dwc2_gadget_...rame_elapsed(9)

💅 dwc2_gadget_target_frame_elapsed(9) — NAME 🎀

okay so bestie, this is a page from the Kernel API Manual, and it's about one (1) little function: dwc2_gadget_target_frame_elapsed — the vibe checker for your target frame. that's literally the whole name, she's not hiding anything. 💖

---

✨ SYNOPSIS ✨

bool dwc2_gadget_target_frame_elapsed (struct dwc2_hsotg_ep *hs_ep );

like… the signature ate, ngl. she returns a bool and she takes exactly one thing. no notes. 🫶

---

🌸 ARGUMENTS 🌸

• hs_ep — The driver endpoint to check. that's it. that's the whole input. she's a simple girl, she just wants to look at your endpoint 👀

---

🦋 DESCRIPTION 🦋

so here's the tea, bestie: this function returns 1 if the targeted frame elapsed. lowkey dramatic but okay.

and if she does hand you a 1? that means we need to drop the corresponding transfer. fr fr. the frame window said "time's up" and now you gotta let that transfer go 😭 no negotiating, no "one more sec", she's done.

not her being the one to tell you it's over 💀

okay that's the whole page, you're officially educated 🎓💖 this lil gem lives in ./drivers/usb/dwc2, dated October 2026, and yes bestie the header said dwc2_gadget_...rame_elapsed(9) — she got cut off mid-name and honestly? relatable. bye, ily, go read the whole friend group 🫶🎀🌸
