If virtio interface attached to vfio-noiommu driver then do not parse for virtio resource. Instead exit with return 0;
Note: Applicable for virtio spec 0.95. Signed-off-by: Santosh Shukla <sshukla at mvista.com> --- v4-->v5: - added _NOIOMMU drv check for lagecy virtio. No need for resource_init in vfio case. And resource_pasrsing/interface validation done by pci_eal module for pmd driver. drivers/net/virtio/virtio_pci.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/net/virtio/virtio_pci.c b/drivers/net/virtio/virtio_pci.c index 537c552..520e540 100644 --- a/drivers/net/virtio/virtio_pci.c +++ b/drivers/net/virtio/virtio_pci.c @@ -514,7 +514,9 @@ virtio_resource_init_by_ioports(struct rte_pci_device *pci_dev) static int legacy_virtio_resource_init(struct rte_pci_device *pci_dev) { - if (virtio_resource_init_by_uio(pci_dev) == 0) + if (pci_dev->kdrv == RTE_KDRV_VFIO_NOIOMMU) + return 0; + else if (virtio_resource_init_by_uio(pci_dev) == 0) return 0; else return virtio_resource_init_by_ioports(pci_dev); -- 1.7.9.5
