Do you have any example of hardware? What are the performance you

Currently our target is Renesas R-Car Gen3
At the moment I don't have clean requirements, but
ideally, PV driver introduces 0% performance drop
Some time soon I will have numbers on running display/GPU
with and without zero-copy - will keep updated
PV driver with 0% performance drop sounds a stretch target. But this is
does not answer to my question. Do you have any hardware that does not
support scatter/gather or not protected by an IOMMU that will be
interfaced with PV drivers?
