STRUCT CDNSP_DEQUEUE_STATE(9)

💅 struct cdnsp_dequeue_state(9) — like, the whole vibe

okay so real talk, bestie, this is a page from the Kernel API Manual, section 9, and it's all about struct cdnsp_dequeue_state 🎀 — the little bundle of joy that holds the new dequeue pointer for the Transfer Ring. that's it. that's the whole personality. it's giving "small struct, big responsibility" ✨

---

🌸 SYNOPSIS 🌸

like, here's the whole thing laid out, no cap:

struct cdnsp_dequeue_state {
    struct cdnsp_segment *new_deq_seg;
    union cdnsp_trb *new_deq_ptr;
    int new_cycle_state;
    unsigned int stream_id;
 };

look at her. four fields. absolutely iconic. 👑

🦋 Members 🦋

okay so let's go through the whole cast, main character by main character 💖

• new_deq_seg — the new dequeue segment. that's her job. she's a segment. 🫶
• new_deq_ptr — the new dequeue pointer. yes it's literally named that. yes it does literally that. lowkey obsessed with the honesty here.
• new_cycle_state — the new cycle state. int-flavored. that's the whole description, don't come for me, I'm just the messenger 😭
• stream_id — the stream id for which the new dequeue pointer has been selected. so like, which stream this dequeue pointer got picked for. iykyk 💫

you want the whole friend group? 'cause the whole friend group is here, bestie. this lives in the Kernel file ./drivers/usb/cdns3/cdnsp-gadget.h, and it is surrounded by icons:

• struct cdnsp_op_regs(9)
• struct cdnsp_port_regs(9)
• struct cdnsp_intr_reg(9)
• struct cdnsp_run_regs(9)

like, that's a full roster. not one of them skipped. we love a complete ensemble cast 🌈

fr fr though — if you're poking at the Transfer Ring dequeue pointer, read the neighbors too. they all live together in ./drivers/usb/cdns3/cdnsp-gadget.h and they absolutely gossip about each other 💀

💜 the cute sign-off 💜

this little love letter ships from ./drivers/usb/cdns3 and it's dated October 2026, page struct cdnsp_dequeue_state(9). periodt. go forth and dequeue responsibly, bestie 🧚‍♀️🌸💅
