💅 megasas_register_aen(9) — Kernel API Manual energy 💅

okay so bestie, welcome to megasas_register_aen(9) from the Kernel API Manual — manual name folded in near the top like a little name tag, not copied as a header line, because we have main character energy. ✨

✨ NAME ✨

megasas_register_aen — registers for asynchronous event notification. That's the whole vibe: signing up for async event notifs. 🎀

🌸 SYNOPSIS 🌸

int megasas_register_aen (struct megasas_instance *instance , u32
       seq_num , u32 class_locale_word );

🎀 ARGUMENTS 🎀

• instance — the adapter soft state. Think of it as the controller's little home base. 🫶
• seq_num — the starting sequence number. It's literally where the event count begins.
• class_locale_word — the class of the event.

🦋 DESCRIPTION 🦋

Okay so here's the tea: this function subscribes for AEN for events beyond seq_num. It requests to be notified if and only if the event is of type class_locale. That "if and only if" is doing a lot of heavy lifting, bestie — no extra events, no surprise pop-ups, just the specified class. 💅
