Does Solaris x86 support multiple processors?
Yes. Solaris x86 automatically detects multiple processors. The limit is at least 8 according to the HCL and by observation. The theoretical kernel limit (_ncp) is 21. Due to bus conflicts, there’s diminishing returns as you increase the number of procs. psrinfo(1M) will print the status of your processors, mpstat(1M) will report the CPU usages, and psradm(1M) can be used to take processors offline. Some people have had problems with Solaris “seeing” the extra processors, with at least one type of motherboard (HP/Compaq?). They had success with going into the BIOS utility and setting OS type to “other” for “Solaris”. With most motherboards no special BIOS settings are required. Likewise, Solaris x86 also supports Intel’s Hyperthreading (multiple logical processors). This is because most or all of the additional support required is in the motherboard and not Solaris. However, psrinfo -p will still display 1 processor (as it’s not true multi-threading).
