[SeaBIOS] Support for QEMU's virtio modern-pio-notify option?

Sun Apr 2 17:41:36 CEST 2017

Does SeaBIOS support QEMU's modern-pio-notify option for virtio devices?  My VM hangs
during boot when enumerating the virtio-scsi drive if I set modern-pio-notify=on.

Specifically, it spins forever in the while(!vring_more_used(vq)) loop in the call stack:

scsi_drive_setup()
cdb_get_inquiry()
...
virtio_scsi_process_op()

I get the hang with the minimal command line of:
qemu-system-x86_64 -device virtio-scsi-pci,modern-pio-notify=on

I'm using QEMU 2.8.0, and both SeaBIOS 1.10.1 and 1.10.2

Here's the debug log:
