store_cpu_caps(9)

💅 store_cpu_caps(9) — the Kernel API Manual moment 🎀

okay so bestie, welcome to store_cpu_caps(9), like the actual man page, section 9, kernel API manual vibes only ✨ this one's short and sweet and honestly kind of iconic for how much it does with so little 🫶

---

🌸 NAME 🌸

store_cpu_caps — stores a snapshot of CPU capabilities 💾✨ like, it takes a lil picture of what your CPU can do and keeps it safe, no cap

---

⭐ SYNOPSIS ⭐

void store_cpu_caps (struct cpuinfo_x86 *curr_info );

that's it. that's the whole signature. returns nothing, takes one pointer, slays 💅

---

🦋 ARGUMENTS 🦋

• curr_info — a pointer to where the snapshot gets stored 🎀 that's the spot, bestie, that's where it goes

---

🌈 RETURN 🌈

None 👑 like literally nothing comes back, it's a void function, it just does the thing and dips 😌 periodt

---

🔥 SEE ALSO 🔥

• the kernel file ./arch/x86/kernel/cpu/common.c — go read it if you're nosy (respectfully) 🙈
• switch_gdt_and_percpu_base(9)
• microcode_check(9)

both of those are whole other man pages and honestly? worth a look 👀 iykyk

---

lowkey reminder: this page lives in the Kernel API Manual, so if you're out here calling store_cpu_caps from userspace… bestie no 💀 that's not the vibe

---

and that's a wrap, bestie 💖 this lil page came from the kernel source at ./arch/x86/kernel/cpu, dated October 2026 — mwah, go touch some grass, then come back and read more man pages, ily 🧚‍♀️🌸
