STRUCT IRQ_CHIP_REGS(9)

💅 struct irq_chip_regs(9) 💅

okay so bestie, welcome to the Kernel API Manual, this is the struct irq_chip_regs page and it is literally about register offsets for struct irq_gci — tiny little offset numbers that tell you where each register lives relative to reg_base. no cap, that's the whole vibe ✨ (this one ships out of ./include/linux, in case you were wondering 🫶)

🌸 NAME 🌸

struct irq_chip_regs — register offsets for struct irq_gci

like, that's it, that's the name, and honestly? iconic. 👑

---

✨ SYNOPSIS ✨

struct irq_chip_regs {
    unsigned long           enable;
    unsigned long           disable;
    unsigned long           mask;
    unsigned long           ack;
    unsigned long           eoi;
    unsigned long           type;
 };

look at her. six unsigned long fields, all lined up, all behaving. main character struct energy fr fr 💖

🦋 Members 🦋

so every single one of these is a register offset to reg_base — say it with me: offset to reg_base — and here's the whole cast:

• enable — the enable register offset to reg_base 🌈
• disable — the disable register offset to reg_base 💜
• mask — the mask register offset to reg_base 🎀
• ack — the ack register offset to reg_base ⭐
• eoi — the eoi register offset to reg_base 🍓
• type — the type configuration register offset to reg_base 🧚

six fields, six offsets, zero drama. we love a consistent queen 💅

ngl this page is short but she ate. no bugs, no warnings, no undefined behaviour — just offsets. a rare and blessed moment 😭🫶

and that's the whole page!! this cutie lives in ./include/linux and the date on the tin is October 2026, under the Kernel API Manual banner — mwah, bye bestie, slay your irq handling 💖🎀🦋👑
