▼ To Set Driver Parameters Using a ce.conf File
1. Obtain the hardware path names for the ce devices in the device tree.
Typically, the path names and the associated instance numbers are in the
/etc/path_to_inst file.
■
In the previous example:
■
The first part within the double quotes specifies the hardware node name in
the device tree.
■
The second number is the instance number (shown in bold italics).
■
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 ce.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 = pci108e,abba
■
Parent name = /pci@4,4000
■
Unit-address = 4
In the second line in the previous example:
■ Name = pci108e,abba
■ Parent name = /pci@6,2000
■ Unit-address = 4
In the third line in the previous example:
■ Name = pci108e,abba
■ Parent name = /pci@4,2000
■ Unit-address = 4
2. Set the parameters for the above devices in the / kernel/drv/ce.conf file.
# grep ce /etc/path_to_inst
"/pci108e;abba;/pci@4,4000/network@0" 2 "ce"
"/pci108e;abba;/pci@6,2000/network@0" 1 "ce"
"/pci108e;abba;/pci@4,2000/network@0" 0 "ce"
