✨ kvm_handle_guest_debug(9) ✨

okay so bestie, this is the Kernel API Manual page for kvm_handle_guest_debug(9), and it is literally the main character energy for debug exception handling 💅

---

🌸 NAME 🌸

kvm_handle_guest_debug — handle a debug exception instruction 🐛✨

---

🦋 SYNOPSIS 🦋

int kvm_handle_guest_debug (struct kvm_vcpu *vcpu );

---

🎀 ARGUMENTS 🎀

• vcpu — the vcpu pointer. like, the pointer to the vcpu, no cap 🫶

---

💖 DESCRIPTION 💖

okay so the tea is: we route all debug exceptions through the same handler. every single one, same vibe, same handler ✨

if both the guest and host are using the same debug facilities, it will be up to userspace to re-inject the correct exception for guest delivery. so yeah, that handoff is userspace’s moment to shine 💫

---

🔥 RETURN 🔥

it returns 0 (while setting vcpu->run->exit_reason) — that’s the whole return arc, bestie 😌
