t3_intr_handler(9)

💖 NAME 💖

Okay so welcome to the t3_intr_handler(9) page in the Kernel API Manual — yes bestie, we're in kernel API land. This icon is all about one thing: t3_intr_handler — select the top-level interrupt handler. Periodt. 💅

✨ SYNOPSIS ✨

irq_handler_t t3_intr_handler (struct adapter *adap , int polling );

🎀 ARGUMENTS 🎀

• adap — the adapter. That's the main-character arg, your adapter object.
• polling — whether using NAPI to service response queues. Like, the lil yes/no vibe check for NAPI doing response-queue duty.

🌸 DESCRIPTION 🌸

So what does it actually do? It selects the top-level interrupt handler based on the type of interrupts — and the types are MSI-X, MSI, or legacy — and also based on whether NAPI will be used to service the response queues. That's the whole glow-up: interrupt type + NAPI usage go in, top-level interrupt handler comes out. No cap. ✨
