STRUCT SCMI_PROTOCOL_EVENTS(9)

💅 struct scmi_protocol_events(9) — Kernel API Manual 🎀

okay bestie, welcome to the Kernel API Manual entry for struct scmi_protocol_events — this is the whole vibe of one SCMI protocol's event situation, like a little profile page for all the events a protocol has going on. it's giving "per-protocol description of available events" and honestly? iconic. ✨

🌸 NAME 🌸

struct scmi_protocol_events — the per-protocol description of available events, fr fr. it's the struct that tells everyone what events a protocol supports and how to handle them. 🦋

✨ SYNOPSIS ✨

struct scmi_protocol_events {
    size_t queue_sz;
    const struct scmi_event_ops     *ops;
    const struct scmi_event         *evts;
    unsigned int                    num_events;
    unsigned int                    num_sources;
};

💖 Members 💖

• queue_sz — the size, in bytes, of the per-protocol queue you're gonna use. gotta know how much room you're working with, no cap. 📏
• ops — array of the protocol-specific events operations. like, the actual how-to-do-the-thing instructions for these events. 🛠️
• evts — array of the protocol's supported events. the whole guest list, basically. 🎟️
• num_events — how many supported events are actually described in evts. gotta match the list, bestie. 🔢
• num_sources — the number of protocol's sources, and it should be greater than 0 — like, zero sources is not the vibe. ⚠️ if this isn't available at compile time, it gets provided at run-time via get_num_sources. the way that it just shows up later? flexible queen. 👑

heads up babes: num_sources should be greater than 0. if it's not known at compile time, get_num_sources comes through with it at run-time. 💅
