✨ NAME ✨

xhci_sideband_register — register a sideband for a usb device. periodt. 💅

---

📜 SYNOPSIS 📜

Here's the exact signature, copy-paste energy and all:

struct xhci_sideband * xhci_sideband_register (struct usb_interface
*intf , enum xhci_sideband_type type , int (*notify_client)(struct
usb_interface *intf, struct xhci_sideband_event *evt) );

---

🎀 ARGUMENTS 🎀

• intf — the usb interface associated with the sideband device. that's the whole assignment, bestie. 🦋
• type — the manpage literally says -- undescribed -- here. not me making up lore, it's giving mystery-parameter energy. 💀
• notify_client — also -- undescribed -- in the manpage. zero extra tea, so I'm not inventing any. 🙈

---

💅 DESCRIPTION 💅

This one allows for clients to utilize XHCI interrupters and fetch transfer and event ring parameters for executing data transfers. that's the plot, and honestly? kinda iconic. 🔥

---

🔁 RETURN 🔁

You get a pointer to a new xhci_sideband instance if successful. NULL otherwise. simple, clean, slay. ✨
