pm8001_inte...handler_intx(9)

✨ NAME ✨

pm8001_interrupt_handler_intx — the main INTx interrupt handler, bestie 💅

So this is a page from the Kernel API Manual, and it's about the function that literally handles the interrupts when your HBA is doing INTx-style (not MSI-X) things. Iconic behavior only.

🎀 SYNOPSIS 🎀

irqreturn_t pm8001_interrupt_handler_intx (int irq , void *dev_id );

That's the whole signature, no cap. Returns irqreturn_t, takes an int and a void *, and honestly that's the tea ☕

🌸 ARGUMENTS 🌸

• irq — the interrupt number. Just the number of the interrupt, that's it, that's the whole vibe 🔥
• dev_id — a sas_ha structure. The HBA gets retrieved from this sas_ha structure, so like… that's where the actual hardware info is hiding 🫶

🦋 SEE ALSO 🦋
