ENUM MEI_PG_EVENT(9)

✨ enum mei_pg_event(9) ✨

okay so bestie, buckle up, because we're diving into enum mei_pg_event from the Kernel API Manual — it's the little enum that tracks power gating transition events and honestly it's giving backstage-pass energy 🎟️✨

Basically it's the vibe check for where the driver is at during a power gating transition. no cap, it's smol but it matters 💅

🌸 SYNOPSIS 🌸

enum mei_pg_event {
    MEI_PG_EVENT_IDLE ,
    MEI_PG_EVENT_WAIT ,
    MEI_PG_EVENT_RECEIVED ,
    MEI_PG_EVENT_INTR_WAIT ,
    MEI_PG_EVENT_INTR_RECEIVED

};

look at her go 🫶 five constants, all iconic, all doing their own thing.

🎀 Constants 🎀

• MEI_PG_EVENT_IDLE — the driver is not in a power gating transition rn. she's just chilling, main character energy, nothing happening 😌
• MEI_PG_EVENT_WAIT — the driver is waiting for a pg event to complete. like sitting by the phone fr fr ⏳
• MEI_PG_EVENT_RECEIVED — the driver received the pg event!! it arrived, we love that for her 💖
• MEI_PG_EVENT_INTR_WAIT — the driver is waiting on a pg event interrupt this time. different wait, same suspense 🙈
• MEI_PG_EVENT_INTR_RECEIVED — the driver received the pg event interrupt. delivered, slay 🔥
