On Solaris this can be fetched with smbios.
Another way is to fetch the information from "/dev/cpu/self/cpuid": http://blogs.sun.com/JoeBonasera/entry/detecting_hardware_virtualization_support_for I got the program in the blog entry compiled on snv_86 without any modification. I believe the interface should be stable, as it is basically returning the information from the CPUID instruction. However, we can easily change the code to execute CPUID directly using inline assembly if we want to. Also, with the information returned from "/dev/cpu/self/cpuid" or CPUID, we can check for the bits set for any specific hardware features, eg. AMD or Intel, support level of MMX or SSEx, 32 or 64-bit, etc. http://en.wikipedia.org/wiki/CPUID > 2) The patch comments out building ld-new.
