STRUCT CDNSP_TRANSFER_EVENT(9)

✨ struct cdnsp_transfer_event(9) ✨

okay so bestie, welcome to the struct cdnsp_transfer_event manpage, part of the Kernel API Manual 💅 this one is short and sweet and honestly kind of iconic for it.

---

🎀 NAME 🎀

struct cdnsp_transfer_event — that's it, that's the name, no cap 🫶 (the original page literally gives no description here, so we're not gonna invent one, bestie — we stay honest)

---

🌸 SYNOPSIS 🌸

here's the literal shape of it, copy-paste vibes, don't touch:

struct cdnsp_transfer_event {
    __le64 buffer;
    __le32 transfer_len;
    __le32 flags;
 };

---

🦋 Members 🦋

• buffer — a 64-bit buffer address, or immediate data. like, it's either a pointer to somewhere or the actual data itself, and it's chill about which 😌
• transfer_len — the data length that got transferred. slay, that's the whole thing ✨
• flags — okay so this field is a little main character: it's interpreted differently depending on the type of TRB. so like, don't assume one meaning, the TRB type decides the vibe check 🫡
