STRUCT SND_SOF_PLATFORM_STREAM_PARAMS(9)

🌸 NAME 🌸

struct snd_sof_platform_stream_params — the platform-dependent stream params, aka the little struct that holds all the "it depends on your hardware, bestie" bits 💅

It's from the Kernel API Manual, and honestly? She's niche, she's specific, she's giving "you only find me if you're already deep in the audio stack" energy 🎀

✨ SYNOPSIS ✨

struct snd_sof_platform_stream_params {
    u32 phy_addr;
    u16 stream_tag;
    bool use_phy_address;
    bool no_ipc_position;
    bool cont_update_posn;
};

Five fields, no cap. Two of them are bools doing quiet heavy lifting, one u32, one u16, and a fifth bool for the position-update girlies 🦋

💖 Members 💖

Okay so this is the part where we meet the whole cast, one by one 👑

• phy_addr — the platform-dependent address you want to use. Important detail though: it only actually gets used if use_phy_addr is true. So it's conditional main character energy, fr fr 🌈
• stream_tag — the stream tag to use. That's it, that's the whole vibe. It's a u16 and it tags your stream 🏷️
• use_phy_address — a bool member sitting right there in the struct. The manpage doesn't give it its own little description paragraph, so I'm not gonna invent lore for it 🙈 but yes, she is listed, she is real, she is part of the struct 💀
• no_ipc_position — set this and you're disabling the position update IPC from the firmware. Big "please stop telling me where you are" energy 😭
• cont_update_posn — continuous position update. Yes the name is abbreviated, yes we still respect her 📍

Bestie heads up: use_phy_address and use_phy_addr are not the same spelling in the original text — the member is use_phy_address and the phy_addr description refers to use_phy_addr. I'm keeping both exactly as written because we do NOT "fix" things around here 🫶

🔥 SEE ALSO 🔥

Go poke around these, they're all in the kernel file ./sound/soc/sof/sof-priv.h and they're all little icons in their own right ⭐

And that's the whole page, bestie 💜 She lives in ./sound/soc/sof, she's dated October 2026, and she's part of the Kernel API Manual — so go forth and slay your platform-dependent stream params, and remember: only use phy_addr when the flag says so 👑✨🎀
