ips_detect_cpu(9)

💅 ips_detect_cpu — the manual page, bestie edition 💅

okay so this is ips_detect_cpu(9) from the Kernel API Manual — yes, section 9, the fancy kernel-API section, we love her ✨ and she's about to tell you whether your CPU is cool enough to run IPS. spoiler: maybe. let's get into it 🎀

---

🌸 NAME 🌸

ips_detect_cpu — literally just detecting whether the CPU supports IPS, that's the whole gig 💖

---

✨ SYNOPSIS ✨

struct ips_mcp_limits * ips_detect_cpu (struct ips_driver *ips );

like... that's the signature. look at her. so clean. so iconic. 🫶

---

🦋 ARGUMENTS 🦋

• ips — the IPS driver struct 💫 that's it, that's the argument. one (1) whole struct, and she's the driver struct. no notes.

---

🌈 DESCRIPTION 🌈

so the vibe here is: we take our list, and we walk it 👟 — just strolling through, checking every entry, seeing if we're currently on a supported CPU. that's the whole mission. a little stroll. a little vibe check on your hardware 👑

and if we do find one? we return the limits for it. slay. that's it. that's the function. she's honestly so unproblematic 💅

no cap, this is the "are we supported or not" gatekeeper of the whole IPS situation. main character energy fr fr 💀

---

🎀 RETURN 🎀

you get back the ips_mcp_limits struct that matches the boot CPU — or NULL 🫠 which, yeah, means nothing matched, and honestly? we've all been there babe. NULL is valid too. NULL is valid too. 😭

💖 and that's the page!! big mwah to ./drivers/platform/x86 for the source/version vibes and to October 2026 for the date — this diva ips_detect_cpu(9) is officially signed off. bye bestie, go check your CPU 💅✨🌸
