This requires a functional vIOMMU (the main pain parts being writing a Q35 machine configuration in qemu for x86 guests). No major change since the RFC, I just did not find the time to describe the full setup (Q35 x86 machine config + permissions on /dev/hugepages and /dev/vfio in the guest + ulimit -l unlimited). --=20 David Marchand David Marchand (2): bus/pci: check IO permissions for UIO only net/virtio: do not require IO permissions drivers/bus/pci/bsd/pci.c | 5 +++++ drivers/bus/pci/linux/pci.c | 10 ++++++++++ drivers/net/virtio/virtio_ethdev.c | 5 ----- 3 files changed, 15 insertions(+), 5 deletions(-) --=20 1.8.3.1
