💅 crste_origin_large(9) 🎀

okay so this is the Kernel API Manual page for crste_origin_large(9), and it's literally all about grabbing the large frame origin of a large crste. bestie, let's get into it ✨

---

✨ NAME ✨

crste_origin_large — Return the large frame origin of a large crste. that's the whole vibe 💖

---

🌸 SYNOPSIS 🌸

phys_addr_t crste_origin_large (union crste crste );

---

🎀 ARGUMENTS 🎀

• crste — The crste whose origin is to be returned. Should be either a region-3 table entry or a segment table entry, in both cases with FC set to 1 (large pages). yep, both of those cases, and FC has to be 1 for the large-page situation 🫶

---

💖 RETURN 💖

The origin of the large frame pointed to by crste, or -1 if the crste was not large (wrong table type, or FC==0). so like, if it's not giving large-frame energy, you get -1 — no cap 😭
