STRUCT ZYNQMP_IPI_PDATA(9)

💖 struct zynqmp_ipi_pdata(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's from struct zynqmp_ipi_pdata(9) and it's literally the whole rundown on the ZynqMP IPI agent platform data. no cap, it's giving "the blueprint of the mailbox situation." let's get into it 🫶

---

🌸 NAME 🌸

struct zynqmp_ipi_pdata — a description of a ZynqMP IPI agent's platform data, bestie. that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

struct zynqmp_ipi_pdata {
    struct device *dev;
    int irq;
    unsigned int irq_type;
    unsigned int method;
    u32 local_id;
    int virq_sgi;
    int num_mboxes;
    struct zynqmp_ipi_mbox ipi_mboxes[];
 };

like… look at her. iconic struct, no notes 💅

🎀 Members 🎀

okay so every field, one by one, because we do NOT skip 🍓

• dev — the device pointer that corresponds to the Xilinx ZynqMP IPI agent. like, which device is this even 👑
• irq — the IPI agent interrupt ID. the interrupt's whole identity fr fr
• irq_type — the IPI SGI or SPI IRQ type. pick a lane bestie 💫
• method — the IPI SMC or HVC that's gonna be used. choose your fighter 🔥
• local_id — the local IPI agent ID. the "who am i" field 🌈
• virq_sgi — the IRQ number mapped to SGI. yes, mapped, don't ask me, that's what it says 🧚
• num_mboxes — how many mailboxes this IPI agent has. count 'em 📬
• ipi_mboxes — the IPI mailboxes of this IPI agent. the actual collection, the main character energy 💜

ngl, ipi_mboxes[] is a flexible array member — the [] is literally right there in the synopsis, so just know it's a trailing array and keep it moving 😌
