STRUCT XILINX_CPM_PCIE(9)

💅 NAME 💅

struct xilinx_cpm_pcie — bestie, it's literally the PCIe port information struct, that's the whole vibe ✨

🦋 SYNOPSIS 🦋

Okay so picture this: you're in the Kernel API Manual, and this is the struct you came for 👑

struct xilinx_cpm_pcie {
    struct device                   *dev;
    void __iomem                    *reg_base;
    void __iomem                    *cpm_base;
    struct irq_domain               *intx_domain;
    struct irq_domain               *cpm_domain;
    struct pci_config_window        *cfg;
    int intx_irq;
    int irq;
    raw_spinlock_t lock;
    const struct xilinx_cpm_variant   *variant;
 };

No cap, that field list is exact — don't be out here renaming anything, the compiler will NOT be your friend 💀

🎀 MEMBERS 🎀

Every single one of them, in order, we're not skipping a thing 🫶

• dev — the device pointer, aka the main character reference 🌟
• reg_base — Bridge Register Base, that's where the registers live 🏠
• cpm_base — CPM System Level Control and Status Register(SLCR) Base — say it with your chest, SLCR 💜
• intx_domain — legacy IRQ domain pointer, the old-school one 🎀
• cpm_domain — CPM IRQ domain pointer, the CPM-flavoured one 🦋
• cfg — holds mappings of config space window, like a little window into config space 🪟
• intx_irq — legacy interrupt number 🔢
• irq — Error interrupt number, that's a different number, don't mix them up 🙈
• lock — lock protecting shared register access, guards the shared registers with its life 💅
• variant — CPM version check pointer, so you know which CPM you're dealing with 👑
