Figure 64. Configure VirtIO Capability Parameters

The following table provides a reference for all the configurable high-level parameters of the VirtIO block for F-Tile. Parameters below are dedicated to each core.

Table 104.  VirtIO High-Level Parameters
Parameter Allowed Range Default Value Description
Enable VIRTIO support True/False False Enable VIRTIO Capabilities for PFs and VFs
Enable VIRTIO Capabilities for PF0 True/False False Exposes VIRTIO Capabilities for VIRTIO Capable Devices
Enable Device Specific Capability for PF0 True/False False Enables Device Specific Capability for VIRTIO Device on PF0

The table below summarizes the parameters associated with the five VirtIO device configuration structures
