STRUCT CDNSP_EVENT_CMD(9)

💖 NAME 💖

struct cdnsp_event_cmd — okay bestie, this is the Command completion event TRB struct, and she's tiny but she's literally the main character of "did my command finish tho?" 🎀

Here's the tea on her members, no cap:

• cmd_trb — pointer to the command TRB, or the value passed by the event data trb 👀
• status — the command completion parameters and the error code (yes, both, she's multitasking ✨)
• flags — flags. That's it. That's the whole vibe 🦋

---

✨ SYNOPSIS ✨

struct cdnsp_event_cmd {
    __le64 cmd_trb;
    __le32 status;
    __le32 flags;
 };

Look at her 🫶 three fields, zero drama. __le64 for the pointer-ish thing, __le32 twice because we stay little-endian in this house 💅

🎀 Members 🎀

So this section is where the members live — and ngl, the descriptions for them are already chilling up in NAME (scroll up, babe, cmd_trb, status, flags, the whole trio 🌸). Nothing extra hiding down here, promise 🙈

Heads up bestie: this page is a kernel struct doc, so the only source of truth is the code in ./drivers/usb/cdns3/cdnsp-gadget.h. I'm not adding behaviour that isn't on the page — read the header if you want the full lore 📖

💜 and that's a wrap, babe 💜 — this icon of a page came straight out of ./drivers/usb/cdns3, dated October 2026, and she ate, fr fr. Go forth and complete your commands 👑🔥
