STRUCT AFE_PARAM_ID_USB_AUDIO_DEV_PARAMS(9)

💅 struct afe_param_id_usb_audio_dev_params(9) — the Kernel API Manual page, but make it make sense 🎀

okay so bestie, this is one of those pages from the Kernel API Manual (yes, that's the manual's name, no I'm not making it up) and it's literally just a tiny struct with two fields in it. Two. That's the whole thing. And honestly? She ate. Minimalist icon behavior. ✨

🌸 NAME 🌸

struct afe_param_id_usb_audio_dev_params — and that's genuinely it, the manpage gives us no one-liner description here, so we're all just gonna have to keep reading like the main characters we are 🫶

---

✨ SYNOPSIS ✨

struct afe_param_id_usb_audio_dev_params {
    u32 cfg_minor_version;
    u32 dev_token;
 };

look at her. so small. so powerful. not a single extra field. 💅

🦋 Members 🦋

• cfg_minor_version — the minor version, used for tracking USB audio device configuration. like a little label on the box so everyone knows which config era we're in. the only supported value listed here is AFE_API_MINOR_VERSION_USB_AUDIO_CONFIG — no cap, that's the one. ⭐
• dev_token — the device token of the actual end USB audio device. it's giving "ID badge for the device at the end of the line" 🎀

• struct afe_param_id_usb_audio_dev_lpcm_fmt(9)
• struct afe_param_id_usb_audio_svc_interval(9)
• q6afe_get_port_id(9)

like, that is a whole squad. a whole roster. go read them all, they're literally all connected to this one little two-field struct 🙈
