nfp_net_irqs_alloc(9)

✨ NAME ✨

Welcome to the nfp_net_irqs_alloc(9) page in the Kernel API Manual, bestie 💖. This function is literally the one that allocates MSI-X irqs. No cap, that's the whole name vibe.

🌸 SYNOPSIS 🌸

Okay so the signature is right here, character for character, fr fr:

unsigned int nfp_net_irqs_alloc (struct pci_dev *pdev , struct
       msix_entry *irq_entries , unsigned int min_irqs , unsigned int
       wanted_irqs );

🦋 ARGUMENTS 🦋

• pdev — PCI device structure. Like, the actual PCI device struct, not just a vibe check 💅.
• irq_entries — Array to be initialized and used to hold the irq entries. It's giving "fill me up with irq entries" energy, and yes, it gets initialized ✨.
• min_irqs — Minimal acceptable number of interrupts. The absolute floor. The "I will accept no less" number, periodt.
• wanted_irqs — Target number of interrupts to allocate. The dreamy goal number 🔥.

💜 RETURN 💜

Number of irqs obtained or 0 on error. That's the return contract, bestie: success hands you the count, error hands you 0 😭. Periodt.
