STRUCT IL_RB_STATUS(9)

✨ struct il_rb_status(9) ✨

okay so bestie, welcome to the <pink>Kernel API Manual</pink> 💅 this one's a struct, she's tiny, she's in drivers/net/wireless/intel/iwlegacy/, and she's here to tell you about reseve buffer status host memory mapped FH registers 🎀 (yes, "reseve" — that's the original's spelling, not me being sloppy, i promise 😭)

---

🌸 NAME 🌸

struct il_rb_status — reseve buffer status host memory mapped FH registers 💖

like... that's literally her whole job. she holds the status bits, mmkay?

---

✨ SYNOPSIS ✨

struct il_rb_status {
    __le16 closed_rb_num;
    __le16 closed_fr_num;
    __le16 finished_rb_num;
    __le16 finished_fr_nam;
    __le32 __unused;
 };

that's it. four __le16s and a __le32 named __unused who is just vibing in the back not participating 🫶

---

🎀 Members 🎀

bestie these are the members, look at them, they're iconic:

• closed_rb_num — the field itself
• closed_fr_num — also a field
• finished_rb_num — a field
• finished_fr_nam — a field (yes, nam. that's what's written. no i will not be fixing it, don't @ me 🙈)
• __unused — a __le32, unused, doing nothing, main character energy honestly 👑

---

💅 Description 💅

okay so here's the tea on what each field actually means, and note the [0:11] bit ranges because those matter, no cap:

• closed_rb_num [0:11] — Indicates the idx of the RB which was closed 🌸
• closed_fr_num [0:11] — Indicates the idx of the RX Frame which was closed ✨
• finished_rb_num [0:11] — Indicates the idx of the current RB in which the last frame was written to 🦋
• finished_fr_num [0:11] — Indicates the idx of the RX Frame which was transferred 🔥

⚠️ side eye moment: the struct member is spelled finished_fr_nam up in the synopsis, but the description calls it finished_fr_num. both of these are exactly what the page says, so i'm giving you both and letting you decide how to feel about it 😭

mwah 💋 that's the page! source/version vibes come from ./drivers/net/wireless/intel/i... (truncated just like that, the terminal said so, not me 🍓) and the date is October 2026 ⭐ so like, future queen behavior fr fr. take care of her, she's struct il_rb_status(9) and she ate 👑💜
