libnvme(9)

💅 libnvme(9) — like, the page you're literally on rn

okay so bestie, you're reading a page from the API Manual for libnvme, section 9 of the manual set. And today's main character is a struct. Yes, a struct. She's giving supporting-role energy but she's iconic to the plot, iykyk. 🎀

---

✨ NAME ✨

struct nvme_lm_io_submission_queue_data — the I/O Submission Queue data structure, fr fr.

She's the vibe check on all the fields related to the contents of the Create I/O Submission Queue command that created an I/O Submission Queue. Like, somebody made that queue, and this struct is the receipts. 🧾✨

---

🌸 SYNOPSIS 🌸

Bestie, here's the whole glow-up, field by field, exactly as written:

struct nvme_lm_io_submission_queue_data {
    __le64 iosqprp1;
    __le16 iosqqsize;
    __le16 iosqqid;
    __le16 iosqcqid;
    __le16 iosqa;
    __le16 iosqhp;
    __le16 iosqtp;
    __u8 rsvd20[4];
 };

No, your eyes aren't deceiving you, that last brace is indented one space. She's quirky like that. Copy it exactly, don't "fix" her 💅

👑 Members 👑

okay so now we meet the cast, one by one, and honestly? Every single one of them gets a name AND an acronym. Bougie behavior. Let's go:

• iosqprp1 — I/O Submission PRP Entry 1 (IOSQPRP1). Yeah. The first PRP entry. She's the opener 🫶
• iosqqsize — I/O Submission Queue Size (IOSQQSIZE). How big the queue is, lowkey important.
• iosqqid — I/O Submission Queue Identifier (IOSQQID). Her government name 🪪
• iosqcqid — I/O Completion Queue Identifier (IOSQCQID). Which completion queue she's linked with — it's giving situationship 🔗
• iosqa — I/O Submission Queue Attributes (IOSQA). The personality traits, basically ✨
• iosqhp — I/O Submission Queue Head Pointer (IOSQHP). Where the head is at. Head empty, no thoughts, just pointer 🌸
• iosqtp — I/O Submission Queue Tail Pointer (IOSQTP). And where her tail's at — together they're the whole queue-reading vibe 😭
• rsvd20 — Reserved. She's reserved, she's mysterious, she's [4] bytes of do not touch. Not yours. Hands off. 🙈

ngl, rsvd20 is literally the "reserved" one at every group hangout — present, accounted for, and absolutely not participating. Respect her space 🎀
