STRUCT SCMI_EVENT(9)

✨ struct scmi_event(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for struct scmi_event(9) — yes the whole page is named after the struct, that's just how these things roll 💅

🎀 NAME 🎀

struct scmi_event — literally just Describes an event to be supported 🦋

🌸 SYNOPSIS 🌸

struct scmi_event {
    u8 id;
    size_t max_payld_sz;
    size_t max_report_sz;
 };

that's the whole vibe. three fields. no notes. iconic ✨

💖 Members 💖

• id — Event ID 🆔 (that's it, that's the field)
• max_payld_sz — Max possible size for the payload of a notification message 📦 like, the biggest it could ever be, no cap
• max_report_sz — Max possible size for the report of a notification message 📨 same deal but for the report

🔥 Description 🔥

so here's the tea ☕ — every SCMI protocol, during its initialization phase, can describe the events it wishes to support in a few struct scmi_event and pass them to the core using scmi_register_protocol_events.

that's it. that's the whole lore. the protocol shows up, says "these are my events bestie," hands over a few structs, and the core takes it from there 🫶 no extra steps, no drama, just registration main character energy 👑
