openprom version: 'OBP 4.30.4.a 2010/01/06 14:56'

How to Display a System's Installed Memory

• To display the amount of memory that is installed on your system, use the prtconf command.

Example 9-3 Displaying a System's Installed Memory

The following example shows sample output from the prtconf command. The grep Memory command selects output from the prtconf command to display memory information only.

$ prtconf | grep Memory
Memory size: 65408 Megabytes

How to Display Default and Customized Property Values for a Device

To display both the default and customized property values for devices, use the prtconf command with the -u option. For more information about this option, see the prtconf(1M) man page.

• Display the default and customized properties of a driver.conf file.

  $ prtconf -u

  The output of the prtconf -u command displays the default and customized properties for all of the drivers that are on the system.

Example 9-4 Displaying Default

This example shows the default and custom properties for the bge.conf file. Note that vendor-provided configuration files are located in the /kernel and /platform directories, while the corresponding modified driver configuration files are located in the /etc/driver/drv directory.

$ prtconf -u

            name='bge-known-subsystems' type=int items=16
            name='bge-rx-rings' type=int items=1
                  value=00000010
            name='bge-tx-rings' type=int items=1
                  value=00000002 <---- system merged value 2
          Admin global properties:
             name='bge-tx-rings' type=int items=1
                  value=00000002 <---- admin value is 2
          Vendor global properties:
             name='bge-tx-rings' type=int items=1
                       value=00000001 <---- vendor value is 1

Identifying Information About Chip Multithreading Features

The psrinfo command has been modified to provide information about physical processors, in addition to information about virtual processors. This enhanced functionality has been added to identify chip multithreading (CMT) features. The new -p option reports the total number of physical processors that are in a system. Using the psrinfo -pv command will list all the physical processors that are in the system, as well as the virtual processors that are associated with each physical processor. The default output of the psrinfo command continues to display the virtual processor information for a system.

For more information, see the psrinfo(1M) man page.

For information about the procedures that are associated with this feature, see How to Display a System's Physical Processor Type.

How to Display a System's Physical Processor Type

• Use the psrinfo -p command to display the total number of physical processors on a system.

  $ psrinfo -p
  1

  Use the psrinfo -pv command to display information about each physical processor on a system, and the virtual processor that is associated with each physical processor.

  $ psrinfo -pv
  The UltraSPARC-IV physical processor has 2 virtual processors (8, 520)
  The UltraSPARC-IV physical processor has 2 virtual processors (9, 521)
  The UltraSPARC-IV physical processor has 2 virtual processors (10, 522)
  The UltraSPARC-IV physical processor has 2 virtual processors (11, 523)
  The UltraSPARC-III+ physical processor has 1 virtual processor (16)
  The UltraSPARC-III+ physical processor has 1 virtual processor (17)
  The UltraSPARC-III+ physical processor has 1 virtual processor (18)
  The UltraSPARC-III+ physical processor has 1 virtual processor (19)

  When you use the psrinfo -pv command on an x86 based system, the following output is displayed:

  $ psrinfo -pv
  The i386 physical processor has 2 virtual processors (0, 2)
  The i386 physical processor has 2 virtual processors (1, 3)

How to Display a System's Logical Processor Type

• Use the psrinfo -v command to display information about a system's processor type.

  $ psrinfo -v

  On an x86 based system, use the isalist command to display the virtual processor type.

  $ isalist
