Did you check that virtio devices bound to uio_pci_generic still works
with legacy mode + PIO?
I had verified PIO, might under igb_uio driver.
Well, if you are unsure, please retest both cases, igb_uio and uio_pci_generic.
I still haven't got a VM with PIO, but retested MMIO with both igb_uio
and uio_pci_generic. They both works.
@Chenbo
Could you help run with PIO?
Theoretically it works with uio_pci_generic driver. I could do the test
if needed. Give me some time. Have to create a legacy VM. Now bars in
virtio device in the cloud are basically mmio.
Sure, take the time to check.
I'll wait for your confirmation, thanks.
