STRUCT SDW_CDNS_STREAMS(9)

✨ struct sdw_cdns_streams(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's all about struct sdw_cdns_streams — literally the Cadence stream data structure 🎀

---

💖 NAME 💖

struct sdw_cdns_streams — the Cadence stream data structure. that's it, that's the vibe ✨

---

🦋 SYNOPSIS 🦋

struct sdw_cdns_streams {
    unsigned int num_bd;
    unsigned int num_in;
    unsigned int num_out;
    unsigned int num_ch_bd;
    unsigned int num_ch_in;
    unsigned int num_ch_out;
    unsigned int num_pdi;
    struct sdw_cdns_pdi *bd;
    struct sdw_cdns_pdi *in;
    struct sdw_cdns_pdi *out;
 };

like, look at her. eleven fields. main character energy fr fr 👑

🌸 Members 🌸

okay bestie let's go through the squad one by one, no cap:

• num_bd — number of bidirectional streams 💫
• num_in — number of input streams 🌈
• num_out — number of output streams ⭐
• num_ch_bd — number of output stream channels. yes, that's what it says, and we're not gonna question it, we're just gonna report it 💅
• num_ch_in — hmm. okay so this one is in the struct but the page gives it no description at all 🙈 same energy as a group chat member who never texts. it's there, that's all we know
• num_ch_out — same situation bestie 😭 it's sitting in the struct, and the page doesn't say a single word about it
• num_pdi — the total number of PDIs 🔥
• bd — the bidirectional streams themselves (struct sdw_cdns_pdi *) 🌸
• in — the input streams (struct sdw_cdns_pdi *) 🎀
• out — the output streams (struct sdw_cdns_pdi *) 🦋

ngl the field list is a little chaotic — some of these have descriptions and some are just... vibing there. we kept every single one anyway because every detail matters 💜

and that's the whole page, bestie!! this one came out of ./drivers/soundwire and it's dated October 2026 ⭐ slay, iconic, ate, no crumbs. go build something with it 💖✨🎀
