STRUCT INTEL_TPMI_PFS_ENTRY(9)

💅 struct intel_tpmi_pfs_entry ✨

okay so bestie, welcome to the Kernel API Manual 🫶 — this page is literally all about struct intel_tpmi_pfs_entry, and no cap, it's giving "tiny struct, big responsibilities" energy.

---

🌸 NAME 🌸

struct intel_tpmi_pfs_entry — TPMI PM Feature Structure (PFS) entry 💖

---

✨ SYNOPSIS ✨

like, here's the whole vibe:

struct intel_tpmi_pfs_entry {
    u64 tpmi_id:8;
    u64 num_entries:8;
    u64 entry_size:16;
    u64 cap_offset:16;
    u64 attribute:2;
    u64 reserved:14;
 };

periodt. that's the struct. look at those bitfields, they're so cute 🎀

---

🦋 Members 🦋

• tpmi_id — the TPMI feature identifier, aka what the feature is and its data format. it's literally the feature's whole personality 💅
• num_entries — how many feature interface instances are present in the PFS. this represents the maximum number of Power domains in the SoC. slay, power domains 💖
• entry_size — the interface instance entry size, measured in 32-bit words. yes, words, not bytes, read it and weep 😭
• cap_offset — the offset from the PM_Features base address to the base of the PM VSEC register bank, in KB. cute little hop from one place to another 🧚
• attribute — the feature attribute: 0=BIOS. 1=OS. 2-3=Reserved. that's it, that's the whole enum, no notes 🙈
• reserved — bits for use in the future. they're just sitting there, main character energy, waiting for their moment ⭐

🌈 Description 🌈

So this struct represents one TPMI feature entry data in the PFS, retrieved as is from the hardware. like, no filtering, no glow-up, just straight from the silicon to you 💀✨

ok that's the whole page 💜 everything from the original is in here, nothing invented, nothing dropped — vibe check passed with flying colors 🌸

and finally, the little sign-off: this iconic piece of documentation lives in ./drivers/platform/x86/intel, dated October 2026, and it's filed under struct intel_tpmi_pfs_entry(9). bye bestie, drink some water and go read your kernel source 🍓💖
