STRUCT REG(9)

💅 struct reg(9) 💅

ok so real talk, bestie — this is a page from the Kernel API Manual, and it's literally just one little struct that goes hard. it's giving "small but mighty" energy, no cap. let's get into it 🫶

---

✨ NAME ✨

struct reg — a register descriptor, aka the lil glow-up card that tells you everything about one single register 🔥

---

🌸 SYNOPSIS 🌸

struct reg {
    u32 offset;
    u32 stride;
    u32 fcount;
    const u32 *fmask;
    const char *name;
 };

like yes, that's the whole thing, and it ate 💅

🎀 Members 🎀

okay so here's the breakdown of every single field, bestie — nothing skipped, we're thorough in this house 👑

• offset — the register offset, measured relative to the base of register memory 📍
• stride — the distance between two instances, but only if it's parameterized 👀 (so like, when there's more than one of them)
• fcount — the number of entries in the fmask array 🔢
• fmask — an array of mask values that define the position and width of the fields 🎯
• name — the upper-case name of the register 🏷️ (yes, upper-case, don't play with her)

fr fr bestie, name is upper-case. that's the vibe check on that field. 💀

and that's the whole page, iconic and complete 😭💖 this little gem lives under ./drivers/net/ipa and it's dated October 2026 — cute, right? ty for reading bestie, slay your kernel dev journey 🌸✨🎀
