STRUCT PORTS_BMP(9)

💅 struct ports_bmp(9) — a Kernel API Manual moment

okay bestie, buckle up, because we're talking about <rainbow>struct ports_bmp</rainbow> from the Kernel API Manual and honestly? she's small, she's focused, she has one job and she does it. main character energy in a 32-byte trench coat. 🎀

✨ NAME ✨

struct ports_bmp — a bitmap that says which ports are crying out for service. literally a "notice me" board for ports. 💅

---

🌸 SYNOPSIS 🌸

no cap, this is the whole entire struct, copy it exactly, don't get creative:

struct ports_bmp {
    u64 status;
    u64 unused[3];
 };

yes that's it. that's the girl. two fields. iconic. ✨

---

🦋 Members 🦋

the page has a Members heading, but ngl there's nothing listed underneath it — the actual members are the ones you just saw up in the SYNOPSIS (status and unused[3]). so if you were waiting for a big dramatic member list, this is the whole thing. we move. 🫶

---

💖 Description 💖

okay so here's the tea:

struct ports_bmp is a 256 bit read only bitmap, and its whole personality is indicating ports that need service. that's it, that's the vibe check. 🔥

⚠️ bestie, do NOT write to these bits. read only means read only. hands off. 🙈

⚠️ also it must not cross a page boundary — that's a hard requirement, not a suggestion, so place her carefully. 💀

and that's the page, bestie! 🎀 this little manual page came from the ./drivers/ps3 corner of the kernel and it's dated October 2026, and yes it signs off as struct ports_bmp(9) because she knows exactly who she is. slay. 🌈👑💖
