plpks_is_available(9)

💅 plpks_is_available — a kernel API manual page, but make it cute

okay so bestie, welcome to plpks_is_available(9), a page from the Kernel API Manual. yes, section 9, we're doing kernel internals today and honestly? we're thriving. 🎀

---

✨ NAME ✨

plpks_is_available — literally just tells you the PLPKS availability status for the LPAR. that's it. that's the whole job. main character energy for a boolean fr fr 💖

---

🌸 SYNOPSIS 🌸

bool plpks_is_available (void );

---

🦋 ARGUMENTS 🦋

• void — no arguments. zero. none. she takes nothing and she gives you the truth. iconic. ✨

---

💜 DESCRIPTION 💜

so how does she even know? the availability of PLPKS is inferred based upon the successful execution of the H_PKS_GET_CONFIG HCALL — provided the firmware supports this feature. like, no cap, that's the vibe check right there. 🔥

the H_PKS_GET_CONFIG HCALL reads the configuration and status information related to the PLPKS. and the configuration structure? it provides a version number to inform the caller of the supported features. the way that a version number just… tells you what's supported. we love a self-aware struct. 👑

---

⭐ RETURN ⭐

• true is returned if PLPKS is available ✅
• false if not ❌

and that's the whole answer, bestie. no grey area, no "it depends", just a bool. slay. 🫶
