STRUCT SOF_IPC4_PROCESS(9)

💅 struct sof_ipc4_process — yes bestie, this is from the Kernel API Manual, and it's giving process config data ✨

okay so picture this: you're deep in the SOF IPC4 topology headers and you stumble on struct sof_ipc4_process, and you're like "what IS she?". She's the process config data struct, that's what. Main character energy, no cap 🎀

🌸 SYNOPSIS 🌸

here's the whole glow-up, verbatim, don't touch a single character bestie:

struct sof_ipc4_process {
    struct sof_ipc4_base_module_cfg base_config;
    struct sof_ipc4_base_module_cfg_ext *base_config_ext;
    struct sof_ipc4_audio_format output_format;
    struct sof_ipc4_available_audio_format available_fmt;
    void *ipc_config_data;
    uint32_t ipc_config_size;
    struct sof_ipc4_msg msg;
    u32 base_config_ext_size;
    u32 init_config;
 };

like, she's a whole vibe. nine members. every single one matters. let's meet them 💖

✨ Members ✨

• base_config — the IPC base config data, aka her foundation. the blueprint. the base coat before the glitter 💅
• base_config_ext — base config extension data for module init. it's the extension, obviously, she goes further 🦋
• output_format — the output audio format. what's coming out the other side, sound-wise 🎧
• available_fmt — the available audio format(s). all the options she could serve you 🌈
• ipc_config_data — process module config data. the actual payload, the main event 🔥
• ipc_config_size — size of that process module config data. yes she knows exactly how big she is, queen behavior 👑
• msg — an IPC4 message struct containing header and data info. the envelope AND the letter 📬
• base_config_ext_size — size of the base config extension data in bytes (bytes!! not vibes!!) 🧚
• init_config — module init config type, and it's one of the SOF_IPC4_MODULE_INIT_CONFIG_TYPE_* values. pick your fighter ⭐

ngl bestie, if you're poking at this struct you're already in the deep end of the SOF IPC4 topology pool. respect. hydrate. read the header file 🫶

k that's the whole page, mwah 💋 — this lil slice of kernel API manual lives at ./sound/soc/sof, and the version/date stamp on it is October 2026. stan a struct that knows her own timestamp 💜
