✨ xhci_sideband_get_event_buffer ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally about xhci_sideband_get_event_buffer — the function that hands you the event buffer for your device, no cap. 💅

---

🎀 NAME 🎀

xhci_sideband_get_event_buffer — return the event buffer for this device 🫶

---

🌸 SYNOPSIS 🌸

struct sg_table * xhci_sideband_get_event_buffer (struct xhci_sideband
*sb );

---

🦋 ARGUMENTS 🦋

• sb — the sideband instance for this usb device. that's your main character right there, she's the whole vibe check for the call ✨

---

💖 DESCRIPTION 💖

so here's the tea: if a secondary xhci interrupter is set up for this usb device, then this function returns the address of the event buffer where xHC writes the transfer completion events. it's giving "here's where the receipts live" 😭🔥

⚠️ okay listen — the caller needs to free the returned sg_table. that part is on you, bestie. no forgetting, no leaving it hanging, we don't do leaks in this house 🙈

---

⭐ RETURN ⭐

struct sg_table * if successful. NULL otherwise. that's it, that's the whole mood 💀✨
