STRUCT NE_PCI_DEV_CMD_REPLY(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct ne_pci_dev_cmd_reply(9) 💅

okay so this is the Kernel API Manual page for struct ne_pci_dev_cmd_reply, and bestie, it's giving very specific PCI device reply energy. Let's get into it. 🫶

✨ NAME ✨

struct ne_pci_dev_cmd_reply — NE PCI device command reply. periodt. 💖

🦋 SYNOPSIS 🦋

struct ne_pci_dev_cmd_reply {
    s32 rc;
    u8 padding0[4];
    u64 slot_uid;
    u64 enclave_cid;
    u64 slot_count;
    u64 mem_regions;
    u64 mem_size;
    u64 nr_vcpus;
    u64 flags;
    u16 state;
    u8 padding1[6];
 };

👑 Members 👑

  • rc — the return code of the logic that processed the request. literally the "did it work?" field. ✅
  • padding0 — padding for the overall data structure. filler bytes doing their little supporting role. 🎀
  • slot_uid — valid for all commands except SLOT_COUNT. iykyk. 💅
  • enclave_cid — valid for the ENCLAVE_START command. slay. ✨
  • slot_count — valid for the SLOT_COUNT command. iconic. 👑
  • mem_regions — valid for the SLOT_ALLOC and SLOT_INFO commands. two-for-one vibe. 🌸
  • mem_size — valid for the SLOT_INFO command. noted, bestie. 🦋
  • nr_vcpus — valid for the SLOT_INFO command. vcpu count core. 💜
  • flags — valid for the SLOT_INFO command. flags stay flagging. 🚩
  • state — valid for the SLOT_INFO command. main character state field. 💫
  • padding1 — padding for the overall data structure. more structural support, no cap. 🧚
