13 \fBcpuid\fR is a very simple C program, designed to dump and extract information from the x86 CPUID instruction\.
16 \fBcpuid\fR is capable of dumping all CPUID leaves (except any unknown leaves which require special ECX values to dump all information)\. \fBcpuid\fR can only decode certain leaves, but this functionality will be expanded as the CPUID specifications provided by AMD and Intel change\.
19 \fB\-c\fR, \fB\-\-cpu\fR Index (starting at 0) of CPU to get info from
22 \fB\-d\fR, \fB\-\-dump\fR Dump a raw CPUID table
25 \fB\-f\fR, \fB\-\-parse\fR Read and decode a raw CPUID table from the file specified
28 \fB\-h\fR, \fB\-\-help\fR Print list of options
31 \fB\-\-ignore\-vendor\fR Show feature flags from all vendors
34 \fB\-\-sanity\fR Do a sanity check of the CPUID data
37 \fB\-\-vendor\fR Override the processor vendor string
40 \fB\-\-version\fR Print \fBcpuid\fR version and license
43 You can find current Intel and AMD CPUID specifications at these locations:

52 Please notify me if you notice any inconsistencies or if features you find relevant are not being decoded\.
55 If you find a bug in \fBcpuid\fR, please submit details about it to the bug tracker on GitHub: https://github\.com/tycho/cpuid/issues
58 If the bug is regarding the decoding or dumping of CPUID details, then you should include the dump\.txt and decode\.txt generated with these commands:
64 cpuid \-d \-c \-1 > dump\.txt
65 cpuid \-c \-1 > decode\.txt
72 You should also specify what revision of \fBcpuid\fR you are running\. If you don\'t know, you can find out with:
