Solaris & UltraSPARC IV: Displaying processor information

"psrinfo" displays information about processors and virtual processors (USIV supports virtual processors; Each physical processor may support multiple virtual processors & each virtual processor may support multiple virtual processors)

"psrinfo -p" display the number of physical processors in a system; shows additional information about each physical processor with "-v" flag. -v stands for verbose mode; with -v flag, "psrinfo" displays information about processor type, floating point unit type and clock speed. If any of this information cannot be determined, psrinfo displays unknown.
