This series is again preliminray work to ease packed ring
layout integration.
Main changes are using vector buffres also in the dequeue
path, and perform IOVA to HVA translation at vectors fill
time.
I still have to run more benchmarks, but PVP benchmarks does
not show performance changes.
Good thing is that it saves ~140 further lines.
Changes since v2:
=================
- check vec_id doesn't overflow (Tiwei)
- Fix perm parameters passed to fill_vec_buf (Tiwei)
- Remove extra space in variable assignation (Tiwei)
Maxime Coquelin (7):
vhost: use shadow used ring in dequeue path
vhost: make gpa to hpa failure an error
vhost: use buffer vectors in dequeue path
vhost: translate iovas at vectors fill time
vhost: improve prefetching in dequeue path
vhost: prefetch first descriptor in dequeue path
vhost: improve prefetching in enqueue path
