STRUCT LEAPRAID_IOCTL_PCI_INFO(9)

🌸 NAME 🌸

struct leapraid_ioctl_pci_info — PCI device information, bestie. that's it, that's the whole vibe: it's the struct that tells you all about a PCI device 💅

✨ SYNOPSIS ✨

okay so here's the whole shape of it, no cap, copy it exactly:

struct leapraid_ioctl_pci_info {
    union {
      struct {
        u32 dev:5;
        u32 func:3;
        u32 bus:24;
      } bits;
      u32 word;
    } u;
    u32 seg_id;
 };

like… look at her. bitfields. a union. a nested struct. she's iconic fr fr 👑

🎀 Members 🎀

• u — the union that holds all the PCI bus/device/function tea ☕ it's the container, the moment, the main character.
  • u.bits.dev — the PCI device number, literally.
  • u.bits.func — the PCI function number. yes queen, give us that 3-bit field 💅
  • u.bits.bus — the PCI bus number, 24 bits of it.
  • u.word — the combined representation of PCI BDF (bus/device/function) as one single u32. so you can peek at the bits or grab the whole word, whichever your heart desires 🫶
• seg_id — the PCI segment identifier. don't forget her, she matters too 💖

ngl the union means u.bits and u.word are the same memory — it's giving "two ways to look at the same lil guy" energy ✨
