🎀 scmi_regist...tocol_events(9) 🎀

okay so this one's from the Kernel API Manual, and it's all about registering SCMI protocol events with the core. bestie, it's giving kernel-internals main character energy, but we're gonna get through it together 💖

💖 NAME 💖

scmi_register_protocol_events — register Protocol Events with the core ✨

✨ SYNOPSIS ✨

int scmi_register_protocol_events (const struct scmi_handle *handle , u8
       proto_id , const struct scmi_protocol_handle *ph , const struct
       scmi_protocol_events *ee );

💅 ARGUMENTS 💅

• handle — the handle identifying the platform instance against which the protocol's events are registered 🫶
• proto_id — Protocol ID, literally just the protocol ID 💅
• ph — SCMI protocol handle.
• ee — a structure describing the events supported by this protocol.

🦋 DESCRIPTION 🦋

SCMI Protocols initialization code uses this to register the list of supported events and their descriptors with the notification core. it takes care to pre-allocate and store all the needed descriptors, scratch buffers and event queues. that's the whole job here, and it ate ✨

🌸 RETURN 🌸

0 on Success 💖 — that's the return value, periodt.
