STRUCT LOCAL_REG(9)

✨ struct local_reg(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a little struct that describes one single register the way the local package sees it. that's it, that's the whole vibe. 🎀

---

🌸 NAME 🌸

struct local_reg — a register as described in the local package view. literally just one register, but make it documented. 💅

---

🦋 SYNOPSIS 🦋

struct local_reg {
    int pkg;
    u64 pbase;
    u32 size;
    u32 offset;
    u8 width;
    void __iomem *vbase;
    u64 val;
 };

no cap, that's the whole struct. now let's meet the members 🫶

🎀 Members 🎀

okay so every field, one by one, no skipping:

• pkg — (input) the package where the register is located. which package? that one. 📦
• pbase — (input) the IP MMIO base physical address, in the local package view. physical, bestie, don't forget it. 🔥
• size — (input) the IP MMIO size.
• offset — (input) the register offset from the IP MMIO base pbase. so like, you start at pbase and walk offset forward. 🚶‍♀️
• width — (input) the register width in byte. yes, "byte", singular, that's what it says, i'm not touching it. 💀
• vbase — (internal) the IP MMIO base virtual address. internal only, so don't go poking at it from outside, iykyk. 🙈
• val — (output) the register value. this is the one you actually came here for. 💜

quick vibe check: input means you fill it in, internal means hands off, output means it hands you something back. 🧚
