STRUCT TPMI_SST_COMMON_STRUCT(9)

🌸 struct tpmi_sst_common_struct(9) 🌸

okay so this is a page from the Kernel API Manual, and it's literally just a little struct that keeps track of stuff. bestie, it's giving "the group chat roster" energy: it's the thing that holds all the SST instances so you don't have to go hunting for them one by one 💅

---

✨ NAME ✨

struct tpmi_sst_common_struct — the place where all the SST instances live. yes, all of them. it's the mothership 🛸

---

🎀 SYNOPSIS 🎀

struct tpmi_sst_common_struct {
    int max_index;
    struct tpmi_sst_struct **sst_inst;
 };

that's it. two members. iconic minimalism ✨

---

🦋 Members 🦋

max_index

Maximum instances currently present — like, how many SST instances are actually in the building right now. it's the headcount, the guest list, the "how many of y'all are there" number 👑

sst_inst

Pointer to per package instance — a pointer-to-pointer situation, one for each package. yes it's a **, no we're not scared of it, it's just pointing at the per-package stuff 💖

---

🌸 Description 🌸

So basically this struct stores every SST Package instance — like, all of them, together, in one spot. it's the backpack that holds all the other backpacks 🎒✨ no cap, that's the whole job.

lowkey a reminder: this page is filed under ./drivers/platform/x86/intel/s... — go read the source if you want the full tea 🫖

anyway that's the whole page, thanks for coming to my TED talk 💖✨
