Re: [Qemu-devel] SEV and WFE instructions on ARM

[Walsh, Benjamin]

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 ?

Thanks,
Ben
