DECLARE_IDTENTRY_SYSVEC(9)

🎀 NAME 🎀

hii bestie 💖 welcome to the Kernel API Manual page for DECLARE_IDTENTRY_SYSVEC(9) — literally here to declare functions for system vector entry points, and I'm obsessed.

✨ SYNOPSIS ✨

DECLARE_IDTENTRY_SYSVEC (vector , func );

🫶 ARGUMENTS 🫶

• vector — Vector number (ignored for C) 👀
• func — Function name of the entry point ✨

💅 DESCRIPTION 💅

Declares three functions, periodt:

• The ASM entry point: asm_##func 🔥
• The XEN PV trap entry point: xen_##func (maybe unused) 🦋
• The C handler called from the ASM entry point 💖

Maps to DECLARE_IDTENTRY. No cap.
