3 cpuid \- print processor information
10 Intel and compatible processors since the
12 (or late 486) provide the
14 instruction that returns information about the chip. The
16 program enumerates and prints this information in a simple
17 textual format. The output consists of multiple lines prefixed
18 with a keyword describing the information that follows.
22 option, the format changes to raw hexadecimal output with the
27 instruction followed by 4 colums with the output registers
36 option prints enumerated items in raw format if no
37 keyword is known instead of omitting it (default).
39 The keywords supported so far are:
42 Processor vendor string
44 .B procmodel, extmodel
45 Processor model, hexadecimal model / family id
47 .B features, extfeatures
48 Feature bits, a variable list of feature acronyms
53 .B physbits, virtbits, guestbits
54 Address lines, decimal in bits
