non-root mode and preemption

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Good Morning,

I have a simple question. In KVM code: /arch/x86/kvm/x86.c when the function vcpu_enter_guest is called, the run function ( kvm_x86_ops->run(vcpu)) is called with preemption and irqs disabled. My question is, running in non-root mode with preemption and irqs disabled affects the latency of other processes or VPCUs running in the same CPU?


Thank you

Oscar
