STRUCT SMP2P_SMEM_ITEM(9)

💖 struct smp2p_smem_item(9) 💖

okay so bestie, welcome to the kernel API manual page for struct smp2p_smem_item — and yeah, it's a struct smp2p_smem_item kind of day, the Linux kernel API kind, and we're gonna get through it together 🫶

---

✨ NAME ✨

struct smp2p_smem_item — the in-memory communication structure. that's it, that's the vibe. it's literally the little shared-memory blueprint the two sides use to talk to each other 💅

---

🌸 SYNOPSIS 🌸

here's the whole glow-up, exactly as it lives in the header, no cap:

struct smp2p_smem_item {
    u32 magic;
    u8 version;
    unsigned features:24;
    u16 local_pid;
    u16 remote_pid;
    u16 total_entries;
    u16 valid_entries;
    u32 flags;
    struct {
      u8 name[SMP2P_MAX_ENTRY_NAME];
      u32 value;
    } entries[SMP2P_MAX_ENTRY];
 };

like… look at her. absolute main character energy ✨

🎀 Members 🎀

bestie, this is the important part, so pay attention — every single field, no skipping 🧚

• magic — the magic number. yes it's called magic, yes it's iconic, it's how you know you're looking at the right thing 🔥
• version — the version. gotta know which era we're in 💜
• features — the features flag — and ngl, it's currently unused, so it's just sitting there being pretty 🙈
• local_pid — processor id of the sending end. the sender, the one doing the talking 📤
• remote_pid — processor id of the receiving end. the one on the other side listening 📥
• total_entries — number of entries — and it's always SMP2P_MAX_ENTRY, like it's not even a maybe, it's a always ✨
• valid_entries — number of allocated entries. so like, how many of them are actually real and in use 🎀
• flags — flags. that's the whole description and honestly? respect for the minimalism 💀
• entries — the individual communication entries. the actual little messages living their best lives 🌈
• entries.name — name of the entry 🏷️
• entries.value — content of the entry. the actual payload, the whole point 🍓

• struct qcom_smp2p(9)
• qcom_smp2p_intr(9)

all of them live under ./drivers/soc/qcom, periodt 👑

lowkey a reminder that this is kernel-level stuff, so like… be careful, okay? not me being dramatic, it's just facts 💀
