megasas_service_aen(9)

💖 megasas_service_aen(9) — Kernel API Manual, but make it cute 💖

okay so bestie, this is the megasas_service_aen(9) page from the Kernel API Manual, and it's literally about processing an event notification. no cap. 🦋

🌸 NAME 🌸

megasas_service_aen — processes an event notification. that's the whole vibe. ✨

🎀 SYNOPSIS 🎀

void megasas_service_aen (struct megasas_instance *instance , struct
megasas_cmd *cmd );

🫶 ARGUMENTS 🫶

• instance — adapter soft state, aka the adapter's cozy little state blob. 🛋️
• cmd — the AEN command completed by the ISR. 💅

🔥 DESCRIPTION 🔥

okay so for AEN, the driver sends a command down to FW that is held by the FW till an event occurs. when an event of interest occurs, FW completes the command that it was previously holding. that's the whole flow, bestie. 👑

this routine sends a SIGIO signal to processes that have registered with the driver for AEN. so if your process is on the AEN list, this is the signal moment. 📣
