I am performing another resurrection of an old box and just discovered that the CPU is a faster version than I had expected - pleasant surprise. But now I am confused as to what I am seeing when I cat /proc/cpuinfo. I always thought that was reported by the cpu itself - apparently not.
The motherboard is an SV266A and the CPU is AMD Athlon.
How can I tell whether my processor has a particular feature? (64-bit instruction set, hardware-assisted virtualization, cryptographic accelerators, etc.) I know that the file /proc/cpuinfo contains this information, in the flags line, but what do all these cryptic abbreviations mean?
For example, given the following extract from /proc/cpuinfo, do I have a 64-bit CPU?
When I bought my Lenovo Thinkpad 520, it had Windows installed. I promptly cleaned that out and installed Fedora 16. I recently visited the /proc/cpuinfo and, much to my surprise, discovered that it has four CPUs listed (0-3). I do not remember asking for extra CPUs when I got it, believeing I was getting only a single processor. Could this be a mistake in the cpuinfo file?
