devnp-virtio.so

Driver for VirtIO networking device

Syntax:

io-pkt-variant -d virtio [option[,option...]] ...

where variant is v4-hc or v6-hc.

Runs on:

QNX Neutrino

Targets:

x86_64

Options:

irq=N
The IRQ of the interface. The default is automatically detected on supported hardware.
mac=XXXXXXXXXXXX
The MAC address of the controller. The default is automatically detected on supported hardware.
name=prefix
Override the default interface prefix. By default, the driver's interface names are in the form vtX, where X is an integer. By setting this option, you can change the vt to something else.
pci=N
Use the PCI VirtIO device found at the specified PCI instance. The default behavior is to detect all instances.

This option can't be used if smem is specified.

smem=XXXXXXXX
Use the MMIO VirtIO device found at the specified location, which is the starting address of the device's representation in the guest's VM.

This option can't be used if pci is specified.

Description:

The devnp-virtio.so driver supports the VirtIO network interface exported by hypervisors that follow the VirtIO standard.

Note:
The network drivers don't put entries into the /dev namespace, so a waitfor command for such an entry won't work properly in buildfiles or scripts. Use if_up -p instead; for example, if_up -p vt0.

Examples:

Start the v4 variant of io-pkt, run devnp-virtio.so to support the VirtIO networking device, and assign an IP address to the driver's interface: 
io-pkt-v4-hc -d virtio
ifconfig vt0 192.0.2.1
Start the v6 variant of io-pkt, configure devnp-virtio.so to use the MMIO VirtIO device at address 0xf0c00000 with an IRQ of 58, and assign an IP address to the driver's interface: 
io-pkt-v6-hc -d virtio smem=0xf0c00000,irq=58
ifconfig vt0 192.0.2.1

For further information about how to configure a driver that gets started by the TCP/IP stack, see the io-pkt entry.
