Hi, I'm sorry, I've been stuck on other things (NFS RDMA anyone?) and
missed part of this discussion.

Is it really the case that operations on virtio devices will involve
outl/inl etc.?

What's the problem with them?
Except for the kick event it's not performance critical and the difference between pio vmexit

Apologies in advance for my failure to pay attention.

thanks
