sgx_free_va_slot(9)

✨ sgx_free_va_slot — free a VA slot ✨

okay so this is the sgx_free_va_slot(9) kernel API page, bestie 💅 it's a tiny little function that does exactly one thing and does it slayfully. it lives in the 9 manual, aka the Kernel API Manual — very "i'm documented, therefore i'm iconic" of it.

---

🌸 SYNOPSIS 🌸

void sgx_free_va_slot (struct sgx_va_page *va_page , unsigned int offset
);

look at her. returns void, takes two args, no drama, no cap 🎀

---

🦋 ARGUMENTS 🦋

• va_page — a struct sgx_va_page instance ✨ like, the VA page itself, the whole vibe, the main character
• offset — offset of the slot inside the VA page 📍 which slot we're freeing, told in offsets, iykyk

---

💖 DESCRIPTION 💖

Frees a slot from a struct sgx_va_page instance. that's it. that's the whole thing 🫶

she takes your va_page and your offset and hands that slot back to the void. literally the "letting go" era of kernel functions 💀 no return value, no error code, she simply does it.

🍓 friendly reminder: this page is filed under ./arch/x86/kernel/cpu/sgx, dated October 2026, and yes the header said sgx_free_va_slot(9) and the footer said sgx_free_va_slot(9) too — she's consistent, she's committed, she's got main character energy 🌈

and that's the page, bestie — free that slot, stay hydrated, and tell reclaimer_writing_to_pcmd(9) i said hi 😭💜
