STRUCT INTEL_TPMI_INFO(9)

🌸 struct intel_tpmi_info(9) 🌸

okay so this is from the Kernel API Manual, bestie — it's the manual page for struct intel_tpmi_info, and it's literally the TPMI info holder for all the IDs in one instance. let's get into it 💅

---

✨ NAME ✨

struct intel_tpmi_info — TPMI information for all IDs in an instance 🫶

---

🦋 SYNOPSIS 🦋

struct intel_tpmi_info {
    struct intel_tpmi_pm_feature *tpmi_features;
    struct intel_vsec_device *vsec_dev;
    int feature_count;
    u64 pfs_start;
    struct oobmsm_plat_info plat_info;
    void __iomem *tpmi_control_mem;
    struct dentry *dbgfs_dir;
 };

like, that's the whole struct. no cap, that's it 👑

🎀 Members 🎀

• tpmi_features — pointer to a list of TPMI feature instances ✨
• vsec_dev — pointer to the intel_vsec_device structure for this TPMI device 💖
• feature_count — the number of TPMI instances pointed at by tpmi_features (yes, the original really does say "Number of TPMI of TPMI instances" — iconic little stutter, keeping it fr fr) 🌸
• pfs_start — start of the PFS offset for the TPMI instances in this device 🦋
• plat_info — stores platform info, which the client drivers can use 👑
• tpmi_control_mem — memory mapped IO for getting control information 🔥
• dbgfs_dir — debugfs entry pointer 🧚

---

💜 Description 💜

it stores the information for all the TPMI devices enumerated from a single PCI device. that's the whole vibe — one PCI device in, all the TPMI info collected in one struct. periodt 💅
