pcie_init_service_irqs(9)

💖 NAME 💖

okay so bestie, this is the pcie_init_service_irqs(9) page from the Kernel API Manual, and the function is here to initialize irqs for PCI Express port services. That's the name, that's the game, and we're gonna get into it. 🫶

✨ SYNOPSIS ✨

here's the signature in all its glory:

int pcie_init_service_irqs (struct pci_dev *dev , int *irqs , int mask
);

🎀 ARGUMENTS 🎀

• dev — the PCI Express port you're handling, bestie.
• irqs — the array of irqs you're gonna populate. ✨
• mask — a bitmask of port capabilities returned by get_port_device_capability, iykyk.

💅 DESCRIPTION 💅

Return value: the interrupt mode associated with the port. That's the whole description — short, sweet, and lowkey iconic. 💅
