how to get AMD CPU identification information?

how to get AMD CPU identification information?

[Bai Shuwei]

Hi, ALL:
   On the Intel platform, we can use the CPUID instruction to get the
processor serial number which is the identification for the CPU. But
on the AMD platform, i find only can get the cpu family,model,
stepping. I think those information cannot identify one processor. So
how i can get the identification information for AMD processor, or how
i distinguish every AMD processor?


Thanks ALl

you can get the values from the "CPUID Specifications April 2008"
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/25481.pdf - basically you should be able to get all the infos you need to identify
the specifics of a processor (AMD or Intel).

you also can get the values with rdmsr - on a debian box

rtl26:~# apt-get install msr-tools
rtl26:~# modprobe msr
rtl26:~# rdmsr --decimal 16 --hexadecimal  (to read the TSC in this case)
be3163d1778

details in http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/41322.PDF  (atleast for the phenom)

you also want to grab the AMD "BIOS and Kernel Developers Guide" - there is one
for every processor - so it could be a bit painfull to figure this out for all possible processors. The one for AMD Hammer is at http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/26094.PDF

By the CPUID on the AMD system, i can get the CPU family, model,
stepping identify, and other feature identifies. I don't think those
information can not indicate an unique CPU?
