STRUCT X86_INIT_PCI(9)

💖 NAME 💖

Okay bestie, welcome to struct x86_init_pci(9) from the Kernel API Manual 💅 This whole page is about platform specific pci init functions. That's the name, that's the vibe, periodt. ✨

✨ SYNOPSIS ✨

Here's the struct in all its iconic glory — no cap, copy it exactly:

       struct x86_init_pci {
           int (*arch_init)(void);
           int (*init)(void);
           void (*init_irq)(void);
           void (*fixup_irqs)(void);
        };

🎀 Members 🎀

Lowkey this is the whole cast of function pointers, and every single one matters:

• arch_init — the platform specific pci arch init call. It's giving "architecture-specific setup," bestie. 🫶
• init — the platform specific pci subsystem init. This is the main-character init energy for the pci subsystem. 👑
• init_irq — the platform specific pci irq init. Irq setup, but make it platform specific. ⚡
• fixup_irqs — the platform specific pci irq fixup. Sometimes the irqs need a little glow-up, and this is that. 💅
