Figure 25. Multifunction and SR-IOV System Settings Parameters
Table 62.  PCIe0 Multifunction and SR-IOV System settings
Parameter Value Description
Total physical functions (PFs) 1-4

Sets the number of physical functions

Enable SR-IOV support On / Off

Enable SR-IOV support

Total virtual functions of physical function (PF VFs) 0 (default)

Set the number of VFs to be assigned to each Physical Function

Enable SRIOV for PF0 On / Off

Enable SR-IOV support on Physical Function

Number of DMA channels allocated to PF0 0 - 512

Number of DMA Channels between the host and device PF Avalon-ST / Avalon-MM ports.

Number of DMA channels allocated to each VF in PF0 0 - 512

When SRIOV support is turned on for the PF, this parameter sets the number of DMA channels allocated to each VF in the PF

Note: This parameter is active when 'Enable SR-IOV support' is set to ON and 'Enable SRIOV for PF' is also set to ON.
