🦋 dwc2_uframe_schedule(9) — Kernel API Manual 🦋

okay bestie, welcome to the dwc2_uframe_schedule(9) page from the Kernel API Manual 💖 it's a short one, but we are keeping every single detail, no cap ✨

🌸 NAME 🌸

dwc2_uframe_schedule — Schedule a QH for a periodic xfer. periodt. 💅

✨ SYNOPSIS ✨

int dwc2_uframe_schedule (struct dwc2_hsotg *hsotg , struct dwc2_qh *qh
);

🎀 ARGUMENTS 🎀

• hsotg — The HCD state structure for the DWC OTG controller. literally the controller's HCD state structure, bestie 🫶
• qh — QH for the periodic transfer. that's the queue head for the periodic xfer 🎀

💅 DESCRIPTION 💅

okay so here's the tea ☕: this function calls one of the 3 sub-function depending on what type of transfer this QH is for. yup, it's giving "pick the right helper for the transfer type" energy ✨

Also adds some printing 🖨️💖. that's the whole description, short and iconic.
