▼To Set Driver Parameters Using an ipge.conf File

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

a.Check the /etc/driver_aliases file to identify the name associated with a particular device:

#grep ipge /etc/driver_aliases ipge "pciex8086,105e"

ipge "pciex8086,105f" ipge "pci8086,105e" ipge "pci8086,105f"

b.Locate the path names and the associated instance numbers in the

/etc/path_to_inst file.

#grep ipge/etc/path_to_inst "/pci@780/pci@0/pci@1/network@0" 0 "ipge" "/pci@780/pci@0/pci@1/network@0,1" 1 "ipge" "/pci@780/pci@0/pci@8/network@0" 2 "ipge" "/pci@780/pci@0/pci@8/network@0,1" 3 "ipge" "/pci@7c0/pci@0/pci@2/network@0" 4 "ipge" "/pci@7c0/pci@0/pci@2/network@0,1" 5 "ipge" "/pci@7c0/pci@0/pci@9/network@0" 6 "ipge" "/pci@7c0/pci@0/pci@9/network@0,1" 7 "ipge"

■In this example:

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

■The number not enclosed in quotes is the instance number (shown in bold italics for emphasis).

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

■In the hardware node 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 number after the final @ character within quotes is the unit-address.

To identify a PCI-E device unambiguously in the ipge.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-E device specification.

In this example:

■parent = "/pci@7c0/pci@0/pci@2/network@0"
