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"
4 In the above lines:
4 The first part within the double quotes specifies the hardware node name in
the device tree.
4 The second number is the instance number.
4 The last part in double quotes is the driver name.
4 In the device path name, the last component after the last / character and
before the @ character is the device name.
4 The path name before the last component is the parent name.
4 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:
4 Name = SUNW,qfe
4 Parent = /pci@1f,2000/pci@2
4 Unit-address = 0,1
In the second line in the previous example:
4 Name = SUNW,qfe
4 Parent = /pci@1f,2000/pci@2
4 Unit-address = 1,1
In the third line in the previous example:
4 Name = SUNW,qfe
4 Parent = /pci@1f,2000/pci@2
4 Unit-address = 2,1
In the fourth line in the previous example:
