DEFINE_IDTENTRY_NOIST(9)

💅 DEFINE_IDTENTRY_NOIST 💅

Hey bestie, welcome to the Kernel API Manual ✨ — this one's a little x86 macro situation and honestly it's giving "quiet but crucial," so let's get into it 🫶

---

🌸 NAME 🌸

DEFINE_IDTENTRY_NOIST — the macro that emits code for NOIST entry points that belong to an IST entry point (MCE, DB) 👑

---

🎀 SYNOPSIS 🎀

DEFINE_IDTENTRY_NOIST (func );

---

🦋 ARGUMENTS 🦋

• func — the function name of the entry point, no cap. It must be the exact same as the function name of the corresponding IST variant, like, literally identical or it's not gonna slay 💀

---

⭐ DESCRIPTION ⭐

Okay so here's the tea: this macro maps to DEFINE_IDTENTRY_RAW. That's it, that's the whole lore ✨
