💅 kvm_arch_vcpu_ioctl_run(9) — main character VCPU run energy ✨

bestie, you’re in the Kernel API Manual and this page is all about kvm_arch_vcpu_ioctl_run(9). It’s literally the main VCPU run function. We love a functional icon. 👑

🎀 NAME 🎀

kvm_arch_vcpu_ioctl_run — the main VCPU run function to execute guest code. Periodt. 💖

✨ SYNOPSIS ✨

int kvm_arch_vcpu_ioctl_run (struct kvm_vcpu *vcpu );

🫶 ARGUMENTS 🫶

• vcpu — The VCPU pointer. That’s the argument, bestie. 🫶

🌸 DESCRIPTION 🌸

Okay so, the tea: this function is called through the VCPU_RUN ioctl called from user space. It will execute VM code in a loop until the time slice for the process is used, or some emulation is needed from user space. In that case, the function will return with return value 0 and with the kvm_run structure filled in with the required data for the requested emulation. No cap, that’s the whole flow. 🔥
