STRUCT AFE_PARAM_ID_USB_AUDIO_DEV_LPCM_FMT(9)

✨ struct afe_param_id_usb_audio_dev_lpcm_fmt(9) ✨

okay so bestie, buckle up 💖 we're in the Kernel API Manual, section 9, and the star of this page is struct afe_param_id_usb_audio_dev_lpcm_fmt — a little struct living its best life in the kernel file ./sound/soc/qcom/qdsp6/q6afe.c. It's a whole vibe, it's giving "small but mighty," and we're gonna go through it together, no cap 🫶

🎀 NAME 🎀

struct afe_param_id_usb_audio_dev_lpcm_fmt —

(and yes, the description line is literally empty up there 😭 the struct name is carrying the entire section on its back, main character energy fr fr)

---

🌸 SYNOPSIS 🌸

here's the whole thing, character for character, copy it exactly bestie:

struct afe_param_id_usb_audio_dev_lpcm_fmt {
    u32 cfg_minor_version;
    u32 endian;
};

two u32 fields. that's it. that's the struct. iconic minimalism 💅

🦋 Members 🦋

💜 cfg_minor_version

the minor version used for tracking USB audio device configuration ✨ this is the field that keeps the receipts. supported values:

• AFE_API_MINOR_VERSION_USB_AUDIO_CONFIG

one supported value, and it's that one. don't improvise 🎀

💜 endian

the endianness of this interface 🌈 that's the whole description. byte order matters, and this field is where it gets written down.

lowkey a serve that the source and version live down at the bottom of the page the whole time 🧚
