snd_soc_usb_allocate_port(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual page for snd_soc_usb_allocate_port(9) 💅 — this one’s here to allocate a SoC USB port for offloading support. No cap.

✨ SYNOPSIS ✨

struct snd_soc_usb * snd_soc_usb_allocate_port (struct snd_soc_component *component , void *data );

🎀 ARGUMENTS 🎀

• component — the USB DPCM backend DAI component. that’s the one, bestie 🫶
• data — private data. keep it private, keep it cute 🔒

🦋 DESCRIPTION 🦋

So, literally, this allocates and initializes a SoC USB port. The SoC USB port is used to communicate the different USB audio devices attached, in order to start audio offloading handled by an ASoC entity. USB device plug in/out events are signaled with a notification, but don’t directly impact the memory allocated for the SoC USB port. like, the notification is doing its own thing, okay? 💀
