STRUCT SMSM_HOST(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct smsm_host(9) 💖

okay so bestie, welcome to the Kernel API Manual — today's main character is struct smsm_host, and it's literally the blueprint for representation of a remote host 🫶 like, this is how the kernel keeps a vibe check on a host that isn't, y'know, here 🦋

✨ SYNOPSIS ✨

struct smsm_host {
    struct regmap *ipc_regmap;
    int ipc_offset;
    int ipc_bit;
    struct mbox_chan *mbox_chan;
 };

no cap, that's the whole struct — four fields, all baddies, all doing their own little job 💅

🎀 Members 🎀

  • ipc_regmap — the regmap for the outgoing interrupt. it's giving "here's the map, go find your register" 🗺️✨
  • ipc_offset — the offset in ipc_regmap for that outgoing interrupt. so like, where in the map we're looking 🎯
  • ipc_bit — the bit in ipc_regmap + ipc_offset for the outgoing interrupt. yep, it's offset plus bit, the iconic duo 🔥
  • mbox_chan — the apcs ipc mailbox channel handle 📬💌 that's the little pipe your messages slide through

fr fr read the whole squad, they all reference each other and it's a whole group chat 😭💀

anyway that's the page, bestie — sourced from ./drivers/soc/qcom, dated October 2026, and yeah it's struct smsm_host(9) all the way down. slay, you ate, periodt 👑💖
