💅 plpks_get_wrappingfeatures — a Kernel API Manual moment

okay so bestie, we're in the Kernel API Manual today and the star of the show is plpks_get_wrappingfeatures. yes that's a mouthful, yes it's iconic, no we are not skipping it 💖

---

✨ NAME ✨

plpks_get_wrappingfeatures — literally just returns a bitmask of the wrapping features supported by the hypervisor. that's it. that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

u64 plpks_get_wrappingfeatures (void );

---

🦋 ARGUMENTS 🦋

• void — no arguments. nothing. zero. the void is the point, ngl 🙈

---

💜 DESCRIPTION 💜

so here's the tea ☕ — when initialization happens and the H_PKS_GET_CONFIG HCALL runs successfully, it reads a bitmask of the wrapping features supported by the hypervisor into the file local static wrappingfeatures variable. slay.

but listen — this is only valid when the PLPKS config structure version is >= 3. like, version 3 or higher, periodt. don't come for this function with your version 2 energy, it's not gonna work out 💀

---

⭐ RETURN ⭐

bitmask of the wrapping features supported by the hypervisor. king behavior honestly 👑
