kvm_mips_build_vcpu_run(9)

✨ kvm_mips_build_vcpu_run(9) ✨

okay bestie, this one is from the Kernel API Manual and it's literally all about kvm_mips_build_vcpu_run(9) — the little assembly helper that gets a guest VCPU ready to run 🏃‍♀️💨 no cap.

---

🌸 NAME 🌸

kvm_mips_build_vcpu_run — assemble the function that starts running a guest VCPU 💅

---

🎀 SYNOPSIS 🎀

void * kvm_mips_build_vcpu_run (void *addr );

---

🦋 ARGUMENTS 🦋

• addr — the address where you wanna start writing code, bestie ✍️✨

---

💖 DESCRIPTION 💖

So what this does is assemble the start of the vcpu_run function — the one that actually runs a guest VCPU 👑. And the function it builds conforms to this prototype, exactly:

int vcpu_run(struct kvm_vcpu *vcpu);

The exit from the guest and the return back to the caller? That's not handled here, bestie — it's handled by the code generated by kvm_mips_build_ret_to_host. iykyk 🫶

---

⭐ RETURN ⭐

It returns the next address after the end of the written function 📍 — like, where you'd keep writing next.
