Setting ipg Driver Parameters Using a qfe.conf File

1.Obtain the hardware path names for the qfe devices in the device tree.

Typically the path names and the associated instance numbers will be present in the

/etc/path_to_inst file.

#grep qfe /etc/path_to_inst "/pci@1f,2000/pci@2/SUNW,qfe@0,1" 4 "qfe" "/pci@1f,2000/pci@2/SUNW,qfe@1,1" 5 "qfe" "/pci@1f,2000/pci@2/SUNW,qfe@2,1" 6 "qfe" "/pci@1f,2000/pci@2/SUNW,qfe@3,1" 7 "qfe"

■In the above lines:

■The first part within the double quotes specifies the hardware node name in the device tree.

■The second number is the instance number.

■The last part in double quotes is the driver name.

■In the device path name, the last component after the last / character and before the @ character is the device name.

■The path name before the last component is the parent name.

■The comma separated numbers after the @ character at the end represent the device and function numbers, which are together referred to as unit-address.

To identify a PCI device unambiguously in the qfe.conf file, use the name, parent name, and the unit-address for the device. Refer to the pci(4) man page for more information about the PCI device specification.

In the first line of the previous example:

■Name = SUNW,qfe

■Parent = /pci@1f,2000/pci@2

■Unit-address = 0,1

In the second line in the previous example:

■Name = SUNW,qfe

■Parent = /pci@1f,2000/pci@2

■Unit-address = 1,1
