💖 zynqmp_pm_register_notifier(9) 💖

okay bestie so this is a page straight out of the Kernel API Manual and it's all about zynqmp_pm_register_notifier — the PM API that lets a subsystem sign itself up to get pinged about one specific event/error. ✨

🌸 NAME 🌸

zynqmp_pm_register_notifier — the PM API for registering a subsystem so it gets notified about a specific event/error. literally its whole personality. 🫶

🎀 SYNOPSIS 🎀

int zynqmp_pm_register_notifier (const u32 node , const u32 event ,
const u32 wake , const u32 enable );

⭐ ARGUMENTS ⭐

  • node — the Node ID that this event is related to. the main character of the pairing, iykyk 👑
  • event — the Event Mask of the Error events you want to get notified about. pick your faves 🎯
  • wake — wake the subsystem up when it catches the event — set it to 1 for that 💤➡️🔥
  • enable — 1 turns the registration on, 0 turns it off. the on/off switch, no cap 🔘

🦋 DESCRIPTION 🦋

so what does it actually do? this function is how you register — or un-register — a particular node-event combination in firmware. that's it, that's the vibe. 💅

✨ RETURN ✨

returns a status — either success, or error + reason. so yeah, check it, don't just assume it slayed 😭
