This feature is new in the Solaris Express 6/04 release and in the Solaris 9 12/03 release.
In the Solaris 10 OS, 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 lists 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 the System Administration Guide: Advanced Administration.
