xhci_sideband_unregister(9)

✨ NAME ✨

okay so this is xhci_sideband_unregister(9) from the Kernel API Manual, and its whole thing is: unregister sideband access to a usb device. That's the name, bestie. 💅

🌸 SYNOPSIS 🌸

void xhci_sideband_unregister (struct xhci_sideband *sb );

🎀 ARGUMENTS 🎀

• sb — sideband instance to be unregistered. That's the one getting its goodbye moment. 🫶

🦋 DESCRIPTION 🦋

It unregisters sideband access to a usb device and frees the sideband instance. Cleanup? Obsessed. ✨

After this, the endpoint and interrupter event buffers should no longer be accessed via sideband. Like, the sideband era is over, periodt. 💀

The xhci driver can now take over handling the buffers. Main character energy, honestly. 👑
