l3_interrupt_handler(9)

🌸 NAME 🌸

Bestie, meet l3_interrupt_handler — the interrupt handler for l3 events 💖 This little icon lives in the Kernel API Manual, and yes, we're getting into kernel interrupt territory. Buckle up 🎀

✨ SYNOPSIS ✨

irqreturn_t l3_interrupt_handler (int irq , void *_l3 );

🎀 ARGUMENTS 🎀

• irq — the irq number, periodt 🔢
• _l3 — a pointer to the l3 structure 🫶

💖 DESCRIPTION 💖

This is the Interrupt Handler for L3 error detection — main character energy for error handling, no cap ✨

Here's the numbered flow exactly as this page lays it out (and yes, it goes 1, 2, 7 — not me side-eyeing the source, but we're keeping it real 💀):

1. Step 1: Identify the L3 clockdomain partition to which the error belongs to.
2. Step 2: Identify the slave where the error information is logged ... handle the slave event..
7. Step 7: if the slave is unknown, mask out the slave.

No cap, that's the order: 1, 2, 7. We're not editing the source, bestie — we're just reading it with love 💅
