

🌸 NAME 🌸

struct pru_irq_rsc — PRU firmware section header for IRQ data 🎀

---

✨ SYNOPSIS ✨

here’s the exact shape, bestie — keep the punctuation exactly as it is:

       struct pru_irq_rsc {
           u8 type;
           u8 num_evts;
           struct pruss_int_map pru_intc_map[];
        };

---

🦋 Members 🦋

• type — resource type 💅
• num_evts — number of described events 🔥
• pru_intc_map — PRU interrupt routing description 🌈

---

🧚 Description 🧚

okay so here’s the vibe: the PRU firmware blob can contain an optional .pru_irq_map ELF section, and that section provides the PRUSS interrupt mapping description. iconic. 💫

The pru_irq_rsc struct describes resource entry format. periodt. 🫶
