With AMD we just have IRQ/NMI/SMI, and it's important to handle SMI in check_nested_events because you can turn SMIs into vmexit without stuff such as dual-monitor treatment. On the other hand there is no MTF and we're not handling exceptions yet. So, since SMIs should be pretty rare anyway, I'd rather just add a comment detailing the correct order and why we're not following it. The minimal fix would be to move SMI above the preemption timer, right? Paolo
