Hello Sebastian, I was looking at using WFE on QEMU, found that it is implemented as a NOP, googled and I found this thread.
I am not using this for SMP, simply to implement sleep, so the busy loop is conceptually OK. Except, of course, that QEMU floors the host CPU at 100% in the idle loop. You mentioned that you might send some patches for WFE/SEV, but I haven't seen anything in the current QEMU repo. Did you get anywhere with this ?
