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
To identify a PCI device unambiguously in the qfe.conf file, use the name, parent name, and the
In the first line of the previous example:
■Name = SUNW,qfe
■Parent = /pci@1f,2000/pci@2
■
In the second line in the previous example:
■Name = SUNW,qfe
■Parent = /pci@1f,2000/pci@2
