Chapter 3 Configuring ipge and e1000 Driver Parameters 27
▼ 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:
b. Locate the path names and the associated instance numbers in the
/etc/path_to_inst file.
■ 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"
# grep ipge /etc/driver_aliases
ipge "pciex8086,105e"
ipge "pciex8086,105f"
ipge "pci8086,105e"
ipge "pci8086,105f"
# 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"
