💖 scmi_process_event_payload(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this page is literally about scmi_process_event_payload, and the vibe is: dequeue and process an event payload. no cap, it's giving kernel event-processing main character energy 🫶

🎀 NAME 🎀

scmi_process_event_payload — dequeue and process an event payload 💅

✨ SYNOPSIS ✨

       bool scmi_process_event_payload (struct events_queue *eq , struct
       scmi_registered_events_desc *pd , struct scmi_registered_event *r_evt );

🌸 ARGUMENTS 🌸

• eq — the queue to use. this is the queue, bestie, respect her 💖
• pd — the protocol descriptor to use 🦋
• r_evt — the registered event descriptor to use 🎀

🦋 DESCRIPTION 🦋

okay so here's what's happening: this function reads an event payload from the protocol queue into the dedicated scratch buffer, fills a custom report, and then look for matching event handlers and call them ✨ it skips any unknown event (as marked by scmi_process_event_header) and, in case an anomalously sized read is detected, it just flushes the queue. literally handling the event payload situation, periodt 💅

💜 RETURN 💜

False when the queue is empty. that's it, that's the return vibe 😭
